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.

The items highlighted in light blue above are required to be submitted and approved prior to the start of construction. 2. The items in the table above are not all inclusive. There may be additional submittals required by the Engineer. Subsection 105.03, paragraph 5 shall be deleted and replaced with the following: When the Engineer or Inspector finds the materials furnished, work performed, or the finished product are not in conformity with the Contract Documents, and Weld County determines, in its sole discretion, that it has resulted in an inferior or unsatisfactory product, the Work or Materials shall be removed and replaced or otherwise corrected by and at the expense of the Contractor. Subsection 105.03, paragraph 7 shall be deleted and replaced with the following: Materials will be sampled and tested by the Contractor per the sampling and testing schedules and procedures contained in the Contract Documents and in CDOT's Field Materials Manual. The quantity represented by five consecutive random samples will constitute a lot whenever production schedules and material continuity permit. The Engineer may establish a lot consisting of the quantity represented by any number of consecutive random samples from one to seven inclusive when it is necessary to represent short production runs, significant Material changes, or other unusual characteristics of the Work. Tests that are determined to have sampling or testing errors will not be used. The Contractor will not have the option of accepting a price reduction in lieu of producing material that complies with the Contract Documents. Continued production of nonconforming Material will not be permitted. Material, which is obviously defective, may be isolated and rejected by Weld County without regard to sampling sequence or location within a lot. Rejected material shall be removed at the Contractor's expense. Subsection 105.03 the two paragraphs following the Table 105-2 and starting with "If Pis a negative number ..." shall be deleted and replaced as follows: If P is a negative number quantity, the material will be accepted as being in conformity. In cases where one or more elements show a positive P value, such positive values will be added and the resulting sum will be used to determine the total P value. If the total P value is between 0 (zero) and 25, the Engineer may require correction or may accept the material at a reduced price. If P is greater than 25, the Engineer may: (1) require complete removal and replacement with specification material at no additional cost to the Department; (2) require corrective action to bring the material into conformity at no additional cost to the Department; or (3) where the finished product is found to be capable of performing the intended purpose and the value of the finished product is not affected, permit the Contractor to leave the material in place with an appropriate price reduction to be based on engineering evaluation but not to be less than that which have occurred had a reduction been made where P=25. If the P for aggregate gradation for items 206, 304, or the gradation of hydrated lime for item 403 is 0 (zero) or greater the reduction will apply to the contract price multiplied by the Multipliers (M) listed in the following table: PSP 22 WCR 76 AND WCR 35 IRRIGATION PROJECT November 8, 2023 10 REVISION OF SECTION 105 CONTROL OF WORK Subsection 105113(c) shall be added and shall include the following: (c) Conformityto the contract of embankment construction shall be determined per the following: Process Control Plan.

All sampling frequencies shall follow Table 106-2 and Stratified Random Sampling Schedules. Subsection 105.06, prior to subsection 105.06(a) shall be revised to include the following: A minimum of 10 days prior to the start of concrete paving, the Contractor shall perform a pre -production batch test consisting of a minimum of 10 cubic yards of the approved mix design. The pre -production batch test shall be performed using the actual batch plant and the materials to be used during the concrete paving operation. A set of flexural strength beams and splitting tensile strength cylinders shall be taken and tested at 7 days to determine the 7 -day average flexural and splitting tensile strengths. The average 7 -day flexural strength will be compared with the average 7 -day flexural strength from the laboratory tests for the approved mix design. If the average 7 -day flexural strength is more than 10% below the average 7 -day flexural strengths from the laboratory test for the approved mix design, the Contractor shall provide a written method statement detailing the corrective actions to be taken and if necessary what changes will be made to the approved mix design. The statement and mix design changes shall be approved by the Engineer. At the Engineer's discretion, another pre- production batch test may be required before actual production paving will be authorized to start If the Contractor fails to obtain approval for the method statement and mix design changes, the Engineer may issue a stop work PSP 24 WCR 76 AND WCR 35 IRRIGATION PROJECT November 8, 2023 12 REVISION OF SECTION 105 CONTROL OF WORK order shutting down paving production. Contract time will continue and no additional time will be added to the Project Schedule. Liquated damages will be assessed if the project is not completed on time. If at any time during production, the average 7 -day flexural strength for a lot or sublot is more than 10% below the average 7 -day flexural strength from the laboratory tests for the approved mix design, the Contractor shall immediately stop the concrete paving production and provide a written method statement detailing the corrective actions to be take® and if necessary what changes will be made to the approved mix design. The method statement and mix design changes shall be approved by the Engineer. At the Engineer's discretion, another pre -production batch test may be required before actual production paving will be authorized to start. If the Contractor fails to obtain approval for the method statement and mix design changes, the Engineer may issue a stop work order shutting down paving production. Contract time will continue and no additional time will be added to the Project Schedule. Liquated damages will be assessed if the project is not completed on time. Production will remain suspended until the source of the problem is identified and corrected. Each time production is suspended, connective actions shall be proposed in writing by the Contractor and approved in writing by the Engineer before production may resume. Subsection 105.16(a), paragraph 1 shall be deleted and replaced with the following: (a) Incentive/Dsincentive payments will not be made to the Contractor for Portland Cement Concrete Paving. The Pay Factors (PF) and Quality Levels(QL) will be made based on test results for the elements of compressive strength and pavement thickness (compressive strength criteria) or the elements of flexural strength anc pavement thickness (flexural strength criteria). The Department will indicate in the plans whether compressive strength or flexural strength criteria will be used. If the acceptance criteria are not indicated, flexural strength criteria shall be used. Subsection 105.06(b) shall delete the reference to Tables 105-4 or 105-5 and replace with Tables 105-10 or 105-11. Subsection 105.06(d) shall be deleted and replaced with the following: (d) As acceptance test results become available, they will be used to calculate accumulated QL for each element and for the ifeem.

Numbers from the calculations shall be carded to significant figures and rounded according to AASHTO Standard Recommended Practice R-11, Rounding Method. Incentive/Disincentive payments will not be made to the Contractor for Portland Cement Concrete Paving. The conformance to contract of the material and elements involved shall be evaluated per Section 412. Subsection 105.06(f) shall be deleted and replaced with the following: (f) When compressive strength is indicated, the Contractor may take cores at his own expense and per Colorado Procedure 55 to provide an alternative determination of strength to replace acceptance test results with a compressive strength less than 4,500 psi. The higher value of the 28 -day compressive strength of acceptance cylinders or fie corresponding core's compressive strength will be used for I/DP. When flexural strength is indicated in the Contract, the Contractor shall, in the presence of the Engineer, develop a correlation curve during the laboratory mix design process and during the first week of concrete placement per AASHTO T198 (ASTM C496) Splitting Tensile Strength of Cylindrical Concrete Specimens. Specimens shall be evaluated per CP65-19 method B. At least three splitting tensile strength specimens and four flexural strength specimens will be tested at 3, 7, 14, and 28 days. The splitting tensile strength and PSP 25 WCR 76 AND WCR 35 IRRIGATION PROJECT November 8, 2023 13 REVISION OF SECTION 105 CONTROL OF WORK flexural strength specimens for each age used to develop the correlation curve shall be cast from the same batch of concrete being placed on the project. The Lower Tolerance Limit (TL) for flexural strength shall be 600 psi. At any time during production, the Engineer may request a verification of the correlation curve developed during the patch testing for concrete paving. Verification of the curve shall be done by casting three splitting tensile specimens by the Department and testing them at the Contractor's Process Control Laboratory. The flexural strength of the correlated splitting tensile samples shall be compared to the Contractor PC flexural strength results cast from the same batch. For verification, both flexural strength specimens and splitting tensile specimens will be tested at 28 days. If the correlated flexural strength of the splitting tensile sample is not within 50 psi of the verification beam specimen's flexural strength, a new correlation curve shall be developed within 3 days for future low strength evaluations. The new correlation curve will be used for any future low flexural strength evaluations that result from concrete placed on or after the date the new correlation curve specimens are cast.

At the Engineer's discretion, additional random in -place density tests may be taken in order to meet scheduled minimums, provided the applicable pavement layer is available for testing under safe conditions. Beginning with the new job mix formula, the quantity it will represent shall be estimated. A revised schedule of acceptance tests will be based on that estimate. 3 Not to be used for incentive or disincentive pay. Test according to CP-33 and report results from Form 106 or Form 565 on Form 6. 4 Verified per Contractor's PC Plan D. Quality Level Chart. The Quality Level (QL) for each element used to calculate incentive or disincentive in Table 106-2 and each required sieve size shall be plotted. The QL will be calculated per the procedure in CP 71 for Determining Quality Level (QL). The QL will be calculated on tests 1 through 3, then tests 1 through 4, then tests 1 through 5, then thereafter the last five consecutive test results. The tonnage of material represented by the last test result shall correspond to the QL. For in place density tests, only results after final compaction shall be shown. The chart shall be posted daily at a location convenient for viewing by the Engineer. 2. Elements Not Conforming to Process Control. The QL of each discrete group of five test results, beginning with the first group of five test results, shall be a standard for evaluating material not conforming to process control. When the group QL is below 65, the process shall be considered as not conforming to the PCP. In this case, the Contractor shall take immediate action to bring the process back into control. Except where the cause of the problem is readily apparent and corrected without delay, production shall be suspended until the source of the problem is determined and corrected. A written explanation of actions taken to correct control problems shall accompany the test data and be submitted to the Engineer on the day the actions are taken.

The material for process control testing shall be sampled by the Contractor using approved procedures. Acceptable procedures are Colorado Procedures, AASHTO, and ASTM. The order of precedence is Colorado Procedures, AASHTO procedures, and then ASTM procedures. The location where material samples will be taken shall be indicated in the PCP. 4. Testing Standards. Acceptable procedures are Colorado Procedures, AASHTO, and ASTM. The order of precedence is Colorado Procedures, AASHTO procedures, and then ASTM procedures. 5. Testing Supervisor Qualifications. The person responsible for the process control sampling and testing shall be identified in the PCP and be qualified according to the requirements of CP 10. 6. Techmician Qualifications. Technicians taking samples and performing tests must be qualified according to the requirements of CP 10. 7. \ Testing Equipment. All of the testing equipment used to conduct process control testing shall conform to the standards specified in the test procedures and be in good working order. Nuclear testing devices used for process control testing of in -place density do not have to be calibrated on the Department's calibration blocks. 8. Reporting and Record Keeping. The Contractor shall report the results of the process control tests to the Engineer in writing at least once per day. The Contractor shall assemble a process control (PC) notebook and update it daily. This notebook shall contain all worksheets, test results forms, test results charts and quality level charts for each of the elements listed in Table 106-2. The Contractor shall submit the PC notebook to the Engineer for review once a month on the date agreed to at the Pre- Pavirrg 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, inducing 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. The maximum quantity of material represented by each test result, the elements, the frequency of testing and the minimue number of test results will be per Table 106-2. The location or time of sampling will be based on the stratified random procedure as described in CP 75. Acceptance sampling and testing procedures will be per the Schedule for Minimum Materials Sampling, Testing and Inspection in the CDOT Field Materials PSP 39 WCR 76 AND WCR 35 IRRIGATION PROJECT November 8, 2023 9 REVISION OF SECTION 106 CONTROL OF MATERIAL Manual. Samples for project acceptance testing shall be taken by the Contractor per the designated method. The samples shall be taken in the presence of the Engineer. Where appropriate, the Contractor shall reduce each sample to the size designated by the Engineer. The Contractor may retain a split of each sample which cannot be included as part of the Contractor's process control testing. If the Contractor elects to question the Hot Mix Asphalt (HMA) acceptance test results, the steps outlined in CP 17 shall be followed. Dispute of the acceptance test results per CP-17 will not be allowed unless the CP-13 Check Test Program has been successfully completed. The Contractor shall initiate, coordinate, and complete a successful Check Testing Program with the OA tester before HMA placement. The results from the CP 17 resolution process shall be binding on both the Department and the Contractor. Requests for CP 17 process for all elements except density shall be submitted in wilting to the Engineer within five workdays from the date the Contractor receives acceptance test data from the Engineer. The specific element questioned shall be identified in writing. All requests for the CP 17 process for the density element shall be submitted in writing to the Engineer within 24 hours of receiving test data from the Engineer. The Contractor shall choose a consultant laboratory not associated with the project from the CDOT pre- established list to perform the third party testing. The Contractor shall document his choice in writing at the Pre -Paving Conference. The Department shall determine that the consultant has no conflict of interest. If third party testing is required, the responsibility for the testing expenses shall be assigned per CP 17. The costs for testing are shown in CP 17, Table 17-2. All materials being used are subject to inspection and testing at any time before, during, or after incorporation into work. Acceptance tests will be made by and at the expense of the Department except when otherwise provided. (c) Check Testing Program (CTP). Before, or in conjunction with, placing the first 500 tons of asphalt pavement, under the direction of the Engineer, a CTP will be conducted between acceptance testing and process control testing programs. The CTP will consist of testing for asphalt content, theoretical maximum specific gravity, HMA 4.75 mm (#4) sieve, HMA 2.36 mm (#8) sieve, HMA 0.075 mm (#200) sieve, in -place density, and joint density per CP 13. 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. PSP 40 WCR 76 AND WCR 35 IRRIGATION PROJECT November 8, 2023 10 REVISION OF SECTION 106 CONTROL OF MATERIAL (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 bye no tolerance limit. 2. Quality Level. Calculate a QL for stability. If the QL for stability is less than 65, then production shall be halted, and the Contractor shall submit a written proposal for a mix design revision to the Engineer. The Engineer shall give written approval to the proposed mix design revision before production continues. After a new or revised mix design is approved, three additional stability tests will be performed on asphalt produced with the new or revised mix design. The test frequency shall be one per day unless altered by the Engineer. If the stability QL is less than 65, then production shall be halted until a new mix design has been completed and approved using plant produced material or the Contractor shall submit a written proposal for a mix design revision to the Engineer. The Engineer shall give written approval to the proposed mix design revision before production continues. 3. New or Revised Mix Design. Whenever a new or revised mix design is used and production resumes, threeadditional 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. PSP 41 WCR 76 AND WCR 35 IRRIGATION PROJECT November 8, 2023 11 REVISION OF SECTION 106 CONTROL OF MATERIAL 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. If the QL for VMA or AC is less than 65 or the QL for the test element of air voids is less than 70, then production shall be halted until a new mix design has been completed per CP 52 or CP 54, a new Form 43 issued, and the Contractor demonstrates that he is capable of producing a mixture meeting the verification requirements per A or B below: A. The Contractor shall produce test material at a site other than a Weld County project. The Contractor shall notify the Engineer a minimum of 48 hours before the requested test. The location and time of the test are subject to the approval of the Engineer before placement. Three samples will be tested for volumetric properties. If the QL for VMA or AC is equal or greater than 65 and the QL for the element of air voids is equal or greater than 70, full production may resume or; B. The Contractor may construct a 500 ton test strip on the project. Three samples in the last 200 tons will be tested for volumetric properties. After construction of the test section, production shall be halted until the testing is complete and element QLs are calculated. If the QL for VMA or AC is equal or greater than 65 or the QL for the element of air voids is equal or greater than 70, full production may resume. If the QL for VMA or AC is less than 65 or the QL for the element of air voids is less than 70, the material shall be removed and replaced at no cost to the Department. The time count will continue, and any delay to the project will be considered to have been caused by the Contractor and will not be compensable. The costs associated with mix designs shall be solely at the Contractor's expense. If the Contractor fails to verify the new mix design per A or B, then production shall be halted until a new mix design has been completed per CP 52 or CP 54, a new Form 43 issued, and the Contractor demonstrates they are capable of producing a mixture meeting the verification requirements per A or B. 4. New or Revised Mix Design. Whenever a new or revised mix design is used and production resumes, three additional volumetric field verification tests shall be performed, and the test results evaluated per the above requirements. The test frequency shall be one per day unless altered by the Engineer. 5. Field Verification Process Complete. When the field verification process described above is complete and production continues, the sample frequency will revert back to a minimum of 1/10,000 tons. The Engineer has the discretion to conduct additional verification tests at any time. PSP 42 WCR 76 AND V1UR 35 IRRIGATION PROJECT November 8, 2023 12 REVISION OF SECTION 106 CONTROL OF MATERIAL (f) (g) 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 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) Concttion 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 1/0 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. Subsection 106.96 shall delete references to Table 106-2 and 106-3 and replace with Table 106-4 and 106-5.

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: 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 N -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 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 lest strip to the dimensions specified in the Contract or as directed by the Engineer. The test strip may be incorporated into the final embankment. The Contractor shall determine the moisture conditioning necessary to achieve compaction and shall determine the equipment and number of passes necessary to achieve adequate compaction. The Contractor shall use compression -type or vibratory rollers on granular materials and sheepsfoot rollers on cohesive soils. Adequate compaction shall be demonstrated by the absence of rutting, pumping, or deflection following a proof roll of the test strip using any piece of construction equipment that exerts a minimum 18 -kip per axle load. The proof roll will be observed and accepted by the Engineer. Once the test strip passes a proof roll, the Contractor may resume embankment construction using the same moisture conditioning and compaction methods that were used to construct the test strip. Placement, moisture conditioning, and compaction of every lift of soil embankment with greater than 30 percent retained on the 3/4 -inch sieve shall be observed by the Contractor's 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 Roling. 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. PSP 65 WCR 76 AND WCR 35 IRRIGATION PROJECT December 5, 2023 5 REVISION OF SECTION 203 EXCAVATION AND EMBANKMENT The subgrade shall be proof rolled after the required compaction has been obtained and the subgrade has been shaped to the required cross section. The proof roller shall be operated in a systematic manner so that a record may be readily kept of the area tested and the working time required for the testing. Areas that are observed to have soft spots in the subgrade, where deflection is not uniform or is excessive as determined by the Engineer, shall be ripped, scarified, dried or wetted as necessary, and recompacted to the requirements for density and moisture at the Contractor's expense. After replacement and re -compaction, these areas shall be proof rolled again and all failures again corrected at the Contractor's expense. The repair may involve muck excavation, geogrid reinforcement, replacement of excavated materials, or other methods as directed by the Engineer. After the subgrade has been stabilized, the Contractor shall perform proof rolling per subsection 203.08. Final proof rolling will take place a maximum of two days (48 hours) after all mechanical stabilization or unbound aggregate work has been completed, unless otherwise approved by the Engineer. Final proof rolling will take place a minimum of two days after all lime or other chemical stabilization work has been completed, unless otherwise approved by the Engineer. The finished surface shall be smooth and uniform conforming to the typical sections. Variation from the subgrade plan elevations shall not exceed 0.04 feet.

The Contractor shall take penetration measurements every 6 inches across a transect perpendicular to the direction of the tractor and spanning the width of the subgrade soil preparation. Depths of penetration shall confirm that a minimum of 12 inches can be achieved without reaching 300 psi on the rod penetrometer pressure gage (approximately 30 pounds of pressure on the T -handle). Existing subgrade shall be de -compacted to a depth of 14 inches. If multiple passes are needed, the subsequent passes shall be positioned so that the ripping equipment (subsoilers) from the previous pass are split by the subsequent pass. Following ripping, the Contractor shall remove all sticks, stones, debris, clods, and all other substances greater than 6 inches in diameter. The Contractor shall restrict motorized vehicle and foot traffic from passing over the ripped area since this would recompact the areas that received subgrade soil preparation. The first 4 feet from the edge of pavement shall be ripped to a depth of 6 inches. If the project is going to use aggregate base course or recycled asphalt as a shouldering technique, those areas will not require subgrade soil preparation. Depth of soil ripping for the subgrade soil preparation shall be checked with the rod penetrometer. The Contractor shall verify adequate de -compaction of the entire area to have topsoil placed using a rod penetrometer in the presence of the Engineer. Tests shall be performed at a minimum of ten random locations per each acre as selected by the Engineer. The Test shall verify that a depth of 12 inches of penetration into the soil can be achieved without reaching 300 psi on the rod penetrometer pressure gage (approximately 30 pounds of pressure on the T -handle). If this depth cannot be achieved for 80 percent of the penetrations, the Contractor shall re -rip the area at no additional cost to the Department. 207.06 Placement of Topsoil and Seeding Media. Topsoil and Seeding Media shall be hauled and placed at the locations disturbed and will be re -vegetated or as shown on the plans. The contractor shall place a minimum thickness of 6 inches and should only be handled when it is dry enough to work without damaging soil structure. Topsoil and Seeding Media shall be placed a minimum depth of twelve (12) inches when placed over riprap as required on the plans. No Topsoil or Seeding Media shall be placed below ordinary high water mark except as otherwise specified in bio-stabilization bank treatments. Salvaged topsoil placement deeper than 6 inches is allowed if additional approved material is on -site. Contractor shall place topsoil in a method that does not re -compact subgrade material using low ground -contact pressure equipment, or by excavators and/or backhoes operating adjacent to it. The final grade shall be free of all materials greater than 4 inches in diameter within the designed clear zone for the project. Equipment not required for revegetation work will not be permitted in the areas of placed topsoil. Soil amendments, seedbed preparation, and permanent stabilization mulching shall be accomplished within four working days of placing the topsoil on the de -compacted civil subgrades. If placed topsoil is not mulched with permanent stabilization mulch within four working days, the Contractor shall complete interim stabilization methods per subsection 208.04(e), at no additional cost to the Department. Time to perform the work may be extended for delays due to weather. METHOD OF MEASUREMENT PSP 75 WCR 76 AND WCR 35 IRRIGATION PROJECT November 8, 2023 6 REVISION OF SECTION 207 TOPSOIL 207.07.

GLH will need a power and water schedule to avoid conflict with other utility lines. A preconstruction meeting will greatly aid to completed this process. Federal, State and Local Procedures: GLH Construction has been in business for the past 27 years. We review all Federal, State and Local requirements and standards before bidding on a project. We send in all submittals to be authorized before ordering any materials. We schedule and attend all precon's and meetings, to ensure that all standards are met. All testing that is required is done and results are submitted to the appropriate persons. Quality Control: GLH has worked with most of the same subcontractors and suppliers for many years. All superintendents check out materials as they come on to the project, verify that materials meet all submittals, and have a strict policy that all materials need to be of the highest quality, or they are shipped back. GLH prides itself for ensuring that all work done by our employees and subcontractors is superior to all other infrastructure companies and subcontractors in the area. Judgements/Claims/Suits: GLH is involved in one suit at the time. We have been named as a defendant in claims for a job site that had insufficient/inaccurate soils testing done. GLH did everything correctly in installing water/sewer/storm sewer utilities. GLH followed the soils to best management practices. The soil testing company has claimed bankruptcy. We are waiting to see if this suit will continue to court. OSHA Violations: GLH received an excavation violation on January 14, 2022 Liquidated Damages: GLH has not received any Liquidated Damages in the past five years. Changes in Ownership: GLH was sold in 2020. The original owners are still members of this new entity. Location: GLH is located in Windsor, CO, Weld County. All project coordination can be easily managed considering the proximity of the project. Weld County Projects: GLH has completed numerous projects in Weld County and is extremely familiar with its standards. On the previous list of "Large Scale Heavy Civil Road/Bridge Jobs with Emphasis on Irrigation" the projects that were in Weld County have been marked with a red asterisk. Employees and Budget: GLH has a current total of 68 full-time employees and the annual operating budget is constantly being revised based on the number of projects and size of projects that are awarded each year. The budget for 2021 was 72 million and 2022 was 77 million, Companies Facilities and Equipment: GLH is located in Windsor, Colorado in an office building, shop and yard for all owned equipment. GLH does not lease any of its equipment. Currently we have a total of 136 units that consist of pickups, trailers, loaders, excavators, graders, rollers, scrapers, backhoe's, dozers, water tankers, and compactors. GLH also has its own fleet of mechanics and service trucks that can go to our sites to repair and maintain equipment. A list is attached as Attachment A.

All five of the commissioners approved the pass around to be placed on the Board's agenda for January 3, 2024 for their consideration. The Public Works and Purchasing Departments have reviewed the submitted proposal in accordance with 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. Being the only proposal received and per the scoring criteria outlined for the Best Value Selection Process, GLH Construction ranked the highest which represents the best value to the County. The departments recommend awarding the contract to GLH Construction in an amount not to exceed $314,019.96. Per the bid documents; construction is anticipated to start on January 17, 2024 and completed by no later than March 27, 2024. GLH Construction is proposing to complete the project by this date. I will plan on attending the BOCC meeting to answer questions that the Board may have. Background Information On October 4, 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 WCR 76 and WCR 35 Irrigation Project was advertised on November 8, 2023 in the Greeley Tribune and on BidNet Direct. One response to the RFQ/RFP was received on December 7, 2023 and was presented to the BOCC on December 13, 2023. The submitted proposal was reviewed for errors and completeness. GLH Construction's proposal had small mathematical errors ($0.38). GLH has provided an email indicating they will honor the prices as submitted. The engineer's estimate for the project was $354,922.00. They are proposing a cost less than the engineer's estimate by $40,902.04. The bid tabulation and scoring results are included with this document. 10Z3 0(0(6:1 E(-,601 BOARD OF COUNTY COMMISSIONERS PASS -AROUND REVIEW PASS -AROUND TITLE: WCR 76 and WCR 35 Irrigation Project — Contractor Selection Recommendation DEPARTMENT: Public Works DATE: December 18, 2023 PERSON REQUESTING Trace Anderson. Don Dunker, Curtis Hall Brief descri ;tion of the problem/issue. Public Works has been conducting a best value selection process to select a contractor to build the WCR 76 and WCR 35 Irr gation 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. Out of ten contractors that attended the mandatory pre -proposal meeting, one contractor (GLH Construction) submitted a proposal. The RFQ/RFP proposal was scored and analyzed by the review team composed of staff from Public Works and Purchasing. The review team was unanimous in their determination that GLH Construction is the best value to the County The table below shows the cost and brief comments for the sole contractor that submitted a proposal for the project. Contractor RFQ/RFP Cost Difference Comments Rank from En Est GLH Constructior 1 $314,019.96 -$40,902.04 (13.0 % low) • Company resources • Company control/stormwater to is complete personnel local and inspection includes this has project. adequate crew. erosion What options exist for the Board? Option 1: Approve the award of this project to GLH Construction for an amount not to exceed $314,019.96 and allow Public Works to place the approval of the award on the agenda for the January 3, 2024 B0CC hearing. Option 2 Re•luest a work session to understand the team's justifications for recommending GLH Construction. Consequenc?s: Delaying the award of the WCR 76 and WCR 35 Irrigation project contract means the WCR 76 roadway maintenance and improvements will be delayed until 2025. The IGA between Weld County and the Town of Eato-i identifying WCR 76 as a truck route would need to be amended to reflect delayed completion of the roadway zprovements. This IGA was previously amended in October of 2022 to extend completion of the improvementE from 2022 to 2024. Impacts: By awarding the contract to GLH Construction, the contract would be going to the sole firm that submitted a proposal. However, the Best Value process takes the contractor's qualifications, cost, and other factors into account. The review team felt that GLH Construction represents the best value to the County because they are available to complete the project on the anticipated timeline and reduce delays to subsequent County projeczs. They are also proposing a cost less than the engineer's estimate, have experience constructing large items in :he contract, and can complete the project prior to the 2024 planting season. Costs (Curreit 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 GLH Construction in an amount not to exceed $314,019.96.
