The remainder of the Contract Documents do not have to be submitted. Bidders are warned against making erasures or alterations of any kind to the bid. Bids which contain omissions, erasures or irregularities of any kind may be rejected. Any qualification, addition, limitation or provision attached to or contained in a bid may render the bid non-responsive. No oral, facsimile, telegraphic or telephonic bids or modifications will be considered. B. All bids shall be signed by the Bidder, or the Bidder’s authorized representative. If the bid is made: 1. By an individual, the Bidder's name, signature, and address must be shown; 2.

Therefore, Bidders shall not include such retail sales tax on the Contract Price in their bids or include applicable use taxes in their bids. In accordance with the provisions of this

C01331C19 page 4 of 13 §00100 Rev 12/06/2018 Instructions to Bidders

section, the County will pay the Contractor the Washington State sales tax and/or use tax as appropriate on the contract amount. B.

For example, the County will not add sales tax the Contractor pays on the purchase of tools, machinery, equipment or consumables not integrated into the Work. No adjustment will be made in the amount to be paid by the County under this Contract because of any misunderstanding by or lack of knowledge of the Bidder/Contractor as to liability for, or the amount of, any taxes for which the Bidder/Contractor is liable or responsible by or under this Contract or because of any increases in tax rates imposed by any federal, state or local governments. C. After the Contractor has entered into a contract with the County for the work and submitted a Schedule of Values in a format acceptable to the County, the County and the Contractor will work with the Washington State Department of Revenue to determine which portions of the Work, if any, qualify for the retail sales tax exemption pursuant to RCW 82.04.050. The Contract will be amended to add any retail sales tax and use taxes due, as determined by the Washington State Department of Revenue. D. Washington State sales tax and/or use tax will not be considered for the purposes of calculating the total cost to the County of the bid submitted or determining the lowest Bidder. 2.03 BID GUARANTY A. The bid shall be accompanied by a bid deposit in the amount equal to at least 5% of the Total Bid Price. The bid deposit shall be in one of the following formats and made payable to KING COUNTY: (1) a bid guaranty bond, using either the form provided in §00310 or a form acceptable to the County which contains provisions substantially similar to those in §00310, duly completed by a guaranty company authorized to carry on business in the state of Washington; or (2) a postal money order, a certified check, or cashier's check drawn upon a banking institution with a branch office in the state of Washington. The surety signing the bid guaranty bond shall be registered with the Washington State Insurance Commissioner, and the surety's name shall appear in the current Authorized Insurance Company List in the State of Washington published by the Office of the Insurance Commissioner.

PART 3 — BID EVALUATION AND REJECTION 3.01 OPENING AND POSTPONEMENT OF OPENING A. At the time and place set forth in the Invitation to Bid for the opening and reading of bids, each and every bid (except those which may have been properly withdrawn) received prior to the scheduled closing time for receipt of bids will be publicly opened and read aloud by the King County P&P staff, irrespective of any irregularities or informalities in such bid. The time and place set forth in the Invitation to Bid for opening and reading the bids may only be changed by addendum. B. The County reserves the right to postpone the date and time for opening of bids at any time prior to the opening of bids. C. The time stamp clock located in the P&P’s reception area is the County’s official bid clock for this solicitation. Timeliness of bid submittals will be determined using only this clock. Late bids will not be accepted and returned to the firm submitting as soon as possible. D. Following the bid opening, all bids received will be scanned and uploaded to the online solicitation site identified in paragraph 1.11.B. E. Any document submitted to King County pursuant to this ITB prior to Contract Execution shall be considered a public record under chapter 42.56 RCW (the “Act”) and shall be available for public inspection and copying, unless exempt under the Act. 3.02 MODIFICATION AND WITHDRAWAL OF BIDS A. Modifications or withdrawal of bids already received will be considered only if the requested modification or withdrawal is made prior to the scheduled closing time for the receipt of the bids. All bid modifications or withdrawals must be made in writing, over the signature of the Bidder. 3.03 BID EXTENSION A. The County reserves the right to request Bidders to grant an extension of the effective period of the bid. Such grant shall not be unreasonably withheld. If a Bidder pursues a protest and/or request for reconsideration, its bid is deemed extended until the County executes a contract, or until the protest or request for reconsideration is withdrawn by the Bidder. 3.04 BID ERRORS, INFORMALITIES AND IMMATERIAL IRREGULARITIES A. Prices set forth in the bid will be reviewed by the County for mathematical accuracy. B. The County, in its sole discretion, reserves the right to waive minor bid errors, informalities, and immaterial irregularities when it is in the County’s best interest and does not result in displacement of a low bidder. C. The County reserves the right to correct arithmetical errors and discrepancies between unit prices and extended amount and/or written words or numbers under the following circumstances: 1. The Bidder verifies the error and/or discrepancy; 2. Existence of the arithmetical error and/or discrepancy is ascertainable from the face of the bid; 3. The intended bid is ascertainable from the face of the bid; and 4. Correction of the arithmetical error and/or discrepancy does not result in displacement of a low Bidder.

C01331C19 page 6 of 13 §00100 Rev 12/06/2018 Instructions to Bidders

D. Where the bid is readily susceptible of being interpreted as offering either one of two prices shown on the face of the bid, one of which is low and the other is not, the bid must be rejected. If the evidence of the arithmetical error or discrepancy is clear and convincing the Bidder may be permitted to withdraw its bid. E. In the event a Bidder believes it made an error on its bid, the Bidder shall provide written notice of such claim. The Bidder shall provide to the County supporting evidence for such claim including cost breakdown sheets. The County reserves the right to require the submittal of other bid records or information as the County may deem necessary to evaluate the Bidder’s claim of error, or any error as may be identified by the County during its review of the bid. F. Any review by the County of a bid and/or any review of such a claim of bid error (including supporting evidence) creates no duty or liability on the County to discover any other bid error or mistake, and the sole liability for any bid error or mistake rests with the Bidder or Contractor. 3.05 BID EVALUATION AND RESULTS A. Bids will be evaluated by County to determine which bid is the lowest, responsive bid submitted by a responsible Bidder. B. Within the period after the opening of bids stated in the Form of Bid, the County will either issue a Notice of Selection, reject all bids, or take such other action as may be in its best interest. A written Notice of Selection delivered to the Bidder in person, by U.S. mail or email, will evidence the selection of the lowest responsive and responsible bid. C. Bid results and copies of bids will be posted on the P&P website, generally within 24 hours of bid submission, at https://procurement.kingcounty.gov/procurement_ovr/login.aspx D. Reciprocal Preference for Resident Contractors 1. In accordance with RCW 39.04.380, the County is enforcing a Reciprocal Preference for Resident Contractors. Any public works bid received from a Nonresident Contractor from a state that provides a percentage bidding preference, a comparable percentage disadvantage must be applied to the bid of that Nonresident Contractor. States that currently provide bidding percentage preferences to resident contractors are: Alaska, Nevada, New Mexico and Wyoming. 2. A “Nonresident Contractor” is a contractor that: (a) is from a state that provides a percentage bid preference to its resident contractors bidding on public works contracts; and (b) at the time of bidding on a public works project, does not have a physical office located in Washington. 3. The state of residence for a Nonresident Contractor is the state in which the contractor was incorporated or, if not a corporation, the state where the contractor’s business entity was formed. 4. All Nonresident Contractors will be evaluated by the County for an out of state percentage bidding preference. If the state of the Nonresident Contractor provides a contractor percentage bidding preference, a Comparable Percentage Disadvantage (“CPD”) will be applied, by the County, to the Nonresident Contractor’s Total Bid Price during bid evaluation. The CPD is the percentage

C01331C19 page 7 of 13 §00100 Rev 12/06/2018 Instructions to Bidders

bidding preference advantage, provided by the Nonresident Contractor’s home state. 5. For the purpose of determining the low bidder, the County shall multiply the Nonresident Contractor’s Total Bid Price by the CPD. The CPD shall be added to the Nonresident Contractor’s Total Bid Price which equates to the Nonresident Contractor’s Disadvantage Total Bid. This Nonresident Contractor’s Disadvantage Total Bid shall be compared to the other bidder(s) Total Bid Price(s) for the solicitation and the bidder with the lowest total bid shall be the low bidder for this solicitation. See example below. EXAMPLE: Alaska Nonresident Contractor’s Total Bid Price $100,000 Multiplied by the Alaska CPD x 0.05 Alaska CPD Total $ 5,000

Alaska Nonresident Contractor’s Total Bid Price +$100,000 Alaska CPD Total $ 5,000 Nonresident Contractor’s Disadvantage Total Bid $105,000*

* NOTE: If the Nonresident Contractor’s Disadvantage Total Bid is lower than the other bidder(s) Total Bid Price(s), the Alaska Nonresident Contractor will be the low bidder, and if found responsible, will be awarded a contract for the Total Bid Price of $100,000. If the Nonresident Contractor’s Disadvantage Total Bid is higher than the other bidder(s) Total Bid Price(s), the bidder with the lowest Total Bid Price, if found responsible, will be awarded a contract for their Total Bid Price. 3.06 QUALIFICATIONS OF BIDDER A. In accordance with RCW 39.04.350 the low responsive bidder shall demonstrate, to the satisfaction of the County, that the Bidder and/or its project team are responsible and qualified to perform the Work under this Contract. Project examples, submitted with the Qualifications Information, shall have been substantially completed by the time of bid submittal. Section 00440, Responsibility Detail Form of the Contract Documents contains the mandatory and, if any supplemental criteria, for Bidder responsibility. The Bidder shall promptly prepare, complete, and submit the required information to the County within the time specified. In the event a Bidder fails to provide qualification information as required in §00440, or other information requested by the County, the Bidder may be rejected as not responsible. B. Following determination of the low responsive Bidder, the County may request the following: 1. W-9 Request for Taxpayer Identification Number (King County Substitute W-9). 2. Billing Information - current remittance information (location where King County is to send payments): a) Remit-to Address: b) Contact Name: c) Contact Phone #: d) Contact Fax #: e) Contact Email:

C01331C19 page 8 of 13 §00100 Rev 12/06/2018 Instructions to Bidders

E. Failure to Comply with the Apprenticeship Requirements. 1. Unless otherwise determined by the Administrator, in accordance with the standards established in King County Code 12.16.150-180, failure by a Contractor to comply with the Apprenticeship Program requirements shall be deemed a breach of Contract for which the County shall be entitled to all remedies allowed by law and under this contract. In the event the Contractor and/or its subcontractors fail to comply with the Apprenticeship Program requirements, King County may withhold progress payments, assess liquidated damages, and seek any other remedy allowed by law.

C01331C19 page 12 of 13 §00120 Rev. 01/15/2019 WO debarred from being awarded King County contracts for a period not to exceed two years from the date of the Notice of Completion and Final Acceptance of this contract. The debarment procedures shall ensue as specified in King County Code 12.16.115. The following shall be considered in any debarment proceedings: a. The Contractor’s degree of compliance with the apprenticeship requirements of current and previous King County contracts. b. The Contractor’s Best Efforts to meet the apprenticeship requirement. c. The Contractor’s contacts with approved apprenticeship training programs, such as ANEW, Apprenticeship Opportunities Project, the Seattle Vocational Institute, and the Washington State Apprenticeship and Training Council. d. Neither the provisions of any collective bargaining agreement, nor the failure by a labor union or referral agency with whom the contractor or subcontractor have a collective bargaining agreement, to refer workers shall excuse the contractor's obligation to comply with the Apprentice requirements established for this contract in accordance with King County Code 12.16.150- 180. F. Liquidated Damages. This Contract hereby incorporates by reference King County Code 12.16 150-180 (King County Apprenticeship Program). The unexcused failure of the Contractor or any subcontractor to comply with any of the requirements of K.C.C. 12.16 150-180 shall be a breach of contract. The purpose of King County’s Apprenticeship Program is to provide the region with a well-trained work force. King County in general, and its Apprenticeship Program in particular, are damaged when Apprentice participation and training does not occur at the required levels. Because the actual amount of such damage is not reasonably calculable, the parties agree and stipulate that liquidated damages equal to the prevailing wage rate, including benefits, for 1st year general laborer Apprentice at the time of contract execution shall exist, for every short fall hour of Apprentice participation, as provided in Section 00700. This will fairly compensate King County for resulting delays in carrying out the purpose of the Apprenticeship Program, the costs of meeting utilization Requirements through additional contracts, the administrative costs of investigation and enforcement, and other damages and costs caused by the violation. The following example is for informational purposes only: For this example assume the labor rate is $20.98 Total labor hours subject the apprenticeship requirement 10,000 Total labor hours to meet the apprenticeship requirement 1,500 (10,000 X 15% = 1,500) Actual Apprentice hours reported: 1,000. Shortfall in Apprentice hours: 500 Liquidated damages: $10,490.00 (500 hours X $20.98 = $10,490.00)

If the scope of Work is significantly expanded, or if the aggregate limits on any of the Contractor’s policies are eroded, the County may require Contractor to obtain additional coverage or reinstate eroded coverage. If the need for additional coverage is due to the fault of the Contractor or any of its Subcontractors, the Contractor shall be responsible for the cost of such additional coverage or any of its Subcontractors coverage. The Contractor shall provide proof of additional insurance required because of changed Work (Change Orders). C. If the Contractor is required to correct damaged, defective or incomplete Work after Final Acceptance, it shall obtain at its own expense such insurance coverage as is required by the Contract, for the construction period.

ARTICLE 4: ADMINISTRATION OF THE CONTRACT 4.0 TIME OF ESSENCE A. All time requirements set forth in the Contract Documents, including the Work Order, are of the essence.

C01331C19 page 22 of 48 STDWO §00700 01/30/2015 General Terms and Conditions

4.1 WORK PROGRESS A. The Contractor shall: 1. Prosecute the Work diligently with adequate forces; 2. Plan, coordinate, and layout the Work in advance so as to avoid delay; 3. Timely perform and complete each Work Order to achieve both Substantial Completion and Final Completion of a Work Order, and; 4. Complete all Contract close out activities in accordance with all applicable Contract requirements to achieve Final Acceptance as required by the Contract. 4.2 SCHEDULE OF VALUES A. Each Work Order may have a Schedule of Values. Only upon the request of the County, the Contractor shall submit to the County at the time specified in the Work Order a detailed Schedule of Values which identifies the various activities of the Work and their values and quantities, including the overhead and profit for each activity. The Contractor warrants that the values identified in its Schedule of Values accurately reflect the value of each work activity. The Schedule of Values shall be used as a basis for calculating all Progress Payments. Payment for Work shall be made only for and in accordance with those activities identified in the Schedule of Values. B. If a Schedule of Values is requested, the Contractor shall not be entitled to, nor shall the County be required to make, payment for any Work until the Schedule of Values has been accepted by the County. Such acceptance shall not be unreasonably withheld. C. The County shall review and accept the Schedule of Values or provide the Contractor with a written explanation of why the Schedule of Values was not acceptable. The County’s acceptance of the Schedule of Values shall not relieve the Contractor from its sole responsibility for the accuracy of the Schedule of Values and its compliance with all Contract requirements. The Contractor shall revise the Schedule of Values as necessary to accurately reflect Change Orders to a Work Order. D. When required, each Application for Payment shall include a current status of the Schedule of Values. No Application for Payment will be considered until the current status of the Schedule of Values has been submitted and accepted. E. The activities which the Contractor identifies within its Schedule of Values shall be specifically referenced within, and conform and be consistent with the activities set forth within the Project Schedule. F. The County also reserves the right to direct the Contractor to provide a Schedule of Values to assist the Parties to negotiate and execute a Work Order. 4.3 WORK ORDER SCHEDULE A.

C01331C19 page 23 of 48 STDWO §00700 01/30/2015 General Terms and Conditions

Final Completion of a Work Order within the Work Order Time, and meet all the requirements as maybe set forth more particularly in the Project Documents of the Work Order. B. The Work Order Schedule shall be prepared in the format as specified by the Work Order Project Manager. C. The County shall review the Work Order Schedule and provide the Contractor with written comments. The County will review the Work Order Schedule only to determine whether the Schedule meets the requirements established by the Work Order Project Manager. To the extent the Work Order Schedule does not meet such requirements the Contractor shall revise the Schedule to make it compliant. D. By reviewing the Schedule and providing written comments, the County is not approving or adopting the Contractor’s plan, schedule, means, methods, techniques, sequences, or procedures required to perform the Work. Review and comment by the County of the Schedule shall not relieve the Contractor from the sole responsibility for the accuracy of a Work Order Schedule, and its compliance with all Contract requirements, and its responsibility to meet all required Work Order completion dates. Failure by the County to indicate items on the Schedule that do not conform to the requirements shall not alter or waive the requirements or relieve the Contractor from complying with all Contract requirements. E. If a Work Order Schedule is requested by the County, the Contractor shall not be entitled to, nor shall the County be required to make payment for that Work Order until the Schedule complies with all requirements. F. The Contractor shall schedule the Work so that the Work Order is completed on time. If the Contractor attempts to perform the Work in less than the Work Order Time no additional compensation for any delays attributable to the County or any acceleration will be owed to the Contractor if the Contractor fails to achieve the earlier completion date. G. If a Work Order Schedule is required, the Contractor shall regularly enter the actual progress of the Work and Work Order Time extensions approved by the County on the Work Order’s Schedule. Updated Schedules shall reflect actual progress and completion within the Work Order Time and shall be provided to the County with each Application for Payment in hard copy and/or electronic format as required by the Work Order Project Manager. Applications for Progress Payments will not be considered by the County and the Contractor shall not be paid until the Contractor complies with these requirements. The most recently updated Project Schedule shall be used to assist the County in verifying the appropriate payment. H. If, in the opinion of the County, the Contractor falls behind in its progress of the Work due to acts or omissions of the Contractor or its Subcontractors, the County may direct the Contractor to take all necessary steps to improve its progress and bring its progress back in-line with the accepted Work Order Schedule, without additional cost to the County. In this circumstance the Contractor shall, as necessary, increase the number of shifts, overtime operations, and/or days of work, both on and off the Site, and submit for acceptance any supplementary schedule or schedules as the County deems necessary to demonstrate how the accepted rate of progress will be regained. Failure of the Contractor to comply with the requirements under these provisions shall be grounds for a determination by the County that the Contractor is not prosecuting the Work with sufficient diligence to ensure completion

C01331C19 page 24 of 48 STDWO §00700 01/30/2015 General Terms and Conditions

within the time specified in the Contract. Upon making this determination, the County may pursue any right it has under the law or the Contract, including but not limited to default termination. 4.4 SUBMITTALS A. The Contractor shall not perform any portion of the Work requiring submittals until the submittals have been reviewed and returned by the County with one of the following annotations: (1) no exceptions taken or (2) note markings with no exceptions taken.

The Contractor shall provide submittals with reasonable promptness and in such sequence as to facilitate the timely completion of the Work Order. The Contractor shall prepare and keep current, for review by the County, a schedule of submittals which is coordinated with the Contractor’s Work Order Schedule and allows the County reasonable time for review. D. The County shall review the Contractor’s submittals and respond in writing with reasonable promptness. Unless otherwise agreed, no delay to the Contractor’s Work shall be attributable to the failure by the County to respond to a submittal until 14 days after the submittal is received by the County, and then only if failure by the County to respond is unreasonable and affects Work on the Critical Path for Substantial Completion or Final Completion of the Work Order. E. The County shall review the Contractor’s submittals only for conformance with the design of the Work and compliance with the Work Order. Review of the submittals are not conducted to verify the accuracy of dimensions, quantities, or calculations, the performance of materials, systems, or equipment, or construction means, methods, techniques, sequences, or procedures, all of which remain the Contractor’s responsibility. Failure by the County to take exception to a submittal or note any errors or omissions in a submittal shall not relieve the Contractor from any duty, including its responsibility for errors or omissions in submittals, its duty to make Submittals and duty to perform the Work according to the requirements of the Contract. The County’s review of a submittal shall not alter or waive the requirements of the Contract unless the County has issued prior written approval of such change or alteration of the Contract requirements. F. The Contractor’s failure to identify any error, deviation, or omission and subsequent acceptance of the submittal by the County shall not relieve the Contractor from complying with the Contract requirements. 4.5 REQUESTS FOR INFORMATION A.

C01331C19 page 25 of 48 STDWO §00700 01/30/2015 General Terms and Conditions

Contract, the Contractor shall promptly submit a Request For Information (“RFI”) and, unless otherwise directed, shall not proceed with the affected Work until the County has responded to the RFI. The Contractor shall plan its work in an efficient manner so as to allow for timely responses to RFIs. B. RFIs shall only be submitted by the Contractor on a RFI Form provided by the County or in a form acceptable to the County. The Contractor shall clearly and concisely set forth the issue for which clarification or interpretation is sought and why a response is needed by the County. In the RFI the Contractor shall set forth its own interpretation or understanding of the requirement along with reasons why it reached such an understanding. C. Unless otherwise stated within a Work Order, the County shall respond in writing within 10 days of receipt to the Contractor’s RFI. No delay to the Contractor’s work or damages to the Contractor shall be attributable to the failure by the County to respond to the RFI until 10 days after the County’s receipt of the RFI, and then only if the failure by the County to respond is unreasonable and affects the Work on the Critical Path for Substantial Completion or Final Completion of the Work Order. D. The County’s response to a RFI shall not be considered a change to the Contract or Work Order requirements. To the extent the Contractor believes that the County’s response to the RFI constitutes changed work impacting Work Order Time or Work Order Price, the Contractor shall submit a Request for Change Order to the Work Order to the County’s Project Representative and Work Order Project Manager. If it is denied, the Contractor shall file a claim in accordance with provision 5.3, Contractor Claims. 4.6 TESTS, INSPECTIONS, AND ACCESS TO THE WORK A. The Contractor shall document and maintain an adequate testing and inspection program and perform such tests and inspections as are necessary or required to ensure that the Work conforms to the requirements of the Contract. The Contractor shall maintain all documentation related to testing and inspection and make such documentation available to the County at its request.

Contractor shall maintain complete inspection records and make them available to County upon request. B. The Contractor shall cooperate with the County in the performance of any tests and inspections of the Work. The Contractor has the duty to coordinate all tests and inspections in a manner that does not negatively impact Contractor’s compliance with the Contract. C.

C01331C19 page 26 of 48 STDWO §00700 01/30/2015 General Terms and Conditions

Work Order or if any non-compliance was not the direct cause of the Contractor or a Subcontractor, the County will pay the costs associated with this inspection, testing, uncovering and recovering of the Work. If it is determined that the actions of the Contractor or its Subcontractor created the non-compliance condition, the Contractor shall bear such costs as well as all costs of correction. D. The County may, at any reasonable time and at its own cost, conduct inspections and tests as it deems necessary to ensure that the Work is in accordance with the Contract. The County shall promptly notify the Contractor if an inspection or test reveals that the Work is not in accordance with the Contract.

Inspectors are not authorized to change any term or condition of the Contract. F. Contractor shall promptly furnish, without additional charge, all facilities, labor, material and equipment reasonably needed for performing such safe and convenient inspections and tests as may be required by County. County may charge Contractor any additional cost of inspection or testing when Work is not ready at the time specified by Contractor for inspection or testing, or when prior rejection makes re-inspection or retest necessary. County shall perform its inspections and tests in a manner that will cause no undue delay in the Work. 4.7 CORRECTION OF WORK OR DAMAGED PROPERTY A. If the County determines that material, equipment, workmanship, or Work proposed for, or incorporated into the Work, does not meet the Contract requirements or fails to perform satisfactorily, the County shall have the right to reject such Work by giving the Contractor written notice that such Work is either defective or non- conforming. The County, at its option, shall require the Contractor, within a designated time period as set forth by the County, to either: (1) promptly repair, replace or correct all Work not performed in accordance with the Contract at no cost to the County; or (2) provide a suitable corrective action plan at no cost to the County and once accepted by the County, the Contractor shall implement the corrective action plan at no cost to the County.

C. If the Contractor does not repair, replace or correct and/or remove rejected Work or repair damaged property as required by the County, the County or County’s designee may repair, replace or correct and/or remove it and deduct the cost of such effort from any payment due the Contractor. Under this provision, the County reserves the right to make use of the Contractor’s plant and equipment for this repair, replacement, correction or removed Work. If the remaining payments due the Contractor are not sufficient to cover the County’s cost of remedying the rejected work, the Contractor shall pay the difference to the County. D. The County may elect to retain defective or non-conforming Work if the County determines removal of such Work is impractical or will create conditions which are dangerous or undesirable. Just and reasonable value for such defective or non- conforming Work will be determined by the County and appropriate deductions will be made in the payments due or to become due to the Contractor. The County’s exercise of the rights under this provision shall be without prejudice to any other remedy the County may have, and shall not constitute a termination of the Contract. E.

The Contractor shall maintain its progress with the Work. 6. Failure to submit a timely and complete Request for Change Order according to the provisions set forth herein shall constitute a waiver of the Contractor’s right to receive any additional time, money, damages or any other relief as a result of any event, occurrence, Direction or condition alleged by the Contractor. B. Differing Site Conditions 1. The Contractor shall immediately, and before the conditions are disturbed give written notice to the County of Differing Site Conditions, which are defined as: (a) subsurface or latent physical conditions at the Site which differ materially from those indicated in the Contract and/or Work Order, or (b) unknown physical conditions at the Site, of an unusual nature which differ materially from those ordinarily encountered and generally recognized as inherent in the construction activities of the character provided for in the Contract and/or Work Order. 2.

Failure by the Contractor to provide either: (a) immediate notice; or (b) the detailed description of impacts within 7 days as described above shall constitute a waiver of the Contractor’s right to an adjustment to Work Order’s Time or Price as a result of the Differing Site Condition. The Contractor shall be responsible for any and all costs or damages, incurred by the County, resulting from the Contractor’s failure to provide appropriate notice and/or a detailed description of impacts. 4.

When paving roadways, do not place concrete in an adjacent lane sooner than 72 hours after finishing of the previous lane. Operate mixers and trucks on the subgrade or on the shoulder adjacent to the lane being paved. Do not use newly paved lanes to operate mixers, trucks or other construction equipment unless the concrete pavement meets requirements set forth in Paragraph 3.15 of this Section. h. Construct a protective ramp at the pavement edge where vehicles are driven on and off the pavement. Leave the forms on the outside edge of the first lane at turnouts until the pavement is opened to traffic. i. When tie bars are specified, place the tie bars before the concrete is struck off during the last pass with the strike-off screed. Protect the tie bars from traffic by bending down and back against the side form. Straighten the tie bars prior to placing concrete for the adjacent lane. j. When using unimproved areas or roadways, shoulders, or subgrade for work, keep them adequately dampened to prevent the accumulation of dust upon the freshly placed concrete. k. When integral curbs are required, place fresh concrete for the curbs at such time as will enable the top section of the curb to be consolidated, finished, and bonded to the pavement slab while the concrete is plastic. l. Construct concrete pavement panels as specified and as shown on the Drawings and in the submittal documents reviewed by the Project Representative. Panels larger than the size shown on the Drawings shall not be acceptable, unless approved by the Project Representative in writing prior to placing concrete. 2. Concrete Placement around Through-Joints: a. Place concrete around through-joints so that the joint assembly is not disturbed and remains in a straight line, perpendicular to the base course. Vibrate the concrete along the entire length of the joint to consolidate. Do not leave rock pockets anywhere at the joint. Repair rock pockets if they develop. 3. Concrete Placement with Wire Mesh or Reinforcing Steel: a. When wire mesh is called for on the Drawings, place concrete in two courses. Strike off the first course at the elevation established for the wire mesh. Immediately prior to placing the wire mesh, bring the concrete to a fairly even surface by means of a template conforming to the depth of the wire mesh. Place the wire mesh on the bottom course before the concrete attains initials set. Do not allow more than 45 minutes to elapse between mixing of the first course and placement of the second course. b. When reinforcing steel is called for on the Drawings, and concrete is placed in one lift, secure the steel in the required position in compliance with the requirements of 3.06 B., above. Prior to placing concrete, demonstrate to the Project Representative that the steel is secured and at the required locations in the slab. c. Prior to placing concrete, demonstrate to the Project Representative that the wire mesh and reinforcing steel are free of dirt, mill scale, oil, grease, or other foreign material that may impair bond. If the concrete is placed in two courses, where

C01331C19 11 32 13 13 Portland Cement Concrete Paving wire mesh is used, remove dirt, sand, or dust which collects on the base course before the top course is placed. d. Maintain wire mesh and reinforcing in the proper position during concrete placement operations. 4. Concrete Placement in Hot or Cold Weather: a. In hot weather (more than 80 degrees F), place concrete in accordance with ACI 305. b. In cold weather (less than 50 degrees F), place concrete in accordance with ACI 306.

E. Consolidating Concrete: 1. In general, consolidate concrete in accordance with ACI 309. 2. If proper consolidation is not being achieved or the Contractor fails to comply with provisions of the specified consolidation procedures, the Project Representative will suspend concrete paving operations. 3. Consolidate concrete during placing operations so that concrete is thoroughly worked around reinforcement and other embedded items and into corners. Deposit and consolidate concrete in a continuous operation, within limits of construction joints. 4. Consolidate the concrete by means of high frequency mechanical internal vibrators. The number of vibrators and size of vibrator heads shall be in accordance with the vibrator manufacturer's recommendations for the conditions of the work and as approved by the Project Representative. Provide a minimum of two 2-1/2-inch diameter vibrators with a minimum of 9,000 impulses per minute, with an amplitude of not less than 0.040-inch, to a maximum of 12,000 impulses per minute, with amplitude of not less than 0.075-inch. Keep spare vibrators of each size and type at the site during concrete placing operations. 5. Insert and withdraw vibrators vertically at 18 to 24 inches apart. At each insertion, the duration shall be sufficient to consolidate the concrete but not enough to cause segregation or bleeding. Thoroughly work concrete around into the corners of forms, eliminating air or aggregate pockets. If, during placing operation, there is a delay of more than 15 minutes, vibrate the previous lift just prior to placing new concrete. Use and type of vibrator shall comply with ACI 309. 6. Use of vibrating screed will be permitted subject to Project Representative's approval, which shall be based upon a test over an appropriate section of pavement where the capabilities of the screed to satisfactorily compact and strike off the concrete to the established grade and section shall be demonstrated. If use of the vibrating screed is approved, observe the following procedures: a. Concrete shall be uniformly distributed between the forms and shall then be compacted and screeded to the level of the top of the forms by means of the vibrating screed. Supplemental compaction by mechanical vibration of the concrete adjacent to the forms will be required if the concrete cannot otherwise be adequately compacted. b. Operate the vibrating screed over the freshly placed concrete in successive passes only a sufficient number of times to obtain maximum compaction. Over vibration of the concrete, resulting in an excess of mortar at the surface of the pavement, will not be permitted. c. After the final passages of the vibrating screed, the surface of the concrete shall be at the established pavement grade and cross section and shall be sufficiently smooth as to require only a very moderate amount of hand finishing for smoothness to meet approval of the Project Representative.

C01331C19 12 32 13 13 Portland Cement Concrete Paving 3.08 SURFACE SMOOTHNESS

A. Bring the pavement surface to the final level with a straightedge and strikeoff. Use bull floats or darbies to smooth the surface, leaving it free of humps or hollows. Do not sprinkle water on the plastic surface. Do not disturb the surfaces prior to beginning finishing operations.

B. Check for surface smoothness shall be checked with a straightedge 10 feet long, mounted to a long handle to permit operation from outside the pavement. Place the straightedge on the surface of the pavement, parallel to the centerline, and at intervals of no more than 5 feet across the full pavement width. The surface of the pavement shall not vary from a true surface by more than 1/8-inch in 10 feet.

C. The transverse slope of the finished pavement shall be uniform to a degree such that no variation greater than 1/4-inch is present when tested with a 10-foot straight edge laid in a direction perpendicular to the centerline.

D. In no case shall the grade in the gutter be such that it will allow ponding of water. If the surface smoothness of the pavement after curing is found to exceed the tolerance permitted, the high spots shall be ground until they meet tolerance. If the surface tolerance cannot be met satisfactorily by grinding, remove and replace the pavement to conform with the requirements of the Contract Document.

3.09 SURFACE FINISH

A. Consolidate the pavement and finish the surfaces true to grade and cross-section by hand or machine finishing methods. On vertical curves and at irregular intersections, use modified tools as necessary to secure a smooth, uniform contour and surface.

B. Hand Finishing: After the concrete has been struck off and consolidated, smooth it by longitudinal floating. Move ahead in successive advances of not more than 1/2 the length of the float. Continue floating until irregularities are removed. Follow compaction of the concrete with longitudinal floating by no less than 30 feet. Remove free water off the pavement with the float or other suitable tool. After floating, scrape the surface with a grout rod at least 10 feet in length, having a long handle for operating at the edge of the pavement. Operate the grout rod to correct irregularities in the pavement surface and remove water and laitance.

C. Machine Finishing: 1. The finishing machine shall be of a type approved by the Project Representative. The machine shall be adjustable to both crown and plane of the finished pavement surface. The screed shall oscillate longitudinally during its travel transversely across the pavement. It shall be operated in the forward direction so that the screed will pass over the same section of pavement at least 2 times during its transverse travel. 2. Move the finishing machine over the pavement as many times as necessary to give the pavement a smooth even textured surface, conforming to the exact crown and cross section specified on the Drawings. The floating shall not be considered complete until free water is removed from the surface. Perform the finishing operations at a time and over such lengths of the pavement surface as existing conditions dictate.

C01331C19 13 32 13 13 Portland Cement Concrete Paving D. Edging: Perform edging before the final texturing and before the concrete has taken the final set. Form a 1/2-inch radius at pavement edges. Form other radii as shown on the Drawings.

E. Roadways Final Texturing: After edging, give the pavement surface a uniform, gritty texture true to grade and cross section. Accomplish the final texturing by the method described below, or by other means acceptable to the Project Representative to achieve the specified surface texture. 1. Give the pavement a final finish surface by texturing with a comb perpendicular to the centerline of the pavement. Use comb that produces striations approximately 0.015-foot in depth at approximately 1/2-inch spacing in the fresh concrete. The actual nominal depth limits of the striations will be determined in the field by the Project Representative. Construct a test section to demonstrate acceptable performance of the striation equipment. 2. Operate the comb mechanically, either singly or in gangs with several placed end to end. Finishing shall take place with the elements of the comb as nearly perpendicular to the concrete surface as is practical, to eliminate dragging the mortar. 3. If the pavement has a raised curb without a formed concrete gutter, end the texturing 2 feet from the curb line. Hand-work this 2-foot untextured strip to form a light brush finish. Give the top of the curb a broom finish.

F. Sidewalks: Screed and slope the concrete surfaces as shown on the Drawings. After screeding, give the surfaces a coarse transverse scored texture by drawing a broom or burlap belt across the surface. Round edges to a radius of 1/2-inch. Grove joints to a radius and depth of 1/4-inch.

3.10 JOINTS

A. General: 1. Use the type of joints and spacing shown on the Drawings. Follow the plan and schedule outlined in the submittal document reviewed by the Project Representative. 2. Where the spacing between joints cannot be set in even multiples of the maximum specified distance, shorten the last several spaces approaching a construction or an isolation joint. 3. When paving adjacent to existing pavement, place new joints matching existing joint locations. Where the existing joint spacing is greater than the spacing shown on the Drawings, construct intermediate joints. 4. For intersections and other irregular areas, arrange in accordance with PCA or TSS standards for intersection patterns, or as directed by the Project Representative. The area of irregular pattern formed by contraction joints in intersections shall not exceed 225 square feet and the greatest dimensions thereof shall not exceed 16 feet. 5. When paving a second lane adjacent to the previously paved lane, match joints with the former, except on curves where the least dimension between transverse joints of the resultant panel would be less than 80 percent of the maximum allowable distance between joints. 6. When uncontrolled cracks develop on a given pavement lane, match them as nearly as possible with joints constructed on the adjacent lanes. Should the uncontrolled cracks in the existing paved lane be too frequent or in random locations, and impossible to match with a uniform spacing in the second lane, the two lanes shall be completely separated by 3/8-inch joint material extending from the surface to 1-inch below the bottom of the concrete being placed. Reinforcing steel, or other approved

C01331C19 14 32 13 13 Portland Cement Concrete Paving joint material, may be required by the Project Representative in lieu of the 3/8-inch joint material to control reflection cracks in the new pavement. 7. Continue joints across integral or doweled curbs by placing premolded joint filler material transversely across the full section of the curbs, in true alignment with the pavement joint, and perpendicular to the pavement grade.

B. Formed Control Joints: 1. Construct by embedding a 3/8-inch thick preformed joint material. The depth of the formed joints shall be no less than 1/4 of the pavement thickness. The filler shall be cut to the exact section of the joint. The length of the premolded joint filler shall extend to within 1/4-inch of both edges of any panel. 2. Transverse control joints (dummy joints) shall be placed after compaction and finishing of concrete have been completed and before initial set. A groove shall be cut into the surface at the location of the joint, using a tool provided with stops to prevent cutting the groove deeper than the planned depth of the joint filler. The joint filler shall then be forced into the groove until the top is flush with the pavement surface, with a deviation of not more than 1/8-inch below the surface. The joint filler shall be perpendicular to the surface and always in a straight line. 3. After the joint filler has been imbedded in the concrete, the surface of the pavement shall be finished against the filler strip with hand floats to restore the surface finish. While performing this operation, the filler strip shall be maintained in a perpendicular position, true to alignment. After finishing the entire area the joint shall be true to grade and smoothness without any irregularities.

C. Sawed Control Joints: 1. Before placing concrete, satisfy the Project Representative that equipment, materials and incidentals necessary to accomplish the sawing of joints are at the job site and will remain there, continuously, until the completion of joint sawing work. Demonstrate that a sufficient number of sawing units and blades, as needed to accomplish the sawing before random cracking develops, is available at the site. Demonstrate that standby equipment and artificial lighting are available as necessary to ensure continuous sawing as specified, regardless of equipment breakdowns or natural lighting conditions. 2. Construct joints by sawing a uniform, 1/8-inch wide vertical groove, of the depth shown on the Drawings, in the hardened concrete before random cracks develop. Proceed as soon as saw cutting can be made without undue raveling of concrete, taking into consideration the maximum size of the coarse aggregate and in accordance with the schedule established in the submittal document reviewed by the Project Representative. Saw transverse control joints before sawing the longitudinal joints. Saw joints at the intervals shown on the Drawings or at a maximum of 12-foot intervals, unless other spacing has been pre-approved by the Project Representative. Saw intermediate joints thereafter. Minimum 3 days after placing the concrete, expand the top portion of the original cut to the width and depth shown on the Drawings. 3. The Project Representative will monitor compliance with the schedule established for sawing contraction joints. Scheduling for the sawing of joints that results in premature or uncontrolled cracking shall be revised immediately, under the direction of the Project Representative. Revise by adjusting the time interval between placing of concrete and the sawing of joints. After the proper schedule has been determined, proceed with the sawing as a continuous operation until all joints have been completed.

C01331C19 15 32 13 13 Portland Cement Concrete Paving 4. Where curing membrane is used, re-spray the area disturbed by sawing of joints immediately upon completion of the sawing operation. Exercise care to prevent the curing compound from getting into the joint grooves: joint sealing compound will not adhere to concrete if curing compound is present. 5. The Project Representative may require the installation, and designate the location, of formed control joints if necessary to prevent uncontrolled concrete cracking from occurring before the pavement panels can be sawed. 6. Repair random cracking by working the entire length of each crack as required to produce a typical control joint as shown on the Drawings.

D. Isolation (Through) Joints: 1. Before placing concrete, satisfy the Project Representative that equipment, materials and incidentals necessary to accomplish the sawing of joints is at the job site and will remain there, continuously, until the completion of joint sawing work. Demonstrate that a sufficient number of sawing units and blades, as needed to accomplish the sawing before random cracking develops, is available at the site. Demonstrate that standby equipment and artificial lighting are available as necessary to ensure continuous sawing as specified, regardless of equipment breakdowns or natural lighting conditions. 2. Construct isolation (through) joints with full depth, premolded, expansion joint filler material as shown on the Drawings and as specified in this Section. 3. Hold the joint filler material accurately in place during the placing and finishing of the concrete using a bulkhead, a hold, a metal cap or other method acceptable to the Project Representative. The finished joint shall be perpendicular to the paved surface and the holder shall be in place long enough to prevent sagging of the material, especially on surfaces with steep grades. 4. Place a wood filler strip or metal cap on the top of the premolded joint filler to form the top of the joint as shown on the Drawings. Keep in place until after the concrete is sufficiently set to resist sloughing into the groove. Staple the joint filler together at the ends to preserve continuity.

E. Construction Joints: 1. Place construction joints as shown on the Drawings, as established in the joint layout submittal document reviewed by the Project Representative, and wherever the placing of concrete is suspended for more than 30 minutes. 2. Select the type of joint from those shown on the Drawings that fit the joining conditions found in the field such as transverse, longitudinal, different slab thickness, etc. 3. Make transverse construction joints by placing a header board transversely across the subgrade. Keep the header board in place until the paving is resumed. 4. Make longitudinal construction joints by placing a header board with an attached wedge shaped strip of wood or preformed plastic to form a key in the concrete. Keep the header board in place until the paving is resumed.

3.11 JOINT SEALING

A. NOT USED

C01331C19 16 32 13 13 Portland Cement Concrete Paving 3.12 CONCRETE CURING

A. General: 1. Concrete placement will not be permitted unless curing materials are on the job site and ready for immediate application. Upon failure to comply with provisions of the curing procedures specified the Project Representative will suspend all concrete operations. Operations thereafter will not be resumed until the Project Representative is satisfied that all aspects of the work will conform to the specified procedures. 2. Cover and cure the entire surface of the newly placed concrete immediately after the finishing operations have been completed and as soon as the Project Representative determines that marring of the concrete will not occur. Cure surfaces paved with concrete classes ES-1 and ES-2 as recommended by the concrete mix supplier. 3. Regardless of the curing method used, maintain the curing protection and protect from damage from any cause for at least the length of time listed below for the various types of mixes, or until the pavement is opened to traffic, whichever is longer. Length of time for mixes C-1 and C-5 shall be exclusive of the day the concrete is placed.

Mixes with Type I Portland cement: 7 days Mixes with Type III Portland cement: 3 days Classes ES-1 and ES-2 with Type III Portland cement: as recommended by the concrete mix supplier Concrete mixes Containing Fly Ash: 14 days, or as approved by the pavement design engineer.

B. Curing and Protection (Curing Compound): 1. Apply curing compound to the entire area of the exposed surfaces of the concrete with a mechanical spray machine recommended by the compound manufacturer. Protect the spray fog from the wind with an adequate shield. Applied uniformly, at a minimum rate of 1 gallon to not more than 125 square feet. 2. Apply the compound with equipment of the pressure tank or pump type, equipped with a feed tank agitator, to insure continuous agitation of the compound during spraying operations. The nozzle shall be of the two-line type, with sufficient air to properly atomize the compound. 3. Do not apply the curing compound during or immediately after rainfall. If it becomes necessary to leave the pavement uncoated overnight, cover with polyethylene sheeting. Keep the sheeting in place until weather conditions are favorable for the application of the curing compound. 4. In the event that rain falls on the newly-coated pavement before the curing compound film has dried sufficiently to resist damage, or in the event that there is damage to the film from any cause whatsoever, apply a new coat of compound in one or two applications to the affected area. Apply at the rate that in the opinion of the Project Representative will result in a film of curing value equal to that specified for the original coat. 5. Distribute containers of curing compound on the work in a manner that will enable the Project Representative to determine the rate of application being used at any time. Withdraw curing compound for placement in the spray tanks directly from manufacturer's original containers, bearing the manufacturer's name, brand and lot number.

C01331C19 17 32 13 13 Portland Cement Concrete Paving 6. Apply the curing compound immediately after the concrete has been finished and after surplus water collected on the surface has disappeared. If hair checking develops in the pavement before finishing is completed, the Project Representative may order the application of the curing compound at an earlier stage. Remove from the pavement surface concrete cuts resulting from the finishing operations. If additional mortar is then needed to fill torn areas, place it ahead of the spraying operations. Immediately apply curing compound, at the rate specified above, to areas that are cut by finishing tools after the original application of curing compound. 7. If a curb section is to be placed separately, protect the surface of the pavement directly underneath the curb from the spraying of the curing compound. 8. Protect pavement edges that are exposed by the removal of the forms with an immediate application of curing compound. 9. Protect the compound, after application, from damage for the period of time specified above. Traffic, either by foot or otherwise, shall be considered damaging to the film of the applied compound. 10. Provide on the job a sufficient quantity of white or clear polyethylene sheeting to cover the pavement laid in 3 hours of maximum operation. Reserve this sheeting exclusively for the protection of the pavement in case of rain or breakdown of the spray equipment used for applying the curing compound. Place the protective sheeting over the pavement when ordered and in the manner directed by the Project Representative.

C. Curing and Protection (White Polyethylene Sheeting): 1. Place the sheeting over the pavement immediately after finishing operations are completed. 2. Lay the sheeting so that individual sheets overlap at least 2 feet, and the lapped areas are held in close contact with the pavement by weighting with earth or boards to prevent movement by the wind. Extend the sheeting downward to cover the edges of the pavement and secure it to the subgrade with a continuous bank of earth or surfacing material. Patch holes occurring in the sheeting immediately. The sheeting shall be protected from damage and remain in place for the minimum specified curing time.

D. Curing in Hot Weather: 1. In periods of low humidity, drying winds, or high temperatures, apply a fog spray to the concrete as soon after placement, and as conditions warrant in order to prevent the formation of shrinkage cracks. Continue the spray until conditions permit the application of a liquid curing membrane or other curing media. 2. The Project Representative will determine when weather conditions require the use of a fog spray.

E. Curing in Cold Weather: When the air temperature is expected to reach the freezing point during the day or night and the pavement has not cured for 50 percent of the time specified in Paragraph 3.12 A.3. of this Section, the concrete shall be protected from freezing. Provide a sufficient supply of straw, hay, grass, earth, blankets, or other suitable blanketing material, and spread it over the pavement to a sufficient depth to prevent freezing of the concrete. Remove and replace concrete that does not attain the strength or quality specified, or that is otherwise damaged by frost action or freezing.

C01331C19 18 32 13 13 Portland Cement Concrete Paving 3.13 FIELD SAMPLING AND TESTING

A. Field sampling and testing will be performed by the independent testing laboratory. Samples of aggregates and concrete will be taken at random locations and at such times as required to represent the quality of the materials and work throughout the project. The laboratory will provide the necessary labor, materials and facilities for sampling the aggregate and for casting, handling and storing the concrete samples at the site of work.

B. Furnish to the testing agency employed by King County the concrete required for casting specimens and for testing.

D. The testing agency will sample and test concrete as follows: 1. Perform strength tests making not less than 1 set of cylinders each day, not less than 1 set for each 75 cubic yards of concrete or for each 5,000 square feet of surface area placed. Depending upon the specified design age of concrete, each set of test specimens will be as follows: a. For 3-day concrete: 6 standard cylinders to test for compressive strength at 1, 3, and 7 days b. For 7-day concrete: 6 standard cylinders to test for compressive strength at 3, 7 and 14 days c. For 14-day concrete: 6 standard cylinders to test for compressive strength at 7, 14 and 28 days d. For 28-day concrete: 4 standard cylinders to test for the compressive strength of concrete Class C-5 at 14 and 28 days. e. For 1-day and 2-day concrete: 8 standard cylinders to test and compressive strength at 1, 2, 3, and 7 days 2. Perform slump tests immediately upon arrival of mix delivery trucks and periodically during placement. 3. Perform variability tests, air content tests and other tests specified or required with no less frequency than that of casting strength specimen sets. However, the Project Representative reserves the right of having the concrete tested as often as he deems necessary. 4. Sample according to ASTM C31, C42, and C172 and test according to the following: b. Compressive strength: ASTM C39 c. Air content: ASTM C231 d. Unit weight, yield air content, cement content and unit weight: ASTM C138 e. Slump: ASTM C143 f. Mixes with chemical additives: ASTM C494 and as required by Project Representative

E. It shall be expected that the concrete strength test results will correspond to the strength shown on the curves submitted for each concrete mix. If the test results deviate from the curves, and the Project Representative determines that said deviations are substantial so as to indicate that the minimum final design strengths will not be achieved, the Project Representative will exercise one of the options specified in Paragraph 1.05 G. of this Section.

C01331C19 19 32 13 13 Portland Cement Concrete Paving 3.14 REPAIR OF DEFECTIVE PAVEMENT PANELS

A. Prior to completion of joint sealing, if applicable as determined by the Project Representative, correct concrete work which does not conform to the specified requirements. Replace or, if the Project Representative determines that repairing is feasible, repair broken panels, random cracks, non working control joints near cracks, and spalling along joints and cracks. Perform replacement or repairing to the extent necessary to produce concrete work that meets the Specifications.

B. Remove and replace pavement panels containing multiple cracks through the full depth of the panel and separating the panel into three or more parts. When a single diagonal crack develops that intersects panel transverse and longitudinal joints at a distance from a corner equal to 1/3 of the width or length of the panel, remove and replace the smaller portion of the panel. Place the replacement portion with joints with load transferring dowels and following the normal joint pattern.

C. The Project Representative may determine that, due to location and characteristics, a random crack that penetrates the full depth of the pavement will not necessarily affect the pavement design performance. In such a case the Contractor will be allowed to repair the crack by working its entire length as required to produce a typical, sealed, control joint as detailed on the Drawings. To produce the joint, grove the top of the crack to the dimensions shown on the Drawings for the sealing of control joints by means of an approved grooving machine. The grooving machine shall be capable of following closely the path of the crack and of widening the top of the crack to the required section without spalling, or otherwise damaging the concrete. Remove fractured concrete and thoroughly clean the groove before sealing.

D. If the Project Representative determines that a random crack is tight, does not penetrate the full depth of the pavement, and will not affect pavement performance, leave the crack undisturbed. Inspect by core drilling if necessary to demonstrate that the crack penetration is not full depth.

E. Repair spalls by making a saw cut at least 1-inch outside the spalled area and to a minimum depth of 2 inches. When the spalled area abuts a joint, make the saw cut to a depth of 2 inches or 1/6 the panel thickness, whichever is greater. Chip the concrete between the saw cut and the joint or primary crack out until solid, undamaged concrete is exposed. Thoroughly clean the cavity thus formed of loose material. Apply a prime coat of epoxy-resin binder to the dry, cleaned surface of all sides of the cavity, except the joint or primary crack face; apply the prime coat by scrubbing coating material into the surface with a stiff bristle brush. Follow with placement of epoxy-resin concrete or mortar immediately after the application of the prime coat. If the spalled area to be patched abuts a working joint or a working crack which penetrates the full depth of a panel, use an insert, or other bond-breaking medium, to maintain the working properties of the joint during the repair work.

C01331C19 20 32 13 13 Portland Cement Concrete Paving 3.15 OPENING TO TRAFFIC

A. Unless otherwise approved in writing by the Project Representative, do not open newly constructed cement concrete pavement to traffic, including construction equipment, until the pavement has cured for the period of time specified in Paragraph 3.12 A.3. of this Section and attained a minimum compressive strength of 3,100 psi. The Project Representative may approve earlier opening of newly constructed pavement to traffic of construction equipment, or other vehicular traffic. However, approval will be limited to cases where neither subgrade of adjacent lanes to be paved nor adjacent shoulders nor unimproved areas are available for the operation of paving equipment. Approval will be conditioned upon the Contractor agreeing to the following restrictions: 1. Traffic will be restricted to vehicles with axle loads not exceeding 20,000 lbs. when the concrete in the newly paved lane has been tested and shown to have attained a compressive strength of no less than 2,500 psi, and has cured for at least the period of time specified in Paragraph 3.12 A.3. of this Section. 2. The surface of the new pavement is protected from scarring and abrasion by operating mixers, trucks and other construction equipment on mats, skids, or other protective devices. Sand, gravel, dirt, concrete or other debris deposited on the new pavement is removed daily. Replace damaged curing compound protection concurrently with the spraying of curing compound on the newly placed concrete. 3. Remove and replace, at no expense to King County, pavement panels that are cracked or broken as result of the Contractor's early opening of the lane to vehicle use.

B. Do not open for traffic pavement with curbs until the curb has cured for at least 72 hours or has attained 2,500 psi compressive strength. If the curb has not attained that strength, place standard barricades 1 foot away from the curb, and maintain them to the satisfaction of the Project Representative. Maintain such curb protection until the curb has cured and has attained the specified strength.

C. Prior to opening to traffic, clean the pavement to the satisfaction of the Project Representative.

2-09.3(1)E Backfilling

The backfilling of openings dug for Structures shall be a necessary part of and incidental to the excavation. Unless the Project Representative directs otherwise, backfill material shall be nonclay material containing no pieces more than 3 inches across, no frozen lumps, and no wood or other foreign material. When specified in the Contract or when approved by the Project Representative, the Contractor shall supply controlled density fill as backfill material. Controlled Density Fill (CDF) or Controlled Low-Strength Material (CLSM) – CDF is a self compacting, cementitious, flowable material requiring no subsequent vibration or tamping to achieve consolidation. The Contractor shall submit a mix design in conformance with Section 013300 of the Technical Specifications and utilize ACI 229 as a guide to develop the CDF mix design. No CDF shall be placed until the Project Representative has reviewed the mix design. CDF shall be designed to have a minimum 28-day strength of 50 psi and a maximum 28-day strength not to exceed 300 psi. The CDF consistency shall be flowable (approximate slump 3 to 10 inches). The following testing methods shall be used by the Contractor to develop the CDF mix design: 28-day compressive strength – ASTM D 4832; Unit weight, yield, and air content – ASTM D 6023; Slump – WSDOT FOP for AASHTO T 119. The water/cement ratio shall be calculated on the total weight of cementitious material. Cementitious materials are those listed in Section 5-05.2. Admixtures used in CDF shall meet the requirements of Section 9-23.6, Admixtures for Concrete, and foaming agents, if used, shall meet the requirements of ASTM C 869. Admixtures shall be used in accordance with the manufacturer’s recommendations and non-chloride accelerating admixtures may be used to accelerate the hardening of CDF. CDF shall meet the requirement of Section 310000, 2.01 G. of the Technical Specifications. Stockpiling – The Project Representative may require the Contractor to selectively remove and stockpile any usable material excavated for a Structure. If this material meets the requirements for gravel backfill for walls it may replace gravel as wall or abutment backfill. If the Contractor stockpiles excavated material for use as backfill, it shall be protected with plastic sheeting or by some other method from contamination and weather damage. If the material becomes too wet or contaminated in the stockpile, the Contractor shall dispose of and replace it with an equal amount of suitable material, all at no expense to the Contracting Agency. Compaction – Backfill from Structure excavation shall be placed and compacted in keeping with the following requirements: 1. Backfill supporting Roadbed, Roadway embankments, or Structures, including backfill providing lateral support for noise barrier wall foundations, luminaire poles, traffic signal standards, and roadside and overhead sign Structure foundations shall be placed in horizontal layers no more than 6 inches thick with each layer compacted to 95 percent of the maximum density determined by the Compaction Control Test according to Section 310000 of the Technical Specifications. 2. Gravel backfill for drains shall be placed in horizontal layers no more than 12 inches thick, with each layer compacted by at least three passes of a vibratory compactor approved by the Project Representative. 3. All other structure excavation backfill shall be placed in layers no more than 2 feet thick (loose), with each layer tamped and graded so that final settling will leave the backfill flush with surrounding ground. 4. Compaction of controlled density fill will not be required.

MARCH 2012 REV. Page 2-2 TSS

Timing – Backfill shall not be placed against any concrete structure until the concrete has attained 90 percent of its design strength and a minimum age of 14 days, except that reinforced concrete retaining walls 15 feet in height or less may be backfilled after the wall has attained 90 percent of its design compressive strength and curing requirements. Footings and columns may be backfilled as soon as forms have been removed, so long as the backfill is brought up evenly on all sides. The Project Representative may order the Contractor to use lean concrete in backfilling around piers and in front of abutments and walls. The Contracting Agency will pay for such backfilling as provided in Section 012900 of the Technical Specifications. If water prevents the Contractor from properly placing and compacting backfill, it shall be removed by pumping or other means.

Excavations shall be either closed up at the end of the day or protected to the satisfaction of the Project Representative. The trench width, depth and grade shall be as shown on the Drawings. Trenches must be of sufficient width in the pipe zone to permit proper installation and bedding of the pipe and to provide the required compaction of backfill. Above the top of the pipe zone, the Contractor may excavate to any width. All ledgerock, boulders, and stones shall be removed to provide a minimum of 6 inches clearance under all portions of the pipe. Placement of bedding material shall precede the installation of all pipe. This shall include necessary leveling of the native trench bottom or the top of the foundation material as well as placement and compaction of required bedding material to a uniform grade so that the entire length of pipe will be supported on a uniformly dense unyielding foundation. When, after excavating to the foundation level, the material remaining in the trench bottom is determined to be unsuitable by the Project Representative, excavation shall be continued to such additional depth and width as required by the Project Representative. Unsuitable foundation materials shall be disposed of at an approved site. The trench foundation shall be backfilled to the bottom of the pipe zone with gravel backfill for foundations, gravel backfill for pipe zone bedding, or other suitable material, and compacted to form a uniformly dense, unyielding foundation.

MARCH 2012 REV. Page 7-3 TSS

All material excavated from trenches and piled adjacent to the trench shall be maintained so that the toe of the slope is at least 2 feet from the edge of the trench. It shall be piled to cause a minimum of inconvenience to public travel, and provision shall be made for merging traffic where necessary. Free access shall be provided to all fire hydrants, water valves, and meters; and clearance shall be left to enable free flow of storm water in gutters, conduits, or natural watercourses. If the excavated material, or portions there from, meet the requirements of Section 9-03.12(3), the Project Representative may require that such material, in the quantity required, be selectively removed, stockpiled separately, and used as pipe bedding instead of quantities of gravel backfill for pipe zone bedding. If material so stockpiled becomes contaminated, the Contractor shall furnish suitable material in an amount equal to that lost by contamination at no expense to the King County. All costs involved in storing, protecting, re-handling, and placing the material shall be included in other items of work on the project. Excavation for manholes and other structures connected to the pipelines shall be sufficient to provide a minimum of 12 inches between their surfaces and the sides of the excavation. The Contractor shall furnish, install, and operate all necessary equipment to keep excavations above the foundation level free from water during construction, and shall dewater and dispose of the water so as not to cause injury to public or private property or nuisance to the public. Sufficient pumping equipment in good working condition shall be available at all times for all emergencies, including power outage, and shall have available at all times competent workers for the operation of the pumping equipment. Where pipe is to be placed in a new embankment, the embankment shall be constructed as shown in the Drawings or as directed by the Project Representative for a distance each side of the pipe location of not less than five times the diameter and to a minimum height equal to one-half of the outside diameter of the pipe. The embankment material shall be compacted to 95 percent density and the moisture content at the time of compaction shall be between optimum and 3 percentage points below optimum as determined by the Compaction Control Tests specified in Section 02300 “Earthwork” the Technical Specifications. The trench shall then be excavated to a width as specified in 02300 “Earthwork” of the Technical Specifications, and the pipe installed in accordance with the Contract Plan.

Upon completing the work, the Contractor shall remove all shoring unless the Drawings or the Project Representative direct otherwise. Shoring to be removed, or moveable trench shields or boxes, shall be located at least 2-1/2 pipe diameters away from metal or thermoplastic pipe if the bottom of the shoring, shield, or box extends below the top of the pipe, unless a satisfactory means of reconsolidating the bedding or side support material disturbed by shoring removal can be demonstrated. Damages resulting from improper shoring or failure to shore shall be the sole responsibility of the Contractor.

7-08.3(3) Backfilling

Delete in its entirety and replace with the following:

7-08.3(3) Backfilling

Placement of pipe zone backfill shall be performed in accordance with these requirements and the Contract Plan. Trenches shall be backfilled as soon after the pipe laying as possible. Pipe zone backfill material shall be clean earth or sand, free from clay, frozen lumps, roots, or moisture in excess of that permitting required compaction. Rocks or lumps larger than 3 inches maximum shall not be used for pipe zone backfill. Pipe zone backfill shall be placed in loose layers and compacted to 90 percent maximum density. Backfill shall be brought up simultaneously on each side of the pipe to the top of the pipe zone. The pipe shall then be covered to the top of the pipe zone and the materials compacted in a manner to avoid damaging or disturbing the completed pipe. Backfill above the pipe zone shall be accomplished in such a manner that the pipe will not be shifted out of position nor damaged by impact or overloading. If pipe is being placed in a new embankment, backfill above the pipe zone shall be placed in accordance with Section 02300 – “Earthwork”, or Section 02321 – “Trenching, Backfilling and Compacting” of the Technical Specifications. If pipe is being placed under existing paved areas, or roadways, backfill above the pipe zone shall be placed in horizontal layers no more than 6 inches thick and compacted to 95 percent maximum density. If pipe is being placed in non-traffic areas, backfill above the pipe zone shall be placed in horizontal layers no more than 6 inches thick and shall be compacted to 85 percent maximum density. All compaction shall be in accordance with the Compaction Control Test of Section 02300 – “Earthwork”, or Section 02321 – “Trenching, Backfilling and Compacting” of the Technical Specifications. Material excavated from the trench shall be used for backfill above the pipe zone, except that organic material, frozen lumps, wood, rocks, or pavement chunks larger than 6 inches in maximum dimension shall not be used.

MARCH 2012 REV. Page 7-4 TSS

Materials determined by the Project Representative to be unsuitable for backfill at the time of excavation shall be removed and replaced with imported backfill material. Backfilling of trenches in the vicinity of catch basins, manholes, or other appurtenances will not be permitted until the cement in the masonry has become thoroughly hardened. When it is required that a blanket of select material or bank run gravel is to be placed on top of the native backfill, the backfill shall be placed to the elevations shown in the Drawings, or to the elevations specified by the Project Representative. Compaction of the native material shall be as required by the King County and shall be performed prior to placing the select material. Surface material shall be loosened to whatever depth is required to prevent bridging of the top layer, but shall in no case be less than 18 inches. The Contractor shall not operate tractors or other heavy equipment over the top of the pipe until the backfill has reached a height of 2 feet above the top of the pipe.
