Contractor shall faithfully perform the Work in accordance with the standards of professional care, skill, training, diligence and judgment provided by highly competent Contractors performing construction services of a similar nature to those described in this Agreement. Contractor shall further be responsible for the timely completion and acknowledges that a failure to comply with the standards and requirements of Work within the time limits prescribed by County may result in County's decision to withhold payment or to terminate this Agreement. 3. Term. The term of this Agreement begins upon the date of the mutual execution of this Agreement and shall continue through and until Contractor's completion of the responsibilities described in the attached Exhibits. Both of the parties to this Agreement understand and agree that the laws of the State of Colorado prohibit County from entering into Agreements which bind County for periods longer than one year. This Agreement may be extended upon mutual written agreement of the Parties. In its sole discretion, the County, by the Director of the Department of Public Works or his or her designee, may extend the time for the Contractor to complete the service or work, by not more than thirty (30) days. Such extension shall not increase the compensation to be paid to the Contractor nor change any other term herein. 4. Termination; Breach; Cure. County may terminate this Agreement for its own convenience upon thirty (30) days written notice to Contractor. Either Party may immediately terminate this Agreement upon material breach of the other party, however the breaching party shall have fifteen (15) days after receiving such notice to cure such breach. Upon termination, County shall take possession of all materials, equipment, tools and facilities owned by County which Contractor is using, by whatever method it deems expedient; and, Contractor shall deliver to County all drawings, drafts, or other documents it has completed or partially completed under this Agreement, together with all other items, materials and documents which have been paid for by County, and these items, materials and documents shall be the property of County.

Accordingly, no claim that the County has been unjustly enriched by any additional services, whether or not there is in fact any such unjust enrichment, shall be the basis of any increase in the compensation payable hereunder. In the event that written authorization and acknowledgment by the County for such additional services is not timely executed and issued in strict accordance with this Agreement, Contractor's rights with respect to such additional services shall be deemed waived and such failure shall result in non-payment for such additional services or work performed. In the event the County shall require changes in the scope, character, or complexity of the work to be performed, and said changes cause an increase or decrease in the time required or the costs to the Contractor for performance, an equitable adjustment in fees and completion time shall be negotiated between the parties and this Agreement shall be modified accordingly by Change Order.

Upon termination or expiration of this Agreement, unexpended funds advanced by County, if any, shall forthwith be returned to County.

Solicitation # B2500001 Page 5 Schedule B - Scope of Work P roject Overview Weld County is seeking Proposals for a vendor to provide construction services for the mill and overlay of the WCR 37 asphalt roadway surface from WCR 8 to SH 52. Method of Procurement Best Value: Best Value refers to a project procurement method where price and other key factors, such as quality and expertise, are considered in the evaluation and selection process. Best Value is typically achieved through an RFQ and RFP process. Delivery Method Design -Bid -Build (DBB): Design -Bid -Build (DBB) is the traditional project delivery method in which County either designs or retains a designer to furnish complete design services. Then solicits bids or proposals (advertises) and awards a separate construction contract based on the designer's completed construction documents. In DBB, the agency "owns" the details/risks of design during construction and as a result, is responsible for the cost of any errors or omissions encountered in construction. P ricing Method Unit Pricing: Unit pricing is where the contractor simply sets a price for each unit of type of work, or category of cost.

Best Value Selection Process Summary Description The following simple equation is utilized to determine the selection process scoring of the contractors which submit proposals. BV=TS+SS+CS+IS BV = Best Value Total Score (150 points maximum) TS = Technical Score (50 points maximum) SS = Schedule Score (20 points maximum) CS = Cost Score (30 points maximum) IS = Interview Score (50 points maximum) (this criterion is optional to the County) Technical Score Based upon 4 separate evaluation criteria, each with their own weighting factors. Evaluation criteria are as follows: • Scope of proposal and team. • Critical issues and similar projects. • Project control and approach. • Work location/familiarity. Schedule Score County discloses to Proposers the maximum allowable contract time acceptable, for example 150 calendar days. The earliest responsible proposed schedule scores 20 points. Other proposed schedules score based upon a ratio to the earliest. This Schedule Score is calculated by the Project Manager and provided to the selection committee members after the Technical Scores have been determined. The schedule of the successful Proposer shall form the basis for establishing the contract time, and liquidated damages would be applied after this contract time has expired. Cost Score The lowest responsible cost proposal scores 30 points. Other proposed costs score based upon a ratio to the lowest cost. The County will request Proposers to submit their cost proposal separately from their main Solicitation # B2500001 Page 11 proposal document. The Project Manager will not share the cost proposals with the other selection committee members until after the technical and schedule scores have been prior determined. Interview Score (optional) If the County decides to incorporate this criterion into the selection process, they will select the three Proposers with the highest scores to participate. In such case, these short-listed Proposers interview scores shall be added into the equation which determines the Best Value Total Score (BV). Scoring Criteria The RFQ/RFP Responses will be evaluated using the criteria listed in each Table. 1 through 3. NOTE: Each RFQ/RFP Response will be individually evaluated by a team of reviewers. Each reviewer will score using a rating scale from 1 to 5, with 1 being a poor rating, 3 being an average rating, and 5 being an outstanding rating. After the individual reviewers have scored each area, the individual reviewer scores will be totaled. The two to three highest scored RFQ/RFP Responses will be invited to participate in interviews (if required) to help the reviewers determine the final overall score and which represents the best value to the County. If interviews are determined to be necessary for the selection process, Contractors will be evaluated on the criteria shown below in Table 4. After all scores have been determined from the RFQ/RFP Response and the interview (if required), each score will be totaled for each RFQ/RFP. The highest score will be considered the top ranked proposal and best value for the County. NOTE: The highest score proposal may not be the lowest proposed cost.

Proposals must provide a project comparable to the original design either at lower cost, improved quality, or both. Proposals that lower the quality of the intended project will be rejected. Bid prices shall not be based on the anticipated approval of a Value Engineering Change Proposal (VECP). Proposals shall be submitted only by the successful bidder after contract award. If a VECP is rejected, the work shall be completed per the Contract at contract bid prices. Any delay to the project due to a VECP submittal and review shall be considered within the Contractor's control and will be non -excusable with the exception of those delays that are approved as part of the VECP. Proposals shall be categorized as VECP (Category A) or VECP (Category B). VECPs (Category A) will be all proposals that involve the design and construction of a structure including but not limited to a bridge, retaining wall, concrete box culvert, or building. A VECP (Category A will also include any proposal that would result in a change of original bid items that totals over $250,000. Alternatives investigated and not selected in the project Structural Selection Reports may be presented in a VECP if significant benefits can be demonstrated to the Engineer. In addition, design criteria and constraints listed in the Structural Selection Report cannot be modified or relaxed as part of a VECP unless significant and previously unknown benefits can be proven to the Engineer. Experimental or demonstration -type design concepts, products, structures, or elements that have not been pre -approved by the Department, in writing, for general use will be considered a VECP (Category A). Category A proposals will also result in a realized and shared cost savings to the Department. Cost savings generated to the Contract as a result of VECP offered by the Contractor and accepted by the Department shall be shared equally between the Contractor and the Department. All other VECPs that do not meet the previous requirements will be classified as a VECP (Category B). Net cost savings on VECPs shall be split equally between the Contractor and Weld County as determined in the Basis of Payment section of this specification. VECPs shall be submitted before the start of construction activities relating to the VECP. Both VECP (Category A) and VECP (Category B) will produce savings to the Department or provide improved project quality without impairing essential functions and characteristics of the facility. Essential functions include but are not limited to service life, requirements for planned future development, prior commitments to governmental agencies or the public, corridor requirements, economy of operation, ease of maintenance, desired appearance, safety, and impacts to the traveling public or to the environment during and after construction. The Contractor may submit either a full VECP or a preliminary Conceptual VECP, followed by a full proposal. These proposals are subject to rejection at any time if they do not meet the criteria outlined in this subsection. (a) Submittal of Conceptual Proposal. For a VECP (Category A) that requires a significant amount of design or other development resources, the Contractor may submit an abbreviated Conceptual Proposal for preliminary evaluation. The Engineer will evaluate Page 26 of 292 December 18, 2024 Revision of Section 104 — Scope of Work the information provided. The Contractor will then be advised in writing if any conditions or parameters of the Conceptual Proposal are found to be grounds for rejection. Preliminary review of a conceptual proposal reduces the Contractor's risk of subsequent rejection but does not commit the Department to eventual approval of the full VECP. The following information shall be submitted for each Conceptual Proposal: 1. Statement that the proposal is submitted as a Conceptual VECP. 2. General description of the difference between the existing Contract and the proposed change, and the advantages and disadvantages of each, including effects on service life, requirements for planned future development, prior commitments to governmental agencies or the public, corridor requirements, economy of operation, ease of maintenance, desired appearance, safety, and impacts to the traveling public or to the environment during and after construction.

Subsection 105.03, paragraph 7 shall be deleted and replaced with the following: Materials will be sampled and tested for Owner Acceptance by Weld County per the sampling and testing schedules and procedures contained in the Contract Documents and in CDOT's Field Materials Manual. The quantity represented by five consecutive random samples will constitute a lot whenever production schedules and material continuity permit. The Engineer may establish a lot consisting of the quantity represented by any number of consecutive random samples from one to seven inclusive when it is necessary to represent short production runs, significant material changes, or other unusual characteristics of the Work. Tests that are determined to have sampling or testing errors will not be used. The Contractor will not have the option of accepting a price reduction in lieu of producing material that complies with the Contract Documents. Continued production of nonconforming Material will not be permitted. Material, which is obviously defective, may be isolated and rejected by Weld County without regard to sampling sequence or location within a lot. Rejected material shall be removed at the Contractor's expense. Page 43 of 292 December 18, 2024 Revision of Section 105 - Control of Work S ubsection 105.03 the two paragraphs following the Table 105-2 and starting with "If P is a negative number ..." shall be deleted and replaced as follows: If P is a negative number quantity, the material will be accepted as being in conformity. In cases where one or more elements show a positive P value, such positive values will be added, and the resulting sum will be used to determine the total P value. If the total P value is between 0 (zero) and 25, the Engineer may require correction or may accept the material at a reduced price. If P is greater than 25, the Engineer may: (1) require complete removal and replacement with specification material at no additional cost to Weld County. (2) require corrective action to bring the material into conformity at no additional cost to Weld County; or (3) where the finished product is found to be capable of performing the intended purpose and the value of the finished product is not affected, permit the Contractor to leave the material in place with an appropriate price reduction to be based on engineering evaluation but not to be less than that which have occurred had a reduction been made where P=25. If the P for aggregate gradation for items 206, 304, or the gradation of hydrated lime for item 403 is 0 (zero) or greater the reduction will apply to the contract price multiplied by the Multipliers (M) listed in Table 105-3: S ubsection 105.03(c) shall be added and shall include the following: (c) Conformity to the contract of embankment construction shall be determined per the following: 1. Process Control Plan. The Contractor shall be responsible for Process Control (PC) for all embankment material on this project. The Contractor shall submit a written Process Control Plan (PCP), including a methods statement, to the Engineer for acceptance. The PCP shall include but not be limited to the following: A. Methods Statements shall include but not be limited to: • Embankment placement and alternatives for placement that may be used. • Handling of frozen materials • Trenching through embankment for placement of culverts and pipes B.

Work shall not begin until the PCP has been accepted in writing, unless otherwise approved. 2. Documentation. The Contractor shall maintain current records of process control operation activities, and tests performed. These records shall be in the form shown in the PCP, and shall include as a minimum, the Contractor or subcontractor, the number of personnel working, weather conditions, type of equipment being used, delays and their cause, and deficiencies along with corrective action taken. Such records shall cover both conforming and defective or deficient features. Additional documentation to the Engineer shall include all daily test results, daily inspection reports, daily non- compliance reports, and monthly certification reports. Copies of these records and a statement that work incorporated in the project complies with the Contract shall be submitted to the Engineer before payment for the work or upon request. Monthly certification reports shall be stamped with the seal of a Professional Engineer registered in Colorado. Failure to provide the Engineer with the necessary documentation will result in the suspension of payments on embankment until the documentation has been completed and accepted by the Engineer. Weld County Owner Acceptance (OA) documentation shall not be used as supporting documentation for the Contractor's certification. Weld County shall be responsible for OA and Independent Assurance Testing (IAT). S ubsection 105.05, paragraph 3 shall be deleted and replaced with the following: Materials will be sampled randomly and tested by the Department per subsection 106.05 and with the applicable procedures contained in CDOT's Field Materials Manual. The approximate maximum quantity represented by each sample will be as set forth in subsection 106.05. Additional samples may be selected and tested as set forth in subsection 106.05 at the Engineer's discretion. S ubsection 105.05 shall be revised to include the following: Any test result for the air voids or VMA elements greater than the distance 2 x V (see Table 105- 8) outside the tolerance limits will be designated as a separate process and the quantity it represents shall be removed and replaced with specification material at the Contractor's expense. S ubsection 105.05(f)(2), paragraph 1 shall be deleted and replaced with the following: Page 45 of 292 December 18, 2024 Revision of Section 105 — Control of Work (2) Where the finished product is found to be capable of performing the intended purpose and the value of the finished product is not affected, permit the Contractor to leave the material in place. If the material is permitted to remain in place, the PF for the process will not be greater than 0.75. The Engineer will be consulted before determining the material will be allowed to remain in place. The Engineer will also be consulted to assist in determining an appropriate pay factor. Table 105-8, "W" and "V" Factors for Various Elements shall be deleted and replaced with the following: Table 105-8 — W and V Factors for Various Elements Element V Factor W Factor 2.36 mm (No. 8) mesh and larger sieves 2.80 N/A 600 mm (No. 30) mesh sieve 1.80 N/A 0.80 N/A 75 mm (No. 200) mess sieve Gradation N/A 15 Asphalt Content 0.20 25 In -place Density 1.10 45 Joint Density 1.60 15 Voids in the Mineral Aggregate 0.60 10 Air Voids 0.60 30 Subsection 105.05(g) shall be deleted and replaced with the following: (9) Process I/DP Computation. Incentive/Disincentive payments will not be made to the Contractor for Hot Mix Asphalt. The conformance to contract of the material and elements involved shall be evaluated using the process outlined in Section 105, this subsection, and the CDOT Field Materials Manual. All sampling frequencies shall follow Table 106-2 and Stratified Random Sampling Schedules. Pay reductions shall be made in accordance with the following formula: Where: I/DP = (PF - 1)(QR)(UP)(W/100) I/DP = Incentive or Disincentive Payment PF = Pay Factor QR = Quantity in Tons of HMS Represented by the Process UP = Unit Bid Price of Asphalt Mix W = Element Factor from Table 105-8 Page 46 of 292 December 18, 2024 Revision of Section 105 — Control of Work When AC is paid for separately UP shall be: UP = [(TOnHMA)(UPHMA)+ (TonAc)(UPAc)]/ TOtIHMA Where: TonHMA = Tons of Asphalt Mix U PHMA TonAc U PAC Unit Bid Price of Asphalt Mix Tons of Asphalt Cement Unit Bid Price of Asphalt Cement For the joint density element: U P = UPHMA Where: UPHma is as defined above When AC is paid for separately UP shall be: UP = [(BTOnHMA) (BUPHMA)+(BTonAc) (BUPA0)]/ (BTOnHMA) Where: BTonHMA = Bid tons of Asphalt Mix BUPHMA = Unit Bid Price of Asphalt Mix BTonAc = Bid Tons of Asphalt Cement BUPAc = Unit Bid Price of Asphalt Cement Subsection 105.06 shall be deleted and replaced with the following: 105.06 Conformity of the Contract to Portland Cement Concrete Paving. Conformity to the Contract of all Portland Cement Concrete Pavement (PCCP), Item 412, will be determined per the following: The Plan Value for PCCP shall be 650 psi. The lower tolerance limit (TO, shall be 615 psi. Concrete less than the TL of 615 psi shall be evaluated for incentive/disincentive payment to 600 psi. Concrete flexural strength that is less than 600 psi shall be removed and replaced at the sole discretion of the Engineer. Page 47 of 292 December 18, 2024 Revision of Section 105 — Control of Work When the Engineer finds that the materials furnished, the work performed, or the finished product does not conform to the Contract, or the Pay Factor (PF) for an element's process is less than 0.75 but that reasonably acceptable work has been produced, the Engineer will determine the extent of the work that may be accepted and remain in place. The Engineer will use a Contract Modification Order to document the justification for allowing the work to remain in place and the price adjustment that will be applied. When the Engineer finds the materials furnished, work performed, or the finished product is not in conformity with the Contract, or the PF for an element's process is less than 0.75 and has resulted in an inferior or unsatisfactory product, the work or material shall be removed and replaced or otherwise corrected by and at the expense of the Contractor. When the PF for any process is 0.75 or greater, the finished quantity of work represented by the process will be accepted at the calculated pay factor. Materials will be sampled and tested by the Contractor and the Department per subsection 106.06 and with procedures contained in the CDOT Field Materials Manual. The approximate quantity represented by each sample will be as set forth in subsection 106.06, Tables 106-5. Additional samples may be selected and tested at the Engineer's discretion. A minimum of 10 days prior to the start of concrete paving, the Contractor shall perform a pre- production batch test consisting of a minimum of 10 cubic yards of the approved mix design. The pre -production batch test shall be performed using the actual batch plant and the materials to be used during the concrete paving operation. The batch plant shall have been used to produce project specified concrete mix designs within the last 12 months. Proof of the batch plant's use to produce project specified concrete pavement mix designs shall be provided to the Engineer prior to the pre -production batch test. A set of flexural strength beams and splitting tensile strength cylinders shall be taken by the Contractor and tested at 7-, 14-, and 28 -days to determine the 7-, 14-, and 28 -day average flexural and splitting tensile strengths. The average 7 -day flexural strength will be compared with the average 7 -day flexural strength from the laboratory tests for the approved mix design. The 7, 14, and 28 -day average flexural strengths will be compared to the average 7,14, and 28 -day laboratory tests for the approved mix design. A flexural strength to splitting tensile strength correlation curve shall be developed for the pre -production batch test. If the average 7 -day flexural strength is more than 10% below the average 7 -day flexural strengths from the laboratory test for the approved mix design, the Contractor shall provide a written method statement detailing the corrective actions to be taken and if necessary what changes will be made to the approved mix design. The method statement and mix design changes shall be approved by the Engineer. At the Engineer's discretion, another pre -production batch test may be required before actual production paving will be authorized to start. If the Contractor fails to obtain approval for the method statement and mix design changes, the Engineer may issue a stop work order shutting down paving production. Contract time will continue and no additional time will be added to the Project Schedule. In accordance with Section 108.09, liquated damages will be assessed if the project is not completed on time. Page 48 of 292 December 18, 2024 Revision of Section 105 — Control of Work If at any time during production, the average 7 -day flexural strength for a lot or sublot is more than 10% below the average 7 -day flexural strength from the laboratory tests for the approved mix design, the Contractor shall immediately stop the concrete paving production and provide a written method statement detailing the corrective actions to be taken and if necessary what changes will be made to the approved mix design. The method statement and mix design changes shall be approved by the Engineer. At the Engineer's discretion, another pre -production batch test may be required before actual production paving will be authorized to start. If the Contractor fails to obtain approval for the method statement and mix design changes, the Engineer may issue a stop work order shutting down paving production. Contract time will continue and no additional time will be added to the Project Schedule. In accordance with Section 108.09, liquated damages will be assessed if the project is not completed on time. Production will remain suspended until the source of the problem is identified and corrected. Each time production is suspended, corrective actions shall be proposed in writing by the Contractor and approved in writing by the Engineer before production may resume. (a) Incentive and Disincentive Payments (I/DP) will be made based on a statistical analysis that yields Pay Factors (PF) and Quality Levels (QL). The PF and QL will be made based on test results for the flexural strength element and pavement thickness (flexural strength criteria). Incentive or Disincentive payment will not be made for thickness of concrete pavement furnished by the Contractor and placed by others. Plan thickness shall be the minimum thickness provided in the plans or higher. PCCP thickness will be measured per the procedures outlined in the CDOT Field Materials Manual. The QL will be calculated for the elements of flexural strength and pavement thickness on a process basis. A process will consist of the test results from a series of random samples. Test results determined to have sampling or testing errors will not be used. All materials produced will be assigned to a process. Changes in mix design, design pavement thickness, or a break of more than 120 working days between placements will create a new process. The following is provided to clarify changes in processes for each element: 1. Construction of mainline pavement, including the shoulders if placed with the mainline, is a single process for the flexural strength element, when the mix design does not change and there is not a break of more than 120 days between placements. If the QL falls to or below 0.75, a new process will begin. 2. Construction of mainline pavement, including the shoulders if placed with the mainline, is a single process for the thickness element, when the planned thickness does not change and there is not a break of more than 120 days between placements. If the QL falls to or below 0.75, a new process will begin. 3. Construction of ramps, acceleration and deceleration lanes and shoulders placed separately are considered separate processes. Page 49 of 292 December 18, 2024 Revision of Section 105 — Control of Work 4. Changes in paving equipment, changes in placement method, changes in hauling equipment, adjustments to mix designs that do not require a new mix design, changes in weather conditions, and changes in production rate shall not create a new process in the strength or thickness elements. The Contractor and Engineer will determine element processes and what distinguishes them as processes during the Pre -pave meeting before concrete placement. (b) When it is necessary to represent material by one or two tests, each individual test shall have a PF computed per the following: If the value of the test is at or above the lower tolerance limit, then PF = 1.000. If the value of the test is below the lower tolerance limit, then: PF = 1.00 — [0.25(TL -To)/V] Where: PF = Pay Factor V = V Factor from Table 105-10 To = The Individual Test Value TL = Lower Tolerance Limit (c) The following procedures will be used to compute Incentive and Disincentive Payments (I/DP), quality levels (QL), and pay factors (PF) for processes represented by three or more tests: (1) Quality Level (QL) will be calculated according to CP-71. (2) Compute the PF for the process. When the process has been completed, the number of tests (Pn) it includes shall determine the formula to be used to compute the final pay factor per the following: A. For pavement thickness: When 3 ≤ Pn ≤ 5 If QL ≥ 85, then PF = 1.00 + (QL - 85)'0.001333 If QL < 85, then PF = 1.00 + (QL - 85)*0.005208 When 0 ≤ Pn ≤ 9 Page 50 of 292 December 18, 2024 Revision of Section 105 - Control of Work If QL ≥ 90, then PF = 1.00 + (QL - 90)*0.002000 If QL < 90, then PF = 1.00 + (QL - 90)*0.005682 When 10 ≤ Pn ≤ 25 If QL ≥ 93, then PF = 1.00 + (QL - 93)*0.002857 If QL < 93, then PF = 1.00 + (QL - 93)*0.006098 When Pn ≥ 26 If QL ≥ 95, then PF = 1.00 + (QL - 95)*0.004000 If QL < 95, then PF = 1.00 + (QL - 95)*0.006757 B. For flexural strength: When 3 ≤ Pn ≤ 5 If QL ≥ 85, then PF = 1.00 + (QL - 85)*0.002000 If QL < 85, then PF = 1.00 + (QL - 85)*0.005208 When 6 ≤ Pn ≤ 9 If QL ≥ 90, then PF = 1.00 + (QL - 90)*0.003000 If QL < 90, then PF = 1.00 + (QL - 90)*0.005682 When 10 ≤ Pn ≤ 25 If QL ≥ 93, then PF = 1.00 + (QL - 93)*0.004286 If QL < 93, then PF = 1.00 + (QL - 93)'0.006098 When Pn ≥ 26 If QL ≥ 95, then PF = 1.00 + (QL - 95)x`0.006000 If QL < 95, then PF = 1.00 + (QL — 95)x`0.006757 Compute the I/DP for the process: I/DP (PF-1)(QR)(UP) Page 51 of 292 December 18, 2024 Revision of Section 105 — Control of Work Where: QR = Quantity Represented by the process. UP = Unit Price bid for the Item. The total I/DP for an element shall be computed by accumulating the individual I/DP for each process of that element. (d) As acceptance test results become available, they will be used to calculate accumulated QL and Incentive/Disincentive Payments (I/DP) for the item. The Contractor's test results, and the accumulated calculations shall be made available to the Engineer upon request. The Engineer's test results, and the calculations will be made available to the Contractor as early as reasonably practical. Numbers from the calculations shall be carried to significant figures and rounded according to AASHTO Standard Recommended Practice R-11, Rounding Method. When the Contract specifies I/DP, the I/DP will be made to the Contractor per subsection 412.24(a). During production, Interim I/DP will be computed for information only. The Pn will change as production continues and test results accumulate. The Pn at the time and /DP is computed shall determine the formula to be used. When the Contract does not specify I/DP, no I/DP will be made to the Contractor for Portland Cement Concrete Paving. The conformance to contract of the material and elements involved shall be evaluated per Section 412. (e) The Contractor shall not have the option of accepting a price reduction or disincentive in lieu of producing specification material. Continued production of non -specification material will not be permitted. Material which is obviously defective may be isolated and rejected without regard to sampling sequence or location within a process. CO When flexural strength is indicated in the Contract, the Contractor shall, in the presence of the Engineer, begin batch testing a minimum of 10 days to the start of concrete paving to develop a correlation curve per AASHTO T198 (ASTM C496) Splitting Tensile Strength of Cylindrical Concrete Specimens. Specimens shall be evaluated per CP65-19 method B. At least three splitting tensile strength specimens and four flexural strength specimens will be tested at 3, 7, 14, and 28 days. The splitting tensile strength and flexural strength specimens for each age used to develop the correlation curve shall be cast from the same batch of concrete being placed on the project. Cores used to determine splitting tensile strengths shall only be allowed to be taken from the portion of the slab that is failing (595 psi and less) with written approval from the Engineer and in the presence of the Engineer. The Lower Tolerance Limit (TO for flexural strength shall be 615 psi. Page 52 of 292 December 18, 2024 Revision of Section 105 — Control of Work At any time during production, the Engineer may request a verification of the correlation curve developed during the batch testing for concrete paving. Verification of the curve shall be done by casting three splitting tensile specimens by the Department and testing them at the Contractor's Process Control Laboratory. The flexural strength of the correlated splitting tensile samples shall be compared to the Contractor PC flexural strength results cast from the same batch. For verification, both flexural strength specimens and splitting tensile specimens will be tested at 28 days. If the correlated flexural strength of the splitting tensile sample is not within 50 psi of the verification beam specimen's flexural strength, a new correlation curve shall be developed within 3 days for future low strength evaluations. The new correlation curve will be used for any future low flexural strength evaluations that result from concrete placed on or after the date the new correlation curve specimens are cast. Table 105 — 10 "V" Factors and Incentive Payments — Flexural Strength Criteria Element Factor Maximum Incentive Payment Lower Tolerance Limit, TL Plan Value 50 psi 3.00 % 615 psi 650 psi Flexural Strength (9) Sand Equivalence. The sand equivalence (SE) as determined by CP 37 will be considered acceptable when the running average of three consecutive tests is greater than 80 percent and no individual test result is less than 75 percent. When the running average of three consecutive SE tests falls below 80 percent or an individual SE test result falls below 75 percent, paving operations shall be suspended. The Contractor shall submit a written plan to correct the low SE test results to the Engineer for approval. The Contractor shall not continue paving operations until the Engineer approves the plan in writing and three SE test results from random samples in the stockpile are above 80 percent. (h) Pavement Surface Texture. The Contractor shall perform process control (PC) testing for the pavement surface texture depth per CP 77 Method B. All PC results for surface texture depth measurements shall be included in the Contractor's QC notebook. The start of PC testing for texturing depth shall be completed within 48 hours after the first 500 linear feet of textured pavement is placed for each lane. Paving shall not proceed until results are accepted by the Engineer. Surface texture will be considered acceptable when the average texture depth (ATD) of the panel is greater than 0.05 inch. When the ATD is less than 0.05 inches, the Contractor shall determine the area represented by this test. The area shall be determined by taking additional tests at 15 -foot intervals parallel to the centerline in each direction from the affected location until two consecutive tests are found to be within the specified limits. Any surface with unacceptable texturing exceeding 25 linear feet in any lane or shoulder greater than 8 feet wide shall be diamond ground full width of the lane. Upon the second unacceptable test result, the Contractor shall notify the Engineer, in writing, of the action taken to provide an acceptable surface texture. Page 53 of 292 December 18, 2024 Revision of Section 105 — Control of Work The Department will perform surface texture acceptance testing per CP 77 Method B. The Department will determine the panel locations where acceptance test measurements are to be taken. One stratified random acceptance test per 2,500 linear feet or fraction thereof in each lane and shoulder wider than 8 feet shall be taken with a minimum of one test per day when the Contractor is paving. When the Department locates areas of surface texture that do not meet the minimum ATD, the Contractor will be notified, and the Contractor shall identify the limits of the deficient texture depth. After the Engineer approves the limits, the Contractor shall correct the deficient surface texture by diamond grinding full lane width to provide an ATD greater than 0.05 inch at no additional cost to the project. The Contractor shall correct surface texture deficiencies before pavement smoothness testing and pavement thickness determinations. Subsection 105.07 shall be deleted and replaced with the following: 105.07 Conformity to Roadway Smoothness Criteria. Roadway smoothness testing and corrective work shall be performed as described below. The pavement smoothness category shall be MRI Category B unless shown otherwise on the plans. At least two weeks before the Pre -paving Conference the Contractor may request a change to the pavement smoothness category based on the CDOT's Design Bulletin guidelines for assigning pavement smoothness categories as found on CDOT's website at (https://www0codot0ci ov/business/designsuo ort/bulletins manuals/design-bulletins!). The Contractor shall not assume a change will be granted and shall be prepared to build the pavement according to the assigned smoothness category. Once paving operations have been started, a change in pavement smoothness category will not be made. (a) Smoothness Process Control Testing. 1. The Contractor shall perform Smoothness Process Control (SPC) testing. The test results shall be submitted to the Engineer within 48 hours of completion. SPC test results shall show the Mean Roughness Index (MRI) for each 0.10 mile. All traffic control costs associated with SPC testing will be paid for per Section 630. SPC testing shall be performed on the first 2,000 tons for the final layer of HMA or each day's paving within 24 hours after the concrete has achieved sufficient strength for PCCP. SPC testing on SMA will be tested after the sheen has been worn off. The Contractor may continue paving at his own risk. The Contractor shall not perform the SQC testing until after the concrete has attained a compressive strength of 1,000 psi if a lightweight profiler is used or 2,000 psi if a high-speed profiler is used. SPC testing shall be performed using the Contractor's inertial profiler, pursuant to the methods described in subsection 105.07(b). The Contractor's Inertial Profiler and Operator shall be certified according to CP 78. See CDOT's list of certified profilers Page 54 of 292 December 18, 2024 Revision of Section 105 — Control of Work and operators ( https://www.codot.gov/business/designsupport/matgeo/pave-smooth- testing). Production shall be suspended if SPC testing indicates that corrective work is required in accordance with subsection 105.07(e). If the SPC data becomes available after production has started for the day, suspension will begin at the end of that production day for HMA. Production will remain suspended until the problem is identified and corrected. Each time production is suspended, corrective actions shall be proposed in writing by the Contractor. Production shall not resume until the proposed corrective actions have been accepted by the Engineer in writing. When production resumes, the Contractor shall profile the first 2,000 tons of HMA or each day's paving within 24 hours after the concrete has achieved sufficient strength for PCCP. The conditions described above for suspension of work will apply. 2. The finished transverse and longitudinal surface elevation of the pavement shall be measured using a 10 -foot straightedge. Areas to be measured will be directed by the Engineer. The Contractor shall furnish an approved 10 -foot straightedge, depth gauge, and operator to aid the Engineer in testing the pavement surface. Areas showing high spots of more than 3/16 inch in 10 feet shall be marked and diamond ground until the high spot does not exceed 3/16 inch in 10 feet. (b) Initial Smoothness Acceptance Testing. The Contractor shall perform Smoothness Acceptance Testing (SA) which will be used for locating corrective work. If no corrective work is required, it will be considered the final SA testing and shall be uses for acceptance and calculation of incentive adjustments. The Contractor shall submit a Method for Handling Traffic (MHT) to the Engineer for approval at least five days in advance of SA testing. The MHT shall detail the methods for traffic control that will allow for continuous non-stop profiling of each lane to be profiled at a minimum speed of 15 mph and for the placement of triggers. The Contractor shall provide the traffic control per the approved MHT. SA testing shall not be performed without traffic control using the approved MHT. All traffic control costs associated with SA testing will be paid for per Section 630. Pavement surfaces shall be tested and accepted for longitudinal smoothness as described. 1. Testing Procedure (General). The longitudinal surface smoothness of the final pavement surface shall be tested by the Contractor per CP 74 and using the Contractor's inertial profiler (profiler). The Contractor's Profiler and Operator shall be certified according to CP 78. See CDOT's list of certified profilers and operators at https://www.codot.govibusinessidesignsupportimatgeo/pave-smooth-testing. The profiler's instrumentation shall be verified in accordance with CP 74 prior to measurements. The Contractor shall lay out a distance calibration site. The distance Page 55 of 292 December 18, 2024 Revision of Section 105 — Control of Work calibration site shall be located no more than 10 miles from the project limits. The distance calibration site shall be 1056.0 feet long and shall be on a relatively flat, straight section of pavement as approved by the Engineer. The site shall have a speed limit equal to the project's highest speed limit that allows for the profiler to operate uninterrupted. The limits of the site shall be clearly marked, and the distance shall be measured to an accuracy of +/- 1 inch. The Contractor shall provide in writing the site location to the Engineer. The cost of the distance calibration site will not be measured and paid for separately but shall be included in the work. The entire length of each through lane, climbing lane and passing lane including bridge approaches, bridge decks and intersections from the beginning to the end of the project shall be profiled in their planned final configuration and direction. Shoulders with a width of 12 feet or greater, ramps, tapers, turn slots, acceleration lanes and deceleration lanes will be profiled, but will not be subject to incentive adjustments. Shoulders with a width of 12 feet or more, ramps, tapers, turn slots, acceleration lanes and deceleration lanes will be evaluated for MRI and shall require corrective work if a 0.10 mile or fraction thereof section exceeds an MRI greater than 100.0 in/mile. The profile of the entire length of a lane shall be taken at one time. However, a lane profile may be broken into sections to accommodate project phasing. At the Pre -paving Conference, the Contractor shall submit a plan for breaking the project profiling into phases for approval by the Engineer. Shoulders less than 12 feet in width and medians will not be profiled and will not be subject to incentive adjustments. Shoulders less than 12 feet in width and medians constructed as part of the project shall be measured per subsection 105.07(a). Pavement 25 feet outside of a traffic circle and traffic circles will not be profiled and will not be subject to incentive adjustments. Traffic circles shall be measured per subsection 105.07(a). A sufficient distance shall be deleted from the profile to allow the profiler to obtain the testing speed, plus a 300 -foot distance to stop and start when required. The distance deleted from a profile shall be minimized by reducing testing speed as necessary. Incentive adjustments will not be made for this area. The final surface of these areas shall be tested per subsection 105.07(a). The profile shall include transverse joints when pavement is placed on both sides of the joint. When pavement is placed on only one side of the joint, the profile shall start and stop 25 feet outside project paving limits. The section of pavement 25 feet outside the paving limits to 5 feet inside the paving limits will be evaluated per subsection 105.07(a) and will not be subject to incentive adjustments. The profile of the area 25 feet each side of every expansion joint, railroad crossing, cattle guard, bus pad, manhole, gutter pan and intersection (where there is a planned Page 56 of 292 December 18, 2024 Revision of Section 105 — Control of Work breakpoint in the profile grade line in the direction of traffic) shall be deleted from the profile before the MRI is determined. Incentive adjustments will not be made for these areas. Areas deleted from the profile shall be tested per subsection 105.07(a). The profile of the area 25 feet each side of the bridge deck shall be deleted from the profile before the MRI is determined. Incentive adjustments will not be made for this area. When both pavement and a bridge or bridge pavement are being constructed on the project, areas deleted from the profile shall be tested per subsection 105.07(a). Corrective work required in these areas will not be measured and paid for separately but shall be included in the work. For all other projects, the profile of the area 25 feet each side of the bridge deck shall be deleted from the profile before the MRI is determined. If the Engineer determines that corrective work is required in this area, payment will be made per subsection 109.04. The Contractor shall notify the Engineer in writing at least five working days in advance of their intention to perform SA testing. The Contractor shall profile the project within 14 days after the completion of paving operations. The Department will determine if Smoothness Verification Testing (SV) will be performed. If SV testing will be performed, it will be performed at the same time as the SA testing. The Engineer will witness the SA profiling. Within 24 hours after each profile is collected, the Contractor shall submit the data electronically along with an SA data submittal form to the Engineer and Inspector. 2. Smoothness Testing Procedures. The Contractor shall mark the profiling limits and excluded areas. The Engineer will verify that the Contractor's marks are located properly. The Contractor shall use traffic cones with reflective tape or reflective tape on the pavement at the beginning and end of each lane for triggering the start and stop locations on the profiler and at any other location, where portions of the profile are being excluded. GPS triggering shall not be used. These locations shall be marked with temporary paint so that the final SA testing uses the same triggering locations. The ambient temperature shall be at least 34 °F for the profiler to operate. The Contractor shall clear the lanes to be tested of all debris before profiling. Each lane shall be profiled at least once. Profiling shall be at a constant speed (+/- 5 mph of the distance calibration speed) with a minimum speed of 15 mph and a maximum speed of 70 mph. Shoulders with a width of 12 feet or more, ramps, tapers, turn slots, acceleration lanes, and deceleration lanes shall be profiled once. The profile shall be taken in the planned direction of travel. The left and right wheel paths shall be profiled simultaneously. Triggers for the start of the profile, the end of the profile, and the locations of each exclusion shall be collected during each run. The collected profiles shall be electronically submitted to the Department and Engineer to be analyzed using CP 74. Page 57 of 292 December 18, 2024 Revision of Section 105 — Control of Work The Department will determine an MRI for each 0.1 -mile section or fraction thereof of completed pavement. Sections will terminate at the beginning of an exclusion and a new section starts at the end of exclusion. The MRI consists of the left and right wheel path's profile passed through the International Roughness Index (IRI) filter. The IRI for the left and right wheel paths are averaged to determine MRI. The Contractor's SA test results will be available within ten working days of the completion of SA testing. The Engineer will give the Contractor a report that will include the lane profiled, the MRI in 0.1 -mile increments, and a summary of areas requiring corrective work. Areas requiring corrective work shall be addressed per 105.07(e) and the entire length of the lane(s) identified with corrective work shall be re -profiled and re -submitted as outlined in this section. Sections less than 0.005 miles in length shall not be subject to corrective work as specified by Table 105-13. Sections less than 0.005 miles in length shall be evaluated per subsection 105.07(a). (c) MRI Category D: For MRI Category D pavements, the following shall be used for acceptance: An MRI for each 0.1 -mile section shall be determined on the original pavement surface prior to beginning the work in accordance with subsection 105.07(b) without exclusions. An MRI for each 0.1 -mile section shall be determined on the pavement surface after the work is complete in accordance with subsection 105.07(b) without exclusions. The original and final profile lengths shall have a difference in the length of each lane less than 0.2 percent. When the profile length difference exceeds 0.2 percent, the final testing shall be repeated. When a 0.1 -mile section has a final MRI greater than 92.0 inches/mile and the final MRI is greater than the MRI prior to performing the work, that 0.1 -mile section shall be corrected by a method approved in writing by the Engineer. Corrective work shall be such that the resulting final MRI is equal to or less than the initial MRI or 92.0 in/mile, whichever is greater. All costs associated with corrective work shall be at the Contractor's expense, including but not limited to traffic control, additional hot mix asphalt, grinding, and milling. When the Contractor fails to collect the profile of the original pavement surface prior to beginning the work, the final pavement surface will be evaluated for corrective work in accordance with the criteria for Category C pavement smoothness. Incentive adjustments for smoothness will not be made for MRI Category D. Pavements evaluated for MRI Category D that will be overlaid with a surface seal shall be evaluated for pavement smoothness prior to application of the surface seal (e.g., chip seal). Page 58 of 292 December 18, 2024 Revision of Section 105 - Control of Work (d) Acceptance and Incentive Adjustments. This Project does not have monetary incentive/disincentive payments associated with HMA or PCCP pavement smoothness. The Contractor shall still meet all requirements and conditions for the pavement smoothness category defined for the project. Final acceptance for pavement smoothness will be based on the MRI for each 0.1 -mile section or fraction thereof from the Contractor's initial SA testing. Those sections requiring corrective work indicated by the initial SA testing will be re-evaluated.

The Department will analyze the initial and final SA testing for acceptance and indicate areas requiring corrective work in accordance with subsection 105.07(b). The Engineer, at their sole discretion, shall determine the most effective corrective action outlined in items 1-3 below. The Contractor shall provide a detailed method statement describing the corrective actions to be taken for the corrective work. Corrective work shall not be performed until the method statement has been approved in writing by the Engineer. The Contractor shall perform corrective work in the areas indicated by the Department based on the SA testing. The criteria for determining if a 0.1 -mile section requires corrective work is specified in Table 105-11 or 105-12. The criteria for determining if a section less than 0.10 miles in length and greater than 0.005 miles in length requires corrective work is specified in Table 105-13. Shoulders with a width of 12 feet or more, ramps, tapers, turn slots, acceleration lanes and deceleration lanes will be evaluated for MRI and shall require corrective work if a 0.10 -mile section exceeds an MRI greater than 100.0 in/mile. Sections greater than 0.005 mile, but less than 0.1 miles shall not exceed MRI = 152.63 — 526.32 * D, where D is section length in miles. Corrective work shall consist of diamond grinding, an approved overlay, or removal and replacement. Corrective work shall conform to of one of the following conditions: 1. HMA Removal and Replacement. The pavement requiring corrective work shall be removed, full width of the lane and the full thickness of the layer per subsection 202.09. The removal area shall begin and end with a transverse butt joint, which shall be constructed with a transverse saw cut perpendicular to centerline. Replacement material shall be placed in sufficient quantity, so the finished surface conforms to grade and smoothness requirements. Sections removed and replaced shall be at least 0.20 miles in length. 2. HMA Overlay. The overlay shall cover the full width of the pavement including shoulders and adjacent lanes. The area overlaid shall begin and end with a transverse butt joint, which shall be constructed with a transverse saw cut and asphalt removal. All material shall be approved hot bituminous mixtures that meet all contract requirements. The overlay shall be placed so that the finished surface conforms to grade and smoothness requirements. The overlay area shall be compacted to the Page 60 of 292 December 18, 2024 Revision of Section 105 — Control of Work specified density. The overlay thickness shall be equivalent to that of the final layer per the Contract. Sections overlaid shall be at least 0.20 miles in length. 3. Diamond Grinding. Grinding shall be performed using diamond blades mounted on a self-propelled machine designed for grinding and texturing pavement. The equipment shall weigh a minimum 17,000 pounds including the grinding head and be of a size that will grind a strip at least 3 feet wide in a single pass. The effective wheelbase of the machine shall be at least 12 feet. Grinding equipment that causes raveling, aggregate fractures or disturbance to the joints shall not be permitted. The equipment shall be maintained to ensure it is in proper working order, including the roundness of the match and depth of control wheels. Any wheels found to be out of round shall be immediately replaced. The Engineer may approve smaller equipment for areas that the above equipment cannot reach. Grinding equipment that causes raveling, aggregate fractures or disturbance to the joints shall not be permitted. All grinding shall be parallel to the longitudinal joints. Adjacent passes shall be overlapped by a maximum of 2 inches. The grinding process shall produce a pavement surface that is true to grade and uniform in appearance. The grooves shall be evenly spaced. Any ridges on the outside edge next to the shoulder, auxiliary, or ramp lanes greater than 3/16 -inch high shall be feathered out to the satisfaction of the Engineer in a separate, feather pass operation. No adverse drainage conditions shall be caused by the grinding operations. Grinding shall not reduce planned pavement thickness by more than 0.3 inches. Diamond grinding shall be the full width of a wheel path. The wheel path is from the stripe to the center of the lane. The pavement surface after grinding shall have no depressions or misalignment of slope in the longitudinal direction exceeding 1/8 inch in 12 feet when measured with a 12 -foot straightedge placed parallel to the centerline. All areas of deviation shall be reground at no additional cost. The equipment shall have a positive means of vacuuming the grinding residue from the pavement surface, leaving the surface in a clean, near -dry condition. The slurry and residue resulting from the grinding operation shall not be allowed to flow across lanes occupied by the traffic and shall be continuously removed during the grinding operation, leaving the pavement in a clean condition. The Contractor shall haul the grinding residue to a suitable location at an approved location at no additional cost. Cores shall be taken to verify that minimum pavement thicknesses have been maintained. A minimum of one core shall be taken every 100 cumulative feet or fraction thereof per lane of diamond grinding, as directed by the Engineer. Coring shall be at the Contractor's expense. Page 61 of 292 December 18, 2024 Revision of Section 105 — Control of Work For HMA pavements, the entire ground area of the final pavement surface shall be covered with a Tack Coat conforming to Section 407 (CSS-lh at 0.1 gallons per square yard of diluted emulsion; the emulsion shall be diluted with water at the rate of 50 percent water and 50 percent emulsion) when grinding is complete after corrective work has been completed. The tack coat shall not be measured and paid for separately but shall be included in the Work. When any grinding on concrete pavement occurs where a core for determining pavement thickness has been previously taken, another core shall be taken after the grinding has been completed and shall replace the original core in the calculation of pavement thickness incentive and disincentive. Joint sealant that has been damaged by grinding on concrete pavement shall be repaired or replaced at the Contractor's expense in accordance with Standard Plan M-412-1 and subsection 412.18. For PCCP, diamond ground surface texture will be considered acceptable when the average texture depth (ATD) of the panel is greater than 0.05 inch. The Contractor will perform surface texture testing in accordance with CP 77 Method B. Each area in a lane that required diamond grinding will be tested at least once. Areas in a lane with more than 500 continuous feet of grinding will be tested at a frequency of one test per 500 linear feet. Areas with deficient surface texture shall be diamond ground and retested. Final Smoothness Acceptance Testing. After the Contractor has completed the required corrective work, the Contractor shall retest the pavement per subsection 105.07(b). Final SA testing shall only be required on lanes with sections requiring corrective work. Final SA testing shall start and stop at the same locations as the Initial SA testing. If additional corrective work is required, the Contractor shall perform the corrective work and perform additional Final SA Testing. Time count will be charged pursuant to contract requirements during the time period required for all Final SA. Delays associated with additional Final SA Testing will be considered non -excusable and non-compensable. The Contractor shall notify the Engineer by email at least 5 working days in advance of their intention to perform final SA testing. The Department will determine if Smoothness Verification Testing (SV) will be performed. If SV testing will be performed, it will be performed at the same time as the SA testing. The Initial SA and Final SA profile lengths shall have a difference in the length of each lane less than 0.2 percent. When the profile length difference exceeds 0.2 percent, the Final SA testing shall be repeated. Department Smoothness Verification Testing (SV). The Department may elect to perform smoothness verification testing using the Department's SV contractor's inertial profiler, with the methods described in subsection 105.07(b). The Engineer will notify the Contractor of the Department's intention to perform SV testing. The Contractor shall Page 62 of 292 December 18, 2024 Revision of Section 105 — Control of Work coordinate with the Department and his profiler to schedule SA and SV to occur at the same time. The Department will randomly select scheduled Contractor Smoothness Acceptance Testing to verify. A minimum of 25 percent of each scheduled Contractor Smoothness Acceptance Testing by an individual profiler will be verified. The Engineer may also request verification for any Smoothness Acceptance Testing. The Contractor's SA test results will be compared to the Department's SV test results. The Contractor's SA test results will be considered acceptable and will be used for incentive payment if the following criteria are met: 1. The difference in MRI for a 1/10 -mile section is less than 6.1 inches/mile for a minimum of 90 percent of the 1/10 -mile sections for each lane. 2. The difference in average MRI for each lane is less than 6.1 inches/mile. 3. The difference in the length of each lane is less than 0.2 percent. When the Contractor's SA test results are not considered acceptable, the Department's SV test results will be used for incentive payment and the Contractor's profiler certification will be suspended and evaluated pursuant to CP 78. The Contractor shall schedule with the Department within 10 working days to perform this evaluation or the profiler will be required to be re -certified per CP 78. Subsection 105.08 shall be deleted and replaced with the following: 105.08 Document Management and Professional Engineer and Professional Land Surveyor Electronic Seals. Where the specifications require the Contractor to submit or return documents either in writing or the format is not specified, an electronic file is preferred. The Contractor shall submit the schedule native file, video recordings, photographs, image files, and other media formats in their native file formats. When the document format is not specified, the contractor shall submit electronic documents in PDF. When a submittal requires multiple copies, one electronic document shall satisfy the requirement. Where a signature is needed, an electronic signature is acceptable. An original signature is a signature signed in ink. Where original signatures or original documents are required a scan shall satisfy the requirement. The Department will issue Contract Modification Orders (Form 90) and Form 105s that authorize additional work for signature via AdobeSign. Forms and records shall be signed with an electronic signature that includes the signer's name, date, and time the document was signed, in addition to locking the appropriate portions after signing. This guidance does not change the approval process or the content requirements for Page 63 of 292 December 18, 2024 Revision of Section 105 - Control of Work Buy America, COC, and CTR documentation, rather it allows the documentation to either be all electronically signed or a Scanned Original Wet Signature. An electronic seal is when a Contractor's Engineer, a Professional Engineer or a Professional Land Surveyor affix their electronic signature and seal to plans or documents prepared under their responsible charge or control. The electronic seal needs to meet State of Colorado Architects, Professional Engineers, and Professional Land Surveyors Rules and Regulations, 4 CCR 730-1 requirements, lock the document after signature and shall have a non -expiring transaction identification number that can be used to view the final locked and signed document online. The Contractor shall submit as -built plans using the template provided by the Engineer. Subsection 105.09 shall be deleted and replaced with the following: 105.09 Coordination of Plans, Specifications, Supplemental Specifications, and Special Provisions. These specifications, the supplemental specifications, the plans, special provisions, and all supplementary documents are essential parts of the Contract, and a requirement occurring in one is as binding as though occurring in all. They are intended to be complementary and to describe and provide for a complete work. In the event of a discrepancy, the order of precedence is as follows: (a) Contract Documents including Exhibits, Addenda, and Appendices (b) Special Provisions 1. Weld County Project Special Provisions 2. Weld County Conformed Standard Special Revisions to CDOT's 2023 Standard Specifications for Road and Bridge Construction 3. CDOT Project Special Provisions 4. CDOT Standard Special Provisions 5. CDOT Field Materials Manual (Latest Edition) (c) CDOT Standard Specifications (d) Plans 1. Detailed Plans 2. Standard Plans Page 64 of 292 December 18, 2024 Revision of Section 105 — Control of Work 3. Calculated dimensions will govern over scaled dimensions. (e) CDOT Construction Manual (Latest Edition) Where the Contract Documents, Project Special Provisions, or the CDOT Specifications contradict one another, the more stringent specification shall apply. Notwithstanding the foregoing, in the event of conflicting requirements involving any requirement within the Contract Documents, Project Special Provisions, or the CDOT Specifications, the County shall have the right to determine, in its sole discretion, which requirement(s) apply. The Contractor shall request the County's determination respecting the order of precedence among conflicting provisions promptly upon becoming aware of any such conflict. The Contractor shall not take advantage of any apparent error or omission in the Contract. Should it appear that the work to be done or any matter relative thereto is not sufficiently detailed or explained in the Contract Documents, the Contractor shall immediately notify the Project Manager in writing for further written explanations as may be necessary and shall conform to the explanation provided. The Contractor shall promptly notify the Project Manager of all errors which it may discover in the Contract Documents and shall obtain specific instructions in writing regarding any such error before proceeding with the work affected thereby. The Project Manager will make corrections and interpretations as necessary to fulfill the intent of the Contract. If the Contract Documents omit or mis-describe any details of any work which is necessary to carry out the intent of the Contract Documents, that are customarily performed under similar circumstances, the Contractor shall not be relieved from performing such omitted work or mis- described details of the work, and they shall be performed as if fully and correctly set forth and described in the Contract Documents, without entitlement to a change order except as specifically allowed. Subsection 105.10 shall be deleted and replaced with the following: 105.10 Cooperation by Contractor. The Contractor shall give the work the constant attention necessary to facilitate progress and shall cooperate with the Engineer, inspectors, and other contractors. The Contractor shall be responsible for providing agendas, attendance lists, and meeting minutes for all meetings including but not limited to weekly progress meetings, pre -construction meetings, pre -pour meetings, pre -pave meetings, pre -environmental meetings, etc. Sample meeting agendas are provided in CDOT's Construction Manual. The sample meeting agendas shall be modified as necessary to contain project specific information. The Contractor shall provide copies of the meeting agendas to the Engineer a minimum of 24 hours before the meeting for review. During the meeting, the Contractor shall lead the meeting, take attendance, and take meeting minutes. Meeting minutes shall be generated by the Contractor and shall be provided to the Engineer within 72 hours for review and acceptance. Page 65 of 292 December 18, 2024 Revision of Section 105 — Control of Work The Contractor shall have on the project, at all times that work is being performed, a competent P roject Manager and a Superintendent capable of reading and understanding the contract documents and experienced in the type of work being performed. The Project Manager and S uperintendent shall not be the same individual unless approved in writing by the Engineer. The P roject Manager and Superintendent will receive instructions from the Engineer and shall be authorized to act for the Contractor on the project and to execute orders or directions of the Engineer without delay. The Project Manager and Superintendent shall promptly supply, irrespective of the amount of work sublet, materials, equipment, tools, labor, and incidentals to complete the Contract. Failure to provide a full-time competent Project Manager and a Superintendent with the authorization to act for the Contractor on the project shall result in pay reductions as outlined in Section 108.12 being applied. Furthermore, failure to provide a full-time competent Project Manager and a Superintendent shall be grounds for suspension of the Project until such time as a full-time competent Project Manager and Superintendent is provided by the Contractor. The Engineer shall have the sole discretion of determining when/if to assess the payment deduction. The payment deduction shall be documented on a Form 105, Speed Memo. Contract time will continue in the event of a work suspension caused by lack of furnishing a full-time competent Project Manager and a Superintendent that is satisfactory to the County. When the County issues a Speed Memo (Form 105), Minor Contract Revision (Form 94), or a Change Modification Order (Form 90), the Contractor shall return a signed version of the form within 10 calendar days. Failure to provide the signed form(s) to the Engineer shall result in the assessment of pay reductions as outlined in Subsection 108.12. S ubsection 105.11, paragraph 4 shall be deleted and replaced with the following: If utility facilities or appurtenances are found that are neither identified in the Contract, nor revealed by site investigation, the Engineer will determine whether adjustment or relocation of the utility is necessary. The Engineer will make arrangements with either the utility owner or the Contractor to accomplish necessary adjustments or relocations when not otherwise provided for in the Contract. Per subsection 104.02(a)(5, 7, 8, and 9), the discovery of unknown utility facilities or appurtenances shall not be entitled to a Change Order for Differing Site Conditions. Extra work may be considered for payment per subsection 104.03 only with the written approval of the Engineer. Consideration for additional contract time will be considered by the Engineer on a case -by -case basis. S ubsection 105.12, paragraph 1 shall be deleted and replaced with the following: The Contractor shall be responsible for managing all subcontractors, subcontractors of a subcontractor, all subsequent tiers. Failure to manage the subcontractors shall result in a stoppage of work and the assessment of liquidated damages in accordance with Section 108.09 of these Specifications, at the discretion of the Engineer. Working time shall not cease but shall continue. No additional time will be granted for a stoppage of work. If the Contractor fails to meet the specified completion date or milestone date, additional liquidated damages will apply. Page 66 of 292 December 18, 2024 Revision of Section 105 - Control of Work S ubsection 105.21(b) shall be deleted and replaced with the following: (b) Final Acceptance. At Substantial Completion, the Engineer will make an inspection of the project with the Contractor. The result of the inspection will be a punch list of outstanding items that have to be corrected and completed withing the time frame indicated on the Notice of Substantial Completion. The punchlist will include the remaining documentation items that shall be submitted for review and acceptance by the Engineer prior to Final Acceptance. Upon notice from the Contractor of completion of the Substantial Completion punchlist, the Engineer will make an inspection to verify the punchlist items have been addressed. If the work provided for by the Contract has been satisfactorily completed, that inspection shall constitute the final inspection and the Engineer will notify the Contractor in writing of final acceptance indicating the date on which the project was inspected and accepted. Upon reviewing and accepting the remaining documentation and with no other outstanding issues, the Engineer will initiate the final advertisement process utilized by the County's Purchasing Department. The final advertisement process involves placing an advertisement in a newspaper of general circulation a minimum of two times at least 10 days apart. A newspaper of general circulation is defined as a newspaper which is published daily, triweekly, semiweekly, or weekly and is printed or published in whole or in part in the county in which such notice or advertisement is required to be published. The advertisement shall include the final cutoff date for any protests from subcontractors or suppliers and the date of anticipated final payment to the Contractor. No retainage release will be made until the final advertisement period has been completed and all issues that have arisen during the final advertisement period have been resolved. Final acceptance under this subsection does not waive any legal rights contained in subsection 107.21. Subsection 105.22 shall be amended as follows: Delete all references to CDOT and replace with Weld County. S ubsection 105.22, paragraph 1 shall be deleted and replaced with the following: 105.22 Dispute Resolution. CDOT shall not participate in the resolution process for any claims filed by the Contractor. Weld County shall be the responsible party to such claims. Subsections 105.22, 105.23, and 105.24 detail the process through which the parties (Weld County and the Contractor) agree to resolve any issue that may result in a dispute. The intent of the process is to resolve issues early, efficiently, and as close to the project level as possible. Figure 105-1 outlines the process. Specified time frames may be extended by mutual agreement of the Engineer and the Contractor. In these subsections, when a time frame ends on a Saturday, S unday or holiday, the time frame shall be extended to the next scheduled workday. Page 67 of 292 December 18, 2024 Revision of Section 105 - Control of Work S ubsection 105.22(c) shall be deleted and replaced with the following: (c) Project Engineer Review. Within 15 days after receipt of the REA, the Project Engineer will meet with the Contractor to discuss the merits of the dispute. Within seven days after this meeting, the Project Engineer will issue a written decision on the merits of the dispute. The Project Engineer will either deny the merits of the dispute or notify the Contractor that the dispute has merit. This determination will include a summary of the relevant facts, Contract provisions supporting the determination, and an evaluation of all scheduling issues that may be involved. If the dispute is determined to have merit, the Contractor and the Project Engineer will determine the adjustment in payment, schedule, or both within 30 days. When a satisfactory adjustment is determined, it shall be implemented per subsections 106.05, 108.08, 109.04, 109.05 or 109.10 and the dispute is resolved. If the Contractor accepts the Project Engineer's denial of the merits of the dispute, the dispute is resolved, and no further action will be taken. If the Contractor does not respond in seven days, it will be assumed the Contractor has accepted the denial. If the Contractor rejects the Project Engineer's denial of the merits of the dispute or a satisfactory adjustment of payment or schedule cannot be agreed upon within 30 days, the Contractor may further pursue resolution of the dispute by presenting the dispute to the Dispute Review Board per subsection 105.23. S ubsection 105.23 shall be amended as follows: Delete all references to CDOT and replace with Weld County. S ubsection 105.23(b)(1) shall be deleted and replaced with the following: CDOT in conjunction with the Colorado Contractors Association, maintains a statewide list of pre -approved DRB candidates experienced in construction processes and the interpretation of contract documents and the resolution of construction disputes. Weld County will utilize this list during the DRB process. Only individuals who have completed training (currently titled DRB Administration and Practice Training) through the Dispute Resolution Board Foundation or otherwise approved by Weld County can be a DRB member. DRB nominees shall be selected from the list of pre -approved candidates. When a DRB is formed, the parties shall execute the agreement set forth in subsection 105.23(1). S ubsection 105.23(i) shall be deleted and replaced with the following: Dispute Review Board Recommendation. The DRB shall issue a Recommendation per the following procedures: 1. The DRB shall not make a recommendation on the dispute at the meeting. Before the closure of the hearing, the DRB members and the Contractor and Weld County Page 68 of 292 December 18, 2024 Revision of Section 105 — Control of Work together will discuss the time needed for analysis and review of the dispute and the issuance of the DRB's recommendation. The maximum time shall be 30 days unless otherwise agreed to by both parties. 2. After the meeting has been closed, the DRB shall prepare a written Recommendation signed by each member of the DRB. In the case of a three member DRB where one member dissents, that member shall prepare a written dissent and sign it. The DRB's recommendation shall include the following: A. A summary of the issues and factual evidence presented by the Contractor and Weld County concerning the dispute. B. Recommendations concerning the validity of the dispute. C. Recommendations concerning the value of the dispute as to cost impacts if the dispute is determined to be valid. D. The contractual and factual bases supporting the recommendation(s) made including an explanation as to why each and every position was accepted or rejected. E. Detailed and supportable calculations which support any recommendation(s). 3. The chairperson shall transmit the signed Recommendation and any supporting documents to both parties. Subsection 105.24 shall be deleted and replaced with the following: 105.24 Claims for Unresolved Disputes. The Contractor may file a claim only if the disputes resolution process described in subsections 105.22 and 105.23 has been exhausted without resolution of the dispute. Other methods of nonbinding dispute resolution, exclusive of litigation, can be used if agreed to by both parties. This subsection applies to any unresolved dispute or set of disputes between Weld County and the Contractor with an aggregate value of more than $15,000. Unresolved disputes with an aggregate value of more than $15,000 from subcontractors, materials suppliers or any other entity not a party to the Contract shall be submitted through the Contractor per this subsection as a pass -through claim. Review of a pass -through claim does not create privity of Contract between Weld County and any other entity. Subsections 105.22, 105.23 and 105.24 provide both contractual alternative dispute resolution processes and constitute remedy -granting provisions pursuant to Colorado Revised Statutes (CRS) which must be exhausted in their entirety. Litigation proceedings must commence within 180 -calendar days of the Chief Engineer's decision, absent written agreement otherwise by both parties. Page 69 of 292 December 18, 2024 Revision of Section 105 — Control of Work The venue for all unresolved disputes with an aggregate value $15,000 or less shall be the County Court for Weld County. Non -binding Forms of alternative dispute resolution such as Mediation are available upon mutual agreement of the parties for all claims submitted per this subsection. The cost of the non -binding ADR process shall be shared equally by both parties with each party bearing its own preparation costs. The type of nonbinding ADR process shall be agreed upon by the parties and shall be conducted within the State of Colorado at a mutually acceptable location. Participation in a nonbinding ADR process does not in any way waive the requirement that litigation proceedings must commence within 180 -calendar days of the Chief Engineer's decision, absent written agreement otherwise by both parties. (a) Notice of Intent to File a Claim. Within 30 days after rejection of the Dispute Resolution Board's Recommendation issued per subsection 105.23, the Contractor shall provide the Director of Public Works (Director) or the Director's designated representative with a written notice of intent to file a claim. The Contractor shall also send a copy of this notice to the Engineer. Weld County will acknowledge in writing receipt of Notice of Intent within seven days. (b) Claim Package Submission.

All claims shall be in writing and in sufficient detail to enable the Director to ascertain the basis and amount of claim. The claim package shall include all documents supporting the claim, regardless of whether such documents were provided previously to Weld County. If requested by the Contractor, the 60 -day period may be extended by the Director in writing before final acceptance. At a minimum, the following information shall accompany each claim: 1. A claim certification containing the following language, as appropriate: A.

When the Contractor properly files a claim, the County Engineer will review the claim and render a written decision to the Contractor to either affirm or deny the claim, in whole or in part, per the following procedure. The County Engineer may consolidate all related claims on a project and issue one decision, provided that consolidation does not extend the time period within which the Director is to render a decision. Consolidation of unrelated claims will not be made. The County Engineer will render a written decision to the Contractor within 90 days after the receipt of the claim package or receipt of the audit whichever is later. In rendering the decision, the Director: (1) will review the information in the Contractor's claim; (2) will conduct a hearing if requested by either party; and (3) may consider any other information available in rendering a decision. Page 74 of 292 December 18, 2024 Revision of Section 105 — Control of Work The County Engineer will assemble and maintain a claim record comprised of all information physically submitted by the Contractor in support of the claim and all other discoverable information considered by the County Engineer in reaching a decision. Once the County Engineer assembles the claim record, the submission and consideration of additional information, other than for clarification and data supporting previously submitted documentation, at any subsequent level of review by anyone, will not be permitted. The County Engineer will provide a copy of the claim record and the written decision to the Contractor describing the information considered by the County in reaching a decision and the basis for that decision. If the County Engineer fails to render a written decision within the 60 -day period, or within any extended time period as agreed to by both parties, the Contractor shall either: (1) accept this as a denial of the claim, or (2) appeal the claim to the Director, as described in this subsection. If the Contractor accepts the County Engineer's decision, the provisions of the decision shall be implemented per subsections 108.08, 109.04, 109.05, or 109.10 and the claim is resolved. If the Contractor disagrees with the County Engineer's decision, the Contractor shall either: (1) accept the County Engineer's decision as final, or (2) file a written appeal to the Director within 30 days from the receipt of the County Engineer's decision. The Contractor hereby agrees that if a written appeal is not properly filed, the County Engineer's decision is final. (d) Director's (Chief Engineer) Decision. When a claim is appealed, the County Engineer will provide the claim record to the Director. Within 15 days of the appeal either party may submit a written request for a hearing with the Director or duly authorized delegate. The Director or duly authorized delegate will review the claim and render a decision to affirm, overrule, or modify the County Engineer's decision per the following: The Director will render a written decision within 60 days after receiving the written appeal. The Director will not consider any information that was not previously made a part of the claim record, other than clarification and data supporting previously submitted documentation. The Contractor shall have 30 days to accept or reject the Director's decision. The Contractor shall notify the Director of its acceptance or rejection in writing. If the Contractor accepts the Director's decision, the provisions of the decision will be implemented per subsections 108.08, 109.04, 109.05, or 109.10 and the claim is resolved. Page 75 of 292 December 18, 2024 Revision of Section 105 — Control of Work If the Contractor disagrees with the Director's decision, the Contractor shall either: (1) pursue an alternative dispute resolution process per this specification, or (2) initiate litigation or merit binding arbitration per subsection 105.24(f). If the Director does not issue a decision as required, the Contractor may immediately initiate either litigation or merit binding arbitration per subsection 105.24(f). For the convenience of the parties to the Contract it is mutually agreed by the parties that any merit binding arbitration or De Novo litigation shall be brought within 180 -calendar days from the date of the Director's decision. The parties understand and agree that the Contractor's failure to bring suit within the time period provided, shall be a complete bar to any such claims or causes of action. (e) De Novo Litigation or Merit Binding Arbitration. If the Contractor disagrees with the Director's decision, the Contractor may initiate de novo litigation or non -binding arbitration to finally resolve the claim that the Contractor submitted to Weld County. Such litigation or arbitration shall be strictly limited to those claims that were previously submitted and decided in the contractual dispute and claims processes outlined. This does not preclude the joining in one litigation or arbitration of multiple claims from the same project provided that each claim has gone through the dispute and claim process specified in subsections 105.22 through 105.24. The parties may agree, in writing, at any time, to pursue some other form of alternative dispute resolution. Any offer made by the Contractor or Weld County at any stage of the claims process, as set forth in this subsection, shall be deemed an offer of settlement pursuant to Colorado Rule of Evidence 408 and therefore inadmissible in any litigation or arbitration. If the Contractor selected litigation, then de novo litigation shall proceed per the Colorado Rules of Civil Procedure and the proper venue is the Colorado State District Court in and for Weld County, unless both parties agree to the use of arbitration. If the Contractor selected non -binding arbitration, or if both parties subsequently agreed to merit binding arbitration, arbitration shall be governed by the modified version of ARBITRATION PROVIDER'S Construction Industry Arbitration Rules which follow. Pursuant to the modified arbitration rules (R35 through R39), the arbitrators shall issue a decision with regard to entitlement and a non -binding decision with regard to quantum. If either party disagrees with the decision on quantum, the disagreeing party may seek a trial de novo in Weld County District Court with regard to quantum only.

When alternative materials are permitted for an item in the Contract, the Contractor shall state at the Pre -construction Conference the material that will be furnished for that item. Reference in the Contract to a particular product or to the product of a specific manufacturer, followed by the phrase "or approved equal", is intended only to establish a standard of quality, durability, and design, and shall not be construed as limiting competition. Products of other manufacturers will be acceptable provided such products are equal to that specified. In order to be considered an equal or equivalent product, all technical specifications for the alternate product must meet or exceed all technical specifications for the specified product. The technical specifications for the proposed equivalent product as well as the specified product shall be submitted to the Engineer for review. All rental equipment companies and all entities who meet the Supplier definition, as outlined in 101.02, in which the written agreement exceeds $10,000, shall have the following requirements for the Contract: (a) Rental equipment companies and Suppliers shall create an account in the B2GNow software system.

The Contractor shall develop a process control plan (PCP) per the following: 1. Process Control Plan. For each element listed in Table 106-2, the PCP must provide adequate details to ensure that the Contractor will perform process control. The Contractor shall submit the PCP to the Engineer at the Pre -construction Conference. The Contractor shall not start any work on the project until the Engineer has approved the PCP in writing. A. Frequency of Tests or Measurements. The PCP shall indicate a random sampling frequency, which shall not be less than that shown in Table 106-2. The process control tests shall be independent of acceptance tests. Table 106-2 — Schedule for Minimum Sampling and Testing for HMA Element Process Control Acceptance1'2 Check (CTP) Asphalt Content 1/500 tons 1/1,000 tons 1/10,000 tons Gradation 1/Day 1/2,000 tons 1/20,000 tons Theoretical Specific Maximum Gravity minimum 1/1,000 tons, 1/Day minimum 1/1000 tons, 1/Day 1/10,000 tons In -place Density 1/500 tons 1/500 tons 1/5,000 tons Joint Density 1 core/2,500 feet of joint linear linear 1 core/5,000 feet of joint 1 core/50,000 joint linear feet of Aggregate Moisture Percent 3 minimum 1/2,000 tons, 1/Day 1/2,000 tons Not applicable Percent Lime 3'4 1/Day Not applicable Not applicable Table Notes: 1 The minimum number of acceptance tests will be: 5 asphalt content, 3 gradation, 10 in -place density and 5 joint density for all projects. 2 When unscheduled job mix formula changes are made (Form 43) acceptance of the elements, except for in -place density, will be based on the actual number of samples that have been selected up to that time, even if the number is below the minimum listed in the schedule. At the Engineer's discretion, additional random in -place density tests may be taken in order to meet scheduled minimums, provided the applicable pavement layer is available for testing under safe conditions. Beginning with the new job mix formula, the quantity it will represent shall be estimated. A revised schedule of acceptance tests will be based on that estimate. 3 Not to be used for incentive or disincentive pay. Test according to CP-33 and report results from Form 106 or Form 565 on Form 6. 4 Verified per Contractor's PC Plan Page 86 of 292 December 18, 2024 Revision of Section 106 — Control of Material B. Worksheets, Forms, and Charts. The Contractor shall submit examples of worksheets, test result forms, and test results charts per CP 12 as part of the PCP. C. Test Result Chart. Each process control test result, the appropriate tonnage and the tolerance limits shall be plotted. For in place density tests, only results after final compaction shall be shown. The chart shall be posted daily at a location convenient for viewing by the Engineer. D. Quality Level Chart. The Quality Level (QL) for each element used to calculate incentive or disincentive in Table 106-2 and each required sieve size shall be plotted. The QL will be calculated per the procedure in CP 71 for Determining Quality Level (QL). The QL will be calculated on tests 1 through 3, then tests 1 through 4, then tests 1 through 5, then thereafter the last five consecutive test results. The tonnage of material represented by the last test result shall correspond to the QL. For in place density tests, only results after final compaction shall be shown. The chart shall be posted daily at a location convenient for viewing by the Engineer. 2. Elements Not Conforming to Process Control. The QL of each discrete group of five test results, beginning with the first group of five test results, shall be a standard for evaluating material not conforming to process control. When the group QL is below 65, the process shall be considered as not conforming to the PCP. In this case, the Contractor shall take immediate action to bring the process back into control. Except where the cause of the problem is readily apparent and corrected without delay, production shall be suspended until the source of the problem is determined and corrected. A written explanation of actions taken to correct control problems shall accompany the test data and be submitted to the Engineer on the day the actions are taken. 3. Point of Sampling. The material for process control testing shall be sampled by the Contractor using approved procedures. Acceptable procedures are Colorado Procedures, AASHTO, and ASTM. The order of precedence is Colorado Procedures, AASHTO procedures, and then ASTM procedures. The location where material samples will be taken shall be indicated in the PCP. 4. Testing Standards. Acceptable procedures are Colorado Procedures, AASHTO, and ASTM. The order of precedence is Colorado Procedures, AASHTO procedures, and then ASTM procedures. 5. Testing Supervisor Qualifications. The person responsible for the process control sampling and testing shall be identified in the PCP and be qualified according to the requirements of CP 10. 6. Technician Qualifications. Technicians taking samples and performing tests must be qualified according to the requirements of CP 10. Page 87 of 292 December 18, 2024 Revision of Section 106 — Control of Material 7. Testing Equipment. All of the testing equipment used to conduct process control testing shall conform to the standards specified in the test procedures and be in good working order. Nuclear testing devices used for process control testing of in -place density do not have to be calibrated on the Department's calibration blocks. 8. Reporting and Record Keeping. The Contractor shall report the results of the process control tests to the Engineer in writing at least once per day. The Contractor shall assemble a process control (PC) notebook and update it daily. This notebook shall contain all worksheets, test results forms, test results charts and quality level charts for each of the elements listed in Table 106-2. The Contractor shall submit the PC n otebook to the Engineer for review once a month on the date agreed to at the Pre - Paving Conference. The PC notebook will be returned to the Contractor within one working day after submittal. The Engineer will notify the Contractor in writing of any deficiencies in the PC notebook, including the failure to submit the notebook on time or an absence of the required reports. Upon the second failure to submit the complete PC notebook on time or with an absence of the required reports, the Engineer will n otify the Contractor, and the pay estimate will be withheld until the Contractor submits, in writing, a report detailing the cause for the failure to submit the complete PC notebook on time or the cause for the absence of required reports. The report shall include how the Contractor plans to resolve the failures. Additional failures to submit the PC notebook on time or absent the required reports will result in a delay of the pay estimate until the Contractor has identified and resolved the failure along with revising and resubmitting his PCP to address these issues. Once the Engineer has reviewed and approved the revised PCP the estimate may be paid. Upon submittal of the PC notebook for the semi-final estimate, the PC notebook shall become the property of the Department. The Contractor shall make provisions such that the Engineer can inspect process control work in progress, including PC n otebook, sampling, testing, plants, and the Contractor's testing facilities at any time. After compaction of the HMA is completed, in -place density tests for process control shall be taken at the frequency shown in Table 106-2. The results shall be reported in writing to the Engineer on a daily basis. Daily plots of the test results with tonnage represented shall be made on a chart convenient for viewing by the Engineer. All of the testing equipment used for in -place density testing shall conform to the requirements of acceptance testing standards, except nuclear testing devices need n ot be calibrated on the Department's calibration blocks. (b) Acceptance Testing. Acceptance testing is the responsibility of the Department and shall not be addressed in the PCP. The Department will determine the locations where samples or measurements are to be taken. The maximum quantity of material represented by each test result, the elements, the frequency of testing and the minimum number of test results will be per Table 106-2. The location or time of sampling will be based on the stratified random procedure as described in CP 75. Acceptance sampling and testing procedures will be per the Schedule for Minimum Materials Sampling, Testing and Inspection in the Page 88 of 292 December 18, 2024 Revision of Section 106 - Control of Material CDOT Field Materials Manual. Samples for project acceptance testing shall be taken by the Contractor per the designated method. The samples shall be taken in the presence of the Engineer. Where appropriate, the Contractor shall reduce each sample to the size designated by the Engineer. The Contractor may retain a split of each sample which cannot be included as part of the Contractor's process control testing. If the Contractor elects to question the Hot Mix Asphalt (HMA) acceptance test results, the steps outlined in CP 17 shall be followed. Dispute of the acceptance test results per CP- 17 will not be allowed unless the CP-13 Check Test Program has been successfully completed. The Contractor shall initiate, coordinate, and complete a successful Check Testing Program with the OA tester before HMA placement. The results from the CP 17 resolution process shall be binding on both the Department and the Contractor. Requests for CP 17 process for all elements except density shall be submitted in writing to the Engineer within five workdays from the date the Contractor receives acceptance test data from the Engineer. The specific element questioned shall be identified in writing. All requests for the CP 17 process for the density element shall be submitted in writing to the Engineer within 24 hours of receiving test data from the Engineer. The Contractor shall choose a consultant laboratory not associated with the project from the CDOT pre -established list to perform the third -party testing. The Contractor shall document his choice in writing at the Pre -Paving Conference. The Department shall determine that the consultant has no conflict of interest. If third party testing is required, the responsibility for the testing expenses shall be assigned per CP 17. The costs for testing are shown in CP 17, Table 17-2. All materials being used are subject to inspection and testing at any time before, during, or after incorporation into work. Acceptance tests will be made by and at the expense of the Department except when otherwise provided. (c) Check Testing Program (CTP). Before, or in conjunction with, placing the first 500 tons of asphalt pavement, under the direction of the Engineer, a CTP will be conducted between acceptance testing and process control testing programs. The CTP will consist of testing for asphalt content, theoretical maximum specific gravity, HMA 4.75 mm (#4) sieve, HMA 2.36 mm (#8) sieve, HMA 0.075 mm (#200) sieve, in -place density, and joint density per CP 13. An additional set of split samples from this CTP shall be retained and used in the event of third party testing per CP 17. If the Contractor intends to test to determine air voids and VMA, check testing for these tests is recommended. The CTP will be continued until the acceptance and process control tests are within the acceptable limits shown in Table 13-1 of CP 13. For joint density, the initial check test will be a comparison of the seven cores tested by CDOT and the seven cores tested by the Contractor. These are the cores from the compaction test section used for nuclear gauge calibration and test section payment. During production, a split sample check will be conducted at the frequency shown in Table 106-2. Except for joint density, the split samples will be from an acceptance sample Page 89 of 292 December 18, 2024 Revision of Section 106 — Control of Material obtained per subsection 106.05(b). The acceptance test result will be compared to the process control test result obtained by the Contractor using the acceptable limits shown in Table 13-1 of CP 13. For joint density, the comparison sample for testing by the Contractor will be obtained by taking a second core adjacent to the joint density acceptance core. The acceptance test result will be compared to the process control test result obtained by the Contractor using the acceptable limits as shown in Table 13-1 of CP 13 and following the check testing procedure given in CP 13. If production has been suspended and then resumed, the Engineer may order a CTP between process control and acceptance testing persons to assure the test results are within the acceptable limits shown in Table 13-1 of CP 13. Check test results shall not be included in process control testing. The Engineer shall be called upon to resolve differences if a CTP shows unresolved differences beyond the values shown in Table 13- 1 of CP 13. (d) Stability Verification Testing. After the mix design has been approved and production commences, the Department will perform a minimum of three stability verification tests to verify that the field produced HMA conforms to the approved mix design: The test frequency shall be one per day unless otherwise directed by the Engineer. The test results will be evaluated, and the Contractor shall make adjustments if required per the following: 1. The minimum value for stability will be the minimum specified in Table 403-1 of the specifications. There will be no tolerance limit. 2. Quality Level. Calculate a QL for stability. If the QL for stability is less than 65, then production shall be halted, and the Contractor shall submit a written proposal for a mix design revision to the Engineer. The Engineer shall give written approval to the proposed mix design revision before production continues. After a new or revised mix design is approved, three additional stability tests will be performed on asphalt produced with the new or revised mix design. The test frequency shall be one per day unless altered by the Engineer. If the stability QL is less than 65, then production shall be halted until a new mix design has been completed and approved using plant produced material or the Contractor shall submit a written proposal for a mix design revision to the Engineer. The Engineer shall give written approval to the proposed mix design revision before production continues. 3. New or Revised Mix Design. Whenever a new or revised mix design is used and production resumes, three additional stability field verification tests shall be performed, Page 90 of 292 December 18, 2024 Revision of Section 106 — Control of Material and the test results evaluated per the above requirements. The test frequency shall be one per day unless altered by the Engineer. 4. Field Verification Process Complete. When the field verification process described above is complete and production continues, the sample frequency will revert back to 1 per 10,000 tons. (e) Mix Verification Testing. After the mix design has been approved and production commences, the Department will perform a minimum of three volumetric verification tests for each of the following elements to verify that the field produced hot mix asphalt conforms to the approved mix design: 1. Air Voids 2. Voids in Mineral Aggregate (VMA). 3. Asphalt Content (AC). The test frequency shall be one per day unless altered by the Engineer. The test results will be evaluated, and the Contractor shall make adjustments if required per the following: 1. Target Values. The target value for VMA will be the average of the first three volumetric field test results on project produced hot mix asphalt or the target value specified in Table 403-1 and Table 403-2 of the specifications, whichever is higher. The target value for VMA will be set no lower than 0.5 percent below the VMA target on Form 43 before production. The target values for the test element of air voids and AC shall be the mix design air voids and mix design AC as shown on Form 43. 2. Tolerance Limits. The tolerance limits for each test element shall be: AC ± 0.3 percent Air Voids ± 1.2 percent VMA ± 1.2 percent 3. Quality Levels. Calculate an individual QL for each of the elements using the volumetric field verification test results. If the QL for VMA or AC is less than 65 or if the QL for air voids is less than 70, the production shall be halted, and the Contractor shall submit a written proposal for a mix design revision to the Engineer. Production shall only commence upon receipt of written approval from the Engineer of the proposed mix design revision. Page 91 of 292 December 18, 2024 Revision of Section 106 — Control of Material After a new or revised mix design is approved, three additional volumetric field verification tests will be performed on asphalt produced with the new or revised mix design. The test frequency shall be one per day unless altered by the Engineer. If the QL for VMA or AC is less than 65 or the QL for the test element of air voids is less than 70, then production shall be halted until a new mix design has been completed per CP 52 or CP 54, a new Form 43 issued, and the Contractor demonstrates that he is capable of producing a mixture meeting the verification requirements per A or B below: A. The Contractor shall produce test material at a site other than a Weld County project. The Contractor shall notify the Engineer a minimum of 48 hours before the requested test. The location and time of the test are subject to the approval of the Engineer before placement. Three samples will be tested for volumetric properties. If the QL for VMA or AC is equal or greater than 65 and the QL for the element of air voids is equal or greater than 70, full production may resume or; B. The Contractor may construct a 500 ton test strip on the project. Three samples in the last 200 tons will be tested for volumetric properties. After construction of the test section, production shall be halted until the testing is complete and element QLs are calculated. If the QL for VMA or AC is equal or greater than 65 or the QL for the element of air voids is equal or greater than 70, full production may resume. If the QL for VMA or AC is less than 65 or the QL for the element of air voids is less than 70, the material shall be removed and replaced at no cost to the Department. The time count will continue, and any delay to the project will be considered to have been caused by the Contractor and will not be compensable. The costs associated with mix designs shall be solely at the Contractor's expense. If the Contractor fails to verify the new mix design per A or B, then production shall be halted until a new mix design has been completed per CP 52 or CP 54, a new Form 43 issued, and the Contractor demonstrates they are capable of producing a mixture meeting the verification requirements per A or B. 4. New or Revised Mix Design. Whenever a new or revised mix design is used and production resumes, three additional volumetric field verification tests shall be performed, and the test results evaluated per the above requirements. The test frequency shall be one per day unless altered by the Engineer. 5. Field Verification Process Complete. When the field verification process described above is complete and production continues, the sample frequency will revert back to a minimum of 1/10,000 tons. The Engineer has the discretion to conduct additional verification tests at any time. Page 92 of 292 December 18, 2024 Revision of Section 106 - Control of Material (f) Testing Schedule. Process control and project acceptance testing frequency shall be per Table 106-2. (g) Reference Conditions. Three reference conditions can exist determined by the Moving Quality Level (MQL). The MQL will be calculated per the procedure in CP 71 for Determining Quality Level (QL). The MQL will be calculated using only acceptance tests. The MQL will be calculated on tests 1 through 3, then tests 1 through 4, then tests 1 through 5, then thereafter on the last five consecutive test results. The MQL will not be used to determine pay factors. The three reference conditions and actions that will be taken are described as follows: (1) Condition green will exist for an element when an MQL of 90 or greater is reached, or maintained, and the past five consecutive test results are within the specification limits. (2) Condition yellow will exist for all elements at the beginning of production or when a new process is established because of changes in materials or the job -mix formula, following an extended suspension of work, or when the MQL is less than 90 and equal to or greater than 65. Once an element is at condition green, if the MQL falls below 90 or a test result falls outside the specification limits, the condition will revert to yellow or red as appropriate. (3) Condition red will exist for any element when the MQL is less than 65. The Contractor shall be notified immediately in writing and the process control sampling and testing frequency increased to a minimum rate of 1/250 tons for that element. The process control sampling and testing frequency shall remain at 1/250 tons until the process control QL reaches or exceeds 78. If the QL for the next five process control tests is below 65, production will be suspended. If gradation is the element with MQL less than 65, the Department will test one randomly selected sample in the first 1250 tons produced in condition red. If this test result is outside the tolerance limits, production will be suspended. (This test result will not be included as an acceptance test.) After condition red exists, a new MQL will be started. Acceptance testing will stay at the frequency shown in Table 106-2. After three acceptance tests, if the MQL is less than 65, production will be suspended. Production will remain suspended until the source of the problem is identified and corrected. Each time production is suspended, corrective actions shall be proposed in writing by the Contractor and approved in writing by the Engineer before production may resume. Upon resuming production, the process control sampling and testing frequency for the elements causing the condition red shall remain at 1/250 tons. If the QL for the next five process control tests is below 65, production will be suspended again. If gradation is the element with MQL less than 65, the Department will test one randomly selected Page 93 of 292 December 18, 2024 Revision of Section 106 — Control of Material sample in the first 1250 tons produced in condition red. If this test result is outside the tolerance limits, production will be suspended. Subsection 106.051 shall be inserted immediately after Subsection 106.05 and shall include the following: 106.051 Sampling and Testing of Hot Mix Asphalt (Less than 5,000 tons). All hot mix asphalt, Item 403, except Hot Mix Asphalt (Patching) and temporary pavement shall be tested per the following program of process control testing and acceptance testing: OA sampling frequencies shall follow Table 106-3 and Stratified Random Sampling Schedules. Although Incentive/Disincentive payments may not be made to the Contractor for Hot Mix Asphalt, the conformance to contract of the material and elements involved shall be evaluated using the (Asphalt 03') Quality Project Management program and Sections 105.03. Dispute of the OA acceptance test results per CP-17 shall not be allowed unless Check Testing per CP-13 has been successfully completed for the elements specified. The Contractor shall initiate, coordinate, and complete a successful Check Testing Program with OA before hot mix asphalt placement. Hot Mix Asphalt Mix Designs submitted shall have historical test data on Total Voids %, VMA and AC Content %. If none are available, the Department may perform Verification for these elements on first day of production or if other element test results indicate a conformance issue. OA acceptance testing of the Mat Density element, shall follow Table 106-3 Note #1 using Asphalt Core samples tested per CP 44 (7-19), Method B. A Compaction Test Section or Gauge Correlation shall not be required by the Department. If PC performs gauge correlations, coring shall be the responsibility of the Contractor as is the repair of the core holes. Reduction in testing and sampling may be considered for specific testing elements or in whole if tonnage warrants. This in no way relieves the Contractor of submitting and executing approved construction method statements, quality control plans or placement of specification materials. For this project, Contractor process control testing of hot mix asphalt is mandatory and shall be accomplished every day that any HMA placement occurs on the jobsite. Process control testing will include Table 106-3 as stated below. (a) Process Control Testing. The Contractor shall be responsible for process control testing on all elements and at the frequency listed in Table 106-3. Process control testing for HMA pay items shall not be measured and paid for separately but shall be included in the work. The Contractor's HMA supplier and HMA paving subcontractor shall be present when HMA paving is occurring and shall test the HMA in accordance with Table 106-3. Page 94 of 292 December 18, 2024 Revision of Section 106 - Control of Material Table 106-3 - Schedule for Minimum Sampling and Testing for HMA Element Process Control Owner Acceptance (1) Asphalt Content 1/500 tons 1/1,000 tons Theoretical Specific Maximum Gravity1/day 1/1,000 tons, minimum 1/day 1/1,000 tons, minimum Gradation 2 1/Day 1/2,000 tons In -Place Density 1/500 tons 1/500 tons Joint Density 1 core/2,500 linear feet of joint 1 core /5,000 of joint linear feet Aggregate Moisture Percent 3 1/2,000 tons or 2,000 1/Day tons if less than 1/2,000 tons Percent Lime 3' 4 1/Day Not applicable Table Notes: 1 The minimum number of in -place density tests for acceptance will be 5. 2 Process control tests for gradation are not required if less than 250 tons are placed in a day. The minimum number of process control tests for gradation shall be one test for each 1,000 tons or fraction thereof. 3 Not to be used for incentive/disincentive pay. Test according to CP-33 and report results from Form 106 or Form 565 on Form 6. 4 Verified per Contractor's PC Plan. After completion of compaction, in -place density tests for process control shall be taken at the frequency shown in Table 106-3. The results shall be reported in writing to the Engineer on a daily basis. Daily plots of the test results with tonnage represented shall be made on a chart convenient for viewing by the Engineer. All of the testing equipment used for in - place density testing shall conform to the requirements of acceptance testing standards, except nuclear testing devices need not be calibrated on the Department's calibration blocks. For elements other than in -place density, results from process control tests need not be plotted, or routinely reported to the Engineer. This does not relieve the Contractor from the responsibility of performing such testing along with appropriate plant monitoring as necessary to assure that produced material conforms to the applicable specifications. Process control test data shall be made available to the Engineer upon request. (b) Owner Acceptance Testing. Owner Acceptance testing is the responsibility of the Department. For acceptance testing the Department shall determine the locations where samples or measurements are to be taken and as designated in Section 403. The maximum quantity of material represented by each test result, the elements, the frequency of testing and the minimum number of test results shall be per Table 106-3. The location or time of sampling will be based on the stratified random procedure as described in CP 75. Acceptance sampling and testing procedures will be per the Schedule for Minimum Materials Sampling, Testing and Inspection in the CDOT Field Materials Manual. Samples for Owner Acceptance testing shall be taken by the Contractor per the designated method. The samples shall be taken in the presence of the Engineer. Where appropriate, the Contractor shall reduce each sample to the size designated by the Engineer. The Page 95 of 292 December 18, 2024 Revision of Section 106 — Control of Material Contractor may retain a split of each sample which cannot be included as part of the Contractor's process control testing. Dispute of the acceptance test results per CP-17 shall not be allowed unless a provision for check testing has been included in the Contract and it has been successfully completed. All materials being used are subject to inspection and testing at any time before or during incorporation into the work. (c) Reference Conditions. Three reference conditions can exist determined by the Moving Quality Level (MQL). The MQL will be calculated per the procedure in CP 71 for Determining Quality Level (QL). The MQL will be calculated using only acceptance tests. The MQL will be calculated on tests 1 through 3, then tests 1 through 4, then tests 1 through 5, then thereafter on the last five consecutive test results. The MQL will not be used to determine pay factors. The three reference conditions and actions that will be taken are described as follows: 1. Condition green will exist for an element when an MQL of 90 or greater is reached, or maintained, and the past five consecutive test results are within the specification limits. 2. Condition yellow will exist for all elements at the beginning of production or when a new process is established because of changes in materials or the job -mix formula, following an extended suspension of work, or when the MQL is less than 90 and equal to or greater than 65. Once an element is at condition green, if the MQL falls below 90 or a test result falls outside the specification limits, the condition will revert to yellow or red as appropriate. 3. Condition red will exist for any element when the MQL is less than 65. The Contractor shall be notified immediately in writing and the process control sampling and testing frequency increased to a minimum rate of 1/250 tons for that element. The process control sampling and testing frequency shall remain at 1/250 tons until the process control QL reaches or exceeds 78. If the QL for the next five process control tests is below 65, production will be suspended. If gradation is the element with MQL less than 65, the Department will test one randomly selected sample in the first 1250 tons produced in condition red. If this test result is outside the tolerance limits, production will be suspended. (This test result will not be included as an acceptance test.) After condition red exists, a new MQL will be started. Acceptance testing will stay at the frequency shown in Table 106-3. After three acceptance tests, if the MQL is less than 65, production will be suspended. Production will remain suspended until the source of the problem is identified and corrected. Each time production is suspended, corrective actions shall be proposed in writing by the Contractor and approved in writing by the Engineer before production may resume. Page 96 of 292 December 18, 2024 Revision of Section 106 — Control of Material Upon resuming production, the process control sampling and testing frequency for the elements causing the condition red shall remain at 1/250 tons. If the QL for the next five process control tests is below 65, production will be suspended again. If gradation is the element with MQL less than 65, the Department will test one randomly selected sample in the first 1250 tons produced in condition red. If this test result is outside the tolerance limits, production will be suspended. Subsection 106.06 shall be deleted and replaced with the following: 106.06 Sampling and Testing of Portland Cement Concrete Paving. All Portland Cement Concrete Pavement, Item 412, shall be tested per the following process control and acceptance testing procedures: (a) Process Control Testing. Process control testing by the Contractor is mandatory. Process control testing for Portland Cement Concrete Pavement (PCCP) pay items shall not be measured and paid for separately but shall be included in the work. The Contractor's PCCP supplier and PCCP paving subcontractor shall be present and shall test the PCCP in accordance with Tables 106-4 and 106-5. The Contractor shall develop a process control plan (PCP) per the following: 1. Process Control Plan. For each element listed in Tables 106-4 or 106-5, the PCP must provide adequate details to ensure that the Contractor will perform process control. The Contractor shall submit the PCP to the Engineer at the Pre -construction Conference. The Contractor shall not start any work on the project until the Engineer has approved the PCP in writing. A.

The process control tests shall be independent of acceptance tests. B. Test Result Chart. Each process control test result, the appropriate area, volume, and the tolerance limits shall be plotted. The chart shall be posted daily at a location convenient for viewing by the Engineer. C. Quality Level Chart. The QL for each element in Table 106-4 or 106-5 shall be plotted. The QL shall be calculated per the procedure in CP 71 for Determining Quality Level. The QL shall be calculated on tests 1 through 3, then tests 1 through 4, then tests 1 through 5, then thereafter the last five consecutive test results. The area of material represented by the last test result shall correspond to the QL. D. F -test and t -test Charts. If flexural strength criteria is indicated, then the results of F -test and t -test analysis between the Department's verification tests of flexural strength and the Contractor's process control tests of flexural strength shall be shown on charts. The F -test and t -test shall be calculated per standard Page 97 of 292 December 18, 2024 Revision of Section 106 — Control of Material statistical procedures using all verification tests and process control tests completed to date. Only results from cast beams shall be used in the F & t analysis, flexural strengths from splitting tensile correlations shall not be included in the F & t analysis. When a verification test is completed, the F- test and t- test calculations shall be redone. The area of material represented by the last test result shall correspond to the F -test and t -test. A warning value of 5 percent and an alert value of 1 percent shall be shown on each chart. The chart shall be submitted to the Engineer electronically daily, as results become available. 2.

Testing Standards. The PCP shall indicate which testing standards will be followed. Acceptable standards are Colorado Procedures, AASHTO, and ASTM. The order of precedence is Colorado Procedures, then AASHTO procedures, then ASTM Procedures. The flexural strength test for process control shall be performed using 6 -inch by 6 -inch beams cast in plastic molds from a single sample of concrete, cured under standard laboratory conditions. A maximum of 72 hours after the beams are molded, they shall be removed from the plastic molds. After demolding, the beams shall be cured in either a 100% humidified cure room or lime treated testing tanks until the testing date. A minimum of three 7 -day and four 28 -day flexural strength tests are required. 4. Process Control (PC) Manager Qualifications. A PC Manager shall be identified in the PCP. The PC Manager shall not be the Contractor's Project Manager. The PC Manager shall be in charge of and responsible for all aspects of the process control testing. This person shall be present on the project at all times during PCCP paving. Failure to provide a PC Manager shall result in the stoppage of paving operations. The PC Manager shall possess one or more of the following qualifications: A. Registration as a Professional Engineer in the State of Colorado. B.

Page 98 of 292 December 18, 2024 Revision of Section 106 — Control of Material 5. Technician Qualifications. Technicians performing tests shall meet the requirements of Colorado Procedure 10. 6. Testing Equipment. All of the testing equipment used to conduct process control testing shall conform to the standards specified in the test procedures and be in good working order. The Contractor shall provide the following equipment and supplies which will not be paid for separately but shall be included in the work: A. Adequate space or a minimum of at least 300 square feet of a temperature controlled facility, separate from the onsite lab space is required to store all project PCCP flexural and compressive strength specimens is required. This facility shall be used exclusively for the molding and storage of concrete test specimens as required. A separate space will be required to house equipment and perform strength testing procedures. All equipment shall be maintained in satisfactory condition and calibration. Heavy rusting, mechanical, and/or electrical issues shall require testing and monitoring equipment to be replaced. These facilities shall be provided in addition to other facilities required in Section 620. The storage facility shall have sufficient water storage capacity for curing all required test specimens. The storage facility shall provide separate storage tanks for each type of required testing. (1) The storage facility shall provide proper ventilation and a continuous source of heating and cooling including backup power sources to maintain storage tank temperatures. (2) Each individual storage tank shall have continuously recording thermometers and sufficient blank charts for the project. The recording charts shall be changed regularly and used charts shall be kept in the PC notebook. The County's Engineer and Project Inspector shall be notified of the maximum and minimum temperatures in each tank on a daily basis. (3) Temperatures of each storage tank shall be recorded for the duration of the project or until the last OA strength test has been reported. (4) In the event, storage tanks drop below 60 °F or above 80 °F, all samples stored in the tank will be considered suspect and out of specification with the project requirements. Specimens shall be tested per the testing schedule for concrete specimens. If specimen test results indicate abnormalities or below the specified project strength requirements, the results shall be evaluated per the steps outlined below at the discretion of the Engineer. (i) The areas represented by the failing specimens shall be considered failing to meet the project specifications and shall be removed and replaced at no additional cost to the project. Page 99 of 292 December 18, 2024 Revision of Section 106 — Control of Material (ii) If in the Engineer's sole discretion, cored specimen sampling will be allowed, the core companion specimens shall be taken from with the slab areas represented by the failing specimens. Testing shall be completed per CP 65, Standard Practice for Evaluating Low Concrete Strength Test Results, Method B. (iii) X-raying of the in -place PCCP may be required prior to the start of any coring operations in order to determine where the welded wire mesh, tie bars and dowel bars are located. If the Contractor fails to provide proper curing or cold weather protection, the Contractor, at the Engineer's direction, shall use cores to determine the acceptance or rejection of the PCCP area(s) that are in question. Cores shall be taken with the following procedure. (i) The Engineer will notify the Contractor in writing that cores shall be taken in the PCCP area(s) that are in question. The locations for the coring will be directed by the Engineer. All coring, repairing, and testing shall be done at the expense of the Contractor regardless of the result. Cores shall be taken and tested per CP 65 Method B between 28 days and 45 days after PCCP placement. Cores shall be a minimum of 6 inches in diameter. Core bits used to cut the core shall have a 61/4" outside diameter which shall produce a true 6" core. At the direction of the Engineer, a minimum of 3 cores from a single slab area shall be obtained for the locations that are suspect. The flexural strength of the concrete shall be determined using the pre- production PCCP correlation to splitting tensile strength. Cores containing rebar steel, dowel bars, or other materials other than concrete shall be excluded from the splitting tensile testing results. If the splitting tensile strength of any one core differs from the average by more than 10 percent, that strength shall be discarded, and the average strength will be determined using the strength of the remaining two cores. If the strength of more than one core differs from the average by more than 10 percent, the average strength shall be determined using all three splitting tensile strengths of the cores. If the average core splitting tensile strength is greater than or equal to 600 psi, the concrete represented by the cores will be accepted or accepted with a price reduction per subsection 106.06. Page 100 of 292 December 18, 2024 Revision of Section 106 — Control of Material (ii) If the Contractor fails to maintain the tank temperatures within the specified range and the Engineer determines, in their sole discretion, that coring is required, the areas represented by the cylinders stored in the tank shall be cored and a pay reduction of 2.5% will be applied to the unit price of PCCP, regardless of the testing results. If the average core strength is between 615 psi (inclusive) and 645 psi, the PCCP shall be accepted by the Engineer but shall be assessed a pay reduction per subsection 105.06. If the average core strength is less than 600 psi, the PCCP shall be removed and replaced per subsection 105.03 and 105.06. (iii) Prior to coring, the Contractor shall submit a proposed repair method for the core hole for approval. The method shall use an approved high strength non -shrink concrete or grout patching material with of minimum compressive strength of 4,500 psi. The Contractor shall submit and follow the manufacturer's recommendations along with the repair method. The Engineer shall review and approve the repair method before the coring takes place. (iv) Time delays resulting due to the Contractor's failure to provide proper curing or cold weather protections will be considered non -excusable and will not be compensated. (v) The Contractor shall provide electronic copies of the testing results to the Engineer within two business days of receipt of the testing results. (vi) All costs associated with the repair of the core holes including the preparation and submittal of the repair method will not be measured, and paid for separately but shall be included in the work. B. A certified machine for testing flexural, compressive and splitting tensile strength of concrete specimens shall be provided by the Contractor. The machine shall have an opening size capable of housing the flexural strength apparatus, splitting tensile apparatus and compression heads. The machine shall have a square or rectangular bottom platen at least 2 inches thick. The machine shall have a minimum capacity of 300,000 lbs. The machine shall have a digital monitor capable of displaying load rate and total load. The following or an approved equal may be used: (1) Forney model number FHS-300 with a Co -Pilot digital monitor. (2) Humboldt model number HCM-3000 with an iD Digital Indicator. Page 101 of 292 December 18, 2024 Revision of Section 106 — Control of Material (3) Gilson model number MC -400 with Pro Controller. (4) Test Mark Industries CM -3000 with i720 Digital Indicator. Both the Contractor and the Engineer will use this machine for testing concrete specimens. The machine shall meet the requirements of AASHTO T97 and T22. After the machine has been certified and accepted by the Engineer it shall not be moved until all Portland cement concrete paving and flexural strength acceptance tests have been completed. A weekly check of the planeness of all bearing surfaces on the flexural strength apparatus shall be made and recorded in the Contractor's PC notebook for each week that flexural strength testing occurs. Swapping flexural strength apparatus, splitting tensile strength apparatus and compressive strength head will not require recertification of the test machine. C. Beam molds for molding all test specimens required. Beam molds shall have a cross section of approximately 6 inches by 6 inches. All beam molds shall be checked by the Contractor before being placed in service and monthly. The checks of each beam mold shall be recorded in the Contractor's PC notebook. This shall include all testing described in subsection 106.06. D. The Contractor shall supply an MIT Scan T2 or MIT Scan T3 and the associated tests plates when pavement thick acceptance is based on magnetic pulse induction (MPI). 7. Reporting and Record Keeping. The Contractor shall report the results of the tests to the Engineer electronically at least once per day. The Contractor shall assemble a process control (PC) notebook and update it daily. This notebook shall contain all worksheets, test results forms, test results charts and quality level charts for each of the elements listed in Table 106-5. The Contractor shall submit examples of worksheets, test result forms and test results charts per CP 12B as part of the Contractor's Process Control Plan (PCP). The Contractor shall submit the PC notebook electronically to the Engineer for review once a month on the date agreed to at the Pre -construction Conference. A list of recognized deficiencies will be returned to the Contractor within two workdays after submittal. Deficiencies may include, but are not limited to, the failure to submit the notebook on time or an absence of the required reports. For any month in which deficiencies are identified, the PC notebook will be submitted for review two weeks after the PC notebook is returned. Upon the second recognized deficiency the Engineer will notify the Contractor, and the pay estimate shall be withheld until the Contractor submits, in writing, a report detailing the cause for the recognized deficiency. The report shall include how the Contractor plans to resolve the deficiencies. Additional recognized deficiencies will result in a delay of the pay Page 102 of 292 December 18, 2024 Revision of Section 106 - Control of Material estimate until the Contractor has identified and resolved the deficiency along with revising and resubmitting his PCP to address these issues. Once the Engineer has reviewed and approved the revised PCP the estimate may be paid. Upon submittal of the PC notebook for the semi-final estimate, the PC notebook shall become the property of the Department. The Contractor shall make provisions such that the Engineer can inspect process control work in progress, including PC notebook, sampling, testing, plants, and the Contractor's testing facilities at any time. 8. PC Stockpile Management. For Projects greater than 25,000 SY of PCCP, the contractor shall perform PC Testing for each aggregate source. All aggregates furnished for the project shall conform to the range of tolerances listed in Table 106-4 when compared to the approved mix design gradations. Individual gradation testing shall be at a minimum frequency of 1/day or 1/1,000 tons, whichever is greater, as aggregate is delivered to the batch plant and incorporated into the stockpile. If material does not meet the listed tolerances, the area of the stockpile represented by the sample may be remixed and retested. If material fails to meet the tolerances a second time, it shall be rejected. If multiple batch plants are being utilized, aggregates at each plant shall be tested separately. Testing and Tracking methods shall be included in the Contractor's Process Control Plan. Table 106-4 — Individual A re• ate Gradation Tolerances Sieve Size Tolerance (%) ≥No. 4 ±6 No.8 — No. 30 ±4 No. 50 ±3 No. 100 ±2 No. 200 ±1 9. Optimized Gradation. The Contractor shall perform process control testing of the combined aggregate gradation (CAG) when an Optimized Gradation (OG) is used for Class P Concrete. The CAG testing frequency shall be three per day. Test one shall be sampled and tested after full production begins but before production reaches 100 cubic yards. Test two shall be sampled and tested after four hours of continuous production or production reaches 1,000 cubic yards, whichever comes first. Test three shall be sampled and tested after seven hours of continuous production or production reaches 1750 cubic yards, whichever comes first. The frequency shall be a minimum of one per day if production is less than 750 cubic yards. The Department will perform one gradation test each day that may be a split of one of the three daily PC samples. This data will not be used to determine acceptability of the material but as information only. The Contractor's gradation test data will be used to evaluate the gradation optimization based on the mix design optimization. Page 103 of 292 December 18, 2024 Revision of Section 106 — Control of Material When the Contractor's gradation test results fail to meet their optimization range, the Contractor shall immediately make corrections to bring the aggregate gradation optimization range and notify the Engineer. If two or more consecutive test results for any single day or two successive days are found to fall outside the optimization range, the Contractor shall immediately suspend production and provide a written corrective plan to the Engineer for approval before resuming production. Upon being allowed to resume production, the Contractor shall follow the daily sampling frequency. If the next two consecutive gradation tests indicate that the meet the optimization range, the Contractor may continue production. If the first two aggregate samples do not meet the optimization range, production shall be suspended. Before resuming production, the Contractor shall sample the individual aggregate stockpiles at two or more locations to determine the range of variability within each stockpile, make appropriate adjustments to the percentages for each aggregate component, and discharge and sample the combined aggregates. The combined aggregate gradation shall be tested to determine if the CF and WF fall inside the workability box. Production can resume if the optimization range is met. Production will continue to be suspended for additional evaluation of stockpiles and aggregate feed rates until gradation sampling and testing indicate the optimization range is met. All gradation test information during production shall be provided to the Engineer daily. The Contractor shall immediately report all gradation test data to the Engineer for evaluation during periods when production is suspended or upon resuming production. The Contractor will be notified in writing in all cases when production may resume or shall remain suspended. 10. Aggregate Moisture Content. An aggregate moisture content sample from the first 100 cubic yards of concrete shall be tested; then one test per 750 cubic yards shall be performed. The frequency shall be a minimum of one per day if production is less than 750 cubic yards per day. The moisture content sample maybe the same sample used for gradation PC testing. Moisture content of each aggregate shall be tested per CP 33. As they become available, results shall be immediately input into the batching computer and reflected on batch tickets. When Recycled Concrete Aggregate (RCA) is used, the moisture content of the RCA shall be at or above the absorption of the RCA. When the moisture content of the RCA is lower than the absorption of the RCA, the Contractor shall immediately suspend production and provide a written corrective plan to the Engineer for approval before resuming production 11. Box Test. When the Contractor is using a slipform paver, the Contractor shall perform a Box Test in accordance with CP-63 at the beginning of each day's paving. The Box Test shall show no more than 30 percent surface voids and an edge slump less than 1/4 inch. When the Box Test results fail to meet these requirements, the Contractor Page 104 of 292 December 18, 2024 Revision of Section 106 — Control of Material shall immediately make corrections and notify the Engineer. After corrective actions have been completed, the Contractor shall perform a Box Test. The Box Test shall show no more than 30 percent surface voids and an edge slump less than 1/4 inch. If two or more consecutive Box Test results fail to meet these requirements, the Contractor shall immediately suspend production and provide a written corrective plan to the Engineer for approval before resuming production. 12. Concrete Test Reports. The Contractor shall distribute electronically to the concrete supplier all flexural strength PC data for the concrete supplied to the project. The Contractor shall distribute the PC flexural strength data within two business days of the 7 -day and 28 -day flexural strength testing. The data shall include the flexural strength and batch ticket number at a minimum. 13. Concrete Test Reports. The Contractor shall distribute electronically to the concrete supplier all flexural -strength process control (PC) data for the concrete supplied to the project. The Contractor shall distribute the PC flexural strength data within two business days of the 7 -day and 28 -day flexural strength testing. The data shall include the flexural strength and batch ticket number at a minimum. (b) Acceptance Testing. Acceptance testing frequencies shall be per the Schedule (Owner Acceptance) in the CDOT Field Materials Manual. Except for flexural strength, acceptance tests will be conducted by and at the expense of the Department. Acceptance sampling and testing procedures will be per the CDOT Field Materials Manual with the following exceptions and inclusions: A split sample from an acceptance test shall not be used for a process control test. The Engineer will designate the location where samples are to be taken. Samples shall be taken by the Contractor per CP61. The Engineer will be present during the sampling and take possession of all acceptance samples. Samples transported in different containers will be combined and mixed before molding specimens. All materials are subject to inspection and testing at all times. Pavement thickness acceptance will be determined by cores or magnetic pulse induction (MPI). Destructive thickness testing will not be allowed without Engineer's consent. Acceptance tests for thickness using MPI shall be the Contractor's process control tests. MPI testing shall be per AASHTO T359. Acceptance tests for flexural strength shall be the Contractor's process control tests. The flexural strength tests shall be the average flexural strength of four test beams. The test beams shall be prepared according to AASHTO T23. The flexural strength of each specimen shall be measured according to AASHTO T97 with the following additional requirements: If the flexural strength of only one specimen differs from the average by more than 10 percent, that specimen shall be deleted, and the average strength shall be determined using the remaining three specimens. If the flexural strength of more than one specimen differs from the average by more than 10 percent, the test value shall be the Page 105 of 292 December 18, 2024 Revision of Section 106 — Control of Material average of all four specimens. Each set of four beams shall be tested at 28 days after molding. If the nominal maximum aggregate size of the mix is 3/4 inches or less, then the Contractor shall prepare three additional test beams using the 4x4x14 inch molds. The 4x4x14 inch specimens will be tested 28 days. The results of the 4x4x14 inch specimens will be for information only and will not be used to determine the acceptability of the concrete. Results of the 4x4x14 inch specimens will be reported to the Engineer with the corresponding acceptance test results. These additional specimens are being used to evaluate the validity of using smaller test specimens for acceptance. Acceptance flexural strength specimens shall be cast, cured, tested for flexural strength by the Contractor's PC Manager or Concrete strength certified technician, and witnessed by the Engineer or an approved Weld County Representative. Test results not witnessed by Weld County will not be accepted. The Contractor shall, in the presence of the Engineer, begin batch testing a minimum of 10 days prior to the start of concrete paving to develop a correlation curve per AASHTO T198 (ASTM C496) Splitting Tensile Strength of Cylindrical Concrete Specimens. Specimens shall be evaluated per CP65-19 method B. At least three splitting tensile strength specimens and four flexural strength specimens will be tested at 3, 7, 14, and 28 days. The splitting tensile strength and flexural strength specimens for each age used to develop the correlation curve shall be cast from the same batch of concrete being placed on the project. As stated in Subsection 105.06, Splitting Tensile Strength (AASHTO T198) sampling and testing by Weld County is being used to determine the validity of Splitting Tensile Strength as an acceptance criterion and not a ratio or correlation to Flexural. Weld County OA will mold 6 — (6 in x 12 in) specimens for Splitting tensile strength to be tested (3) at 7 days and (3) at 28 days, at a minimum of 1 set per day of concrete placement. The splitting tensile strength test for acceptance shall be the average splitting tensile strength of three test cylinders cast in plastic molds from a single sample of concrete and cured under standard laboratory conditions before testing. If the splitting tensile strength of any one specimen differs from the average by more than 10 percent, that specimen will be deleted, and the average strength will be determined using the remaining two specimens. If the splitting tensile strength of more than one specimen differs from the average by more than 10 percent, the average strength will be determined using all three specimens. Each set of three cylinders will be tested at 28 days after molding. (c) Verification Testing. Verification testing will be used only when flexural strength criteria is indicated and is the responsibility of the Department. The Department will determine the locations where samples or measurements are to be taken. The location of sampling shall be based on a stratified random procedure. Verification sampling and testing procedures will be per Sections 105, 106, 412, the Schedule for Minimum Materials Sampling, Testing and Inspection in the CDOT Field Materials Manual, and CP 13. Samples for verification testing shall be taken by the Contractor per CP 61 in the presence of the Engineer. Page 106 of 292 December 18, 2024 Revision of Section 106 - Control of Material An analysis of test results will be performed after all test results are known using the t -test and F -test statistical methods with an alpha value set at 0.05. If either the above t -test and F -test analysis shows a significant difference, then the following items shall be checked: comparison of beam fracture locations and types, computations, and flexural testing machine outputs, curing tank temperature charts, slump and air contents, plant batch tickets for major changes, review of sampling, molding, testing procedures, along with IAT check tests and any other investigations that may clarify the significant differences. If after a review of the data no reasons can be determined for the significant difference, the Department's test data shall be used for determining Quality Levels and Incentive or Disincentive according to the methods in this Section. (d) Check Testing. The Contractor and the Engineer shall conduct a check testing program (CTP) before the placement of any concrete pavement. The check testing program shall include a conference directed by the Engineer, the Contractor's testers, and the Department's testers concerning methods, procedures and equipment for flexural strength testing. Check testing shall be completed before any Portland cement concrete pavement is placed. A set of four beams will be molded by both the Contractor and the Department's project testers from a split sample.

The SWMP Administrator shall record the location of potential pollutants on the site map. Descriptions of the potential pollutants shall be added to the SWMP. At or before the Environmental Pre -construction Conference, the Contractor shall submit a Spill Response Plan for any petroleum products, chemicals, solvents, or other hazardous materials in use, or in storage, at the work site. See subsection 208.06(c) for Spill Response Plan requirements. Work shall not be started until the plan has been submitted to and approved by the Engineer. On -site above ground bulk storage containers with a cumulative storage shell capacity greater than 1,320 U.S. gallons, or storage containers having a "reasonable expectation of an oil discharge" to State waters, are subject to the Spill Prevention, Control and Countermeasure Plan (SPCC) Rule. Oil of any type and in any form is covered, including, but not limited to: petroleum; fuel oil; sludge; oil refuse; oil mixed with wastes other than dredged spoil. EPA Region 8 is responsible for administering and enforcing the SPCC plan requirements in Colorado. Before start of work, the Contractor shall submit a SPCC Form which has been approved by the EPA for the project. 6. The Contractor shall obtain a Construction Dewatering (CDW) permit from CDPHE anytime uncontaminated groundwater, including groundwater that is commingled with stormwater or surface water, is encountered during construction activities and the groundwater or commingled water needs to be discharged to State waters. If contaminated groundwater is encountered, a Remediation permit may be needed from CDPHE per Section 250. Page 124 of 292 December 18, 2024 Revision of Section 107 — Legal Relations and Responsibility to Public 7. Water from dewatering operations shall not be directly discharged into any State waters, unless allowed by a permit. Water from dewatering shall not be discharged into a ditch unless: (1) Written permission is obtained from the owner of the ditch. (2) It is covered in the approved CDW or Remediation Permit that allows the discharge. (3) A copy of this approval is submitted to the Engineer. A copy of the Permit shall be submitted to the Engineer before dewatering operations commencing. Construction Dewatering may be discharged to the ground on projects where CDPHE's Low Risk Guidance Document for Discharges of Uncontaminated Groundwater to Land are met. The conditions of this guidance are: i. The source of the discharge is solely uncontaminated groundwater or uncontaminated groundwater combined with stormwater and does not contain pollutants in concentrations that exceed water quality standards for groundwater referenced above. ii. Discharges from vaults or similar structures shall not be contaminated. Potential sources of contamination include process materials used, stored, or conveyed in the structures, or introduced surface water runoff from outside environments that may contain oil, grease, and corrosives. iii. The structures or introduced surface water runoff from outside environments that may contain oil and grease. iv. The groundwater discharge does not leave the LOC where construction is occurring. v. Land application is conducted at a rate and location that does not allow for any runoff into State waters or other drainage conveyance systems, including but not limited to streets, curb and gutter, inlets, borrow ditches, open channels, etc. vi. Land application is conducted at a rate that does not allow for any ponding of the groundwater on the surface, unless the ponding is a result of implementing control measures that are designed to reduce velocity flow. If the control measures used result in ponding, the land application shall be done in an area with a constructed containment, such as an excavation or berm area with no outfall. The constructed containment shall prevent the discharge of the ponding water offsite as runoff. vii. A visible sheen is not evident in the discharge. Page 125 of 292 December 18, 2024 Revision of Section 107 — Legal Relations and Responsibility to Public viii. Control measures are implemented to prevent any sediment deposited during land application from being transported by stormwater runoff to surface waters or other conveyances. ix. All control measures used shall be selected, installed, implemented, and maintained according to good engineering, hydrologic, and pollution control practices. The selected control measures shall provide control for all potential pollutant sources associated with the discharge of uncontaminated groundwater to land. The discharge shall be routed in such a way that it will not cause erosion to land surface. Energy dissipation devices designed to protect downstream areas from erosion by reducing the velocity of flow (such as hose attachments, sediment and erosion controls) shall be used when necessary to prevent erosion. All dewatering operations shall be recorded in the SWMP as follows: (1) The source is identified in the SWMP and updated by the SWMP Administrator. (2) The SWMP describes and locates the practices implemented at the site to control stormwater pollution from the dewatering of groundwater or stormwater. (3) The SWMP describes and locates the practices to be used that will ensure that no groundwater from construction dewatering is discharged from the LOC as surface runoff or to surface waters or storm sewers. (4) Groundwater and groundwater combined with stormwater do not contain pollutants in concentrations exceeding the State groundwater standards in Regulations 5 CCR 1002-41 and 42. If surface waters are diverted around a construction area and no pollutants are introduced during the diversion, a CDW Permit is not required. If the diverted water enters the construction area and contacts pollutant sources (e.g., disturbed soil, concrete washout, etc.), the Contractor shall obtain a CDW permit for the discharge of this water to State waters or to the ground. 8. At least 15 days before commencing dredging or fill operations in a watercourse, the Contractor shall provide written notification to owners or operators of domestic or public water supply intakes or diversion facilities if these facilities are within 20 miles downstream from the dredging or fill operations. Notification shall also be given to Owners or operators of other intakes or diversions that are located within five miles downstream from the site of the project. Identities of downstream owners and operators can be obtained from Colorado Division of Water Resources, Office of the State Engineer. Page 126 of 292 December 18, 2024 Revision of Section 107 — Legal Relations and Responsibility to Public 9. Temporary fill into wetlands or streams will not be allowed, except as specified in the Contract and permits. If such work is allowed, upon completion of the work all temporary fills shall be removed in their entirety and disposed of in an upland location outside of floodplains unless otherwise specified in the Contract. 10. Construction operations in waters of the United States as defined in 33 CFR Part 328.3, including wetlands, shall be restricted to areas and activities authorized by the U.S. Army Corps of Engineers as shown in the Contract. Fording waters will be allowed only as authorized by the U.S. Army Corps of Engineers 404 Permit. 11. Wetland areas outside of the permitted limits of disturbance shall not be used for storage, parking, waste disposal, access, borrow material, or any other construction support activity. 12. Pollutant byproducts of highway construction, such as concrete, asphalt, solids, sludges, pollutants removed in the course of treatment of wastewater, excavation or excess fill material, and material from sediment traps shall be handled, stockpiled, and disposed of in a manner that prevents entry into State waters, including wetlands. Removal of concrete waste and washout water from mixer trucks, concrete finishing tools, concrete saw, and all concrete material removed in the course of construction operations or cleaning shall be performed in a manner that prevents waste material from entering State waters and shall not leave the site as surface runoff. A minimum of 10 days before the start of the construction activity, the Contractor shall submit in writing a Method Statement for Containing Pollutant Byproducts to the Engineer for approval. The use of chemicals such as soil stabilizers, dust palliatives, herbicides, growth inhibitors, fertilizers, deicing salts, etc., shall be per the manufacturer's recommended application rates, frequency, and instructions. 13. All materials stored on -site shall be stored in a neat, orderly manner, in their original containers, with the original manufacturer's label.

Discharges authorized by the CDPS-SCP shall not cause, have the reasonable potential to cause, or measurably contribute to an exceedance of any applicable water quality standard, including narrative standards for water quality. All construction site wastes shall be properly managed to prevent potential pollution of State waters. The CDPS-SCP does not authorize on -site waste disposal. 22. The Contractor shall reclaim pollutants that discharge outside of the LOC. If discharging outside CDOT ROW, the Contractor shall coordinate access with the Project Engineer. (c) Stormwater Construction Permit. If the area of disturbance is greater than one acre, the Colorado Discharge Permit System Stormwater Construction Permit (CDPS-.SCP) shall be obtained by the Contractor. The Contractor and Weld County will be co-permittees. The Contractor shall coordinate with Weld County to become the Operator permittee of the respective CDPS-SCP upon award of the Contract. The Contractor shall provide a copy of the CDPS-SCP certification as the Operator to the Engineer before or at the Environmental Pre -construction Conference. No work shall begin until the CDPS-SCP permit with Owner and Operator has been approved by CDPHE. A copy of the CDPS-SCP shall be placed in the project SWMP The Contractor shall be responsible for complying with the applicable requirements of the CDPS-SCP. After the Contractor has completed the construction but before the final acceptance is issued by the County, arrangements shall be made to transfer the permit from the Contractor to the County. Before the transfer of the permit to the County, the Contractor shall ensure that the SWMP is complete and up to date. CDPHE-WQCD may require sampling and testing, on a case -by case basis. If CDPHE- WQCD requires sampling and testing, the CDPHE-WQCD will send a notification to the permittee. Reporting procedures for any monitoring data collected will be included in the CDPHE-WQCD's notification. If monitoring is required, the following applies: 1. The thirty (30) day average must be determined by the arithmetic mean of all samples collected during a 30 day consecutive period; and Page 129 of 292 December 18, 2024 Revision of Section 107 — Legal Relations and Responsibility to Public 2. A grab sample, for monitoring requirements, is a single "dip and take" sample. The Contractor shall provide a SWMP Administrator for this project. The Contractor is legally required to obtain all other permits associated with specific activities within or outside of the right of way, such as borrow pits, concrete or asphalt plant sites, waste disposal sites, or other facilities. Staging areas within a quarter mile, but not within Weld County right of way shall be considered a common plan of development and permits for these facilities require permitting in the Contractor's name as Owner and Operator. These permits include local agency, federal, or other stormwater permits. The Contractor shall consult with the Engineer and contact the CDPHE-WQCD or other appropriate federal, state, or local agency to determine the need for any permit. When a Utility Company has obtained a CDPS-SCP within a Weld County project area, before the Contractor being on -site, the Contractor shall coordinate with the Engineer and the Utility Company to transfer or reassign the permit area within the project's Limits of Construction to the Contractor and Weld County before work commencing. The Contractor shall not commence construction until CDPHE-WQCD issues a new CDPS-SCP identifying the Contractor as the Operator, and the permit is put in the SWMP. To initiate acceptance of the stormwater construction work (including seeding and planting required for erosion control), the Contractor shall request in writing a Stormwater Completion Walkthrough. The Engineer will set up the walkthrough. It will include the Engineer or designated representative, Superintendent or designated representative, and Stormwater Management Plan (SWMP) Administrator. Unsatisfactory and incomplete stormwater and sediment/erosion control work will be identified in this walkthrough and will be summarized by the Engineer in a punch list. The completed action items associated with the corrective work will be shown as completed on the punch list. Upon completion of all items shown, the Contractor shall notify the Engineer. Upon written agreement that the punch list is completed from the Engineer, the Contractor shall submit the appropriate form to the CDPHE-WQCD such that Weld County becomes the Operator permittee of the CDPS-SCP. Until the transfer of the CDPS-SCP has been approved by the CDPHE-WQCD, the Contractor shall continue to adhere to all CDPS-SCP requirements. Requirements shall include erosion control inspections, control measure installation, control measure maintenance, control measure repair including seeded areas, and temporary control measure removal. All documentation shall be submitted to the Engineer and placed in the SWMP. All costs associated with the Contractor applying for, holding, and transferring the CDPS- SCP permit between parties will not be measured and paid for separately, but shall be included in the work per subsection 107.02. Page 130 of 292 December 18, 2024 Revision of Section 107 — Legal Relations and Responsibility to Public (d) Measurement and Payment. 1. All the work listed in (b) above, including but not limited to dewatering, erosion control for dewatering, and disposal of water resulting from dewatering operations, including all costs for CDPHE-WQCD concurrences and permits, will not be measured and paid for separately, but shall be included in the work. 2. The Contractor shall be liable for any penalty (including monetary fines) applied to the Department caused by the Contractor's noncompliance with any water quality permit or certification. Monetary fines shall be deducted from any money due to the Contractor. If the monetary fine is in excess of all the money due to the Contractor, then the Contractor shall pay to the Department the amount of such excess. If monetary fines or penalties are applied to the Department while under stewardship of the Contractor but the exact amount is not known, the project retainage will be held by Weld County until the fines or penalties are resolved. If the monetary fine is in excess of all the money due to the Contractor, then the Contractor shall pay to the Department the amount of such excess. 3. The Contractor will not receive additional compensation, or time extensions, for any disruption of work or loss of time caused by any actions brought against the Contractor for failure to comply with good Engineering, hydrologic and pollution control practices. 4. If a spill occurs as a direct result of the Contractor's actions or negligence, the cleanup of such spill shall be performed by the Contractor at the Contractor's expense. 5. Areas exposed to erosion by fire resulting from the Contractor's operations shall be stabilized per Section 208 by the Contractor and at the Contractor's expense. End of Section Page 131 of 292 December 18, 2024 Revision of Section 108 - Prosecution and Progress Revision of Section 108 - Prosecution and Progress Section 108 of the Standard Specifications is hereby revised for this project as follows: Subsection 108.01 shall be deleted and replaced with the following: 108.01 Subletting of Contract. The Contractor shall not sublet, sell, transfer, assign, or dispose of the Contract or Contracts, or any portion thereof without written permission of the Engineer. Before beginning any work by the subcontractor, the Contractor shall request permission from the Engineer by submitting a completed Sublet Permit Application, CDOT Form No. 205 via the B2GNow software system. The subcontracted work shall not begin until the Contractor has received the Engineer's written permission. The Contractor shall make all project -related written subcontracts, agreements, and purchase orders available to the Engineer for viewing, upon request, and at a location convenient to the Engineer. When the project does not have CDOT funding, the B2GNow software system will not be used and the Contractor shall submit a hardcopy of the CDOT Form No. 205 to the Engineer for review and acceptance. The Contractor will be permitted to sublet a portion of the Contract. However, the Contractor's organization shall perform work amounting to 30 percent or more of the total original contract amount. Any items designated in the Contract as "specialty items" may be performed by subcontract. The cost of "specialty items" so performed by subcontract may be deducted from the total original contract amount before computing the amount of work required to be performed by the Contractor's own organization. The original contract amount includes the cost of material and manufactured products which are to be purchased or produced by the Contractor and the actual agreement amounts between the Contractor and a subcontractor. The proportional value of a subcontracted partial contract item will be verified by the Engineer. When a firm both sells material to a prime contractor and performs the work of incorporating the materials into the project, these two phases shall be considered in combination and as constituting a single subcontract. The calculation of the percentage of subcontracted work shall be based on subcontract unit prices. Subcontracts or transfer of Contract shall not release the Contractor of liability under the Contract and Bond. Failure to comply with all contractual obligations may lead to the suspension, debarment, or both of the subcontractor, and if necessary, the Contractor as stipulated in the "Rules". When the project has CDOT funding, all firms to which the contractor will be subletting a portion of the contract shall have an account created in the B2GNow software system. If the firm does not have an account created approval of the form 205 may be withheld. When the project has CDOT Funding, Form FHWA 1273 titled Required Contract Provisions Federal -Aid Construction Contracts shall be attached to all subcontracts. As described in Section Page 132 of 292 December 18, 2024 Revision of Section 108 — Prosecution and Progress I. General, the provisions of Form FHWA 1273 apply to all work performed under the Contract and are to be included in all subcontracts with the following modification: 1.

The Contractor and subcontractors shall submit a Contractor Fringe Benefit Statement, either for each individual, or for groups of people, for all employees who perform work on the project and whose wages are covered by the Davis -Bacon Related Acts. Other approved deductions shall be noted within the LCPTracker system and supporting documentation shall be attached. If for any reason the fringe benefits are altered during the life of the contract, the Contractor, subcontractor, or both shall submit a revised Contractor Fringe Benefit Statement to accurately reflect the changes. 3. Each construction subcontractor shall submit their payrolls directly into LCPTracker for approval by the Contractor. In the event that the Contractor or the sub -contractors do not submit properly completed payrolls to LCPTracker, Weld County shall withhold any pay applications until all payrolls have been properly submitted and accepted. 4. The Contractor shall submit and approve their own payrolls in LCPTracker. The Contractor is responsible for ensuring all of the subcontractors submit and approve their own payrolls in LCPTracker. The Contractor shall be responsible for providing all technical support to all of the subcontractors. In the event, the Contractor cannot provide the technical support to all subcontractors, the Contractor shall coordinate directly with LCPTracker for the required technical support. Weld County will not provide technical support to the Contractor or subcontractors. 5. The Engineer will approve or reject weekly payrolls for the Contractor. Subsection 108.02 shall be deleted and replaced with the following: 108.02 Notice to Proceed. The Contractor shall not commence work before the issuance of a Notice to Proceed.

Subsection 108.04, paragraph 1 shall be deleted and replaced with the following: 108.04 Payment Schedule. The Contractor shall prepare a payment schedule which shall show the dollar amount of work the Contractor expects to complete, including Force Accounts, retainage and expected incentive payments, by the progress estimate date each month for the duration of construction. The payment schedule shall be signed by the Contractor's authorized agent. The payment schedule shall show the dollar amount of work the Contractor expects to complete for every month on the Contract from commencement of work to Project Acceptance. The fiscal year (January 1 to December 31) totals shall also be shown on the payment schedule. The payment schedule may be prepared using standard spreadsheet software such as MS Excel and submitted in electronic format. Subsection 108.04(b), paragraph 2 shall be deleted and replaced with the following: If the update has any Weld County Fiscal Year (January 1 to December 31) payment in excess of the encumbrance amount, the Department may, in its sole discretion, approve the update. If the Department does not approve the update the Contractor shall either revise the payment schedule or proceed at his own risk. The risk is either not being paid in a timely manner, or not being paid at all for any amounts over the encumbrance amount. If the Contractor proceeds at his own risk, then payment for the at -risk work will be dependent upon ratification of this work by the Weld County Controller. Subsection 108.08, paragraph 2 shall be deleted and replaced with the following: The Contractor may work between sunrise and % hour before sunset, Monday through Friday excluding holidays, without written consent from the Engineer. If the Contractor wishes to work outside of these hours of operation, they may request to do so by providing the Engineer with a written request outlining the reasons for the request. The Engineer is under no obligation to approve hours of operation outside of the hours listed above. The Contractor shall not carry on construction operations on Saturdays, Sundays, or holidays unless previously arranged and approved by the Project Manager and Inspector Supervisor. The Page 135 of 292 December 18, 2024 Revision of Section 108 — Prosecution and Progress Contractor shall not perform construction operations on any three or four -day holiday weekend without prior written approval. Requests for weekend construction operations shall be presented in writing to the Engineer and Inspector Supervisor no later than Wednesday at 5 p.m. before the weekend in which the work will be performed. Written requests received after the deadline will be reviewed on a case by case basis. The Engineer and Inspector Supervisor are not required to provide written approval for weekend inspectable construction operations requests. In the event, the weekend construction operations involve inspectable work (operations requiring a construction inspector), the Contractor shall provide a credit on the next pay application to the County. The amount credited shall be $400.00 for the first four hours (four hour minimum) and $100.00 per hour per day thereafter for each Inspector or Engineer required to perform inspections on the inspectable work. Construction operations shall stop at 5 p.m. the day before the start of the holiday weekend. Construction operations may resume after the holiday weekend has passed. The Contractor shall only make emergency repairs and provide proper protection of the work and the traveling public on the holiday weekend days. Subsection 108.08(a)(2) shall be deleted and replaced with the following: (2) Calendar Day Contract. When the work is on a calendar day basis, one calendar day of contract time will be assessed for each calendar day from the date that Contract time starts including Saturdays, Sundays, and holidays. Calendar Day Contracts have been adjusted before bid advertisement to account for no work on Saturdays, Sundays, and holidays by increasing the calendar days by the appropriate number of days. As stated in subsection 108.08, no inspectable construction operations shall occur on Saturdays, Sundays, and holidays unless prior written approval has been granted by the Engineer. No weather days or less than full time charges days will be granted in this contract. Subsection 108.08(b) shall be deleted and replaced with the following: (b) Completion Date Contract. When the Contract specifies a completion date, all work under the Contract shall be completed on or before the date specified. Completion Date Contracts have been adjusted before bid advertisement to account for Saturdays, Sundays, and holidays by adjusting the completion date by the appropriate number of days. As stated in subsection 108.08, no inspectable construction operations shall occur on Saturdays, Sundays, and holidays unless prior written approval has been granted by the Engineer. No extension of the completion date will be allowed for inclement weather, foreseeable causes, or conditions under the control of the Contractor. If all work under the Contract is not completed on or before the specified completion date, contract time will be assessed for each additional calendar day per with subsection 108.8(a)(2) and liquidated damages will be assessed to the Contractor per day, per Table108-2 until the completion of the project. Page 136 of 292 December 18, 2024 Revision of Section 108 - Prosecution and Progress Subsection 108.09 shall be deleted and replaced with the following: 108.09 Failure to Complete Work on Time. A daily charge will be made against the Contractor for each calendar day, including free time, that any work remains uncompleted after the elapse of contract time. This daily charge will be deducted from any money due the Contractor. This deduction will not be considered a penalty, but as liquidated damages. Upon issuance of the Notice of Final Acceptance, the Contractor shall submit all required paperwork required to close out the project within 20 days. Failure to provide the required paperwork will result in the assessment of liquidated damages as outlined in Table 108-2. The schedule of liquidated damages set forth below is an amount, agreed to by the Contractor and the Department, as reasonably representing additional construction engineering costs incurred by the Department if the Contractor fails to complete performance within the contract time. Due account shall be taken of any adjustment of the contract time for completion of the work granted under the provisions of subsection 108.08. Permitting the Contractor to continue and finish the work or any part thereof after elapse of contract time will not operate as a waiver on the part of the Department of any of its rights under the Contract. Deductions assessed as liquidated damages under this subsection shall not relieve the Contractor from liability for any damages or costs resulting from delays to other contractors on the project or other projects caused by a failure of the assessed Contractor to complete the work according to contract times.

Pay Reductions. A pay reduction will be made against the Contractor for each calendar day, including free time, that the Contractor is out of compliance with the Specifications. This daily charge will be deducted from any money due to the Contractor. The pay reduction amounts are generally defined in the applicable sections of the Specifications. Where pay reductions are not defined in the specifications, the pay reduction amount shall follow Table 108-2 of these specifications. End of Section Page 138 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment Revision of Section 109 — Measurement and Payment Section 109 of the Standard Specifications is hereby revised for the project as follows: Subsection 109.01 shall be deleted and replaced with the following: 109.01 Measurement of Quantities. All work completed under the Contract will be measured by the Engineer according to United States standard measure (English units). A station when used as a definition or term of measurement will be 100 linear feet. The method of measurement and computations to be used in determination of quantities of material furnished and of work performed under the Contract will be those methods generally recognized as conforming to good engineering practice. Unless otherwise specified, longitudinal measurements for area computations will be made horizontally, and deductions will not be made for individual structures having an area of 9 square feet or less. Unless otherwise specified, transverse measurements for area computations will be the neat dimensions shown on the plans or as ordered in writing by the Engineer. Structures will be measured according to neat lines shown on the plans or as altered to fit field conditions. Items which are measured by linear foot, such as pipe culverts, guardrail, underdrains, etc., will be measured parallel to the base or foundation upon which the structures are placed, unless otherwise shown on the plans. In computing volumes of excavation and embankment, the average end area method or the method incorporated into the Department's computer earthwork program will be used. The term "gauge," when used in connection with the measurement of plates, will mean the U.S. Standard Gage. When the term "gauge" refers to the measurement of wire, it will mean the wire gage specified in ASTM A510. The term "ton" will mean the short ton consisting of 2,000 pounds avoirdupois. Materials measured or proportioned by weight shall be weighed on accurate scales. Scales shall be accurate within the allowable tolerances as prescribed by State law. The scales shall be tested for accuracy by the Colorado Department of Agriculture or an approved Colorado Department of Agriculture vendor (https://www.colorado.gov/pacific/aginspection/scale- companies ) at least once each year, each time the scales are relocated, and as often as the Engineer may deem necessary. Scales shall be furnished by the Contractor, or the Contractor may utilize commercial scales. Page 139 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment Scales shall be operated according to the Colorado Department of Agriculture's regulations. Weighers, scales, scale tickets, scale house, and verification of the scales' accuracy will not be measured and paid for separately but shall be included in the work. The Contractor may use either certified hopper scales or certified platform scales. When platform scales are used to weigh vehicles carrying material paid for by weight, a certified weigher shall weigh each vehicle. Hopper scales used to directly measure material paid for by weight shall be operated by certified weighers and provide an accurate net weight. The operator of each vehicle carrying material measured and paid for by weight shall obtain a scale ticket (certificate of correct weight) from the certified weigher and deliver the ticket to the Engineer at the point of delivery of the material. The scale ticket shall include the following information: (1) Project Number. (2) Date. (3) Ticket Number. (4) Haul Unit Number. (5) Form 43 Number and Mix Type (HMA and SMA Only) (6) Plant Location (7) Gross Weight. (8) Tare Weight. (9) Net Weight. (10) Material Type. (11) Certified Weigher's Name. Vehicles used to haul material being paid for by weight shall bear a plainly legible identification mark. Each of these vehicles shall be weighed empty daily at times directed by the Engineer. The Contractor shall furnish to the Engineer, in writing, a vehicle identification sheet that lists the following for each delivery vehicle to be used on the project: (1) Identification mark. (2) Vehicle length. Page 140 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment (3) Tare weight. (4) Number of axles. (5) The distance between extreme axles. (6) Information related to legal weight, including the Permit Number and permitted weight of each vehicle for which the State has issued an overweight permit. This information shall be furnished before time of delivery of the material and at any subsequent time the Contractor changes vehicles, combination vehicles, axle length relationships, or overweight permitting of vehicles. All materials (304 Class 6 Base Course, 403 HMA, etc.) delivered to the project site that have been weighed by a certified scale, shall be issued tickets by the source certified weigh master. These tickets will be collected and compiled by a representative of the Contractor at the project's placement site. Tickets will be made available for inspection during placement to the Engineer or Inspector at all times. The Contractor will submit, in an envelope, within 48 hours of material placement, the following: (1) Truck Tare List (2) Original Scale Tickets (3) Weld County Materials Quantity Reconciliation Sheet, signed by Contractor's representative. Material quantity discrepancies, such as waste or rejected loads will be tracked on the reconciliation sheet submitted by the Contractor. Contractor will be made aware of any discrepancy immediately by the inspector. Ticket package will be submitted to the inspector or engineer within 48 hours of placement. For material quantity submittals beyond these 48 hours, a price reduction on the material in question will occur as follows: • less than 24 hours=2% • 25 - 48 hours=5% • 48 hours to 72 hours=25% • Greater than 72 hours=100% Weighers using hopper scales solely for batching materials not measured and paid for by weight need not be certified. Page 141 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment The Engineer will randomly verify the accuracy of the certified weigher on every project where the weights are manually entered on the scale ticket. This verification will consist of at least one comparison check on the project. Additional verification checks may be required as determined by the Engineer. The Engineer will randomly select a loaded truck after the truck has been issued a scale ticket by the certified weigher. The loaded truck will then be reweighed, in the presence of the Engineer, on the same scale and the weight compared with the weight on the scale ticket. Reweighed loads shall be within the tolerance of 200 pounds plus or minus. The Engineer will also verify the accuracy of computerized scales. Computerized scales are scales that automatically print weights on the scale ticket. This verification will consist of at least one comparison check when the project requires more than 2,500 tons of material to be weighed. This comparison check shall be made by reweighing a loaded vehicle. The Contractor shall either provide a second certified scale or select a second certified scale in the vicinity to be used for the comparison check. Comparison checks shall be performed using the following procedures: (1) Hopper Scale. A loaded truck will be randomly selected by the Engineer. The loaded truck shall be weighed on a certified platform scale to record the gross weight. The truck shall be unloaded and weighed again on the same scale to record the tare weight. The tare weight shall be subtracted from the gross weight and compared against the net weight recorded on the scale ticket. (2) Platform Scales. The Engineer will randomly select a loaded truck. The loaded truck shall be reweighed on a second certified scale and the gross weight shall be compared against the gross weight on the first scale ticket. Should a comparison check reveal a weight difference of more than one percent, a second comparison check shall be performed immediately. If the weight differences of both comparison checks exceed the one percent limit, the Contractor shall immediately stop weighing and the scale shall be recertified and resealed at the Contractor's expense. The necessary adjustments as indicated by the recertification will be made to all scale tickets issued since the last certification or on the entire project, whichever occurred later, unless the Contractor demonstrates to the satisfaction of the Engineer that the defect in the scale was present for a lesser period of time. If it is necessary to recertify a scale, and more than 2,500 tons of material remain to be weighed, another scale comparison check shall be made. All comparison checks shall be made at the Contractor's expense. Materials to be measured by volume in the hauling vehicle shall be hauled in approved vehicles and measured at the point of delivery. Vehicles for this purpose may be of any size or type, provided the body is shaped so the actual contents may be readily and accurately determined. All vehicles shall be loaded to their water level capacity and all loads shall be leveled when the vehicles arrive at the point of delivery. Page 142 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment Water used in the work will be measured by the M Gallon or 1,000 U.S. Gallons. The weight of inherent moisture in the material will not be deducted. Water added for the Contractor's convenience will not be paid for. Water may be measured by either volume or weight. Water meters shall be accurate within a range of plus or minus 3 percent. When water is metered, the Contractor shall use an approved metering device and shall furnish the Engineer a certificate showing the meter has been accurately calibrated within the time allowed in the following schedule: 2 inch=4 years 4 inch to 6 inch=2 years 8 inch to 10 inch=1 year Water meters shall be calibrated when the Engineer determines there is reason to believe the meters are not accurate within the allowable tolerance. If water meter accuracy is found acceptable, the cost involved in checking the water meter shall be at the Department's expense. If the water meter accuracy is found unsatisfactory, the cost involved in checking the water meter shall be at the Contractor's expense. For those materials specified to be measured by the cubic yard, an acceptable method of computing volumes of excavation is to determine a weight to volume factor and convert weight to volumes by means of the factor. Colorado Procedure 80 as described in the CDOT Field Materials Manual shall determine the weight to volume factor. The number of tests used to determine the material weight to volume factor will be determined by the Engineer. The locations where the tests are taken shall be at those locations specified in the "Method of Measurement" for the particular bid item; i.e., Unclassified Excavation - in its original position: Embankment Material - in its final compacted position, etc. Asphalt materials will be measured by the gallon or ton. Volumes will be measured at 60°F or will be corrected to the volume at 60°F using ASTM D1250 for asphalts or ASTM D633 for tars. Net certified scale weight or weight based on certified volumes in the case of rail shipments will be used as a basis of measurement, subject to correction when asphalt material has been lost from the car or the distributor, wasted, or otherwise not incorporated in the work. When asphalt materials are shipped by truck or transport, net certified weight or volume subject to correction for loss or foaming will be used for computing quantities. Cement will be measured by the ton. Timber will be measured by the number of thousand feet board measure or MFBM actually incorporated in the structure. Measurement will be based on nominal commercial widths and thicknesses. Page 143 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment The term "lump sum" when used as an item of payment will mean complete payment for the work described in the Contract. When a complete structure or structural unit (in effect, "lump sum" work) is specified as the unit of measurement, the unit will include all necessary fittings and accessories. Rental of equipment will be measured in hours of actual working time and necessary traveling time of the equipment within the limits of the project. If special equipment has been ordered by the Engineer in connection with force account work, travel time and transportation to the project will be measured. If equipment has been ordered held on the job on a standby basis by the Engineer, and is not otherwise utilized by the Contractor, standby rental rates for the equipment will be paid at the rates specified in subsection 109.04. When standard manufactured items are specified such as fence, wire, plates, rolled shapes, and pipe conduit, and these items are identified by gage, unit weight, and section dimensions, the identification will be considered to be nominal weight or dimensions. Unless more stringently controlled by tolerances in cited specifications, manufacturing tolerances established by the industries involved will be accepted. The following work will not be measured and paid for separately but shall be included in applicable unit prices for which the work is required. The list below is not all-inclusive and there may be other items which are considered incidental to the project: (1) Earthwork requiring more than one handling. (2) New materials (if required) for resetting fences. (3) Fine grading (4) Soil conditioner unless otherwise identified in the Contract. (5) Fertilizer unless otherwise identified in the Contract. (6) Staging areas (7) Additional temporary construction easements if desired by the Contractor (8) Coordination with utility companies (9) All water Subsection 109.06(a), Paragraph 1 shall be deleted and replaced with the following: (a) Standard Amount Retained. The Department will make a deduction from the progress estimate in the amount considered necessary to protect the interests of the County, pursuant to Section 24-91-103, CRS. The amount retained will be 5% of the value of the Page 144 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment completed work, to a maximum of 5% of the contract amount. No retainage shall be released before Final Acceptance. No retainage shall be released if there are CDPHE fines for stormwater items while under the stewardship of the Contractor until the fines are resolved. No further amount will be retained if the Contractor makes satisfactory progress in the contract work. The amount retained will be in effect until such time as final payment is made, with the following exception which requires the Contractor's written request and consent of the Surety: Upon completion and acceptance of the project, after the project quantities are finalized, and the Contractor has submitted the necessary forms, the Engineer may make reduction in the amount retained. Subsection 109.06(e) shall be deleted and replaced with the following: (e) Prompt Payment. The Contractor shall pay subcontractors and suppliers for all work that has been satisfactorily completed within seven (7) calendar days after receiving payment for work from the Department. For the purpose of this section only, work shall be considered satisfactorily complete when the Department has made payment for the work. The Contractor's subcontracts shall include a prompt payment provision, requiring prompt payment for all subcontractors and suppliers. The Contractor shall ensure that all subcontractors and suppliers at every tier are promptly paid. If the Contractor or its subcontractors fail to comply with this provision, the Engineer will not authorize further progress payment for work performed directly by the Contractor or the noncompliant subcontractor/supplier until making the required payments and providing the reporting documentation required in subsection 109.06(h). Subsection 109.06(h) shall be deleted and replaced with the following: (h) Monthly Reporting. The flow chart below provides information regarding the process for prompt payment on both non-CDOT and CDOT funded projects. For Weld County projects with CDOT funding, the Contractor shall record all payments to subcontractors and suppliers by completing an audit in the B2GNow System within fifteen (15) days of paying the subcontractors or suppliers. If the Contractor has good cause for delay as described in subsection 109.06(g), the Contractor shall include the justification in its monthly audit. Once the Contractor enters a payment to a subcontractor or supplier, the subcontractor or supplier will receive a notice to confirm payment. The subcontractor or supplier shall notify the Contractor and the Engineer in writing if there is an issue with the prompt payment. The subcontractor or supplier shall have fifteen (15) days from the notice to confirm payment or report an issue. If the subcontractor or supplier does not report a prompt payment issue within fifteen (15) days from the Contractor's monthly reporting, the subcontractor waives Weld County's and CDOT's assistance in resolving the prompt payment issue and the monthly audit will be closed. This provision should not be construed to limit the lower tier subcontractor's or supplier's contractual remedies. Failure to submit complete and accurate data in the B2GNow System shall be grounds for Weld County to withhold subsequent payments or retainage from the Contractor. Page 145 of 292 December 18, 2024 Revision of Section 109 — Measurement and Payment If a subcontractor or supplier is also a payor, the subcontractor or supplier shall also report all prompt payment to its lower tier subcontractors and suppliers within seven (7) days of receiving the Contractor's payment. The lower tier subcontractor or supplier shall notify the Contractor, subcontractor/supplier, and Weld County in writing if there is an issue with prompt payment. If the lower tier subcontractor or supplier does not report a prompt payment issue within fifteen (15) days from the Contractor's monthly reporting, the subcontractor waives Weld County's and CDOT's assistance in resolving the prompt payment issue and the monthly audit will be closed. This provision should not be construed to limit the lower tier subcontractor's or contractor's contractual remedies. Failure to submit complete and accurate data in the B2GNow System shall be grounds for Weld County to withhold subsequent payments or retainage from the Contractor.

The material shall contain less than 20 percent by volume of material passing the 75 µm (No. 200) sieve based on visual inspection. Page 158 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment E. Particles retained on the 4.75 mm (No. 4) sieve shall not be composed of non -durable bedrock types. Rock fill can be placed without moisture density control as described in subsection 203.07(b). Non -durable bedrock shall be identified and classified using Colorado Procedure CP-L 3104. Any material classified as Soil -like Non -durable (S -N) as defined in the procedure shall be pulverized, broken down and processed to 6 -inch maximum particle sizes before incorporation into embankment fill. These materials shall be placed and compacted as "soil embankment" per subsection 203.07(a). Non -durable bedrock particles in excess of 6 inches shall not be placed into embankment fill. If recycled concrete or asphalt are to be incorporated into embankment fill, the maximum dimension permitted for concrete is 24 inches and the maximum dimension permitted for asphalt is 12 inches. Embankment material imported onto the project will be tested for water soluble sulfates using CP-L 2103 Method B. The average of three consecutive tests shall show that the sulfate content is not greater than that corresponding to the sulfate exposure level specified in the Contract. No single test shall have a sulfate content more than 20 percent greater than that corresponding to the sulfate exposure level specified in the Contract. When there is a single failing test, the remaining sample shall be split into four equal portions. Weld County shall receive one portion, the Contractor shall receive one portion, and the remaining two portions shall be retained for third party dispute testing. Weld County's Lab and the Contractor's Lab shall retest the sample. If the results from the two labs are within 10 percent of each other, the results will be averaged. The averaged result will be used for determining Contract compliance. If the results from the labs are not within 10 percent of each other, the remaining split samples shall be sent to an independent laboratory for testing using CP-L 2103. The independent laboratory shall be mutually agreed upon by Weld County and the Contractor. The independent lab's test result will be used for determining Contract compliance. If the water soluble sulfate content is less than that corresponding to the sulfate exposure level specified in the Contract, Weld County will bear all costs associated with the independent lab test. If the soluble sulfate content is greater than that corresponding to the sulfate exposure level specified in the Contract, all costs associated with independent lab testing shall be at the Contractor's expense. Embankment represented by failing tests shall be removed from the project and replaced at the Contractor's expense. Imported material used for backfilling pipes shall be tested for compatibility with the selected pipe material. When non -Reinforced Concrete Pipe or Reinforced Concrete Pipe is used, the imported material shall be tested for sulfates and pH to ensure that it is compatible with the selected pipe material. When Corrugated Steel Pipe, Bituminous Coated Corrugated Steel Pipe, or Precoated Corrugated Steel Pipe is used, the imported materials shall be tested for sulfates, chlorides, pH, and resistivity. Page 159 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment When Aramid Fiber Bonded Corrugated Steel Pipe or Corrugated Aluminum Pipe is used, the imported material shall be tested for pH and resistivity. When Plastic Pipe is selected, the imported material does not need to be tested for sulfates, chlorides, pH, and resistivity. Sulfates, chlorides, pH, and resistivity shall be determined by the following procedures: (1) Water soluble sulfates using CP-L2103 Method B. (2) Chlorides using CPL 2104. (3) Resistivity using ASTM G57 (4) pH using ASTM G51. The average of three consecutive tests shall show the imported material's sulfate, chloride, pH and resistivity is not greater than the limits corresponding to the Pipe Class in Table 203-1 or 203-2 for the pipe class specified in the Contract. No single test shall have a result more than 20 percent greater than that corresponding to the limit in Table 203-1 or Table 203-2 for sulfates, chlorides and resistivity. No single test shall have a result more than 5 percent outside the limit in Table 203-1 for pH. The remaining sample material from a single failing test shall be split into three equal portions. Weld County shall receive one portion, the Contractor shall receive one portion and the remaining portion shall be retained by the Project. Weld County and the Contractor's Lab shall retest the failed sample; if the results from those tests are within 10 percent of each other, the results will be averaged. The averaged result will be used for Contract compliance. If the results from the Labs are not within 10 percent of each other, the remaining sample portion shall be sent to an independent laboratory for testing using the testing requirements specified above. The independent laboratory shall be mutually agreed upon by Weld County and the Contractor. The Independent Lab's test result will be used for Contract compliance. If the imported material's sulfates, chlorides, and resistivity are less than the limits and the pH is within the limits in Table 203-1 or 203-2, Weld County will bear all costs associated with the independent lab test. If the imported material's sulfates, chlorides, and resistivity is greater than the limits and the pH is outside the limits in Table 203-1 or 203-2, all costs associated with independent lab testing shall be at the Contractor's expense. If the sulfates, chlorides, and/or resistivity test results of the imported materials are outside of the limits in Table 206-1 or 206-2, and a different pipe class is required other than those specified in the Contract, the Contractor shall provide a compatible pipe class at no additional cost to the County. Embankment represented by failing tests shall be removed from the project and replaced at the Contractor's expense.

The contractor shall ensure that all earthwork activities are performed with machine control to the accuracies specified below. The excavations and embankments shall be finished to smooth and uniform surfaces conforming to the typical sections specified. Variation from the subgrade plan elevations specified shall not be more than 0.08 foot. Where asphalt or concrete surfacing materials are to be placed directly on the subgrade, the subgrade plane shall n ot vary more than 0.04 foot. Materials shall not be wasted without written permission of the Engineer. Excavation operations shall be conducted so material outside of the slope limits will n ot be disturbed. Before beginning grading operations, all necessary clearing and grubbing in that area shall have been performed per Section 201. S ubsection 203.06 shall be deleted and replaced with the following: 203.06 General Embankment Construction Requirements. Contractor Process Control is mandatory for this element. The Contractor's Process Control Representative shall be certified with Western Alliance for Quality Transportation Construction (WAQTC) Embankment and Base Testing and CDOT's Excavation, Embankment, and Soil Inspection certification course. Only approved equipment and methods proposed by the Contractor in Method Statements (see Section 108.03(j)), shall be used in the placement of, moisture conditioning and compaction of, and/or reconditioning of cut/fill and embankment materials. The Contractor shall be responsible for determining the moisture conditioning, the type of equipment, and number of passes that are needed to achieve adequate compaction; however, compression type or vibratory rollers are required for granular materials, and sheepsfoot rollers are required for cohesive soils. Water trucks, haul trucks, scrapers shall not be used as compaction equipment or as interim compactive measures, apart from shouldering materials. Page 161 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment The Contractor shall use approved equipment or attachments for conditioning/mixing during embankment placement and/or cut/fill reconditioning, for soils classified as A-4 to A-7 to ensure consistent moisture conditioning without disturbing compaction of preceding lifts. Dozer ripping shall not be allowed unless approved in writing by Engineer. Embankment construction shall include preparation of the areas upon which embankments are to be placed, construction of dikes, and placing and compacting approved material within roadway areas including holes, pits, and other depressions within the roadway area. Only approved materials shall be used in the construction of embankments and fills. All sod, vegetable and other organic matter, stumps, and roots shall be removed from the surface upon which the embankment is to be placed per Section 201. Unless a thickness is otherwise specified in the Contract, the upper 4 inches of the ground surface will be considered topsoil and shall be removed per Section 207 before placement of embankment fill. The cleared surface shall be completely broken up by plowing or scarifying to a minimum depth of 8 inches or as specified in the Contract, the moisture content increased or decreased as necessary, and compacted to the specified embankment density for the material type present. When embankment is placed on a slope that is steeper than 4H:1 V, as measured in the steepest direction, the existing slope shall be benched as the embankment is placed in layers. A 2 -foot deep key shall be excavated at the base of the existing slope and backfilled with approved and compacted material. The embankment shall be placed in layers from that key. Each horizontal cut shall begin at the intersection of the original ground and the vertical sides of the previous bench. Excavated material from benching may be placed and compacted with the embankment material at the Contractor's expense. During the course of construction, embankment side slopes shall be built a minimum of 12 inches wider than the final grade indicated in the Contract to allow for compaction equipment to compact the full width of the embankment. Once the specified level of compaction is achieved, the side slopes shall be trimmed back to final grade. Excess material placement and removal to satisfy this requirement shall be at the Contractor's expense. If embankment can be placed on only one side of structures such as retaining walls, abutments, wing walls, piers, or culvert headwalls, compaction shall be accomplished without initiating movement or deformation of the structure and without placing excessive pressure against the structure. When noted in the Contract, the fill adjacent to the abutment of a bridge shall not be placed higher than the bottom of the backwall until the superstructure is in place. When embankment is placed on both sides of a concrete wall or box type structure, the embankment shall be brought up equally on both sides of the structure. Where embankment is to be placed and compacted and end dumping is used, the slopes of the original ground or embankment shall be deeply plowed or scarified before starting end dumping. Page 162 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment Embankment fill other than A-1 soil types shall not be placed within standing water, unless otherwise noted in the Contract. During the construction of the embankment, the top surface shall be maintained so that it is well drained at all times. Frozen materials shall not be used in construction of embankments. Frozen material will be identified by the visual observation of ice crystals within the foundation or embankment material, or by measuring the temperature of the ground surface. Subsection 203.07 shall be deleted and replaced with the following: 203.07 Embankment Placement and Compaction Requirements. It is anticipated soil excavated on this project will be placed within the roadway prism or hauled off -site. However, the Engineer and Inspector have the authority to order certain material be placed within the embankment side slopes. Unsuitable excavation materials produced from muck excavation and pipe installation shall not be used for embankment and shall be hauled off the jobsite. Topsoil which has been stripped and stockpiled shall be placed on the top of embankment slopes. Materials incorporated into embankment fill shall be placed and compacted according to the following requirements: (a) Soil Embankment. All soil embankment shall be placed in horizontal layers not to exceed 8 inches in loose lift thickness. Each layer shall be compacted before the placement of subsequent layers. Spreading equipment shall be used to obtain uniform thickness before compaction. As the compaction progresses, continuous mixing, leveling, and manipulating shall be done to assure uniform moisture and density. Additional work involved in drying soil embankment to the required moisture content shall be included in the contract price paid for excavating or furnishing the material with no additional compensation. When conduits (i.e., culverts, pipes, etc.) are installed in embankment material, the embankment shall first be constructed to a required height of a minimum of one foot above the top of conduit and for a distance on each side of the conduit of at least 5 times the diameter or span of the conduit, after which the trench shall be excavated and the conduit installed. Before trench excavation, the embankment material shall pass the compaction requirements for the Project. Soil embankment that is classified as A-1 material may be used to bridge across standing water or swampy ground within the embankment foundation and may be placed in lift thicknesses greater than 8 inches when used for this purpose if approved by the Engineer. A Sheepsfoot compactor shall not be used on A-1 material containing less than 30% retained on the 3h -inch sieve. Per the Western Alliance for Quality Transportation Construction (WAQTC) inspection guidelines, the appropriate equipment to use on granular soils such as an A-1 soil, a steel vibratory roller or pneumatic rubber -tired roller. Sheepsfoot rollers are appropriate for materials composed of cohesive soils and clay rich non -durable bedrock. Soil embankment with less than or equal to 30% retained on the 3/4 -inch sieve shall be tested for compaction using CP-80. Materials classified as AASHTO A-1, A-2-4, A-2-5, and A-3 soils shall be compacted at +/- 2 percent of optimum moisture content (OMC) and to at Page 163 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment least 95 percent of maximum dry density determined per AASHTO T180, modified by CP- 23. All other soil types are compacted to 95 percent of maximum dry density determined per AASHTO T99, modified by CP-23. Soils with 35 percent fines or less are compacted at +/- 2 percent of OMC. Soils with more than 35 percent fines are compacted at a moisture content equal to or above OMC to achieve stability of the compacted lift. Stability is defined as the absence of rutting or pumping as observed by the Contractor's Process Control representative and as approved by the Engineer. If the soils prove to be unstable when compacted at or above optimum moisture content, the moisture content required for compaction may be reduced below OMC as approved by the Engineer. Compaction shall be tested using nuclear density gauges (CP-80-13) at the frequencies specified in Table 106-1. Compaction tests shall be performed in accordance CP-80 and shall utilize 4 one -minute readings. The use of 1 fifteen -second test shall be not acceptable for Process Control testing. Field rock correction tests (CP-23-13) shall be performed at the frequencies specified in Table 106-1 done for each compaction test performed. Rock corrections shall be performed per CP-23. The Process Control tester shall provide their own screen, scale, and hot plate or microwave. A field one -point moisture/density verification test (CP-25-13) shall be performed at the frequency specified in Table 106-1 to verify the use of the correct moisture/density curve. The test sites shall be selected randomly and shall be representative of the materials placed in the surrounding areas. The Contractor shall provide a stable platform on which the one - point tests can be performed. Any time a density verification test is over 100%, a field one point moisture/density verification test and a field rock correction test shall be performed to verify the use of the correct proctor. Before placing any soil embankment with greater than 30 percent retained on the 3/4 -inch sieve, the Contractor shall construct a test strip to the dimensions specified in the Contract or as directed by the Engineer. The test strip may be incorporated into the final embankment. The Contractor shall determine the moisture conditioning necessary to achieve compaction and shall determine the equipment and number of passes necessary to achieve adequate compaction. The Contractor shall use compression -type or vibratory rollers on granular materials and sheepsfoot rollers on cohesive soils. Adequate compaction shall be demonstrated by the absence of rutting, pumping, or deflection following a proof roll of the test strip using any piece of construction equipment that exerts a minimum 18 -kip per axle load. The proof roll will be observed and accepted by the Engineer. Once the test strip passes a proof roll, the Contractor may resume embankment construction using the same moisture conditioning and compaction methods that were used to construct the test strip. Placement, moisture conditioning, and compaction of every lift of soil embankment with greater than 30 percent retained on the 3/4 -inch sieve shall be observed by the Contractor's Page 164 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment Process Control Representative and accepted by the Engineer. Adequate compaction of each lift shall be demonstrated as the absence of rutting, pumping, or deflection as construction equipment is routed over a lift following the compactive efforts that were used and accepted for the respective test strip. The Engineer may request a proof roll at any time to document the condition of a lift. Significant changes in the material being hauled for soil embankment with greater than 30 percent retained on the 3/4 -inch sieve will require construction of a new test strip, and demonstration of adequate compaction methods using a proof roll. Non -durable bedrock shall be watered to promote slaking and break down and pulverized or processed to a maximum particle size of 6 inches. These materials shall be placed and compacted as soil embankment except they shall be compacted with a heavy tamping foot roller weighing at least 30 tons. Each tamping foot shall protrude from the drum a minimum of 4 inches. Each embankment layer shall receive a minimum of four passes with the tamping foot roller. The roller shall be operated at a uniform speed not exceeding 3 miles per hour. No additional compensation will be made for additional roller passes to achieve specified density requirements. Non -durable Bedrock shall not be used to bridge over standing water or swampy ground within an embankment foundation. Non -durable bedrock shall also not be placed within 2 feet of the final subgrade elevation. (b) Rock Embankment and Rock Fill. Rock embankment shall be placed in horizontal layers not to exceed 8 inches in loose lift thickness. The lift thickness can be increased when bridging over standing water or swampy ground in the embankment foundation as directed by the Engineer. Each layer shall be compacted before the placement of subsequent layers. Spreading equipment shall be used to obtain uniform thickness before compaction. Rock fill shall be placed in horizontal layers not to exceed a loose lift thickness equivalent to the average particle size up to a maximum permitted lift thickness of 18 inches. Particles with a maximum dimension of 36 inches are permitted; however, rocks larger than the lift thickness shall be separated enough to allow compaction equipment to operate in between. Material shall be placed to fill in voids between larger stones with finer particle sizes and to avoid nesting. Spreading equipment shall be used to obtain uniform thickness before compaction. If the use of leveling equipment is not practical, the Engineer may permit rock fill material to be cast or end dumped. In such cases sufficient hand or machine work will be required to construct a compact, stable fill and to finish the slopes to a neat and smooth appearance. Rock fill shall not be placed within 2 feet of the final subgrade elevation. When a rock fill is placed over any structure, the structure shall be covered with a minimum of 2 feet of compacted soil embankment or rock embankment material before the rock fill is placed. Page 165 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment The Contractor shall determine the moisture conditioning necessary to achieve compaction for rock embankment or rock fill. Vibratory or compression -type rollers shall be used to compact these materials. At a minimum, compression -type rollers weighing 20 tons shall complete four passes over the entire width of a lift at a speed not to exceed 3 miles per hour. Vibratory rollers shall exert a minimum dynamic force of 30,000 pounds of impact per vibration and achieve a minimum 1,000 vibrations per minute. Vibratory rollers shall complete a minimum of four passes over the entire width of a lift at a speed not to exceed 1.5 miles per hour. Before placing rock embankment or rock fill, the Contractor shall construct a test strip to the dimensions specified in the Contract, or as directed by the Engineer. The test strip may be incorporated into the final embankment. Adequate compaction of the rock embankment or rock fill test strip shall be demonstrated by the absence of rutting, pumping, or deflection following a proof roll of the test strip using any piece of construction equipment that exerts a minimum 18 -kip per axle load. The proof roll will be observed and accepted by the Engineer. Once the test strip passes a proof roll, the Contractor can resume rock embankment or rock fill construction with the same moisture conditioning and compaction methods as the test strip was constructed. Placement, moisture conditioning, and compaction of every lift of rock embankment and rock fill shall be observed by the Contractor's Process Control Representative and accepted by the Engineer. Adequate compaction of each lift shall be demonstrated as the absence of rutting, pumping, or deflection as construction equipment is routed over a lift following the compactive efforts that were used and accepted for the respective test strip. The Engineer may request a proof roll at any time to document the condition of a lift. Significant changes in the characteristics of material being hauled for rock embankment or rock fill will require construction of a new test strip, and demonstration of adequate compaction methods using a proof roll. If the Contractor wishes to deviate from the minimum equipment and compactive efforts specified above for rock embankment or rock fill, the Contractor must first demonstrate the adequacy of the proposed methods with a test strip and passing proof roll. In addition, proof rolls are required for every lift placed for the first 2,000 cubic yards of rock embankment or rock fill placed. The proof rolls used to demonstrate adequate compaction of the first 2,000 cubic yards placed will not be measured and paid for separately but shall be performed at the Contractor's expense. (c) Use of Recycled Concrete and Asphalt. Recycled concrete and asphalt may be incorporated into embankment material, and shall be processed, placed, and compacted per subsection 203.07(a) or (b), depending on the overall classification of the embankment material once the recycled material is incorporated. Rebar shall not extend more than one inch beyond the edges of recycled concrete particles. Recycled concrete or asphalt shall not be placed in the Page 166 of 292 December 18, 2024 Revision of Section 203 — Excavation and Embankment u pper 2 feet of the final subgrade elevation or within 2 feet of the final finished side slopes u nless otherwise noted in the Contract. S ubsection 203.08 shall be deleted and replaced with the following: 203.08 Proof Rolling. Proof rolling with pneumatic tire equipment shall be performed using a minimum axle load of 18 kips per axle. A weigh ticket from an approved scale shall be furnished by the Contractor to substantiate this weight. Contractor's verified proof rolling equipment, meeting the 18 kip loading per axle, shall be available onsite during all phases of earthwork activities and as an erosion control method for dust control mitigation. A current certified scale ticket showing the fully loaded weight of the water truck(s) shall be submitted to the Engineer before any proof roll is performed for acceptance. The Engineer may require a proof roll at any elevation to verify stability. The subgrade shall be proof rolled after the required compaction has been obtained and the subgrade has been shaped to the required cross section. The proof roller shall be operated in a systematic manner so that a record may be readily kept of the area tested and the working time required for the testing. Areas that are observed to have soft spots in the subgrade, where deflection is not uniform or is excessive as determined by the Engineer, shall be ripped, scarified, dried or wetted as necessary, and recompacted to the requirements for density and moisture at the Contractor's expense. After replacement and re - compaction, these areas shall be proof rolled again and all failures again corrected at the Contractor's expense. The repair may involve muck excavation, geogrid reinforcement, replacement of excavated materials, or other methods as directed by the Engineer. After the subgrade has been stabilized, the Contractor shall perform proof rolling per subsection 203.08. Final proof rolling will take place a maximum of two days (48 hours) after all mechanical stabilization or unbound aggregate work has been completed, unless otherwise approved by the Engineer. Final proof rolling will take place a minimum of two days after all lime or other chemical stabilization work has been completed, unless otherwise approved by the Engineer. The finished surface shall be smooth and uniform conforming to the typical sections. Variation from the subgrade plan elevations shall not exceed 0.04 feet. All irregularities, depressions, or weak spots which develop shall be corrected at the Contractor's expense. The surface shall be maintained in a smooth condition, free from undulations and ruts until other work is placed thereon or the work is accepted. No separate payment will be made for areas of unsuitable material excavation, geogrid reinforcement, or replacement of excavated materials.

The original cross -sections will be used for determination of volumes of excavated material removed unless changes have been directed. These measurements will include authorized excavation of rock, shale, or other unsuitable material. All accepted stripping will be measured in stockpiled locations by cross -sectioning. When the excavation conforms to the staked lines and grades, the original cross -sections and the staked sections shall be used for the determination of volumes excavated. Volumes will be computed from the cross -sections by the average end area or other acceptable method. When topsoil or wetland topsoil is included as a separate pay item and is specified, the measured volume of excavation will be reduced by the volume of topsoil or wetland topsoil removed from the area shown as excavation in the Contract. The disposal of unsuitable material and replacement of embankment will not be measured and paid for separately but shall be included in the work. Geogrid and geotextile used in areas where unsuitable materials were removed and replaced with backfill material will not be measured and paid for separately but shall be incidental to the cost of the backfill material.

This work consists of constructing, installing, maintaining, and removing when required, control measures during the life of the Contract to prevent or minimize erosion, sedimentation, and pollution of any State waters as defined in subsection 101. Stormwater runoff from all disturbed areas and soil storage areas for which permanent or interim stabilization is not implemented, must flow to at least one control measure to minimize sediment in the discharge. This shall be accomplished through filtering, settling, or straining. The control measure shall be selected, designed, installed, and adequately sized in accordance with good engineering, hydrologic, and pollution control practices. The control measures shall contain or filter flows in order to prevent the bypass of flows without treatment and shall be appropriate for stormwater runoff from disturbed areas and for the expected flow rate, duration, and flow conditions (i.e., sheet or concentrated flow). The Contractor shall coordinate the construction and maintenance of temporary control measures with the construction of permanent control measures to assure economical, effective, and continuous erosion and sediment control throughout the construction period. The Initial Condition, Interim Condition, and Permanent Condition SWMP drawings are included with the plans for this project. The control measures shown on the Initial Condition and Interim Condition drawings shall be installed in a phased manner prior to the beginning of construction activities within various areas of the limits of construction. The Contractor shall be responsible for preparing and submitting an Erosion Control Phasing Plan which shows how the erosion and sediment control measures will be implemented to the Engineer for approval. Installation of the erosion control measures shall not begin until the Engineer has provided a written approval of the Erosion Control Phasing Plan.

Findings not in compliance with these Specifications shall be documented by the SWMP Administrator on Form 1176 during weekly and post -storm water quality control inspections, routine SWMP audits, or observation by the Engineer. The Engineer will immediately notify the Contractor of each incident of failure to perform erosion control in accordance with any water quality standards, specifications, including items (1) through (9) above by issuing a Form 105. Findings shall be corrected but no longer than 24 hours, to minimize the discharge of pollutants. Failure by the Contractor to clarify a finding location with the Engineer shall not be grounds for correcting the issue with the 24 -hour timeframe. (a) Definitions. 1. Deferment. A request from the Contractor to the Engineer to delay implementation of corrective actions for Regular Findings pertaining to Water Quality Specifications and/or the CDPS-SCP. Deferments may only be granted due to extraordinary circumstances. However, it is at the Engineer's discretion to approve or reject these requests. 2. Finding. An incident discovered through inspection by the Department, the Contractor's SWMP Administrator/Erosion Control Inspector, or by Engineer observation, which is noncompliant with the Water Quality Specifications as specified in 208.09(a)(7) and/or the CDPS-SCP. A Finding will be classified as one of the following: A. Regular Finding. A situation upon inspection that is in noncompliance with the Water Quality Specifications. Maintenance issues identified on the weekly or post -storm Form 1176 shall be considered a regular finding. Page 198 of 292 December 18, 2024 Revision of Section 208 - Erosion Control (Under 1 Acre Disturbance) B. Severe Finding. A discharge outside the project's Limits of Construction (LOC), subsection 107.25(a), to State waters or to a live inlet where the pollutant cannot be reclaimed. C. Chronic Finding. A Chronic Finding is assessed when the same Regular Finding at the same location is documented twice in the last three water quality control inspections. Engineer observed findings outside these inspections will not apply. 3. Inspection Form 105. The Form 105 issued by the Engineer documenting findings from water quality inspections per subsection 208.03(c), approved deferments and other items requiring recordkeeping in compliance with the Water Quality Specifications. 4. Location. The place where the finding was observed; can be a document (e.g., stormwater management plan [SWMP]) or physical location. A physical location must be described with enough detail to guide an independent party to the spot of the finding. Physical locations must be supported with at least one photograph. 5. Recalcitrance. Contractor has shown willful negligence or misrepresentation or unwillingness to adhere to the Water Quality Specifications. 6. Water Quality Specifications. Subsection 107.25, Sections 208, 213 and 216, and Standard Plans M-208-1 and M-216-1. 7. Immediately. For the purposes of this section, immediately shall mean by the end of the construction day. (b) Liquidated Damages and Stop Work Orders. The Contractor will be charged liquidated damages for each finding in the amounts identified below after the 24 -hour period. has expired and one or more of the findings remains uncorrected. Liquidated damages associated with the findings pertaining to this subsection do not indemnify the Contractor of other Liquidated Damages associated with this project. Liquidated damages will not be considered a penalty but shall be considered the estimated additional construction costs incurred due to the delay in correcting the identified findings. Liquidated damages will accumulate for each day that each identified finding that remains uncorrected. The number of days for which liquidated damages are assessed will be cumulative for the duration of the project; that is: the damages for a particular day will be added to the total number of days for which liquidated damages are accumulated on the project. Liquidated damages will be deducted from any monies due to the Contractor on each monthly payment application. Findings are closed when the corrective action is complete, reported to the Engineer and accepted by the Engineer. The Engineer will notify the Contractor when the corrective Page 199 of 292 December 18, 2024 Revision of Section 208 — Erosion Control (Under 1 Acre Disturbance) action is accepted or denied. Liquidated damages will be assessed by the type of finding as follows and will continue until the corrective action is approved by the Engineer. (1) Regular Finding. The time required to repair a Regular Finding shall at the conclusion of the SWMP inspection. The correction of a Regular Finding shall begin as soon as possible, immediately in most cases but not more than 24 hours from the time of the finding. The Engineer shall issue a Form 105 informing the Contractor of the finding and the need for correction to occur. If a finding cannot be immediately corrected, the Contractor shall request a deferment per Section 208.09(c). The Engineer will issue a Form 105 notifying the Contractor that Liquidated Damages are accruing at $1,500 per day per finding for each full or partial calendar day a Regular Finding remains uncorrected after 24 hours from discovery. Each uncorrected or undeferred Regular Finding will be assessed as recalcitrant and the Engineer will issue a project -wide stop work order if the Regular Finding is not addressed within 48 hours after the SWMP inspection has concluded. The Contractor shall fix each recalcitrant finding and submit a plan to avoid future instances of each recalcitrance to the Engineer for approval. The recalcitrance plan shall be in writing, signed by the Contractor and shall include: A. A description of each Recalcitrant Finding. B. Why the corrective action for each Recalcitrant Finding was not implemented within 2 days. C. How the Contractor will avoid future recalcitrance. The Engineer will discuss the recalcitrance plan and may meet with the Superintendent to recommend modifications, if needed. The Engineer will issue a Form 105 accepting or rejecting the recalcitrance plan within 24 hours of the Contractor submitting a plan or resubmitting a modified plan. The Contractor will neither be reimbursed for costs incurred to fix each Recalcitrant Finding pertaining to a control measure in the SWMP plan nor costs to prepare the recalcitrance plan. The Contractor shall propose additional control measures, if needed, according to subsection 208.04(a). The project -wide Stop Work Order and Liquidated Damages will be assessed until approval of the corrective action for each Recalcitrant Finding and approval of the Contractor's recalcitrance plan by the Engineer is given. After written approval by the Engineer, the project -wide Stop Work Order will be lifted, and accrual of Liquidated Damages will cease. If the Contractor fails to perform corrective work by the second day from discovery, the County shall have the option of utilizing a third -party to complete the corrective work. The Contractor shall be responsible for reimbursing the County the cost of utilizing a third -party to complete the corrective work. The cost Page 200 of 292 December 18, 2024 Revision of Section 208 - Erosion Control (Under 1 Acre Disturbance) for utilizing a third -party to complete the corrective work will be deducted from the month's pay application. If only the retainage release pay application is left to close out the project, the cost of corrective work will be deducted from the retainage release payment. If the retainage release payment does not cover the cost of the corrective work, the Contractor will be invoiced for the outstanding balance. The project acceptance and warranty period will not start until the Contractor has reimbursed the County for the entire cost of the corrective work. Failure by the Contractor to perform corrective work shall be grounds for withholding progress payments. Liquidated damages to the Contractor will continue to accrue until the corrective work has been completed. (2) Severe Finding. In response to a Severe Finding, the Engineer will issue a Form 105 and immediately assess Liquidated Damages of $3,500 per Severe Finding. Severe Findings shall be eligible for the 24 -hour grace period (subsection 208.09(b)(1)). Liquidated damages will accrue at $3,500 per Severe Finding per calendar day beginning at the time of discovery of the Severe Finding. A. If the Severe Finding is a discharge to State waters, the Contractor shall prevent any further discharge and shall reclaim discharge which has not yet entered State waters. The Contractor shall report the discharge to CDPHE in accordance with CDPS-SCP requirements. B. If the Severe Finding is a discharge outside the LOC that does not enter State waters, the Contractor shall fully reclaim the discharge before it enters State waters and implement relevant CDPS-SCP noncompliance notification procedures. The Engineer may require the Contractor to submit a plan for permanent stabilization of disturbed areas outside the LOC per 208.04(e)(4) for approval. Permanent stabilization plans pertaining to Severe Findings and subsequent stabilization activities are not subject to 208.09(b). The Contractor shall not be reimbursed for activities undertaken to reclaim the discharge, stabilize areas outside the LOC and implement relevant CDPS-SCP noncompliance notification procedures. If the Contractor fails to perform corrective work immediately upon discovery, the County shall have the option of utilizing a third -party to complete the corrective work. Liquidated damages to the Contractor will continue to accrue until the corrective work has been completed. The Contractor shall be responsible for reimbursing the County the cost of utilizing a third -party to complete the corrective work. The cost for utilizing a third -party to complete the corrective work will be deducted from the month's pay application. If only the retainage release pay application is left to close out the project, the cost of corrective work will be Page 201 of 292 December 18, 2024 Revision of Section 208 — Erosion Control (Under 1 Acre Disturbance) deducted from the retainage release payment. If the retainage release payment does not cover the cost of the corrective work, the Contractor will be invoiced for the outstanding balance. The project acceptance and warranty period will not start until the Contractor has reimbursed the County for the entire cost of the corrective work. Failure by the Contractor to perform corrective work shall be grounds for withholding progress payments. Liquidated damages to the Contractor will continue to accrue until the corrective work has been completed. (3) Chronic Finding. In response to a Chronic Finding, the Engineer will issue a Form 105 and immediately assess Liquidated Damages of $1,500 per Chronic Finding. Chronic Findings shall be immediately corrected. Liquidated damages will accrue at $1,500 per Chronic Finding per day beginning upon discovery of the Chronic Finding. When the Chronic Finding is comprised of two Severe Findings, the Engineer will assess Liquidated Damages in accordance with this specification. If the Contractor fails to perform corrective work immediately upon but not more than 24 hours from discovery, the County shall have the option of utilizing a third -party to complete the corrective work. Liquidated damages to the Contractor will continue to accrue until the corrective work has been completed. The Contractor shall be responsible for reimbursing the County the cost of utilizing a third -party to complete the corrective work. The cost for utilizing a third -party to complete the corrective work will be deducted from the month's pay application. If only the retainage release pay application is left to close out the project, the cost of corrective work will be deducted from the retainage release payment. If the retainage release payment does not cover the cost of the corrective work, the Contractor will be invoiced for the outstanding balance. The project acceptance and warranty period will not start until the Contractor has reimbursed the County for the entire cost of the corrective work. Failure by the Contractor to perform corrective work shall be grounds for withholding progress payments. (4) SWMP Notebook Deficiencies. The SWMP Notebook shall be kept up to date with all SWMP requirements of the Water Quality Specifications and CDPS-SCP. SWMP deficiencies shall result in a pay reduction of $300 per incident that the SWMP Notebook is out of date by more than one week. Corrective actions shall be initialed and dated immediately upon completion and the Compliance Certification signed by the ECI, Superintendent and Engineer, or liquidated damages will be assessed. Page 202 of 292 December 18, 2024 Revision of Section 208 — Erosion Control (Under 1 Acre Disturbance) The Engineer shall document the pay reduction with a Form 105 which shall be signed by the Contractor. The pay reduction shall be deducted from the amount owed to the Contractor for the pay period in which the pay reduction occurred. If the findings are not corrected with 48 hours after discovery, in addition to Liquidated Damages, the Contractor will be subject to a project -wide Stop Work Order for recalcitrance and the Engineer may, in writing, issue a Stop Work Order for Chronic and Severe Findings in accordance with Section 105. A Stop Work Order shall not result in the stopping of the Contract Time. Issuance of a Stop Work Order shall not be considered a valid reason for the Contractor asking for additional Contract Time. Work shall not resume until the Engineer has approved a written corrective action plan submitted by the Contractor that includes measures to prevent future violations and a schedule for the correction of the findings. When a failure meets any one of the following conditions, the Engineer will immediately issue a Stop Work Order in accordance with Section 105 irrespective of any other available remedy: (1) It may endanger health or the environment. (2) It consists of a spill or discharge of hazardous substances or oil which may cause pollution of the waters of the state. (3) It consists of a discharge which may cause a violation of water quality standards. (c) Deferment. If the Contractor seeks deferment because a regular finding cannot be corrected immediately upon discovery, the Superintendent shall submit a deferment request to the Engineer immediately after the issuance of the Form 105. Chronic and Severe Findings are not eligible for deferment. The deferment request shall be in writing, signed by the Superintendent and shall include: 1. Description of Regular Findings to be deferred; 2. The reasons why the Findings cannot be corrected in twenty-four hours; 3. An action plan containing: A. Methodology to protect water quality until each deferred Finding is corrected and accepted; B. Milestones to measure progress toward completion; C. Additional control measures to be implemented until each deferred Finding is corrected and accepted; Page 203 of 292 December 18, 2024 Revision of Section 208 — Erosion Control (Under 1 Acre Disturbance) D. Corrective completion dates for each Finding. Deferments will not be accepted or approved due to the Contractor's operational error, improperly installed control measures, inadequate control measures, lack of preventative maintenance, careless or improper operation, or other non -proactive reason. Note: If an alternative control measure is implemented to correct a Regular Finding, a deferment is not necessary. All modifications to the plan shall be documented in the SWMP. The Engineer will discuss the deferment request and may meet with the Superintendent to recommend modifications to the action plan within 48 hours of the receipt of the deferment request. The Engineer will issue a Form 105 accepting or rejecting the deferment request. The Department will not accept a deferment for operational error, improperly installed control measures, inadequate control measures, lack of preventative maintenance, careless or improper operation, or other non -proactive reason. Preparation of deferment documentation and additional materials, including additional control measures, required to complete the action plan shall be at the Contractor's expense. Time frames noted in subsection 208.09(b)(1) will not be stopped during the deferment review period, therefore, Liquidated Damages will be assessed beginning per the timeframes outlined above if the deferment request is rejected and, furthermore, a rejected deferment plan (subsection 208.09(c)) shall not absolve the Contractor from recalcitrance. The Engineer will assess Liquidated Damages in the amount of $1,500 per calendar day, and partial day, for each uncorrected Deferred Finding that is not completed within the deferment period. These Liquidated Damages will start retroactively to the day the finding was originally noted on the Form 105. (d) Conflict Resolution. Subsections 105.22, 105.23, and 105.24 detail the process through which the parties (Weld County and the Contractor) agree to resolve any issue that may result in a dispute. (e) Exemptions. The Engineer will exempt from subsection 208.09(b) situations of Compliance Assistance, Documented Upset Conditions, Documented Reportable Spills and Documented Winter Exemptions. Release from subsection 208.09(b) does not exempt the Contractor from compliance with CDPS-SCP. 1. Documented Upset Condition. The Contractor shall report, both verbally and in writing, the Upset Condition to CDPHE per CDPS-SCP Part II.L.6 and subsection 208.03(c) and provide written documentation to the Engineer.

Roll, rake and remove ridges and fill depressions, as required to meet finish grades. Limit fine grading to areas that can be planted within 24 hours after fine grading has been completed. No additional payment will be made if the Contractor has to complete fine grading or for fine grading more than one time. 2. Fertilizer, Compost, and Elemental Sulfur. The Contractor shall uniformly apply compost and elemental sulfur on the surface of the topsoil using an agricultural spreader at the rate outlined in above. All competitive, non-native vegetation shall be uprooted and hauled offsite before spreading amendments. If SWMP Site Maps are not included in the Contract, the Contractor shall use the Grading or Roadway plan sheets. When compost and elemental sulfur is required, the Contractor shall homogenously incorporate the compost and elemental sulfur into the top 6 inches of topsoil. Tillage of the amendments shall be completed using a disc and harrow, field cultivator, vibra- shank, or other method suitable to site conditions. For small areas tillage shall be completed using rotary tillers. No measurable depth of organic amendment shall be present on the surface. The shanks on the back of a grader or dozer shall not be used for tillage. Tillage may take multiple passes to achieve the desired harmonious incorporation. If multiple passes are required, the Contractor shall cross till the soil with the second pass occurring at a 30 -degree angle to the first pass. On slope areas, all tillage shall be parallel to the contour. For projects that will utilize aggregate or recycled asphalt shouldering material amendments, tillage is not required under shouldering material. Projects seeding up to the edge of pavement, tillage is not required for first 12" from the edge of pavement. When fertilizers are required, the Contractor shall uniformly apply fertilizer on the surface of the topsoil using an agricultural spreader and then work it into the soil to a depth of four inches (4") with a disc, spring tooth harrow or other suitable equipment. When HGM is required, the HGM shall be mixed in the tank following the procedures outlined below: A. Fill tank with water to a level where the paddles are 1/4 covered and may be activated. B. Activate the mechanical agitation system. Page 225 of 292 December 18, 2024 Revision of Section 212 - Seeding, Fertilizer, Soil Conditioner, and Sodding C. Prime pump and any discharge hoses before adding any HGMs. D. Add the appropriate amount and type of soil stabilizer and tackifier as recommended for the site -specific application. Allow soil stabilizer and tackifier and water to mix for 5 minutes before adding HGMs. See manufacturer application rate chart for amounts of specific Soil Stabilizer & Tackifier and HGMs. E. Continue filling tank with water to approximately 3/4 full and begin adding bags of HGMs. F. All quantity of HGMs should be added before the water level reaches 85% of the tank's capacity. G. Add seed and/or other amendments to slurry as required. H. Completely fill tank with water and allow slurry to mix for a minimum of 5 minutes or until all HGMs are mixed into a consistent slurry. 3.

Page 226 of 292 December 18, 2024 Revision of Section 212 - Seeding, Fertilizer, Soil Conditioner, and Sodding B. Count the number of drill rows (N) on the seeder. C. On drill seeders that the tire drives the seeding mechanism, measure the tire circumference (C) in feet. D. Calculate the number of rotations the tire will complete per acre using the following equation: A = one acre or 43,560 square feet (SF) A /W = feet (F) the drill seeder needs to travel for each acre F/C = number of rotations (R) of the tire per acre E. Reduce the amount of tire rotations by one tenth. .90R = # Tire rotations to calibrate seeder (RCS) F. Find the seeding rate (LBS PLS / Acre) on the Stormwater Management Plan G. Using the information from the seed tag, convert the PLS seed rate to a bulk seeding rate using the following equations: 13/0 PLS = CY° purity (in decimal form) from seed label) x (3/0 germination (in decimal form) from seed label) (LBS PLS / Acre) from the SWMP / % PLS = Required bulk seed per acre in LBS H. Reduce the required bulk seed per acre based on the number of seeder tubes. Required bulk seed per acre / N = Weight in LBS of bulk seed from one tube I. Reduce the required bulk seed rate from the tube by one tenth. 0.90 x Weight of bulk seed from one tube = Collected bulk seed weight (CBS) in LBS J. Set the drill seeder to the correct seeding rate using the manufacturer's recommendation. K. With the collection cup under one tube and the driving wheel jacked up, rotate the tire the RCS amount of times. Use the value stem to count the rotations. L. Using the scale, weigh the seed in the collection cup. Page 227 of 292 December 18, 2024 Revision of Section 212 - Seeding, Fertilizer, Soil Conditioner, and Sodding M. Adjust the drill calibration until the weight of bulk seed in the collection cup equals the CBS in LBS. 5. Biotic Soil Amendment, Fertilizer, Humate, Mycorrhizae and Seed.

The Contractor shall submit the following to the Engineer: 1. A proposed hot mix asphalt mix design prepared per Colorado Procedure 52, including a proposed job -mix gradation for each mixture required by the Contract which shall be wholly within the Master Range Table in subsection 703.04 before the tolerances shown in Section 401 are applied. The weight of lime shall be included in the total weight of the material passing the 75 µm (No. 200) sieve. 2. The name of the refinery supplying the asphalt cement and the source of the anti - stripping additive. 3. A sufficient quantity of each aggregate for the Department to perform the tests specified in Section 3.2.1 of CP 52. 4. The job -mix formula for pavement shall be established by a testing laboratory approved by the County and at the Contractor's expense. Copies of all test data shall be provided to and approved by the County before construction. The Contractor's proposed job -mix formula for each hot mix asphalt grading will be tested by the Department utilizing materials actually produced and stockpiled for use on the project. The job -mix formula for each mixture shall establish a single percentage of aggregate passing each required sieve size, a single percentage of asphalt cement to be added to the aggregate, and a single temperature for the mixture at the discharge point of the plant. When Laboratory tests indicate that a proposed job -mix formula complies with the specifications as revised for the project, a Form 43 shall be executed between the Engineer and the Contractor to establish the job -mix formula. After the Form 43 is executed, and all materials are available on the project, the Contractor shall notify the Engineer a minimum of one working day in advance of beginning production of the hot mix asphalt. Any changes in the Form 43 will require the same notification unless otherwise approved by the Engineer. Subsection 401.02(c) shall be added immediately following Subsection 401.02(b): (c) Reclaimed Asphalt Pavement (RAP) Mixes Furnished to the Project. RAP is allowed in hot mix asphalt (HMA) up to a maximum binder replacement of 20 percent, provided all Page 243 of 292 December 18, 2024 Revision of Section 401 — Plant Mix Pavements - General specifications for HMA are met. Fine Aggregate Angularity requirements shall apply only to the virgin fraction of the fine aggregate. The RAP shall not contain clay balls, vegetable matter, or other deleterious substances, and must meet the uniformity requirements as outlined below. HMA Project Verification Testing for asphalt content and gradation will be performed at the frequencies listed in the Field Materials Manual per CP-L 5120. The Contractor shall have an approved mix design for the amount of RAP to be used. The AC content of the RAP utilized in the Contractor RAP mix design shall be the average AC content determined per 1B or 1C, below, or alternatively, a minimum of five samples of the Contractor's RAP stockpile may be sampled and the average AC content of the RAP be determined using AASHTO T-164, Method A or B, or per 1C below. The Contractor shall determine the total binder replaced by the binder in the RAP pursuant to the following equation: Total Binder Replaced = (A x B) x 100/E Where: A = RAP % Binder Content* B= RAP %in Mix* E = Total Effective Binder Content* * in decimal format (i.e., 2% is 0.02) The Total Binder Replaced by the binder in the RAP shall not exceed 20 percent of the effective binder content of either the mix design or the produced mix. The use of RAP shall be controlled per subsections 105.05 and 106.05. If the Contractor elects to use RAP, the following additional conditions shall apply: 1. The Contractor shall have an approved Process Control (PC) Plan that details how the RAP will be processed and controlled. The PC plan shall address the following: A. RAP Processing Techniques. This requires a schematic diagram and narrative that explains the processing (crushing, screening, and rejecting) and stockpile operation for this specific project. B. Control of RAP Asphalt Binder Content (AASHTO T-164, Method A or B). RAP Asphalt Binder Content may also be determined per CP-L 5120, provided a RAP AC content correction factor is determined through correlation testing with AASHTO T-164, Method A or B. The correction Page 244 of 292 December 18, 2024 Revision of Section 401 — Plant Mix Pavements - General factor shall be determined by performing correlation testing on the first five samples of the RAP AC content, then at a frequency of one for every five AC content tests thereafter. The correction factor shall be determined by calculating the average difference in AC content between CP-L 5120 and AASHTO T-164, Method A or B, and applying the correction to the AC content determined per CP-L 5120. Frequency: 1/1,000 tons of processed RAP material (minimum five tests) C. Alternative Control of RAP Binder Content. The Contractor may propose a RAP asphalt content correction factor to be used in conjunction with CP-L 5120. The proposed CP-L 5120 RAP asphalt content correction factor shall be used with all RAP asphalt contents tested for the mixture design and quality control sampling and testing. The methodology of the proposed CP- L 5120 RAP asphalt content correction factor shall be outlined in detail in the approved RAP PC Plan. At a minimum, the proposed CP-L 5120 correction factor shall identify the principal source locations of the RAP aggregate, gradation of the material tested, and specific ignition oven serial number used in all the RAP asphalt content testing. The RAP source locations, material gradation, and specific equipment used shall substantiate the CP-L 5120 asphalt content correction factor used for the testing. The substantiation must be from data gathered from historical information or specific asphalt content correction data obtained from tests performed on similar virgin aggregate sources, virgin material gradations, and the specific equipment used. D. Control of RAP Gradation (CP31 or AASHTO T-30): Frequency: 1/1,000 tons of processed RAP material (minimum three tests) E.

If RAP millings generated are incorporated in the same project, per CPL 5145 the Contractor shall pave with a virgin mix design until sufficient amount of processed RAP has been stockpiled and tested to allow full production of a RAP HMA mix. Subsection 401.10, eighth paragraph shall be deleted and replaced with the following: (1) Blaw-Knox asphalt pavers manufactured prior to 2007 shall be equipped with the Blaw- Knox Materials Management Kit (MMK). (2) Cedarapids asphalt pavers shall be those that were manufactured in 1989 or later. (3) Caterpillar asphalt pavers shall be equipped with deflector plates as identified in the December 2000 Service Magazine entitled "New Asphalt Deflector Kit {6630, 6631, 6640}". Subsection 401.12 shall be deleted and replaced with the following: 401.12 Surface Conditioning. After the roadbed has been graded and compacted, the subgrade shall be trimmed to the correct elevation (+/- 0.04 feet) and cross section as shown on the plans. The surface of the base course shall be checked with a GPS Rover or other approved device. The surface shall be verified by the Contractor and the Engineer before the application of any pavement. The variation of the surface from the plan surface elevation for base course shall not exceed 0.04 feet (1/2 inch). High areas shall be trimmed to the proper elevation. Low areas shall be filled with base course material and compacted to a condition similar to that of the surrounding grade. The finished grade shall be maintained in a smooth and compacted condition until the pavement is placed. All irregularities exceeding the specified tolerance shall be corrected to the satisfaction of the Engineer at no additional cost to the Department. Only blades with machine control capable of finishing the base grade to within the specified tolerance shall be allowed. A trimming machine shall not be used to achieve final grade unless Page 246 of 292 December 18, 2024 Revision of Section 401 — Plant Mix Pavements - General written approval is obtained from the Engineer. If a trimming machine is approved for use, it shall be machined controlled. The trimmer machine shall not change the trimming's approved proctor for the aggregate base course material by more than 6 lbs/cubic foot. If it does, the trimmings shall not be allowed to be placed within the roadway prism. Before placing tack coat and beginning overlay work, the surface to be tack coated shall be swept to remove accumulations of loose gravel and debris. Asphalt plant mix shall be placed only on properly constructed surfaces that are free from substances that would adversely affect the pavement quality. Contact surfaces of curbing, gutters, manholes, and other structures shall be painted with a uniform coating of asphalt cement before placing asphalt mixture against them. S ubsection 401.17 shall be deleted and replaced with the following: 401.17 Compaction. The hot mix asphalt shall be compacted by rolling. Both steel wheel and pneumatic tire rollers will be required. The number, weight, and type of rollers furnished shall be sufficient to obtain the required density while the mixture is in a workable condition. Compaction shall begin immediately after the mixture is placed and be continuous until the required density is obtained. When the mixture contains unmodified asphalt cement (PG 58-28 or PG 64-22) or modified (PG 58-34), and the surface temperature falls below 185 °F, further compaction effort shall not be applied unless approved, provided the Contractor can demonstrate that there is no damage to the finished mat. If the mixture contains modified asphalt cement (PG 76-28, PG 70- 28 or PG 64-28) and the surface temperature falls below 230 °F, further compaction effort shall not be applied unless approved, provided the Contractor can demonstrate that there is no damage to the finished mat. If the Contractor can demonstrate to Weld County that all the manufacturer's recommendations were followed and the pneumatic tire roller is detrimental to the finished surface of the HMA, the Contractor may request Weld County to waive the pneumatic tire roller requirement. P neumatic tire rollers shall not be used on SMA pavement. Steel wheel rollers shall not be used in vibratory mode when compacting HMA or SMA on bridge decks. Warm Mix Asphalt compaction requirements shall conform to CP 59. All roller marks shall be removed with the finish rolling. Use of vibratory rollers with the vibrator on will not be permitted during surface course final rolling and will not be permitted on any rolling on bridge decks covered with waterproofing membrane. S MA shall be compacted to a density of 93 to 98 percent of the daily theoretical maximum specific gravity, determined according to CP 51. All other HMA shall be compacted to a density of 92 to 98 percent of the daily theoretical maximum specific gravity, determined according to CP 51. If more than one theoretical maximum specific gravity test is taken in a day, the average Page 247 of 292 December 18, 2024 Revision of Section 401 — Plant Mix Pavements - General of the theoretical maximum specific gravity results will be used to determine the percent compaction. Field density determinations will be made per CP 44 or 81. The longitudinal joints shall be compacted to a target density of 90 to 98 percent of the theoretical maximum specific gravity. The theoretical maximum specific gravity used to determine the joint density will be the average of the daily theoretical maximum specific gravities for the material that was placed on either side of the joint. Density (percent relative compaction) will be determined per CP 44. The Contractor shall obtain one 6 -inch diameter core at a random location within each longitudinal joint sampling section for determination of the joint density. The Contractor shall mark and drill the cores at the location directed by the Engineer and in the presence of the Engineer. The Engineer will take possession of the cores for testing. The Contractor may take additional cores at his own expense. Coring locations shall be centered on the visible line where the joint between the two adjacent lifts abuts the surface. The center of all joint cores shall be within 1 inch of this visible joint line. Core holes shall be repaired by the Contractor using materials and methods approved by the Engineer. PC and OA joint coring shall be completed within five calendar days of joint construction. Longitudinal joint coring applies to all pavement layers. When constructing joints in an echelon paving process, the joints shall be clearly marked to ensure consistent coring location. In small areas, such as intersections, where the Engineer prescribes paving and phasing methods, the Engineer may temporarily waive the requirement for joint density testing. Incentive or disincentive payment determined for joint density per subsection 105.05 will apply to the HMA on each side of the joint. If a layer of pavement has joints constructed on both sides, incentive or disincentive payment for each of those joints will apply to one half of the pavement between the joints. Along forms, curbs, headers, walls, and all other places not accessible to the rollers, the mixture shall be thoroughly compacted with mechanical tampers. Any mixture that becomes loose and broken, mixed with dirt, or is in any way defective, shall be immediately removed and replaced with fresh hot mixture, and compacted to conform to the surrounding area. The Contractor shall construct a compaction pavement test section (CTS) for each job mix for which 2,000 or more tons are required for the project. The CTS will be used to evaluate the number of rollers and the most effective combination of rollers and rolling patterns for achieving the specified densities. Factors to be considered include, but are not limited to, the following: (1) Number, size, and type of rollers. (2) Amplitude, frequency, size, and speed of vibratory rollers. (3) Size, speed, and tire pressure of rubber tire rollers. Page 248 of 292 December 18, 2024 Revision of Section 401 — Plant Mix Pavements - General (4) Temperature of mixture being compacted. (5) Roller patterns. The CTS shall be constructed according to the following procedures: The CTS shall be constructed to provide the nominal layer thickness specified. The first 500 tons of hot mix asphalt on the project location shall constitute the CTS. The production and placement rates of the CTS shall closely approximate the anticipated production and placement rates for the remainder of the Contract. Compaction of the CTS shall commence immediately after the hot mix asphalt has been spread and shall be continuous and uniform over the entire CTS. For the CTS, compaction shall continue until no discernible increase in density is obtained by additional compactive efforts. All compaction shall be completed before the surface temperature of the mixture drops below 185 °F. Approved types of rollers shall be used to achieve the specified density. The Contractor shall determine what methods and procedures are to be used for the compaction operation. The compaction methods and procedures shall be used uniformly over the entire last 200 tons. The Contractor shall record the following information and a copy of this data shall be furnished to the Engineer. (1) Type, size, amplitude, frequency, and speed of roller. (2) Tire pressure for rubber tire rollers, and whether the pass for vibratory rollers is vibratory or static. (3) Surface temperature of mixture behind the laydown machine and subsequent temperatures and densities after each roller pass. (4) Sequence and distance from laydown machine for each roller, and number of passes of each roller to obtain specified density. Two sets of random cores shall be taken within the last 200 tons of the CTS. Each set shall consist of seven random cores. The Engineer will determine the coring locations using a stratified random sampling process. The locations of these cores will be such that one set can serve as a duplicate of the other. One set of these cores shall be immediately submitted to the Engineer. This set will be used for determining acceptance of the CTS and determining density correction factors for nuclear density equipment. Densities of the random samples will be determined by cores according to CP 44. Density correction factors for nuclear density equipment will be determined according to CP 81. Coring shall be performed under Weld County observation. Coring will not be measured and paid for separately but shall be included in the work. For SMA, a CTS is not used. The Contractor shall follow the requirements for the demonstration control strip per the Revision of Section 403, Stone Matrix Asphalt Pavement. Page 249 of 292 December 18, 2024 Revision of Section 401 — Plant Mix Pavements - General The CTS meets requirements if the Quality Level of the random samples is greater than or equal to 75. The Quality Level will be determined according to CP 71. Once constructed and accepted, the CTS shall remain in place and become part of the hot mix asphalt on the project. When the Quality level is less than 75 the Contractor shall construct an additional test section, utilizing different rollers, or roller positions, or roller patterns as required. A written proposal detailing the changes in methods and procedures that will be used to obtain density is to be submitted to the Engineer for review before constructing the additional test section. If the Quality Level of a CTS is less than 75 and greater than or equal to 44, the Engineer may accept the material at a reduced price per Section 105. If the Quality Level of a CTS is less than 44, the Engineer may: (1) Require complete removal and replacement with specification material at the Contractor's expense. (2) Where the finished product is found to be capable of performing the intended purpose and the value of the finished product is not affected, as determined by the Engineer, permit the Contractor to leave the material in place with a pay factor, but not more than 75 percent of the bid price. Each CTS shall be 500 tons. If in -place densities of the CTS, as determined by nuclear density equipment before determining density of the cores, meet the CTS density requirements, the Contractor may begin production paving and continue to place hot mix asphalt pavement under the following conditions: (1) The period during which the Contractor continues to pave without test results from cores shall not exceed one workday. (2) Construction proceeds at the Contractor's risk. If correlation with the cores reveals that the densities do not meet the CTS requirements, the hot mix asphalt pavement placed subsequently will be subject to price reduction or removal and replacement. After production paving work has begun, a new Roller Pattern shall be demonstrated when a change in the compaction process is implemented. All additional costs associated with construction of the CTS shall be at the Contractor's expense. The hot mix asphalt placed in the CTS will be paid for per subsection 401.22, at the contract price for the hot mix asphalt. If the Contractor requests changes to the roller pattern that was established during the CTS, the Contractor must perform a Roller Pass Study to demonstrate that the specified density is obtained with the new roller pattern before proceeding with the paving operation with Engineer Approval. Page 250 of 292 December 18, 2024 Revision of Section 401 — Plant Mix Pavements - General All hot mix asphalt (HMA) materials or work will be evaluated for conformity to the Contract per subsection 105.05 except HMA that is used for patching and temporary pavement. The Contractor shall determine the necessary roller compaction process needed to produce a target pavement density of 94.0 percent of the average daily theoretical maximum specific gravity (RICE) values per Colorado Procedure 44 Method B. During the first day of production, three stratified random locations will be selected by the Department. At each location, a minimum of three 4 -inch diameter cores shall be taken by the Contractor within an 18 -square foot area of pavement. The Department will take possession of the set of three cores from each location and determine the intermediate percent relative compaction for each core. Each set of three cores will be averaged to produce the percent compaction for each location. A minimum of three locations will be used to measure the percent compaction of the first day of production. All coring shall be completed by the Contractor and submitted to the Department. Full production of the thin lift shall not begin until the required project compaction process is successfully established by the Contractor and approved by the Engineer. The approved compaction process shall be used for the duration of the thin lift paving. Changes to the thin lift mixture shall require a new roller compaction process. During production, density tests shall be taken at a frequency of one set of three cores per 500 tons of HMA placed. Each 4 -inch diameter core in the set shall be taken by the Contractor within an 18 -square foot area of pavement at each stratified random location. The Department will take possession of a set of three cores from each location to determine the intermediate percent compaction for each core. Each set of three cores will be averaged to produce the percent compaction for each location. The Contractor will be immediately notified when the Department locates areas of in -place density less than 89.8 percent of average RICE for the material. The actual area of pavement to be removed full width and replaced will be determined by the Contractor, taking one 4 -inch diameter exploratory core at 50 -foot intervals or less in each direction from the affected location until two successive locations are found in each direction which are greater than 90.9 percent of the average RICE for the material.

End of Section Page 258 of 292 December 18, 2024 Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements Section 420 of the Standard Specifications is hereby revised for this project as follows: Subsection 420.01 shall be revised to include the following: This work includes furnishing and installing geosynthetic material over unsuitable subgrade materials per these specifications and the details shown on the plans. Subsection 420.06, paragraph 1 shall be deleted and replaced with the following: 420.06 Erosion Control and Drainage. Geotextiles for erosion control or drainage shall be loosely laid (not stretched) with the roll direction the same as the anticipated water flow, and in a manner that avoids any rupture of the cloth. Geotextiles used for erosion control or drainage shall meet the requirements of subsection 712.08 and Tables 712-2a and 712-2b. Geotextile (Drainage)(Class 1) shall be placed under all riprap as shown on the plans or as directed by the Engineer. Subsection 420.07 shall be deleted and replaced with the following: 420.07 Geotextile Separator. Geotextiles used as separators shall meet the requirements of subsection 712.08 and Tables 712-a and 712-2b. The geotextile separator shall be installed per the following: (a) Subgrade Preparation: Clear, grub and excavate (as required) to the plan subgrade or undercut elevation, stripping topsoil, deleterious debris and unsuitable material from the site. Cut stumps and other projecting vegetation as close and even to the ground surface as practical. Specialized equipment with low ground pressure, as directed by the Engineer, shall be required for very soft soils to minimize subgrade disturbance. The surface of the subgrade shall be relatively smooth and level, and depressions or humps greater than 6 inches shall be graded out. (b) Geotextile Deployment: The geotextile material shall be placed directly on the prepared subgrade. The geotextile shall be placed by machinery or by hand labor. The geotextile shall not be dragged across the subgrade. The geotextile shall be unrolled in the direction of travel so the machine direction (i.e., long axis) of the roll is parallel with channelized traffic patterns. The geotextile shall be rolled out flat and tight with no folds or wrinkles. Wrinkles and folds in the geotextile (not associated with roadway curves) shall be removed by stretching and staking as required. The geotextile may be held in place before the placement of the aggregate base course or other cover material by pins, staples, or piles of fill or rock. On curves, the geotextile may be folded to conform to the curve or by cutting the roll to match the curve. Page 259 of 292 December 18, 2024 Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements Adjacent rolls shall be overlapped along their sides and ends as a function of subgrade strength per Table 420-1. Table 420-1 — Minimum Required Overlap Subgrade Value Strength R- Overlap Width (Inches) of Unsewn Seam 5-10 30 10-20 24 > 20 18 If 30 inches of overlap is required, the overlap shall be sewn or otherwise adhered to limit the potential formation of a slip plane between the overlapped panels. Sewn seams shall be per the manufacturer's recommendations. Overlap the geotextile in the direction that fill will be spread to avoid peeling -back of the geotextile at overlaps by the advancing fill. Cut and overlap the geotextile to accommodate curves. The geotextile shall be cut using sharp shears, razor knives or handheld power (i.e., "cutoff") saws. The geotextile shall be cut to conform to immovable protrusions, such as manhole covers and vertical utilities. Overlap lengths will not be paid for separately but will be considered subsidiary to item 420. (c) Fill Placement: Before covering the geotextile separator with fill materials, the condition of the geotextile shall be inspected by the Engineer to determine that no holes, rips or other defects exist. If any defects are observed, the section of the geotextile containing the defect shall be repaired by placing a new layer of geotextile extending beyond the defect in all directions a minimum distance equal to the overlap shown in Table 420-1. Alternatively, the defective section may be replaced. See subsection 420.07(e). The first lift of cover material shall be end -dumped or spread over the geotextile from the edges of the geotextile. The height of the dumped pile shall be limited to avoid local bearing capacity failures. The first lift of cover material shall be graded to a 12 -inch thickness or to top of grade whichever is less and compacted. Equipment shall not be on the treated area with less than the minimum thickness of compacted cover material over the geotextile. Small dozer equipment or front-end loader shall be used to spread the cover material. Construction vehicles shall be limited in size and weight such that rutting in the initial lift is no deeper than 3 inches. If rut depths exceed 3 inches, the Contractor shall use a smaller size and weight of construction vehicles. Ruts shall be filled in with cover material. Construction equipment shall not travel over the exposed geotextile at speeds of more than 5 mph. Construction equipment shall not make turns on the first lift of cover material. Construction vehicles can dump aggregate fill as they advance, provided the construction traffic does not cause significant rutting upon bare subgrade. Sudden braking, sudden starting and sharp turning shall be avoided. Tracked construction equipment shall not be operated directly upon the exposed geotextile. Page 260 of 292 December 18, 2024 Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements A minimum aggregate fill thickness of 6 inches is required before operation of tracked equipment on the geotextile. In addition, turning of tracked equipment shall be kept to a minimum to prevent tracks from displacing the fill and damaging the geosynthetic. On softer subgrade materials, aggregate fill shall be end -dumped from the edge of the previously placed material, spreading from the middle outward. (d) Compaction: Standard compaction methods shall be used to obtain the required compaction for the fill materials. The compaction tests shall be done per the requirements that are outlined elsewhere in the Specifications. (e) Installation and Repairs for Damaged Areas: Repairs to geotextiles shall be made in the field by placing a repair panel or patch over the damaged area. The repair panel shall extend a minimum of 3 feet beyond the edges of the damaged geotextile. Geotextile that is damaged after placement shall be removed and replaced at the Contractor's expense. Subsection 420.09 shall be revised to include the following: Geotextile (Separator) will be measured in place by the square yard of surface area, completed and accepted. Subsection 420.10 shall be revised to include the following: Payment will be made under: Pay Item Pay Unit Geotextile(Reinforcement)(Tensar InterAx NX 650) Square Yard Square Yard Geotextile Separator (Mirafi FW-300)(Contingency) Geotextile (Drainage)(Class 1) will not be measured and paid for separately but shall be included in work for the riprap pay item. Payment will be full compensation for all work and materials required to complete the item. Overlap and waste for geomembrane, geotextile, and geotextile materials will not be measured and paid for separately but shall be included in the work. Page 261 of 292 December 18, 2024 Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements Geogrid Reinforcement for Roadway Embankment Description 420.11. This work consists of furnishing and installing geogrid reinforcement material, in accordance with these specifications and in conformity with the lines and grades shown on the plans or established. Materials 420.12. Geogrid is a polymer grid structure specifically fabricated for use as a soil reinforcement. Geogrid reinforcement material shall conform to the following: Table 420-2 Geogrid Reinforcement Properties Physical Properties Unit Characteristic Values Roll Length 1 262.5 or 328 Feet Roll Width 1 12.5 or 15.5 Feet Roll Weight1 lb 189 or 292 Mass per Unit Areal oz/sq yd 8.27 Continuous Parallel Rib Pitch inch 3.2 Rib Aspect Ratio3 >1.0 Node Thickness2 Inch 0.13 Color Identification White/Black/White Table Notes: 1 Unless indicated otherwise, values shown are minimum average roll values determined in accordance with ASTM D4759-02. 2 Nominal dimensions. 3 Ratio of the mid -rib depth to the mid -rib width. The minimum overlap of the geogrid reinforcement shall be 18 inches. The geogrid reinforcement shall manufactured from a coextruded, composite polymer sheet, which is then punched and oriented. The resulting structure shall consist of continuous and on - continuous ribs forming three aperture geometries (hexagon, trapezoid, and triangle) and an unimpeded suspended hexagon. The geogrid reinforcement shall contain stabilizers or inhibitors to prevent degradation of properties due to ultraviolet light exposure. The geogrid reinforcement shall be inert to all naturally occurring alkaline and acidic soil conditions. The manufacturer shall furnish certified test reports from an independent laboratory indicating that the material meets the requirements of the specification. For example, Tensar InterAx NX650 geogrid or an approved equivalent meets or exceeds the specifications outlined in Table 420-2. Page 262 of 292 December 18, 2024 Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements Construction Requirements 420.13. Geogrid reinforcement shall be installed in accordance with the following: (a) Delivery, Storage, and Handling. Upon delivery, the Contractor shall check the geogrid to assure the proper material has been received. The geogrid material shall be in roll form with each roll individual identified. Rolls shall be stored in a manner that prevents excessive mud, wet concrete, epoxy, or other deleterious materials from coming in contact with and affixing to the geogrid. Rolls may be stored horizontally in stacks not to exceed five rolls high. Special care shall be taken in the handling of geogrids manufactured from polypropylene at temperatures at or below -14°F. Rolls shall not be stored in temperatures below -20°F. Rolls may be stored uncovered for up to 6 months in direct exposure to sunlight without any loss in certifiable structural properties. (b) Site Preparation. Clear, grub and excavate (if necessary) to the design subgrade elevation, stripping topsoil, deleterious debris and unsuitable material from the site. Smooth grade and compact the soils using appropriate compaction equipment. Grade or crown the surface for positive drainage away from the construction zone. (c) Geogrid Installation. Geogrid shall be laid at the proper elevation and alignment as shown on the plans or as directed by the Engineer. Geogrid shall be oriented such that the roll length runs parallel with traffic patterns. Place the rolls of geogrid in position, cut the roll bands and manually unroll the material over the subgrade. Unroll the geogrid in the direction of travel so that the long axis of the roll is parallel with channelized traffic patterns. Overlap adjacent rolls along their sides and ends per the manufacturer's recommendations. Care shall be taken to ensure that geogrid sections do not separate at overlaps during construction. Overlap the geogrid in a shingle pattern in the direction that fill placement will be spread to avoid "peeling" of geogrid at overlaps by the advancing fill. Weaker subgrades that are easily rutted with conventional construction traffic shall require an "end -dumping" operation. Adjacent geogrid rolls shall be mechanically connected to one another per the manufacturer's recommendations. Cut and overlap the geogrid to accommodate curves. Cutting may be done with sharp shears, a knife -like implement or handheld power (i.e., "cutoff") saws. Cut grid to conform to manhole covers and other immovable protrusions. Do not allow excessive buckling of the geogrid. Page 263 of 292 December 18, 2024 Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements Geogrid rolls exhibit "roll memory" where the product may roll back upon cutting or reaching the end of the roll. The installer shall take appropriate measures to ensure that the product lies flat during fill placement. Geogrid material shall be secured to the ground surface by placement of loose fill at the corners and edges or as directed by the Engineer. The geogrid material may also be anchored in place to maintain overlaps and alignment over the coverage area. Before fully unrolling the geogrid, the center and the corners of the roll's edge shall be secured. (d) Dumping and Spreading Aggregate Fill: At least 6 inches of fill material is required for the initial lift thickness of aggregate fill over geogrids. However, for very soft conditions, a significantly thicker fill layer will be required to prevent rutting and/or bearing capacity failure of the underlying subgrade. Fill material shall be back -dumped from trucks riding on top of the reinforced fill and bladed onto the geogrid in such a manner that the fill rolls onto the grid ahead, e.g., by gradually raising dozer blade while moving forward. Standard, highway -legal, rubber -tired trucks (end dumps and belly dumps) may drive over the geogrid at very slow speeds (less than 5 mph) and dump aggregate fill as they advance. This construction traffic shall not cause rutting upon bare subgrade. Turns and sudden starts and stops shall be avoided. On softer subgrades, it may be necessary to back trucks up and dump fill upon previously placed fill. Caution shall be taken to avoid overstressing the subgrade soil both during and after fill placement. Tracked equipment shall not be driven directly on the geogrid. A minimum of 6 inches of aggregate fill (or required minimum design fill thickness) shall be spread between the geogrid and tracked equipment . On softer subgrades, a lightweight, low ground pressure (LGP) dozer shall be used to evenly push out the fill over the exposed geogrid. Do not to catch the dozer blade or other equipment on the geogrid. The dozer blade shall be raised gradually as each lift is pushed out over the geogrid. The fill material shall cascade onto the geogrid, rather than being pushed into it. Be aware of geogrid overlaps and advance the aggregate fill with the shingle pattern. (e) Compacting. Material placed over the geogrid shall be compacted in accordance with the compaction requirements for embankment for this project or as directed. Care shall be taken to assure the geogrid is not damaged. To ensure the geogrid is not damaged, rollers shall use static mode instead of vibratory mode. Backfill shall be compacted to 95 percent of the maximum density as determined by AASHTO T-99. The moisture content of the backfill material prior to and during compaction shall be uniformly distributed throughout each layer and shall be within two percent of optimum. Method of Measurement Page 264 of 292 December 18, 2024 Revision of Sections 420 and 712 — Geosynthetics and Geogrid Reinforcements 420.14.

For concrete operations at night, the Contractor shall illuminate the designated concrete truck washout location including the access and the wash out site. (6) Workers on foot, performing work within a moving work space (i.e., striping layout/installation, surveying, etc.) shall wear ANSI approved high visibility apparel and headwear for Class 3 risk exposure including vest, Class E pants or leg gaiters, and reflective tape on hard hats. Workers may use portable lighting that can be worn on the hard hats that provide 360 -degree visibility. (7) Portable light towers and lights mounted on stands shall be sturdy and free-standing without the aid of guy wires or bracing. Minimum illumination levels as stated in (1) above shall be maintained at a distance of 5 feet on all sides of stationary equipment with either equipment mounted or free-standing lights. (8) The Contractor shall ensure that all pieces of equipment have operating lights to illuminate operator's controls, backhoe and loader buckets, and illuminate the equipment reach limits around rotating equipment (i.e., the paving machine shall have illumination for the hopper, auger, and screed areas). (9) The TCS vehicle shall have the rear of the truck illuminated while installing, maintaining, and removing traffic control devices unless sufficient lighting levels exist with stationary lights. (10) The Contractor shall maintain a uniformity ratio no greater than 5:1 over the stationary work space. Uniformity ratio is the ratio of average to minimum horizontal illuminance within the work space. The uniformity ratio shall be determined by dividing the average of all light meter measurements by the light meter measurement at the darkest spot within the illuminated area. 632.06 Night Work Lighting Plan. The Contractor shall submit a lighting plan to the Engineer for review signed by the Contractor's designated person three days in advance of the Page 286 of 292 December 18, 2024 Revision of Section 632 — Night Work Lighting Preconstruction Conference. The lighting plan shall appropriately describe the work and include the following: (1) Layout drawing and supplemental narrative showing light locations, equipment mounted lights, and configuration including both typical spacing and lateral placement for each work activity. (2) Tabulation of lights for those lights that are included within the Night Work Lighting pay item. Lights included in the tabulation such as tower lights, lights mounted on stands and lighting mounted to mobile equipment (not original equipment lights) but those additional equipment mounted lights or portable lights that provide the 20 feet in front and behind illumination zone shall have catalog cuts giving the specific brand names, model numbers, lamp type and wattage. (3) Narrative description of those operations where workers will be on foot in a moving work space. (4) Details of hoods, visors, louvers, shields or other means to be used to minimize glare. The plan shall be revised and updated by the Contractor as requested by the Engineer during the progress of the work to accommodate changes to the work. 632.07 Inspection of Lighting. Lighting inspection by the Engineer will be performed jointly with the Contractor's designated person on a drive through the project to include (1) observation of the lighting setup to evaluate glare potential for drivers and workers and (2) light meter measurements to determine minimum illumination levels. The Contractor shall make adjustments to the lighting as needed based on the Engineer's inspection. In the event of any failure of the lighting system, the Engineer may determine to discontinue work until the required level of illumination is restored. Delays due to insufficient lighting levels are the responsibility of the Contractor. Any corrections and deficiencies needed to provide the minimum illumination levels shall be addressed by the start of the next work shift. The Engineer will take light meter measurements to verify the minimum lighting levels using a light meter provided by the Contractor during the night work shift. Light meter readings will be taken within the work space where work is being performed, in a horizontal plane, light sensor part of the meter held parallel to the ground with the sensor aimed upward, 3 feet above the pavement or ground surface. Meter readings will be taken at the source at 5 -foot intervals out to the illuminated work space perimeter. These measurements will be documented and filed in the project records. 632.08 Lighting for Flagger Stations. For nighttime flagging, flagger stations shall be illuminated by an overhead light source providing a minimum lighting intensity level of 5 -foot candles measured 1 foot out from the flagger's chest. The flagger station light shall illuminate the station area with a radius of at least the width of the lane plus 5 feet, and be centered on the flagger in the initial flagging position. The size of the illuminated area shall be increased to account for flagger movements required to control traffic. The flagger station lighting shall be Page 287 of 292 December 18, 2024 Revision of Section 632 — Night Work Lighting maintained at an adequate height above the pavement and be capable of being shielded through the use of visors, hoods, louvers, or screens as needed to minimize glare to approaching traffic and spilling over onto adjacent properties. Method of Measurement 632.09. Lighting for night work will not be measured but will be paid for as a single lump sum. Basis of Payment 632.10. Payment for lighting as shown on the Night Work Lighting Plan will include all labor, materials, and equipment necessary to complete and maintain the work. Payment for lighting will include portable 360° visibility lighting worn on hard hats. Progress payments will be made based on the lump sum price bid as follows: 20 percent when the Lighting for Night Work Plan has been submitted, accepted, and satisfactory lighting of nighttime operations has begun; the remaining 80 percent will be paid in equal monthly progress payments for the remaining time lighting is required for the night work operations. Payment will be made under: Pay Item Pay Unit Night Work Lighting Lump Sum Flagger station lighting, designated person, light meters, and additional power sources (generator and inverter) will not be measured and paid for separately but shall be included in the work. End of Section Page 288 of 292 December 18, 2024 Traffic Control — General Traffic Control — General The key elements of the Contractor's method of handling traffic (MHT) are outlined in subsection 630.10.

Site Description The Contractor shall comply with all CDOT contractual requirements, and all requirements associated with the CDPS-SCP on this project. The SWMP Administrator for Construction shall update the SWMP plans to reflect current project site conditions. A. Project Site Location: Location or address of construction office: The project location is WCR 37, in Weld County, Colorado. The southern limit of the project is approximately 100 -ft south of WCR 8. The project ends 1000 -ft north of WCR 12 (south of Hwy 52). B. Project Site Description: The project site consists of WCR 37 roadway, within the current Weld County ROW. WCR 37 is an asphalt paved roadway with gravel shoulders. The proposed construction project will consist of a 2" mill of the existing asphalt, followed by a 2"+/- asphalt overlay. The existing width and limits of the roadway will be maintained. This project is being put forth as a maintenance type project since the existing asphalt roadway base will not be disturbed, causing a concern for erosion. The overlay is needed in this area, because it is intended to be used as a detour route for a larger roadway project being done by Weld County in the area. There are no utility relocations or storm drainage improvements designated with this project. C. Proposed Schedule for Sequence for Major Construction Activities: • Install initial erosion control items along WCR 37 as shown on SWMP plan (contractor may adjust erosion control items as required) • Mill asphalt along sections of WCR 37 (contractor may phase milling to keep road open with traffic control/flagging) • Repair soft spots in existing roadway as needed to prepare for final overlay • Provide temporary striping on milled road as needed • Overlay existing roadway and establish aggregate base course (ABC) shouldering • Provide permanent striping • Seed any areas outside of roadway limits that were disturbed during the mill and overlay process • Remove initial erosion control items once site has been stabilized D. Acres of Disturbance: 1. Total area of construction site (LOC SITE AREA): 20.30 acres 2. Total area of proposed disturbance (LDA): 7.99 acres (includes mill and overlay area of roadway - less than 1 -acre of disturbance anticipated outside of roadway limits) 3. Total area of seeding: 0.5 acres 4. Total area of pre -project impervious surface: 305,645 sq. ft. 5. Total area of final impervious surface: 323,356 sq. ft. E. Existing Soil Data: Soil types for the project area have been determined using the NRCS Soil Survey Website. The site is listed as hydrological Type A, designated as Valent Sand and Vona Loamy Sand with slopes ranging from 0% to 9%. The soil erosivity K -Factor ranges from 0.02 to 0.24 for the site. Data Source(s): Natural Resources Conservation Soil Survey website. 2. Stormwater Management Controls for First Construction Activities The Contractor shall perform the following A. Potential Pollutants Sources: Refer to Potential Pollutant Sources in SWMP Section 4A.

Being a Grid Bearing of the Colorado State Coordinate System North Zone, North American Datum 1983/2011, with all other bearings contained herein relative thereto. BASIS OF ELEVATION: Project is based on NAVD 88 elevation of 4893.90, NGS designation: "U 260", a bench mark disc set in concrete structure, stamped "U 260 RESET", in the Southwest one —quarter of Section 29, Township 2 North, Range 66 West, Sixth P.M., All other Control Point elevations on this project are based on GPS observations. COORDINATE DATUM: Project coordinates are modified Colorado State Plane North Zone (0501) NAD 83(2011) coordinates. The combined elevation/scale factor used to modify the coordinates is 0.99972568. Project coordinates are truncated by 1,000,000 in the Northing and 3,000,000 in the Easting. The CHARN is based on NAD 83(2011) datum.

Addendum Acknowledgement ***A signed copy must be submitted with your bid. Thank you!*** Company Name: Date of Signature Signature: Name: Title: Addendum #1 Date: January 9, 2025 1. Contractor Questions and Responses Question 1: How will asphalt patching limits be determined? Answer 1: Areas requiring patching will be specified by the Engineer or Inspector on a case -by -case basis based on field observation. The Engineer or Inspector will look for general areas of concern ahead of milling, and then mark the limits of the specific areas following milling. Proof rolling is anticipated. Input from the Contractor will be welcomed during this process; however, the Engineer or Inspector will make the final determination on patching limits. Question 2: Will hand work be required for the asphalt patching? Answer 2: Yes, it should be anticipated that some patching areas will require hand work. During marking of asphalt patching limits, however, Weld County will strive to provide a minimum patching width of 8 feet so that a paver can be utilized in as many HMA patch areas as possible. The bid schedule and Section 403 of the Project Special Provisions is also being modified with Addendum #1 to separate HMA patching that can be placed with a paver, versus HMA patching that must be placed by hand. Question 3: Will HMA acceptance be based on gradation? Answer 3: Yes, the HMA acceptance testing for this project shall be the gradation testing procedures per the CDOT Field Materials Manual as stated in Section 403.01 of the Revision of Section 403. Question 4: Are the asphalt millings being kept by Weld County, or will the Contractor keep the millings? Answer 4: All asphalt removals (millings and chunks) will be the property of the Contractor for this project. The Construction Plan Set has been revised and attached to Addendum 1 for clarification, and it now coincides with the Revision of Section 202 Project Special Provision.

Site Description The Contractor shall comply with all CDOT contractual requirements, and all requirements associated with the CDPS-SCP on this project. The SWMP Administrator for Construction shall update the SWMP plans to reflect current project site conditions. A. Project Site Location: Location or address of construction office: The project location is WCR 37, in Weld County, Colorado. The southern limit of the project is approximately 100 -ft south of WCR 8. The project ends 1000 -ft north of WCR 12 (south of Hwy 52). B. Project Site Description: The project site consists of WCR 37 roadway, within the current Weld County ROW. WCR 37 is an asphalt paved roadway with gravel shoulders. The proposed construction project will consist of a 2" mill of the existing asphalt, followed by a 2"+/- asphalt overlay. The existing width and limits of the roadway will be maintained. This project is being put forth as a maintenance type project since the existing asphalt roadway base will not be disturbed, causing a concern for erosion. The overlay is needed in this area, because it is intended to be used as a detour route for a larger roadway project being done by Weld County in the area. There are no utility relocations or storm drainage improvements designated with this project. C. Proposed Schedule for Sequence for Major Construction Activities: • Install initial erosion control items along WCR 37 as shown on SWMP plan (contractor may adjust erosion control items as required) • Mill asphalt along sections of WCR 37 (contractor may phase milling to keep road open with traffic control/flagging) • Repair soft spots in existing roadway as needed to prepare for final overlay • Provide temporary striping on milled road as needed • Overlay existing roadway and establish aggregate base course (ABC) shouldering • Provide permanent striping • Seed any areas outside of roadway limits that were disturbed during the mill and overlay process • Remove initial erosion control items once site has been stabilized D. Acres of Disturbance: 1. Total area of construction site (LOC SITE AREA): 20.30 acres 2. Total area of proposed disturbance (LDA): 7.99 acres (includes mill and overlay area of roadway - less than 1 -acre of disturbance anticipated outside of roadway limits) 3. Total area of seeding: 0.5 acres 4. Total area of pre -project impervious surface: 305,645 sq. ft. 5. Total area of final impervious surface: 323,356 sq. ft. E. Existing Soil Data: Soil types for the project area have been determined using the NRCS Soil Survey Website. The site is listed as hydrological Type A, designated as Valent Sand and Vona Loamy Sand with slopes ranging from 0% to 9%. The soil erosivity K -Factor ranges from 0.02 to 0.24 for the site. Data Source(s): Natural Resources Conservation Soil Survey website. 2. Stormwater Management Controls for First Construction Activities The Contractor shall perform the following A. Potential Pollutants Sources: Refer to Potential Pollutant Sources in SWMP Section 4A. The SWMP Administrator for Construction shall prepare a list of all potential pollutants and their locations in accordance with subsection 107.25. B. Offsite Drainage Run on Water): Place Control Measures to address run-on water in accordance with subsection 208.03. C. Vehicle Tracking Control: Control Measures shall be implemented in accordance with subsection 208.04.

Perimeter Control: Perimeter control shall be established as the first item on the SWMP to prevent the potential for pollutants leaving the construction site boundaries, entering the stormwater drainage system, or discharging to state waters.

Being a Grid Bearing of the Colorado State Coordinate System North Zone, North American Datum 1983/2011, with all other bearings contained herein relative thereto. BASIS OF ELEVATION: Project is based on NAVD 88 elevation of 4893.90, NGS designation: "U 260", a bench mark disc set in concrete structure, stamped "U 260 RESET", in the Southwest one —quarter of Section 29, Township 2 North, Range 66 West, Sixth P.M., All other Control Point elevations on this project are based on GPS observations. COORDINATE DATUM: Project coordinates are modified Colorado State Plane North Zone (0501) NAD 83(2011) coordinates. The combined elevation/scale factor used to modify the coordinates is 0.99972568. Project coordinates are truncated by 1,000,000 in the Northing and 3,000,000 in the Easting. The CHARN is based on NAD 83(2011) datum. Project coordinates Northing US Survey Feet = (State Plane Coordinate Northing X 1.000274395 — 1,000,000).

Five (5) contractors submitted proposals (Coulson Excavating Company, Inc., Martin Marietta Materials, Inc., Asphalt Specialties Company, Inc., Brannan Sand and Gravel Company, LLC, and Colorado Paving Inc.). The Public Works and Purchasing Departments reviewed the submitted proposals in accordance with the Best Value procurement method outlined in Chapter 5, Article IV, Sec. 5-4-40. Following initial review by Public Works staff and coordination with the Purchasing Department, four (4) of the 5 proposals were determined to be unresponsive but Coulson Excavating Company, Inc. (Coulson) remains in consideration. A review team consisting of 5 Public Works staff members has reviewed and scored the Coulson proposal based on all scoring criteria, and Coulson received a total score of 249.50 out of 300. Please refer to the review score summary below. Review Score Summary Contractor Technical (out Total Score of 250) Schedule (out Score Total of 20) (out Total Score Cost of 30) bout RFP Total Score of 300) Cost Coulson Excavating Inc. 199.50 20.00 30.00 249.50 $1,792,229.25 Company, The Engineer's Estimate for the project was $2,328,028.75. Coulson's proposal indicates they can meet the construction schedule while completing the project for $1,792,229.25 (about 23% less than the Engineer's Estimate). In addition, Coulson has provided good responses to the questions included in the solicitation, strong recent example projects, and has completed quality work for Weld County in the past. Therefore, Public Works recommends awarding the contract to Coulson Excavating Company, Inc. for an amount not to exceed $1,792,229.25. Per the bid documents, construction is anticipated to start on or around April 3, 2025 and be completed no later than May 30, 2025. Public Works has budgeted for this project in its 2025 budget.
