The IRS has created a page on IRS.gov for information about Form W-9, at www.irs.gov/w9. Information about any future developments affecting Form W-9 (such as legislation enacted after we release it) will be posted on that page. Purpose of Form A person who is required to file an information return with the IRS must obtain your correct taxpayer identification number (TIN) to report, for example, income paid to you, payments made to you in settlement of payment card and third party network transactions, real estate transactions, mortgage interest you paid, acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA. Use Form W-9 only if you are a U.S. person (including a resident alien), to provide your correct TIN to the person requesting it (the requester) and, when applicable, to: 1. Certify that the TIN you are giving is correct (or you are waiting for a number to be issued), 2. Certify that you are not subject to backup withholding, or 3. Claim exemption from backup withholding if you are a U.S. exempt payee. If applicable, you are also certifying that as a U.S. person, your allocable share of any partnership income from a U.S. trade or business is not subject to the withholding tax on foreign partners' share of effectively connected income, and 4. Certify that FATCA code(s) entered on this form (if any) indicating that you are exempt from the FATCA reporting, is correct. Note. If you are a U.S. person and a requester gives you a form other than Form W-9 to request your TIN, you must use the requester's form if it is substantially similar to this Form W-9. Definition of a U.S. person. For federal tax purposes, you are considered a U.S. person if you are: • An individual who is a U.S. citizen or U.S. resident alien, • A partnership, corporation, company, or association created or organized in the United States or under the laws of the United States, • An estate (other than a foreign estate), or • A domestic trust (as defined in Regulations section 301/701-7). Special rules for partnerships. Partnerships that conduct a trade or business in the United States are generally required to pay a withholding tax under section 1446 on any foreign partners' share of effectively connected taxable income from such business. Further, in certain cases where a Form W-9 has not been received, the rules under section 1446 require a partnership to presume that a partner is a foreign person, and pay the section 1446 withholding tax. Therefore, if you are a U.S. person that is a partner in a partnership conducting a trade or business in the United States, provide Form W-9 to the partnership to establish your U.S. status and avoid section 1446 withholding on your share of partnership income.

October 4, 2023 10 REVISION OF SECTION 106 CONTROL OF MATERIAL 8 Reporting and Record Keeping. The Contractor shall report the results of the process control tests to the Engineer in writing at least once per day. The Contractor shall assemble a process control (PC) notebook and update it daily. This notebook shall contain all worksheets, test results forms, test results charts and quality level charts for each of the elements listed in Table 106-2. The Contractor shall submit the PC notebook to the Engineer for review once a month on the date agreed to at the Pre -Paving Conference. The PC notebook will be returned to the Contractor within one working day after submittal. The Engineer will notify the Contractor in writing of any deficiencies in the PC notebook, including the failure to submit the notebook on time or an absence of the required reports. Upon the second failure to submit the complete PC notebook on time or with an absence of the required reports, the Engineer will notify the Contractor, and the pay estimate will be withheld until the Contractor submits, in writing, a report detailing the cause for the failure to submit the complete PC notebook on time or the cause for the absence of required reports. The report shall include how the Contractor plans to resolve the failures. Additional failures to submit the PC notebook on time or absent the required reports will result in a delay of the pay estimate until the Contractor has identified and resolved the failure along with revising and resubmitting his PCP to address these issues. Once the Engineer has reviewed and approved the revised PCP the estimate may be paid. Upon submittal of the PC notebook for the semi-final estimate, the PC notebook shall become the property of the Department. The Contractor shall make provisions such that the Engineer can inspect process control work in progress, including PC notebook, sampling, testing, plants, and the Contractor's testing facilities at any time. After compaction of the HMA is completed, in -place density tests for process control shall be taken at the frequency shown in Table 106-2. The results shall be reported in writing to the Engineer on a daily basis. Daily plots of the test results with tonnage represented shall be made on a chart convenient for viewing by the Engineer. All of the testing equipment used for in -place density testing shall conform to the requirements of acceptance testing standards, except nuclear testing devices need not be calibrated on the Department's calibration blocks. (b) Acceptance Testing. Acceptance testing is the responsibility of the Department and shall not be addressed in the PCP. The Department will determine the locations where samples or measurements are to be taken and as designated in Section 403. The maximum quantity of material represented by each test result, the elements, the frequency of testing and the minimum number of test results will be per Table 106-2. The location or time of sampling will be based on the stratified random procedure as described in CP 75. Acceptance sampling and testing procedures shall be per the Schedule for Minimum Materials Sampling, Testing and Inspection in the CDOT Field Materials Manual. Samples for project acceptance testing shall be taken by the Contractor per the designated method. The samples shall be taken in the presence of the Engineer. Where appropriate, the Contractor shall reduce each sample to the size designated by the Engineer. The Contractor may retain a split of each sample which cannot be included as part of the Contractor's process control testing. If the Contractor elects to question the Hot Mix Asphalt (HMA) acceptance test results, the steps outlined in CP 17 shall be followed. Dispute of the acceptance test results per CP-17 shall not be allowed unless the CP-13 Check Test Program has been successfully completed. The Contractor shall initiate, coordinate, and complete a successful Check Testing Program with the OA tester before HMA placement. The results from the CP 17 resolution process shall be binding on both the Department and the Contractor. Requests for CP 17 process for all elements except density shall be submitted in writing to the Engineer within five workdays from the date the Contractor receives acceptance test data from the Engineer. The specific element questioned shall be identified in writing. All requests for the CP 17 process for the density element shall be submitted in writing to the Engineer within 24 hours of receiving test data from the Engineer. 100 October 4, 2023 11 REVISION OF SECTION 106 CONTROL OF MATERIAL The Contractor shall choose a consultant laboratory not associated with the project from the CDOT pre- established list to perform the third party testing. The Contractor shall document his choice in writing at the Pre -Paving Conference. The Department shall determine the consultant has no conflict of interest. If third party testing is required, the responsibility for the testing expenses shall be assigned per CP 17. The costs for testing are shown in CP 17, Table 17-2. All materials being used are subject to inspection and testing at any time before, during, or after incorporation into work. Acceptance tests will be made by and at the expense of the Department except when otherwise provided. (c) Check Testing Program (CTP). Before, or in conjunction with, placing the first 500 tons of asphalt pavement, under the direction of the Engineer, a CTP will be conducted between acceptance testing and process control testing programs. The CTP will consist of testing for asphalt content, theoretical maximum specific gravity, HMA 4.75 mm (#4) sieve, HMA 2.36 mm (#8) sieve, HMA 0.075 mm (#200) sieve, in -place density, and joint density per CP 13. If the Contractor intends to test to determine air voids and VMA, check testing for these tests is recommended. The CTP will be continued until the acceptance and process control tests are within the acceptable limits shown in Table 13-1 of CP 13. For joint density, the initial check test will be a comparison of the seven cores tested by CDOT and the seven cores tested by the Contractor. These are the cores from the compaction test section used for nuclear gauge calibration and test section payment. During production, a split sample check will be conducted at the frequency shown in Table 106-2. Except for joint density, the split samples will be from an acceptance sample obtained per subsection 106.05(b). The acceptance test result will be compared to the process control test result obtained by the Contractor using the acceptable limits shown in Table 13-1 of CP 13. For joint density, the comparison sample for testing by the Contractor will be obtained by taking a second core adjacent to the joint density acceptance core. The acceptance test result will be compared to the process control test result obtained by the Contractor using the acceptable limits as shown in Table 13-1 of CP 13 and following the check testing procedure given in CP 13. If production has been suspended and then resumed, the Engineer may order a CTP between process control and acceptance testing persons to assure the test results are within the acceptable limits shown in Table 13-1 of CP 13. Check test results shall not be included in process control testing. The Engineer shall be called upon to resolve differences if a CTP shows unresolved differences beyond the values shown in Table 13-1 of CP 13. (d) Stability Verification Testing. After the mix design has been approved and production commences, the Department will perform a minimum of three stability verification tests to verify that the field produced HMA conforms to the approved mix design: The test frequency shall be one per day unless otherwise directed by the Engineer. The test results will be evaluated, and the Contractor shall make adjustments if required per the following: 1. The minimum value for stability will be the minimum specified in Table 403-1 of the specifications. There will be no tolerance limit. 2 Quality Level. Calculate a QL for stability. If the QL for stability is less than 65, then production shall be halted, and the Contractor shall submit a written proposal for a mix design revision to the Engineer. The Engineer shall give written approval to the proposed mix design revision before production continues. 101 October 4, 2023 12 REVISION OF SECTION 106 CONTROL OF MATERIAL After a new or revised mix design is approved, three additional stability tests will be performed on asphalt produced with the new or revised mix design. The test frequency shall be one per day unless altered by the Engineer. If the stability QL is less than 65, then production shall be halted until a new mix design has been completed and approved using plant produced material or the Contractor shall submit a written proposal for a mix design revision to the Engineer. The Engineer shall give written approval to the proposed mix design revision before production continues. 3 New or Revised Mix Design. Whenever a new or revised mix design is used and production resumes, three additional stability field verification tests shall be performed, and the test results evaluated per the above requirements. The test frequency shall be one per day unless altered by the Engineer. 4 Field Verification Process Complete. When the field verification process described above is complete and production continues, the sample frequency will revert back to 1 per 10,000 tons. e) Mix Verification Testing. After the mix design has been approved and production commences, the Department will perform a minimum of three volumetric verification tests for each of the following elements to verify that the field produced hot mix asphalt conforms to the approved mix design: (1) Air Voids (2) Voids in Mineral Aggregate (VMA). (3) Asphalt Content (AC). The test frequency shall be one per day unless altered by the Engineer. The test results will be evaluated, and the Contractor shall make adjustments if required per the following: 1. Target Values. The target value for VMA will be the average of the first three volumetric field test results on project produced hot mix asphalt or the target value specified in Table 403-1 and Table 403-2 of the specifications, whichever is higher. The target value for VMA will be set no lower than 0.5 percent below the VMA target on Form 43 before production. The target values for the test element of air voids and AC shall be the mix design air voids and mix design AC as shown on Form 43. 2 Tolerance Limits. The tolerance limits for each test element shall be: AC ± 0.3 percent Air Voids ± 1.2 percent VMA ± 1.2 percent 3 Quality Levels. Calculate an individual QL for each of the elements using the volumetric field verification test results. If the QL for VMA or AC is less than 65 or if the QL for air voids is less than 70, the production shall be halted, and the Contractor shall submit a written proposal for a mix design revision to the Engineer. Production shall only commence upon receipt of written approval from the Engineer of the proposed mix design revision. After a new or revised mix design is approved, three additional volumetric field verification tests will be performed on asphalt produced with the new or revised mix design. The test frequency shall be one per day unless altered by the Engineer. 102 October 4, 2023 13 REVISION OF SECTION 106 CONTROL OF MATERIAL If the QL for VMA or AC is less than 65 or the QL for the test element of air voids is less than 70, then production shall be halted until a new mix design has been completed per CP 52 or CP 54, a new Form 43 issued, and the Contractor demonstrates that he is capable of producing a mixture meeting the verification requirements per A or B below: A. The Contractor shall produce test material at a site other than a Weld County project. The Contractor shall notify the Engineer a minimum of 48 hours before the requested test. The location and time of the test are subject to the approval of the Engineer before placement. Three samples will be tested for volumetric properties. If the QL for VMA or AC is equal or greater than 65 and the QL for the element of air voids is equal or greater than 70, full production may resume or; B The Contractor may construct a 500 ton test strip on the project. Three samples in the last 200 tons will be tested for volumetric properties. After construction of the test section, production shall be halted until the testing is complete and element QLs are calculated. If the QL for VMA or AC is equal or greater than 65 or the QL for the element of air voids is equal or greater than 70, full production may resume. If the QL for VMA or AC is less than 65 or the QL for the element of air voids is less than 70, the material shall be removed and replaced at no cost to the Department. The time count will continue, and any delay to the project will be considered to have been caused by the Contractor and will not be compensable. The costs associated with mix designs shall be solely at the Contractor's expense. If the Contractor fails to verify the new mix design per A or B, then production shall be halted until a new mix design has been completed per CP 52 or CP 54, a new Form 43 issued, and the Contractor demonstrates they are capable of producing a mixture meeting the verification requirements per A or B. 4 New or Revised Mix Design. Whenever a new or revised mix design is used and production resumes, three additional volumetric field verification tests shall be performed, and the test results evaluated per the above requirements. The test frequency shall be one per day unless altered by the Engineer. Field Verification Process Complete. When the field verification process described above is complete and production continues, the sample frequency will revert back to a minimum of 1/10,000 tons. The Engineer has the discretion to conduct additional verification tests at any time. Testing Schedule. Process control and project acceptance testing frequency shall be per Table 106-2. Reference Conditions. Three reference conditions can exist determined by the Moving Quality Level (MQL). The MQL will be calculated per the procedure in CP 71 for Determining Quality Level (QL). The MQL will be calculated using only acceptance tests. The MQL will be calculated on tests 1 through 3, then tests 1 through 4, then tests 1 through 5, then thereafter on the last five consecutive test results. The MQL will not be used to determine pay factors. The three reference conditions and actions that will be taken are described as follows: 1. Condition green will exist for an element when an MQL of 90 or greater is reached, or maintained, and the past five consecutive test results are within the specification limits. 2 Condition yellow will exist for all elements at the beginning of production or when a new process is established because of changes in materials or the job -mix formula, following an extended suspension of work, or when the MQL is less than 90 and equal to or greater than 65. Once an October 4, 2023 14 REVISION OF SECTION 106 CONTROL OF MATERIAL element is at condition green, if the MQL falls below 90 or a test result falls outside the specification limits, the condition will revert to yellow or red as appropriate. 3 Condition red will exist for any element when the MQL is less than 65. The Contractor shall be notified immediately in writing and the process control sampling and testing frequency increased to a minimum rate of 1/250 tons for that element. The process control sampling and testing frequency shall remain at 1/250 tons until the process control QL reaches or exceeds 78. If the QL for the next five process control tests is below 65, production will be suspended. If gradation is the element with MQL less than 65, the Department will test one randomly selected sample in the first 1250 tons produced in condition red. If this test result is outside the tolerance limits, production will be suspended. (This test result will not be included as an acceptance test.) After condition red exists, a new MQL will be started. Acceptance testing will stay at the frequency shown in Table 106-2. After three acceptance tests, if the MQL is less than 65, production will be suspended. Production will remain suspended until the source of the problem is identified and corrected. Each time production is suspended, corrective actions shall be proposed in writing by the Contractor and approved in writing by the Engineer before production may resume. Upon resuming production, the process control sampling and testing frequency for the elements causing the condition red shall remain at 1/250 tons. If the QL for the next five process control tests is below 65, production will be suspended again. If gradation is the element with MQL less than 65, the Department will test one randomly selected sample in the first 1250 tons produced in condition red. If this test result is outside the tolerance limits, production will be suspended.

Topsoil which has been stripped and stockpiled shall be placed on the top of embankment slopes. Materials incorporated into embankment fill shall be placed and compacted according to the following requirements: Subsection 203.07(a) shall be deleted and replaced with the following: (a) Soil Embankment. All soil embankment shall be placed in horizontal layers not to exceed 8 inches in loose lift thickness. Each layer shall be compacted before the placement of subsequent layers. Spreading equipment shall be used to obtain uniform thickness before compaction. As the compaction progresses, continuous mixing, leveling, and manipulating shall be done to assure uniform moisture and density. Additional work involved in drying soil embankment to the required moisture content shall be included in the contract price paid for excavating or furnishing the material with no additional compensation. When conduits (i.e., culverts, pipes, etc.) are installed in embankment material, the embankment shall first be constructed to a required height of a minimum of one foot above the top of conduit and for a distance on each side of the conduit of at least 5 times the diameter or span of the conduit, after which the trench shall be excavated and the conduit installed. Before trench excavation, the embankment material shall pass the compaction requirements for the Project. Soil embankment that is classified as A-1 material may be used to bridge across standing water or swampy ground within the embankment foundation and may be placed in lift thicknesses greater than 8 inches when used for this purpose if approved by the Engineer. A Sheepsfoot compactor shall not be used on A-1 material containing less than 30% retained on the 3/4 -inch sieve.

Sheepsfoot rollers are appropriate for materials composed of cohesive soils and clay rich non -durable bedrock. Soil embankment with less than or equal to 30% retained on the 3/4 -inch sieve shall be tested for compaction using CP-80. Materials classified as AASHTO A-1, A-2-4, A-2-5, and A-3 soils shall be compacted at +/- 2 percent of optimum moisture content (OMC) and to at least 95 percent of maximum dry density determined per AASHTO T180, modified by CP-23. All other soil types are compacted to 95 percent of maximum dry density determined per AASHTO T99, modified by CP-23. Soils with 35 percent fines or less are compacted at +/- 2 percent of OMC. Soils with more than 35 percent fines are compacted at a moisture content equal to or above OMC to achieve stability of the compacted lift. Stability is defined as the absence of rutting or pumping as observed by the Contractor's Process Control representative and as approved by the Engineer. If the soils prove to be unstable when compacted at or above optimum moisture content, the moisture content required for compaction may be reduced below OMC as approved by the Engineer. Compaction shall be tested using nuclear density gauges (CP-80-13) at the frequencies specified in Table 106-1. Compaction tests shall be performed in accordance CP-80 and shall utilize 4 one -minute readings. The use of 1 fifteen -second test shall be not acceptable for Process Control testing.

The test sites shall be selected randomly and shall be representative of the materials placed in the surrounding areas. The Contractor shall provide a stable platform on which the one -point tests can be performed. Any time a density verification test is over 100%, a field one point moisture/density verification test and a field rock correction test shall be performed to verify the use of the correct proctor. 133 October 19, 2023 4 REVISION OF SECTION 203 EXCAVATION AND EMBANKMENT Before placing any soil embankment with greater than 30 percent retained on the 3/4 -inch sieve, the Contractor shall construct a test strip to the dimensions specified in the Contract or as directed by the Engineer. The test strip may be incorporated into the final embankment. The Contractor shall determine the moisture conditioning necessary to achieve compaction and shall determine the equipment and number of passes necessary to achieve adequate compaction. The Contractor shall use compression -type or vibratory rollers on granular materials and sheepsfoot rollers on cohesive soils. Adequate compaction shall be demonstrated by the absence of rutting, pumping, or deflection following a proof roll of the test strip using any piece of construction equipment that exerts a minimum 18 -kip per axle load. The proof roll will be observed and accepted by the Engineer. Once the test strip passes a proof roll, the Contractor may resume embankment construction using the same moisture conditioning and compaction methods that were used to construct the test strip.

The Contractor shall submit a method statement for subgrade soil preparation. The Contractor shall calibrate the subgrade soil preparation equipment using a minimum 30 linear feet of the initial pass. The Contractor shall utilize the rod penetrometer to verify that that de -compaction was successfully done. 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 or the depth shown on the plans 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 and deeper placement will not negatively impact stormwater drainage patterns, at the sole discretion of the Engineer. 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 144 October 4, 2023 6 REVISION OF SECTION 207 TOPSOIL 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 the topsoil thickness shown on the plans.

Stormwater runoff from all disturbed areas and soil storage areas for which permanent or interim stabilization is not implemented, must flow to at least one control measure to minimize sediment in the discharge. This shall be accomplished through filtering, settling, or straining. The control measure shall be selected, designed, installed, and adequately sized in accordance with good engineering, hydrologic, and pollution control practices. The control measures shall contain or filter flows in order to prevent the bypass of flows without treatment and shall be appropriate for stormwater runoff from disturbed areas and for the expected flow rate, duration, and flow conditions (i.e., sheet or concentrated flow). The Contractor shall coordinate the construction and maintenance of temporary control measures with the construction of permanent control measures to assure economical, effective, and continuous erosion and sediment control throughout the construction period. The Initial Condition, Interim Condition, and Permanent Condition SWMP drawings are included with the plans for this project. The control measures shown on the Initial Condition and Interim Condition drawings shall be installed in a phased manner prior to the beginning of construction activities within various areas of the limits of construction. The Contractor shall be responsible for preparing and submitting an Erosion Control Phasing Plan which shows how the erosion and sediment control measures will be implemented to the Engineer for approval. Installation of the erosion control measures shall not begin until the Engineer has provided a written approval of the Erosion Control Phasing Plan. When a provision of Section 208 or an order by the Engineer requires that an action be immediate or taken immediately, it shall be understood that the Contractor shall at once begin affecting completion of the action and pursue it to completion in a manner acceptable to the Engineer, and in accordance with the Colorado Discharge Permit System Stormwater Construction Permit (CDPS-SCP) requirements. If immediate corrective actions cannot be taken, the Contractor shall immediately request a deferment by providing the information outlined in Section 208.09(c) for review by the Engineer.

The Contractor shall incorporate control measures into the project as outlined in the accepted schedule. (e) Stabilization. Once earthwork has started, the Contractor shall maintain erosion control measures until permanent stabilization of the area has been completed and accepted. Clearing, grubbing and slope stabilization measures shall be performed regularly to ensure final stabilization. Failure to properly maintain erosion control and stabilization methods, either through improper phasing or sequencing will require the Contractor to repair or replace sections of earthwork at the Contractor's expense. The Contractor shall schedule and implement the following stabilization measures during the course of the project: 1. Temporary Stabilization. At the end of each day, the Contractor shall stabilize disturbed areas by surface roughening, vertical tracking, or a combination thereof. Disturbed areas are locations where actions have been taken to alter the existing vegetation or underlying soil of a site, such as clearing, grading, roadbed preparation, soil compaction, and movement and stockpiling of sediment and materials. Designated topsoil distributed on the surface or in stockpiles shall not receive temporary stabilization. Other stabilization measures may be implemented, as approved. The maximum area of temporary stabilization (excluding areas of designated topsoil) shall not exceed 20 acres. 2 Interim Stabilization. Per Part I.B.2.a.iii of the CDPS-SCP, stabilization shall be implemented for earth disturbing activities on any portion of the site where ground disturbing construction has permanently ceased, or temporarily ceased for more than 14 days. Temporary stabilization methods may include, but are not limited to, tarps, soil tackifier, and hydroseed. The Contractor may exceed the 14 -day schedule when either the function of the specific area of the site requires it to remain disturbed or physical characteristics of the terrain and climate prevent stabilization. The SWMP shall document the constraints necessitating the alternative schedule, provide the alternate stabilization schedule, and identify all locations where the alternative schedule is applicable on the site map. Minimum inspection frequency and scope shall be followed for temporarily stabilized areas. As soon as it is known with reasonable certainty that work will be temporarily halted for 14 days or more, sediment and material stockpiles and disturbed areas shall be stabilized using one or more of the following methods: A. Application of 1.5 tons per acre of mechanically crimped certified weed free hay or straw in combination with an approved organic mulch tackifier. B Placement of bonded fiber matrix in accordance with Section 213. C. Placement of mulching (hydraulic) wood cellulose fiber mulch with tackifier, in accordance with Section 213. D. Application of spray -on mulch blanket in accordance with Section 213. Magnesium Chloride, Potassium Chloride, and Sodium Chloride or other salt products shall not be used as a stabilization method. E Topsoil stockpiles shall receive interim stabilization unless specified in accordance with 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. 169 October 4, 2023 24 REVISION OF SECTION 208 EROSION CONTROL 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 in accordance with Section 207. 5 Final Stabilization. Final stabilization is achieved when all ground -disturbing activities at the site have been completed, permanent stabilization methods are complete, temporary control measures are removed, 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. The vegetation coverage must be, at a minimum, equal to 70 percent of what would have been provided by native vegetation in a local, undisturbed area or adequate reference site. Once the CDPS-SCP is transferred, Weld County will be responsible for ensuring 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. Per Part I.B.1.a.iii.3.b of the CDPS-SCP, the Contractor must ensure that all control measures remain in effective operating condition and are protected from activities that would reduce their effectiveness. Control measures must be maintained in accordance with good engineering, hydrologic and pollution control practices. Erosion and sediment control practices and other protective measures identified in the SWMP as control measures for stormwater pollution prevention shall be maintained in effective operating condition until the CDPS-SCP has been transferred to Weld County. Control measures shall be continuously maintained in accordance with good engineering, hydrologic, and pollution control practices, including removal of collected sediment when silt depth is more than the effective height of the erosion control device shown in Section 208.05. When possible, the Contractor shall use equipment with an operator rather than labor alone to remove the sediment. Maintenance of erosion and sediment control devices shall include replacement of such devices upon the end of their useful service life as recommended by the Contractor and approved by the Engineer. Maintenance of rock check dams and vehicle tracking pads shall be limited to removal and disposal of sediment or addition of aggregate. Damages resulting from failure to maintain control measures shall be repaired at the Contactor's expense. Complete site assessment shall be performed as part of comprehensive inspection and maintenance procedures to assess the adequacy of control measures at the site and the necessity of changes to those control measures to ensure continued effective performance. Where site assessment results in the determination that new or replacement control measures are necessary, the control measures shall be installed to ensure continuous effectiveness. When identified, control measures shall be maintained, added, modified, or replaced as soon as possible, immediately in most cases. Approved new or replaced control measures will be measured and paid for in accordance with subsections 208.11 and 208.12. Devices damaged due to the Contractor's negligence shall be replaced at the Contractor's expense. From the time seeding and mulching work begins until project acceptance the Contractor shall maintain all seeded areas. Damage to seeded areas or to mulch materials shall be immediately restored. Damage to October 4, 2023 25 REVISION OF SECTION 208 EROSION CONTROL seeded areas or to mulch materials due to Contractor negligence shall be immediately restored at the Contractor's expense. Restoration of other damaged areas will be measured and paid for under the appropriate bid item. Temporary control measures may be removed upon completion of the project, as determined by the Water Quality Partial Acceptance walk-through. If removed, the area in which these control measures were constructed shall be returned to a condition similar to that which existed prior to its disturbance. Removed control measures shall become the property of the Contractor. If the Contractor fails to complete construction within the approved contract time, the Contractor shall continue erosion and sediment control operations at its expense until acceptance of the Work. Sediment removed during maintenance of control measures and material from street sweeping may be used in or on embankment, provided it meets the requirements of Section 203 and is distributed evenly across the embankment.

Additional aggregate may be required for maintenance but will not be measured and paid for separately. The use of prefabricated VTPs is highly encouraged. Prior to delivery to the site, the Contractor shall provide a submittal to the Engineer for review and approval. The prefabricated VTP shall not be installed until written acceptance is provided by the Engineer. Detention Pond. Permanent detention ponds shown on the plans may be used as temporary control measures if the following conditions are met: 1. The pond is designated as a construction control measure in the SWMP. 2. The pond outfall and outlet are designed and implemented for use as a control measure during construction in accordance with good engineering, hydrologic, and pollution control practices. The stormwater discharges from the outfall shall not cause degradation or pollution of State waters and shall have control measures as appropriate. 3 All silt shall be removed, and the pond returned to the design grade and contour prior to project acceptance. (r) Aggregate Bag. Aggregate bags shall be placed on a stable surface, consisting of hardscape or compacted gravel. If approved by the Engineer, the aggregate bag may be placed on compacted dirt areas, where bags conform to the surface and can effectively minimize sediment transport. Aggregate bags shall not be placed in concentrated flow areas. Aggregate bags shall be installed to conform to the surface without gaps to ensure that discharge water does not cause erosion. The Contractor shall remove all accumulated 174 October 4, 2023 29 REVISION OF SECTION 208 EROSION CONTROL sediment and debris when the sediment accumulation reaches 1/2 the height of the bag. If the bag fails or is damaged, it shall be immediately repaired or replaced at the Contractor's expense. ( s ) Surface roughening. Surface roughening creates horizontal grooves along the contour of the slope. Roughening may be accomplished by furrowing, scarifying, ripping, or disking the soil surface to create a 2 to 4 -inch minimum variation in soil surface. (t) Vertical Tracking. Vertical tracking involves driving a tracked vehicle up and down the soil surface and creating horizontal grooves and ridges along the contour of the slope. Sandy soils or soils that are primarily rock need not be tracked. (u) Temporary Stream Crossing. Temporary stream crossings shall be completed by the Contractor in close coordination with the appropriate regulatory agencies. Temporary stream crossings shall be constructed in such a manner as to prevent impacting water quality and flows in the drainageway. A design for the temporary stream crossing has been provided in the plans. The Contractor shall be responsible for verifying the design using a Professional Engineer retained by the Contractor. If the Contractor's engineer requests any changes, they shall be responsible for providing a professional engineering analysis and design to show the details required to achieve the requirements for the crossing. The Contractor's Engineer shall stamp, date, and sign the revised typical detail. A separate professional analysis shall be completed for each temporary stream crossing. If the Contractor or Contractor's engineer wishes to change the temporary stream crossing, it shall be designed to be overtopped by high flows, debris laden flows, or ice laden flows. The Contractor's engineer shall provide a design for the crossing that meets the following criteria: 1. The crossing shall pass the peak flow from a 2 -year frequency, 24 -hour duration storm event. 2. The design shall include a designated overflow route for storm events greater than the 2 -year frequency, 24 -hour duration storm event and provide a protected overflow path. 3 In cases where channel banks are overtopped by this design storm event, the crossing structure shall be designed and constructed such that it will not cause erosion or damage due to increases in water surface profiles to adjacent properties. 4 The design capacity of the crossing structure shall not create a damaging or potentially damaging increase in flood heights (<0.10 feet) or velocities over existing conditions. 5 The design shall not create a threat to public health, safety and welfare or impair the natural hydrologic functions of the floodplain or channel. 6 Approach grades to the temporary crossing shall be less than 10%. The width of the crossing shall be sized to the vehicles using the crossing and to prevent spillage directly into the stream. 7 Temporary stream crossings represent channel constrictions in most cases and thus they shall be in service for the shortest practical period of time and shall be removed as soon as their purpose is complete to avoid the potential to cause or exacerbate flooding. 8 Locations for temporary stream crossings shall be selected where erosion potential is low by evaluating channel geometry, slopes and side slope material. The stream channel conditions, overflow areas, and surface runoff control at the site shall be evaluated before choosing the location and type of crossing. 175 October 4, 2023 30 REVISION OF SECTION 208 EROSION CONTROL 9 The Contractor's engineer shall ensure the velocity at design flow at the outlet of the crossing structure is nonerosive for the receiving stream channel. In order to ensure nonerosive velocities, the Contractor's Engineer shall carefully evaluate the placement of the crossing, the size of the downstream opening in the crossing, and flow velocities under all conditions. 10. Aggregate used for the roadway approach and crossing shall be properly sized based on expected flows and velocities. A minimum layer of stone or recycled concrete that is 1/2 the diameter of the culvert pipe or 12 inches thick, whichever is greater shall be used. 11. The drainageway shall be crossed in a straight reach, rather than on a bend, if possible. Crossings shall be installed as close to perpendicular to the stream channel flow path as possible. The Contractor shall ensure that all necessary materials and equipment are on -site prior to any the start of any work. The construction shall be completed in an expedient manner so the crossing can be removed and then any disturbed areas stabilized immediately. The Contractor shall provide "Clean Equipment" certifications for all equipment that will be used on or around the temporary stream crossing. Equipment, materials, and/or vehicles shall not be stored on the crossing. Upon removal of the crossing, the portion of the side slope that is above the observed water elevation shall be stabilized as specified in the plans prior to accepting flows. The substrate and toe of slope that has been disturbed due to construction activities shall be restored to proposed or preconstruction conditions and fully stabilized prior to accepting flows. The area of ground disturbance shall be limited and appropriate soil erosion and sediment control measures shall be implemented. Alteration to the stream banks and bed shall be kept to the minimum necessary for an effective and safe crossing. Fish passage shall be evaluated when crossing a stream with aquatic life, which may require an assessment of what is present in the stream. Timing of crossing activities shall avoid impacting fish spawning runs. Impacts to mussel beds and endangered or threatened species shall be avoided. The temporary stream crossings shall be inspected after runoff -producing precipitation events to check for blockage in channel, erosion of abutments, channel scour, riprap displacement, or piping. Repairs shall be made immediately to prevent further damage to the structure. Temporary stream crossings shall be immediately removed when they are no longer needed. The channel shall be restored to its original cross- section, smoothed, and all disturbed areas shall be stabilized. Turbidity Curtain. Set all curtain anchor points (including anchor buoys). Care must be taken to ensure that anchor points are of sufficient holding power to retain the curtain under the existing current conditions, prior to putting the furled curtain into the water. Anchor buoys should be employed on all anchors to prevent the current from submerging the flotation at the anchor points. After the anchors have been secured, the furled curtain should be secured to the upstream anchor point and then sequentially attached to each next downstream anchor point until the entire curtain is in position. Before unfurling, the "lay" of the curtain should be assessed and any necessary adjustments made to the anchors. Once the location has been deemed adequate, the furling lines may be cut to allow the skirt to drop. Anchor lines shall be attached to the flotation device, not to the bottom of the curtain. The anchoring line attached to the flotation device on the downstream side will provide support for the curtain. Attaching the anchors to the bottom of the curtain could cause premature failure of the curtain due to the stresses imparted on the middle section of the curtain. October 4, 2023 31 REVISION OF SECTION 208 EROSION CONTROL The Contractor shall maintain the turbidity curtain to ensure its continuous protection of the watercourse. The curtain shall be inspected daily. Any visible plume of cloudy water passing beyond the curtain from the construction area shall constitute inadequate performance of the turbidity curtain. The Contractor shall immediately modify, adjust, or repair any portion of the turbidity curtain to correct inadequate performance. The turbidity curtain shall remain in place until the protected construction activities are complete and the turbidity of the water enclosed is reduced to acceptable levels. The turbidity curtain shall be removed in such a way as to minimize release of sediment. Sediment behind the curtain shall be removed before removal of the curtain, if directed by the Engineer. Any resulting turbidity shall be allowed to settle before removal proceeds. The site selected to bring the curtain ashore shall be free of sharp objects such as rocks, construction materials, cement, etc. in order to minimize the risk of damage when pulling the curtain out of the water. 208.06 Materials Handling and Spill Prevention. The SWMP Administrator shall clearly describe and record on the SWMP, all practices implemented at the site to minimize impacts from procedures or significant material that could contribute pollutants to runoff. Areas or procedures where potential spills can occur shall have a Spill Response Plan in place as specified in subsections 107.25(b) or 208.06(c). Construction equipment, fuels, lubricants, and other petroleum distillates shall not be stored or stockpiled within 50 horizontal feet of any State waters or more if the Contractor determines necessary. Equipment fueling and servicing shall occur only within approved designated areas. (a) Bulk Storage Structures. Bulk storage structures for petroleum products and other chemicals shall have impervious secondary containment or equivalent adequate protection so as to contain all spills and prevent any spilled material from entering State waters. Secondary containment shall be capable of containing the combined volume of all the storage containers plus at least 10 percent freeboard. For secondary containment that is used and may result in accumulation of stormwater within the containment, a plan shall be implemented to properly manage and dispose of all accumulated stormwater which is deemed to be contaminated (e.g., has an unusual odor or sheen). (b) Lubricant Leaks. The Contractor shall inspect equipment, vehicles, and repair areas daily to ensure petroleum, oils, and lubricants (POL) are not leaking onto the soil or pavement. Absorbent material or containers approved by the Engineer shall be used to prevent leaking POL from reaching the soil or pavement. The Contractor shall have onsite approved absorbent material or containers of sufficient capacity to contain any POL leak that can reasonably be foreseen. The Contractor shall inform all Spill Response Coordinators in accordance with the Spill Response Plan if unforeseen leakage is encountered. All materials resulting from POL leakage control and cleanup shall become the property of the Contractor and shall be removed from the site. Control, cleanup, and removal of by-products resulting from POL leaks shall be performed at the Contractor's expense. ( c ) Spill Response Plan. A Spill Response Plan shall be developed and implemented to establish operating procedures for handling potential pollutants and preventing spills. The Response Plan shall contain the following information: 1. Identification and contact information of each Spill Response Coordinator. 2. Locations of areas on the project site where equipment fueling, and servicing operations are permitted. 3 Location of clean-up kits. 4 Quantities of chemicals and locations stored on -site. Secondary containment is required for bulk storage over 55 gallons. 177 October 4, 2023 32 REVISION OF SECTION 208 EROSION CONTROL 5 Label system for chemicals and Safety Data Sheets (SDS) for products. 6 Clean-up procedures to be implemented in the event of a spill that does not enter State waters or ground water. 7 Procedures for spills of any size that enter surface waters or groundwater or have the potential to do so. CDOT's Erosion Control and Stormwater Quality Guide contains spill notification contacts and phone numbers required in the Spill Response Plan. 8. A summary of the employee training provided. Information in items (1) through (8) shall be updated in the SWMP when they change. 208.07 Stockpile Management. Material stockpiles shall be located 50 horizontal feet away from State waters and shall be confined so that no potential pollutants will enter State waters and other sensitive areas as defined in the Contract. Locations shall be approved by the Engineer. Erodible stockpiles (including topsoil) shall be contained with acceptable control measures at the toe (or within 20 feet of the toe) throughout construction. Control measures shall be approved by the Engineer. The SWMP Administrator shall describe, detail, and record the sediment control devices on the SWMP. 208.08 Limits of Disturbance. The Contractor shall limit construction activities to those areas within the limits of disturbance (LDA) shown on the plans and cross -sections. Construction activities, in addition to the Contract work, shall include the on -site parking of vehicles or equipment, on -site staging, on -site batch plants, haul roads or work access, and all other activities which would disturb existing soil conditions. Staging areas within the LDA shall be as approved by the Engineer. Construction activities beyond the limits of disturbance due to Contractor negligence shall be restored to the original condition by the Contractor at the Contractor's expense. The SWMP Administrator shall tabulate additional disturbances not identified in the CDPS-SCP application and indicate changes to locations and quantities on the SWMP. The Contractor shall report the changes and additional disturbances to the Engineer, Water Quality Control Division of CDPHE, and all other involved agencies. The Contractor shall pursue stabilization of all disturbances to completion. 208.09 Regulatory Mechanism for Water Quality. Per Part I.B.1.c. of the CDPS-SCP, the permittee shall assess the adequacy of control measures at the site and the need for changes to those control measures to ensure continued effective performance. The Contractor shall comply with the Water Quality Specifications as specified in Subsection 208.09(a)(7) and the CDPS-SCP. Failure to comply with the requirements of this section may result in liquidated damages as outlined below from the County and/or monetary penalties from CDPHE for which the Contractor is responsible. The following procedures shall be implemented to ensure the Contractor is meeting the CDPS-SCP, Section 107.25, and Section 208 requirements. Findings not in compliance with Water Quality Specifications, as detailed in subsection 208.09(a)(7), shall be documented by the SWMP Administrator or ECI on Form 1176 during weekly and post -storm water quality control inspections, routine SWMP audits, or observation by the Engineer. The Engineer will immediately notify the Contractor of these findings by issuing a Form 105. Failure by the Contractor to clarify a finding location with the Engineer shall not interrupt the timelines noted in subsection 208.09(b). Timelines noted in subsection 208.09(b) do not indemnify the Contractor from failing to comply with CDPS-SCP timelines for corrective actions. Findings shall be corrected as soon as possible, immediately in most cases but no longer than 24 hours, to minimize the discharge of pollutants. (a) Definitions. 178 October 4, 2023 33 REVISION OF SECTION 208 EROSION CONTROL 12. Compliance Assistance. A low -risk event as determined by the Engineer.

Liquidated damages are for the Contractor's failure to comply with the Water Quality Specifications and/or the CDPS-SCP. 179 October 4, 2023 34 REVISION OF SECTION 208 EROSION CONTROL Liquidated damages will accumulate for each finding, for each cumulative day that the finding remains uncorrected. 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 in accordance with 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. 1. Regular Finding. The time required to repair a Regular Finding shall begin at the conclusion of the SWMP inspection. The correction of a Regular Finding shall begin as soon as possible, immediately in most cases but not more than 24 hours from the time of the finding. The Engineer shall issue a Form 105 informing the Contractor of the finding and the need for correction to occur. If a finding cannot be immediately corrected, the Contractor shall request a deferment per Section 208.09(c). The Engineer will issue a Form 105 notifying the Contractor that Liquidated Damages are accruing at $1,500 per day per finding for each full or partial calendar day a Regular Finding remains uncorrected after 24 hours from discovery. Each uncorrected or undeferred Regular Finding will be assessed as recalcitrant and the Engineer will issue a project -wide stop work order if the Regular Finding is not addressed within 48 hours after the SWMP inspection has concluded. The Contractor shall fix each recalcitrant finding and submit a plan to avoid future instances of each recalcitrance to the Engineer for approval. The recalcitrance plan shall be in writing, signed by the Contractor and shall include: A. A description of each Recalcitrant Finding. B. Why the corrective action for each Recalcitrant Finding was not implemented within 2 days. C. How the Contractor will avoid future recalcitrance. The Engineer will discuss the recalcitrance plan and may meet with the Superintendent to recommend modifications, if needed. The Engineer will issue a Form 105 accepting or rejecting the recalcitrance plan within 24 hours of the Contractor submitting a plan or resubmitting a modified plan. The Contractor will neither be reimbursed for costs incurred to fix each Recalcitrant Finding pertaining to a control measure in the SWMP plan nor costs to prepare the recalcitrance plan. The Contractor shall propose additional control measures, if needed, according to subsection 208.04(a). The project -wide Stop Work Order and Liquidated Damages will be assessed until approval of the corrective action for each Recalcitrant Finding and approval of the Contractor's recalcitrance plan by the Engineer is given. After written approval by the Engineer, the project - wide Stop Work Order will be lifted, and accrual of Liquidated Damages will cease once the corrective work has been completed. If the Contractor fails to perform corrective work by the second day from discovery, the County shall have the option of utilizing a third -party to complete the corrective work. The Contractor shall be responsible for reimbursing the County the cost of utilizing a third -party to complete the October 4, 2023 35 REVISION OF SECTION 208 EROSION CONTROL 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.

(b) General Dewatering Requirements. 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 shall 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. (c) Structure Dewatering Construction Requirements: 190 October 4, 2023 3 REVISION OF SECTION 211 DEWATERING AND DIVERSIONS The Contractor shall obtain a construction dewatering permit and water quality shall conform to subsection 107.25(b)(7) &(8) of the Specifications prior to the start of the dewatering process.

The Contractor shall remove all groundwater, seepage, stormwater and other water that accumulates in the excavation during construction. All structure excavations shall be kept free of water during construction or until otherwise requested by the Contractor and approved by the Engineer. The Contractor shall prevent the softening of the bottom of excavations and the formation of "quick" conditions or "boils" during excavation. The occurrence of such conditions will require over -excavation and subsequent backfilling of soils meeting the requirements of the CDOT Specifications at no additional cost to the Owner. Additional costs for trench bottom stabilization resulting from inadequate dewatering and non-compliance with the specifications included herein, as determined by the Engineer, shall not be measured and paid for separately but shall be included in the Work. October 4, 2023 4 REVISION OF SECTION 211 DEWATERING AND DIVERSIONS The Contractor shall compact native soil at the bottom of the excavation prior to placing bedding in accordance with the specifications. 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. Prior to advancing the structure excavation below the pre -construction groundwater level, the Contractor shall excavate a test pit or install another form of groundwater measurement. Water levels in the test pit shall be measured and recorded and the information provided to the Engineer. Measured water levels shall show that the groundwater has been lowered to the minimum level stated herein.

Flows from existing storm drain pipelines; and 192 October 4, 2023 5 REVISION OF SECTION 211 DEWATERING AND DIVERSIONS 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 in accordance with Subsection 105.02. The diversion plan shall include the following: 1.

This includes, but is not limited to roadway earthwork, bridge demolition or construction, new signing, new lighting, new guardrail posts, erosion control, and minor drainage. The removal of nests without fledglings before construction shall be coordinated with the Engineer. MATERIALS AND CONSTRUCTION REQUIREMENTS 240.02 The Contractor shall schedule clearing and grubbing operations and work on structures to avoid taking (pursue, hunt, take, capture or kill; attempt to take, capture, kill or possess) migratory birds protected by the Migratory Bird Treaty Act (MBTA). Weld County will retain a qualified wildlife biologist for this project. The Contractor shall coordinate with the Engineer and Weld County's wildlife biologist during the course of the project. (a) Vegetation Removal. When possible, vegetation shall be cleared by the Contractor prior to the time when active nests are present. Vegetation removal activities shall be timed to avoid the migratory bird breeding season which begins on April 1 and runs to August 31. All areas scheduled for clearing and grubbing between April 1 and August 31 will be surveyed within the work limits by Weld County's biologist for active migratory bird nests. Weld County's biologist will also survey for active migratory bird nests within 50 feet outside work limits. Contractor personnel shall enter areas outside the right of way only if a written, signed document granting permission to enter the property has been obtained from the property owner. The Contractor shall document all denials of permission to enter property. The Contractor shall avoid all active migratory bird nests. The Contractor shall avoid the area within 50 feet of the active nests or the area within the distance recommended by the biologist until all nests within that area have become inactive. Inactive nest removal and other necessary measures shall be incorporated into the Work as follows: (1) Tree and Shrub Removal or Trimming. Tree and shrub removal or trimming shall occur before April 1 or after August 31 if possible. If tree and shrub removal or trimming will occur between April 1 and August 31, a survey for active nests shall be conducted by the Weld County's biologist within the seven days immediately prior to the beginning of work in each area of tree and shrub removal or trimming. The Contractor shall notify the Engineer at least 10 working days in advance of the need for the County's biologist to perform the survey. The survey shall be conducted for each phase of tree and shrub removal or trimming. If an active nest containing eggs or young birds is found, the tree or shrub containing the active nest shall remain undisturbed and protected until the nest becomes inactive. The nest shall be protected by placing fence (plastic) a minimum distance of 50 feet from each nest to be undisturbed. This buffer dimension may be changed if determined appropriate by the County's biologist and approved by the Engineer. Work shall not proceed within the fenced buffer area until the young have fledged or the nests have become inactive. If the fence is knocked down or destroyed by the Contractor, the Engineer will suspend the Work, wholly or in part, until the fence is satisfactorily repaired at the Contractor's expense. Time lost due to 220 October 4, 2023 2 SECTION 240 PROTECTION OF MIGRATORY BIRDS BIOLOGICAL WORK PERFORMED BY THE CONTRACTOR'S BIOLOGIST such suspension will not be considered a basis for adjustment of time charges but will be charged as contract time. The County's biologist will conduct raptor nest surveys within 0.5 mile of the construction site before the start of construction and before each construction phase. This survey can be done with binoculars. If construction activities are located within the Colorado Division of Wildlife (CDOW) recommended buffer zone for specific raptors, "NO WORK" zones shall be established around active sites during construction according to the CDOW standards or as recommended by the wildlife biologist in consultation with the CDOW. The "NO WORK" zone shall be marked with either fencing or signing. Work shall not proceed within a "NO WORK" zone until the County's biologist has determined that the young have fledged, or the nest is unoccupied. (2) Grasses and Other Vegetation Management. Due to the potential for encountering ground nesting birds' habitat, if work occurs between April 1 and August 31, the area shall be surveyed by the County's biologist within the seven days immediately prior to ground disturbing activities. The Contractor shall notify the Engineer at least ten working days in advance of the need for the County's biologist to perform the survey.

END OF SECTION 237 October 4, 2023 1 REVISION OF SECTIONS 420 AND 712 G EOSYN TH ETI CS Section 420 of the Standard Specifications is hereby revised for this project as follows: S ubsection 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. S ubsection 420.06, paragraph 1 shall be deleted and replaced with the following: 420.06 Erosion Control and Drainage. Geotextiles for erosion control or drainage shall be loosely laid (not stretched) with the roll direction the same as the anticipated water flow, and in a manner that avoids any rupture of the cloth. Geotextiles used for erosion control or drainage shall meet the requirements of subsection 712.08 and Table 712-2a. Geotextile (Drainage)(Class 1) shall be placed under all riprap as shown on the plans or as directed by the Engineer. S ubsection 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 geotextile shall be placed by machinery or by hand labor. The geotextile shall not be dragged across the subgrade. The geotextile shall be unrolled in the direction of travel so the machine direction (i.e., long axis) of the roll is parallel with channelized traffic patterns. The geotextile shall be rolled out flat and tight with no folds or wrinkles. Wrinkles and folds in the geotextile (not associated with roadway curves) shall be removed by stretching and staking as required. The geotextile may be held in place before the placement of the aggregate base course or other cover material by pins, staples, or piles of fill or rock. On curves, the geotextile may be folded to conform to the curve or by cutting the roll to match the curve . 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 R Strength -Value Overlap Width Seam (Inches) of Unsewn 5-10 30 10-20 24 > 20 18 238 October 4, 2023 2 REVISION OF SECTIONS 420 AND 712 G EOSYN TH ETI CS If 30 inches of overlap is required, the overlap shall be sewn or otherwise adhered to limit the potential formation of a slip plane between the overlapped panels. Sewn seams shall be per the manufacturer's recommendations. Overlap the geotextile in the direction that fill will be spread to avoid peeling -back of the geotextile at overlaps by the advancing fill. Cut and overlap the geotextile to accommodate curves. The geotextile shall be cut using sharp shears, razor knives or handheld power (i.e., "cutoff") saws. The geotextile shall be cut to conform to immovable protrusions, such as manhole covers and vertical utilities. Overlap lengths will not be paid for separately but will be considered subsidiary to item 420. (c) Fill Placement: Before covering the geotextile separator with fill materials, the condition of the geotextile shall be inspected by the Engineer to determine that no holes, rips or other defects exist. If any defects are observed, the section of the geotextile containing the defect shall be repaired by placing a new layer of geotextile extending beyond the defect in all directions a minimum distance equal to the overlap shown in Table 420-1. Alternatively, the defective section may be replaced. See subsection 420.07(e). The first lift of cover material shall be end -dumped or spread over the geotextile from the edges of the geotextile. The height of the dumped pile shall be limited to avoid local bearing capacity failures. The first lift of cover material shall be graded to a 12 -inch thickness or to top of grade whichever is less and compacted. Equipment shall not be on the treated area with less than the minimum thickness of compacted cover material over the geotextile. Small dozer equipment or front-end loader shall be used to spread the cover material. Construction vehicles shall be limited in size and weight such that rutting in the initial lift is no deeper than 3 inches. If rut depths exceed 3 inches, the Contractor shall use a smaller size and weight of construction vehicles. Ruts shall be filled in with cover material. Construction equipment shall not travel over the exposed geotextile at speeds of more than 5 mph. Construction equipment shall not make turns on the first lift of cover material. Construction vehicles can dump aggregate fill as they advance, provided the construction traffic does not cause significant rutting upon bare subgrade. Sudden braking, sudden starting and sharp turning shall be avoided. Tracked construction equipment shall not be operated directly upon the exposed geotextile. 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. 239 October 4, 2023 3 REVISION OF SECTIONS 420 AND 712 G EOSYN TH ETI CS Subsection 420.10 shall be revised to include the following: Payment will be made under: Pay Item Pay Unit Geotextile Separator Square Yard Geotextile (Drainage)(Class 1) will not be measured and paid for separately but shall be included in work for the riprap pay item.

The geogrid reinforcement shall be composed principally of polypropylene or high density polyethylene. 242 October 4, 2023 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 InterAx NX650 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. Smooth grade and compact the soils using appropriate compaction equipment. Grade or crown the surface for positive drainage away from the construction zone. ( c ) Geogrid Installation. Geogrid shall be laid at the proper elevation and alignment as shown on the plans or as directed by the Engineer. Geogrid shall be oriented such that the roll length runs parallel 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. 243 October 4, 2023 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.

END OF SECTION 282 October 4, 2023 1 REVISION OF SECTION 632 NIGHT WORK LIGHTING Section 632 is hereby added to the Standard Specifications for this project as follows: DESCRIPTION 632.01. This work consists of furnishing, installing, operating, maintaining, moving, adjusting, and removing lighting to illuminate construction work spaces for night work. Night work will be defined as work performed between 30 minutes before sunset and 30 minutes after sunrise. MATERIALS AND EQUIPMENT 632.02. The Contractor shall provide lighting for night work in the activity area work space where construction equipment, workers on foot, or both are present. The work space is that portion of the roadway closed to road users, or outside of the roadway, set aside for workers, equipment and materials performing contract work. The work space may be stationary or may move as the work progresses. Illumination may be accomplished by using a combination of portable lights, floodlights, equipment mounted lights, or other lighting methods that will provide the required minimum lighting intensity. Light fixtures that are mounted on the construction equipment shall have a secure connection to minimize vibration and ensure that the view of the equipment operator is not obstructed. Portable lights shall be aimed either generally parallel or perpendicular to the roadway, aimed downward towards the work to avoid glare to oncoming drivers. Existing street and highway lighting shall not eliminate the need for the Contractor to provide work area lighting. Vehicle headlights shall not be permitted as the sole means of illumination while working. 632.03 Portable Generator and Inverter Generator. The Contractor shall provide a portable generator, inverter generator, or both as needed to power the added equipment mounted lights on motorized equipment if the existing power supply on the equipment is insufficient to power the added lights. Fuel tank capacity and availability of fuel on site shall be sufficient to permit uninterrupted operation throughout the planned shift. All power sources shall be equipped with a ground -fault circuit interrupter. The generator shall be placed or temporarily mounted on the equipment without obstructing access onto the equipment or the view of the operator. 632.04 Light Meter. The Contractor shall furnish a light meter for use by the Engineer. The meter shall have a digital display calibrated to NIST standards, shall be cosine and color corrected with an accuracy of +/- 5 percent. The light meter shall remain the property of the Contractor after final acceptance. CONSTRUCTION REQUIREMENTS 632.05. Lighting for night work shall include: (1) Minimum lighting intensity of 5 -foot candles for work space illumination. (2) Illuminate the stationary work space as stated in (1) above where construction equipment, workers on foot or both are present. (3) Light sources shall be positioned not to interfere with or impede traffic in any direction and not cause glare for motorists or onto adjacent properties whenever possible. The Contractor shall make adjustments, use visors or shields, or both to minimize glare. (4) Illumination for mobile operations within a closed travel lane with traffic control devices will be defined as 20 feet in front of and behind and 5 feet to each side of each piece of moving equipment. (5) The Contractor shall provide portable lights for Engineer's and contractor personnel performing materials testing for either mobile or stationary operations to illuminate the testing work space as stated in (1) above. 283 October 4, 2023 2 REVISION OF SECTION 632 NIGHT WORK LIGHTING For concrete operations at night, the Contractor shall illuminate the designated concrete truck washout location including the access and the wash out site. (6) Workers on foot, performing work within a moving work space (i.e., striping layout/installation, surveying, etc.) shall wear ANSI approved high visibility apparel and headwear for Class 3 risk exposure including vest, Class E pants or leg gaiters, and reflective tape on hard hats. Workers may use portable lighting that can be worn on the hard hats that provide 360 -degree visibility. (7) Portable light towers and lights mounted on stands shall be sturdy and free-standing without the aid of guy wires or bracing. Minimum illumination levels as stated in (1) above shall be maintained at a distance of 5 feet on all sides of stationary equipment with either equipment mounted or free-standing lights. (8) The Contractor shall ensure that all pieces of equipment have operating lights to illuminate operator's controls, backhoe and loader buckets, and illuminate the equipment reach limits around rotating equipment (i.e., the paving machine shall have illumination for the hopper, auger, and screed areas). (9) The TCS vehicle shall have the rear of the truck illuminated while installing, maintaining, and removing traffic control devices unless sufficient lighting levels exist with stationary lights. (10) The Contractor shall maintain a uniformity ratio no greater than 5:1 over the stationary work space. Uniformity ratio is the ratio of average to minimum horizontal illuminance within the work space. The uniformity ratio shall be determined by dividing the average of all light meter measurements by the light meter measurement at the darkest spot within the illuminated area. 632.06 Night Work Lighting Plan. The Contractor shall submit a lighting plan to the Engineer for review signed by the Contractor's designated person three days in advance of the Preconstruction Conference. The lighting plan shall appropriately describe the work and include the following: (1) Layout drawing and supplemental narrative showing light locations, equipment mounted lights, and configuration including both typical spacing and lateral placement for each work activity. (2) Tabulation of lights for those lights that are included within the Night Work Lighting pay item. Lights included in the tabulation such as tower lights, lights mounted on stands and lighting mounted to mobile equipment (not original equipment lights) but those additional equipment mounted lights or portable lights that provide the 20 feet in front and behind illumination zone shall have catalog cuts giving the specific brand names, model numbers, lamp type and wattage. (3) Narrative description of those operations where workers will be on foot in a moving work space. (4) Details of hoods, visors, louvers, shields or other means to be used to minimize glare. The plan shall be revised and updated by the Contractor as requested by the Engineer during the progress of the work to accommodate changes to the work. 632.07 Inspection of Lighting. Lighting inspection by the Engineer will be performed jointly with the Contractor's designated person on a drive through the project to include (1) observation of the lighting setup to evaluate glare potential for drivers and workers and (2) light meter measurements to determine minimum illumination levels. The Contractor shall make adjustments to the lighting as needed based on the Engineer's inspection. In the event of any failure of the lighting system, the Engineer may determine to discontinue work until the required level of illumination is restored. Delays due to insufficient lighting levels are the responsibility of the Contractor. Any corrections and deficiencies needed to provide the minimum illumination levels shall be addressed by the start of the next work shift. 284 October 4, 2023 3 REVISION OF SECTION 632 NIGHT WORK LIGHTING The Engineer will take light meter measurements to verify the minimum lighting levels using a light meter provided by the Contractor during the night work shift. Light meter readings will be taken within the work space where work is being performed, in a horizontal plane, light sensor part of the meter held parallel to the ground with the sensor aimed upward, 3 feet above the pavement or ground surface. Meter readings will be taken at the source at 5 -foot intervals out to the illuminated work space perimeter. These measurements will be documented and filed in the project records. 632.08 Lighting for Flagger Stations. For nighttime flagging, flagger stations shall be illuminated by an overhead light source providing a minimum lighting intensity level of 5 -foot candles measured 1 foot out from the flagger's chest. The flagger station light shall illuminate the station area with a radius of at least the width of the lane plus 5 feet, and be centered on the flagger in the initial flagging position. The size of the illuminated area shall be increased to account for flagger movements required to control traffic. The flagger station lighting shall be maintained at an adequate height above the pavement and be capable of being shielded through the use of visors, hoods, louvers, or screens as needed to minimize glare to approaching traffic and spilling over onto adjacent properties. METHOD OF MEASUREMENT 632.09. Lighting for night work will not be measured but will be paid for as a single lump sum. BASIS OF PAYMENT 632.10. Payment for lighting as shown on the Night Work Lighting Plan will include all labor, materials, and equipment necessary to complete and maintain the Work. Payment for lighting will include portable 360° visibility lighting worn on hard hats. Progress payments will be made based on the lump sum price bid as follows: 20 percent when the Lighting for Night Work Plan has been submitted, accepted, and satisfactory lighting of nighttime operations has begun; the remaining 80 percent will be paid in equal monthly progress payments for the remaining time lighting is required for the night work operations. Payment will be made under: Pay Item Pay Unit Night Work Lighting Lump Sum Flagger station lighting, designated person, light meters, and additional power sources (generator and inverter) will not be measured and paid for separately but shall be included in the Work.

END OF SECTION 290 October 19, 2023 Bid Request No. B2300185, BR54/13A Bridge Replacement Project Weld County, Colorado ADDENDUM NUMBER ONE The following shall be incorporated into the CONTRACT DOCUMENTS, for the above -referenced PROJECT: Contractor Questions and Responses Mandatory Pre -Proposal Meeting Minutes Pre -Bid Meeting Attendance List Revision to Section 203 of the Specifications Revision to Section 401 of the Specifications Updated Bid Tabulation Receipt of Addenda Vicinity map for the East Davis Storage Facility 2023 BR54/13A Bridge Inspection Report Updated Plan Sheets 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. CONTRACTOR QUESTIONS AND RESPONSES Question 1: The bid documents identify July 15, 2024 as the completion date but the Notice to Bidders and the Pre -Bid Meeting Agenda shows August 30, 2024 as the completion date. What is the completion date? Answer 1: The anticipated completion date is on or before August 30, 2024. Question 2: Has the Purchasing Department moved? Answer 2: Yes, the Purchasing Department has relocated to 1301 N 17th Ave, Greeley, CO, 80631. References on pages 3 and 4 of the RFQ/RFP document shall be updated to reflect the new address. Question 3: There appear to be a few discrepancies with the quantities shown with in the Bid Tabulation and the Summary of Approximate Quantities shown in the plans. Can you provide clarification on the quantities? Answer 3: An updated Bid Tabulation is included with this addendum. Question 4: Is it possible for potential bidders to meet with the County in one on one meetings? Answer 4: To avoid violating the County's purchasing policies, it is not possible to meet with companies one on one until the bidding process is over. Question 5: Will the County allow the use of Primavera P6 scheduling software for generating the required schedules? Answer 5: No, Weld County does not have a license for Primavera P6 software and cannot review the logic used to generate the schedules. Weld County has a license for Microsoft Project, therefore, the only scheduling software that will be allowed is Microsoft Project. Question 6: Which existing utility relocations will take place before the notice to proceed and which one after? Which relocations will be coordinated by the County & which relocations will be coordinated by the Contractor? Answer 6: It is anticipated that the existing utility relocations will be completed by the start of construction. However, if the utilities have not been relocated, the Contractor will become responsible for coordinating the rest of the relocations and/or removals. The County will provide assistance to help with the utility relocations. As of October 18, 2023, DCP has completed their removals and will not be installing any new lines until after the construction is complete. As of October 18, 2023, PVREA is in the process of boring their line under the river and under CR 54. Once the bores are complete, they will begin relocating their line to the new location. Once the line has been relocated on brought online, they will begin the removals of the overhead power lines. They expect their work to be complete by the end of December. Little Thompson Water District is starting their bore of the river the week of October 23, 2023. Once the bore is complete, they will install their new line. Once the new line is installed and tested they will cut over to the new line and begin removals of the old line. They anticipate being complete with their work by the end of December. Xcel Gas has not provided a start date for their removals and relocation. Weld County continues to request their start date every week. CenturyLink has not provided a start date for their removals and relocation. Weld County continues to request their start date every week. Question 7: Does the Equipment list to be provided in item 3(d)(4) have to be a comprehensive list of the contractor's equipment or can it be just a list of equipment applicable to the job? Answer 7: The equipment list should be complete enough to show the contractor and their sub -contractors have enough equipment to perform the work required to complete the project. Question 8: Is an organizational chart and a staffing plan required to be part of the RFQ/RFP Response and if so, what section does it go in? Answer 8: If an organizational chart and a staffing plan will help convey how the contractor's team represents the best value to the County, it can be included in the Project Control section of your response. The organizational chart and staffing plan will be included in the 15 page limit. Question 9: The RFQ/RFP refers to project goals but they are not specifically identified in the bidding requirements. Does the County have any written goals for the project? Answer 9: Generally, the County expects the contractor and their team to identify the project goals which they think are important to the project and then explain how those goals will be met in the RFQ/RFP Response. At a minimum, Weld County expects the contractor to manage their staff and their subcontractors. The contractor will be expected to be proactive in their approach to solve issues that may arise on the project. Scheduling, process control testing, and effective erosion control activities are also items that are important to successfully completing the project. The County's goals would be to have a collaborative project where the contractor and the County work together to complete the project ahead of schedule and under budget. In order for this project to be successful, both parties have to be able to communicate timely and effectively with one another. Communication with the Weld County Engineer and Inspector will be critical to the success of the project. Question 10: Note 14 under the earthwork notes states that excavation required for the compaction of bases of cuts and fills shall be paid for under the reconditioning and compaction pay item. However, there is no reconditioning and compaction pay item. How will excavation required for the compaction of bases of cuts and fills be paid for? Answer 10: Note 14 was accidentally left in the plans. It should have been deleted. Excavation required for the compaction of bases of cuts and fills will be paid for the Embankment (CIP) pay item. A revised sheet removing the Note 14 in the earthwork notes will be issued. A revised sheet will be added to correct this note. Question 11: There appears to be several different requirements for embankment material. Note 16 of the Earthwork Notes requires the Class 6 ABC (Virgin) to have a minimum R -value of 69, the roadway prism under the Class 6 ABC shall have a minimum R -value of 30, and the HMA Pavement Section Detail shows material below Class 6 ABC as having a minimum R -value of 30. Section 203.03 of the specifications states the minimum R -value of the subgrade shall have an R -value of 40. Which R -value is to be used? Answer 11: The minimum R -value for Class 6 ABC (Virgin) shall be 69. Onsite embankment materials (materials located within the project area) can be used in the roadway prism as long as the contractor provides testing showing the onsite materials meet a minimum R -value of 30. The contractor shall be responsible for testing each separate area that is used for onsite embankment materials. Imported embankment material shall meet a minimum R -value of 40. A revision to section 203.03 will be issued. Question 12: The depth of the existing asphalt removal based on geotechnical borings varies from 5 to 8 inches of HMA. Payment for removal is based on square yardage measurement. The contractor shall be responsible for any additional cost of removal if the existing pavement and/or ABC section vary in depth. This conflicts with Note 9 that states, "In areas where existing pavement is removed, the subgrade shall be scarified to a depth of 8 inches, moisture conditioned to within 2 percent of optimum moisture content, and compacted to at least 95% of the maximum dry unit weight as determined as AASHTO T-99. A geosynthetic shall be place over the prepared subgrade as recommended in the project geotechnical report. Please verify. Is the geogrid listed as Geogrid (Tensar NX650) intended to be used as the geosynthetic? Answer 12: The County does not see a conflict with these two statements. All the asphalt shall be milled off and separated into 2 categories of recycled asphalt millings, clean millings and dirty millings. The clean millings will remain the property of the County and has to be hauled to our East Davis Storage Facility by the contractor. The dirty millings will become the property of the contractor and may be used as embankment fill within the project area. Refer to the Weld County Revision of Section 202.09. The removal of the asphalt mat will be paid for by the square yard regardless of whether the asphalt turns out to be 5 inches or 8 inches or something different. All the asphalt has to be milled off the roadway so the subgrade is exposed. The contractor is expected to determine their risk for performing this work and price the item accordingly. The layer that is left below the asphalt once it has been entirely milled off will be considered subgrade. The subgrade has to be scarified to a depth of 8 inches and then be conditioned and compacted as outlined in the specifications. Once the subgrade passes the compaction requirements, Geogrid (Tensar NX650) shall be placed on top of the subgrade and then the Class 6 ABC will be placed on top of the geogrid. Question 13: The Weld County Revision to Section 202.09 indicates a disposal area for asphalt millings. The address provided in the specification of 23782 CR 60.5 does not appear in internet searches. Can the address of the facility be verified? Answer 13: The address for the East Davis storage facility shown in the specifications is correct. From Highway 85, go east on East 8th St/WCR 60.5 approximately 4 miles. There is a sign on the east side of the access showing the Weld County East Davis address. The map below shows where the site is Question 14: Note 5 of the Earthwork Notes states the depth of topsoil removal shall be 12 inches. The Weld County Revision to Section 207.02(a) states onsite topsoil consists of the upper 6 inch layer of the A horizon. Answer 14: Weld County will approve a topsoil stripping depth of 6 inches. However, the contractor shall be aware that topsoil may be greater than 6 inches deep. If topsoil is discovered to be deeper than 6 inches, it shall be removed to a depth agreed to by the Engineer and the Contractor. Any excess topsoil left when the redistribution of the topsoil has been completed shall be removed from the project by the contractor at no to the County. The contractor will not be allowed to lose left over topsoil by fattening slopes or spreading it across the site due to federal and county floodplain regulations. A revised sheet will be issued to correct the note. Question 15: A 64 inch caisson is not a standard size. Is it acceptable to go to a 72 inch caisson? Answer 15: The design engineer has reviewed the caisson sizes and has changed the 64 inch caisson to a 66 inch caisson. If the contractor desires to use a 72 inch caisson, the contractor's professional engineer shall provide the new design for the caissons and provided stamped, signed, and dated drawings as well as the associated calculations for review and approval by Weld County. Question 16: Are there as -built drawings of the existing bridge? Answer 16: No, Weld County does not have the as -built drawings for the existing bridge. The latest bridge inspection report is included in this addendum. Question 17: The new bridge has to be out of the water by May 15, 2024. Does the temporary crossing have to be removed by that date? Answer 17: May 15, 2024 is the date that snowmelt runoff is expected to start. The temporary crossing does not have to be removed by May 15, 2024 but the contractor shall be aware that the temporary crossing is likely to be underwater and may be washed away by that date. If the temporary crossing has to be rebuilt, it will be done at no additional cost to Weld County. Question 18: The specification states the office trailers and lab trailer has to be located within 1/2 mile of the project. Does the County have any locations in mind for the office trailers and lab trailer? Answer 18: No, the contractor is responsible for finding locations for the trailers. The contractor is encouraged to talk to adjacent landowners to see if they are willing to allow the trailers to be setup on their property. Question 19: Is the laboratory trailer intended to be used only by the Process Control tester? Answer 19: No, the Owner Acceptance tester will also be using the laboratory trailer. Question 20: The summary of approximate quantities calls for Class 4 RCP. Does the Class 4 designation refer to the strength class or the sulfate resistance class? Answer 20: The Class 4 designation refers to the strength class of the RCP. Question 21: Class 4 RCP is a non-standard strength class that will have to be special ordered from the supplier. Is the use of Class 5 RCP acceptable to Weld County Answer 21: The County is willing to accept a strength class 5 for the RCP. Question 22: Is there an engineer's estimate available for the project? Answer 22: In order to avoid skewing the proposals, the engineer's estimate will not be made available until after a contractor has been selected. Question 23: On past projects the County has only allowed 20% RAP to be included in the asphalt mix designs. The project special provisions for this project say that 23% RAP is allowed to be included in the asphalt mix design. Can you verify which percentage of RAP will be allowed in the asphalt mix design? Answer 23: The asphalt mix designs for this project will be limited to 20% RAP. A new special provision has been included for Section 401 in this addendum.

S ubsection 203.4, paragraph 1 shall be deleted and replaced with the following: 203.04 General. The contractor shall ensure that all earthwork activities are performed with machine control to the accuracies specified below. The excavations and embankments shall be finished to smooth and uniform surfaces conforming to the typical sections specified. Variation from the subgrade plan elevations specified shall not be more than 0.08 foot. Where asphalt or concrete surfacing materials are to be placed directly on the subgrade, the subgrade plane shall not vary more than 0.04 foot. Materials shall not be wasted without written permission of the Engineer. Excavation operations shall be conducted so material outside of the slope limits will not be disturbed. Before beginning grading operations, all necessaryclearing and grubbing in that area shall have been performed per Section 201. Subsection 203.06, paragraph 1 shall be deleted and replaced with the following: 203.06 General Embankment Construction Requirements. Contractor Process Control is mandatory for this element. The Contractor's Process Control Representative shall be certified with Western Alliance for Quality Transportation Construction (WAQTC) Embankment and Base Testing and CDOT's Excavation, Embankment and Soil Inspection certification course. Only approved equipment and methods proposed by the Contractor in Method Statements (see Section 108.03(j)), shall be used in the placement of, moisture conditioning and compaction of, and/or reconditioning of cut/fill and embankment materials. The Contractor shall be responsible for determining the moisture conditioning, the type of equipment, and number of passes that are needed to achieve adequate compaction; however, compression type or vibratory rollers are required for granular materials, and sheepsfoot rollers are required for cohesive soils. Water trucks, haul trucks, and scrapers shall not be used as compaction equipment or as interim compactive measures, apart from shouldering materials. The Contractor shall use approved equipment or attachments for conditioning/mixing during embankment placement and/or cut/fill reconditioning, for soils classified as A-4 to A-7 to ensure consistent moisture conditioning without disturbing compaction of preceding lifts. Dozer shall not be allowed unless approved by Engineer. S ubsection 203.06, paragraph 4 shall be deleted and replaced with the following: The cleared surface shall be completely broken up by plowing or scarifying to a minimum depth of 8 inches or as specified in the Contract, the moisture content increased or decreased as necessary, and compacted to the specified embankment density for the material type present. S ubsection 203.07, paragraph 1 shall be deleted and replaced with the following: It is anticipated that the majority of the materials excavated on this project will be placed within the roadway prism or hauled off -site. However, the Project Engineer and Inspector have the authority to order certain material be placed within the embankment side slopes. Unsuitable excavation materials produced from muck excavation and pipe installation shall not be used for embankment and shall be hauled off the jobsite. Topsoil which has been stripped and stockpiled shall be placed on the top of embankment slopes. Materials incorporated into embankment fill shall be placed and compacted according to the following requirements: October 19, 2023 3 REVISION OF SECTION 203 EXCAVATION AND EMBANKMENT Subsection 203.07(a) shall be deleted and replaced with the following: (a) Soil Embankment. All soil embankment shall be placed in horizontal layers not to exceed 8 inches in loose lift thickness. Each layer shall be compacted before the placement of subsequent layers. Spreading equipment shall be used to obtain uniform thickness before compaction. As the compaction progresses, continuous mixing, leveling, and manipulating shall be done to assure uniform moisture and density. Additional work involved in drying soil embankment to the required moisture content shall be included in the contract price paid for excavating or furnishing the material with no additional compensation. When conduits (i.e., culverts, pipes, etc.) are installed in embankment material, the embankment shall first be constructed to a required height of a minimum of one foot above the top of conduit and for a distance on each side of the conduit of at least 5 times the diameter or span of the conduit, after which the trench shall be excavated and the conduit installed. Before trench excavation, the embankment material shall pass the compaction requirements for the Project. Soil embankment that is classified as A-1 material may be used to bridge across standing water or swampy ground within the embankment foundation and may be placed in lift thicknesses greater than 8 inches when used for this purpose if approved by the Engineer. A Sheepsfoot compactor shall not be used on A-1 material containing less than 30% retained on the %-inch sieve. Per the Western Alliance for Quality Transportation Construction (WAQTC) inspection guidelines, the appropriate equipment to use on granular soils such as an A-1 soil, a steel vibratory roller or pneumatic rubber - tired roller. Sheepsfoot rollers are appropriate for materials composed of cohesive soils and clay rich non -durable bedrock. Soil embankment with less than or equal to 30% retained on the 3/4 -inch sieve shall be tested for compaction using CP-80. Materials classified as AASHTO A-1, A-2-4, A-2-5, and A-3 soils shall be compacted at +/- 2 percent of optimum moisture content (OMC) and to at least 95 percent of maximum dry density determined per AASHTO T180, modified by CP-23. All other soil types are compacted to 95 percent of maximum dry density determined per AASHTO T99, modified by CP-23. Soils with 35 percent fines or less are compacted at +/- 2 percent of OMC. Soils with more than 35 percent fines are compacted at a moisture content equal to or above OMC to achieve stability of the compacted lift. Stability is defined as the absence of rutting or pumping as observed by the Contractor's Process Control representative and as approved by the Engineer. If the soils prove to be unstable when compacted at or above optimum moisture content, the moisture content required for compaction may be reduced below OMC as approved by the Engineer. Compaction shall be tested using nuclear density gauges (CP-80-13) at the frequencies specified in Table 106-1. Compaction tests shall be performed in accordance CP-80 and shall utilize 4 one - minute readings. The use of 1 fifteen -second test shall be not acceptable for Process Control testing. Field rock correction tests (CP-23-13) shall be performed at the frequencies specified in Table 106- 1 done for each compaction test performed. Rock corrections shall be performed per CP-23. The Process Control tester shall provide their own screen, scale, and hot plate or microwave. A field one -point moisture/density verification test (CP-25-13) shall be performed at the frequency specified in Table 106-1 to verify the use of the correct moisture/density curve. The test sites shall be selected randomly and shall be representative of the materials placed in the surrounding areas. The Contractor shall provide a stable platform on which the one -point tests can be performed. Any time a density verification test is over 100%, a field one point moisture/density verification test and a field rock correction test shall be performed to verify the use of the correct proctor. Before placing any soil embankment with greater than 30 percent retained on the 3/4 -inch sieve, the Contractor shall construct a test strip to the dimensions specified in the Contract or as directed by the Engineer. The test strip may be incorporated into the final embankment. The Contractor shall October 19, 2023 4 REVISION OF SECTION 203 EXCAVATION AND EMBANKMENT determine the moisture conditioning necessary to achieve compaction and shall determine the equipment and number of passes necessary to achieve adequate compaction. The Contractor shall use compression -type or vibratory rollers on granular materials and sheepsfoot rollers on cohesive soils. Adequate compaction shall be demonstrated by the absence of rutting, pumping, or deflection following a proof roll of the test strip using any piece of construction equipment that exerts a minimum 18 -kip per axle load. The proof roll will be observed and accepted by the Engineer. Once the test strip passes a proof roll, the Contractor may resume embankment construction using the same moisture conditioning and compaction methods that were used to construct the test strip. Placement, moisture conditioning, and compaction of every lift of soil embankment with greater than 30 percent retained on the 3/4 -inch sieve shall be observed by the Contractor's Process Control Representative and accepted by the Engineer. Adequate compaction of each lift shall be demonstrated as the absence of rutting, pumping, or deflection as construction equipment is routed over a lift following the compactive efforts that were used and accepted for the respective test strip. The Engineer may request a proof roll at any time to document the condition of a lift. Significant changes in the material being hauled for soil embankment with greater than 30 percent retained on the 3/4 -inch sieve will require construction of a new test strip, and demonstration of adequate compaction methods using a proof roll. Non -durable bedrock shall be watered to promote slaking and break down and pulverized or processed to a maximum particle size of 6 inches. These materials shall be placed and compacted as soil embankment except they shall be compacted with a heavy tamping foot roller weighing at least 30 tons. Each tamping foot shall protrude from the drum a minimum of 4 inches. Each embankment layer shall receive a minimum of four passes with the tamping foot roller. The roller shall be operated at a uniform speed not exceeding 3 miles per hour. No additional compensation will be made for additional roller passes to achieve specified density requirements. Non -durable Bedrock shall not be used to bridge over standing water or swampy ground within an embankment foundation. Non -durable bedrock shall also not be placed within 2 feet of the final subgrade elevation. Subsection 203.08 shall be revised to include the following: 203.08 Proof Rolling. Proof rolling with pneumatic tire equipment shall be performed using a minimum axle load of 18 kips per axle. A weigh ticket from an approved scale shall be furnished by the Contractor to substantiate this weight. Contractor's verified proof rolling equipment, meeting the 18 kip loading per axle, shall be available onsite during all phases of earthwork activities and as an erosion control method for dust control mitigation. A current certified scale ticket showing the fully loaded weight of the water truck(s) shall be submitted to the Engineer before any proof roll is performed for acceptance. The Engineer may require a proof roll at any elevation to verify stability. The subgrade shall be proof rolled after the required compaction has been obtained and the subgrade has been shaped to the required cross section. The proof roller shall be operated in a systematic manner so that a record may be readily kept of the area tested and the working time required for the testing. Areas that are observed to have soft spots in the subgrade, where deflection is not uniform or is excessive as determined by the Engineer, shall be ripped, scarified, dried or wetted as necessary, and recompacted to the requirements for density and moisture at the Contractor's expense. After replacement and re -compaction, these areas shall be proof rolled again and all failures again corrected at the Contractor's expense. The repair may involve muck excavation, geogrid reinforcement, replacement of excavated materials, or other methods as directed by the Engineer. October 19, 2023 5 REVISION OF SECTION 203 EXCAVATION AND EMBANKMENT After the subgrade has been stabilized, the Contractor shall perform proof rolling per subsection 203.08. Final proof rolling will take place a maximum of two days (48 hours) after all mechanical stabilization or unbound aggregate work has been completed, unless otherwise approved by the Engineer. Final proof rolling will take place a minimum of two days after all lime or other chemical stabilization work has been completed, unless otherwise approved by the Engineer. The finished surface shall be smooth and uniform conforming to the typical sections. Variation from the subgrade plan elevations shall not exceed 0.04 feet. All irregularities, depressions, or weak spots which develop shall be corrected at the Contractor's expense. The surface shall be maintained in a smooth condition, free from undulations and ruts until other work is placed thereon or the work is accepted. No separate payment will be made for areas of unsuitable material excavation, geogrid reinforcement, or replacement of excavated materials. Subsection 203.11(a) shall be revised to include the following: The disposal of unsuitable material and replacement of embankment will not be measured and paid for separately but shall be included in the Work. Geogrid and geotextile used in areas where unsuitable materials were removed and replaced with backfill material will not be measured and paid for separately but shall be incidental to the cost of the backfill material. Subsection 203.11(b) shall be deleted and replaced with the following: (b) Embankment. The quantities for Embankment (Complete in Place) and Unclassified Excavation (Complete in Place) will not be measured, but will be the quantity designated in the Contract, unless field changes are ordered. If field changes are ordered, the quantities will be calculated using the revised dimensions and the additional volume of material shall be approved in writing by the Engineer before beginning the Work. No allowances shall be made for shrinkage, swell, subsidence due to compaction of the existing ground or any other losses. The quantities for Embankment and Unclassified Excavation will not be measured, but will be the quantity designated in the Contract, unless field changes are ordered. If field changes are ordered, the quantities will be calculated using the revised dimensions and the additional volume of material shall be approved in writing by the Engineer before beginning the work. No allowances shall be made for shrinkage, swell, subsidence due to compaction of the existing ground or any other losses. Payment for Embankment and Unclassified Excavation shall be full compensation for all work necessary to complete the earthwork to the lines and grades when on the Plans.

END OF SECTION October 19, 2023 1 REVISION OF SECTION 401 PLANT MIX PAVEMENTS - GENERAL Section 401 of the Standard Specifications is hereby revised as follows: Subsection 401.02(a) shall be revised to include the following: (4) The job -mix formula for Pavement shall be established by a testing laboratory approved by the County and at the Contractor's expense. Copies of all test data shall be provided to and approved by the County prior to construction. Subsection 401.02(c) shall be added immediately following Subsection 401.02(b): (c) Reclaimed Asphalt Pavement (RAP) Mixes Furnished to the Project. RAP is allowed in hot mix asphalt (HMA) up to a maximum binder replacement of 20 percent for all lifts, provided all specifications for HMA are met. Fine Aggregate Angularity requirements shall apply only to the virgin fraction of the fine aggregate. The RAP shall not contain clay balls, vegetable matter, or other deleterious substances, and must meet the uniformity requirements as outlined below. HMA Project Verification Testing for asphalt content and gradation will be performed at the frequencies listed in the Field Materials Manual in accordance with CP-L 5120. The Contractor shall have an approved mix design for the amount of RAP to be used. The AC content of the RAP utilized in the Contractor RAP mix design shall be the average AC content determined in accordance with 1B or 1C, below, or alternatively, a minimum of five samples of the Contractors RAP stockpile may be sampled and the average AC content of the RAP be determined using AASHTO T- 164, Method A or B, or in accordance with 1C below. The Contractor shall determine the total binder replaced by the binder in the RAP pursuant to the following equation: Total Binder Replaced = (A x B) x 100/E Where: A = RAP % Binder Content * B= RAP %inMix * E = Total Effective Binder Content * * in decimal format (i.e., 2% is 0.02) The Total Binder Replaced by the binder in the RAP shall not exceed 20 percent of the effective binder content of either the mix design or the produced mix. The use of RAP shall be controlled in accordance with subsections 105.05 and 106.05. If the Contractor elects to use RAP, the following additional conditions shall apply: 1. The Contractor shall have an approved Process Control (PC) Plan that details how the RAP will be processed and controlled. The PC plan shall address the following: A. RAP Processing Techniques. This requires a schematic diagram and narrative that explains the processing (crushing, screening, and rejecting) and stockpile operation for this specific project. B. Control of RAP Asphalt Binder Content (AASHTO T-164, Method A or B). RAP Asphalt Binder Content may also be determined in accordance with CP-L 5120, provided a RAP AC content correction factor is determined through correlation testing with AASHTO T- 164, October 19, 2023 2 REVISION OF SECTION 401 PLANT MIX PAVEMENTS - GENERAL Method A or B. The correction factor shall be determined by performing correlation testing on the first five samples of the RAP AC content, then at a frequency of one for every five AC content tests thereafter. The correction factor shall be determined by calculating the average difference in AC content between CP-L 5120 and AASHTO T- 164, Method A or B, and applying the correction to the AC content determined in accordance with CP-L 5120. Frequency: 1/1000 tons of processed RAP material (minimum five tests) C. Alternative Control of RAP Binder Content. The Contractor may propose a RAP asphalt content correction factor to be used in conjunction with CP-L 5120. The proposed CP-L 5120 RAP asphalt content correction factor shall be used with all RAP asphalt contents tested for the mixture design and quality control sampling and testing. The methodology of the proposed CP-L 5120 RAP asphalt content correction factor shall be outlined in detail in the approved RAP PC Plan. At a minimum, the proposed CP-L 5120 correction factor shall identify the principal source locations of the RAP aggregate, gradation of the material tested, and specific ignition oven serial number used in all the RAP asphalt content testing. The RAP source locations, material gradation, and specific equipment used shall substantiate the CP-L 5120 asphalt content correction factor used for the testing. The substantiation must be from data gathered from historical information or specific asphalt content correction data obtained from tests performed on similar virgin aggregate sources, virgin material gradations, and the specific equipment used. D. Control of RAP Gradation (CP31 or AASHTO T-30): Frequency: 1/1000 tons of processed RAP material (minimum three tests) E. Process Control Charts shall be maintained for binder content and each screen listed in subsection 401.02(b), during addition of any RAP material to the stockpile. The Contractor shall maintain separate control charts for each RAP stockpile. The control charts shall be displayed and shall be made available, along with RAP AC extraction testing laboratory reports, to the Engineer upon request. 2. The processed RAP must be 100 percent passing the 31.5 mm (1% inch) sieve. The aggregate obtained from the processed RAP shall be 100 percent passing the 25.0 mm (1 inch) sieve. The aggregate and binder obtained from the processed RAP shall be uniform in all the measured parameters in accordance with the following: UNIFORMITY* Parameter Standard Deviation Binder Content 0.5 Percent Passing 19 mm (%") 4.0 Percent Passing 12.5 mm (1/2") 4.0 Percent Passing 9.5 mm (3A") 4.0 Percent Passing 4.75 mm (#4) 4.0 Percent Passing 2.36 mm (#8) 4.0 Percent Passing 600 µm (#30) 3.0 Percent Passing 75 µm (#200) 1.5 Uniformity is the Maximum allowable Standard Deviation of test results of processed RAP. October 19, 2023 3 REVISION OF SECTION 401 PLANT MIX PAVEMENTS - GENERAL 3. If RAP millings generated are incorporated in the same project, in accordance with CPL 5145 the Contractor shall pave with a virgin mix design until sufficient amount of processed RAP has been stockpiled and tested to allow full production of a RAP HMA mix. S ubsection 401.12 shall be deleted and replaced with the following: 401.12 Surface Conditioning. After the roadbed has been graded and compacted, the subgrade shall be trimmed to the correct elevation (+/- 0.04 feet) and cross section as shown on the plans. Only blades with machine control capable of finishing the base grade to within the specified tolerance above shall be allowed. A trimming machine shall not be used to achieve final grade unless written approval is obtained from the Engineer. If a trimming machine is approved for use, it shall be machine controlled. The machine shall not change the trimming's approved proctor for the aggregate base course material by more than 6 lbs/cubic foot. If it does, the trimmings shall not be allowed to be placed within the roadway prism. The aggregate base course shall be brought to the specified cross section elevation as shown in the plans (+/- 0.04 feet). High areas shall be trimmed to the proper elevation. Low areas in untreated bases shall be filled and compacted to a condition similar to that of the surrounding grade. Low areas between 0.5 and 1 inch below the specified elevation may be filled with hot mix asphalt. Low areas greater than 1 inch shall be filled and moisture compacted with aggregate base course material. The finished grade shall be maintained in a smooth and compacted condition until the pavement is placed. Before placing the tack coat and beginning overlay work, the surface to be tack coated shall be swept to remove accumulations of loose gravel and debris. Asphalt plant mix shall be placed only on properly constructed surfaces that are free from substances that would adversely affect the pavement quality. Contact surfaces of curbing, gutters, manholes, and other structures shall be painted with a uniform coating of asphalt cement before placing asphalt mixture against them. S ubsection 401.17, paragraph 1, shall be modified to include the following: If the Contractor can demonstrate to Weld County that all the manufacturer's recommendations were followed and the pneumatic tire roller is detrimental to the finished surface of the HMA, the Contractor may request Weld County to waive the pneumatic tire roller requirement. S ubsection 401.17 shall be revised to include the following: Pneumatic tire rollers shall not be used on SMA pavement. Steel wheel rollers shall not be used in vibratory mode when compacting HMA or SMA on bridge decks.

Per September 2022 CDOT Bridge Rating Manual Section 1.7.2, ratings for SU and EV trucks are omitted. Although the superstructure condition is POOR per the inspection report dated 12/1/2022 due to the condition of the exterior girders, visual assessment of the structure is based on barriers that have been placed along edges of the traveled lanes to prevent loading of the exterior girders. Barriers will stay in place until the bridge can be replaced. NBI 58 (Deck) = 6. NBI 59 (Super.) = 4. Rated by SEH, Inc. *NO POSTING REQUIRED* SEH Rated by: (Prim. rturne and sign Trevor K.

Sheet Subset: STRUCTURA Subset Sheets: 9 of 46 October 27, 2023 Bid Request No. B2300185, BR54/13A Bridge Replacement Project Weld County, Colorado ADDENDUM NUMBER TWO The following shall be incorporated into the CONTRACT DOCUMENTS, for the above -referenced PROJECT: Contractor Questions and Responses Revision to Section 601 of the Specifications (changes shown in red) Revision to Section 603 of the Specifications (changes shown in red) Updated Bid Tabulation Updated Plan Sheets 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. CONTRACTOR QUESTIONS AND RESPONSES Question 1: General note 9 on plan sheet 4 indicates that potholing of utilities shall be the responsibility of the contractor, and included in the work. Please verify that potholing will be paid by the potholing bid item, and not incidental to other work items. Answer 1: Yes, potholing for utilities will be paid under the potholing bid item. The contractor shall be responsible for coordinating with the County prior to scheduling the potholing so it can be tracked for payment purposes. Question 2: Earthwork notes 11 & 14 indicate that excavation required for compaction of bases of cuts and fills shall be paid for under the Reconditioning and Compaction pay item. I don't believe there is a bid item for Reconditioning and Compaction. Please clarify. Question 2: See Addendum 1, Question and Answer #10. Revised plan sheets were also issued with addendum 1. Question 3: Plan sheet 52 shows Grouted Riprap for the Riprap rundown details. Note 4 indicates that Grouted Riprap Slope and Ditch Paving will be paid by the CY. There doesn't appear to be a bid item for Grouted Riprap. Please clarify which of the riprap rundown details will be broken out and paid for separately, and which are incidental to the Embankment Protector (Type 5)(Riprap) bid item. Answer 3: Grouted riprap is incidental to all Embankment Protector (type 5)(Riprap). Note 4 on sheet 52 has been updated to show the grouted riprap is incidental to the Embankment Protector (Type 5)(Riprap). Question 4: There is a note under Revision of Section 207 Topsoil, in the Special Provisions, that states Amendments for Topsoil will not be measured and paid for separately but shall be included in the work. There is also a bid item for Compost (Mechanically Applied) that has the same acreage as the seeding bid item. Is the Compost bid item meant to cover the cost of required soil amendments, or are they separate? Stated differently, do we need to include cost for soil amendments in addition to the bid item for Compost? Answer 4: The need for additional fertilizers will be dependent upon the soil lab testing recommendations. If additional fertilizers are required, they are incidental to the cost of the seeding. It might be possible for the compost required to be applied to the topsoil to act as the fertilizer. However, in order to be considered, the compost will have to be tested showing that it meets the fertilizer requirements. If the compost does not meet the fertilizer requirements, additional fertilizer shall be applied at no additional cost to the project. Question 5: Caisson Section C on plans sheet #88 indicates #8E hoops. Reinforcement Schedule 1 and Caisson Elevation Detail (bar P14A) indicates that these bars are #7E. Please verify which bar is correct. Answer 5: The caisson reinforcement is #8E hoops. They are included in the unit cost of the caisson. The #7E P14A reinforcement is part of the column (not the caisson). The sheet has been updated to clarify this question. Question 6: Notes on plan sheets 80 & 105 indicate a maximum permitted load for SIP deck forms shall not exceed 30 PLF total for each girder. We assume that reference is for metal SIP forms. Are precast deck panels allowed on this project? Answer 6: Per the design engineer, the 30 plf max is for the SIP forms and any excess concrete in the flutes. Expanded polystyrene may be glued into the flutes to reduce the weight to be less than the 30 plf. Precast deck panels will not be allowed. The use of appropriate removable deck forms may be used. Question 7: On plan sheet 112 there is a FIO note description for Structural Steel (Galvanized) at 610 LBs. This is the same bid item quantity as 602-00025 Reinforcing Steel (Stainless). Would you mind clarifying the intent of bid item 602-00025 Reinforcing Steel (Stainless) and what it is meant to pay for? Answer 7: Per the design engineer, the table on Sheet 112 is for information only and is a CDOT standard drawing quantity for structural steel components of the standard CDOT transition. The stainless -steel reinforcement bid item 602-00025 is for the reinforcement that connects the approach slab to the abutment. See sheet 106 section 1. It is by coincidence that the quantity of stainless -steel reinforcement was similar to that shown on sheet 112 for galvanize hardware and steel. A revision to sheet 106 will be made stating the stainless -steel bars that connect the abutment to the approach slab is paid under 602-00025. Question 8: Referencing Revision of Section 102 in the Special Provisions, pages 65 and 66, it appears as though some pages may have inadvertently been left out. Please double check. There are no missing pages. Answer 8: The Weld County revision to Section 102.05 states to amend the subsection to include the 2 additional paragraphs shown in our special. Therefore, section 102.05 would contain all of the language in the CDOT 2023 Specifications plus those two paragraphs. Question 9: Would it be possible for WINFAB 2300 to be approved as an equal to the Mirafi FW300 specified in the plans and specifications? Answer 9: At this time Weld County is unable to approve alternative materials as an approved equal. Once a contractor has been selected and the contract has been awarded, the County will begin reviewing submittals submitted by the Contractor. When reviewing alternative materials, the County will review the technical specifications, installation procedures (including overlap, trenching, and anchoring), and the appropriate testing data to determine if the alternative product meets or exceeds all of the technical specifications of the Mirafi FW300. Question 10: Are electronic files available? Answer 10: Electronic CAD files will be provided to the contractor that is selected for the project. An Excel spreadsheet is not available for the bid tabulation. Question 11: Regarding the RCP culverts — Sheet 45-48, Note 3 — calls for the RCP culverts to be backfilled with flowfill from spring line to 1' above the top of the pipe. Most of the culverts have just over 1' of cover per the design drawings. If the culverts are backfilled with flowfill to 1' over the top of the pipe there will not be enough soil over the pipe to seed and grow vegetation. Please clarify what Weld County would like the contractors to do. Answer 11: The flowfill over the culverts is to extend 1 foot over the top of the pipe. If there is a conflict with getting enough topsoil over the top of the pipe, the extents of the flowfill will have to adjusted in the field. Any field adjustments that occur shall be coordinated with the Engineer and Inspector. Question 12: Regarding the RCP culverts — Each of these runs goes from FES to FES. Based on that would the County allow for the contractors to use whole joints of RCP pipe to allow for the use of bell end and spigot end FES? If that is not allowable what kind of connection will the county require between a cut section of pipe and the FES? Answer 12: The use of whole sticks of RCP will not be allowed as it can cause issues with the proposed grading and pipe hydraulics. In order to ensure that the bell and spigot ends are located at the FES, pieces of cut pipe shall be as close to the middle of the pipe run as possible. Per the Weld County Revision to Section 603.07(a), concrete collars are required for all non-standard joints (i.e., not tongue and groove or bell and spigot) and at all connections to existing pipes. Question 13: Where is the 251 CY of Structure Backfill (Class 1) located? Answer 13: The Structure Backfill (Class 1) is located on the outside of the abutments and wingwalls. It extends to the riprap elevation. Question 14: How is the Concrete Slope and Ditch Paving shown in Section B on sheet 52 of 152 to be paid that is associated with the embankment protector? Answer 14: Grouted riprap is incidental to all Embankment Protector (type 5) Riprap. Note 4 will be updated to reflect the correct pay item and a revised sheet has been included with this addendum. Question 15: Is there a 404 permit that accompanies the Nationwide Permit 14? Answer 15: The ACOE 404 permit was included with the original set of items that was posted to BidNet. The document is titled NOW -2023-00895 20230925 NWP 14 Letter.pdf. Question 16: Is Colorado State Sales tax the only tax the contractor is exempt or is the contractor also exempt from Weld County Sales tax on permanent materials? Answer 16: Weld County does not have a county sales tax. Question 17: On page 194 of the project specifications, the pay unit for dewatering is "days" and on the schedule of values the pay unit is "LS". What is the pay unit for dewatering? Answer 17: The pay unit for dewatering was changed in the revised bid tabulation that was included with Addendum 1. Question 18: Our take -off of the subgrade area that will receive Geogrid Tensar NX 650 is approximately 6,000 SY. How was the plan quantity of 10,000 SY established? Do we need to place two layers of geogrid? Answer 18: The quantity of Tensar NX650 to be used between the aggregate base course (ABC) and subgrade is approximately 6,000 SY. The remaining quantity of approximately 4,000 SY is a contingency. The contingency will only be used at the direction of the Engineer. Question 19: Are the signs for the temporary closure going to be required to be ground mounted? Answer 19: No, the signs for the temporary closure are not required to be ground mounted. However, the ground mounted signs will be easier to maintain over the course of the project because they are harder to move or get knocked over. The detour will be active during the winter when snow removal activities will be occurring. The County will drive the detour daily to verify the correct signage in still in place. If the signs are missing, moved, or knocked over, the contractor will be notified and the traffic control subcontractor will have to come back out and set them up again. Question 20: Can the proposals be submitted through BidNet instead of email? Answer 20: Weld County's Revision to Section 102.01 states all bids are to be emailed to bids@weldgov.com. The County's email system accepts attachments up to 25 MB in size. If the contractor's proposal is larger than 25 MB in size, please contact the Engineer in advance of the due date and time to arrange for an alternate method of delivery. Question 21: Removal of Nests and netting — is this expected with the time of the project? Answer 21: The specification states that birds try to build or occupy their nests between April 1 and August 31. Since the project is going to be constructed during that timeframe, it is possible that netting and removal of nests will be required depending on how many nests the birds are trying to build. Question 22: Can you clarify where the large quantity of Reinforcement (Black) is? Answer 22: The black reinforcing steel is in the abutments and piers. Question 23: Note 3 on Sheet 105 states that the waterproofing membrane shall be prefabricated, reinforcement membrane with primer, however there is no further information in the project documents about this. Is the intent to follow CDOT specs or is there a different design/specification that needs to be followed? Answer 23: A prefabricated, reinforcement membrane with primer is required for use as the waterproofing membrane and it shall meet the CDOT specifications for such a membrane. Question 24: The Concrete Structure Notes on Sheet 80 require concrete properties that may vary from a CDOT CI D APL mix. Is this acceptable? Answer 24: The Specifications require the slump to be within +/- 2 inches of the slump shown on the Form 1373 and the air content has to be between 5 and 8 percent. The Concrete Structure Notes require that the slump be between 1.5 and 3.5 inches and the air content has to be between 5 and 8%. There does not appear to be a conflict between the two requirements. The Form 1373 is the approval for the mix design. Even if the concrete mix design is on the CDOT APL, the contractor still has to provide the mix design along with all testing data for review and approval. It may be necessary for the contractor to supply a mix design that is not on the CDOT APL. Question 25: CDOT allows 80% strength for backfilling, however the general Notes require 4500psi — for scheduling purposes can CDOT specs be followed? Answer 25: Forms may be stripped once the concrete reaches 80% of the 28 day strength while loading and backfilling of the piers and abutments cannot occur until 100% of the 28 day strength has been obtained. The use of maturity meters in the concrete is required so concrete strengths can be obtained at any time. The maturity meter readings have to be provided to the Engineer once they are obtained so they can be compared to the maturity curve. A maturity curve is required to be developed as part of the concrete mix design approval process. Question 26: The Design data on the Structural Notes sheet imply that SIP deck from can be used but cannot exceed 30 PLF, however no plans were provided and precast deck panels may exceed this. Are metal decking or precast panel stay -in -place deck forms allowed? Answer 26: The 30 plf max is for the SIP forms and any excess concrete in the flutes. Expanded polystyrene may be glued into the flutes to reduce the weight to be less than the 30 plf. Precast deck panels will not be allowed. The use of appropriate removable deck forms may be used. Question 27: The Bridge Rail Type 10M on the curb is not a legal railing (height) with the sidewalks. Does the County intend to change the railing design? Answer 27: Drawings S-832, S-833, and S-834 show the wrong height dimension on some of the views. The correct height dimension is shown on the typical section on S-832, Revised sheets have been included with this addendum. Question 28: It appears that new fencing has already been installed at the temp easements for utility work — is this fence in the removal quantities? Answer 28: Yes, the removal fence pay item includes the removal of the temporary fencing. Question 29: Is the cutoff wall at the embankment protectors paid for via the Concrete CI D (Cutoff Wall) item? Answer 29: Yes, the cutoff walls are incidental to the embankment protectors. In fact, all items associated with the construction of the embankment protectors are incidental to the cost of the embankment protector. Question 30: Is a design sealed by a licensed professional engineer for the temporary steam crossing necessary with a design already completed in the plans and the risk being on the contractor to install, maintain, replace (if necessary)?) Answer 30: If the contractor wishes to change the design of the temporary stream crossing, they will have to have a licensed professional engineer design and seal the new design. The new design will then have to be submitted to the Engineer for review and approval. Question 31: There is concern of unreliable CSL data on the caissons with H -Piles in them as they may result in inconclusive data/results in the portion of the caissons with pile in it — how will this be handled? Answer 31: Any inconclusive CSL results will require exposing the top 5 feet of the abutment caisson to verify the caisson is constructed according to the plans and specifications. Visual inspection of the top 5 feet of the caissons during tremie/pouring of the caissons may be sufficient if visual inspection is possible. The option of having permanent casing at the top 5 feet of the caisson can be submitted as a means of ensuring there is no caving of the hole. There will be no additional payment for leaving casing for the top 5 feet. No other permanent casing shall be allowed anywhere else on the project. Question 32: The deck pour sequence provided does not make sense as this is needed with continual beams over piers with phase lines at the point of reflection, which is not the case in this bridge so unnecessary joints are being added to the deck and may result in the deadload deflection not being accurate. Can the deck be poured monolithically? Answer 32: As the concrete cures and becomes less plastic there is a risk of cracking over the piers. The structure develops continuity as the concrete cures and successive pours will create crock in the deck as the concrete starts to "set". Most of the deflection takes place during pouring of the concrete in the positive moment regions. The contractor shall submit a deck pour sequence plan including computations for girder camber strip after the girders have been erected and the tops of the girders have been surveyed. The contractor is responsible for ensuring the construction of the deck meets finished deck grade elevations. The deck pour sequence in the plans were developed to minimize the risk of the deck cracking over the piers during the deck pours. Question 33: The project docs require Professional Liability Insurance — if a contractor does not have this due to subcontracting consultants for any engineered components, is this insurance required by the GC or can subconsultants COI with the required coverage be adequate? Answer 33 Per Section 107.16 of the specification and the contract documents require professional liability insurance to be carried by both the contractor and subcontractor when construction surveying or survey monumentation is included with the project. This project includes construction surveying so professional liability is required. It has been the County's experience that the Contractor usually has an in-house employee that is providing surveying for some items of the project so professional liability would be required for the Contractor as well as for the subcontractor providing surveying services. Question 34: The project documents require builder's risk and that it should include flood (including water damage), however it also states that Flood damage coverage is not required for within the floodway or 100 - year floodplain. Can the County clarify if this project is within the floodway or 100 -year floodplain? Answer 34: Depending on the insurance provider, builders' risk insurance may or may not be available because this project is in the 100 -year floodplain as well as the floodway. Regardless of whether or not Builders' Risk insurance is available, the Contractor shall bear all the risk associated with any and all loss resulting from flooding events during construction. In other words, the County's contract makes the Contractor responsible for protecting all the work form damages. If damages happen as a result of flooding, those damages shall be repaired at no additional cost to the County per Weld County's Revision to Section 107.18 and the contract documents.

S ubsection 601.05(5) shall be deleted and replaced with the following: (5) Class P concrete shall include AASHTO T97 (ASTM C78) Flexural Strength of Concrete (Using Simple Beam with Third -Point Loading). At least two specimens will be tested at 7 days and four specimens at 28 days. The laboratory trial mix shall produce a flexural strength at 28 days of at least 700 psi. S ubsection 601.09(a) shall be deleted and replaced with the following: (a) Design. Forms shall be mortar tight and sufficiently rigid to prevent distortion due to the pressure of the concrete and other loads incidental to the concrete operations, including vibration. The rate of depositing concrete in forms shall be controlled to prevent deflections of the form panels in excess of the deflections permitted by these specifications. Forms for exposed concrete surfaces shall be designed and constructed so that the formed surface of the concrete does not undulate excessively in any direction between studs, joists, form stiffeners, form fasteners, or wales. Undulations exceeding 3/32 inch between the center -to -center distance of studs, joists, form stiffeners, form fasteners, or wales will be considered excessive. Should any form or forming system, even though previously approved for use, produce a concrete surface with excessive undulations, its use shall be discontinued until modifications satisfactory to the Engineer have been made. Portions of concrete structures with surface undulations in excess of the limits may be rejected by the Engineer. Forms for drainage inlets may be constructed of any suitable material that will produce a structure with the inside dimensions and at least the wall thicknesses shown on the plans. Undulations of finished interior wall surfaces shall not exceed 0.5 inch. Where called for in the Contract, the Contractor shall design and construct a permanent bridge deck forming system. Based on what is indicated, the Contractor will be permitted one of the following sets of options: (1) If the plans indicate that permanent deck forms are optional, the Contractor shall have the option of constructing a cast- in -place bridge deck using conventional forms, a full -depth cast -in -place bridge deck using permanent steel bridge deck forms.

Scope of Proposal NEP • a a a a .S_ KRAEMER® NORTH AMERICA Bridge 54-13A Replacement Project A. SCOPE OF PROPOSAL Kraemer's Understanding of Scope and Objectives Kraemer North America, LLC (Kraemer) is pleased to present our RFQ/RFP response to Weld County Public Works (Weld County) for the Bridge 54-13A Replacement project. Kraemer has the qualifications, expertise, and available resources to deliver success on this exciting project. We understand the objectives of this project and are uniquely qualified to deliver services that will result in early completion and opening of traffic to the newly constructed bridge over the Big Thompson River. In doing so, we will deliver excellence in quality construction for all scope elements including embankment, HMA paving, drainage systems, and erosion control. Kraemer will partner with Weld County to deliver a collaborative project ahead of schedule and under budget. This partnership is founded on consistent communication at all steps of the way, starting from day one of selection on the project through closeout of all documentation after opening. Our entire management team, introduced on page 2 of this section, will anticipate potential issues weeks in advance of when they need to be addressed through our work activity planning and five - week look ahead schedule process. We will be proactive, not reactive, in solving these issues. Kraemer's approach includes a commitment to self -perform many of the salient features of work (including earthwork, drainage, and all structure work) on this project, allowing us to provide the experience and resources that will ensure the highest quality and a certainty of outcome for schedule success, including our commitment to open to traffic two months early. Coupled with that approach, we will manage our subcontractors to ensure schedule is met for those specialty disciplines (electrical, asphalt paving, traffic control) performed by key subcontactors. Our robust management staff will communicate with subs and suppliers consistently and will use our proven subcontractor management tools and processes to eliminate risk of schedule impacts from third parties. Kraemer will deliver high quality work that will exceed Weld County standards. This will result in project elements that will avoid maintenance needs or repairs in future years. Kraemer's commitment to "Quality. Safety. Excellence." will serve as our guide for delivering success. Our methodology for project quality excellence is based on our approach to Work Activity Planning. We have already started planning all of our method statements for major salient activities, and will use the successful plans from our past projects in the area (including numerous bridges over the Big Thompson, Little Thompson, Poudre, and St. Vrain rivers). This process includes a detailed analysis of contract requirements, quality expectations, material and equipment resources needed, detailed schedules for daily work execution, safety and hazard analysis, owner's inspection/ testing requirements, and labor productions to ensure successful execution of the work activity. We look forward to sharing all work activity plans and method statements with Weld County representatives well in advance of starting the work to ensure we are all on the same page with expectations. These plans are communicated with our crews (and subcontractors, if applicable) during the morning team meetings each day to set forth a clear expectation for all to ensure excellence in safety and quality of all aspects of the work. Figure .1: Kraemer recently completedthree bridges ver the Big 'Thompson River, just upstream o1 WCR 54. ()cation Kraemer's management process includes early communication to proactively manage landowner and utility coordination. We will ensure landowners and farmers have access to their properties at all times of construction, and that changes in traffic patterns or access are communicated well in advance. We have included cost in our estimate for all-weather access in and out of their fields and homes throughout the duration of the project. Regarding the utilities, we will use our experience over the past six years working with the same utility companies on our I-25 North Express Lanes project to manage any overlap that may occur between relocations and our work after construction starts. Kraemer will communicate with the County early to remain on the same page and work collaboratively to avoid any utility conflicts. Our commitment is to not allow utilities to impact our schedule. We will own that risk and manage effectively to ensure no impacts to our schedule commitments. Success on this project will also be defined by our approach to environmental management. Effective erosion control measures will be implemented and managed to remain fully in compliance with permit and regulatory requirements. This approach includes daily (not just weekly) inspections, and commitment from crews for timely maintenance of all best management practices. This process includes consistent communication with the Owner's staff to ensure we, as a team, put the Project First along every step of the way in building this project. Decisions will always be made in the best interests of the project. It is Kraemer's goal to begin a long relationship with Weld County on this project. Kraemer is committed to completing this project with no change orders resulting in additional costs unless such change orders are initiated by the County. Kraemer North America, LLC Quality. Safety. Excellence 1 SCOPE OF PROPOSAL We have a 112 -year company history that always puts our values and commitment to building a relationship with the owner ahead of any short term gain on any minor project issue. In the Project Critical Issues section, we explain further how we have approached this proposal and estimate to avoid conflicts, minor change requests, and future issues. In fact, we are very proud to say that we have successfully completed over $1.58 worth of local transportation work in the past two decades with this same approach, and continue to be chosen again and again by owners along the Front Range based on our focus on delivering excellence in quality and safety while partnering closely to ensure project goals are met. Kraemer's Team to Deliver Success The key personnel committed for success on this project and shown below are just wrapping up work on the 1-25 North Express Lanes Segments 7 & 8 Design -Build for CDOT, which was a $486M improvement of 1-25 from SH402 to Prospect Road. Tyler Rue served as Construction Manager on the Project; Brandon Meis was Project Superintendent; Kaitlin Callanan was Project Engineer / Quality Manager; Greg Frazee worked closely in partnership with Tyler as Assistant Project Manager; and Alex Smith led our team as Environmental Manager. As defined in section (d) below, our staff is fully available for the project starting December 1st. The timing of this project is perfect for this entire team to dive in fully to deliver success for Weld County. Kraemer's team is led by Weld County residents that are proud to deliver success for the community in which they live, work, and play. Over 50% of our workforce (operators, carpenters, laborers) are Weld County residents. We look forward to committing these same local residents on the WCR 54 project as well.

Safety. Excellence Z Tyler Rue, Project Manager - Tyler brings over twelve (12) years experience in managing complex bridge and roadway projects, with a focus on planning of the work and communication of our plan to all involved (crews, inspectors, owners, etc.). Prior to 2011, Tyler interned with Larimer County Engineering Department as an Inspector. From this internship, Tyler learned the importance of timeliness of daily reporting and testing documentation, and has carried that commitment through all of his projects. Tyler has worked closely in partnership with Greg Frazee over the past six years on Kraemer's work on 1-25, immediately west of this project. Prior to leading the I-25 North Express Lanes project as Construction Manager, Tyler led Kraemer's work on the I-25 Cimarron project in Colorado Springs, where he worked closely with our environmental team to construct four structures over Fountain and Monument Creek. Brandon Meis, Superintendent- Brandon has over nineteen (19) years experience leading Kraemer's work on construction on bridges similar to WCR 54 over the Big Thompson. He started his career with Kraemer as a carpenter, working progressively up to a Superintendent role eight years ago. Brandon has led the construction of all new bridges along the I-25 North Express Lanes, working closely with Tyler, Greg, and Kaitlin to ensure the highest quality excellence was delivered on our work. Specifically, Brandon initiated the plan to expedite construction of the three separate bridges over the Big Thompson River, minimizing impacts to the traveling public with accelerated construction of each phase of bridge demolition and reconstruction. Kaitlin Callanan, Project Engineer - Kaitlin has over eight (8) years experience working with Kraemer on various bridge replacement projects, including the I-25 North Express Lanes as well as the I-25 and Arapahoe Road Interchange. Kaitlin leads Kraemer's process for Quality Control Inspection of all work prior to releasing for next steps of construction. Her attention to detail and thorough approach to transparent documentation on the I-25 North Express Lanes project has helped put Kraemer in a position to seamlessly close out all NCR's and final paperwork as work wraps up this fall. Kraemer's Experience With Similar Work Kraemer's Mountain West region has over a 40 -year history of building large scale heavy civil road and bridge construction projects very similar to WCR 54 over the Big Thompson River. Figure 3 below includes a list of projects with similar elements of work that were completed within the past 5 years. On the next two pages, we have provided additional details on some of the projects that have all of the same features of work and demonstrate added familiarity with the challenges we will face, and overcome, on this project together with Weld County.

Safety. Excellence 3 1-25 North Express Lanes Segments 7 & 8 Three (3) Bridges over the Big Thompson River (I-25 Northbound, 1-25 Southbound, and East Frontage Rd) (Loveland, CO) Kraemer constructed three separate major structures over the Big Thompson River, just upstream from the WCR 54 crossing. All three included demolition of the existing bridges over the Big Thompson; water control and access for working in and around sensitive areas that required an Army Corps of Engineers 404 permit; caisson foundations at pier locations which included CSL testing and dewatering; erection of precast girders from access pads along Big Thompson River that avoided environmental impacts; daily erosion control inspections and maintenance of best management practices to comply with all Army Corps 404 permit requirements as well as CDPHE SWMP requirements; and all other features to tie in roadway embankment and paving on either side of the Big Thompson River. For construction of the East Frontage Rd (EFR) over the Big Thompson, Kraemer initiated a full roadway closure with detours for the EFR traffic, similar to what will be required at WCR 54. The full closure was implemented in March of 2020, and opened fully to traffic ahead of originally planned schedule in September of 2020, for a total closure of less than 180 days. East Frontage Rd over Hillsboro Tributary (Johnstown, CO) Similar to the bridge replacements described above, Kraemer also removed and replaced a single span bridge on the 1-25 East Frontage Rd over the Hillsboro Tributary, immediately south of the SH402 over I-25 interchange. This work involved careful planning with access pads to avoid environmentally sensitive wetlands. The EFR was closed in March of 2023 and re -opened in May 2023, limiting the overall closure to 82 days total. I-25 Northbound and I-25 Southbound over Poudre River (Tinmath, CO) Kraemer replaced the major 1-25 structures over the Cache la Poudre River as part of the I-25 North Express Lanes project as well. This work included major substructure elements constructed adjacent to the Poudre, with careful attention to limit impacts to this environmentally sensitive area. This four span structure was constructed in three different phases, each coordinated to avoid heavy run-off in late Spring. Demolition of the existing bridges over the Poudre was completed by sawcutting slabs and removing sections of the bridge deck to ensure no debris fell into the river. Kraemer North America, LLC Quality. Safety. Excellence 4 A. SCOPE OF PROPOSAL r 1-25 South Gap CMGC 1-25 over Plum Creek (Larkspur, CO) As part of the major 18 -mile highway expansion from Castle Rock to Monument, Kraemer replaced two major 1-25 bridges over Plum Creek in Larkspur, CO. The work required coordinating our efforts to avoid the Preble's Meadow Jumping Mouse habitat, as well as complying with all requirements of the 404 permit. The structures were three -span concrete precast girder bridges over the creek, with water control and final stabilization similar to WCR 54. 1-25 Cimarron Design -Build US 24 over Fountain Creek (Colorado Springs, CO) Kraemer's team, led by Project Manager Tyler Rue, removed the existing US24 bridge over Fountain Creek and replaced it with a two -span precast girder bridge. On this project, Tyler worked closely with Greg Frazee to complete all major roadway reconstruction along 1-25 and US 24 in this busy interchange, minimizing impacts to traffic with an efficient phasing approach that accelerated our overall construction schedule. Kraemer initiated a new horizontal and vertical profile to accommodate 12 feet of vertical clearance for the trail below, and subsequently constructed trail and creek improvements throughout this reach of Fountain Creek.

Safety. Excellence 5 With Kraemer's 40 -year experience in Northern Colorado and numerous bridge projects over the Big Thompson River, we have a unique understanding of critical issues on this project. In addition, we have thoroughly reviewed the project specifications and Weld County requirements from the prebid meeting. As proven in our project history, we take a Project First approach to overcome project challenges without submitting any claims or issues to our owners. Below are the major issues we foresee with this project along with Kraemer's unique approach that will mitigate these challenges without any additional cost to Weld County. Cost Certainty and Proactive Change Management Kraemer understands the County's goal is to have zero change orders unless initiated by the County. While preparing our bid, we have done a thorough analysis of the plans and specifications such as independent quantity checks, scope of work verification, and a detailed schedule analysis with our subcontractors and suppliers. Because of this analysis our price proposal includes all cost and quantities for all scopes of work shown in the plans Kraemer accepts all bid items to be paid at plan quantity without any overruns for work that is shown on the plans. This commitment gives Weld County early price certainty and comfort to know that no additional change orders will be requested by Kraemer, and the only increase to our bid proposal will be if additional work is requested by the County. Accelerated Mobilization and Project Startup Given the accelerated schedule of the project and need to start construction immediately in January. Weld County needs a contractor that can quickly mobilize, establish a field office, and diligently prepare submittals to procure permanent materials. With Kraemer completing the $486M I-25 North Express Lane project, we are committing the management staff, field personnel and equipment from this project to move to WCR 54. These established resources already in Northern Colorado allow us to quickly mobilize and be ready to start immediately on January 2nd. In addition, we already have an established field office located 5 miles from the project just west of the I-25 and SH 402 interchange for this project. This provides ample office space with indoor plumbing and lab access for Weld County and Kraemer staff to co -locate to immediately begin coordination and planning until the onsite field office is setup. Kraemer's close proximity also supports accelerating the construction start up as this office and lab are available for Weld County staff to immediately utilize after selection. We understand the County's requirement for a submittal on all items incorporated into the project. In addition, numerous long lead materials are driving the project schedule such as girders, bridge railing, and rebar. Preparing and submitting shop drawings and submittals for every material incorporated into the project will be critical to meeting the schedule. Therefore, Kraemer has included key personnel in our proposal that will focus on early preparation and review of submittals to the County well in advance of implementation in the field. Kraemer's early submittal commitment, ability to immediately co -locate, and manpower and equipment resources already available will allow for an accelerated mobilization that will avoid schedule issues and minimize public impacts. Utility Relocations Kraemer will continue Weld County's progress in coordinating all utility company relocations as a key to project success. Project Manager, Tyler, and Project Engineer, Kaitlin, will be responsible for coordination with Xcel, DCP gas, Century Link, PVREA, and LTWD immediately after selection. Tyler and Kaitlin both managed major utility relocations with these same companies for the last six years on our I-25 North Express Lanes Segments 7 & 8 Project without any issues or delays. Our established relationships and utility management approach such as weekly coordination meetings, field surveys, assisting with access, and early potholing within property easements. Potholing will accelerate the utility companies' relocation process and avoid impacts to the schedule. Figure #4: Kraemer coordinated utility relocations to construct the new bridge over the Big Thompson If 3rd party companies like Xcel and Century Link are delayed outside the control of Kraemer, we will take a project first approach to re -sequence construction and find opportunities to keep progressing the work. For example, Kraemer can mitigate gas and fiber relocation delays at no additional cost by: • Utilizing vacuum trucks around the existing gas lines to keep the caissons progressing. Re -sequencing the riprap installation under the bridge until later in the project to avoid impacting any Xcel's gas line. Kraemer North America, LLC Quality. Safety. Excellence 6 �I Bri ge 4 3A B. CRITICAL ISSUES • Modifying the location of the temporary stream crossing to avoid impacting the gas relocation. • Temporarily supporting Century Link's existing fiber or temporary relocate it off the existing bridge until the new conduit is bored. All of these mitigation and coordination efforts are included in our price proposal. Minimizing Public Impacts and Adjacent landowner and Agency Coordination Kraemer understands the schedule importance to remove and replace the bridge per the required schedule dates to minimize impacts to the public. As outlined in our proposal, Kraemer's robust approach to project staffing and planning will provide the County with a certainty of outcome, as Kraemer has done this exact same thing before in Northern Colorado. Tyler, Brandon, and Kaitlin led Kraemer's operations to construct the entire 1-25 and SH 402 interchange, just three miles away from this project, in an accelerated 120 day closure. Tyler coordinated all traffic control and worked closely with the North 1-25 Coalition which included Weld County Deputy Public Works Director, Elizabeth Relford, during the planning process. From our experience, we understand the planning and coordination effort required to accelerate bridge construction during a full closure. Because of this we are confident in our commitment to reopen the roadway by July 1, 2024. _ Figure 45: Kraemer constructed the new SH 402 interchange in an accelerated 120 day closure In additon, we commit to the following landowner and agency accommodations to further minimize impacts to the public: • Tyler will bring his knowledge of CDOT and Larimer County traffic control permit process to this project and ensure all traffic control permits and detour routes within neighboring jurisdictions are obtained in a timely manner. • He will also work closely with all adjacent landowners to provide all-weather access to driveways at all times during construction. We will offer weekly updates and one -one meetings to keep property owners informed on construction progress and changes. • All temporary easements will be surveyed and delineated with construction fencing to ensure construction activities do not encroach outside of the agreements already obtained by Weld County. • We also commit to performing snow removal within the closure limits to each driveway to maintain landowner access in the winter months as well as coordinating with Weld County's snow desk as needed. • Kraemer staff will drive the detour route daily to ensure signs and traffic control devices are properly functioning and informative. We will not depend on only our traffic control subcontractor to perform this inspection. Kraemer takes pride in working with the community to minimize impacts during construction on all our projects, and we strive to be good neighbors throughout the project. "As I listened during our partnering .cession, I was struck by the fact that you just can't write a spec dial details how a contractor should treat the community they are impacting with their work. The kinds of things Kraemer has done here are not written in the contract or on a plan sheet.. The origins are found in the culture of the company and in the hearts of their employees." Toni Warne, former UDOT Director. Partnering Facilitator, Woodmen/Academy Interchange Project Water Control and Environmental Management Protecting the natural environment and compliance with the Army Corps 404 permits, dewatering and storm water permits will be a critical issue on the project. The temporary stream crossing, wetland mitigation, dewatering, dust control, stream diverging and protection during bridge demo is the forefront of these issues. To ensure permit compliance with these operations we have included the following commitments in our price proposal: • Construction fencing around sensitive wetlands and no work areas to keep construction personnel from entering. Kraemer North America, LLC Quality. Safety. Excellence 7 B. CRITICAL ISSUES • Site Specific training to all employees working on the project informing them of sensitive environmental areas to avoid onsite. • Vacuuming the slurry from any sawcutting of the existing bridge deck during demolition to ensure contaminated water does not fall into the stream or sensitive area below. • Utilizing cranes to pick and remove the existing girders and bridge deck over the river and avoid dropping rubble to the ground and avoiding contaminats from entering the creek. • Providing netting and protection so debris from the new bridge construction does not fall into the river. • Multiple mobilizations from our landscaping subcontractor to implement final stabilization and seeding as soon as an area is completed to help expedite closing the permit. A fully lined stream diversion to fully separate the work zone from the Big Thompson River in compliance with CDPHE requirements. This diversion will also minimize impacts from high water and snow runoff. • Elevated access roads and crane pads to avoid a work shut down because of high water. Vac Trucks to remove any groundwater from within the caissons prior to concrete placement. • Full time water truck for dust control efforts. • Dewatering pumping through filter bags for rip rap and storm sewer installation. • In addition to Weld County requirements we will use Compliance Wise software to track inspections, site maps, photos, calendars, and all other documentation required by CDPHE and the Army Corps. • Early clear and grubbing and bridge removal to mitigate migratory bird nesting locations prior to March 31st Figure #6: Alex Smith managed the final stabilization of the new 1-25 Structure over the Big Thompson In addition, we have included a full-time Environmental Manager, Alex Smith in our proposal. Alex will perform daily inspections, close findings promptly, and coordinate with Weld County Inspectors. For the last six years, Alex has led environmental compliance on our 1-25 North Express Lane projects that successfully completed i 4 miles of highway construction, temporary stream crossings over the Big Thompson and Poudre Rivers, and dewatering testing without any violations or permit noncompliance. i "The transparency and honesty that Alex brings to the job allows me to trust his work and easily verify conformance to environmental requirements... Alex is an expert in managing the workload c f `'_field staf, environmental subs who are brought into the project for various activities, and environmental schedules to ensure that environmental submittals and activities are performed on time, allowing his team to move ahead with the overall project schedule. He oversees all environmental aspects of the project including migratory bird surveys and protections, wetland and waters of the US permitting compliance, Preble's meadow jumping mouse habitat protection and restoration, hazardous materials abatement prior to demolition activities, protection of historic properties, and stormwater compliance." -Jennifer Gorek, Senior Environmental Project Manager, JUB B Engineers Caisson Installation and CSL Testing Because of Kraemer's bridge experience and insight into northern Colorado geology, we understand how critical caisson installation procedures are to obtain passing CSL tests. We have a developed a quality process included in our price proposal for caisson installation that includes: • Cleaning of the caisson before concrete placement. • Temporary casing to support the overburden, a rebar cage support template to ensure it is supported during placement. • Utilizing trusted drilling subcontractors that are familiar with CSL testing requirements. • A concrete slab on grade at the top of pier caissons to use for grade control and a layout template to ensure correct location and elevation of the caissons. Even with these best practices and procedures, sometimes anomalies occur outside our control due to sluffing of material, water infiltration and fragmented bedrock. To overcome these uncontrollable possibilities, Kraemer's includes drilling an additional depth of 3ft into bedrock for all caissons at no additional cost. This gives the engineer of record three additional feet of skin friction to overcome any capacity loss because of an anomaly. This additional capacity and best construction practices commitment gives the County the confidence that the caissons will be installed with the highest quality and that any small CSL anomaly will be mitigated with the additional capacity avoiding any delays to the schedule. Kraemer North America, LLC Quality. Safety. Excellence 8 Bridge 54-13A B CRITICAL ISSUES Figure': Succestul installation of pier caissons with passing CSI, tests on the new 1-23 Structure over the Big Thompson Bridge Girders 60 -Day Cambers Actual girder cambers are a risk to meeting the 60 day camber requirement included in the plans. To overcome this, Kraemer has coordinated fabrication dates with our supplier as early as possible giving the girder the maximum amount of time to reach the desired camber before casting the bridge deck. We have also included in our proposal to frequently measure the cambers in our supplier's yard and apply weights to the girders should the cambers need to be controlled before installation. This added effort included in our proposal will ensure this critical structural design component is obtained during construction without any schedule delays. Material Management Kraemer understands the unique requirements from Weld County on earthwork and other permanent materials, and have committed to the following in our price proposal to avoid issues in the field. • To maximize the benefit to Weld County we will implement a two part asphalt removal process. First mill "clean millings" to within 1" of the bottom of existing asphalt to provide them to Weld County. Then a second millings pass will incorporate the bottom 1" of dirty milling into the roadway embankment. • Purchase of virgin aggregate base course from a reputable local commercial source. Early testing of onsite topsoil per the National Association for Proficiency Testing to identify compost and fertilizer additives requirements well in advance for Weld County review. * Kraemer will ensure all long lead time procurement of materials do not affect our overall construction schedule, and the planned early opening of WCR 54. * Early development of the non-standard 4,500 psi BZ mix design for the caisson concrete to avoid schedule delays. • Tyler and Greg brought Weld County's innovative pavement design to CDOT's I-25 North Express Lane Project and installed over 2 million square yards of mechanically reinforced base course section. We understand Weld County's design requirements and procedures to install this critical roadway section • Flexibility to salvage materials such as exisitng guardrail and cattle guards for weld County Maintenance's use. • Purchase of embankment material from a commercial source that guarantees meeting the R40 requirement and avoiding the risk of unknown R -value from unreputable dirt sources. This approach will eliminate the schedule risk associated with mining permits and any additional testing. • Avoid using onsite and blended material in the roadway prism to avoid the risk of failing R -value and inconsistent embankment. We have thoroughly analyzed the dirt flow and believe there is ample locations outside of the roadway embankment to utilize onsite material. Figure °8: Kraemer Earth" orL crews excad at i ng embankment from a reputable Weld Count) pit for our 1-25 Express Lanes Project Communication and Problem Solving Communication and problem solving with Weld County staff will be a key to successfully completing this project. Kraemer takes pride in preplanning our work to identify problems before they occur and partnering with Weld County to develop solutions in the best interest of the project. For example, our 5 -week look ahead schedule provides advance notice of when activities will occur in the field. Then within one week of the activity occurring we will hold pre -activity meetings with Weld County to discuss in detail the method statement, procedures, specification requirements, testing frequency and potential issues. This communication will ensure the County's goals are incorporated into our planning process and potential issues are mitigated before construction begins. Kraemer North America, LLC Quality. Safety. Excellence 9 C. Project Control IMPEL® KRAEMER NORTH AMERICA Bridge 54-13A Replacement Project Bridge 54-13A C. PROJECT CONTROL Construction and Subcontractor Cost Control Kraemer's cost control began during bid development with a detailed quantity verification of each bid item and included puantity overruns, in our price proposal. Because of this effort, Kraemer can confidently commit to accepting as final payment the quantities and unit prices included in the plans without any overruns. We will also look for opportunities to underrun bid items where possible and reduce cost to Weld County. For example: • We have included the risk of asphalt and fuel cost adjustments in our proposal and therefore declined the force account cost adjustments. This approach provides early cost certainty to Weld County and an immediate gain on the overall budget. • As part of our detailed approach to environmental management, we will be efficient with erosion control devices and install in locations that minimize resets. • We will stockpile existing rip rap onsite for use in unsuitable soils if needed with the goal to underrun some of the contingency bid items for Rock Fill or Unsuitable Material. We also commit to provide a monthly progress payment report to Weld County that will provide a detailed analysis of each bid item to inform the County on percent complete and underrun opportunities. We also will provide a monthly draw down schedule to forecast expenditures by month to help the county with cash management. This results in updated cost control and forecasting of the total project budget each month to provide accurate information on the total cost of the project. Since Kraemer is self -performing the majority of the work including all earthwork, drainage, rip rap, and structures, our dependency on subcontractors is minimal. This commitment to self -perform the major scope elements further reduces cost risk to the county. For minor subcontracted scope elements, we take the same approach with managing subcontractor cost, by reviewing monthly quantities and percent complete to ensure our cost of subcontractors is included in the total project analysis. Plus, we commit to accepting the risk on subcontractor quantity overruns at no additional cost to the county. Federal, State and Local Procedure Compliance Included in our price proposal is our document control and compliance manager, Samantha Marko, located in our regional office. Her job is to ensure all compliance with Federal, State, and Local reporting requirements on the project. For example, Samantha will manage the following: • Prompt Payment requirements by processing invoices and paying subcontractors and suppliers within 7 days of receiving payment as required by state and federal law. • Background checks and ensuring all employees have completed E -Verify and are eligible to work per the Department of Homeland Security. • Tax payments are properly reported for all construction materials. • Wage compliance and payrolls are meeting all state and federal requirements. • Equal Employment Opportunity, Anti Harassment, and Work place violence polices are enforced on the project. • Ensure Subcontractors compliance with all the items stated above. Approach to Quality Management Kraemer is committed to providing quality services and products in support of our commitment to "Quality. Safety. Excellence". We understand the expectations of Weld County to exceed the specification requirements and deliver a high -quality project. As an organization and as individuals, we strive to deliver quality the first time, seek continual improvement of our work processes, and will monitor our performance as an on -going activity. We commit to providing a framework for establishing and reviewing these quality goals. We commit to providing the necessary resources and training to support the achievement of our quality objectives. We are accountable for the facilities we construct and will work collaboratively with owners and partners who trust us to deliver their programs. Included in our proposal is our Regional Quality Manager, Stefan Hennig, to provide oversight of our quality program in Colorado and will do the same for our work with Weld County. Stefan has led four Design -Build quality programs including the I-25 North Express Lane Project and has set the standards for each of our project processes. Stefan has developed proven Construction Quality Management Processes (CQMPs) through our lessons learned on bridge and earthwork projects for the last two decades. These CQMPs will be the basis of method statements submitted to Weld County, and will help expedite the submittals in advance of beginning work. In addition we commit to the following specific quality control procedures for this project. • Full time process control tester onsite every day of earthwork, base course, pipe backfill, concrete placement, and asphalt paving operations on the project. • Provide test results to Weld County by 9am the following morning after tests are performed. • Cold weather concrete protection and heating in the winter months. We include maturity meters in every pour to monitor temperate and strength during the curing period. • Pre -pour checklists reviewed with Weld County inspectors before every concrete pour. • Earthwork and drainage checklists reviewed with Weld County inspectors daily. Kraemer North America, LLC Quality. Safety. Excellence 10 C PROJECT CONTROL • We included a proven concrete supplier in our price proposal that is familiar with Concrete Class D and Weld County specifications. We understand the no tolerance requirement on low strength concrete and therefore have avoided a low cost but unreliable supplier in our estimate. • Our schedule approach allows us to avoid major embankment fills and pipe trenches in the winter months and instead perform in the spring season to avoid issues with frozen ground. • Active Subcontractor Quality Management. We require pre activity meetings, daily reports, and checklist from all our subcontractors. One of Kaitlin's main responsibilities will be managing and enforcing quality requirements to our subcontractors. • Utilize GPS controlled earthwork equipment and a full time rover to ensure slopes and grades are correct. Kraemer self performs all surveying that will help expedite the as built process and ensure the quality of the survey books. • Dedicated personnel to collect load tickets and submit to the County at the end of the day. Stefan will work closely with Tyler, Kaitlin, and Weld County to ensure that quality processes are in place for all levels of work. This detailed activity review of requirements ensures quality is being planned into the project and consistency in our quality management approach.

Schedule 1 KRAEMER NORTH AMERICA Bridge 54-13A Replacement Project Schedule Introduction Utilizing our historical production data and experience in northern Colorado, Kraemer has prepared the following detailed project schedule. We have incorporated known constraints such as utility relocations, material procurement durations, and environmental requirements into the schedule to provide the County with a realistic approach to completing the work. The following summarizes our approach and includes a Gantt Chart with every salient feature and bid item included the appropriate phase. The keys to the delivery of a successful project include communication and a thorough plan derived by a team experienced with the type of work elements, location, and best practices the team has developed together from past projects. We have built a realistic, yet aggressive, schedule that capitalizes on the goals and objectives of delivering a quality project ahead of schedule. This schedule outlined, finishes the overall project well ahead of contractual dates, beats all milestone dates, and with effective communication and management we will open County Road 54 by July 1st, 2024, benefitting Weld County and its residents. • Start of WCR 54 Closure -January 12th, 2024 • in Water Work Complete -May 13th, 2024 • WCR 54 Open to Traffic -July 1st, 2024 Schedule Critical Elements Project Start Up - With our team just coming off our North I-25 Express Lanes Design -Build project they all know and understand the needs for a quick start- up. We will start the NTP deliverables as soon as notice of selection. With multiple Notice's to Proceed on the North I-25 Express Lanes project, the team knows and understands how to effectively manage, communicate, and deliver the required documents to achieve a successful start-up. Critical Winter Work - Using our historical data averaged over the last five years working in the area on the North I-25 Express Lanes project, we have built in an ample ammount of weather days from January till May, conservatively giving ourselves the ability to meet the schedule provided. This schedule is built around a 5 day work week, ensuring no work on the weekends. We also used our experience building bridges over the Big Thompson River and the Cache la Poudre River during the same winter months to collaborate develop an achievable schedule. Concurrent Structure Crews - We have the crews and equipment ready to start work on this project immediately. Our schedule is resource heavy through critical path elements which includes the bridge work. We have three structures crews working simultaneously to accelerate the bridge without sacrificing quality. Our controlling factor will be the Caisson Drill Rig, which will utilize one structure crew until all caissons have been complete. The other two structure crews will follow the caissons, forming abutments and pier columns, and once the caissons are complete, that crew will join on pier caps through the completion of the Superstructure. At this point, Kraemer will dedicate more crews to the project to be able to capitalize on concurrent work and place the deck within 4 weeks of girder erection. Winter Earthwork - With the bridge work driving the schedule, we have the float in our earthwork to eliminate the risk of frozen grade. Our earthwork crews will solely concentrate on excavation, riprap, and river grading when the project commences. This will allow them to complete the non -winter sensitive earthwork prior to starting any roadway embankment. Earthwork and drainage activities will start in the spring with more favorable weather and align with the completion of bridge approach work for a seamless transition into the paving season. Schedule Communication Communication is the cornerstone to a successful project, and we are committed to communicate across all facets of the project. We have developed many best practices to effectively communicate and collaborate on our plan, identify issues, and deliver our commitments for the project. With these tools and this approach, we are proactively engaging and collaborating with our client on multiple levels to deliver the highest quality project ahead of schedule. Short Interval Schedule - Communicating a plan as far out as possible and tracking progress is crucial to a successful project delivery. We plan, track, and update our Short Interval Schedule (lookahead) five weeks out, rather than the two or three weeks often required. This helps our team plan effectively, in more detail, on all upcoming activities. This communication tool also collaborates with Weld County to identify issues with ample time to make adjustments. Daily Testing & Inspection - Each day our team gathers and creates a schedule for the following days activities for all items requiring testing and inspection. This helps our own team as well as our client, sub -consultants, and sub- contractors prioritize and schedule their day. On dynamic projects, this best practice of communication creates a seamless operation. Monthly Updates - Utilizing the short interval schedule to as built, progress, and update. our monthly updates of the Baseline Schedule provide an accurate and well derived communication tool to look long range on our projects.

the Best Value Selection process outlined in Chapter 5, Article 5-4-40 of the Weld County Code Public Works has budgeted for this project in its 2024 budget Per the scoring criteria outlined for the Best Value Selection Process, Kraemer NA ranked the highest which represents the best value to the County The departments recommend awarding the contract to Kraemer NA in an amount not to exceed $11,533,491 78 Per the bid documents, construction is anticipated to start on January 3, 2024 and completed by no later than August 30, 2024 Kraemer NA, is proposing to complete the bridge and open the road to traffic by July 1 and to complete the project by July 30 I will plan on attending the BOCC meeting to answer questions that the Board may have Background Information On September 27, 2023, the BOCC approved a pass around allowing Public Works to use the Best Value bidding process The combined Request for Qualifications and Request for Proposals (RFQ/RFP) for the BR54/13A Bridge Replacement Project was advertised on October 4, 2023 in the Greeley Tribune and on BidNet Direct Four responses to the RFQ/RFP were received on November 1, 2023 and were presented to the BOCC on November 6, 2023 In accordance with Chapter 5, Article 5-4-40 of the Weld County Code, Public Works and Purchasing reviewed the RFQ/RFP responses and shortlisted 2 of the 4 bidders The shortlisted bidders (Kraemer NA and Ames Construction) were invited to an interview on November 15, 2023 to present their qualifications, approach to the project, and to answer project related questions the reviewing committee had on the proposals During the selection process, the submitted proposals were reviewed for errors and completeness Two of the bidders had small mathematical errors (less than $0 50) The engineer's estimate for the project was $11,292,145 07 RL Wadsworth's proposal was the lowest bid at $10,081,553 91 but they failed to account for all of the project schedule constraints Ames Construction's proposal was $10,960,400 00 and was a complete proposal Structures Inc 's proposal was $10,974,543 50 and was a complete proposal Kraemer NA's proposal was $11,533,491 78 and was a complete proposal The bid tabulation and sconng results are included with this document After reviewing all of the proposals, the selection process showed the best value to the County was Kraemer NA The reasons for Kraemer NA representing the best value to the County are a) Kraemer NA committed in their proposal to not overrun quantities that had been calculated and presented in the bid documents If quantities were overrun, Kraemer NA acknowledged that they were taking the risk and not getting paid for the overruns If quantities are underrun, the County keeps the savings represented by the underrun This represents a large risk that they are taking on and provides the County with assurances that the project will be completed on budget Ames and the other two contractors did not provide any such commitment in their proposals b) Kraemer NA committed to no contractor initiated change orders Only change orders initiated by the County would be considered for BOCC approval Ames and the other two contractors did not provide any such commitment in their proposals 2623 -MO F&) 003'1 17J18 c) Kraemer NA committed to drilling the caissons 3 feet deeper than required at no cost to the project The additional 3 feet of caisson provides a factor of safety for the bridge that helps ensure its foundations are more than adequate to support the bridge superstructure Ames and the other two contractors did not provide information showing they had considered providing deeper caissons in their proposal d),, Kraemer NA provided a list of items that would represent approximately $1 38 million cost savings to the project if the County chose to implement them Ames and the other two contractors did not provide any such list of savings to the project If the County were to implement all of the proposed cost savings ideas, the Kraemer NA cost for the project would drop to $10,151,763 78 which would be lower than the Ames Construction and Structure's Inc costs If all of the cost savings are implemented, Kraemer NA would be the low bidder by $808,636 22 e) Kraemer NA has a history of completing bridges on 1-25 ahead of schedule This history indicates they have the experience and resources to complete our bridge ahead of schedule Kraemer NA committed to having the bridge completed and the road open to the public by July 1, 2024 Kraemer NA's schedule shows the road will be open 60 days ahead of the completion date listed in the bid documents f) Kraemer NA shows the project will be complete by July 30, 2024 which is 30 days ahead of the completion date listed in the bid documents All of the work required to open the road to the public on July 1, 2024 would be complete The only work occurring between July 1 and July 30, 2024 would be off of the road with no road or lane closures occurring BOARD OF COUNTY COMMISSIONERS PASS -AROUND REVIEW PASS -AROUND TITLE BR54/13A Bridge Replacement Project — Contractor Selection Recommendation DEPARTMENT Public Works DATE November 16, 2023 PERSON REQUESTING Clay Kimmi, Don Dunker, Curtis Hall Brief description of the problem/issue Public Works has been conducting a best value selection process to select a contractor to build the BR54/13A Bridge Replacement project The process started with a combined request for qualifications and proposals (RFQ/RFP) where contractors submit a response showcasing their qualifications and their price for the project Four contractors (RL Wadsworth, Structures Inc , Ames Construction, and Kraemer NA) submitted proposals which were then reviewed by a team composed of staff from Public Works and Purchasing The review team then invited to two highest ranked contractors to an interview The RFQ/RFP proposals and interviews were scored and analyzed by the review team The review team was unanimous in their final rankings with Kraemer NA being ranked number one and Ames Construction as being ranked number two The table below shows the rankings, costs, and bnef comments for each contractor that submitted proposals for the project Contractor RFQIRFP Rank Interview Rank Cost Difference from Eng Est Comments Kraemer NA 1 1 $11 533,491 76 ' $241,346 71 (2 1 % high) • Committed to accelerated schedule — preliminary schedule shows opening the road in early July • Committed to not charging for material overruns and provided examples of ways to save money on the project • Committed to a very detailed Quality Control Program • Very capable of completing the project ahead of schedule and under budget Ames Construction 2 2 $10,960,400 00 X331,745 07 (3 0% low) • Preliminary schedule shows opening the road in early August • Has worked very well with the County on past projects • Quality oriented • Very capable of completing the project ahead of schedule and on budget Structures Inc 3 0 $10,974,543 50 -$317,601 77 (2 9% low) • Preliminary schedule shows opening the road in mid -August • Not as quality oriented as top two contractors • Would be able to

winter • Not as quality orients as top two contractors • Would be able to complete the project on schedule and on budget What options exist for the Board? Option 1 Approve the award of this project to Kraemer NA for an amount not to exceed $11,533,491 78 and al'ow Public Works to place the approval of the award on the agenda for the December 18, 7023 BOCC hearing Option 2 Request a work session to understand the team's justifications for recommending Kraemer NA Consequences: Delaying the award of the BR54/13A Bndge Replacement contract means meeting the schedule to get the bridge out of the water prior to spring runoff more difficult It also extends the amount of time the road will have to remain closed which could potentially impact the fall harvest in the areas surrounding the bridge Impacts: By awarding the contract to Kraemer NA, the contract would be going to the firm with the highest overall price However, the Best Value Process takes the contractor's qualifications and other factors into account The review team felt that Kraemer NA represented the best value to the County because they were proposing to open the road early which minimizes the impact to the traveling public Kraemer NA was the only contractor to commit to not overrunning the bid quantities They were the only contractor to identify areas of potential cost savings on the project Kraemer NA was also the only contractor who showed that they had accounted for the various project nsks in their bid and they presented a very strong commitment to producing a high quality project The better the quality of the project, the less long-term maintenance that is required by the County Less long-term maintenance represents a lower cost and a lower impact to the citizens of Weld County Costs (Current Fiscal Year / Ongoing or Subsequent Fiscal Years): The 2024 budget for Public Works accounts for the project costs The 2024 budget will not have to be adjusted to accommodate this project Recommendation Public Works recommends awarding the project to Kraemer NA in an amount not to exceed $11,533,491 78 Support Recommendation Schedule Place on BOCC Agenda Work Session Other/Comments Perry L Buck, Pro-Tem Mike Freeman, Chair Scott K.
