Modifications were made to section 4 by the County and approved by the City. 1/3/22 1/4/22 Page 1 of 5 SETTLEMENT AGREEMENT AND RELEASE OF CLAIMS BETWEEN KING COUNTY AND CITY OF KENT FOR THE CONSTRUCTION OF 84TH AVENUE EAST VALLEY HIGHWAY SLUMP REPAIR WORK This Settlement Agreement and Release of Claims (the “Settlement Agreement”) is made and entered into by and between King County, a home-rule charter County and political subdivision of the State of Washington (“King County” or the “County”) and the City of Kent a municipal corporation of the State of Washington (the “City”). The County and City may be referred to herein individually as a “Party” and collectively as the “Parties.” RECITALS A. A portion of the City street located approximately north of the intersection of 84th Avenue South (East Valley Highway) and South 222nd Street, in the City of Kent Washington, (hereinafter the “Street Settlement Area”) has experienced unusual settlement. B. A section of County sewer pipeline between Manhole 57G and Manhole 57H crosses beneath the Street Settlement Area. This sewer pipeline also experienced unusual settlement and damage. C. The City has made repairs to the street in the vicinity of the Street Settlement Area and has sent the County invoices totaling $42,758.10 for said repairs (the “City Repair Invoices”). The County denies any liability for either the settlement in the Street Settlement Area or for the City Repair Invoices. D. On or about September 30, 2015, the City and County entered into an interagency agreement to jointly fund certain subsurface explorations in the vicinity of the Street Settlement Area and the sewer pipeline settlement, including the construction of five borings, temporary installation of five monitoring wells, and the preparation of a geotechnical data report. E. In February 2017, the County completed repairs to the sewer pipeline in the area between Manhole 57G and Manhole 57H using a cured-in-place pipe (CIPP) method. F. King County applied for and received from the City, a street use permit for the County’s CIPP project (the “City Permit”) to complete a repair of the sewer pipeline using in situ pipe lining. The repair of the sewer pipeline was completed to King County’s satisfaction. G. In an effort to resolve disputes with the City regarding repairs to the street in the vicinity of the Street Settlement Area and the City Repair Invoices, the County, without admitting any liability, offered to repair the sidewalk, curb and gutter and grind and overlay the roadway asphalt in the vicinity of the County’s sewer pipeline work in exchange for a release and discharge of claims from the City. The City asserted that the scope of the street repairs proposed by the County was inadequate. H. The Parties now desire to resolve their current disputes regarding repairs to the street in the vicinity of the Street Settlement Area and the City Repair Invoices.

Failure of the Bidder to submit, within one hour after the published bid submittal time, the names of such subcontractors or to name itself to perform such work or the naming of two or more subcontractors to perform the same work shall render the Bidder’s Bid non-responsive and, therefore, void.

THIS FORM INCLUDES CRITERIA ESTABLISHED BY STATE LAW THAT MUST BE MET TO BE CONSIDERED A RESPONSIBLE BIDDER AND QUALIFIED TO BE AWARDED THIS PUBLIC WORKS PROJECT AS WELL AS SUPPLEMENTAL CRITERIA ESTABLISHED BY THE CITY THAT ARE APPLICABLE TO THIS PUBLIC WORKS PROJECT. THE BIDDER SHOULD READ AND RESPOND TO THIS FORM CAREFULLY. Indicia of contractor’s responsibility inherently involve subjective determinations as to the contractor’s ability to perform and complete the contract work responsibly and to the owner city’s satisfaction. The city has an obligation and a duty to its citizens and its taxpayers to administer its budgets and complete its projects in a businesslike manner. Accordingly, it has a duty to exercise the type of inquiry and discretion a business would conduct when selecting a contractor who will be responsible to perform the contract work. The city’s supplemental criteria are based, in large part, on the qualification statement form used by the American Institute of Architects. The city provides these criteria so as to provide the most objective framework possible within which the city will make its decision regarding the bidder’s ability to be responsible to perform the contract work. These criteria, taken together, will form the basis for the city’s decision that a bidder is or is not responsible to perform the contract work. Any bidder may make a formal written request to the city to modify the criteria set forth in this qualification statement, but that request may only be made within 48 hours of the date and time that the bidder first obtains the bid documents or three (3) business days prior to the scheduled bid opening date, whichever occurs first. If the city receives a modification request, it will consider any information submitted in the request and will respond before the bid submittal deadline. If the city’s evaluation results in changed criteria, the city will issue an addendum establishing the new or modified criteria. If the city determines that, based on the criteria established in this statement, a bidder is not responsible to perform the contract work, the city will provide written notice of its determination that will include the city’s reason for its decision. The bidder has 24 hours from the time the city delivers written notice to the bidder that the bidder is not responsible to perform the contract work to appeal the city’s determination. No appeals will be received after the expiration of this 24 hour appeal period. The city may deliver this notice by hand delivery, email, facsimile, or regular mail. In the event the city uses regular mail, the delivery will be deemed complete three days after being placed in the U.S. Mail. The bidder’s right to appeal is limited to the single remedy of providing the city with additional information to be considered before the city issues a final determination. Bidder acknowledges and understands that, as provided by RCW 39.04.350, no other appeal is allowed and no other remedy of any kind or nature is available to the bidding contractor if the City determines that the bidder is not responsible to perform the contract work. EVH Slump Repair/Holcomb 20 November 18, 2021 Project Number: 15-3009 If the bidder fails to request a modification within the time allowed, or fails to appeal a determination that the bidder is not responsible within the time allowed, the city will make its determination of bidder responsibility based on the information submitted.

SECTION 1-05.7 IS SUPPLEMENTED BY ADDING THE FOLLOWING: 1-05.7 Removal of Defective and Unauthorized Work If the Contractor fails to remedy defective or unauthorized work within the time specified by the Engineer, or fails to perform any part of the work required by the contract, the Engineer may provide the Contractor written notice establishing a date after which the City will correct and remedy that work by any means that the Engineer may deem necessary, including the use of City forces or other contractors. If the Engineer determines that the Contractor’s failure to promptly correct any defective or any unauthorized work creates a situation that could be potentially unsafe or might cause serious risk of loss or damage to the public, the Engineer may have the defective and unauthorized work corrected immediately, have the rejected work removed and replaced, or have the work the Contractor refuses to perform completed by using City or other forces. Direct and indirect costs incurred by the City attributable to correcting and remedying defective or unauthorized work, or work the Contractor failed or refused to perform, shall be paid by the Contractor. Payment may be deducted by the Engineer from monies due, or to become due, the Contractor. Direct and indirect costs shall include, without limitation, compensation for additional professional services required, compensation and engineering and inspection services required, and costs for repair and replacement of work of others destroyed or damaged by correction, removal, or replacement of the Contractor’s unauthorized work.

EVH Slump Repair/Holcomb 1 - 9 November 18, 2021 Project Number: 15-3009 DIVISION 1 IS SUPPLEMENTED BY ADDING THE FOLLOWING NEW SECTIONS: 1-05.8 City Provided Construction Staking 1-05.8(1) General As used in this Section 1-05.5, the words, “stake,” “mark,” “marker,” or “monument” will be deemed to include any kind of survey marking, whether or not set by the City. The City will supply construction stakes and marks establishing lines, slopes and grades as set forth in Sections 1-05.8(2) through 1-05.8(6) of the Kent Special Provisions. The Contractor shall assume full responsibility for detailed dimensions, elevations, and excavation slopes measured from these City furnished stakes and marks. The Contractor shall provide a work site clear of equipment, stockpiles and obstructions which has been prepared and maintained to permit construction staking to proceed in a safe and orderly manner. A City survey crew can stake a finite amount of work in a single day (see Section 1-05.8(6) of the Kent Special Provisions). The Contractor shall provide staking requests for a reasonable amount of work to the Engineer at least 3 working days in advance to allow the survey crew adequate time for setting stakes. If the work site is obstructed so that survey work cannot be done, a new request for work shall be submitted by the Contractor so that the survey can be rescheduled once the site is properly prepared. Up to an additional 3 working days may be required depending on work load for the city survey crew to complete the rescheduled work. Note: A surveyor working day is a consecutive eight hour period between 7:00 AM and 6:00 PM, Monday through Friday, except holidays as listed in Section 1-08.5. It is illegal under Revised Code of Washington 58.09.130 and Washington State Administrative Code 332-120 to willfully destroy survey markers. Stakes, marks, and other reference points set by City forces, and existing City, State or Federal monumentation, shall be carefully preserved by the Contractor. The Contractor shall notify the Engineer immediately if it becomes apparent that a survey marker will be disturbed due to construction. The Contractor will allow ample time for City Survey Department personnel to acquire adequate information so that the monument may be replaced in its original position after construction. If the City is not notified, and a stake, marker or monument is disturbed or destroyed the Contractor will be charged at a rate of $300/hour for a city survey crew to replace the stake, marker or monument that was not to be disturbed or damaged by the Contractor’s operations. This charge will be deducted from monies due or to become due to the Contractor. Any claim by the Contractor for extra compensation by reason of alterations or reconstruction work allegedly due to error in the Surveyor’s line and grade will not be allowed unless the original control points set by the Surveyor still exist, or unless the Contractor can provide other satisfactory substantiating evidence to prove the error EVH Slump Repair/Holcomb 1 - 10 November 18, 2021 Project Number: 15-3009 was caused by incorrect city-furnished survey data. Three consecutive points set on line or grade shall be the minimum points used to determine any variation from a straight line or grade. Any such variation shall, upon discovery, be reported to the Engineer. In the absence of such report, the Contractor shall be liable for any error in alignment or grade. 1-05.8(2) Roadway and Utility Surveys The Engineer shall furnish to the Contractor, one time only, all principal lines, grades and measurements the Engineer deems necessary for completion of the work. These shall generally consist of one initial set of: 1. Cut or fill stakes for establishing grade and embankments, 2. Curb or gutter grade stakes, 3. Centerline finish grade stakes for pavement sections wider than 25 feet as set forth in Section 1-05.8(5), subsection 2, and 4. Offset points to establish line and grade for underground utilities such as water, sewers, storm drains, illumination and signalization. No intermediate stakes shall be provided between curb grade and centerline stakes. On alley construction projects with minor grade changes, the Engineer shall provide offset hubs on one side of the alley to establish the alignment and grade. Alleys with major grade changes shall have embankments staked to establish grade before offset hubs are set. 1-05.8(4) Control Stakes Stakes that constitute reference points for all construction work will be conspicuously marked with an appropriate color of flagging tape. It will be the responsibility of the Contractor to inform its employees and subcontractors of the importance and necessity to preserve the stakes. The Contractor shall determine appropriate construction stake offset distances to prevent damage to stakes by its construction equipment. Should it become necessary, for any reason, to replace these control stakes, the Contractor will be charged at the rate of $300/hour for a city survey crew to replace the stakes. The Contractor may not charge the City for any standby or “down” time as a result of any replacement of control stakes. If the removal of a control stake or monument is required by the construction operations of the Contractor or its subcontractors, and advance notice of at least three (3) full working days is given to the City, the City will reference, remove, and later replace the stakes or monument at no cost to the Contractor. 1-05.8(5) Staking Services Work requests must be made at least 3 working days in advance of the required staking. EVH Slump Repair/Holcomb 1 - 11 November 18, 2021 Project Number: 15-3009 The City will furnish the following stakes and reference marks: 1. Clearing Limits - One set of clearing limit stakes will be set at approximately 25-foot stations where needed. 2. Rough Grading - One set of rough grade stakes will be set along the construction centerline of streets at 50-foot stations as required. (If superelevations require intermediate stakes along vertical curves, the City will provide staking at closer intervals.) One set of primary cut and fill stakes will be set for site work. One set of secondary final grade cut and fill stakes will be set where deemed applicable as determined by the Engineer. 3. Storm Sewers - Two cut or fill stakes for each inlet, catch basin or manhole will be set at appropriate offsets to the center of the structure. After installation and backfill, inverts will be checked for correctness. 4. Sanitary Sewers - Two cut or fill stakes for each manhole or cleanout location will be set at appropriate offsets to the center of the structure. After installation and backfill, inverts will be checked for correctness. 5. Water Main - One set of line stakes will be furnished for water mains at 50-foot stations. Additionally, two reference stakes for each valve, hydrant, tee and angle point location will be set concurrently with these line stakes. 6. Staking for Embankments - Catch points and one line stake will be set in those cases where the vertical difference in elevation from the construction centerline to the toe or top of a cut or fill slope exceeds 3 feet. In all other areas, stakes shall be set at an appropriate offset to the street centerline to allow for the preservation of said offsets through the rough grading phase. In both cases the stakes shall be clearly marked with appropriate information necessary to complete the rough grading phase. 7. Curb and Gutters - One set of curb and gutter stakes shall be set at an appropriate offset at 25-foot intervals, beginning and end points of curves and curb returns, wheelchair ramps, driveways, and sufficient mid-curve points to establish proper alignment. 8. Base and Top Course - One set of final construction centerline grade hubs will be set for each course, at not less than 50-foot stations. No intermediate stakes shall be provided unless superelevations require them. In those circumstances, one grade hub left and right of construction centerline at the transition stations will be set at an appropriate offset to centerline not less than 25-foot stations. 9. Adjacent or Adjoining Wetlands - One set of stakes delineating adjacent wetland perimeters will be set at 25 to 50-foot stations as required. 10. Illumination and Traffic Signals System - One set of stakes for luminaires and traffic signal pole foundations will be set as required. One set of stakes for vaults, junction boxes, and conduits will be set, only if curb and gutter is not in place at the time of the survey request. If curb and gutter is in place, staking for vaults, EVH Slump Repair/Holcomb 1 - 12 November 18, 2021 Project Number: 15-3009 junction boxes, and conduits will be provided at an additional expense to the Contractor. When deemed appropriate by the Engineer, cut sheets will be supplied for curb, storm, sanitary sewer and water lines. Cuts or fills may be marked on the surveyed points but should not be relied on as accurate until a completed cut sheet is supplied. The Contractor, at its own expense, shall stake all other items not listed above to construct the project per the Plans and Specifications. Staking for channelization, traffic loops, and all other items not listed above shall be the sole responsibility and expense of the Contractor. The City may, at its sole discretion, provide additional staking at the request of the Contractor at the rate of $300/hour. 1-05.8(6) Survey Requests It shall be the Contractor’s responsibility to properly schedule survey crews and coordinate staking requests with construction activities. A survey crew may be reasonably expected to stake any one of the following items, in the quantity shown, in a single day: Roadway grading +/-1500 lineal feet of centerline Storm or sanitary sewer Approximately 8-10 structures Water main +/-1500 lineal feet of pipe Curb and gutter +/-1300 lineal feet (one side only) Base and top course +/-1000 lineal feet of centerline Slope staking +/-800-1200 lineal feet (top and toe) Illumination/signalization Approximately 15-20 structures Actual quantities may vary based on the complexity of the project, line of sight considerations, traffic interference, properly prepared work site, and other items that could affect production. The Contractor shall be aware that length does not always translate directly into stationing. For example, a survey request for storm sewer pipe from Station 3+00 to 8+00 is 500 lineal feet in length. There may be 1000 lineal feet, or more, of storm sewer pipe, if the pipe is placed on both sides of the roadway and interconnected. SECTION 1-05.9 IS SUPPLEMENTED BY ADDING THE FOLLOWING NEW SUBSECTION: 1-05.9 Equipment 1-05.9(1) Operational Testing It is the intent of the City to have at the Physical Completion Date a complete and operable system. Therefore when the work involves the installation of machinery or other mechanical equipment, street lighting, electrical distribution of signal systems, building or other similar work, it may be desirable for the Engineer to have the EVH Slump Repair/Holcomb 1 - 13 November 18, 2021 Project Number: 15-3009 Contractor operate and test the work for a period of time after final inspection but prior to the Physical Completion Date. Whenever items of work are listed in the contract provisions for operational testing they shall be fully tested under operating conditions for the time period specified to ensure their acceptability prior to the Physical Completion Date. In the event the contract does not specify testing time periods, the default testing time period shall be twenty-one (21) calendar days. During and following the test period, the Contractor shall correct any items of workmanship, materials, or equipment that prove faulty or that are not in first class operating condition. Equipment, electrical controls, meters, or other devices and equipment to be tested during this period shall be tested under the observation of the Engineer, so that the Engineer may determine their suitability for the purpose for which they were installed. The Physical Completion Date cannot be established until testing and corrections have been completed to the satisfaction of the Engineer. The costs for power, gas, labor, material, supplies, and everything else needed to successfully complete operational testing shall be included in the various contract bid item prices unless specifically set forth otherwise in the contract. Operational and test periods, when required by the Engineer, shall not affect a manufacturer’s guaranties or warranties furnished under the terms of the Contract. SECTION 1-05.10 IS DELETED AND REPLACED WITH THE FOLLOWING: 1-05.10 Guarantees In addition to any other warranty or guarantee provided for at law or in the parties’ contract, the Contractor shall furnish to the Contracting Agency any guarantee or warranty furnished as a customary trade practice in connection with the purchase of any equipment, materials, or items incorporated into the project. Upon receipt of written notice of any required corrective work, the Contractor shall pursue vigorously, diligently, and without disrupting city facilities, the work necessary to correct the items listed in the notice. Approximately sixty (60) calendar days prior to the one year anniversary of final acceptance, the Contractor shall be available to tour the project, with the Engineer, in support of the Engineer’s effort to establish a list of corrective work then known and discovered. SECTION 1-05.13 IS REVISED BY INSERTING THE FOLLOWING PARAGRAPH AFTER THE FIRST PARAGRAPH: 1-05.13 Superintendents, Labor, and Equipment of Contractor EVH Slump Repair/Holcomb 1 - 14 November 18, 2021 Project Number: 15-3009 Within ten (10) days of contract award, the Contractor shall designate the Contractor's project manager and superintendent for the contract work.

Also, when a WMA additive is included in the manufacture of HMA, the discharge temperature of the HMA shall not exceed the maximum recommended by the manufacturer of the WMA additive. A maximum water content of 2 percent in the mix, at discharge, will be allowed providing the water causes no problems with handling, stripping, or flushing. If the water in the HMA causes any of these problems, the moisture content shall be reduced as directed by the Engineer. Storing or holding of the HMA in approved storage facilities will be permitted with approval of the Engineer, but in no event shall the HMA be held for more than 24 hours. HMA held for more than 24 hours after mixing shall be rejected. Rejected HMA shall be disposed of by the Contractor at no expense to the Contracting Agency. The storage facility shall have an accessible device located at the top of the cone or about the third point. The device shall indicate the amount of material in storage. No HMA shall be accepted from the storage facility when the HMA in storage is below the top of the cone of the storage facility, except as the storage facility is being emptied at the end of the Recycled asphalt pavement (RAP) utilized in the production of HMA shall be sized prior to entering the mixer so that a uniform and thoroughly mixed HMA is produced. If there is evidence of the recycled asphalt pavement not breaking down during the heating and mixing of the HMA, the Contractor shall immediately suspend the use of the RAP until changes have been approved by the Engineer. After the required amount of mineral materials, RAP, new asphalt binder and asphalt rejuvenator have been introduced into the mixer the HMA shall be mixed until complete and uniform coating of the particles and thorough distribution of the asphalt binder throughout the mineral materials, and RAP is ensured. 5-04.3(7) Spreading and Finishing The mixture shall be laid upon an approved surface, spread, and struck off to the grade and elevation established.

When more than one JMF is being utilized to produce HMA, the material produced for each JMF shall be placed by separate spreading and compacting equipment. The intermingling of HMA produced from more than one JMF is prohibited. Each strip of HMA placed during a work shift shall conform to a single JMF established for the class of HMA specified unless there is a need to make an adjustment in the JMF. Reference Section 8-20.3(14)C of the Kent Special Provisions for the placement of traffic signal detection loops. 5-04.3(8) Aggregate Acceptance Prior to Incorporation in HMA For HMA accepted by nonstatistical evaluation the aggregate properties of sand equivalent, uncompacted void content and fracture will be evaluated in accordance with Section 3-04. Sampling and testing of aggregates for HMA accepted by commercial evaluation will be at the option of the Engineer. 5-04.3(9) HMA Mixture Acceptance Acceptance of HMA shall be as provided under nonstatistical, or commercial evaluation. Nonstatistical evaluation will be used for the acceptance of HMA unless Commercial Evaluation is specified. Commercial evaluation will be used for Commercial HMA and for other classes of HMA in the following applications: sidewalks, road approaches, ditches, slopes, paths, trails, gores, prelevel, temporary pavement, and pavement repair. Other nonstructural applications of HMA accepted by commercial evaluation shall be as approved by the Engineer. Sampling and testing of HMA accepted by commercial evaluation will be at the option of the Engineer. The mix design will be the initial JMF for the class of HMA. The Contractor may request a change in the JMF. Any adjustments to the JMF will require the approval of the Engineer and may be made in accordance with this section. HMA Tolerances and Adjustments 1. Job Mix Formula Tolerances – The constituents of the mixture at the time of acceptance shall be within tolerance. The tolerance limits will be established as follows: For Asphalt Binder and Air Voids (Va), the acceptance limits are determined by adding the tolerances below to the approved JMF values. These values will also be the Upper Specification Limit (USL) and Lower Specification Limit (LSL) required in Section 1-06.2(2)D2 EVH Slump Repair/Holcomb 5 - 15 November 18, 2021 Project Number: 15-3009 Property Non-Statistical Evaluation Commercial Evaluation Asphalt Binder +/- 0.5%+/-0.7% Air Voids, Va 2.5% min. and 5.5% max N/A For Aggregates in the mixture: a. First, determine preliminary upper and lower acceptance limits by applying the following tolerances to the approved JMF. Aggregate Percent Passing Non-Statistical Evaluation Commercial Evaluation 1”, ¾”, ½”, and 3/8” sieves +/- 6% +/- 8% No. 4 sieve +/-6% +/- 8% No. 8 Sieve +/-6%+/-8% No. 200 sieve +/- 2.0% +/- 3.0% b. Second, adjust the preliminary upper and lower acceptance limits determined from step (a) the minimum amount necessary so that none of the aggregate properties are outside the control points in Section 9-03.8(6). The resulting values will be the upper and lower acceptance limits for aggregates, as well as the USL and LSL required in Section 1-06.2(2)D2. 2. Job Mix Formula Adjustments – An adjustment to the aggregate gradation or asphalt binder content of the JMF requires approval of the Engineer. Adjustments to the JMF will only be considered if the change produces material of equal or better quality and may require the development of a new mix design if the adjustment exceeds the amounts listed below. a. Aggregates –2 percent for the aggregate passing th aggregate passing the No. 8 sieve, and 0.5 percent for the aggregate passing the No. 200 sieve. The adjusted JMF shall be within the range of the control points in Section 9-03.8(6). b. Asphalt Binder Content – The Engineer may order or approve changes to asphalt binder content. The maximum adjustment from the approved mix design for the asphalt binder content shall be 0.3 percent 5-04.3(9)A Vacant 5-04.3(9)B Vacant 5-04.3(9)C Mixture Acceptance – Nonstatistical Evaluation HMA mixture which is accepted by Nonstatistical Evaluation will be evaluated by the Contracting Agency by dividing the HMA tonnage into lots. EVH Slump Repair/Holcomb 5 - 16 November 18, 2021 Project Number: 15-3009 5-04.3(9)C1 Mixture Nonstatistical Evaluation – Lots and Sublots A lot is represented by randomly selected samples of the same mix design that will be tested for acceptance. A lot is defined as the total quantity of material or work produced for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to one day’s production or 800 tons, whichever is less except that the final sublot will be a minimum of 400 tons and may be increased to 1200 tons. All of the test results obtained from the acceptance samples from a given lot shall be evaluated collectively. If the Contractor requests a change to the JMF that is approved, the material produced after the change will be evaluated on the basis of the new JMF for the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the Engineer is satisfied that material conforming to the Specifications can be produced. Sampling and testing for evaluation shall be performed on the frequency of one sample per sublot. 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling Samples for acceptance testing shall be obtained by the Contractor when ordered by the Engineer. The Contractor shall sample the HMA mixture in the presence of the Engineer and in accordance with AASHTO T 168. A minimum of three samples should be taken for each class of HMA placed on a project. If used in a structural application, at least one of the three samples shall to be tested. Sampling and testing HMA in a Structural application where quantities are less than 400 tons is at the discretion of the Engineer. For HMA used in a structural application and with a total project quantity less than 800 tons but more than 400 tons, a minimum of one acceptance test shall be performed. In all cases, a minimum of 3 samples will be obtained at the point of acceptance, a minimum of one of the three samples will be tested for conformance to the JMF: If the test results are found to be within specification requirements, additional testing will be at the Engineer’s discretion. If test results are found not to be within specification requirements, additional testing of the remaining samples to determine a Composite Pay Factor (CPF) shall be performed. 5-04.3(9)C3 Mixture Nonstatistical Evaluation – Acceptance Testing Testing of HMA for compliance of Va will be at the option of the Contracting Agency. If tested, compliance of Va will use WSDOT SOP 731. EVH Slump Repair/Holcomb 5 - 17 November 18, 2021 Project Number: 15-3009 Testing for compliance of asphalt binder content will be by WSDOT FOP for AASHTO T 308. Testing for compliance of gradation will be by FOP for WAQTC T 27/T 11. 5-04.3(9)C4 Mixture Nonstatistical Evaluation – Pay Factors For each lot of material falling outside the tolerance limits in 5-04.3(9), the Contracting Agency will determine a Composite Pay Factor (CPF) using the following price adjustment factors: Table of Price Adjustment Factors Constituent Factor “f” 2 All aggregate passing No. 8 sieve 15 All aggregate passing No. 200 sieve 20 Asphalt binder 40 Air Voids (Va) (where applicable) 20 Each lot of HMA produced under Nonstatistical Evaluation and having all constituents falling within the tolerance limits of the job mix formula shall be accepted at the unit Contract price with no further evaluation. When one or more constituents fall outside the nonstatistical tolerance limits in the Job Mix Formula shown in Table of Price Adjustment Factors, the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The nonstatistical tolerance limits will be used in the calculation of the CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or samples from the Roadway shall be tested to provide a minimum of three sets of results for evaluation. 5-04.3(9)C5 Vacant 5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adjustments For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The total job mix compliance price adjustment will be calculated as the product of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. If a constituent is not measured in accordance with these Specificati EVH Slump Repair/Holcomb 5 - 18 November 18, 2021 Project Number: 15-3009 5-04.3(9)C7 Mixture Nonstatistical Evaluation - Retests The Contractor may request a sublot be retested. To request a retest, the Contractor shall submit a written request within 7 calendar days after the specific test results have been received. A split of the original acceptance sample will be retested. The split of the sample will not be tested with the same tester that ran the original acceptance test. The sample will be tested for a complete gradation analysis, asphalt binder content, and, at the option of the agency, Va. The results of the retest will be used for the acceptance of the HMA in place of the original sublot sample test results. The cost of testing will be deducted from any monies due or that may come due the Contractor under the Contract at the rate of $500 per sample. 5-04.3 (9)D Mixture Acceptance – Commercial Evaluation If sampled and tested, HMA produced under Commercial Evaluation and having all constituents falling within the tolerance limits of the job mix formula shall be accepted at the unit Contract price with no further evaluation. When one or more constituents fall outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The commercial tolerance limits will be used in the calculation of the CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or samples from the street shall be tested to provide a minimum of three sets of results for evaluation. For each lot of HMA mix produced and tested under Commercial Evaluation when the calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. If a constituent is not measured in accordance with these 5-04.3(10) HMA Compaction Acceptance HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a specified compacted course thickness greater than 0.10-foot, shall be compacted to a specified level of relative density. The specified level of relative density shall be a Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density). The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The specified level of density attained will be determined by the evaluation of the density of the pavement. The density of the pavement shall be determined in EVH Slump Repair/Holcomb 5 - 19 November 18, 2021 Project Number: 15-3009 accordance with WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using cores to determine density. Tests for the determination of the pavement density will be taken in accordance with the required procedures for measurement by a nuclear density gauge or roadway cores after completion of the finish rolling. If the Contracting Agency uses a nuclear density gauge to determine density the test procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the mix is placed and prior to opening to traffic. Roadway cores for density may be obtained by either the Contracting Agency or the Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. If the Contract includes the Bid item “Roadway Core” the cores shall be obtained by the Contractor in the presence of the Engineer on the same day the mix is placed and at locations designated by the Engineer. If the Contract does not include the Bid item “Roadway Core” the Contracting Agency may obtain the cores. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the Engineer is satisfied that material conforming to the Specifications can be produced. HMA mixture accepted by commercial evaluation and HMA constructed under conditions other than those listed above shall be compacted on the basis of a test point evaluation of the compaction train. The test point evaluation shall be performed in accordance with instructions from the Engineer. The number of passes with an approved compaction train, required to attain the maximum test point density, shall be used on all subsequent paving. HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling wheel rutting shall be compacted with a pneumatic tire roller unless otherwise approved by the Engineer. Test Results For a sublot that has been tested with a nuclear density gauge that did not meet the minimum of 92 percent of the reference maximum density in a compaction lot with a CPF below 1.00 and thus subject to a price reduction or rejection, the Contractor may request that a core be used for determination of the relative density of the sublot. The relative density of the core will replace the relative density determined by the nuclear density gauge for the sublot and will be used for calculation of the CPF and acceptance of HMA compaction lot. EVH Slump Repair/Holcomb 5 - 20 November 18, 2021 Project Number: 15-3009 When cores are taken by the Contracting Agency at the request of the Contractor, they shall be requested by noon of the next workday after the test results for the sublot have been provided or made available to the Contractor. Core locations shall be outside of wheel paths and as determined by the Engineer. Traffic control shall be provided by the Contractor as requested by the Engineer. Failure by the Contractor to provide the requested traffic control will result in forfeiture of the request for cores. When the CPF for the lot based on the results of the HMA cores is less than 1.00, the cost for the coring will be deducted from any monies due or that may become due the Contractor under the Contract at the rate of $200 per core and the Contractor shall pay for the cost of the traffic control. 5-04.3(10)A HMA Compaction – General Compaction Requirements Compaction shall take place when the mixture is in the proper condition so that no undue displacement, cracking, or shoving occurs. Areas inaccessible to large compaction equipment shall be compacted by other mechanical means. Any HMA that becomes loose, broken, contaminated, shows an excess or deficiency of asphalt, or is in any way defective, shall be removed and replaced with new hot mix that shall be immediately compacted to conform to the surrounding area. The type of rollers to be used and their relative position in the compaction sequence shall generally be the Contractor’s option, provided the specified densities are attained. Unless the Engineer has approved otherwise, rollers shall only be operated in the static mode when the internal temperature of the mix is less than 175°F. Regardless of mix temperature, a roller shall not be operated in a mode that results in checking or cracking of the mat. Rollers shall only be operated in static mode on bridge decks. 5-04.3(10)B HMA Compaction – Cyclic Density Low cyclic density areas are defined as spots or streaks in the pavement that are less than 90 percent of the theoretical maximum density. At the Engineer’s discretion, the Engineer may evaluate the HMA pavement for low cyclic density, and when doing so will follow WSDOT SOP 733. A $500 Cyclic Density Price Adjustment will be assessed for any 500-foot section with two or more density readings below 90 percent of the theoretical maximum density. 5-04.3(10)C Vacant 5-04.3(10)D HMA Nonstatistical Compaction 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots HMA compaction which is accepted by nonstatistical evaluation will be based on acceptance testing performed by the Contracting Agency dividing the project into compaction lots. EVH Slump Repair/Holcomb 5 - 21 November 18, 2021 Project Number: 15-3009 A lot is represented by randomly selected samples of the same mix design that will be tested for acceptance. A lot is defined as the total quantity of material or work produced for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to one day’s production or 400 tons, whichever is less except that the final sublot will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction will be at the rate of 5 tests per sublot per WSDOT T 738. The sublot locations within each density lot will be determined by the Engineer. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the Engineer is satisfied that material conforming to the Specifications can be produced. HMA mixture accepted by commercial evaluation and HMA constructed under conditions other than those listed above shall be compacted on the basis of a test point evaluation of the compaction train. The test point evaluation shall be performed in accordance with instructions from the Engineer. The number of passes with an approved compaction train, required to attain the maximum test point density, shall be used on all subsequent paving. HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the Engineer. 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing The location of the HMA compaction acceptance tests will be randomly selected by the Engineer from within each sublot, with one test per sublot. 5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments For each compaction lot with one or two sublots, having all sublots attain a relative density that is 92 percent of the reference maximum density the HMA shall be accepted at the unit Contract price with no further evaluation. When a sublot does not attain a relative density that is 92 percent of the reference maximum density, the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by either a nuclear moisture-density gauge or cores will be completed as required to provide a minimum of three tests for evaluation. For compaction below the required 92% a Non-Conforming Compaction Factor (NCCF) will be determined. The NCCF equals the algebraic difference of CPF minus 1.00 multiplied by 40 percent. The Compaction Price Adjustment will be calculated as the product of CPF, the quantity EVH Slump Repair/Holcomb 5 - 22 November 18, 2021 Project Number: 15-3009 per ton of mix. 5-04.3(11) Reject Work 5-04.3(11)A Reject Work General Work that is defective or does not conform to Contract requirements shall be rejected. The Contractor may propose, in writing, alternatives to removal and replacement of rejected material. Acceptability of such alternative proposals will be determined at the sole discretion of the Engineer. HMA that has been rejected is subject to the requirements in Section 1-06.2(2) and this specification, and the Contractor shall submit a corrective action proposal to the Engineer for approval. 5-04.3(11)B Rejection by Contractor The Contractor may, prior to sampling, elect to remove any defective material and replace it with new material. Any such new material will be sampled, tested, and evaluated for acceptance. 5-04.3(11)C Rejection Without Testing (Mixture or Compaction) The Engineer may, without sampling, reject any batch, load, or section of Roadway that appears defective. Material rejected before placement shall not be incorporated into the pavement. Any rejected section of Roadway shall be removed. No payment will be made for the rejected materials or the removal of the materials unless the Contractor requests that the rejected material be tested. If the Contractor elects to have the rejected material tested, a minimum of three representative samples will be obtained and tested. Acceptance of rejected material will be based on conformance with the nonstatistical acceptance Specification. If the CPF for the rejected material is less than 0.75, no payment will be made for the rejected material; in addition, the cost of sampling and testing shall be borne by the Contractor. If the CPF is greater than or equal to 0.75, the cost of sampling and testing will be borne by the Contracting Agency. If the material is rejected before placement and the CPF is greater than or equal to 0.75, compensation for the rejected material will be at a CPF of 0.75. If rejection occurs after placement and the CPF is greater than or equal to 0.75, compensation for the rejected material will be at the calculated CPF with an addition of 25 percent of the unit Contract price added for the cost of removal and disposal. 5-04.3(11)D Rejection - A Partial Sublot In addition to the random acceptance sampling and testing, the Engineer may also isolate from a normal sublot any material that is suspected of being defective in relative density, gradation or asphalt binder content. Such isolated material will not include an original sample location. A minimum of three random samples of the suspect material will be obtained and tested. The material will then be EVH Slump Repair/Holcomb 5 - 23 November 18, 2021 Project Number: 15-3009 statistically evaluated as an independent lot in accordance with Section 1-06.2(2). 5-04.3(11)E Rejection - An Entire Sublot An entire sublot that is suspected of being defective may be rejected. When a sublot is rejected a minimum of two additional random samples from this sublot will be obtained. These additional samples and the original sublot will be evaluated as an independent lot in accordance with Section 1-06.2(2). 5-04.3(11)F Rejection - A Lot in Progress The Contractor shall shut down operations and shall not resume HMA placement until such time as the Engineer is satisfied that material conforming to the Specifications can be produced: 1.
