PASS -AROUND REVIEW PASS -AROUND TITLE: CR 66 and CR 41 Intersection Project — Bid Award DEPARTMENT: Public Works PERSON REQUESTING: Clay Kimmi, Jay McDonald, Curtis Hall, Don Dunker DATE: October 21, 2022 Brief description of the problem/issue: On July 14, 2022, the BOCC approved a pass around allowing Public Works to use the Best Value bidding process that is outlined in Chapter 5, Article 5-4-40 of the Weld County Code. The Request for Qualifications (RFQ) for the CR 66 and CR 41 Intersection Project was advertised on July 29. Three RFQs were received on August 15. Public Works and Purchasing reviewed the RFQs and shortlisted 2 of the 3 bidders on August 22. The shortlisted bidders were provided the Request For Proposal (RFP) on August 29. The bidders provided their proposals including costs on September 26. Following the review of the proposals, the bidders were invited to an interview with the review committee to present their project approach and answer questions that the County had regarding the proposals and bids. The interviews were held on October 5. After the interviews, it was apparent to the County that several items in the bid needed to be further clarified. As a result, it was decided to proceed to the Best and Final Option (BAFO) phase of the bidding process. The items needing more information were clarified and the bidders were given the opportunity to revise their bids to account for the new information. The bids from the BAFO were opened on October 20. The scoring process used in the selection of the bidder representing the best value to the County is summarized in the attached documents. The bidder's proposals were reviewed using 5 different weighted categories representing a maximum of 100 points. The bidder's qualifications, work approach, critical issues, and familiarity with Weld County represent 60% of the RFP score and cost/schedule represents 40% of the RFP score. The interviews were scored using 4 weighted categories representing 100 points. The total number of points available equals 100. The BAFO pricing is substituted back into the scoring matrix to get a new RFP score for the cost/schedule category. The total scores are ranked from high to low with the highest score being assigned a rank of 1. Each reviewer's rank is then summed to get an aggregate ranking. For this project, IHC-Scott was ranked as number 1 by all 5 reviewers for a total score of 5. Structures Inc. was ranked as number 2 by all 5 reviewers for a total score of 10. The bidder with the lowest score represents the best value to the County. The engineer's estimate for the project was $12,667,391.25. IHC-Scott's bid price for the project was $12,821,742.91. Structure Inc's bid price was 12,423,928.93. IHC-Scott was within 1.22% of the engineer's estimate and Structures was within 1.9% of the engineer's estimate. IHC-Scott represents the best value for the County because they plan to provide all the concrete required for the project from their own batch plant which will be less than 1 mile from the project. Having their own plant setup allows IHC-Scott to maintain a high quality of concrete for the project. The use of their own plant also reduces the risk of having schedule delays due to quantity limitations which have plagued contractors throughout 2022. The result of having their own batch plant is shown in IHC-Scott's bid because it is approximately $398,000 higher than Structure Inc's bid. Structures Inc is proposing to haul all the concrete including the concrete required for paving from Martin Marietta's concrete batch plant on CR 13. Structures Inc will not have exclusive use Martin Marietta's batch plant and will be impacted by quantity limitations which have plagued contractors throughout 2022. The quantity limitations at a third party batch plant are not expected to decrease in 2023 due to supply chain issues and the lack of qualified delivery drivers. What options exist for the Board? (include consequences, impacts, costs, etc. of options): 1. The Board can opt to award the construction contract for the CR 66 and CR 41 project to IHC-Scott because they represent the best value to Weld County after all factors are considered. The risk associated with schedule delays is minimized by having a Contractor who can control their production of concrete and is not subject to the quantity limitations of a third party batch plant. 2. The Board can request a work session to further discuss these bids. Recommendation: Public Works recommends Option 1 which is to award the construction contract to IHC-Scott because they represent the best value to the County. Public Works has budgeted money in the 2022 and 2023 budgets to cover awarding the contract to IHC-Scott without asking for a supplemental budget increase. The contract would be done using Notice to Proceed 1 (NPT1) in the amount of $2,000,000 in 2022 and NPT2 in the remaining amount for 2023. Public Works has coordinated with Don Warden and he is in concurrence with our recommendation. rove Schedule R mendation Work Session Other/Comments: Perry L.

Subsection 105.06 shall be revised to include the following: 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. A set of flexural strength beams and splitting tensile strength cylinders shall be taken and tested at 7 days to determine the 7 -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. 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. Liquated damages will be assessed if the project is not completed on time. 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. 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.

Incentive/Disincentive payments will not 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. Subsection 105.06(f) shall be deleted and replaced with the following: (f) When compressive strength is indicated, the Contractor may take cores at his own expense and per Colorado Procedure 65 to provide an alternative determination of strength to replace acceptance test results with a compressive strength less than 4.500 psi. The higher value of the 28 -day compressive strength of acceptance cylinders or the corresponding core's compressive strength will be used for I/DP. When flexural strength is indicated in the Contract. the Contractor shall, in the presence of the Engineer, develop a correlation curve during the laboratory mix design process and during the first week of concrete placement 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. The Lower Tolerance Limit (TO) for flexural strength shall be 600 psi. At any time during production, the Engineer may request a verification of the correlation curve developed during the laboratory mix design phase or the first week of production. 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.

The Contractor shall take penetration measurements every 6 inches across a transect perpendicular to the direction of the tractor and spanning the width of the subgrade soil preparation. Depths of penetration shall confirm that a minimum of 12 inches can be achieved without reaching 300 psi on the rod penetrometer pressure gage (approximately 30 pounds of pressure on the T -handle). Existing subgrade shall be de -compacted to a depth of 14 inches. If multiple passes are needed, the subsequent passes shall be positioned so that the ripping equipment (subsoilers) from the previous pass are split by the subsequent pass. Following ripping, the Contractor shall remove all sticks, stones, debris, clods, and all other substances greater than 6 inches in diameter. The Contractor shall restrict motorized vehicle and foot traffic from passing over the ripped area since this would recompact the areas that received subgrade soil preparation. The first 4 feet from the edge of pavement shall be ripped to a depth of 6 inches. If the project is going to use aggregate base course or recycled asphalt as a shouldering technique, those areas will not require subgrade soil preparation. Depth of soil ripping for the subgrade soil preparation shall be checked with the rod penetrometer. The Contractor shall verify adequate de -compaction of the entire area to have topsoil placed using a rod penetrometer in the presence of the Engineer. Tests shall be performed at a minimum of ten random locations per each acre as selected by the Engineer. The Test shall verify that a depth of 12 inches of penetration into the soil can be achieved without reaching 300 psi on the rod penetrometer pressure gage (approximately 30 pounds of pressure on the T -handle). If this depth cannot be achieved for 80 percent of the penetrations, the Contractor shall re -rip the area at no additional cost to the Department. 207.06 Placement of Topsoil and Seeding Media. Topsoil and Seeding Media shall be hauled and placed at the locations disturbed and will be re -vegetated or as shown on the plans. The contractor shall place a minimum thickness of 6 inches and should only be handled when it is dry enough to work without damaging soil structure. Topsoil and Seeding Media shall be placed a minimum depth of twelve (12) inches when placed over riprap as required on the plans. No Topsoil or Seeding Media shall be placed below ordinary high water mark except as otherwise specified in bio-stabilization bank treatments. Salvaged topsoil placement deeper than 6 inches is allowed if additional approved material is on -site. Contractor shall place topsoil in a method that does not re -compact subgrade material using low ground -contact pressure equipment, or by excavators and/or backhoes operating adjacent to it. The final grade shall be free of all materials greater than 4 inches in diameter within the designed clear zone for the project. Equipment not required for revegetation work will not be permitted in the areas of placed topsoil. Soil amendments, seedbed preparation, and permanent stabilization mulching shall be accomplished within four working days of placing the topsoil on the de -compacted civil subgrades. If placed topsoil is not mulched with permanent stabilization mulch within four working days, the Contractor shall complete interim stabilization methods per subsection 208.04(e), at no additional cost to the Department. Time to perform the work may be extended for delays due to weather. METHOD OF MEASUREMENT 207.07. Topsoil material will be measured by the actual number of cubic yards of topsoil placed and accepted. The volume of topsoil will be determined by measuring the area in which the topsoil is placed and multiplying the area by 0.5 feet. 120 August 29, 2022 6 SECTION 207 TOPSOIL Subgrade soil preparation will be measured by the square yards of subgrade which is ripped and accepted for adequate de -compaction. BASIS OF PAYMENT 207.08. The accepted quantities measured will be paid for at the Contract unit price for each of the pay items listed below that appear in the bid schedule. Payment will be made under: Pay Item Pay Unit Yard Seedino Media Cubic Yard Topsoil (Wetland) Cubic Yard Oiatire.Yard Cubic Yard Stockpile Topsoil Amendments for Topsoil (Onsite) and Seeding Media will not be measured and paid for separately but shall be included in the work.

The SWMP Administrator is equivalent to theCDPS-SCP Qualified Stormwater Manager. (4) Supervisors or foremen of subcontractors working on the project. (5) (Not Used) (6) Weld County design professional who prepared or reviewed the Stormwater Management Plan. 133 August 29, 2022 12 SECTION 208 EROSION CONTROL At this Conference, the attendees shall discuss the SWMP, CDPS-SCP, sensitive habitats on -site, wetlands, other vegetation to be protected, and the enforcement mechanisms for not meeting the requirements of this specification. Per Part I.D.1 of the CDPS-SCP, the required inspection schedules are a minimum frequency and do not affect the Contractor's responsibility to implement control measures in effective operating condition as prescribed in the SWMP. Proper maintenance of the control measures may require more frequent inspections. Site inspections shall start within 7 calendar days of the start of construction activities onsite. The person(s) inspecting the site may be on the Contractor's staff or a third party hired to conduct stormwater inspections under the direction of the Contractor. The Contractor is responsible for ensuring that the inspector meets the definition of a SWMP Administrator. Per Part I.C.2.ix of the CDPS-SCP, the SWMP shall: (i) Document the constraints necessitating an alternative temporary stabilization schedule, provide the alternative stabilization schedule, and identify all locations where the alternative schedule is applicable on the site map. (ii) Describe and locate the methods used to achieve final stabilization of all disturbed areas at the site. (iii) Describe the measures used to establish final stabilization through vegetative cover or alternative stabilization method, and describe and locate any temporary controls measures in place during the process of final stabilization. (iv) Describe and locate any planned permanent control measures to control pollutants in stormwater discharges that will occur after construction operations are completed, including but not limited to, detention/retention ponds, rain gardens, stormwater vaults, etc. Prior to beginning construction, the Contractor shall evaluate the project site for stormwater draining into or through the site. When such drainage is identified, control measures shall be used, if possible, to divert stormwater from running on -site and becoming contaminated with sediment or other pollutants. The diversion may be accomplished with a temporary pipe or other conveyance to prevent water contamination or contact with pollutants. Run-on water that cannot be diverted shall be treated as construction runoff and adequate control measures shall be employed. The SWMP Administrator shall evaluate all non-stormwater coming onto the site, such as springs, seeps, and landscape irrigation return flow. If such flow is identified, control measures shall be used to protect off -site water from becoming contaminated with sediment or other pollutants. The SWMP Administrator shall review existing inlets and culverts to determine if inlet protection is needed due to water flow patterns. Prior to beginning construction, inlets and culverts needing protection shall be protected and the location of the implemented control measure added to the SWMP Site Map. Prior to construction, the Contractor shall implement appropriate control measures for protection of wetlands, sensitive habitat, and existing vegetation from ground disturbance and other pollutant sources, per the approved project schedule as described in subsection 208.03(b). When additional control measures are required and approved by the Engineer, the Contractor shall implement the additional control measures and the SWMP Administrator shall record and describe them on the SWMP Site Map. The approved control measures will be measured and paid for per subsections 208.11 and 208.12. 134 August 29, 2022 13 SECTION 208 EROSION CONTROL (a), Project Review.

Topsoil stockpiles shall receive interim stabilization unless specified per Section 207 as a different material than the other disturbed areas on -site. 3. Summer and Winter Stabilization. Summer and winter stabilization is defined as stabilization during months when seeding is not permitted. As soon as the Contractor knows shutdown is to occur, interim stabilization shall be applied to the disturbed area. Protection of the interim stabilization method is required. Reapplication of interim stabilization may be required as directed. 4. Permanent Stabilization. Permanent stabilization is defined as the covering of disturbed areas with topsoil, seeding, mulching with tackifier, soil retention coverings, and such non -erodible methods as permanent pavement or concrete, riprap, road shouldering, etc., or a combination thereof as required by the Contract. Other permanent stabilization techniques may be proposed by the Contractor, in writing, and shall be used if approved in writing by the Engineer. Permanent stabilization requirements shown on the plans shall be completed within four working days of the placement of the topsoil per Section 207. 5. Final Stabilization. Final stabilization is achieved when all ground -disturbing activities at the site have been completed, and uniform perennial vegetative cover has been established with an individual plant density of at least 70 percent of pre -disturbance levels, or equivalent permanent physical erosion reduction methods have been employed. Per Part I.B.1.a.iii.b.3.b and c of the CDPS-SCP, the Contractor shall ensure all temporary control measures are removed from the construction site once final stabilization is achieved, except when the control measure specifications allow the control measure to be left in place (i.e., bio- degradable control measures). Maintenance.

Liquidated damages associated with incidents pertaining to this subsection do not indemnify the Contractor of other Liquidated Damages associated with this project. 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 per subsection 105.01. 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. 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 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. 155 August 29, 2022 34 SECTION 208 EROSION CONTROL 1. Regular Finding. The time required to repair a Regular Finding shall begin at 11:59 PM on the date the Inspection Form 105 is issued. The Contractor shall have no more than a 24 -hour grace period to correct the Regular Finding before Liquidated Damages are assessed. The grace period extends until 11:59 PM on the day after the Inspection Form 105 was issued. 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 the 24 -hour grace period. At 11:59 PM on the 2nd day after the Form 105 was issued, each uncorrected, undeferred Regular Finding will be assessed as recalcitrant and the Engineer will issue a project -wide stop work order. 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: (1) A description of each Recalcitrant Finding. (2) Why the corrective action for each Recalcitrant Finding was not implemented within 2 days. (3) How the Contractor will avoid future recalcitrance.

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 end of the second day, 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 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. 2. Severe Finding. In response to a Severe Finding, the Engineer will issue Inspection Form 105 and immediately assess Liquidated Damages of $3,500 per Severe Finding. Severe Findings shall not be eligible for the twenty -four-hour grace period (subsection 208.09(b)(1)).

The Contractor shall report the discharge to CDPHE per CDPS-SCP requirements. (2) 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 immediately perform corrective work, 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 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. 3. Chronic Finding. In response to a Chronic Finding, the Engineer will issue Inspection Form 105 and immediately assess Liquidated Damages of $1,500 per Chronic Finding. Chronic Findings shall not be eligible for the twenty -four-hour grace period (subsection 208.09(b)). Liquidated damages will accrue at $1,500 per Chronic Finding per day beginning at 11:59 PM of day the Inspection Form 105 is issued. When the Chronic Finding is comprised of two Severe Findings, the Engineer will assess Liquidated Damages per this specification. If the Contractor fails to immediately perform corrective work, 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 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. Deferment. If the Contractor seeks deferment because an erosion control finding cannot be corrected immediately upon discovery, the Superintendent shall submit a deferment request to the Engineer by 11:59 PM of the day after the issuance of Inspection 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 157 August 29, 2022 36 SECTION 208 EROSION CONTROL (2) The reasons why the Findings cannot be corrected in twenty-four hours (3) An action plan containing: (i) Methodology to protect water quality until each deferred Finding is corrected and accepted (ii) Milestones to measure progress toward completion (iii) Additional control measures to be implemented until each deferred Finding is corrected and accepted (iv) 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. The Engineer will issue a Form 105 accepting or rejecting the deferment request by 11:59 PM of the second day after the Inspection Form 105 documenting the Regular Finding is issued. Weld County 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 11:59 PM on calendar day two 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. These Liquidated Damages will start on the date the uncorrected work was deferred to be completed (subsection 208.09)c)(3)). In addition, Liquidated Damages of $1,500 per calendar day will be assessed retroactively to 11:59 PM of the day the finding was originally noted on the Inspection 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.

This work consists of dewatering temporary excavations and constructing temporary diversions required to control groundwater and surface water for the installation of hydrologic structures (e.g., concrete box culvert, ditches, irrigation structures, culverts, etc.). All diversion and dewatering activities shall be performed per Sections 107.25 and 208 of the Specifications. All dewatering activities shall be performed per Colorado Department of Health and Environment dewatering regulations. Contractor is cautioned that the work involves construction in and around irrigation channels and areas of local drainage. These areas are subject to frequent periodic inundation. MATERIALS 211.02. On -site materials may be used within the limits of construction to construct temporary dams and berms. Materials such as plastic sheeting, sand bags, inflatable devices and storm sewer pipe may also be used if desired by Contractor. The Contractor shall provide all required materials and equipment to facilitate dewatering activities. Dewatering shall also include all materials, equipment, erosion/sediment control measures, and personnel required for the treatment of groundwater, surface water, or stormwater that has come into contact with construction materials. CONSTRUCTION REQUIREMENTS 211.03. Requirements for diverting and controlling surface and groundwater during construction are as follows: (a) General. When diverting surface water and/or groundwater through the project area, the Contractor shall ensure that comingling of offsite and onsite water does not occur unless all of the water discharging from the site is treated before releasing it offsite. Irrigation water should be piped through the project, wherever possible, in order to avoid comingling with onsite water and the subsequent treatment of the water before its release offsite. For all excavation, Contractor shall provide suitable equipment and labor to remove water, and shall keep the excavation dewatered so construction can be carried on under dewatered conditions. The Contractor shall dewater, by pumping or by excavating trenches leading to a positive gravity outlet, to a depth of at least three feet below the underside of any permanent structural element including but not limited to footings, cutoff walls, headwalls, etc. before exposing their proposed bearing surfaces. The dewatering process shall be commenced a sufficient amount of time in advance of placing excavation equipment thereon to prevent undue disturbance of the foundation soil. If, in the opinion of the Engineer, equipment is causing undue disturbance, the Engineer may require further drying of the bearing area or place limitations on the type of equipment permitted on the bearing area. The Engineer may require the Contractor to place (at the Contractor's expense) additional filter material beyond any limits that may be shown on the plans to compensate for the loss of bearing capacity. The water level shall be maintained below the level of placed concrete for at least three days before the water level is allowed to rise. The Contractor's method of dewatering and water disposal, including pumping and discharge equipment, must be approved by the Engineer before implementation. The Contractor shall submit a dewatering plan for review and approval 30 calendar days before implementation per Subsection 105.02. Water Disposal shall be per Subsection 107.25 - "Water Quality 165 August 29, 2022 2 REVISION OF SECTION 211 DEWATERING AND DIVERSIONS Control". Contractor shall obtain all necessary permits and submit copies to the Engineer before commencing any dewatering activities. The dewatering plan shall include the following: Copies of all permits required for dewatering, treatment of, and/or disposing of the water; b. Method statement detailing how dewatering activities will be minimized in excavations; c. Method of measuring surface water or groundwater discharge; d. Listing of equipment descriptions including the size, number, type, capacity, and location of equipment during dewatering operations; Methods of testing surface water and groundwater to determine the appropriate disposal methods; f. Detailed methods for water disposal; g. If applicable, name of the facility where contaminated water is to be delivered; and h. Plans and design calculations, sealed and signed by a Professional Engineer licensed in the State of Colorado which support the dewatering plan including but not limited to: 1. Method for determining the design flow; 2. Map showing location of the discharge points; 3. Phasing plans; and 4. Site restoration plans show how the area will returned to its original configuration. Water control shall be accomplished such that no damage is done to adjacent channel banks or structures. Contractor is responsible for investigating and becoming familiar with all site conditions that may affect the work including surface water, potential flooding conditions, level of groundwater and the time of year the work is to be done. All excavations made as part of dewatering operations shall be backfilled with the same type of material as was removed and compacted to ninety five percent (95%) of Maximum Standard Proctor Density (ASTM D698) except where replacement by other materials and/or methods are required. Contractor shall conduct operations in such a manner that storm or other waters may proceed uninterrupted along their existing drainage courses. By submitting a bid, Contractor acknowledges that Contractor has investigated the risk arising from such waters and has prepared his bid accordingly, and assumes all of said risk. At no time during construction shall Contractor affect existing surface or subsurface drainage patterns of adjacent property. Any damage to adjacent property resulting from Contractor's alteration of surface or subsurface drainage patterns shall be repaired by Contractor at no additional cost to the Owner. Contractor shall remove all temporary water control facilities when they are no longer needed or at the completion of the Project. 166 August 29, 2022 3 REVISION OF SECTION 211 DEWATERING AND DIVERSIONS Pumps and generators used for dewatering and water control shall be quiet equipment enclosed in sound deadening devices. (b) Surface Water Control. Surface water control generally falls into the following categories: 1. Normal low flows along the channel 2. Storm/flood flows along the channel 3. Flows from existing storm drain pipelines; and 4. Local surface inflows not conveyed by pipelines Contractor shall coordinate, evaluate, design, construct, and maintain temporary water conveyance systems. These systems shall not worsen flooding, alter major flow paths, or worsen flow characteristics during construction. Contractor is responsible to ensure that any such worsening of flooding does not occur. Contractor is solely responsible for determining the methods and adequacy of water control measures. At a minimum, Contractor shall be responsible for diverting the quantity of surface flow around the construction area so that the excavations will remain free of surface water for the time it takes to install these materials, and the time required for curing of any concrete or grout. Contractor is cautioned that the minimum quantity of water to be diverted is for erosion control and construction purposes and not for general protection of the construction -site. It shall be Contractor 's responsibility to determine the quantity of water which shall be diverted to protect the Work from damage caused by stormwater. Contractor shall, at all times, maintain a flow path for all channels. Temporary structures such as berms, sandbags, pipeline diversions, etc., may be permitted for the control of channel flow, as long as such measures are not a major obstruction to flood flows, do not worsen flooding, or alter historic flow routes. The Contractor's method of diverting the surface water shall be approved by the Engineer before implementation. The Contractor shall submit a diversion plan for review and approval 30 calendar days before implementation per Subsection 105.02. The diversion plan shall include the following: (1) Method statement addressing all requirements including copies of the relevant permits required for stream diversion; and (2) Plans and design calculations, sealed and signed by a Professional Engineer licensed in the State of Colorado, support the diversion plan including but not limited to: Method for determining design flow; b. Surface water profiling and conveyance calculations; c. Phasing Plans; and d. Site restoration plans showing how to return the stream bed to its original configuration as it was before construction. (c) Groundwater Control. Contractor shall install adequate measures to maintain the level of groundwater below the foundation subgrade elevation and maintain sufficient bearing capacity for all structures, pipelines, earthwork, and rock work. Such measures may include, but are not limited to, installation of 167 August 29, 2022 4 REVISION OF SECTION 211 DEWATERING & DIVERSIONS perimeter sub -drains, pumping from drilled holes or by pumping from sumps excavated below the subgrade elevation. Dewatering from within the foundation excavations shall not be allowed. The foundation bearing surfaces are to be kept dewatered and stable until the structures or other types of work are complete and backfilled. Disturbance of foundation subgrade by Contractor operations shall not be considered as originally unsuitable foundation subgrade and shall be repaired at Contractor's expense. Any temporary dewatering trenches or well points shall be restored following dewatering operations to reduce permeability in those areas as approved by Engineer. METHOD OF MEASUREMENT 211.04.

No combination of either shall be used until proven by such studies, except that, if approved in writing and otherwise permitted by these specifications, an accelerator or a retarder may be used without a separate trial mixture study. If the Contractor is manufacturing these mixes and they are not on the CDOT approved mix design list (APL), separate trial mixture studies shall be made for concrete for each placing method (slip form, fixed form, or hand placement) proposed. The temperature of concrete in each trial batch shall be reported. Each mixture shall be designed to promote easy and suitable concrete placement, consolidation and finishing, and to prevent segregation and excessive bleeding. (3) Mixture Proportioning for Flexural Strength The following step-by-step procedure shall be followed: 1. Fabricate all beams and cylinders for each mixture from the same batch or blend of batches. Fabricate and cure all beams and cylinders per ASTM C 192/C 192M, using 6" x 6" steel beam forms and 6" x 12" single -use cylinder forms. 205 August 29, 2022 3 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT 2. Cure test beams from each mixture for 3-, 7-, 14-, and 28 -day flexural tests; six beams to be tested per age. 3. Cure test cylinders from each mixture for 3-, 7-, 14-, and 28 -day compressive strength tests; six cylinders to be tested per age. 4. Test beams per ASTM C 78, cylinders per ASTM C 39/C 39M. 5. Using the average strength for each water -cement blend at each age, plot all results from each of the three mixtures on separate graphs for water -cement blend versus: (I) 3 -day flexural strength (ii) 7 -day flexural strength (iii) 14 -day flexural strength (iv) 28 -day flexural strength (v) 3 -day compressive strength (vi) 7 -day compressive strength (vii) 14 -day compressive strength (viii) 28 -day compressive strength 6. From these graphs, select a water -cement blend that shall produce a mixture giving a 28 - day flexural strength equal to or greater than 700 psi for laboratory mix designs and 650 psi for production mix designs. 7. Using the above -selected water -cement blend, select from the graphs the expected 3 -day, 7 -day, 14 -day, and 28 -day flexural strengths and the expected 3-, 7-, 14-, and 28 -day compressive strengths for the mixture. 8. From the above -expected strengths for the selected mixture, determine the following Correlation Ratios: (i) Ratio of the 14 -day compressive strength of the selected mixture to the 28 -day flexural strength of the mixture (for acceptance). (ii) Ratio of the 7 -day compressive strength of the selected mixture to the 28 -day flexural strength of the mixture (for Contractor process control). 9. If there is a change in materials, additional mixture design studies shall be made using the new materials and new Correlation Ratios shall be determined. 10. No concrete pavement shall be placed until the Engineer has approved the Contractor's mixture proportions. The approved water-cementitious materials ratio shall not exceed the maximum value of 0.44 and shall not be increased without the County's written approval. 206 August 29, 2022 4 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT (4) Average CQC Flexural Strength Required for Mixtures To ensure meeting the strength requirements specified above, during production, the mixture proportions selected during mixture proportioning studies and used during construction shall produce a required average CQC flexural strength exceeding the specified strength, R, by the amount indicated below. This required average CQC flexural strength, Ra, shall be used only for CQC operations as specified above and as specified in the previous paragraph. During production, the required Ra shall be adjusted, as appropriate and as approved, based on the standard deviation of equivalent 28 -day strengths being attained during paving. From Previous Test Records: Where a concrete production facility has previous test records current to within 18 months, a standard deviation shall be established per the applicable provisions of ACI 214R. Test records from which a standard deviation is calculated shall represent materials, quality control procedures, and conditions similar to those expected, shall represent concrete produced to meet a specified flexural strength or strengths within 50 psi of the 28 -day flexural strength specified for the proposed work, and shall consist of at least 30 consecutive tests. Perform verification testing, as directed by the Contracting Officer, to document the current strength. A strength test shall be the average of the strengths of two specimens made from the same sample of concrete and tested at 28 days. Required average CQC flexural strength, Ra, used as the basis for selection of concrete proportions shall be the value from the equation that follows, using the standard deviation as determined above: Ra = R + 1.34S Where: S = standard deviation R = specified flexural strength (minimum 650 psi) Ra = required average flexural strength Where a concrete production facility does not have test records meeting the requirements above but does have a record based on 15 to 29 consecutive tests, a standard deviation shall be established as the product of the calculated standard deviation and a modification factor from Table 412-01. TABLE 412-01 MODIFICATION FACTOR FOR CONCRETE PRODUCTION FACILITIES WITH CONSECUTIVE TESTS Number of Tests Modification Factor for Standardl Deviation.; 15 1.16 20 1.08 25 1.03 30 or more 1.00 Without Previous Test Records: When a concrete production facility does not have sufficient field strength test records for calculation of the standard deviation, the required average strength, Ra, shall be determined by adding 15 percent to the specified flexural strength, R. 207 August 29, 2022 5 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT Consolidation Testing: The provisions relating to the frequency and amplitude of internal vibration shall be considered the minimum requirements and are intended to ensure adequate density in the hardened concrete. If a lack of consolidation of the concrete is suspected by the Weld County Project Manager, additional referee testing shall be required. Referee testing of hardened concrete shall be performed by cutting cores from the finished pavement after a minimum of 24 hours for curing. Density determinations shall be made based on the water content of the core as taken. ASTM C642 shall be used for the determination of core density in the saturated -surface dry condition. Failure to meet the above requirements shall be considered evidence that the minimum requirements for vibration are inadequate for the job conditions, and additional vibrating units or other means of increasing the effect of vibration shall be employed so that the density of the hardened concrete as indicated by further referee testing shall conform to the above -listed requirements. All failing concrete shall be removed and replaced. Subsection 412.07(b), paragraph 1 shall be revised to include the following: The slip -form method shall be used for the majority (65% or more) of all mainline concrete paving.

Subsection 412.13(b)(1) shall be revised to include the following: When tie bars are inserted into plastic concrete with a tie bar insertion machine, tie bar location and concrete consolidation shall be subject to the following additional requirements: 1. Each 2,500 linear feet of longitudinal weakened plane joint resulting from the procedure shall have one random location cored where the core intercepts an inserted tie bar. The core shall be six-inch diameter taken in the presence of the Engineer. 2. If non -consolidated concrete is evident above the inserted tie bar, the Contractor shall cease paving operations and submit a corrective action plan in writing for approval. Correction of the joint and further paving shall take place only after written approval of the corrective action plan has been provided by the Engineer. Additional coring may be required, as directed by the Engineer. Coring operations, including patching, shall be at the Contractor's expense. 3. Further failure to consolidate the concrete over the tie -bars shall be justification to preclude the use of the automatic tie -bar insertion for the remainder of the project. Subsection 412.14 references to "curing compound" shall be deleted and replaced with "curing and sealing compound for highway use". Subsection 412.14, paragraph 1 shall be revised to include the following: 208 August 29, 2022 6 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT The "curing and sealing compound" shall be submitted to the Engineer for review and approval at least 14 days prior to its use.

After the mixture has cured for a minimum of 24 hours, the Contractor shall grind each filled core smooth to the same level as the top of adjacent pavement surface. Subsection 412.21(a), paragraph 5 shall be deleted and replaced with the following: The lower tolerance limit (TL) for pavement thickness shall be Plan Thickness (PT). There shall be no incentive/disincentive payment for pavement thickness. Any pavement thicknesses found to be less than Plan Thickness (PT) shall be removed and replaced at the discretion of the Engineer at no cost to the Department. Subsection 412.23, paragraph 1 shall be deleted and replaced with the following: The quantities of concrete pavement to be paid for under these items shall be the number of square yards completed and accepted. The width of measurement shall be the width of the new pavement to the outside edge of the shoulder shown on the typical cross section of the plans, not including any additional width for pavement safety edges.

END OF SECTION 210 August 29, 2022 REVISION OF SECTIONS 420 AND 712 GEOSYNTHETICS 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 shall be revised to include the following: Geotextiles used for erosion control or drainage shall meet the requirements of subsection 712.08 and Table 712- 2a. Geotextile (Drainage) 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 Table 712-b. 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 material 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 . 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 Strength R -Value Overlap Width of Unsewn Seam (Inches) 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. 211 August 29, 2022 2 REVISION OF SECTIONS 420 AND 712 GEOSYNTHETICS 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. 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. Geotextile (Mirafi RS580i) will be measured in place by the square yard of surface area, completed and accepted. Geogrid (Tensar TX -160) will be measured in place by the square yard of surface area, completed and accepted. 212 August 29, 2022 3 REVISION OF SECTIONS 420 AND 712 GEOSYNTHETICS Subsection 420.10 shall be revised to include the following: Payment will be made under: Pay Item Geotextile (Mirafi RS580i) Pay Unit Square Yard Geotextile (Drainage) will not be measured and paid for separately but shall be included in work for the riprap pay item. Overlap and waste for geomembrane, geotextile, and geogrid materials will not be measured and paid for separately but shall be included in the work.

Brief descriptions of test procedures are given in the following notes. 2 Nominal dimensions. 3 Load transfer capability determined per ASTM D6637 and ASTM D7737-11 and expressed as a percentage of ultimate tensile strength. 4 The ratio between the minimum and maximum observed values of radial stiffness at 0.5% strain, measured on rib and midway between rib directions. 5 Radial stiffness is determined from tensile stiffness measured in any in -plane axis from testing per ASTM D6637-10. 6 Resistance to loss of load capacity or structural integrity when subjected to chemically aggressive environments per EPA 9090 immersion testing. 7 Resistance to loss of load capacity of structural integrity when subjected to 500 hours of ultraviolet light and aggressive weathering per ASTM D4355-05. The minimum overlap of the geogrid reinforcement shall be 18 inches. The geogrid reinforcement shall be composed principally of polypropylene or high density polyethylene. 216 August 29, 2022 2 REVISION OF SECTION 420 GEOGRID REINFORCEMENT FOR ROADWAY EMBANKMENT 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 Tri-Ax TX -160 or an approved equivalent meets or exceeds the specifications outlined in Table 420-2. CONSTRUCTION REQUIREMENTS 420.13 Geogrid reinforcement shall be installed per 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 0°F. (b) Site Preparation. Clear, grub and excavate (if necessary) to the design subgrade elevation, stripping topsoil, deleterious debris and unsuitable material from the site. For very soft soils (CBR < 0.5), the Engineer may allow minimal subgrade disturbance and leave root mats in place, cutting stumps and other projecting vegetation as close and even to the ground surface as practical. For moderately competent soils (CBR > 2), the subgrade shall be lightly proof rolled to locate unsuitable materials. Ruts shall be back dragged to provide a smooth surface. (c) Smooth grade and compact the soils using appropriate compaction equipment. Grade or crown the surface for positive drainage away from the construction zone. 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 to the roadway alignment. 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. 217 August 29, 2022 3 REVISION OF SECTION 420 GEOGRID REINFORCEMENT FOR ROADWAY EMBANKMENT 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. 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. (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 per the compaction requirements for embankment for this project or as directed. Care shall be taken to assure the geogrid not damaged. Backfill shall be compacted to 95 percent of the maximum density as determined by AASHTO T-99. The moisture content of the backfill material before and during compaction shall be uniformly distributed throughout each layer and shall be within two percent of optimum. METHOD OF MEASUREMENT 420.14 Geogrid reinforcement will be measured in place by the square yard of surface area, completed and accepted. BASIS OF PAYMENT 420.15 The accepted quantities will be paid for at the contract unit price per square yard. Payment will be made under 218 August 29, 2022 4 REVISION OF SECTION 420 GEOGRID REINFORCEMENT FOR ROADWAY EMBANKMENT Pay Item Geogrid (Reinforcement) Pay Unit Square Yard Payment will be full compensation for all labor, materials, equipment, and other items necessary and incidental to the completion of the work.

BIDDER must acknowledge receipt of this addendum in the space provided in the BID. Failure to acknowledge receipt of an Addendum result in the BID not being reviewed or scored. CONTRACTOR QUESTIONS AND RESPONSES Question 1: Can the bid deadline be moved to later in the day on September 26, 2022? Answer 1: Yes, Weld County has moved the bid deadline to 5 pm on September 26, 2022. Question 2: The bid documents identify July 14, 2023 as the completion date but the Pre -Bid Meeting Agenda shows July 15, 2023 as the completion date. What is the completion date? Answer 2: Since July 15, 2023 falls on a Saturday, which is a non -workday, Friday, July 14, 2023 will be the completion date. Question 3: Page 1, section 1, paragraph 3 of the bid documents shows the mandatory pre -bid meeting to be on November 2, 2022. Isn't the mandatory pre -bid meeting on August 29, 2022? Answer 3: The mandatory pre -bid meeting was held on August 29, 2022. Both of the shortlisted Contractors were in attendance. However, the date for the mandatory pre -bid meeting has been updated on page 1, section 1, paragraph 3. Question 3: If no dirt work activities are occurring onsite, do we still have to have a process control tester onsite? Answer 3: A process control tester is required to be onsite whenever there are activities associated with sections 203, 206, 304, 306, and 603, Section 106 of the specifications outlines the requirements for the process control testing for earthwork. Weld County has included a pay item on the bid tab for the earthwork process control testing. It should also be noted that the Contractor is responsible for providing process control testing for structural concrete, concrete paving, and asphalt paving. Weld County will not pay for the process control testing associated with testing for structural concrete, concrete paving, or asphalt paving. Question 4: When will the proposers be notified in the event interviews are required? Answer 4: The proposers will be notified on Friday, September 30, 2022 if interviews are going to be required. Question 5: Are the bid forms included in the page count for the proposal? Answer 5: No, the required bid forms are not included in the page count for the proposal. These forms are in addition to the 15 page limit set for the proposal. Question 6: Is there an estimate for how much water normally flows in Eaton Draw during the non - irrigation season? Answer 6: It is unknown what the flows in Eaton Draw are during the non -irrigation season. It is estimated that between 10 and 15 cfs flows in Eaton Draw when there is no irrigation water comingled with it. However, it is the responsibility of the Contractor to determine the flows that will have to be diverted through or around the project area in order to meet the requirements of the CDPHE Stormwater Construction Permit. During the irrigation season, the Bliss Ditch adds between 15 and 40 cfs to Eaton Draw. Question 7: Are the full road closure dates that are included in the bid documents allowed to be changed? Answer 7: Yes, the full road closure dates may be changed with the approval of the Board of County Commissioners. The closure dates shown in the bid documents are intended to allow the • Contractor to perform the work that is outside of the existing roadway while still minimizing disruptions to the traveling public. The closure dates were chosen to allow the Contractor enough time to complete the irrigation and drainage work during the winter and still provide enough time to do the required dirt work and paving activities in the spring. Once the full closure of the road starts, the Contractor will be required to have the road opened to traffic by the stated end date. If the road is not opened to traffic, liquidated damages will be assessed as outlined in Section 108. Question 8: Is there an option to use the asphalt millings as embankment material? Answer 8: No. Weld County will retain ownership of the asphalt millings because they will be used by the Operations Division for maintenance activities. The specifications contain information where the asphalt millings are to be hauled and stockpiled. Question 9: The specifications require the Contractor to start construction within 10 days of the Notice to Proceed. Given that 10 days may not be sufficient time to obtain all of the various permits required for the project, will Weld County be flexible on the start date for construction activity? Answer 9: The Contractor is encouraged to start putting together the required permit applications and submittals as soon as the Notice of Award has been issued. Weld County will work with the Contractor, within reason, to establish a date for the start of construction activities. The Contractor should note that the completion date for this project will remain July 15, 2023 regardless of when the Notice to Proceed is issued. Question 10: Can the Onsite Project Manager act as the Erosion Control Inspector? Answer : Per Section 208.03(c) the Superintendent control serve in an erosion control management role. The Onsite Project Manager can serve as the Erosion Control Inspector as long as they are currently certified as a Transportation Erosion Control Supervisor. Proof of current certification shall be provided and kept in the SWMP Notebook.

BIDDER must acknowledge receipt of this addendum in the space provided in the BID. Failure to acknowledge receipt of an Addendum result in the BID not being reviewed or scored. CONTRACTOR QUESTIONS AND RESPONSES Question 1: Are the cast -in -place irrigation structures required to adhere to specifications by the irrigation owner, or are they CDOT? If by the irrigation specification, can the County provide these specifications? Answer 1: Special provisions for the cast -in -place irrigation structures have already been incorporated into the specification or shown on the plans. For the most part, the specifications for the cast -in -place structures are based on the CDOT specifications. Question 2: Per Pavement Final Report page 3, the R -value of the existing soil sample was determined at 17, which is less than the required R -value for embankment. The Project Special Provision per 203.03 on page 110 states that the embankment material shall be a minimum R -value of 20 as specified in the Contract. Can the contractor assume that the existing soil be used as on - site embankment and be exempt from the R -value requirement, with only imported material being required to meet the R -value of 20? Answer 2: If the Contractor wishes to utilize onsite soils as embankment material, they will have to show that the soil has an R -value of at least 20. Question 3: The Project Special Provision per 412.04.(a) states that the cement shall be Type I -II. Currently the cement market is in the process of transitioning the available cement from the Type I- II to 1L. Since the target date for full transition is still fluid, the available cement type can change by the time the work is required. Please consider revising the required cement to be Type I -II to Type I -II or 1L. Answer 3: Weld County will change the specification to allow either Type I -II or Type 1L cement. Question 4: Sheet Number 100 through 102 Note 5 states that any panel that is smaller than 12'x15' shall be reinforced with a wire mesh. While the jointing plans can be subject to change per Contractor's recommendations, the current plan provided by the County will require almost all the pavement to be reinforced. Please clarify if this is the County's intent or to only reinforce the pavement that are odd -shaped panels. Answer 4: The intent of the wire reinforcement is to help provide additional strength to odd -shaped panels. The jointing legend shown on sheets 100 through 102 identifies the panels that are to be reinforced with an "R". Sheets 100 and 102 do not appear to show any panels that are to be reinforced with wire mesh. The only place the "R" appears are in the odd -shaped panels shown on sheet 101. There may be additional panels that will require wire reinforcing depending on how the Contractor plans to do the jointing. Question 5: Please clarify if the Proposed Construction Schedule is included in the 15 page count for the proposal document. Answer 5: Yes, the proposed construction schedule will be included in the 15 page count. It is acceptable for the Construction Schedule to be on an 11x17 sheet. Each 11x17 sheet that contains the proposed construction schedule will be counted as 1 page. For example, if the proposed construction schedule takes 3 11x17 sheets, it will count as 3 pages. Prepared By: Clay Kimmi, P.E., Senior Engineer September 13, 2022 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT Sections 412 and 705 of the Standard Specifications are hereby revised for this project as follows: Subsection 412.01 shall include the following inserted prior to the first sentence. 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. Subsection 412.03 shall be deleted and replaced with the following: Class P concrete shall conform to the requirements for an optimized mix design and shall be per Sections 106.06(a) and 601.02. The strength of the concrete shall be considered acceptable when the average equivalent 28 -day flexural strengths for each lot are above the "Specified Flexural Strength," of 650 psi for both the plan value and the lower tolerance limit (Table 105-11). In addition, no individual set (two specimens per sublot) in the lot is 25 psi or more below the equivalent "Specified Flexural Strength." If any lot or sublot, respectively, fails to meet the above criteria, the lot or sublot shall be removed and replaced at no additional cost. ACI 318 cannot be used to dispute acceptance strength results. Evaluation of low strength test results shall follow CP65 Method B. Subsection 412.04 shall be deleted and replaced with the following: 412.04 Proportioning. Proportioning shall conform to the requirements below. (a) The maximum allowable amount of Fly Ash shall be 20%. Class F fly ash shall be used. Cement shall be Type I -II or Type IL. (b) Proportioning shall conform to the requirements of subsection 601.05 in addition to the requirements below: (1) Mixture Proportions (i) Composition. Concrete shall be composed of cementitious material, water, fine and coarse aggregates, and admixtures. Supplementary Cementitious Materials (SCM) choice and usage shall be per Section 601 of the Specifications. The total cementitious material content shall be at least 520 LB/CY. Admixtures shall consist of air -entraining admixture and also may include as approved, water -reducing admixture. (ii) Proportioning Studies. Trial design batches, mixture proportioning studies, and testing requirements are the responsibility of the Contractor. Trial mixtures having proportions, slumps, and air content suitable for the work shall be based on methodology described in ACI 211.1, modified as necessary to accommodate flexural strength. Submit test results, including: 1. Coarse and fine aggregate gradations and plots; September 13, 2022 2 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT 2. Combined aggregate gradation and coarseness/workability plots; 3. Coarse aggregate quality test results, including deleterious materials; 4. Fine aggregate quality test results; 5.

Recommended proportions/volumes for proposed mixture and each of three trial water-cementitious materials ratios; 10. Individual beam and cylinder breaks; 11. Flexural and compressive strength summaries and plots; 12. Correlation ratios for acceptance testing and CQC testing; and 13. Historical record of test results documenting production standard deviation (if available) (iii) Water -Cement Ratio. At least three different water -cement ratios, which shall produce a range of strengths encompassing that required on the project, shall be used. The maximum allowable water -cement ratio shall be per Table 601-1 of the Specifications. Laboratory trial mixtures shall be proportioned for maximum permitted slump and air content. (2) Trial Mixture Studies. Separate sets of trial mixture studies shall be made for each combination of cementitious materials and each combination of admixtures proposed for use. No combination of either shall be used until proven by such studies, except that, if approved in writing and otherwise permitted by these specifications, an accelerator or a retarder may be used without a separate trial mixture study. If the Contractor is manufacturing these mixes and they are not on the CDOT approved mix design list (APL), separate trial mixture studies shall be made for concrete for each placing method (slip form, fixed form, or hand placement) proposed. The temperature of concrete in each trial batch shall be reported. Each mixture shall be designed to promote easy and suitable concrete placement, consolidation and finishing, and to prevent segregation and excessive bleeding. (3) Mixture Proportioning for Flexural Strength. The following step-by-step procedure shall be followed: 1. Fabricate all beams and cylinders for each mixture from the same batch or blend of batches. Fabricate and cure all beams and cylinders per ASTM C 192/C 192M, using 6" x 6" steel beam forms and 6" x 12" single -use cylinder forms. September 13, 2022 3 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT 2. Cure test beams from each mixture for 3-, 7-, 14-, and 28 -day flexural tests; six beams to be tested per age. 3. Cure test cylinders from each mixture for 3-, 7-, 14-, and 28 -day compressive strength tests; six cylinders to be tested per age. 4. Test beams per ASTM C 78, cylinders per ASTM C 39/C 39M. 5. Using the average strength for each water -cement blend at each age, plot all results from each of the three mixtures on separate graphs for water -cement blend versus: (i) 3 -day flexural strength (ii) 7 -day flexural strength (iii) 14 -day flexural strength (iv) 28 -day flexural strength (v) 3 -day compressive strength (vi) 7 -day compressive strength (vii) 14 -day compressive strength (viii) 28 -day compressive strength 6. From these graphs, select a water -cement blend that shall produce a mixture giving a 28 -day flexural strength equal to or greater than 700 psi for laboratory mix designs and 650 psi for production mix designs. 7. Using the above -selected water -cement blend, select from the graphs the expected 3 - day, 7 -day, 14 -day, and 28 -day flexural strengths and the expected 3-, 7-, 14-, and 28 - day compressive strengths for the mixture. 8. From the above -expected strengths for the selected mixture, determine the following Correlation Ratios: (i) Ratio of the 14 -day compressive strength of the selected mixture to the 28 -day flexural strength of the mixture (for acceptance). (ii) Ratio of the 7 -day compressive strength of the selected mixture to the 28 -day flexural strength of the mixture (for Contractor process control). 9. If there is a change in materials, additional mixture design studies shall be made using the new materials and new Correlation Ratios shall be determined. September 13, 2022 4 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT 10. No concrete pavement shall be placed until the Engineer has approved the Contractor's mixture proportions. The approved water-cementitious materials ratio shall not exceed the maximum value of 0.44 and shall not be increased without the County's written approval. (4) Average CQC Flexural Strength Required for Mixtures To ensure meeting the strength requirements specified above, during production, the mixture proportions selected during mixture proportioning studies and used during construction shall produce a required average CQC flexural strength exceeding the specified strength, R, by the amount indicated below. This required average CQC flexural strength, Ra, shall be used only for CQC operations as specified above and as specified in the previous paragraph. During production, the required Ra shall be adjusted, as appropriate and as approved, based on the standard deviation of equivalent 28 -day strengths being attained during paving. From Previous Test Records: Where a concrete production facility has previous test records current to within 18 months, a standard deviation shall be established per the applicable provisions of ACI 214R. Test records from which a standard deviation is calculated shall represent materials, quality control procedures, and conditions similar to those expected, shall represent concrete produced to meet a specified flexural strength or strengths within 50 psi of the 28 -day flexural strength specified for the proposed work, and shall consist of at least 30 consecutive tests. Perform verification testing, as directed by the Contracting Officer, to document the current strength. A strength test shall be the average of the strengths of two specimens made from the same sample of concrete and tested at 28 days. Required average CQC flexural strength, Ra, used as the basis for selection of concrete proportions shall be the value from the equation that follows, using the standard deviation as determined above: Ra = R + 1.34S Where: S = standard deviation R = specified flexural strength (minimum 650 psi) Ra = required average flexural strength Where a concrete production facility does not have test records meeting the requirements above but does have a record based on 15 to 29 consecutive tests, a standard deviation shall be established as the product of the calculated standard deviation and a modification factor from Table 412-01. September 13, 2022 5 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT TABLE 412-01 MODIFICATION FACTOR FOR CONCRETE PRODUCTION FACILITIES WITH CONSECUTIVE TESTS Number of Tests 15 Modification Factor for Standard Deviation 1.16 20 1.08 25 1.03 30 or more 1.00 Without Previous Test Records: When a concrete production facility does not have sufficient field strength test records for calculation of the standard deviation, the required average strength, Ra, shall be determined by adding 15 percent to the specified flexural strength, R. Consolidation Testing: The provisions relating to the frequency and amplitude of internal vibration shall be considered the minimum requirements and are intended to ensure adequate density in the hardened concrete. If a lack of consolidation of the concrete is suspected by the Weld County Project Manager, additional referee testing shall be required. Referee testing of hardened concrete shall be performed by cutting cores from the finished pavement after a minimum of 24 hours for curing. Density determinations shall be made based on the water content of the core as taken. ASTM C642 shall be used for the determination of core density in the saturated -surface dry condition. Failure to meet the above requirements shall be considered evidence that the minimum requirements for vibration are inadequate for the job conditions, and additional vibrating units or other means of increasing the effect of vibration shall be employed so that the density of the hardened concrete as indicated by further referee testing shall conform to the above - listed requirements. All failing concrete shall be removed and replaced. Subsection 412.07(b), paragraph 1 shall be revised to include the following: The slip -form method shall be used for the majority (65% or more) of all mainline concrete paving. The Contractor's slip -form concrete paving machine shall be capable of paving a minimum width of 16 feet. The Contractor shall submit to the County the specific equipment capabilities for review, prior to any concrete paving being placed. Subsection 412.10 shall be revised to include the following: A material transfer device shall be used when placing manual poured sections of PCCP. Concrete placed in areas that result in panels less than 12 feet by 15 feet or panels that are oddly shaped (i.e., not rectangular) shall be reinforced with welded wire mesh that conforms to Section 709.04 of the Weld County Special Revisions. Subsection 412.13(b)(1) shall be revised to include the following: When tie bars are inserted into plastic concrete with a tie bar insertion machine, tie bar location and concrete consolidation shall be subject to the following additional requirements: 1. Each 2,500 linear feet of longitudinal weakened plane joint resulting from the procedure shall have one random location cored where the core intercep(s an inserted tie bar. The core shall be six-inch diameter taken in the presence of the Engineer. September 13, 2022 6 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT 2. If non -consolidated concrete is evident above the inserted tie bar, the Contractor shall cease paving operations and submit a corrective action plan in writing for approval. Correction of the joint and further paving shall take place only after written approval of the corrective action plan has been provided by the Engineer. Additional coring may be required, as directed by the Engineer. Coring operations, including patching, shall be at the Contractor's expense. 3. Further failure to consolidate the concrete over the tie -bars shall be justification to preclude the use of the automatic tie -bar insertion for the remainder of the project. Subsection 412.14 references to "curing compound" shall be deleted and replaced with "curing and sealing compound for highway use". Subsection 412.14, paragraph 1 shall be revised to include the following: The "curing and sealing compound" shall be submitted to the Engineer for review and approval at least 14 days prior to its use. Subsection 412.16, paragraph 2 shall be revised to include the following: All concrete cores shall be the full depth of the concrete thickness. All concrete cores shall be repaired using a non -shrink grout such as HD -50 or approved equivalent. The non -shrink grout shall be mixed with 3/8 inch pea gravel when the dimension in any direction exceeds 2 inches. The non -shrink grout mixture shall be placed in the empty core hole. The mixture shall be vibrated to assist with consolidation of the material. The mixture shall be domed above the top of the adjacent pavement surface a minimum of 1/8 inch. After the mixture has cured for a minimum of 24 hours, the Contractor shall grind each filled core smooth to the same level as the top of adjacent pavement surface. Subsection 412.21(a), paragraph 5 shall be deleted and replaced with the following: The lower tolerance limit (TL) for pavement thickness shall be Plan Thickness (PT). There shall be no incentive/disincentive payment for pavement thickness. Any pavement thicknesses found to be less than Plan Thickness (PT) shall be removed and replaced at the discretion of the Engineer at no cost to the Department. Subsection 412.23, paragraph 1 shall be deleted and replaced with the following: The quantities of concrete pavement to be paid for under these items shall be the number of square yards completed and accepted. The width of measurement shall be the width of the new pavement to the outside edge of the shoulder shown on the typical cross section of the plans, not including any additional width for pavement safety edges. The width for measurement includes additional widening where called for, or as otherwise directed by the Engineer in writing. The length shall be measured horizontally along the centerline of each roadway or ramp. Subsection 412.24 shall be revised to include the following: Construction of Pavement safety edges shall not be measured and paid separately but shall be included in the work for Concrete Pavement. A one-year warranty period shall apply to all Portland Cement Concrete Pavement (PCCP) incorporated into the project. The warranty period shall begin on the date Final Acceptance is issued by the County. September 13, 2022 7 REVISION OF SECTION 412 PORTLAND CEMENT CONCRETE PAVEMENT (a) Any PCCP which does not meet the contract specifications, prior to or throughout the warranty period, or has visible deficiencies or failures, shall be removed and replaced at the Contractor's expense. (b) The PCCP shall be inspected by County staff on a 6 -month basis during the warranty period. If deficiencies become apparent during the warranty period, the County shall prepare a warranty letter with a detailed description of the PCCP which has to be removed and replaced. The County and Contractor shall then meet to finalize the list of deficiencies to be addressed, the construction methods to be utilized, and the timing of the warranty work to be completed. In such case that the Contractor refuses to participate in this procedure, after a non -responsive period of 30 day, the County shall arrange with a qualified contractor of their choosing to compete the warranty work. The Contractor shall be liable for all costs. (c) The PCCP deficiencies include but is not limited to the following: 1. Pavement panels containing one or more cracks through the full depth of the panel resulting in separating the panel into two or more parts. 2. Pavement panels containing excessive honeycombed areas that result in spalling of the PCCP or pooling of drainage water. 3. Pavement panels which contain any voids greater in depth than one-half of the PCCP total thickness. 4. Pavement panels which do not meet the minimum smoothness testing requirements. 5. Joints which are spalled over 50% of their length. 6. Pavement panels which do not meet the specified grades in the plans or have any areas which drainage water pools on the surface to a depth of greater than 0.5 inches. (d) Any PCCP removed shall be replaced with new PCCP meeting the original project specifications, depth, color, and finish. Any replacement panel shall be tested and verified to obtain adequate strength prior to allowing traffic on it. In the case of PCCP panel replacement associated with the one- year warranty period, a new one-year warranty period shall commence on the date which the replacement panel construction is accepted by the County. Subsection 412.24, paragraph 8 shall be deleted and replaced with the following: Incentive and Disincentive Payments (I/DP) will not be made for this project.

BIDDER must acknowledge receipt of this addendum in the space provided in the BID. Failure to acknowledge receipt of an Addendum result in the BID not being reviewed or scored. CONTRACTOR QUESTIONS AND RESPONSES Question 1: What are the expectations for internet service on this project? Answer 1: The attached revision to section 620 of the Specifications has details on the internet service requirements for this project. In order of preference the internet service shall be: (1) Hard wired broadband or DSL (i.e., Xfinity, Comcast, etc.) (2) Radio broadband (i.e., Rise Broadband, etc.) (3) Satellite broadband (i.e., HughesNet, etc.) (4) Cellular radio — if speed and signal strength requirements are met. (5) Wireless hotspots — only if there is no other option, if the speed and data caps are met, and upon written approval of the Engineer. One hotspot shall be provided per County employee assigned to the project. Wireless hotspot configurations must include WPA2 and AES encryption for SSID authentication. It is known that there is radio broadband internet service in the area so wireless hotspots are not an acceptable form of internet connection for this project. Question 2: What in kind of printer will be required for this project? Answer 2: The revision to Section 620 of the Specifications outlines the printer/copier requirements for this project. A desktop printer/copier will not be sufficient for this project. The printer/copier shall be capable of connecting to the internet router and shall be capable of sending files to multiple email addresses. Question 3: Is it acceptable to utilize on -site soils with R -values less than 20 in non-structural areas, i.e., outside of the roadway prism or driveway prism? Answer 3: Upon further review and consideration, Weld County will allow the use of on -site R-17 or greater soils within the project area. Areas containing soils that are less than R-17 will not be allowed to be used for embankment purposes in the project area. Based on the Pavement Design Report, it appears that bore holes BH-2 and BH-6 will likely have soils that do not meet the R-17 criteria. The Contractor shall be responsible for proving that onsite soils meet the R-17 criteria before it can be incorporated into the project. The revised sheets showing the allowable use of on -site R-17 materials have been attached to this addendum. Question 4: Sheet 135 calls for a new air valve to be installed on the 18" cast iron pipe, but there are no details or specifications for the air valve. Can details or specifications be provided? Answer 4: A detail for the vent pipe is shown below and has been added to sheet 135 of the plans. The revised sheet 135 is included in this addendum. 6.5' MIN (VENT PIPE) V5/:07:K/ PROVIDE 6` MECHANICAL JOINT RESTRAINT FROM TEE TO STEEL PIPE 18"x 18'x 6- M ECHAN ICAL JOINT TEE POL YETH YLEN E BOND BREAKER 18" CAST IRON PIPE --.ess PROVIDE 18' MECHANICAL JOINT RESTRAINT FROM TEE TO CAST IRON PIPE PROVIDE 4 4 SF OF BEARING AREA, 0.4 CU YDS (MIN) 6" STEEL VENT PIPE #5 ANCHOR BAR BENT OVER TEE t2 REQUIRED) IRRIGATION VENT STAND PIPE DETAIL t 8' CAST IRON PIPE ANCHOR BAR Pa YETHYLENE BOND BREAKER IRRIGATION VENT PIPE DETAIL NOT TZ? SCAlE I/c PROVIDE BIRD PROOF VENT CAP 6' STEEL VENT PIPE et, SECTION A -A Question 5: Can an Excel version of the bid schedule be provided with the understanding the calculations are the responsibility of the Contractor? Answer 5: No. However, it is possible for the Contractor to export the bid tabulation found in the PDF to Excel. Question 6: What percentage of the Contract does the prime need to self -perform? Answer 6: Per the Weld County Revision to Section 108.01, paragraph 2, the Contractor shall self -perform 30% or more of the total original contract amount. Question 7: Can the bid date/time be postponed by 2 days? Answer 7: No. Question 8: Paragraph 7 on Page 57 of the bid documents can be interpreted that work inside the roadway prism do not need to be completed by March 31, 2023. It is assumed this is not the case as that all work associated with allowing flows to occur need to be done by March 31, 2023, please confirm. Answer 8: The irrigation and drainage facilities are comingled throughout the site. All work associated with the irrigation and drainage facilities has to be completed by March 31, 2023. Portions of the roadway prism containing an irrigation or drainage facility have to be completed prior to March 31, 2023. It should also be noted, the Weld County Revision to Section 203.07(a) requires the embankment to be constructed to a minimum of 1 foot above the top pipe elevation and for a minimum of at least 5 times the pipe diameter or span of the pipe prior to a pipe being installed. Therefore, areas of the embankment that will have an irrigation or drainage facility installed through it shall also be completed by March 31, 2023. Question 9: The Weld County Revision to Section 104.02(a), specifically the list of items not considered differing site conditions, i.e., items 2, 5,6, 7, 8, 9, 10, and 11, place a lot of risk on the Contractor and therefore unnecessary costs to the Owner. Can these items be revisited? Answer 9: No. Question 10: Similarly, to the above question, based on the response to Q&A 2 in addendum 3, should the bidding contractors assume that none of the existing material can be reused in order to allow for fair bidding? Answer 10: See the response to question 3 in this addendum. Question 11: What item should the costs of handling and disposal materials not meeting an R -value of 17 be accounted for? Answer 11: Since on -site soils which meet an R -value of 17 can now be used as embankment material, this question no longer applies. Question 12: Per the Weld County Revision to Section 202, Removal Asphalt Mat (Planing), millings are to become the property of the County and delivered to the address(es) provided. Is this the case for full depth removal? Answer 12: All asphalt is to be removed to the full asphalt depth using a milling machine. Question 13: Will the County have equipment on site to handle and stockpile the material or is the Contractor expected to do this? Answer 13: The Contractor shall handle and stockpile all millings at the delivery sites. The costs of handling the material and stockpiling shall be included in the cost of the work. Question 14: The Weld County Revision to Section 206.02(a) states that any flowfill that has a 28 days strength greater than 1,500 psi is to be removed and replaced by the Contractor, however that same section dictates the design of the mix. If the placed material meets the mix design requirements of the County's specification but is above the maximum strength is that considered the Contractor's error? Answer 14: In the past, contractors and their concrete suppliers have added extra cement to the flowfill mix resulting in flowfill that was in excess of 3,000 psi at 28 days. The purpose of the revision is to ensure that the Contractor and their concrete supplier are providing flowfill that will meet between 1,000 and 1,500 psi at 28 days. If the Contractor feels that the flowfill mix design provided in the specifications will result in strengths that exceed 1,500 psi at 28 days, the Contractor may provide another mix design for the flowfill. Question 15: Revision of Section 207 states that amendments for Topsoii(On-Site) will not be paid for but should be included in the work. Does the County have test results of the existing topsoil to determine if it meets the requirements? Answer 15: No, the County does not have any test results for the on -site topsoil. Question 16: If the existing topsoil does not meet the requirements of the Contract, will the County consider payment to reduce potential costs to the County? Answer 16: The Revision to Section 207 is based on CDOT's revision which becomes effective on October 1, 2022. The CDOT revision states that the amendments for on -site topsoil are to be included in the work. It should also be noted that the County is paying to supplement the topsoil with the hydraulic growth amendment known as "Biotic Earth Black". If the topsoil has to be supplemented with additional fertilizer or soil conditioners that are in addition to the Biotic Earth Black, the Contractor shall bear those additional costs. Question 17: The existing area versus the final area of topsoil (i.e., stockpile topsoil vs redistribute topsoil (6 inches)) do not appear to match. How will import or export be paid? Answer 17: The bid tab shows that 11,390 CY of topsoil is to be stockpiled and 11,390 CY of topsoil is to be redistributed. Per the Weld County Revision to Section 106.06, excess soil materials generated from the project shall not be disposed of within the project area without written authorization by the Engineer. Per the Weld County Revision to Section 207.01, excess topsoil shall become the property of the Contractor and shall be removed from the project at no additional cost. If the 11,390 CY of stockpiled topsoil is not sufficient to cover the site, Weld County work with the Contractor to pay for imported topsoil that meets the project requirements. Question 18: What is dictating the 150 day closure of the intersection? Answer 18: The 150 day closure is the length of time that Weld County feels will give the Contractor sufficient time to construct the project in accordance with the phasing plan that was provided in the bid documents while minimizing the impacts to the traveling public. The Contractor is free to propose a different phasing plan and length of closure provided it significantly expedites the completion of the project. However, Weld County is not required to approve a different closure duration. Question 19: Will the duration of diverting/channeling water flows without the need of pumping/treating be paid for by the day? If not, how will this be paid? Answer 19: In some cases, the SWMP plan shows offsite water being diverted and flowing along the outside edge of the temporary berms. In these, the diversion is being included in the lineal footage unit price for Temporary Berms. In other instances, the Contractor may have to provide a method for diverting or channelizing the off -site flows through or around the project. It may be necessary for the Contractor to submit a plan for the temporary diversion and/or channelization of the offsite waters for review and acceptance by the Engineer. The payment for the temporary diversion of water through and/or around the project site will be paid for by the linear foot from the Erosion Control Force Account. Prior to authorization to use the Erosion Control Force Account, the Contractor shall provide unit costs for the type of diversion to be utilized. Material submittals shall be submitted to the Engineer for review and acceptance by the Engineer. Question 20: What is the need for maturity meters if concrete compressive strength is determined by cylinder breaks (reference revision of section 601)? Answer 20: This question appears to be in reference to the Weld County Revision to Section 601.05. This specific section is related to the mix design submittal requirements for all concrete including the Class P concrete. Maturity meters are required to be placed in the concrete paving per Section 412 of the Specifications so the Class P concrete mix design shall include a maturity correlation curve. The only concrete is being accepted based on compressive strength cylinder breaks is the Class D concrete. Maturity meters are not required for Class D concrete. Question 21: Does the County have a location in mind for the field offices? Answer 21: Weld County has not identified a specific location for the field offices. Per the Weld County Revision to Section 620.06 of the Specifications, the field office shall be located within 'A mile of the project site. Question 22: Has the County coordinated with the electrical utilities to provide a drop for power to provide electricity to the field offices? Answer 22: Coordination with the electrical utility for a power drop is the responsibility of the Contractor. The use of generators to provide 24/7 power is acceptable provided the generator meets the requirements outlined in the Weld County Revision to Section 620. Question 23: Is a field lab required to be provided? Answer 23: A field laboratory is not required to be provided. Question 24: The bid documents state the Contractor is required to keep all existing and new drainage structures and features functional and maintain adequate drainage throughout the construction area at all times during construction. There are several locations/items this impacts, can the County provide some clarity on what drainage structures and features this applies to and what the flows are? Answer 24: The intent of this requirement is to ensure that properties upstream and downstream of the project are not impacted due to runoff from storm events. It is also intended to prevent flooding of project site. In short, any existing ditch or culvert has to remain operational until the new drainage infrastructure has been installed and is fully functional. The drainage report that was provided on the Sharefile site has information on the flows. Question 25: Note under Irrigation Notes on Sheet 4 conflicts with the special provisions, please clarify. Answer 25: Irrigation Note 5 on sheet 4 of the construction plans has been updated to be between November 1 and March 31 which is consistent with the special provisions. Question 26: Are any special access needs for planting season known that may not be reflected on the plans that the Contractor needs to be aware of? Answer 26: It is to the Contractor's responsibility to ensure that the landowners and farmers have access to the surrounding properties at all times. This means the Contractor has to coordinate with the landowners and farmers to determine when and how the access to the property will be provided. Question 27: There appears to be proposed improvements outside of the PR -ROW. How will this be handled'? Answer 27: There are several areas where improvements will be made outside of the proposed ROW. Temporary construction easements (TCE) and permanent easements (PE) have been obtained for the areas where work is occurring outside of the proposed ROW. The TCEs and other easements have been acquired are shown on the construction plans and ROW plans. There maybe isolated instances where the Contractor will have to coordinate with the landowners to ensure the transition of an access works for the landowner's needs. In those isolated instances, the Contractor shall provide a copy of the landowner's authorization to the Engineer. Question 28: Has all the ROW required for this project been acquired? If not, when is this expected? Answer 28: All ROW has either been obtained or has a possession and use agreement in place for the project. Question 29: The trash conveyor is shown to be reset by the owner, does this include the electrical? Furthermore, has this duration been accounted for the in March 31 deadline'? Answer 29: The trash conveyor is to be reset by the landowner will be reset at the owner's convenience after the irrigation work has been completed. The landowner will be responsible for ensuring the electrical power is provided. The Contractor shall coordinate with the landowner during the removal and resetting of the conveyor. Question 30: Sheet 142 calls for fillets on the bottom of the walls below the construction joint. Is this an 8" fillet? Answer 30: Yes, 8" x 8" fillets, Typical, is shown for the label in the upper left corner Sheet 142, CBC Section A -A. Question 31: Can the construction joint be moved to the top of the bottom slab? Answer 31: Yes, a note has been added to Sheet 142. If the Contractor wishes to exercise the option to move the construction joint, an RFI shall be requested prior to the start of the CBC box construction. A revised sheet 142 has been included in this addendum. Question 32: Sheet 142 shows a radiused corner, can this be fillet rather than radiused? Answer 32: Yes, a note has been added to sheet 142. If the Contractor wishes to change the radius to a fillet, an RFI shall be requested prior to the start of the CBC box construction. A revised sheet 142 is included in this addendum. Question 33: Will the County allow 20% RAP in the HMA (SX)(100)(PG64-28)? Answer 33: Yes, Weld County will RAP in the HMA (SX)(100)(PG64-28). The Contractor's mix design for the HMA (SX)(100)(PG64-28) shall clearly indicate the percentage of RAP that will be in the mix. An updated Weld County Revision to Section 401 of the Specifications is included in this addendum.

AF Sheet Subset S2 OF 5 i i GR 45 Sheet Number 140 October 13, 2022 Bid Request No B2200115, CR 66 and CR 41 Intersection Project Weld County, Colorado ADDENDUM NUMBER SIX The following shall be incorporated into the CONTRACT DOCUMENTS, for the above -referenced PROJECT • Questions and Answers ▪ Revised Bid Schedule (changes shown in red) o Please note that a Class 2 Field Laboratory has been added to the Bid Schedule ▪ Addition of Sheet 120A to Plans (Pipe Bedding Details) • Revision to Sheet 140 All other terms and conditions of the CONTRACT DOCUMENTS shall remain unchanged BIDDER must acknowledge receipt of this addendum in the space provided in the BID Failure to acknowledge receipt of an Addendum result in the BID not being reviewed or scored QUESTIONS AND ANSWERS Question 1 The Special Provision revision to 603 09 states that flowfill shall be used to backfill all drainage culverts to a minimum of one foot above the top of the pipe Can a detail be provided, as clarification is needed if flowfill should be used as the bedding and backfill, or if we bed with aggregate and then use flowfill as the'backfill to one foot above the pipe Answer 1 A detail for the extents of flowfill around the pipes is provided in this addendum The detail should be inserted into the plan set as Sheet 120A Question 2 Similar to the above question, is this required for the full length of all pipe or just that within the roadway prism? Answer 2 The definition of the roadway prism has been revised in the project special provisions to extent from toe of slope to toe of slope A detail for the extents of flowfill along the length of the pipe is provided in this addendum The detail should be inserted into the plan set as Sheet 120A Question 3 Similar to the above question, there is a bid item for structure backfill (flowfill) in the bid documents, are we to assume that the flowfill for the drainage culverts will be paid per this pay item or that the flowfill be included with the drainage culverts pay items? Answer 3 The flowfill item in the bid tabulation is only for the flowfill that is to be placed around the cast in place box culvert Per the Weld County Special Revision to Section 603 13 of the Specifications, "Structure excavation, structure backfill including flowfill, filter material, and bedding material required for all pipes, culverts and pipe culvert extensions, inlets, storm sewer pipes, manholes, and other drainage structures will not be measured and paid for separately but shall be included in the work " Question 4 Is the Weld County flowfill required or can a CDOT approved flowfill be used? Answer 4 Only the use of Weld County flowfill or an approved flow fill mix design will be allowed to be used Weld County does not allow the use of CDOT flowfill because they do not provide the strength that Weld County needs Question 5 It is our understanding that future widening of the roads being construction has dictated the jointing plans Please provide clarification or further 'detail on this Answer 5 The jointing plan shown in the Construction Plans was created by our consultant knowing that it is extremely likely that CR 66 from Highway 85 to CR 47 will be upgraded in the near future In order to avoid having joints in the future wheel paths, our design consultant was directed to provide a jointing plan that would accommodate the future plans Weld County is trying to minimize the amount of concrete paving that would have to be removed in the future Question 6 The revised detail for the flowfill backfill of the culvert is for the section of the CBC, are we to assume this detail and dimensions are the same for the wingwalls? Answer 6 No Question 7 Is there a maximum pour lift height for the flowfill backfill? Answer 7 As stated in Section 206 03, paragraph 15 of the Specifications limits the maximum pour lift to 3 feet unless otherwise approved by the Engineer Question 8 With Addendum 5 modifying dates of the proposal, how quickly will the intended contract be notified of the intent to award to either them or the other bidding contractor as this may impact the bidding contractor's decision to bid on other work'? Answer 8 Weld County anticipates making a recommendation to the Board of County Commissioners on October 31, 2023 Pending the BOCC's decision, it is anticipated that the selected contractorwould be issued a Notice of Award on or about October 31, 2023 , Question 9 With the NTP being delayed, please confirm that the March 31 deadline for ditch flows still needs to be maintained If this is not the case for all ditch flows, please identify which ditches do not need to be completed by March 31 and when they need to be completed by Answer 9 The deadline for having the drainage structures that handlehrngation flows remains unchanged It will remain as March 31, 2023 Question 10 The change in the structural backfill bid item from 97 CY to 1284 CY is adding significant cost to the project In an effort to provide the best value to the County, can the detail be revised to better reflect the OSHA excavation criteria and the means and\methods that will be used to construct the concrete box culvert'? Answer 10 A revision to sheet 140 has been included to reflect the OSHA excavation criteria Question 1 Can the June 15th deadline for seeding be extended by two weeks'? Answer 10 No, the June 15. deadline for seeding cannot be extended The June 15. date is based on historical moisture and temperatures for the area It is 'Weld County's experience that seeding 'performed after June 15. does not germinate very well unless it is irrigated The Contractor's attention should also be directed to The Weld County Revision to Sections 207, 208, and 212 of the Specifications that pertain to seeding requirements Section 212 01 states "Multiple seeding operations shall be anticipated as portions of the job site shall be seeded as they are completed in orderlto take advantage of the growing conditions and to comply with Section 208 and the remainder of this section " Question 10 Can the maximum duration of the full intersection closure be increased'? Answer 10 No, the duration of the full intersection closure will remain at 150 days Prepared By Clay Kimmi, P E , Senior Engineer BID TABULATION (Revised 10/13/22) Bid # ITEM # ITEM DESCRIPTION UNIT QUANTITY UNIT PRICE TOTAL COST 1 201-00000 CLEARING AND GRUBBING LS 1 2 202-00000 REMOVAL OF STRUCTURES AND OBSTRUCTIONS LS 1 3 202-00001 REMOVAL OF STRUCTURE EA 4 4 202-00010 REMOVAL OF TREE EA 2 5 202-00025 REMOVAL OF DITCH LINING LF 791 6 202-00035 REMOVAL OF PIPE LF 1,786 7 202-00155 REMOVAL OF WALL LF 193 8 202-00246 REMOVAL OF ASPHALT MAT (PLANING) (SPECIAL) SY 16,792 9 202-00250 REMOVAL OF PAVEMENT MARKING SF 375 10 202-00810 REMOVAL OF GROUND SIGN EA 9 11 202-01000 REMOVAL OF FENCE LF 373 12 203-00050 UNSUITABLE MATERIAL CY 7,430 13 203-00060 EMBANKMENT MATERIAL (COMPLETE IN PLACE) CY 45,873 14 203-01100 PROOF ROLLING HOUR 80 15 203-01500 BLADING HOUR 40 16 203-01550 DOZING HOUR 40 17 203-01597 POTHOLING HOUR 80 18 203-02330 LABORER HOUR 100 19 203-00500 ROCK FILL (57-67) (CONTINGENCY) CY 1,000 20 203-00510 ROCK FILL (3" MINUS) (CONTINGENCY) CY 1,000 21 206-00000 STRUCTURE EXCAVATION CY 2,489 22 206-00050 STRUCTURE BACKFILL (SPECIAL) CY 617 23 206-00060 STRUCTURE COUNTY MIX) BACKFILL (SPECIAL) (FLOW -FILL) (WELD CY 380 24 206-00100 STRUCTURE BACKFILL (CLASS 1) CY 227 25 207-00205 REDISTRIBUTE TOPSOIL (6 INCHES) CY 11,390 26 207-00210 STOCKPILE TOPSOIL CY 11,390 27 208-00002 EROSION LOG TYPE 1 (12 INCH) LF 5,251 iBid #- ,: .

The grades coming into and out of the intersection combined with obstructions along the north side of CR 66 have created a hazardous situation for the traveling public. This project will correct these issues and increase the safety of the roadway for its users. Throughout IHC Scott's history working with Weld County we have tackled many projects such as these and have delivered high quality, cost effective and on time products. We value the relationship we have built with the County on similar projects and look forward to continuing to build on our relationship with this project. The following proposal details our: • Understanding of the scope of the project. • Methods we will employ to complete the project. • Critical issues we have identified and our approach to mitigate them. • Project approach to control cost, quality, subcontractors and schedule. • Familiarity with the work location and Weld County • Cost and Schedule for the project. IHC Scott is pleased to present this proposal to Weld County and we look forward to another successful project in partnership with Weld County. SCHEDULE IHC Scott has a long standing history of completing projects on time or ahead of schedule. We fully vet the plans and specifications to identify the most effective path to progress the work. Our process identifies the items that need to be procured early, potential hurdles and also potential opportunities. We then develop a plan to mitigate all the issues and realize the opportunities to deliver a successful project. On this project the first major schedule hurdle is completing the irrigation work prior to March 31, 2022. There is a substantial amount of work to complete in a short window. We understand the critical nature of this work and the impact irrigation has on the farming community and the economy of Weld County. Our approach, as detailed in the provided schedule, is to begin the irrigation work as soon as possible after NTP 1. Construction of the cast -in -place box culvert will be the first priority as this activity is critical to achieving the irrigation milestone. As this work will be completed during the winter months, we have included cold weather protection for all concrete structures to maintain the schedule and quality of the project. Simultaneously, IHC Scott will begin placing the RCP for the Bliss Ditch, grading the Eaton Draw alignment south of the box culvert, building the slope and ditch paving, and completing the diversion structure for the Divide Ditch. Once the road is closed Bliss Ditch flows will be diverted to Eaton draw, utilizing temporary pipe, to complete this system. Additionally, the remainder of the drainage and irrigation facilities will be completed to meet the March 31 deadline. When the intersection closes, IHC Scott will begin work to complete the roadway grading and paving while completing the irrigation activities. This will begin with removals of the existing roadway and continue with completing the embankment and base activities for the road. Our paving crew will arrive on site once the base is complete and will work almost entirely on this project until the paving is complete. Our asphalt subcontractor will then be mobilized to complete the tie ins and the driveways while the other project finishes are being completed. Our proposed schedule, on the following pages, accounts for all activities needed to construct the project, lays them out in a logical manner and provides a clear path to complete the project in the allotted time.

These stakeholders include residents within the project limits, local farmers, irrigation companies, oil and gas companies and the local residents who travel the roadways. Maintaining access to these stakeholders throughout the project and keeping them up to date on the progress and changes they will experience will be essential to overall success. We will begin the process upon award of the contract. Our staff will reach out to land owners to begin to acclimate them to our plan and to discuss our plan to keep access into their properties during the construction of the project. These interactions will allow us to gather information about their needs and adjust the plan as necessary to meet these needs. Our staff wilt also meet with the irrigation companies to discuss our plans with them as well as to understand their schedule. From our past experience, we understand that the dates in which water is needed to be released for irrigation is a floating target in lieu of a hard and fast date. Through regular coordination with the irrigation companies we will know their needs and can adjust accordingly to reduce or eliminate any impacts to their system, should the need for water be earlier. Prior to and throughout the full closure of the intersection, IHC Scott will deliver updates to the impacted stakeholders to keep them informed of how the construction will impact them and how IHC Scott will mitigate these impacts. We will perform as much of this communication as we can in person. It has been our experience that relationships with local stakeholders are much better when a person can put a face to a name. This personal approach provides accountability and gives the stakeholders assurance their needs are met. COMMUNICATION Open and honest communication is crucial to the success of any project. This will be especially true on this project given the amount of work to be completed and the short time lines in which to complete the project. IHC Scott will have a dedicated staff on site led by our Project Manager, Jeff Meyer. Tyson Kincaid will also be onsite in the Superintendent role. Additional support will be provided by Cameron Thompson, our Operations Manager. These individuals are all presently completing the work on the 35th Avenue and 0 Street Roundabout for Weld County. This will benefit the project and Weld County as our staff already has a working relationship with County staff, understand the County's needs, and will be able to effectively communicate and solve issues as a team. Our Project Manager and Superintendent will be onsite throughout the duration of the project to foster an environment which enables regular communication to keep all parties aware of the project status and needs. We will communicate schedule updates during our weekly meetings and also in person with affected stakeholders. These schedule updates will provide our plan for the coming weeks and will give the project team an opportunity to look ahead at potential issues and work towards mitigating these issues. Our project staff is adept at communicating with owners and the following three projects are examples of success they have had on other recent projects, some individually and some as a team. Our word is our bond and we will carry this value to this project and ensure we work together as a team to successfully complete this project.

Howard Pl., Denver, CO (303) 512-4272 CR 66 AND CR 41 INTERSECTION Project #B2200115 SCOPE OF PROPOSAL METHODOLOGY IRRIGATION AND DRAINAGE IHC Scott wilt self perform the vast majority of the irrigation work on the project, including the concrete structures. This will allow us more control over the quality and the schedule of these activities. We wilt mobilize our structures and underground crews at NTP 1 to begin this work as soon as possible. Our structure crews wilt focus on the cast -in -place box culvert first as this structure is the most time consuming. Crews wilt form and pour as much of the floor, walls, deck and north headwall as is available in the first phase. The remainder for the box culvert floor, watts, deck, and south headwall wilt be installed once the roadway is closed. This work along with all the other structures on the project will be performed by IHC Scott crews and the Class D concrete will be supplied from our own plant, giving us tighter control over the schedule and quality of the final product. While floor and wall placements on the CIP box culvert are curing, crews will move to the other structures available in Phase 1. This wilt include the southern diversion structure in the Divide Ditch. While the phasing plans indicate this area isn't available until Phase 2, the new structure is further south than the existing and outside the clear zone, giving IHC Scott the ability to complete this structure earlier and allow the pipe to be placed from the outflow towards the inflow. The remaining structures will be phased in during curing periods, once these 2 main structures are completed. As work is proceeding on the concrete structures, IHC Scott underground crews will begin work on the Bliss Ditch Pipe installation, as well as the other available systems. The pipe wilt be placed from the southern terminus north to the point at which the pipe crosses the existing ditch. Once the roadway is closed, IHC Scott will divert the flows in the ditch away from the remaining pipe installation. This water wilt be carried in temporary pipe from the northern limits of the construction to the south end of the project. This will keep the water clean and not allow any potential run-off from the project to enter the irrigation system. The new alignment of the Eaton Draw will begin as soon as possible after NTP 1. Completing this work early will aid the project by helping to maintain drainage, as welt as give the project a path in which to place the temporary pipe for the Bliss Ditch diversion. These same grading crews will also work preparing all the ditches for the slope and ditch paving to ensure completion by March 31. IHC Scott will produce all the Class D, flowfill and concre and ditch paving for the project from our own batch plant, p schedule certainty and a high quality product. r PHASING IHC Scott has identified areas in which the phasing can be amended to expedite the construction. The first of which is the construction of the diversion structure at the Divide Ditch. This structure can be completed off-line and outside the roadway and clear zone with no traffic control. By constructing this portion of Divide Ditch first, IHC Scott can start at the outflow and get this elevation set correctly first, prior to placing any pipe. This improves the quality of the build, while helping keep the Divide Ditch activities off the critical path of the project. Other areas for opportunity to complete work sooner include: • Working with the local stakeholders to provide alternate access to install the pipe and work on the grading of their driveways in Phase 1. • Completing the construction of the turnarounds required for the full closure early. i/i WEIc§COIL 7 CR 66 AND CR 41 INTERSECTION Project #B2200115 SCOPE OF PROPOSAL METHODOLOGY PAVING PLAN IHC Scott has built our reputation on providing high quality, cost effective concrete pavements for our owners. We are experts at analyzing jointing and building a paving plan that optimizes the efficiency of the paving process. When the plan is efficient, the amount of pavement placed by machine is maximized which creates a smoother higher quality pavement as well as a more schedule friendly approach. We have followed this approach on this project and have developed a plan that maximizes the amount of machine paving, and provides the most cost effective approach for the County. Our proposed plan will split the 50 foot roadway on CR 66 and CR 41 into two 25 foot machine placements, as shown in green. By maximizing the amount of machine paving and completing the full width of the roadway in two passes, we are able to provide a smoother, higher quality pavement. The remainder of the pavement, shown in orange, will be placed by hand, with the odd shaped panels reinforced with wire mesh as required.

Mil IHC SCOTTJ 8 CR 66 AND CR 41 INTERSECTION Project #B2200115 CRITICAL ISSUES AND RESOLUTIONS As in any construction project, issues will appear that have the potential to impact the schedule or cost. Early identification, timely communication and proper mitigations are crucial to resolving potential hurdles before they become catastrophic. IHC Scott has identified some critical issues to the success of this project. These issues include, but are not limited to: • Schedule Adherence • Critical Supply Chain Issues • Environmental Compliance • Unsuitable Soils • Access During Construction IHC Scott understands these issues exist and have begun the process of finding solutions to the issues and have included those resolutions in this proposal. SCHEDULE ADHERENCE CRITICAL SUPPLY CHAIN ISSUES It is no secret that the schedule for the completion of this project is tight, particularly in regard to the irrigation work. Our plan as presented in this proposal provides an efficient and effective approach to the work which meets the project's scheduling needs. IHC Scott will monitor this schedule throughout the life of the project and will update the county regularly on the progress through daily communications with our counterparts at Weld County, 3 week schedule updates and immediate notifications on issues that arise which may cause a schedule impact. This approach will allow IHC Scott and Weld County as a team to mitigate any potential schedule issues for the betterment of the project. In addition, IHC Scott has a multitude of resources throughout the Front Range, that can be called upon to supplement the crews assigned to this project to meet any schedule need. The current state of inflation and lack of materials has created supply chain issues throughout the construction industry. This is especially true with the ready mix market. Ready mix suppliers are met with challenges of a lack of material to produce their product. This has caused these suppliers to begin to ration the amount of concrete they can deliver in a single day and the number of days they will service a single customer. IHC Scott is able to combat this issue by utilizing our plant for the production of our concrete. On this project IHC Scott will batch the concrete for all the paving from our own plant. Our relationships with the cement suppliers and our preplanning have allowed us to weather this storm and keep our stockpiles up to meet our project needs. We will also batch our own ready mix from our plant for the RCBC, slope and ditch paving, CIP structures and flowfill on this project. This will give us complete control over the delivery of the over 250 loads of structural concrete we will need for the project. Another industry that is affected is the precast and pipe supply. This industry currently has increased the lead time for these products, specifically specialty products like elliptical pipe. Proper preplanning and scheduling reduces this impact and makes sure products are received timely. Our relationships with the suppliers also put us in a position where we are pushed to the front of the production line, so we can receive the materials ahead of our competitors. [IHc SCOTT 9 CR 66 AND CR 41 INTERSECTION Project #B2200115 CRITICAL ISSUES AND RESOLUTIONS ENVIRONMENTAL COMPLIANCE There is a significant amount of work involving irrigation and drainage facilities on this project. Working within and near these waterways creates a discharge potential for the project. In addition, water runs in the Eaton Draw/Bliss Ditch year round, creating the need to divert these flows to complete the work. IHC Scott wilt mitigate this by utilizing Best Management Practices and creating and maintaining a solid environmental compliance plan. Our Corporate Environmental Compliance Officers have already visited the site and have developed the initial plan for this project. Key highlights of the plan include: • Diversion of the water in the Eaton Draw/Bliss Ditch will be piped throughout the project limits eliminating the potential for runoff from the jobsite to enter the water. • IHC Scott utilizes an environmental software (ComplianceGO) for all projects requiring stormwater permits (local and/or State). ComplianceGO helps track, schedule, and manage inspections and action items related to stormwater programs. • In September of 2021, IHC Scott was recognized by the Colorado Environmental Leadership Program as a Gold Leader. Our proven track record shows we are conscious stewards of the environment. COLORADO Environmental Leadership R-17 SOIL AVAILABILITY Based on the geotechnical report, the existing soils have an R -Value of 17, with the exception of bore holes BH-2 and BH-6. IHC Scott will perform further geotechnical analysis of these areas to further define the limits of available soils within the project limits. We have identified a source near the jobsite with soils meeting the criteria needed for the project. The close proximity of the borrow site equates to shorter truck hauls and a lower cost to the project overall. ACCESS DURING CONSTRUCTION Throughout the duration of the project, local access will be impacted to businesses, farmers and residents. It is imperative that safe and easily traversable access is maintained to the stakeholders. IHC Scott has developed a plan to provide this access and will work with the local stakeholders to ensure the plan meets their needs. We will coordinate with them throughout the project to keep them up to date on the progress of the work and to address any issues they may have. Our on site Superintendent will monitor these accesses daily to ensure they are maintained and kept in good working order, including snow removal after winter storms.. OUR COMMITMENT We understand there are many other critical issues to the project beyond what we have listed above. These issues have been highlighted because, based our past experience with Weld County and this specific location, we believe these issues are unique to this project are likely not considered by others who do not have the same experience we do. We are committed to meeting the County's goats on this project and will partner, as we have before, to mitigate any and all additional issues that may arise. sr IHC scott) 10 CR 66 AND CR 41 INTERSECTION Project #B2200115 PROJECT CONTROL Our extensive background with Weld County has given us insight on the needs of the County and this project. Our project control approach begins with understanding the needs of the project and transparently working as a team towards meeting those needs. We will use this knowledge to successfully manage the project as detailed below. CONSTRUCTION COST CONTROL IHC Scott provides the best value to Weld County for the CR 66 and CR 41 Intersection. We accomplish this by understanding and monitoring the budget, quantities and schedule to identify and mitigate potential hurdles. We strive to be the contractor of choice for our owners and a main component of this is our partnering approach. This has been key to building our relationship with Weld County. As issues arise that could potentially affect the project budget or schedule, we openly communicate the issue and work with the County to identify the most cost effective solution, while maintaining the overall project quality and schedule. Prioritizing the needs of the project above the needs of individual parties assures that the right solution is identified and implemented for any issue that may arise. Our approach encourages a true partnership on the project, strengthened by regular communication with Weld County personnel. We encourage all of our project team to meet with County staff at regular intervals. This practice enhances communication and galvanizes the true partnering culture. mar COMMITMENT TO CONFLI RESOLUTION It is our commitment that resolu of issues is best settled at the to level possible on the pro' aft 7 IHC SCOTT) SUBCONTRACTOR COST CONTROL We engage our subcontractors early through the bidding process to identify scope packages aligned with their capabilities and make them an integral part of our team. As the project progresses our subcontractors are heavily involved in our planning process to ensure full understanding of the project needs by all parties. Thus, our subcontractors fully understand the scope, schedule and quality requirements and are setup for success on the project.

Four of the five commissioners approved the pass around to be place on the Board's agenda. On July 14, 2022, the BOCC approved a pass around allowing Public Works to use the Best Value bidding process that is outlined in Chapter 5, Article 5-4-40 of the Weld County Code. The Best Value bidding process considers a bidder's qualifications in addition to price. The Request for Qualifications (RFQ) for the CR 66 and CR 41 Intersection Project was advertised on July 29, 2022 in the Greeley Tribune and on BidNet Direct. Three RFQs were received on August 15, 2022 and were presented to the BOCC an August 17, 2022. In accordance with Chapter 5, Article 5-4-40 of the Weld County Code, Public Works and Purchasing reviewed the RFQs and shortlisted 2 of the 3 bidders. The shortlisted bidders were provided the Request For Proposal (RFP). Proposals were received on September 26, 2022 and interviews were held with the bidders on October 5, 2022. Following the interviews, the bidders were allowed to provide a Best and Final Offer (BAFO). The BAFO responses were opened on October 20, 2022. The submitted proposals were reviewed for errors and completeness. There were no errors in the proposals The bid tabulation is included with this document. The submitted proposals met all bidding requirements and met all of the Weld County Code requirements. The engineer's estimate for the project was $12,667,391.25. H -IC -Scott's bid price for the project was $12,821,742.91. Structure Inc's bid price was 12,423,928.93. IHC-Scott was within 1.22% of the engineer's estimate and Structures was within 1.9% of the engineer's estimate. Based on the Best Value Scoring Tables from the Weld County Code, the bidder whose combined proposal/BAFO and interview scores represented the Best Value was IHC-Scott. Public Works has budgeted for this project in its 2022 and 2023 budgets. Public Works recommends awarding the construction contract to, IHC-Scott for a total amount not to exceed $12,821,742.91 Construction is anticipated to commence in November, 2022 and is planned to be completed by July 31, 2023.

Public Works and Purchasing reviewed the RFQs and shortlisted 2 of the 3 bidders on August 22. The shortlisted bidders were provided the Request For Proposal (RFP) on August 29. The bidders provided their proposals including costs on September 26. Following the review of the proposals, the bidders were invited to an interview with the review committee to present their project approach and answer questions that the County had regarding the proposals and bids. The interviews were held on October 5. After the interviews, it was apparent to the County that several items in the bid needed to be further clarified. As a result, it was decided to proceed to the Best and Final Option (BAFO) phase of the bidding process. The items needing more information were clarified and the bidders were given the opportunity to revise their bids to account for the new information. The bids from the BAFO were opened on October 20. The scoring process used in the selection of the bidder representing the best value to the County is summarized in the attached documents. The bidder's proposals were reviewed using 5 different weighted categories representing a maximum of 100 points. The bidder's qualifications, work approach, critical issues, and familiarity with Weld County represent 60% of the RFP score and cost/schedule represents 40% of the RFP score. The interviews were scored using 4 weighted categories representing 100 points. The total number of points available equals 100. The BAFO pricing is substituted back into the scoring matrix to get a new RFP score for the cost/schedule category. The total scores are ranked from high to low with the highest score being assigned a rank of 1. Each reviewer's rank is then summed to get an aggregate ranking. For this project, IHC-Scott was ranked as number 1 by all 5 reviewers for a total score of 5. Structures Inc. was ranked as number 2 by all 5 reviewers for a total score of 10. The bidder with the lowest score represents the best value to the County. The engineer's estimate for the project was $12,667,391.25. IHC-Scott's bid price for the project was $12,821,742.91. Structure Inc's bid price was 12,423,928.93. IHC-Scott was within 1.22% of the engineer's estimate and Structures was within 1.9% of the engineer's estimate. IHC-Scott represents the best value for the County because they plan to provide all the concrete required for the project from their own batch plant which will be less than 1 mile from the project. Having their own plant setup allows IHC-Scott to maintain a high quality of concrete for the project. The use of their own plant also reduces the risk of having schedule delays due to quantity limitations which have plagued contractors throughout 2022. The result of having their own batch plant is shown in IHC-Scott's bid because it is approximately $398,000 higher than Structure Inc's bid. Structures Inc is proposing to haul all the concrete including the concrete required for paving from Martin Marietta's concrete batch plant on CR 13. Structures Inc will not have exclusive use Martin Marietta's batch plant and will be impacted by quantty limitations which have plagued contractors throughout 2022. The quantity limitations at a third party batch plant are not expected to decrease in 2023 due to supply chain issues and the lack of qualified delivery drivers. What options exist for the Board? (include consequences, impacts, costs, etc. of options): 1. The Board can opt to award the construction contract for the CR 66 and CR 41 project to IHC-Scott because they represent the best value to Weld County after all factors are considered. The risk associated with schedule delays is minimized by having a Contractor who can control their production of concrete and is not subject to the quantity limitations of a third party batch plant. 2. The Board can request a work session to further discuss these bids. Recommendation: Public Works recommends Option 1 which is to award the construction contract to IHC-Scott because they represent the best value to the County. Public Works has budgeted money in the 2022 and 2023 budgets to cover awarding the contract to IHC-Scott without asking for a supplemental budget increase. The contract would be done using Notice to Proceed 1 (NPT1) in the amount of $2,000,000 in 2022 and NPT2 in the remaining amount for 2023. Public Works has coordinated with Don Warden and he is in concurrence with our recommendation. Perry L. Buck Mike Freeman, Pro-Tem Scott K.
