6.For any other condition or reason determined to be in the public interest.
105.02 Plans, Shop Drawings, Working Drawings, Other submittals, and Construction
Drawings .
a.Plans . The Contract plans will show lines, grades, typical cross sections of the roadway, location and design of all structures, and summary of items appearing on the proposal. Only general features will be shown for steel and prestressed concrete bridges.
b.Shop drawings , Working Drawings , and Other Submittals - General . All work shall be performed per the plans, reviewed shop drawings, working drawings, or other submittals. Specific requirements for the required shop drawings, working drawings, and other submittals for this project are contained in the specifications. The Contractor shall be responsible for the accuracy of all dimensions and quantities shown on the shop drawings, working drawings, and other submittals. The Contractor shall correlate all information in the Contract, in the submittals, and in all revisio ns at the project site to ensure that there are no conflicts and that the work can be constructed as shown. The Contractor shall be responsible for all information that pertains to the fabrication processes and methods of construction. Shop drawings, working drawings, and other submittals shall be delivered to the Engineer. The Contractor shall notify the Engineer, in writing, at the time of submittal of shop drawings, working drawings, and other submittals, of any information submitted that deviates from the requirements of the plans and specifications. In addition, specific notation of the deviations or changes from the plans and specifications shall be placed on the shop drawing, working drawing, or other submittal. The first sheet or page of each set of shop drawings, working drawings, and other submittals shall be stamped “Approved for Construction” and signed and electronically sealed by the Contractor. Submittals shall be made in complete packages, which will allow the Engineer to properly review them for general compliance with the Contract and to effectively evaluate the proposed methods of construction. The allowed time for review shall not begin until such submittals are complete. 105.02 105-2 The format of the shop drawings, working drawings, and other submittals shall be as follows:
1.Electronic shop drawings and working drawings are preferred.
2.All manually drafted shop drawings and working drawings shall be 34 inches long by 22 inches wide overall. There shall be a 2 -inch margin on the left side of the sheet and a 1/2-inch margin on the other three sides. A blank space, 6 inches long by 3 inches wide, shall be left available near the lower right -hand corner of shop drawings, for the Engineer’s rev iew stamp. Computer drafted 11 -inch by 17 -inch drawings may be submitted.
3.There shall be a title block in the lower right -hand corner of each sheet. The title block shall show the project number, structure number, the location of the structure, the contents of the sheet, designer/engineer, sheet number, and revision number.
4.Design notes, calculations, lists, reports, descriptions, catalog cuts, and other non - drawing submittals shall be submitted on 8 1/2-inch by 11 -inch sheets.
5.Unless otherwise specified, seven sets of shop drawings, and other submittals shall be submitted to the Engineer. One additional set of shop drawings shall be submitted for each railroad company.
6.Unless otherwise specified, two sets of working drawings shall be submitted to the Engineer.
7.The shop drawings, working drawings, other submittals and all revisions shall be signed and electronically sealed for the Contractor, by a professional engineer registered in the state of Colorado when required by the specifications. Submittals without the required signature and seal will not be accepted and will be returned to the Contractor without action. Table 105- 1 summarizes the minimum required submittals is included at the end of subsection 105.02. Table 105- 1 lists submittals in one location for information. The table clarifies the type of submittal and whether the Contractor’s Engineer must sign and electronically seal the submittal. Table 105 -1 may not be all inclusive. The Contractor shall provide all submittals required by the Contract, including those not listed in the table.
c.Shop Drawings . The Contractor shall provide shop drawings to adequately control the work. The Contractor shall submit shop drawings to the Engineer for formal review. The Engineer will review the shop drawings to evaluate that general conformance with the design concept and that general compliance with the information given in the plans and specifications has been achieved. The review does not extend to accuracy of dimensions, means, methods, techniques, sequences, schemes, procedures of construction, or to safety precautions. The review by the Engineer is not a complete check. Review of the shop drawings does not relieve the Contractor of the responsibility for the c orrectness of the shop drawings. All work done before the Engineer’s review of shop drawings shall be at the Contractor’s sole risk. The Engineer may request additional details and require the Contractor to make changes in the shop drawings that are necessary to conform to the provisions and intent of the plans and specifications without additional cost to the Department. 105.02 105-3 After review, the Engineer will return two sets of shop drawings, for use by the Contractor and the Fabricator or Supplier. Returned shop drawings will be stamped with the Engineer’s review stamp to indicate one of the following: STATUS OF RETURNED SHOP DRAWINGS AND MEANINGS Reviewed, no exception taken Shop drawings have been reviewed and do not require additional review. Reviewed, revise as noted Shop drawings have been reviewed and the Contractor shall incorporate the comments noted in the shop drawings into the work. The shop drawings do not require additional review . Resubmit, revise as noted Shop drawings require correction or redrawing and shall be resubmitted for review. If shop drawings are returned for correction or redrawing, corrections shall be made, and the shop drawings shall be resubmitted by the Contractor in the same manner as the first submittal. Specific notation shall be made on the shop drawing s to indicate the revisions. The time required for the Engineer’s review of each submittal will not exceed four weeks after a complete submittal of shop drawings is received by the Engineer. It is the intent of these specifications that no more than two submittals of shop drawings shall be required for any one particular item. If additional submittals are required by actions of the Contractor, resulting delays shall be the responsibility of the Contractor. If additional submittals are required by the Engineer’s actions or if shop drawing review is delayed by the Engineer, the Contractor may request an extension of time as provided in subsection 108.08. All revisions made to the shop drawings after the Engineer’s initial review process will require resubmittal.
d.Working Drawings . The Contractor shall supplement the plans with working drawings to detail the construction or to provide the Engineer with information on the proposed methods of construction. Unless otherwise specified, the Contractor shall submit two sets of working drawings to the Engineer for information only. These drawings will not be formally reviewed by the Engineer. The Contractor shall submit working drawings to the Engineer 10 days before the start of work. Working drawings will not be returned to the Contractor.
e.Other Submittals . Other submittals shall be prepared and submitted by the Contractor as defined for working drawings. Unless otherwise specified, two copies shall be submitted to the Engineer for information only. The plans or specifications will indicate which submitt als require formal review by the Engineer. One record set of all design work performed by the Contractor’s Engineer shall be submitted to the Project Engineer. 105.02 105-4 (f) Construction Drawings . The Contractor shall keep one set of plans, reviewed shop drawings, working drawings, and other submittals available on the project site at all times. This set shall be defined as the “construction drawings.” The Contractor shall note on these constru ction drawings all changes and deviations from the work shown on the plans, shop drawings, working drawings, and other submittals. The construction drawings shall be kept current as the work progresses and notations shall be made within seven days of the change or deviation. The first sheet or page of each set of construction drawings shall be stamped “As Constructed” and signed by the Contractor.

105.03 Conformity to the Contract. All work performed and all materials furnished shall
conform to the lines, grades, cross sections, dimensions, and material requirements, including tolerances, shown in the Contract. All hot mix asphalt (HMA) materials or work will be evaluated for conformity to the Contract per subsection 105.05 except HMA that is used for patching and temporary pavement. For those items of work where working tolerances are not specified, the Contractor shall perform the work in a manner consistent with reasonable and customary manufacturing and construction practices. When the Engineer finds that the materials furnished, the work performed, or the finished product does not conform with the Contract, but that reasonably acceptable work has been produced, the Engineer will determine the extent the work will be accepted and remain in place. If accepted the Engineer will (1) document the basis for acceptance by Contract Modification Order that will provide for an appropriate reduction in the Contract price for such work or materials not otherwise provided for in this subsect ion or (2) notify the Contractor in writing that the Contract unit price will be reduced per this subsection when P is 25 or less, or
3.in lieu of a price reduction, permit correction or replacement of the finished product provided the correction or replacement does not adversely affect the work. When the Engineer finds the materials furnished, work performed, or the finished product are not in conformity with the Contract and 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. If asphalt cement testing demonstrates that asphalt cement was acid modified or alkaline modified, the supplier will be automatically decertified. In addition, all material placed containing the acid modified or alkaline modified asphalt cement shall be removed and replaced with specification material at no cost to the Department. Materials will be sampled and tested by the Department per the sampling and testing schedules and procedures contained in the Department’s Field Materials Manual. The approximate maximum quantity represented by each sample will be as set forth in the schedules. An additional number of samples in relation to the quantity of material 105.03 105-8 represented may be selected and tested at the Engineer’s discretion. 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 determi ned to have sampling or testing errors will not be used. Materials or work will be evaluated for price reduction only when deviations from specifications occur on any of the several individual tests for the lot. The several individual test values will be averaged and the percent of price reduction for the lot will be determined by applicable formula. The formula in (1) and (2) below will be used only when the lot is represented by three to seven tests inclusive.
1.The formula, P = (Xn + aR – Tu)F, will be used if a maximum limit only is specified or when the average of the several test values is above the midpoint of the specification band or above the job -mix formula value.
2.The formula, P = (TL + aR – Xn)F, will be used if a minimum limit only is specified or when the average of the several test values is below the midpoint of the specification band or below the job -mix formula value.
3.When the lot is represented by fewer than three tests, the materials will be evaluated for price reduction by the following procedure: Lots represented by two tests will be divided into two separate lots represented by one test each, as determined by t he Engineer. Each lot that deviates from the specifications will be price reduced by one of the following formulas. When a maximum limit only is specified or the test value is above the maximum specified limit, the formula P = 0.76(To – Tu)F will be used. When a minimum limit only is specified or the test value is below the minimum specified limit, the formula P = 0.76(TL – To)F will be used. When a lot is represented by one test only, the materials will be evaluated for price reduction as described in this paragraph. Where: P is the percent of reduction in contract price, Xn is the average of the several test values from samples taken from the lot, with “n” indicating the number of values, a is a variable factor to be used in “n” changes according to the following: when n is 3, a = 0.45; n is 4, a = 0.38; n is 5, a = 0.33; n is 6, a = 0.30; and n is 7, a = 0.28. R is the difference between the highest and lowest values in the group of several test results from the lot, Tu is the upper or maximum tolerance limit permitted by the specifications, TL is the lower or minimum tolerance limit permitted by the specifications, and To is the test value of the test that deviates from the specifications, F is price reduction factor to be applied for each element as shown in the following table: 105.03 105-9 Table 105-2 PRICE REDUCTION FACTORS Element Factor “F” 100 percent size sieve 1 12.5 mm (1/2") sieve and larger 1 150 μm (No. 100) sieve to 9.5 mm (3/8") sieve inclusive (except 100 percent size sieve) 3 75 μm (No. 200) sieve 6 75μm (No. 200) sieve (cover coat material) 25 Liquid Limit 3 Plasticity Index 10 Asphalt penetration 1 Asphalt residue 3 Portland Cement Concrete Pavement Fine Aggregate Sand Equivalent 0.3 Hydrated Lime Gradation 0.3 Toughness, inch -pounds, minimum 0.8 Tenacity, inch -pounds, minimum 0.8 Elastic Recovery, 25 °C, percent minimum 1.25 Ductility, 4 °C (5cm/min) cm, minimum of RTFO Residue 1.25 If P is less than 3, or a negative 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 whether the material is in conformity. If the total P value is between 3 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 specificati on 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 would 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 3 or greater the reduction will apply to the contract price multiplied by the Multipliers (M) listed in the following table: 105.03 105-10 Table 105 -3 MULTIPLIER FOR PRICE REDUCTIONS FOR MISCELLANEOUS ITEMS Item Number -Name Element Multiplier (M) 206- Structural Backfill Gradation 0.60 304-Aggregate Base Course Gradation 0.60 403-Hot Mix Asphalt * Hydrated Lime Gradation 0.60 Table 105 -3 Notes: * The P value for hydrated lime shall be applied to the price of the HMA item when asphalt cement is not paid for separately. Lime gradation P values will not be combined with Pay Factors for other elements. Table 105 -4 MULTIPLIER FOR HMA PRICE REDUCTIONS Where Asphalt Cement is not paid for separately: Item Number -Name Element Multiplier (M) 403-Stone Matrix Asphalt Gradation, Asphalt Cement Content, or Compaction 0.60 403-Hot Mix Asphalt * Hydrated Lime Gradation 0.60 Table 105 -4 Notes: * The P value for hydrated lime shall be applied to the price of the HMA item. Lime gradation P values will not be combined with Pay Factors for other elements. The following equation shows how the Multiplier is used to determine the price reduction. Price reduction = (P/100) • Multiplier • Price per Unit • Quantity. If no multiplier is listed no adjustment to the computed P is required. This is equivalent to a multiplier of one. Price reduction for those elements that are not included in the Table of Price Reduction Factors will be determined by the Engineer. The Contractor will not have the option of accepting a price reduction in lieu of producing specification material. Continued production of non -specification material will not be permitted. Material that is obviously defective may be isolated and rejected without regard to sampling sequence or location within a lot.
a.Retroreflectivity of High Build Acrylic Waterborne Paint and Modified Epoxy Pavement Marking . Retroreflectivity of High Build Acrylic Waterborne Paint and Modified Epoxy Pavement Marking shall be tested as follows: 105.03 105-11 1. The Contractor shall take retroreflectivity readings on all high build acrylic waterborne paint and modified epoxy pavement marking lines for each day of roadway striping work completed on the project. A test section is defined as each continuous line type (lane lines, centerlines, edge lines, channelizing lines, and others) 500 feet in length at a location that is selected by the Engineer using a Random Number Generator, which will be the representation of the work that has been completed in a single day. The Contractor shall use a Contractor -furnished retroreflectometer conforming to American Society for Testing and Materials ( ASTM ) E1710 or American Association of State Highway and Transportation Officials ( AASHTO ) TP111. The retroreflector meter shall be calibrated, tested and operated per manufacturer recommendations. The Contractor shall take 10 retroreflectivity readings within the test section for each stripe. These 10 readings shall be taken approximately 40 feet apart and shall be averaged to determ ine the retroreflectivity of that test section of striping. In cases where striping is less than 500 feet long, 10 readings shall be taken in 10 equal intervals.
2.The calibration for the retroreflector meter shall be witnessed and verified by the Engineer every day, before the readings being taken. The retroreflectivity readings shall be taken in the presence of the Engineer no sooner than 3 days and no later than 21 days after the marking is tack free. All scheduled readings within this timeline or beyond resulting in a reduced reading or failure will be at the risk of the Contractor. Initial minimum retroreflectivity reading (mcd/m2/lux) in the representative test section of pavement marking paint shall be according to table 105-5 . The pay factor for High Build Acrylic Waterborne Paint and Modified Epoxy Pavement Marking that is allowed to remain in place at a reduced price, shall be according to the following table and shall be applied to the unit bid price for Item 627, High Build Acrylic Waterborne Paint and Modified Epoxy Pavement Marking, and applied to the work completed in the respective day. Table 105 -5 PRICE REDUCTIONS FOR RETROREFLECTIVITY Retroreflectivity Reading (R) in the representative test section ( mcd/m 2/lux) Color Modified Epoxy High Build Acrylic Waterborne Paint Pay Factor (%) White R > 350 R ≥ 300 100 White 300 ≤ R < 350 250 ≤ R < 300 75 White R < 300 R < 250 Remove and replace Yellow R > 200 R ≥ 150 100 Yellow 150 ≤ R < 200 100 ≤ R < 150 75 Yellow R < 150 R < 100 Remove and replace
3.Before taking retroreflectivity readings, the Contractor shall remove at the retroreflectivity reading locations any excess beads placed during marking application.
4.Retroreflectivity readings may be altered by chip seals, rumble strips, wet surfaces, ice treatment, snow conditions, or abnormal pavement conditions. If the Engineer determines that accurate reading cannot be taken within the specified timeline per the manufacturer’s recommendations, through no fault of the Contractor, the Engineer may waive the requirements for testing and pay reduction. 105.03 105-12 5. Any and all work, including traffic control required for retroreflectivity readings, shall be included in the cost of the unit bid price for Item 627.
b.Violation of Working Time Limitation . If there is a violation of the working time limitations for traffic control as set forth in the special provisions, a written notice to stop work will be imposed on the Contractor at the start of the next working day. Work shall not resume until the Contr actor assures the Engineer, in writing, that there will not be a reoccurrence of the working time violation. If more violations take place, the Engineer will notify the Contractor in writing that there will be a price reduction charge for each incident per this specification. This incident price reduction charge will be deducted from any money due the Contractor. This price reduction will not be considered a penalty but will be a price reduction for failure to perform traffic control in compliance with the Contract. An incident is any violation up to 30 minutes in duration. Each 30 minutes or increment thereof will be considered as an incident. A price reduction will be assessed for each successive or cumulative 30 -minute period in violation of the working time limita tions, as determined by the Engineer. The price reduction for each incident will increase at a progressive rate starting with $150 for the second incident and increasing to $1 ,200 for the fifth and subsequent incidents per the following schedule. A 15 -minu te grace period will be allowed at the beginning of the second incident on the project before the price reduction is applied. This 15 -minute grace period applies only to the second incident. The number of incident charges will be accumulative throughout the duration of the Contract. Table 105 -6 VIOLATION OF THE WORKING TIME LIMITATIONS PRICE REDUCTION SCHEDULE Incident Incident Rate Total Price Reduction First Notice to Stop Work ---- Second $150 $150 Third $300 $450 Fourth $600 $1,050 Fifth $1,200 $2,250 Sixth $1,200 $3,450 > Sixth $1,200 $4,650 105.04 105-13 105.04 Conformity to the Contract of Superpave Performance Graded Binders . Asphalt binders will be price reduced according to the following if the requirements of subsection
702.01 are not met:
TABLE 105-7 PERFORMANCE GRADED BINDER LIMITS Property Specification Compliance Limit for Price Reduction of 0% Rejection Limit, Price Reduction = 25% G*sin (delta) of RTFO Residue 2.20 Min 1.87 Min < 1.53 Slope (m -value) of the Creep Curve at Low Grade Temperature + 10° C. 0.300 Min 0.295 Min < 0.266 Stiffness of the PAV Residue at Low Grade Temperature + 10° C, (Mpa) 300 Max 311 Max >355 The price reduction will be 25 percent at the rejection limit. Between the compliance limit and the rejection limit, the price reduction will be calculated as follows: PR = 25 ● CL – test value CL – RL Where: PR = Price Reduction CL = Compliance Limit RL = Rejection Limit
a.The price reductions will be cumulative if more than one PG binder property specified in the Table of Performance Graded Binder Limits is out of specification, resulting in P (total). When binder is included in the contract unit price for HMA, the price reduction will be calculated as follows: Amount of Reduction = [P (total)] ● [(1/100) ● (Invoice Price for PG Binder)] When the binder is paid for separately, the total price reduction will be calculated as follows: Amount of Reduction = [P(total)] ● [(1/100) ● (Contract Unit Price for PG Binder)]
b.Price reductions based on the “F” factors in the Table of Price Reduction Factors described in subsection 105.03 will be in addition to the PG binder price reductions. Other binder requirements listed in the Table of Performance Graded Binder Limits but n ot price reduced in subsections 105.03 or 105.04 may be tested but will not be considered for price reduction calculations. However, the Contractor will not be allowed to continue to produce mix with out of specification PG binder. If two consecutive samples fail to meet all requirements 105.05 105-14 listed in the Table of Performance Graded Binder Limits, the Contractor shall take corrective action before being all owed to continue production of hot mix a sphalt. If proper corrective measures cannot be readily determined, the Engineer will suspend the use of such material until the Engineer can determine from laboratory tests that the Contractor can provide material that is in compliance with the Table of Performance Graded Binder Limits.
c.The Contractor will not have the option of accepting a price reduction in lieu of producing specification material. Continued production of non -specification material will not be permitted. Material that is obviously defective may be isolated and rejected without regard to sampling sequence or location within a lot.
105.05 Conformity to the Contract of Hot Mix Asphalt. Conformity to the Contract of all
Hot Mix Asphalt, Item 403, except Hot Mix Asphalt (Patching) and temporary pavement will be determined by tests and evaluations of elements that include asphalt content, gradation, in-place density, and joint density per the following: All work performed and all materials furnished shall conform to the lines, grades, cross sections, dimensions, and material requirements, including tolerances, shown in the Contract. When the Engineer finds the materials or work furnished, work performed, or the finished product are not in conformity with the Contract and has resulted in an inferior or unsatisfactory product, the work or material shall be removed and replaced or otherw ise corrected at the expense of the Contractor. Materials will be sampled randomly and tested by the Department per subsection 106.05 and with the applicable procedures contained in the Department’s Field Materials Manual. The approximate maximum quantity represented by each sample will be as set forth in subsection 106.05. Additional samples may be selected and test ed as set forth in subsection
106.05 at the Engineer’s discretion.
A process will consist of either a single test value or a series of values resulting from related tests of an element of the Contractor’s work and materials. An element is a material or workmanship property that can be tested and evaluated for quality lev el by the Department approved sampling, testing, and analytical procedures. All materials produced will be assigned to a process. A change in process is defined as a change that affects the element involved. For any element, with the exception of the joi nt density element, a process normally will include all produced materials associated with that element before a change in the job mix formula (Form 43). For joint density, a new process will be established for each new layer of pavement or for changes in joint construction. Density measurements taken within each compaction test section will be a separate proces s. The Engineer may separate a process in order to accommodate small quantities or unusual variations. Evaluation of materials for pay factors (PF) will be done using only the Department’s acceptance test results. Each process will have a PF computed per the requirements of this Section. Test results determined to have sampling or testing errors will not be used. Except for in -place density measurements taken within a compaction test section, any test result for the asphalt content, in -place density or joint density element greater than the distance 2 x V (see Table 105 -8) outside the tolerance limits will be designated as a separate process and the quantity it represents will be evaluated per subsection 105.05(a). An element pay factor less than zero shall be zero. The calculated PF will be used to determine 105.05 105-15 the Incentive/Disincentive Payment (I/DP) for the process per 105.05(e) Evaluation of Work. In the case of in -place density or joint density, the Contractor will be allowed to core the exact location (or immediately adjacent location for joint density) of a test result more than 2 times V outside the tolerance limit. The core must be taken and furnished to the Engineer within eight hours after notification by the Engineer of the test result. The result of this core will be used in lieu of the previous test result. Cores not taken within eight hours after notification by the Engineer will not be used in lieu of the test result. All costs associated with coring shall be at the Contractor’s expense.
a.Representing Small Quantities. When it is necessary to represent a process by only one or two test results, PF will be the average of PFs resulting from the following: If the test result is within the tolerance limits, then PF = 1.00 If the test result is above the maximum specified limit, then PF = 1.00 – [0.25(T O – T U)/V] If the test result is below the minimum specified limit, then PF = 1.00 – [0.25(T L – T O)/V] Where: PF = pay factor. V = V factor from Table 105 -8. T O = the individual test result. T U = upper specification limit. T L = lower specification limit. The calculated PF will be used to determine the I/DP for the process.
b.Determining Quality Level. Each process with three or more test results will be evaluated for a quality level (QL) per Colorado Procedure (CP) 71.
c.Gradation Element. Each specified sieve, with the exception of 100 percent passing sieves, will be evaluated for QL separately. The lowest calculated QL for a sieve will be designated as the QL for gradation element for the process.
d.Joint Density Element. Joint Density will be tested according to subsection 401.17.
e.Process Pay Factor. Using the calculated QL for the process, compute the PF as follows: The final number of random samples (Pn) in each process will determine the final pay factor. As test values are accumulated for each process, Pn will change accordingly. When the proce ss has been completed, the number of random samples it contains will determine the computation of PF, based on Table 105 -9 and formula (1) below. When Pn is from 3 to 9, or greater than 200, PF will be computed using the formulas designated in Table 105 -9. Where Pn is equal to or greater than 10 and less than 201, PF will be computed by Formula (1): Formula (1) ) () ( 2 2 23 22 2 1 3 2 2 1 Pn PnPn Pn PF PF PF PF PF PFPFX −−• +−+++= 105.05 105-16 Where, when referring to Table 105 -9: PF 1= PF determined at the next lowest Pn formula using process QL PF 2= PF determined using the Pn formula shown for the process QL PF 3= PF determined at the next highest Pn formula using process QL Pn 2= the lowest Pn in the spread of values listed for the process Pn formula Pn 3= the lowest Pn in the spread of values listed for the next highest Pn formula Pn x= the actual number of test values in the process When evaluating the item of Furnish Hot Mix Asphalt, the PF for the element of In -Place Density shall be 1.0. Regardless of QL, the maximum PF in relation to Pn is limited per Table 105-9. As test results become available, they will be used to calculate QL and PF numbers for each process. The process I/DPs will then be calculated and accumulated for each element and for the item. The test results and the accumulated calculations will be made available to the Contractor upon request. Numbers from the calculations will be carried to significant figures and rounded according to AASHTO Standard Recommended Practice R -11, Rounding Method.
f.Evaluation of Work. When the PF of a process is 0.75 or greater, the finished quantity of work represented by the process will be accepted at the appropriate pay factor. If the PF is less than 0.75, the Engineer may:
1.Require complete removal and replacement with specification material at the Contractor’s expense; or
2.Where the finished product is found to be capable of performing the intended purpose and the value of the finished product is not affected, permit the Contractor to leave the material in place. If the material is permitted to remain in place, the PF for the process will not be greater than 0.75. The Region Materials Engineer (RME) will be consulted before determining the material will be allowed to remain in place. The RME will also be consulted to assist in determining an appropriate pay factor. When condition red, as described in subsection 106.05(g), exists for any element, resolution and correction will be per Section 106.05(g) . Material that the Engineer determines is defective may be isolated and rejected without regard to sampling sequence or location within a process. If removal and replacement is required because the joint density PF for a process is below 0.75, the Contractor shall remove and replace the full lane width adjacent to and including at least 6 inches beyond the visible joint line for the entire length of joint representing the process. If the lane removed is adjacent to another joint, that joint shall also be removed to a point 6 inches beyond the visible joint line. When a single joint density core is more than 2V outside the tolerance limits, the removal and replacement limits shall be identified by coring the failing joint at 25 -foot intervals until two successive cores are found to be 1V or less below the minimum tolerance limit. If removal and replacement is required, the Contractor shall submit documentation identifying the process to be used to correct the area in question in writing. The process will be approved by the Engineer before commencing the corrective work. 105.05 105-17 Table 105 -8 “W” AND “V” FACTORS FOR VARIOUS ELEMENTS Hot Mix Asphalt Element V Factor W Factor 2.36 mm (No. 8) mesh and larger sieves 2.8 N/A 600 μm (No. 30) mesh sieve 1.8 N/A 75 μm (No. 200) mesh sieve 0.8 N/A Gradation N/A 15 Asphalt Content 0.2 25 In-place Density 1.1 45 Joint Density 1.6 15 Table 105 -9 FORMULAS FOR CALCULATING PF BASED ON Pn Pn When Pn as shown at left is 3 to 9, or greater than 200, use designated formula below to calculate Pay Factor, PF = ..., when Pn is 10 to 200, use formula (1) above: Maximum PF 3 0.31177 + 1.57878 (QL/100) - 0.84862 (QL/100) 2 1.025 4 0.27890 + 1.51471 (QL/100) - 0.73553 (QL/100) 2 1.030 5 0.25529 + 1.48268 (QL/100) - 0.67759 (QL/100) 2 1.030 6 0.19468 + 1.56729 (QL/100) - 0.70239 (QL/100) 2 1.035 7 0.16709 + 1.58245 (QL/100) - 0.68705 (QL/100) 2 1.035 8 0.16394 + 1.55070 (QL/100) - 0.65270 (QL/100) 2 1.040 9 0.11412 + 1.63532 (QL/100) - 0.68786 (QL/100) 2 1.040 10 to 11 0.15344 +1.50104 (QL/100) - 0.58896 (QL/100) 2 1.045 12 to 14 0.07278 + 1.64285 (QL/100) - 0.65033 (QL/100) 2 1.045 15 to 18 0.07826 + 1.55649 (QL/100) - 0.56616 (QL/100) 2 1.050 19 to 25 0.09907 + 1.43088 (QL/100) - 0.45550 (QL/100) 2 1.050 26 to 37 0.07373 + 1.41851 (QL/100) - 0.41777 (QL/100) 2 1.055 38 to 69 0.10586 + 1.26473 (QL/100) - 0.29660 (QL/100) 2 1.055 70 to 200 0.21611 + 0.86111 (QL/100) 1.060 > 201 0.15221 + 0.92171 (QL/100) 1.060 105.06 105-18 (g) Process I/DP Computation.

h.Element I/DP. The I/DP for an element shall be computed by accumulating the process I/DPs for that element.
i.I/DP for a Mix Design. The I/DP for a mix design shall be computed by accumulating the process I/DPs for the asphalt content, in -place density, and gradation elements for that mix design. The accumulated quantities of materials for each element must be the same at the end of I/ DP calculations for a mix design.
j.Project I/DP. The I/DP for the project shall be computed by accumulating the mix design I/DPs and the joint density I/DPs. The accumulated quantities of materials for each element must be the same at the end of I/DP calculations for the project.
105.06 Conformity to the Contract of Portland Cement Concrete Pavement. Conformity
to the Contract of all Portland Cement Concrete Pavement, Item 412, will be determined per the following: When the Engineer finds that the materials furnished, the work performed, or the finished product does not conform to the Contract, or the Pay Factor (PF) for an element’s process is less than 0.75 but that reasonably acceptable work has been produced, the Engineer will 105.06 105-19 determine the extent of the work that will be accepted and remain in place. The Engineer will use a Contract Modification Order to document the justification for allowing the work to remain in place and the price adjustment that will be applied. When the Engineer finds the materials furnished, work performed, or the finished product is not in conformity with the Contract, or the PF for an element’s process is less than 0.75 and has resulted in an inferior or unsatisfactory product, the work or material shall be removed and replaced or otherwise corrected by and at the expense of the Contractor. When the PF for any process is 0.75 or greater, the finished quantity of work represented by the process will be accepted at the calculated pay factor. Materials will be sampled and tested by the Contractor and the Department per subsection
106.06 and with procedures contained in the Department’s Field Materials Manual. The
approximate quantity represented by each sample will be as set forth in subsection 106.06, Tables 106 -2 and 106- 3. Additional samples may be selected and tes ted at the Engineer’s discretion.
a.Incentive and Disincentive Payments (I/DP ) will be made based on a statistical analysis that yields Pay Factors (PF) and Quality Levels (QL). The PF and QL will be made based on test results for the elements of compressive strength and pavement thickness (compressive strength criteria) or the el ements of flexural strength and 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. Incentive or Disincentive payment will not be made for thickness of concrete pavement furnished by the Contractor and placed by others. When compressive strength criteria are indicated, then the QL will be calculated for the elements of compressive strength and pavement thickness on a process basis. When flexural strength criteria are indicated, then the QL will be calculated for the elem ents of flexural strength and pavement thickness on a process basis. A process will consist of the test results from a series of random samples. Test results determined to have sampling or testing errors will not be used. All materials produced will be assigned to a process. Changes in mix design, design pavement thickness, or a break of more than 120 working days between placements will create a new process. The following is provided to clarify changes in processes for each element:
1.Construction of mainline pavement, including the shoulders if placed with the mainline, is a single process for the compressive or flexural strength element, when the mix design does not change and there is not a break of more than 120 days between placements.
2.Construction of mainline pavement, including the shoulders if placed with the mainline, is a single process for the thickness element, when the planned thickness does not change and there is not a break of more than 120 days between placements.
3.Construction of ramps , acceleration and deceleration lanes and shoulders placed separately are considered separate processes.
4.Changes in paving equipment, changes in placement method, changes in hauling equipment, adjustments to mix designs that do not require a new mix design, changes in weather conditions, and changes in production rate shall not create a new process in the strength or thickness elements. 105.06 105-20 The Contractor and Engineer will determine element processes and what distinguishes them as processes during the P re-pave meeting before concrete placement.
b.When it is necessary to represent material by one or two tests, each individual test shall have a PF computed per the following: If the value of the test is at or above the lower tolerance limit, then PF = 1.000. If the value of the test is below the lower tolerance limit, then: PF = 1.00 – [0.25(T L -T0)/V] where: PF = pay factor . V = V factor from Tables 105 -4 or 105- 5. T 0 = the individual test value. T L= lower tolerance limit.
c.The following procedures will be used to compute Incentive and Disincentive Payments (I/DP), quality levels (QL), and pay factors (PF) for processes represented by three or more tests:
1.Quality Level (QL) will be calculated according to CP -71.
2.Compute the PF for the process. When the process has been completed, the number of tests (Pn) it includes shall determine the formula to be used to compute the final pay factor per the following:
A.For pavement thickness: When 3 ≤ Pn ≤ 5 If QL ≥ 85, then PF = 1.00 + (QL - 85)0.001333 If QL < 85, then PF = 1.00 + (QL - 85)0.005208 When 6 ≤ Pn ≤ 9 If QL ≥ 90, then PF = 1.00 + (QL - 90)0.002000 If QL < 90, then PF = 1.00 + (QL - 90)0.005682 When 10 ≤ Pn ≤ 25 If QL ≥ 93, then PF = 1.00 + (QL - 93)0.002857 If QL < 93, then PF = 1.00 + (QL - 93)0.006098 When Pn ≥ 26 If QL ≥ 95, then PF = 1.00 + (QL - 95)0.004000 If QL < 95, then PF = 1.00 + (QL - 95)0.006757
B.For compressive strength and flexural strength : When 3 ≤ Pn ≤ 5 If QL ≥ 85, then PF = 1.00 + (QL - 85)0.002000 If QL < 85, then PF = 1.00 + (QL - 85)0.005208 105.06 105-21 When 6 ≤ Pn ≤ 9 If QL ≥ 90, then PF = 1.00 + (QL - 90)0.003000 If QL < 90, then PF = 1.00 + (QL - 90)0.005682 When 10 ≤ Pn ≤ 25 If QL ≥ 93, then PF = 1.00 + (QL - 93)0.004286 If QL < 93, then PF = 1.00 + (QL - 93)0.006098 When Pn ≥ 26 If QL ≥ 95, then PF = 1.00 + (QL - 95)0.006000 If QL < 95, then PF = 1.00 + (QL - 95)0.006757
3.Compute the I/DP for the process: I/DP = (PF -1)(QR)(UP) where: QR = Quantity Represented by the process. UP = Unit Price bid for the Item. The total I/DP for an element shall be computed by accumulating the individual I/DP for each process of that element.
d.As acceptance test results become available, they will be used to calculate accumulated QL and Incentive and Disincentive Payments (I/DP) for each element and for the item. The Contractor’s test results, and the accumulated calculations shall be made available to the Engineer upon request. The Engineer’s test results, and the calculations will be made available to the Contractor as early as reasonably practical. Numbers from the calculations shall be carried to significant figures and rounded according to AASHTO Standard Recommended Practice R -11, Rounding Method. I/DP will be made to the Contractor per subsection 412.24(a). During production, interim I/DP will be computed for information only. The Pn will change as production continues and test results accumulate. The Pn at the time and I/DP is computed shall determine the formula to be used.
e.The Contractor shall not have the option of accepting a price reduction or disincentive in lieu of producing specification material. Continued production of non -specification material will not be permitted. Material that is obviously defective may be isolated and rejected without regard to sampling sequence or location within a process.
f.When compressive strength is indicated, the Contractor may take cores at his own expense and per Colorado Procedure 65 to provide an alternative determination of strength to replace acceptance test results with a compressive strength less than 4,500 psi. The higher value of the 28- day compressive strength of acceptance cylinders or the corresponding core’s compressive strength will be used for I/DP. 105.06 105-22 When flexural strength is indicated in the Contract, the Contractor shall, in the presence of the Engineer, develop a correlation curve during the first week of concrete placement per AASHTO T198 (ASTM C496) Splitting Tensile Strength of Cylindrical Concrete Specimens. At least three splitting tensile strength specimens and four flexural strength specimens will be tested at 3, 7, 14, and 28 days. The splitting tensile strength and flexural strength specimens for each age used to develop the correlation curve shall be cast from the same batch of concrete being placed on the project. When flexural strength is indicated, the Contractor may take cores at his own expense and per Colorado Procedure 65 to provide an alternative determination of strength to replace PC/OA test results with a flexural strength less than 570 psi. The cores for the alternate flexural strength evaluation shall be obtained after 28 days, but before 45 days following placement. The higher value of the 28 -day flexural strength of PC/OA beams or the corresponding core’s flexural strength will be used for I/DP. At any time during production, the Engineer may request a verification of the correlation curve developed during the first week of production. Verification of the curve shall be done by casting three splitting tensile specimens by the Department and testing them at the Region or Central Lab. 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.

g.Sand Equivalence. The sand equivalence (SE) as determined by CP 37 will be considered acceptable when the running average of three consecutive tests is greater than 80 percent and no individual test result is less than 75 percent. When the running average of three consecutive SE tests falls below 80 percent or an individual SE test result falls below 75 percent, paving operations shall be suspended. The Contractor shall submit a written plan to correct the low SE test results to the Engineer for approval. The Contractor shall not continue paving operations until the Engineer approves the plan in writing and three SE test results from random samples in the stockpile are above 80 percent .
h.Pavement Surface Texture. The Contractor shall perform process control (PC) testing for the pavement surface texture depth per CP 77 Method B. All PC results for surface texture depth measurements shall be included in the Contractor’s QC notebook. The start of PC testing for texturing depth shall be completed within 24 hours after the first 500 linear feet of textured pavement is placed for each lane. Paving shall not proceed until results are accepted by the Engineer. Surface texture will be considered acceptable when the average texture depth (ATD) of the panel is greater than 0.05 inch. When the ATD is less than 0.05 inches, the Contractor shall determine the area represented by this test. The area shall be determined by taking additional tests at 15- foot intervals parallel to the centerline in each direction from the affected location until two consecutive tests are found to be within the specified limits. Any surface with unacceptable texturing exceeding 25 linear feet in any lane or shoulder greater than 8 feet wide shall be diamond ground full width of the lane. Upon the second unacceptable test result, the Contractor shall notify the Engineer , in writing, of the action taken to provide an acceptable surface texture. The Department will perform surface texture acceptance testing per CP 77 Method B. The Department will determine the panel locations where acceptance test measurements are to be taken. One stratified random acceptance test per 2,500 linear feet or fraction thereof in each lane and shoulder wider than 8 feet shall be taken with a minimum of one test per day when the Contractor is paving. When the Department locates areas of surface texture that do not meet the minimum ATD, the Contractor will be notified, and the Contractor shall identify the limits of the deficient texture depth. After the Engineer approves the limits, the Contractor shall correct the deficient surface texture by diamond grinding full lane width to provide an ATD greater than 0.05 inch a t no additional cost to the project. The Contractor shall correct surface texture deficiencies before pavement smoothness testing and pav ement thickness determinations. 105.07 105-24 105.07 Conformity to Roadway Smoothness Criteria . Roadway smoothness testing and corrective work shall be performed as described below. The pavement smoothness category shall be MRI Category II unless shown otherwise on the plans. At least two weeks before the Pre -paving Conference the Contractor may request a change to the pavement smoothness category based on the CDOT’s Design Bulletin guidelines for assigning pavement smoothness categories . The Contractor shall not assume a change will be granted and shall be prepared to build the pavement according to the assigned smoothness category. Once paving operations have been started, a change in pavement smoothness category will not be made.
a.Smoothness Process Control Testing.
1.The Contractor shall perform Smoothness Process Control (SPC) testing . The test results shall be submitted to the Engineer within 48 hours of completion. SPC test results shall show the Mean Roughness Index (MRI ) for each 0.10 mile. All traffic control costs associated with SPC testing will be paid for per Section 630. SPC testing shall be performed on the first 2,000 tons for the final layer of HMA or each day’s paving within 24 hours after the concrete has achieved sufficient strength for PCCP . SPC testing on SMA will be tested after the sheen has been worn off. The Contractor may continue paving at his own risk. The Contractor shall not perform the SQC testing until after the concrete has attained a compressive strength of 1,000 ps i if a lightweight profiler is used or 2,000 psi if a high -speed profiler is used. SPC testing shall be performed using the Contractor’s inertial profiler, pursuant to the methods described in subsection 105.07(b). The Contractor’s Inertial Profiler and Operator shall be certified according to CP 78. This link has a list of certified profilers and operators . Production shall be suspended if SPC testing indicates that corrective work is required per subsection 105.07(e). If the SPC data becomes available after production has started for the day, suspension will begin at the end of that production day for HMA. Production will remain suspended until the problem is identified and corrected. Each time production is suspended, corrective actions shall be proposed in writing by the Contractor. Production shall not resume until the proposed corrective actions have been accepted by the Engineer in writing . When production resumes, the Contractor shall profile the first 2,000 tons of HMA or each day’s paving within 24 hours after the concrete has achieved sufficient strength for PCCP . The conditions described above for suspension of work will apply.
2.The finished transverse and longitudinal surface elevation of the pavement shall be measured using a 10 -foot straightedge. Areas to be measured will be directed by the Engineer. The Contractor shall furnish an approved 10 -foot straightedge, depth gauge, and operator to aid the Engineer in testing the pavement surface. Areas showing high spots of more than 3/16 inch in 10 feet shall be marked and diamond ground until the high spot does not exceed 3/16 inch in 10 feet.
b.Initial Smoothness Acceptance Testing . The Contractor shall perform Smoothness Acceptance Testing (SA ) that will be used for acceptance and calculation of incentive adjustments. 105.07 105-25 The Contractor shall submit a Method for Handling Traffic (MHT ) to the Engineer for approval at least five days in advance of SA testing. The MHT shall detail the methods for traffic control that will allow for continuous non -stop profiling of each lane to be profiled at a minimum speed of 15 mph and for the placement of triggers. The Contractor shall provide the traffic control per the approved MHT. SA testing shall not be performed without traffic control using the approved MHT. All traffic control costs associated with SA testing will be paid for per Section 630. Pavement surfaces shall be tested and accepted for longitudinal smoothness as described.
1.Testing Procedure (General). The longitudinal surface smoothness of the final pavement surface shall be tested by the Contractor per CP 74 and using the Contractor’s inertial profiler (profiler). The Contractor’s Profiler and Operator shall be certified according to CP 78. This link has a list of certified profilers and operators . The profiler’s instrumentation shall be verified per CP 74 before measurements. The Contractor shall lay out a distance calibration site. The distance calibration site shall be located no more than 10 miles from the project limits. The distance calibration site shall be 1056.0 feet long and shall be on a relatively f lat, straight section of pavement as approved by the Engineer. The site shall have a speed limit equal to the project’s highest speed limit that allows for the profiler to operate uninterrupted. The limits of the site shall be clearly marked, and the distance shall be measured to an accuracy of +/ - 1 inch. The Contractor shall provide in writing the site location to the Engineer. The cost of the distance calibration site will not be measured and paid for separately but shall be included in the work. The entire length of each through lane , climbing lane and passing lane including bridge approaches, bridge decks and intersections from the beginning to the end of the project shall be profiled in their planned final configuration and direction. Shoulders with a width of 12 feet or greater, ramps, tapers , turn slots , acceleration lanes and deceleration lanes will be profiled, but will not be subject to incentive adjustments. Shoulders with a width of 12 feet or more, ramps, tapers, turn slots, acceleration lanes and deceleration lanes will be evaluated for MRI and shall require corrective work if a 0.10 mile or fraction thereof section exceeds an MRI greater than 100.0 in/mile. The profile of the entire length of a lane shall be taken at one time. However, a lane profile may be broken into sections to accommodate project phasing. At the Pre -paving Conference, the Contractor shall submit a plan for breaking the project profiling into phases for approval by the Engineer. Shoulders less than 12 feet in width and medians will not be profiled and will not be subject to incentive adjustments. Shoulders less than 12 feet in width and medians constructed as part of the project shall be measured per subsection 105.07(a). Pavement 25 feet outside of a traffic circle and traffic circles will not be profiled and will not be subject to incentive adjustments. Traffic circles shall be measured per subsection 105.07(a). A sufficient distance shall be deleted from the profile to allow the profiler to obtain the testing speed, plus a 300- foot distance to stop and start when required. The distance deleted from a profile shall be minimized by reducing testing speed as necessary. Incentive adjustments will not be made for this area. The final surface of these areas shall be tested per subsection 105.07(a). 105.07 105-26 The profile shall include transverse joints when pavement is placed on both sides of the joint. When pavement is placed on only one side of the joint, the profile shall start and stop at project paving limits. The section of pavement 25 feet outside the paving limits to 5 feet inside the paving limits will be evaluated per subsection 105.07(a). The profile of the area 25 feet each side of every railroad crossing , cattle guard , bus pad, manhole , gutter pan and intersection (where there is a planned breakpoint in the profile grade line in the direction of traffic) shall be deleted from the profile before the MRI is determined. Incentive adjustments will not be made for these areas. Areas deleted from the profile shall be tested per subsection 105.07(a). The profile of the area 25 feet each side of the bridge deck shall be deleted from the profile before the MRI is determined. Incentive adjustments will not be made for this area. When both pavement and a bridge or bridge pavement are being constructed on the project, areas deleted from the profile shall be tested per subsection 105.07(a). Corrective work required in these areas will not be measured and paid for separately but shall be included in the work. For all other projects, the profile of the area 25 feet each side of the bridge deck shall be deleted from the profile before the MRI is determined. If the Engineer determines that corrective work is required in this area, payment will be made per subsection 109.04. The Contractor shall notify the Engineer in writing and the Department by email at DOT_Profiles@state.co.us at least five working days in advance of his intention to perform SA testing . The Contractor shall profile the project within 14 days after the completion of paving operations. The Department will determine if Smoothness Verification Testing (SV) will be performed. If SV testing will be performed, it will be performed at the same time as the SA testing. The Engineer will witness the SA profiling. Within 24 hours after each profile is collected, the Contractor shall submit the data electronically along with an SA data submittal form to the Department at DOT_Profiles@state.co.us, and to the Engineer.
2.Smoothness Testing Procedures. The Contractor shall mark the profiling limits and excluded areas. The Engineer will verify that the Contractor's marks are located properly. The Contractor shall use traffic cones with reflective tape or reflective tape on the pavement at the beginning and end of each lane for triggering the start and stop locations on the profiler and at any other location, where portions of the profile are being excluded. These locations shall be marked with temporary paint so that the final SA testing uses the same triggering locations. The ambient temperature shall be at least 34 °F for the profiler to operate. The Contractor shall clear the lanes to be tested of all debris before profiling. Each lane shall be profiled at least once. Profiling shall be at a constant speed (+/ - 5 mph of the distance calibration speed) with a minimum speed of 15 mph and a maximum speed of 70 mph. Shoulders with a width of 12 feet or more, ramps, tapers, turn sl ots, acceleration lanes and deceleration lanes shall be profiled once . The profile shall be taken in the planned direction of travel. The left and right wheel paths shall be profiled simultaneously. 105.07 105-27 Triggers for the start of the profile, the end of the profile and the locations of each exclusion shall be collected during each run. The collected profiles shall be electronically submitted to the Department and Engineer to be analyzed using CP 74. The Departmen t will determine an MRI for each 0.1 -mile section or fraction thereof of completed pavement. Sections will terminate at the beginning of an exclusion and a new section starts at the end of exclusion. The MRI consists of the left and right wheel path's profile passed through th e International Roughness Index (IRI) filter. The IRI for the left and right wheel paths are averaged to determine MRI. The Contractor’s SA test results will be available within 10 working days of the completion of SA testing. The Engineer will give the Contractor a report that will include the lane profiled, the MRI in 0.1 -mile increments and a summary of areas requiring corrective work. The Engineer may determine that it is necessary for the Contractor to re -profile a lane. Areas requiring corrective work will be determined according to subsection 105.07(e). Sections less than 0.005 miles in length shall not be subject to corrective work as specified by Table 105 -14. Sections less than 0.005 miles in length shall be evaluated per subsection 105.07(a).
c.MRI Category IV. For MRI Category IV pavements, the following shall be used for acceptance: An MRI for each 0.1 -mile section shall be determined on the original pavement surface before beginning the work per subsection 105.07(b) without exclusions. An MRI for each 0.1 -mile section shall be determined on the pavement surface after the work is complete per subsection 105.07(b) without exclusions. The original and final profile lengths shall have a difference in the length of each lane less than 0.2 percent. When the profile length difference exceeds 0.2 percent, the final testing shall be repeated. When a 0.1 -mile section has a final MRI greater than 92.0 in/mile and the final MRI is greater than the MRI before performing the work, that 0.1 -mile section shall be corrected by a method approved in writing by the Engineer. Corrective work shall be such that the resulting final MRI is equal to or less than the initial MRI or 92.0 in/mile, whichever is greater. All costs associated with corrective work shall be at the Contractor’s expense, including but not limited to traffic control, additional hot mix asphalt, grinding and milling. When the Contractor fails to collect the profile of the original pavement surface before beginning the work, the final pavement surface will be evaluated for corrective work per the criteria for Category III pavement smoothness. Incentive adjustments for smoothness will not be made for Category IV. Pavements evaluated for Category IV that will be overlaid with a surface seal shall be evaluated for pavement smoothness before application of the surface seal (chip seal).
d.Acceptance and Incentive Adjustments. Acceptance and incentive adjustments for pavement smoothness will be made on a square yard basis per the following: 105.07 105-28 Incentive adjustments will be based on the MRI for each 0.1 -mile section or fraction thereof. Incentive adjustments for Pavement Smoothness will be made per Table 105 -12 or 105-13 . Incentive payments will not be made until all sections requiring corrective work have been corrected. Final acceptance and incentive adjustments for pavement smoothness will be made on a square yard basis based on the MRI for each 0.1 -mile section or fraction thereof from the Contractor’s initial SA testing . Those sections requiring corrective work indicated by the initial SA testing will be re- evaluated. However, incentives will not be earned in these areas, regardless of the final smoothness.

e.Corrective Work. The Department will analyze the SA testing for acceptance and indicate areas requiring corrective work per subsection 105.07(b). Corrective work shall be proposed in writing by the Contractor. Corrective work shall not be performed until approved in writing by the Engineer. The Contractor shall perform corrective work in the areas indicated by the SA testing. The criteria for determining if a 0.1 -mile section requires corrective work is specified in Table 105-12 or 105-13 . The criteria for determining if a section less than 0.10 miles in length and greater than 0.005 miles in length requires corrective work is specified in Table 105-14 . Corrective work shall consist of diamond grinding, an approved overlay, or removal and replacement. Corrective work shall conform to of one of the following conditions:
1.HMA Removal and Replacement. The pavement requiring corrective work shall be removed, full width of the lane and the full thickness of the layer per subsection 202.09. 105.07 105-30 The removal area shall begin and end with a transverse butt joint, which shall be constructed with a transverse saw cut perpendicular to centerline. Replacement material shall be placed in sufficient quantity, so the finished surface conforms to grade and smoothness requirements. Sections removed and replaced shall be at least 0.20 miles in length.
2.HMA Overlay . The overlay shall cover the full width of the pavement including shoulders. The area overlaid shall begin and end with a transverse butt joint, which shall be constructed with a transverse saw cut and asphalt removal. All material shall be approved hot bituminous mixtures that meet all contract requirements. The overlay shall be placed so that the finished surface conforms to grade and smoothness requirements. The overlay area shall be compacted to the specified density. The overlay thickness shall be equivalent to that of the final layer per the Contract. Sections overlaid shall be at least 0.20 miles in length.
3.Diamond Grinding . Grinding shall not reduce planned pavement thickness by more than 0.3 inches. Diamond grinding shall be the full width of a wheel path. The wheel path is from the stripe to the center of the lane. The grinding process shall produce a pavement surface that is tr ue to grade and uniform in appearance. The grooves shall be evenly spaced. Any ridges on the outside edge next to the shoulder, auxiliary, ramps or adjacent lanes greater than 3/16 -inch-high shall be feathered out to the satisfaction of the Engineer in a separate, feather pass operation. The pavement surface after grinding shall have no depressions or misalignment of slope in the longitudinal direction exceeding 1/8 inch in 12 feet when measured with a 12-foot straightedge placed parallel to the centerline. All areas of deviation shall be reground at no additional cost. The slurry and residue resulting from the grinding operation shall not be allowed to flow across lanes occupied by the traffic and shall be continuously removed during the grinding operation, leaving the pavement in a clean condition. The Contractor shall haul the grinding residue to an approved location at no additional cost. Cores shall be taken to verify that minimum pavement thicknesses have been maintained. A minimum of one core shall be taken every 100 cumulative feet or fraction thereof per lane of diamond grinding, as directed by the Engineer. Coring shall be at the Contractor’s expense. For HMA pavements, the entire ground area of the final pavement surface shall be covered with a Tack Coat conforming to Section 407 (CSS -1h at 0.1 gallons per square yard of diluted emulsion; the emulsion shall be diluted with water at the rate of 50 percent water and 50 percent emulsion) when grinding is complete after final SA testing is complete. When any grinding on concrete pavement occurs where a core for determining pavement thickness has been previously taken, another core shall be taken after the grinding has been completed and shall replace the original core in the calculation of pavement thickness incentive and disincentive. Joint sealant that has been damaged by grinding on concrete pavement shall be repaired or replaced at the Contractor’s expense per Standard Plan M -412-1 and subsection 412.18. 105-31 For PCCP, diamond ground surface texture will be considered acceptable when the average texture depth (ATD) of the panel is greater than 0.05 inch. The Contractor will perform surface texture testing per CP 77 Method B. Each area in a lane that required diamond grinding will be tested at least once. Areas in a lane with more than 500 continuous feet of grinding will be tested at a frequency of one test per 500 linear feet. Areas with deficient surface texture shall be diamond ground and r etested.
f.Final Smoothness Acceptance Testing. After the Contractor has completed the required corrective work, the Contractor shall retest the pavement per subsection 105.07(b). Final SA testing shall only be required on lanes with sections requiring corrective work. Final SA testing shall start and stop at the same locations as the Initial SA testing. If additional corrective work is required, the Contractor shall perform the corrective work an d perform additional Final SA Testing. Time count will be charged pursuant to contract requirements during the time period required for all Final SA Testing. Delays associated with additional Final SA Testing will be considered nonexcusable and noncompen sable. The Contractor shall notify the E ngineer and the Department by e mail at DOT_Profiles@state.co.us at least 5 working days in advance of his intention to perform final SA testing . The Department will determine if Smoothness Verification Testing (SV) will be performed. If SV testing will be performed, it will be performed at the same time as the SA testing. The Initial SA and Final SA profile lengths shall have a difference in the length of each lane less than 0.2 percent. When the profile length difference exceeds 0.2 percent, the Final SA testing shall be repeated.
g.Department Smoothness Verification Testing (SV). The Department may elect to perform smoothness verification testing using the Department’s inertial profiler, with the methods described in subsection 105.07(b). The Engineer will notify the Contractor of the Department's intention to perform SV testing. The Contractor shall coordinate with the Department and his profil er to schedule SA and SV to occur at the same time. The Department will randomly select scheduled Contractor Smoothness Acceptance Testing to verify. A minimum of 25 percent of each scheduled Contractor Smoothness Acceptance Testing by an individual profiler will be verified. The Engineer may also request verification for any Smoothness Acceptance Testing. The Contractor’s SA test results will be compared to the Department’s SV test results. The Contractor’s SA test results will be considered acceptable and will be used for incentive payment if the following criteria are met:
1.The difference in MRI for a 1/10- mile section is less than 6.1 inches/mile for a minimum of 90 percent of the 1/10- mile sections for each lane .
2.The difference in average MRI for each lane is less than 6.1 inches/mile.
3.The difference in the length of each lane is less than 0.2 percent. When the Contractor’s SA test results are not considered acceptable, the Department’s SV test results will be used for incentive payment and the Contractor’s profiler certification will be suspended and evaluated pursuant to CP 78. The Contractor shall sc hedule with the Department within 10 working days to perform this evaluation or the profiler will be required to be re -certified per CP 78. 105.08 105-32 105.08 Document Management and Professional Engineer and Professional Land Surveyor Electronic Seals.

105.10 Cooperation by Contractor . The Contractor shall give the work the constant attention
necessary to facilitate progress and shall cooperate with the Engineer , inspectors, and other contractors. The Contractor shall have on the project, at all times that work is being performed, a competent superintendent capable of reading and understanding the contract documents and experienced in the type of work being performed. The superintendent will receive instructions from the Engineer and shall be authorized to act for the Contractor on the project and to execute orders or directions of the Engineer without delay. The superintendent shall promptly supply, irrespective of the amount of work sublet, materials, equipment, tools, labor, and incidentals to complete the Contract. PROJECT FIRST PROGRAM. Project First is required on all projects with an Engineer’s Estimate of over one million dollars and is optional and highly recommended for all other projects. The Project First Program shall not take precedent over any other Contract requirement and shall only apply to contracts with the Department. The Project First Program is structured to draw on the strengths of the Contractor and the Department to identify and achieve mutual goals. Project First is a scalable program that supports effective and efficient contract performance and is performed with reciprocal cooperation. The goal is a project completed within budget, on schedule, and per the Contract. The Department Engineer and the Superintendent are the lead representatives to address the issues promptly and at the appropriate level. Executives f rom both organizations are encouraged to be active supporters and to visit with the Project Teams. The Project First Program includes the Project Team, consisting of the Department and the Contractor, developing tools to identify and manage project risks a nd facilitate communication. The tools are developed and updated for the project’s duration in formal Workshops and project meetings. Project First Workshops .
a.Workshop Facilitation. All costs related to Project First are incidental to the project except for the actual costs for the use of a workshop third -party facilitator. The cost for a workshop facilitator shall be agreed upon before engagement. The Project Team shall equally shar e the facilitation costs. Either the Department or the Contractor may contract directly with the third party.
b.Initial Workshop. The Project Team shall conduct an initial workshop before the Preconstruction Conference. The Engineer and the Superintendent shall jointly agree on the individuals to invite to the initial workshop. They shall invite the members from their respective teams. The Region Transportation Director or the Program Engineer, the Resident Engineer, the Engineer, and other project personnel shall attend the initial workshop. The Contractor owner, executive or a representative, the Superintendent , project supervision personnel, and key subcontractors shall attend the initial workshop. The Engineer and the Superintendent shall jointly determine if other stakeholders shall attend. At the initial workshop, the parties each will discuss their planned approach to the project and develop the Project First Tools. 105.10 105-34 (c) Follow -up and Closeout Workshops . Project Team shall conduct follow -up workshops at least once every two months, unless the Engineer and the Superintendent jointly determine the frequency of these meetings can be reduced, and one final closeout workshop. When there are open items on the Project Risk Assessment Tool, workshops shall continue during no-work periods. Workshops are not required during landscape establishment periods. The Project Team shall conduct the closeout workshop before Final Acceptan ce. The Resident Engineer, the Engineer, the Superintendent, and project supervision personnel shall attend the follow -up and Closeout Workshops. The Region Transportation Director or Program Engineer, the Contractor owner, executive, or representatives are no t required to attend the follow -up and closeout workshops. The subcontractors or stakeholders with open risk items and incomplete work, shall attend the follow -up and closeout workshops. The Engineer and the Superintendent shall jointly determine if other stakeholders shall attend. In the follow -up workshops the parties will update Risk Assessment Tool risks, including adding any new risks and closing completed risks. The parties shall resolve all remaining risks and document lessons learned before or by the closeout workshop. The Pr oject Team should also celebrate the project successes. Project First Tools .
a.Project Risk Assessment Tool . The Project Team shall develop and update a Project Risk Assessment Tool. This Tool shall support risk identification, analysis, response strategy, monitoring, and control. All parties shall use the Project Risk Assessment Tool to document and manage the project risks. A risk for the purpose of Project First is an unexpected known event or potential future event that may positively or negatively affect the project costs, schedule, scope, or relationship. The Project Team may mo dify the Project Risk Assessment Tool to suit the project.
b.Project First Escalation Ladder . Use the Escalation Ladder to escalate major or repeated performance concerns to the next person in the supervisory chain. The Escalation Ladder is a list that includes the name, title, and contact information of the individuals in the supervisory chain for the Contractor’s project organization and for the Department’s project organization. The Contractor and the Department shall keep the Escalation Ladder up to date. The Project Team shall use the Escalation Ladder when the following types of concerns occur: • Bad Faith: When an individual is knowingly or willingly dishonest, not fulfilling legal or contractual obligations, misleads others, enters into an agreement without the intention or means to fulfill it, or violates basic standards of honesty in dealing wi th others. • Administration Performance: When an individual is not responsive in administrative performance such as resolving requests for information, developing partial payments, submitting required documentation, delays in progressing issues, and in negotiations. When an individual is unable to or is not competent in performing construction administration duties. 105.10 105-35 • Defiance: When an individual disregards Contract requirements or the direction of the Engineer. • Professionalism: When an individual acts in an unprofessional manner, including disrespectful, vulgar, or aggressive behavior. Although these concerns may contribute to the issues described in subsection 105.22, they are different. Subsection 105.22 is the Contract escalation process for issues related to items in subsections 104.02, 104.03, 106.05, 106.06, 108.08(a), and 108.08(d ) for merit and quantum.
c.Project First Charter. The establishment of a Project First charter is optional. A Charter shall not change the legal relationship of the parties to the Contract nor act as a waiver of, nor supersede the terms of the Contract. If a Charter is developed, the Project Team shall d evelop the Charter jointly.
105.11 Cooperation with Utilities . The Department will notify all utility companies, pipe line
owners , or other parties affected, and have all necessary adjustments of the public or private utility fixtures, pipe lines, and other appurtenances within or adjacent to the limits of construction made as soon as practicable. Water lines , gas lines , wire lines , service connections , meter and valve boxes , light standards , cableways, signals, and all other utility facilities within the limits of the proposed construction are to be relocated or adjusted at the owner’s expense unless otherwise provided in the Contract. The Contractor shall cooperate with the utility owners in their removal and relocation operations , so that progress is expedited, duplication of work is minimized and service interruptions are avoided. Per C.R.S. 9 -1.5-103 et seq. (Excavation Requirements – Plans and Specifications), the Department will certify in the project plans and specifications which Quality Level (A-D) the depicted existing known utilities are, pursuant to the most recent version of the ASCE Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data (CI/ASCE 38- 02). The Contractor shall not be relieved of its responsibility to comply with the requirements set forth and shall not rely solely on the Department’s plans and specifications when completing its work with respect to existing buried utilities. The Contract will indicate those utility items that are to be relocated or adjusted by the utility owner or those to be relocated or adjusted by the Contractor. The Contractor shall consider in the bid proposal all of the permanent and temporary utility facilities in their present or relocated positions as shown in the Contract and as revealed by site investigation. Utility delays due to changes that are the responsibility of the Contractor will be considered nonexcusable delays. Utility delays beyond the Contractor’s control and not due to the fault or negligence of the Contractor shall be documented by the Contractor and tied to the project’s critica l path schedule, so as to demonstrate a timeline of events leading up to the utility owner’s failure to perform and subsequent delay to the project. Delays will be determined to be compensable or noncompensable per subsection 108.08. The Contractor and the Engineer shall meet with the utility owners as often as necessary to coordinate and schedule relocations or adjustments. Additional compensation will not be allowed for foreseeable coordination, inconvenience, or damage sustained due to interference from the utility facilities or the removal or relocation operations as indicated in the Contract. If utility facilities or appurtenances are found that are neither identified in the Contract, nor revealed by site investigation, the Engineer will determine whether adjustment or relocation of the utility is necessary. The Engineer will make arrangements with either the utility owner 105.12 105-36 or the Contractor to accomplish necessary adjustments or relocations when not otherwise provided for in the Contract. Extra work will be considered for payment per subsection
104.03 Consideration for delays shall be per subsection 108.08(d).
Where the Contractor’s operations are adjacent to properties of railroad, telegraph, telephone, power, or other utility companies, that damage might result in considerable expense, loss, or inconvenience, work shall not commence until arrangements for the protection of the utilities have been made. If water or utility services are interrupted, the Contractor shall promptly notify the owner and shall cooperate in the restoration of service.

Minor structures and retaining wall staking will be limited to stakes establishing line and grade by using offset line and grade stakes. Major structures staking and references will be limited to centerlines (or work lines or control lines) as shown on the plans, appropriate offset lines and grades; and elevations set for footings , piers, pier cap s, abutments , bottom of deck grades and finish deck screed grades. 105.14 105-37 It will be the responsibility of the Contractor to use these references and marks and establish any additional control and layout necessary for the proper completion of the work in its final location. The Contractor shall be responsible for the accuracy of all the vertical and horizontal control it transfers and establishes. The Contractor shall, when required, provide access to abutments, piers or other locations, and shall furnish working platforms that meet applicable safety requirements so the Engineer’s duties can be performed. The Contractor shall preserve all stakes and marks. If any stakes or marks are destroyed, disturbed or removed by the Contractor, subcontractors, or suppliers, the cost of replacing them will be charged against the Contractor and will be deducted from the payment for the work at a negotiated rate not to exceed $150 per hour. It is the responsibility of the Contractor to perform all required layout work, which shall include, but will not be limited to the following:
1.Piling locations and cut off elevation.
2.Girder seats on piers and abutments .
3.Bolt locations and patterns .
4.Construction sign locations.

105.14 Authority and Duties of the Project Engineer . The Project Engineer has immediate
charge of the administration and engineering details of each construction project. The Project Engineer has the authority to exercise all duties and responsibilities of the Engineer contained in the Contract, except those specifically retained by the Chief Engineer . The CDOT Project Engineer and the CDOT Resident Engineer are the only representatives of the Chief Engineer authorized to sign Contract Modification Orders. The Project Engineer is responsible for initial decisions relating to Contractor disputes pursuan t to subsection 105.22.
105.15 Duties of the Inspector . Inspectors employed by the Department are authorized to
inspect all work done, and materials furnished. This inspection may extend to all or any part of the work and to the preparation, fabrication or manufacture of the materials to be used. The inspector is not authorized to alter or waive the provisions of the Contract. The inspec tor is not authorized to issue instructions contrary to the provisions of the Contract or to act as foreman for the Contractor.
105.16 Inspection and Testing of Work . All materials and each part or detail of the work shall
be subject to inspection by the Engineer. The Engineer shall be allowed access to all parts of the work and shall be furnished with information and assistance by the Contractor as required to make a complete and detailed inspection. Before final acceptance of the work, the Contractor shall remove or uncover such portions of the finished work, as directed. After examination, by the Engineer, the Contractor shall restore the work to the standard required by the Contract. If the work thu s exposed or examined proves acceptable, the uncovering, removing, or restoring the work will be paid for as extra work. If the work exposed or examined proves unacceptable, the uncovering, removing, or restoring the work shall be at the Contractor’s expen se. 105.17 105-38 Any work done or materials used without inspection by an authorized Department representative may be ordered uncovered, removed, or restored at the Contractor’s expense. When any unit of government or political subdivision, utility , or railroad corporation is to pay a portion of the cost of the work covered by a highway Contract, its respective representatives shall have the right to inspect the work. This inspection shall not make any unit of government or political subdivision, utility, or railroad corporation a party to the Contract, and shall not interfere with the rights of either party. All inspections and all tests conducted by the Department are for the convenience and benefit of the Department. These inspections and tests do not constitute acceptance of the materials or work tested or inspected, and the Department may reject or accept any work or materials at any time before the inspection pursuant to subsection 105.21(b) whether or not previous inspections or tests were conducted by the Engineer or authorized representative.
105.17 Removal of Unacceptable Work and Unauthorized Work . Unacceptable work is
work that does not conform to the requirements of the Contract. Unacceptable work , resulting from any cause, found to exist before the final acceptance of the work, shall be removed and replaced in an acceptable manner at the Contractor’s expense. The fact that the Engineer or an inspector may have overlooked the unacceptable work shall not constitute an acceptance of any part of the work. Unauthorized work is work that was done without adequate lines and grades having been established by the Engineer or by the Contractor, work done contrary to the instructions of the Engineer, work done beyond the lines shown on the plans, or extra work done without the Engineer’s authorization. Unauthorized work will not be paid for under the provisions of the Contract and may be ordered removed or replaced at the Contractor’s expense. If the Contractor fails to comply with any order of the Engineer made under the provisions of this subsection, the Engineer will have authority to cause unacceptable work to be remedied or removed and replaced, and unauthorized work to be removed. The Engi neer will deduct the costs from any monies due or to become due the Contractor.
105.18 Load Restrictions . The Contractor shall comply with all legal load restrictions in the
hauling of equipment or materials on public roads beyond the limits of the project. A special permit will not relieve the Contractor of liability for damage resulting from the moving of equipment or material. The operation of equipment or hauling loads that cause damage to structures, the roadway or any other construction will not be permitted. Hauling of materials over the base course or surface course under construction shall be limited by the Contractor to methods and equipment that will prevent damage to the pavement structure. Loads will not be permitted on a concrete pavement or structure before the expiration of the curing period. The Contractor shall be responsible for the repair of all damage and relate d expense resulting from hauling equipment and construction operations. If a vehicle’s gross weight exceeds the legal limit, and the material transported by the vehicle is delivered to the project, the material and the scale ticket (certificate of correct weight) will not be accepted. 105.19 105-39 If a scale ticket from an overweight vehicle is inadvertently accepted and the material incorporated into the project, the Engineer will adjust the price for the overweight load as follows:
1.The pay item quantity represented by the amount of material in excess of the legal weight will not be paid for.
2.A price reduction will be assessed for the overweight portion of the load based on the following schedule. Overweight (Pounds) Price Reduction (Dollars) 0 - 3000 20 3001 - 4000 40 4001 - 5000 82 5001 - 6,000 130 6001 - 7000 226 7001 - 8000 376 8001 - 9000 582 9,001 - 10,000 842 Over 10,000 $870 plus $164 for each 1,000 lbs. over 10,000 lbs.
105.19 Maintenance During Construction . The Contractor shall maintain all work that is
included in the Contract during construction and until final written acceptance, except as otherwise specified in subsection 107.17. This maintenance shall constitute continuous and effective work prosecuted with adequate equipment and forces, so the roadway or structures are kept in satisfactory condition at all times. If the Contract involves the placement of material on or utilization of, a previously constructed subgrade , pavement structure or structure, the Contractor shall maintain the previously constructed work during all construction operations. All cost of maintaining the contract work during construction and before final written acceptance will not be paid for separately, but shall be included in the work, except as otherwise specified in subsection 107.17.
105.20 Failure to Maintain Roadway or Structure. If the Contractor fails to comply with the
provisions of subsection 105.19, the Engineer will immediately notify the Contractor of such noncompliance. Except in the case of traffic signal maintenance, the Contractor shall respond and remedy unsatisfactory maintenance within 24 hours after receipt of such notice. If the Contractor fails to remedy unsatisfactory maintenance in the allotted time, the Engineer may immediately proceed to maintain the project, and the entire cost of this maintenance will be deducted from the monies due or to become due to the Contractor on the Contract. In the case of traffic signal maintenance, the Contractor shall respond and remedy unsatisfactory maintenance within one hour of receipt of notice on urban highways, and within four hours of receipt of notice on rural highways. Traffic signal maintenance shall include all approved traffic control items and work that are required to maintain traffic through the affected area while the traffic signal is being repaired 105.21 105-40 or replaced. If the Department performs traffic signal maintenance, the Department shall be held harmless for all subsequent occurrences of maintenance to the signals that the Department maintained. If damage occurs to an existing structure through improper maintenance per 105.19, the Contractor shall submit a repair procedure to the Engineer to repair the defect(s). The repair categories and requirements are defined as follows:
a.“In-kind” repairs . In-kind repairs are repairs where the As- Built or Advertised plans are utilized to replace or repair damaged components with identical dimensions and materials used plans and where no plan modifications are made. In -kind repair procedures shall be reviewed and accepted by the Engineer before any repair. The use of approved repair grouts or doweled reinforcing with epoxy adhesive is permitted in in -kind repairs. Doweled reinforcing shall meet or exceed the strength requirements of the original design.
b.“Modified repairs ”. Modified repairs are those which deviate in dimensions and/or materials from the As- Built or Advertised plans or where plans are not available. Modified repair procedure submittals shall include calculations, independent design calculations, shop drawings, and/or working drawings per 105.02, and any other applicable section of the specifications for the needed repair. The Contractor’s Engineer shall electronically seal Modified repair submittals. Damage to new structures or modified structures, shall be repaired per the contract documents. The Engineer of Record shall be notified and review all corresponding submittals before any repairs.
105.21 Acceptance .
a.Partial Acceptance . If, during the prosecution of the project, the Contractor satisfactorily completes a unit or portion of the project, such as a structure, an interchange, or a section of road or pavement that can be used advantageously for traffic, the Engineer may make final inspection of that unit. If the Engineer finds that the unit has been satisfactorily completed in compliance with the Contract, the Contractor may be relieved of further responsibility for that unit except as otherwise provided in subsection 107.16. Partial acceptance shall not void or alter any of the terms of the Contract.
b.Final Acceptance . Upon notice from the Contractor of presumptive completion of the entire project, the Engineer will make an inspection. If the work provided for by the Contract has been satisfactorily completed, that inspection shall constitute the final inspection and t he Engineer will notify the Contractor in writing of final acceptance indicating the date the project was inspected and accepted. If the inspection discloses any unsatisfactory work, the Engineer will give the Contractor a written list of the work needing correction. Upon correction of the work, another inspection will be made. If the work has been satisfactorily completed, the Engin eer will notify the Contractor in writing of the date of final inspection and acceptance. Final acceptance under this subsection does not waive any legal rights contained in subsection 107.21. 105.22 105-41 If not included in the Partial or Final Acceptance letter, no later than 3 working days after the acceptance letter is provided to the Contractor, the Engineer will provide in writing a detailed list of all remaining documentation required by the Contract. Upon reviewing and accepting the remaining documentation, and with no other outstanding issue(s), the Engineer will release retainage as follows:
1.65% of the current retainage shall be released.
2.If the release of retainage is less than $10,000, no retainage will be released.
3.Retainage will be released only to the extent that the remaining retainage shall not be less than $20,000.
105.22 Dispute Resolution . Subsections 105.22, 105.23, and 105.24 detail the process through
which the parties (CDOT and the Contractor) agree to resolve any issue that may result in a dispute. The intent of the process is to resolve issues early, efficiently, and as close to the project level as possible. Figure 105 -1 outlines the process. Specified time frames may be extended by mutual agreement of the Engineer and the Contractor. In these subsections, when a time frame ends on a Saturday, Sunday or holiday, the time frame shall be extended to the next scheduled workday . An issue is a disagreement concerning contract price, time, interpretation of the Contract, or all three between the parties at the project level regarding or relating to the Contract. Issues include, but are not limited to, a disagreement resulting from a delay, a change order, another written order, or an oral order from the Project Engineer, including any direction, instruction, interpretation, or determination by the Project Engineer , interpretations of the Contract provisions, plans, or specifications or the existence of alleged differing site conditions. The Contractor shall bring all issue(s) to the Project Engineer’s attention, in writing, within 30 days of the Contractor being aware of the issue(s). Written notice must take the form of a stand -alone, non -chain e -mail or letter, addressed and delivered t o the Project Engineer. If a Contractor provides written notice outside of the 30 -day deadline, it shall be presumed that CDOT suffered prejudice. Where the Contractor failed to provide the required notice, the failure to provide notice may be treated as a separate and threshold dispute to be resolved before other related disputes(s) are submitted, addressed, or resolved. A dispute is an issue which the Contractor and CDOT have not been able to resolve and for which the Contractor submits a written formal notice of dispute per subsection 105.22(b). A claim is a dispute not resolved at the Resident Engineer level or resolved after a DRB recommendation. The term "merit" refers to the right of a party to recover on a claim or dispute, irrespective of quantum, based on the substance, elements, and grounds of that claim or dispute. The term "quantum" refers to the quantity or amount of compensation or time deserved when a claim or dispute is found to have merit. Disputes from subcontractors, material suppliers, or any other entity not party to the Contract shall be submitted through the Contractor. Review of a pass -through dispute does not create privity of Contract between CDOT and the subcontractor. An audit may be performed by the Department for any dispute or claim . All audits will be completed within 90 days of the request for an audit, provided the Contractor allows the auditors reasonable and timely access to the contractor’s books and records. If CDOT does not respond within the specified timelines, the Contractor may advance the dispute to the next level. 105.22 105-42 When the Project Engineer is a Consultant Project Engineer , actions, decisions, and determinations specified as made by the Project Engineer shall be made by the Resident Engineer. The dispute resolution process set forth in this subsection shall be exhausted in its entirety before initiation of litigation. Failure to comply with the requirements set forth in this subsection , including notice requirements, shall bar either party from any further administrative, equitable, or legal remed ies. Subject to the rebuttable presumption of prejudice to CDOT set forth above, i f a deadline is missed that does not prejudice either party, further relief shall be allowed. All written notices of dispute shall be submitted within 30 days of date of the Project Engineer’s Final Acceptance letter; see subsection 105.21(b). When a project has a landscape maintenance period, the Project Engineer will grant partial acceptance per subsection 105.21(a). This partial acceptance will be project acceptance of all the construction work performed before this partial acceptance. All disputes and claims related to the work in which this partial acceptance is granted shall be submitted within 30 days of the Project Engineer’s partial acceptance. Should the Contractor’s dispute use the Total Cost approach for calculating damages, damages will be determined by subtracting the contract amount from the total cost of performance. Should the Contractor’s dispute use the Modified Total Cost approach for calculating damages, if the Contractor’s bid was unrealistic in part, or some of its costs were unreasonable or some of its damages were caused by its own errors, those costs and damages will be deducted from the total cost of performance to arrive at the Modified Total Cost. The Total Cost or Modified Total Cost basis for calculating damages shall not be available for any disputes or claims seeking damages where the Contractor could have kept separate cost records at the time the dispute arose as described in subsection 105.22(a).
a.Document Retention . The Contractor shall keep full and complete records of the costs and additional time incurred for each dispute for a period of at least three years after the date of final payment or until dispute is resolved, whichever is more. The Contractor, subcontractors, and lower tier subcontractors shall provide adequate facilities, acceptable to t he Engineer, for an audit during normal business hours. The Contractor shall permit the Engineer or Department auditor to examine and copy those records and all other records required by the Engineer to determine the facts or contentions involved in the dispute. The Contractor shall identify and segregate any documents or information that the Contractor considers particularly sensitive, such as confidential or proprietary information. Throughout the dispute, the Contractor and the Project Engineer shall keep complete daily records of extra costs and time incurred, per the following procedures:
1.Daily records shall identify each operation affected, the specific locations where work is affected, and the potential effect to the project’s schedule. Such records shall also reflect all labor, material, and equipment applicable to the affected operatio ns.
2.On the first workday of each week following the date of the written notice of dispute, the Contractor shall provide the Project Engineer with the daily records for the preceding week. If the Contractor’s records indicate costs greater than those kept by the Department , the Project Engineer will meet with the Contractor and present his records to the Contractor at the meeting. The Contractor shall notify the Engineer in writing within three workdays of any inaccuracies noted in, or disagreements with, the Department’s records. 105.22 105-43 (b) Initial Dispute Resolution Process . To initiate the dispute resolution process, the Contractor shall provide a written notice of dispute to the Project Engineer upon the failure of the Parties to resolve the issue through negotiation. Disputes will not be considered unless the Contractor has first complied with specified issue resolution processes such as those specified in subsections 104.02, 106.05, 108.08(a), and 108.08(d). The Contractor shall supplement the written notice of dispute within 15 days with a written Request for Equitable Adjustment (REA) providing the following:
1.The date of the dispute.
2.The nature of the circumstances that caused the dispute.
3.A detailed explanation of the dispute citing specific provisions of the Contract and any basis, legal or factual, that support the dispute.
4.If any, the estimated quantum, calculated per methods set forth in subsection 105.24(b)12., with supporting documentation.
5.An analysis of the progress schedule showing the schedule change or disruption if the Contractor is asserting a schedule change or disruption. This analysis shall meet the requirements of subsection 108.08(d). The Contractor shall submit as much information on the quantum and impacts to the Contract time as is reasonably available with the REA and then supplement the REA as additional information becomes available. If the dispute escalates to the DRB process, neither party shall provide or present to the DRB any issue or any information that was not contained in the REA and fully submitted in writing to the Project Engineer and Resident Engineer during the subsection 105.22 process.
c.Project Engineer Review . Within 15 days after receipt of the REA, the Project Engineer will meet with the Contractor to discuss the merits of the dispute. Within seven days after this meeting, the Project Engineer will issue a written decision on the merits of the dispute. The Project Engineer will either deny the merits of the dispute or notify the Contractor that the dispute has merit. This determination will include a summary of the relevant facts, Contract provisions supporting the determination, and an evaluation of all scheduling issues that may be involved. If the dispute is determined to have merit, the Contractor and the Project Engineer will determine the adjustment in payment, schedule, or both within 30 days. When a satisfactory adjustment is determined, it shall be implemented per subsections 106.05, 108.08, 109.04, 109.05 or 109.10 and the dispute is resolved. If the Contractor accepts the Project Engineer's denial of the merits of the dispute, the dispute is resolved, and no further action will be taken. If the Contractor does not respond in seven days, it will be assumed he has accepted the denial. If the Contractor rejects the Project Engineer 's denial of the merits of the dispute or a satisfactory adjustment of payment or schedule cannot be agreed upon within 30 days, the Contractor may further pursue resolution of the dispute by providing written notice to the Resident Engineer within seven d ays, according to subsection 105.22(d).
d.Resident Engineer Review . Within seven days after receipt of the Contractor 's written notice to the Resident Engineer of unsatisfactory resolution of the dispute, the Project Engineer and Resident Engineer will meet with the Contractor to discuss the dispute. 105.23 105-44 Meetings shall continue weekly for a period of up to 30 days and shall include a Contractor's representative with decision authority above the project level. If these meetings result in resolution of the dispute, the resolution will be implemented per subsections 108.08, 109.04, 109.05, or 109.10 and the dispute is resolved. If these meetings do not result in a resolution or the participants mutually agree that they have reached an impasse, the dispute shall be presented to the Dispute Review Board per subsection 105.23.
105.23 Dispute Review Board . A Dispute Review Board (DRB ) is an independent third party
that will provide specialized expertise in technical areas and administration of construction contracts. The DRB will assist in and facilitate the timely and equitable resolution of disputes between CDOT and the Contractor in an effort to avoid animosity and construction delays, and to resolve disputes as close to the project level as possible. The DRB shall be established and operate as provided and shall serve as an independent and impartial board. A DRB member shall not be called as witness for future litigation. There are two types of DRBs: the “On Demand DRB” and the “Standing DRB”. The DRB shall be an “On Demand DRB” unless a “Standing DRB” is specified in the Contract. An On Demand DRB shall be established only when the Project Engineer initiates a DRB review per subsection 105.23(a). A Standing DRB, when specified in the Contract, shall be established at the beginning of the project.
a.Initiation of Dispute Review Board Review . When a dispute has not been resolved per subsection 105.22, the Project Engineer will initiate the DRB review process within five days after the period described in subsection 105.22(d).
b.Formation of Dispute Review Board. DRBs will be established per the following procedures:
1.CDOT, in conjunction with the Colorado Contractors Association (CCA) , will maintain a statewide list of pre- approved DRB candidates experienced in construction processes and the interpretation of contract documents and the resolution of construction disputes. Only individuals who have completed training (currently titled DRB Administration and Practice Training) through the Dispute Resolution Board Foundation or otherwise approved by CDOT can be a DRB member. DRB nominees shall be selected from the list of pre -approved candidates. When a DRB is formed, the parties shall execute the agreement set forth in subsection 105.23(l).
2.If the dispute has a value of $250,000 or less, the On Demand DRB shall have one member. The Contractor and CDOT shall select the DRB member and execute the Three -Party Agreement within 30 days of initiating the DRB process. If the parties do not agree on the DRB member, each shall select five candidates. Each party shall numerically rank their list using a scale of one to five with one being their first choice and fiv e being their last choice. If common candidates are listed, but the parties cannot agree, that common candidate with the lowest combined numerical rank ing shall be selected. If there is no common candidate, the lists shall be combined, and each party shall eliminate three candidates from the list. Each party shall then numerically rank the remaining candidates, with N umber 1 being the first choice. The candidate with the lowest combined numerical ranking shall be the DRB member. The CDOT Projec t Engineer will be responsible for having all parties execute the agreement. 105.23 105-45 3. If the dispute has a value over $250,000, the On Demand DRB shall have three members. The Contractor and CDOT shall each select a member and those two members shall select a third. Once the third member is approved, the three members will nominate one of them to be the Chair and execute the Three -Party Agreement within 45 days of initiating the DRB process.
4.The Standing DRB shall always have three m embers. The Contractor and CDOT shall each select a member and those two members shall select a third member. Once the third member is approved the three members will nominate one of them to be the Chair. The Contractor and CDOT shall submit their propos ed Standing DRB members within five days of execution of the Contract. The third member shall be approved before the Pre- construction Conference. The third member shall be selected within 15 days of execution of the Contract. Before construction startin g, the parties shall execute the Three -Party Agreement. The CDOT Project Engineer will be responsible for having all parties execute the agreement. The Project Engineer will invite the Standing DRB members to the Pre- construction and any Project First conferences.
5.DRB members shall not have been involved in the administration of the project under consideration. CDOT and the Contractor shall inform its selected DRB member who the major firms/people are on the project and request its selected DRB member to review the CDOT disclosure requirements and Canon of Ethics and then submit a disclosure statem ent which shall also be submitted to the other party. DRB candidates shall complete the DRB Disclosure Requirements and DRB Nominee Disclosure Form and disclose to the parties the following relationships:
1.Prior employment with either party
2.Prior or current financial interests or ties to either party
3.Prior or current professional relationships with either party
4.Anything else that might bring into question the impartiality or independence of the DRB member.
5.Before agreeing to serve on a DRB, members shall notify all parties of any other CDOT DRB’s they are serving or that they will be participating in another DRB. If either party objects to the selection of the chair or other DRB members based on the disclosures, or based on information not disclosed, which might bring into question the impartiality, independence, or performance of the potential member, that potential member shall not be placed on the Board.
6.There shall be no ex parte communications with the DRB at any time.
7.The service of a Board member may be terminated only by written agreement of both parties.
c.If a Board member resigns, is unable to serve, or is terminated, a new Board member shall be selected within four weeks in the same manner as the Board member who was removed was originally selected.
d.Additional Responsibilities of the Standing Disputes Review Board
1.General. No later than 10 days after the Three -Party Agreement has been signed by the Chief Engineer, the DRB will coordinate with the parties on the date and location of the initial DRB meeting. 105.23 105-46 (1) Obtain copies of the Contract documents and Contractor’s schedules for each of the Board members.
2.Agree on the location of future meetings, which shall be reasonably close to the project site.
3.Establish an address and telephone number for each Board member for the purposes of Board business.
2.Regular meetings. Regular meetings of the Board shall be held approximately every 120 to 180 days throughout the life of the Contract, except that this schedule may be modified to suit developments on the job as the work progresses. Regular meetings shall be attended by representatives of the Contractor and the Department.
3.The Board shall establish an agenda for each meeting which will cover all items that the Board considers necessary to keep it abreast of the project such as construction status, schedule, potential problems and solutions, status of past claims and disputes, and potential claims and disputes. Copies of each agenda shall be submitted to the Contractor and the Department at least seven days before the meeting date. Oral or written presentations or both shall be made by the Contractor and the Department as necessary to give the Board all the data the Board requires to perform its functions. The Board will prepare minutes of each meeting, circulate them to all participants for comments and approval, and issue revised minutes before the next meeting. As a part of each regular meeting, a field inspection trip of all active segments of the work at the project site may be made by the Board, the Contractor, and the Department.
4.Advisory Opinions
1.Advisory opinions are typically used soon after the parties find they have a potential dispute and have conducted preliminary negotiations but before expenditure of additional resources and hardening their positions. Advisory opinions provide quick insight into the DRB’s likely assessment of the dispute. This process is quick and may be ent irely oral and does not prejudice the opportunity for a DRB hearing.
2.Both parties must agree to seek an advisory opinion and so notify the chairperson. The procedure for requesting and issuing advisory opinions should be discussed with the DRB at the first meeting with the parties.
3.The DRB shall issue a one- page written opinion within 5 days of the hearing.
4.The opinion is only advisory and does not require an acceptance or rejection by either party. If the dispute is not resolved and a hearing is held, the oral presentations and advisory opinion are completely disregarded and the DRB hearing procedure is foll owed.
5.Advisory opinions should be limited to merit issues only.
e.Arranging a Dispute Review Board Hearing . When the Project Engineer initiates the DRB review process, the Project Engineer will:
1.Contact the Contractor and the DRB to coordinate an acceptable hearing date and time. The hearing shall be held at the Resident Engineer’s office unless an alternative location is agreed to by both parties. Unless otherwise agreed to by both parties an O n Demand DRB hearing will be held within 30 days after the Three -Party Agreement is signed by the CDOT Chief Engineer. Unless otherwise agreed to by both parties, a Standing DRB hearing will be held within 30 days after the DRB has been requested per subsection 105.23(a). 105.23 105-47 2. Ensure DRB members have copies of all documents previously prepared by the Contractor and CDOT pertaining to the dispute , the DRB request, the Contract documents, and the special provisions at least two weeks before the hearing.
f.Pre-Hearing Submittal . All Pre- hearing Submittals shall include only arguments, supporting documentation, quantum, and other information as previously submitted in writing and as previously disputed in the formal dispute process covered in subsection 105 .22(b), (c), and (d). All Pre -hearing Submittals planned to be used at the hearing, shall be submitted to the other party 35 days before the hearing for review for compliance with this requirement. If either party contends there are new arguments, supporting documents, new quantum, o r any new information in a pre -hearing Submittal, and the other party objects to this information being presented to the DRB, the objecting party shall submit its objections in writing to the other party within 10 days. The parties shall meet within five days to reconcile the objection before the submittal is submitted to the DRB. If the parties cannot reconc ile the objection, but the new argument, supporting documentation, new quantum, or new information does not change either party’s position on merit or quantum, the information shall be allowed in the Pre- hearing submittal and presented to the DRB. If the parties cannot reconcile the objections within the five days allowed, each party shall submit a one -page brief on their objections, but not the actual information objected to, to the DRB for a decision on the use of the documents. The DRB shall not approv e any information simply because it is relevant to the dispute or referenced during the dispute. Neither party shall attempt to present anything to the DRB which they did not present to the other party during the dispute process. The dispute process shall be delayed while this determination is being made and a new hearin g date set, if necessary. Pre- hearing Submittals to the DRB are as follows:
1.Joint Statement: At least 20 days before the hearing the Joint Statement(s) shall be submitted to the DRB. The parties shall make every attempt to agree upon a Joint Statement of the dispute. If the parties cannot agree on the Joint Statement, each party’s independent statement shall be submitt ed to the DRB. The Joint Statement shall summarize, in a few sentences, the nature of the dispute(s) and the scope of the desired decision.
2.Position Paper: At least 15 days before the hearing, CDOT and the Contractor shall submit by email to the DRB Chairperson their party’s Position Paper. The DRB Chairperson shall simultaneously distribute by email the Position Papers to all parties and other DRB members, if any. The Position P aper shall contain the following:
1.The basis and justification for the party’s position, with reference to specific contract language and the supporting documents of each element of the disputes.
2.A list of proposed attendees for the hearing. In the event of any objection by a party, the DRB shall make a final determination as to who attends the hearing.
3.When the scope of the hearing includes quantum, full cost details will be calculated per methods set forth in subsection 105.24(b)12. The Scope of the hearing will not include quantum if CDOT has requested an audit that has not been completed. 105.23 105-48 3. Supporting Documents : At least 15 days before the hearing, each party shall submit a copy of all its supporting documents to the DRB and the other party. Supporting documents include any presentations, visuals, or handouts planned to be used at the hearing. To minimize duplication and repetitiveness, the parties are encouraged to identify a common set of documents that will be referred to by both parties and submit them in a separate package to the DRB at least 20 days before the hearing. Common documents are communications between parties, speed m emos, change orders, schedules, request for equitable adjustment, and correspondence, and any document used in the subsection 105.22 process. CDOT shall submit the common set of documents to the Board and Contractor.
4.If relevant to the dispute and requested by the Board, the Engineer shall provide to the DRB either website links, electronic PDFs, or hard copies of pertinent contract documents such as plans, specifications, and M and S Standards.
g.Pre-Hearing Phone Conference. A pre -hearing phone conference with all Board members and the parties shall be conducted as soon as a hearing date is established, but no later than 10 days before the hearing. The DRB Chairperson shall explain the specifics of how the hearing will be conducted including how the two parties will present their information. (Ex. Each party makes a full presentation of their positions or presentations will be made on a “point by point” basis with each party making a presentation only on the individual disp ute issue before moving onto the next issue.) If the pre -hearing position papers and documents have been received by the DRB before the conference call, the Chairperson shall discuss the estimated hours of review and activities for the disputes (such as time spent evaluating and preparing recommendation on specific issues presented to the DRB). If the pre- hearing position papers and documents have not been received by the Board before the conference call, another conference call will be scheduled during the initial conference call to discuss the estimated hours of review. The Engineer shall coordinate the conference call.
h.Dispute Review Board Hearing . The DRB shall preside over a hearing. The chairperson shall control the hearing and conduct it as follows:
1.An employee of CDOT presents a brief description of the project and the status of construction on the project.
2.The party that requested the DRB presents the dispute in detail as supported by previously submitted information and documentation in the pre -hearing position paper. No new information or disputes will be heard or addressed by the DRB. Rebuttals of the o ther party’s arguments shall not be presented at this time.
3.The other party presents its position in detail as supported by previously submitted information and documentation.
4.The party that requested the DRB presents their rebuttals followed by the other party’s rebuttals.
5.Upon completion of their presentations and rebuttals, both parties and the DRB will be provided the opportunity to exchange questions and answers. Questions from the parties shall be directed to the Chairperson. Attendees may respond only when board memb ers request a response.
6.Employees of each party are responsible for leading presentations at the DRB hearing. 105.23 105-49 7. Attorneys shall not participate in the hearing unless the DRB specifically addresses an issue to them or unless agreed to by both parties. Should the parties disagree on attorney participation, the DRB shall decide on what, if any, participation will be permitted. Attorneys representing the parties are permitted to attend the hearing, provided their presence has been noted in the pre -hearing submittal.
8.Either party may use experts only if the expert has previously presented to the other party before the DRB process. A party intending to offer an outside expert's analysis at the hearing shall disclose such intention in the pre- hearing position paper. The expert's name and a general statement of the area of the dispute that will be covered by his presentation shall be included in the disclosure. The other party may present an outside expert to address or respond to those issues that may be raised by the disclosing party's outside expert.
9.If both parties approve, the DRB may retain an outside expert. The DRB chairperson shall include the cost of the outside expert in the DRB's regular invoice. CDOT and the Contractor shall equally bear the cost of the services of the outside expert employ ed by the DRB.
10.If either party attempts to present an argument, documentation, quantum, or new information which the other party feels was not in the Pre -hearing submittals, the chairperson shall require the party t o demonstrate where in the Pre- hearing submittal the information in question resides.
11.If either party fails to timely deliver a position paper, the DRB may reschedule the hearing one time. On the final date and time established for the hearing, the DRB shall proceed with the hearing using the information that has been submitted.
12.If a party fails to appear at the hearing, the DRB shall proceed as if all parties were in attendance.
i.Dispute Review Board Recommendation . The DRB shall issue a Recommendation per the following procedures:
1.The DRB shall not make a recommendation on the dispute at the meeting. Before the closure of the hearing, the DRB members and the Contractor and CDOT together will discuss the time needed for analysis and review of the dispute and the issuance of the DRB’s recommendation. The maximum time shall be 30 days unless otherwise agreed t o by both parties.
2.After the meeting has been closed, the DRB shall prepare a written Recommendation signed by each member of the DRB. In the case of a three member DRB where one member dissents, that member shall prepare a written dissent and sign it. The DRB‘s recommendation shall include the following:
A.A summary of the issues and factual evidence presented by the Contractor and CDOT concerning the dispute.
B.Recommendations concerning the validity of the dispute.
C.Recommendations concerning the value of the dispute as to cost impacts if the dispute is determined to be valid.
D.The contractual and factual bases supporting the recommendation(s) made including an explanation as to why each and every position was accepted or rejected.
E.Detailed and supportable calculations which support any recommendation(s). 105.23 105-50 3. The chairperson shall transmit the signed Recommendation and any supporting documents to both parties.
j.Clarification and Reconsideration of Recommendation . Either party may request in writing clarification or reconsideration of a decision within 10 days following receipt of the Recommendation. Within 10 days after receiving the request, the DRB shall provide written clarification or reconsideration to both parties. Requests for clarification or reconsideration shall be submitted in writing simultaneously to the DRB and to the other party. The Board shall not accept requests for reconsideration that amount to a renewal of a prior argument or additional argument based on facts available at the time of the hearing. The Board shall not consider any documents or arguments which have not been made a part of the pre- hearing submittal other than clarification and data supporting previously submitted documentation.

105.24 Claims for Unresolved Disputes. The Contractor may file a claim only if the disputes
resolution process described in subsections 105.22 and 105.23 has been exhausted without resolution of the dispute. Other methods of nonbinding dispute resolution, exclusive of litigation, can be used if agreed to by both parties. This subsection applies to any unresolved dispute or set of disputes between CDOT and the Contractor with an aggregate value of more than $15,000. Unresolved disputes with an aggregate value of more than $15,000 from subcontractors, materials suppliers or any other entity not a party to the Contract shall be submitted through the Contractor per this subsection as a pass -through claim. Review of a pass -through claim does not create privity of Contract between CDOT and any other entity. Subsections 105.22, 105.23 and 105.24 provide both contractual alternative dispute resolution processes and constitute remedy -granting provisions pursuant to Colorado Revised Statutes (CRS) which must be exhausted in their entirety. Litigation proceedings must commence within 180 -calendar days of the Chief Engineer's decision, absent written agreement otherwise by both parties. The venue for all unresolved disputes with an aggregate value $15,000 or less shall be the County Court for the City and County of Denver. Non-binding Forms of alternative dispute resolution such as Mediation are available upon mutual agreement of the parties for all claims submitted per this subsection. The cost of the non -binding ADR process shall be shared equally by both parties with each party bearing its own preparation costs. The type of nonbinding ADR process shall be agreed upon by the parties and shall be conducted within the State of Colorado at a mutually acceptable location. Participation in a nonbinding ADR process does not in any way waive the requirement that litigation proceedings must commence within 180 -calendar days of the Chief Engineer's decision, absent written agreement otherwise b y both parties.
a.Notice of Intent to File a Claim . Within 30 days after rejection of the Dispute Resolution Board’s Recommendation issued per subsection 105.23, the Contractor shall provide the Region Transportation Director (RTD) with a written notice of intent to file a claim.

Consolidation of unrelated claims will not be made. The RTD will render a written decision to the Contractor within 9 0 days after the receipt of the claim package or receipt of the audit whichever is later. In rendering the decision, the RTD: (1) will review the information in the Contractor's claim; (2) will conduct a hearing if requested by either party; and (3) may consider any other information available in rendering a decision. The RTD will assemble and maintain a claim record comprised of all information physically submitted by the Contractor in support of the claim and all other discoverable information considered by the RTD in reaching a decision. Once the RTD assembles the claim record, the submission and consideration of additional information, other than for clarification and data supporting previously submitted documentation, at any subsequent level of review by anyone, will not be permitted. The RTD will provide a copy of the claim record and the written decision to the Contractor describing the information considered by the RTD in reaching a decision and the basis for that decision. If the RTD fails to render a written decision within the 60 -day period, or within any extended time period as agreed to by both parties, the Contractor shall either:
1.accept this as a denial of the claim, or (2) appeal the claim to the Chief Engineer, as described in this subsection. If the Contractor accepts the RTD decision, the provisions of the decision shall be implemented per subsections 108.08, 109.04, 109.05, or 109.10 and the claim is resolved. If the Contractor disagrees with the RTD decision, the Contractor shall either: (1) accept the RTD decision as final, or (2) file a written appeal to the Chief Engineer within 30 days from the receipt of the RTD decision. The Contractor hereby agrees that if a written appeal is not properly filed, the RTD decision is final.

The Chief Engineer will not consider any information that was not previously made a part of the claim record, other than clarification and data supporting previously submitted documentation. The Contractor shall have 30 days to accept or reject the Chief Engineer's decision. The Contractor shall notify the Chief Engineer of its acceptance or rejection in writing. If the Contractor accepts the Chief Engineer's decision, the provisions of the decision will be implemented per subsections 108.08, 109.04, 109.05, or 109.10 and the claim is resolved. If the Contractor disagrees with the Chief Engineer's decision, the Contractor shall either
1.pursue an alternative dispute resolution process per this specification or (2) initiate litigation per subsection 105.24(f). If the Chief Engineer does not issue a decision as required, the Contractor may immediately initiate litigation per subsection 105.24(f). For the convenience of the parties to the Contract it is mutually agreed by the parties that any merit binding or De Novo litigation shall be brought within 180 -calendar days from the date of the Chief Engineer's decision. The parties understand and agree that the Contractor's failure to bring suit within the time period provided, shall be a complete bar to any such claims or causes of action.
e.De Novo Litigation . If the Contractor disagrees with the Chief Engineer's decision, the Contractor may initiate de novo litigation to finally resolve the claim that the Contractor submitted to CDOT. Such litigation shall be strictly limited to those claims that were previously submitted and decided in the contractual dispute and claims processes outlined. This does not preclude the joining in one litigation of multiple claims from the same project provided that each claim has gone through the dispute and claim process specified in subsections 105.22 through 105.24. The parties may agree, in writing, at any time, to pursue some othe r form of alternative dispute resolution. Any offer made by the Contractor or the Department at any stage of the claims process, as set forth in this subsection, shall be deemed an offer of settlement pursuant to Colorado Rule of Evidence 408 and therefore inadmissible in any litigation. If the Contractor selected litigation, then de novo litigation shall proceed per the Colorado Rules of Civil Procedure and the proper venue is the Colorado State District Court in and for the City and County of Denver.

requirements of the Contract. The Contractor shall comply with the requirements of the special notice to contractors contained in the Department’s Field Materials Manual, including notifying the Engineer of the proposed sources of materials at least two weeks before delivery. When alternative materials are permitted for an item in the Contract, the Contractor shall state at the Pre -construction Conference the material that will be furnished for that item. Reference in the Contract to a particular product or to the product of a specific manufacturer, followed by the phrase “or approved equal”, is intended only to establish a standard of quality, durability, and design, and shall not be construed as limiting competition. Products of other manufacturers will be acceptable provided such products are equal to that specified. All suppliers who provide one or more of the following elements in which the cost exceeds $10,000 shall create an account in the B2GNow software system.
a.Fabrication of material
b.Processing of materials
c.Delivery service cost of the material delivered to the project. If the supplier does not have an account created, approval of the Form 1425 may be withheld. The Contractor shall submit a completed Form 1425 for each direct supplier that meets the $10,000 criteria outlined above via the B2GNow software system. The Form 1425 shall be submitted to the Engineer before beginning work on the project, incorporating materials into the project or at such time that the $10,000 amount is known to be exceeded. If an individual, firm, or corporation is responsible for the installation of supplies, a Form 205 shall be required for the subcontractor. The supplier shall notify the Contractor if an individual spends more than 20 percent of their workweek performing actual construction work such as installation, repair or warranty work, on the site of work as that would require the submission of a Form 205 and certified payrolls. During the performance of the project, the Contractor shall submit an updated Form 1425 if information changes. Each subcontractor or supplier at any tier meeting the $10,000 requirement above shall submit a Form 1425 to the Contractor, who will then submit it to the Department.
