Provision either supplements, modifies, or replaces the comparable Standard Specification, or is
a new Provision. The deletion, amendment, alteration, or addition to any subsection or portion
of the Standard Specifications is meant to pertain only to that particular portion of the section,
and in no way should it be interpreted that the balance of the section does not apply.
The project-specific Special Provisions are not labeled as such. The GSPs are labeled under
the headers of each GSP, with the effective date of the GSP and its source. For example:
(March 8, 2013 APWA GSP)

Agency Work or for Work done for others, as judged from the standpoint of conduct
of the Work; workmanship; progress; affirmative action; equal employment

l. There are any other reasons deemed proper by the Contracting Agency.
The Contracting Agency will verify that the Bidder meets the mandatory bidder responsibility
criteria in RCW 39.04.350(1l). To assess Bidder responsibility, the Contracting Agency
reserves the right to request further documentation as needed from the low Bidder and
documentation from other Bidders as well to assess Bidder responsibility and compliance
with all Bidder responsibility criteria. The Contracting Agency also reserves the right to
obtain information from third-parties and independent sources of information concerning a
Bidder’s compliance with the mandatory and supplemental criteria, and to use that
information in their evaluation. The Contracting Agency may consider mitigating factors in
determining whether the Bidder complies with the requirements of the Supplemental
Criteria.

criteria above and is therefore not a responsible Bidder, the Contracting Agency shall notify
the Bidder in writing, with the reasons for its determination. If the Bidder disagrees with this
determination, it may appeal the determination within two (2) business days of the
Contracting Agency’s determination by presenting its appeal and any additional information
to the Contracting Agency. The Contracting Agency will consider the appeal and any
additional information before issuing its final determination. If the final determination affirms

any other Bidder until at least two (2) business days after the Bidder determined to be not
responsible has received the Contracting Agency’s final determination.

1-03 AWARD AND EXECUTION OF CONTRACT
1-03.1 Consideration of Bids
(June 02, 2023 Renton GSP)
Revise the first paragraph to read:
After opening and reading proposals, the Contracting Agency will check them for
correctness of extensions of the prices per unit and the total price. If a discrepancy exists
between the price per unit and the extended amount of any bid item, the price per unit will
control. If a minimum bid amount has been established for any item and the bidder’s unit or
lump sum price is less than the minimum specified amount, the Contracting Agency will
unilaterally revise the unit or lump sum price, to the minimum specified amount and
Monroe Ave Infiltration Facility SP-12 Special Provisions
City of Renton
recalculate the extension. The total of extensions, corrected where necessary, including
sales taxes where applicable and such additives and/or alternates as selected by the
Contracting Agency, will be used by the Contracting Agency for award purposes and to fix
the Awarded Contract Price amount and the amount of the contract bond.
Revise the first sentence of the third paragraph to read:
A Bidder who wishes to claim error after the Bids have been publicly opened and read as
required by section1-02.12, shall promptly notify the Contracting Agency that an error has
occurred.
Revise the last sentence of the fourth paragraph to read:
If the Contracting Agency does not concur in the error or determines that the error is not the
kind for which the law allows relieve, the Contracting Agency may Award the Contract and if
the Bidder refuses to execute the Contract, the Bidder’s Bid deposit shall be forfeited as
required by RCW 35.23.352. Per RCW 39.04.107, a low bidder on a public works project
who claims error and fails to enter into a contract is prohibited from bidding on the same
project if a second or subsequent call for bids is made for the project.
Supplement this section as follows:
All bids will be based on total sum of all schedules of prices. No partial bids will be accepted
unless so stated in the call for bids or special provisions. The City reserves the right to

Supplement this section with the following:
If the Contractor fails to remedy defective or unauthorized work within the time specified in a
written notice from the Engineer, or fails to perform any part of the work required by the
Contract Documents, the Engineer may correct and remedy such work as may be identified

Contracting Agency may deem necessary.
If the Contractor fails to comply with a written order to remedy what the Engineer determines
to be an emergency situation, the Engineer may have the defective and unauthorized work
Monroe Ave Infiltration Facility SP-19 Special Provisions
City of Renton
corrected immediately, have the rejected work removed and replaced, or have work the
Contractor refuses to perform completed by using Contracting Agency or other forces. An
emergency situation is any situation when, in the opinion of the Engineer, a delay in its
remedy could be potentially unsafe, or might cause serious risk of loss or damage to the
public.
Direct or indirect costs incurred by the Contracting Agency 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 will be deducted by the Engineer from

and costs for repair and replacement of work of others destroyed or damaged by correction,
removal, or replacement of the Contractor’s unauthorized work.
No adjustment in contract time or compensation will be allowed because of the delay in the
performance of the work attributable to the exercise of the Contracting Agency’s rights

the Contractor’s failure to perform the work as required.
1-05.10 Removal of Defective and Unauthorized Work
(June 2023 Renton GSP)

remove it from the project site and replace it with non-defective and authorized Work, all
without cost to the Contracting Agency. If the Contractor does not promptly comply with the
written order to correct defective and/or unauthorized Work, or if an emergency exists, the
Contracting Agency reserves the right to have defective and/or unauthorized Work corrected
or removed and replaced pursuant to Section 1-05.7 “Removal of Defective and/or
Unauthorized Work.”

in writing, or liability expressed of implied arising out of a written agreement.
The Contractor shall warrant good title to all materials, supplies, and equipment purchased

or impair the right of persons furnishing materials or labor, to recover under any bond given
by the Contractor for their protection, or any rights under any law permitting such persons to
look to funds due the Contractor in the hands of the Contracting Agency.
Monroe Ave Infiltration Facility SP-20 Special Provisions
City of Renton

1-05.11 Final Inspection
Delete this section and replace it with the following:
1-05.11 Final Inspections and Operational Testing
(October 1, 2005 APWA GSP)
1-05.11(1) Substantial Completion Date
When the Contractor considers the work to be substantially complete, the Contractor shall
so notify the Engineer and request the Engineer establish the Substantial Completion Date.
The Contractor’s request shall list the specific items of work that remain to be completed in
order to reach physical completion. The Engineer will schedule an inspection of the work
with the Contractor to determine the status of completion. The Engineer may also establish
the Substantial Completion Date unilaterally.
To be considered substantially complete the following conditions must be met:
1. The Contracting Agency must have full and unrestricted use and benefit of the
facilities both from the operational and safety standpoint.
2. Only minor incidental Work, replacement of temporary substitute facilities, or
correction of repair Work remains to reach physical completion of the Work.
If, after this inspection, the Engineer concurs with the Contractor that the work is
substantially complete and ready for its intended use, the Engineer, by written notice to the
Contractor, will set the Substantial Completion Date. If, after this inspection the Engineer
does not consider the work substantially complete and ready for its intended use, the
Engineer will, by written notice, so notify the Contractor giving the reasons therefor.
Upon receipt of written notice concurring in or denying substantial completion, whichever is
applicable, the Contractor shall pursue vigorously, diligently and without unauthorized
interruption, the work necessary to reach Substantial and Physical Completion. The
Contractor shall provide the Engineer with a revised schedule indicating when the
Contractor expects to reach substantial and physical completion of the work.
The above process shall be repeated until the Engineer establishes the Substantial
Completion Date and the Contractor considers the work physically complete and ready for
final inspection.
1-05.11(2) Final Inspection and Physical Completion Date
When the Contractor considers the work physically complete and ready for final inspection,
the Contractor by written notice, shall request the Engineer to schedule a final inspection.
The Engineer will set a date for final inspection. The Engineer and the Contractor will then
make a final inspection and the Engineer will notify the Contractor in writing of all particulars
in which the final inspection reveals the work incomplete or unacceptable. The Contractor
shall immediately take such corrective measures as are necessary to remedy the listed
deficiencies. Corrective work shall be pursued vigorously, diligently, and without interruption
until physical completion of the listed deficiencies. This process will continue until the
Engineer is satisfied the listed deficiencies have been corrected.
Monroe Ave Infiltration Facility SP-21 Special Provisions
City of Renton
If action to correct the listed deficiencies is not initiated within 7 days after receipt of the
written notice listing the deficiencies, the Engineer may, upon written notice to the
Contractor, take whatever steps are necessary to correct those deficiencies pursuant to
Section 1-05.7.
The Contractor will not be allowed an extension of contract time because of a delay in the
performance of the work attributable to the exercise of the Engineer’s right hereunder.
Upon correction of all deficiencies, the Engineer will notify the Contractor and the
Contracting Agency, in writing, of the date upon which the work was considered physically
complete. That date shall constitute the Physical Completion Date of the contract, but shall
not imply acceptance of the work or that all the obligations of the Contractor under the
contract have been fulfilled.
1-05.11(3) Operational Testing
Unless otherwise noted in the Contract Documents, the Contractor shall give the Engineer a
minimum of 3 working days notice of the time for each test and inspection. If the inspection
is by another authority than the Engineer, the Contractor shall give the Engineer a minimum
of 3 working days notice of the date fixed for such inspection. Required certificates of
inspection by other authority than the Engineer shall be secured by the Contractor.
It is the intent of the Contracting Agency 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 or signal
systems; irrigation systems; buildings; or other similar work it may be desirable for the
Engineer to have the 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. During and following the test period, the Contractor shall correct any items
of workmanship, materials, or equipment which 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 unit contract prices
related to the system being tested, unless specifically set forth otherwise in the proposal.
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.

The bid items listed in Section 1-09.14 will be the only items for which compensation will be
made for the Work described in each section of the Standard Specifications when the
Contractor performs the specified Work. Should a bid item be listed in a “Payment” clause
but not in the Proposal Form, and Work for that item is performed by the Contractor and the
Work is not stated as included in or incidental to a pay item in the Contract and is not Work
that would be required to complete the intent of the Contract per Section 1-04.1, then
payment for that Work will be made as for Extra Work pursuant to a Change Order.
The words “Bid Item,” “Contract Item,” and “Pay Item,” and similar terms used throughout
the Contract Documents are synonymous.
If the “payment” clause in the Specifications relating to any unit bid item price in the
Proposal Form requires that said unit bid item price cover and be considered compensation
for certain Work or material essential to the item, then the Work or material will not be
measured or paid for under any other unit bid item which may appear elsewhere in the
Proposal Form or Specifications.
Pluralized unit bid items appearing in these Specifications are changed to singular form.
Payment for bid items listed or referenced in the “Payment” clause of any particular section
of the Specifications shall be considered as including all of the Work required, specified, or
described in that particular section. Payment items will generally be listed generically in the
Specifications, and specifically in the bid form. When items are to be “furnished” under one
payment item and “installed” under another payment item, such items shall be furnished
FOB project site, or, if specified in the Special Provisions, delivered to a designated site.
Materials to be “furnished,” or “furnished and installed” under these conditions, shall be the
responsibility of the Contractor with regard to storage until such items are incorporated into
the Work or, if such items are not to be incorporated into the Work, delivered to the
applicable Contracting Agency storage site when provided for in the Specifications. Payment
for material “furnished,” but not yet incorporated into the Work, may be made on monthly
estimates to the extent allowed.
1-09.6 Force Account
(October 10, 2008 APWA GSP)
Supplement this section with the following:
The Contracting Agency has estimated and included in the Proposal, dollar amounts for all
items to be paid per force account, only to provide a common proposal for Bidders. All such
dollar amounts are to become a part of Contractor's total bid. However, the Contracting
Agency does not warrant expressly or by implication, that the actual amount of work will
correspond with those estimates. Payment will be made on the basis of the amount of work
actually authorized by Engineer.
Monroe Ave Infiltration Facility SP-50 Special Provisions
City of Renton
1-09.7 Mobilization
(June 2023 Renton GSP)

at end of project for Final Cleanup, the movement of Contractor's personnel, equipment,
supplies, and incidentals to and from the project site; the establishment of an office,
buildings, and other facilities necessary for Work on the project; providing sanitary facilities
for the Contractor's personnel; and obtaining permits or licenses required to complete the
project not furnished by the Owner.
Mobilization shall also include all activities required to demobilize from site and provide Final
Cleanup, per Special Provisions Section 1-04.11, including a final site walk with City.
Payment will be made for the following bid item(s):
“Mobilization,” Lump Sum.
1-09.9 Payments
(March 13, 2012 APWA GSP)
Supplement this section with the following:
Lump sum item breakdowns are not required when the bid price for the lump sum item is
less than $20,000.
(January 19, 2022 APWA GSP)
Section 1-09.9 is revised to read:
The basis of payment will be the actual quantities of Work performed according to the
Contract and as specified for payment.
The Contractor shall submit a breakdown of the cost of lump sum bid items at the
Preconstruction Conference, to enable the Project Engineer to determine the Work
performed on a monthly basis. A breakdown is not required for lump sum items that include
a basis for incremental payments as part of the respective Specification. Absent a lump
sum breakdown, the Project Engineer will make a determination based on information
available. The Project Engineer’s determination of the cost of work shall be final.
Progress payments for completed work and material on hand will be based upon progress
estimates prepared by the Engineer. A progress estimate cutoff date will be established at
the preconstruction conference.
The initial progress estimate will be made not later than 30 days after the Contractor
commences the work, and successive progress estimates will be made every month
thereafter until the Completion Date. Progress estimates made during progress of the work
are tentative, and made only for the purpose of determining progress payments. The
progress estimates are subject to change at any time prior to the calculation of the final
payment.
The value of the progress estimate will be the sum of the following:
Monroe Ave Infiltration Facility SP-51 Special Provisions
City of Renton
1. Unit Price Items in the Bid Form — the approximate quantity of acceptable units of
work completed multiplied by the unit price.
2. Lump Sum Items in the Bid Form — based on the approved Contractor’s lump sum
breakdown for that item, or absent such a breakdown, based on the Engineer’s
determination.
3. Materials on Hand — 100 percent of invoiced cost of material delivered to Job site or
other storage area approved by the Engineer.
4. Change Orders — entitlement for approved extra cost or completed extra work as
determined by the Engineer.
Progress payments will be made in accordance with the progress estimate less:
1. Retainage per Section 1-09.9(1), on non FHWA-funded projects;
2. The amount of progress payments previously made; and
3. Funds withheld by the Contracting Agency for disbursement in accordance with the
Contract Documents.
Progress payments for work performed shall not be evidence of acceptable performance or
an admission by the Contracting Agency that any work has been satisfactorily completed.
The determination of payments under the contract will be final in accordance with Section 1
05.1.
Failure to perform any of the obligations under the Contract by the Contractor may be
decreed by the Contracting Agency to be adequate reason for withholding any payments
until compliance is achieved.
Upon completion of all Work and after final inspection (Section 1-05.11), the amount due the
Contractor under the Contract will be paid based upon the final estimate made by the
Engineer and presentation of a Final Contract Voucher Certification to be signed by the
Contractor. The Contractor's signature on such voucher shall be deemed a release of all
claims of the Contractor unless a Certified Claim is filed in accordance with the requirements
of Section 1-09.11 and is expressly excepted from the Contractor’s certification on the Final
Contract Voucher Certification. The date the Contracting Agency signs the Final Contract
Voucher Certification constitutes the final acceptance date (Section 1-05.12).
If the Contractor fails, refuses, or is unable to sign and return the Final Contract Voucher
Certification or any other documentation required for completion and final acceptance of the
Contract, the Contracting Agency reserves the right to establish a Completion Date (for the
purpose of meeting the requirements of RCW 60.28) and unilaterally accept the Contract.
Unilateral final acceptance will occur only after the Contractor has been provided the
opportunity, by written request from the Engineer, to voluntarily submit such documents. If
voluntary compliance is not achieved, formal notification of the impending establishment of a
Completion Date and unilateral final acceptance will be provided by email with delivery
confirmation from the Contracting Agency to the Contractor, which will provide 30 calendar
days for the Contractor to submit the necessary documents. The 30 calendar day period will
begin on the date the email with delivery confirmation is received by the Contractor. The
date the Contracting Agency unilaterally signs the Final Contract Voucher Certification shall
constitute the Completion Date and the final acceptance date (Section 1-05.12). The
reservation by the Contracting Agency to unilaterally accept the Contract will apply to
Contracts that are Physically Completed in accordance with Section 1-08.5, or for Contracts
that are terminated in accordance with Section 1-08.10. Unilateral final acceptance of the
Monroe Ave Infiltration Facility SP-52 Special Provisions
City of Renton
Contract by the Contracting Agency does not in any way relieve the Contractor of their
responsibility to comply with all Federal, State, tribal, or local laws, ordinances, and
regulations that affect the Work under the Contract.
Payment to the Contractor of partial estimates, final estimates, and retained percentages
shall be subject to controlling laws.
1-09.9(1) Retainage
(June 2023, Renton GSP)
Supplement this section with the following:
The retained amount shall be released as stated in the Standard Specifications if no claims
have been filed against such funds as provided by law, and if the Owner has no unsatisfied
claims against the Contractor. In the event claims are filed, the Owner shall withhold, until
such claims are satisfied, a sum sufficient to satisfy all claims and to pay attorney's fees. In
addition, the Owner shall withhold such amount as is required to satisfy any claims by the
Owner against the Contractor, until such claims have been finally settled.
Neither the final payment nor any part of the retained percentage shall become due until the
Contractor, if requested, delivers to the Owner a complete release of all liens arising out of
this Contract, or receipts in full in lieu thereof, and, if required in either case, an affidavit that
so far as the Contractor has knowledge or information, the release and receipts include all
labor and materials for which a lien could be filed: but the Contractor may, if any
subcontractor refuses to furnish a release or receipt in full, furnish a bond satisfactorily to
the Engineer to indemnify the Owner against the lien. If any lien remains unsatisfied after all
payments are made, the Contractor shall reimburse to the Owner all monies that the latter
may be compelled to pay in discharging such lien, including all costs and reasonable
engineer's and attorney's fees.
Add the following new section:
1-09.9(2) Contracting Agency’s Right to Withhold and Disburse Certain Amounts
(June 2023, Renton GSP)
In addition to monies retained pursuant to RCW 60.28 and subject to RCW 39.04.250, RCW
39.12 and RCW 39.76, the Contractor authorizes the Engineer to withhold progress
payments due or deduct an amount from any payment or payments due the Contractor
which, in the Engineer’s opinion, may be necessary to cover the Contracting Agency’s costs
for or to remedy the following situations:
1. Damage to another contractor when there is evidence thereof and a claim has been
filed.
2. Where the Contractor has not paid fees or charges to public authorities of
municipalities, which the Contractor is obligated to pay.
3. Utilizing material tested and inspected by the Engineer, for purposes not connected
with the Work (Section 1-05.6).
4. Landscape damage assessments per Section 1-07.16.
5. For overtime Work performed by City personnel per Section 1-08.1(4).
6. Anticipated or actual failure of the Contractor to complete the Work on time:
a. Per Section 1-08.9 Liquidated Damages; or
b. Lack of construction progress based upon the Engineer’s review of the
Contractor’s approved progress schedule, which indicates the Work will not
be complete within the contract time. When calculating an anticipated time
overrun, the Engineer will make allowances for weather delays, approved
Monroe Ave Infiltration Facility SP-53 Special Provisions
City of Renton
unavoidable delays, and suspensions of the Work. The amount withheld
under this subparagraph will be based upon the liquidated damages amount
per day set forth in Contract Documents multiplied by the number of days the
Contractor’s approved progress schedule, in the opinion of the Engineer,
indicates the Contract may exceed the Contract Time.
7. Failure of the Contractor to perform any of the Contractor’s other obligations under
the Contract, including but not limited to:
a. Failure of the Contractor to provide the Engineer with a field office when
required by the Contract Provisions.
b. Failure of the Contractor to protect survey stakes, markers, etc., or to provide
adequate survey Work as required by Section 1-05.5.
c. Failure of the Contractor to correct defective or unauthorized Work (Section
1-05.8).
d. Failure of the Contractor to furnish a Manufacture’s Certificate of Compliance
in lieu of material testing and inspection as required by Section 1-06.3.
e. Failure to submit weekly payrolls, Intent to Pay Prevailing Wage forms, or
correct underpayment to employees of the Contractor or subcontractor of any
tier as required by Section 1-07.9.
f. Failure of the Contractor to pay worker’s benefits (Title 50 and Title 51 RCW)
as required by Section 1-07.10.
g. Failure of the Contractor to submit and obtain approval of a progress
schedule per Section 1-08.3.
The Contractor authorizes the Engineer to act as agent for the Contractor disbursing such
funds as have been withheld pursuant to this Section to a party or parties who are entitled to
payment. Disbursement of such funds, if the Engineer elects to do so will be made only
after giving the Contractor 15 calendar days prior written notice of the Contracting Agency’s
intent to do so, and if prior to the expiration of the 15-calendar day period,
1. No legal action has commenced to resolve the validity of the claims, and
2. The Contractor has not protested such disbursement.
A proper accounting of all funds disbursed on behalf of the Contractor in accordance with
this Section will be made. A payment made pursuant to this section shall be considered as
payment made under the terms and conditions of the Contract. The Contracting Agency
shall not be liable to the Contractor for such payment made in good faith.
Add the following new section:
1-09.9(3) Final Payment
(June 2023, Renton GSP)
Upon Acceptance of the Work by the Contracting Agency, the final amount to be paid the
Contactor will be calculated based upon a Final Progress Estimate made by the Engineer.
Acceptance by the Contractor of the final payment shall be and shall operate as a release:
1. To the Contracting Agency of all claims and all liabilities of the Contractor, other than
claims in stated amounts as may be specifically excepted in writing by the
Contractor;
2. For all things done or furnished in connection with the Work;
3. For every act and neglect by the Contracting Agency; and
4. For all other claims and liability relating to or arising out of the Work.
A payment (monthly, final, retainage, or otherwise) shall not release the Contractor or the
Contractor’s Surety from any obligation required under the terms of the Contract Documents
or the Contract Bond; nor shall such payment constitute a waiver of the Contracting
Agency’s ability to investigate and act upon findings of non-compliance with the WMBE
Monroe Ave Infiltration Facility SP-54 Special Provisions
City of Renton
requirements of the Contract; nor shall such payment preclude the Contracting Agency from
recovering damages, setting penalties, or obtaining such other remedies as may be
permitted by law.
Before the Work will be accepted by the Contracting Agency, the Contractor shall submit an
affidavit, on the form provided by the Engineer, of amounts paid to certified disadvantaged
(DB), minority (MBE) or women business enterprises (WBE) participating in the Work. Such
affidavit shall certify the amounts paid to the DB, MBE or WBE subcontractors regardless of
tier.
On federally funded projects the Contractor may also be required to execute and furnish the
Contracting Agency an affidavit certifying that the Contractor has not extended any loans,
gratuity or gift and money pursuant to Section 1-07.19 of these Specifications.
If the Contractor fails, refuses, or is unable to sign and return the Final Progress Estimate or
any other documents required for the final acceptance of the Contract, the Contracting
Agency reserves the right to establish a completion date and unilaterally accept the
Contract. Unilateral acceptance will occur only after the Contractor has been provided the
opportunity, by written request from the Engineer, to voluntarily submit such documents. If
voluntary compliance is not achieved, formal notification of the impending unilateral
acceptance will be provided by certified letter from the Engineer to the Contractor that will
provide 30 calendar days for the Contractor to submit the necessary documents. The 30-
calendar day deadline shall begin on the date of the postmark of the certified letter
from the Engineer requesting the necessary documents. This reservation by the
Contracting Agency to unilaterally accept the Contract will apply to contracts that are
completed in accordance with Section 1-08.5 for contracts that are terminated in accordance
with Section 1-08.10. Unilateral acceptance of the Contract by the Contracting Agency does
not in any way relieve the Contractor of the provisions under contract or of the responsibility
to comply with all laws, ordinances, and federal, state, and local regulations that affect the
Contract. The date the Contracting Agency unilaterally signs the Final Progress Estimate
constitutes the final acceptance date (Section 1-05.12).

(June 2023, Renton GSP)
Revise paragraph 5 to read:
Failure to submit with the Final Application for Payment such information and details as

agreed that any such claims or causes of action shall be brought only in the Superior Court
of the county where the Contracting Agency headquarters is located, provided that where

Contractor asserts against the Contracting Agency arising from the Contract are filed with
the Contracting Agency or initiated in court, the Contractor shall permit the Contracting

provided that where claims subject to arbitration are asserted against a county, RCW
36.01.050 shall control venue and jurisdiction of the Superior Court. The decision of the
arbitrator and the specific basis for the decision shall be in writing. The arbitrator shall use
the Contract as a basis for decisions.

3. Is arbitrary and/or is not based upon the applicable facts and the law controlling the
issues submitted to arbitration. The board of arbitrators shall support its decision by

at any such hearing.
The arbitration shall be conducted in accordance with the statutes of the State of
Washington and court decisions governing such procedure.
The costs of such arbitration shall be borne equally by the City and the Contractor unless it
is the board's majority opinion that the Contractor's filing of the protest or action is capricious
or without reasonable foundation. In the latter case, all costs shall be borne by the
Contractor.
1-09.13(4) Venue for Litigation
(January 19, 2022 APWA GSP)
Revise this section to read:

shall be placed on both outer edges of the Traveled Way of each Roadway. Horizontal
control utilizing the reference line will be permitted. The grade and slope for intermediate
lanes shall be controlled automatically from reference lines or by means of a mat
referencing device and a slope control device. When the finish of the grade prepared for
paving is superior to the established tolerances and when, in the opinion of the Engineer,
Monroe Ave Infiltration Facility SP-97 Special Provisions
City of Renton
further improvement to the line, grade, cross-section, and smoothness can best be achieved
without the use of the reference line, a mat referencing device may be substituted for the
reference line. Substitution of the device will be subject to the continued approval of the
Engineer. A joint matcher may be used subject to the approval of the Engineer. The
reference line may be removed after the completion of the first course of HMA when
approved by the Engineer. Whenever the Engineer determines that any of these methods
are failing to provide the necessary vertical control, the reference lines will be reinstalled by
the Contractor.
The Contractor shall furnish and install all pins, brackets, tensioning devices, wire, and
accessories necessary for satisfactory operation of the automatic control equipment.
If the paving machine in use is not providing the required finish, the Engineer may suspend
Work as allowed by Section 1-08.6. Any cleaning or solvent type liquids spilled on the
pavement shall be thoroughly removed before paving proceeds.
5-04.3(3)D Material Transfer Device or Material Transfer Vehicle
A Material Transfer Device/Vehicle (MTD/V) shall only be used with the Engineer’s approval,
unless otherwise required by the Contract.
Where an MTD/V is required by the Contract, the Engineer may approve paving without an
MTD/V, at the request of the Contractor. The Engineer will determine if an equitable
adjustment in cost or time is due.
When used, the MTD/V shall mix the HMA after delivery by the hauling equipment and prior
to laydown by the paving machine. Mixing of the HMA shall be sufficient to obtain a uniform
temperature throughout the mixture. If a windrow elevator is used, the length of the windrow
may be limited in urban areas or through intersections, at the discretion of the Engineer.
To be approved for use, an MTV:
1. Shall be self-propelled vehicle, separate from the hauling vehicle or paver.
2. Shall not be connected to the hauling vehicle or paver.

aggregate will not be permitted. Rollers producing pickup, washboard, uneven compaction
of the surface, displacement of the mixture or other undesirable results shall not be used.
5-04.3(4) Preparation of Existing Paved Surfaces
When the surface of the existing pavement or old base is irregular, the Contractor shall bring
it to a uniform grade and cross-section as shown on the Plans or approved by the Engineer.
Preleveling of uneven or broken surfaces over which HMA is to be placed may be
accomplished by using an asphalt paver, a motor patrol grader, or by hand raking, as
approved by the Engineer.
Compaction of preleveling HMA shall be to the satisfaction of the Engineer and may require
the use of small steel wheel rollers, plate compactors, or pneumatic rollers to avoid bridging
across preleveled areas by the compaction equipment. Equipment used for the compaction
of preleveling HMA shall be approved by the Engineer.
Before construction of HMA on an existing paved surface, the entire surface of the

application of tack coat, or paving, the condition of the surface shall be approved by the
Engineer.
A tack coat of asphalt shall be applied to all paved surfaces on which any course of HMA is
to be placed or abutted; except that tack coat may be omitted from clean, newly paved
surfaces at the discretion of the Engineer. Tack coat shall be uniformly applied to cover the
existing pavement with a thin film of residual asphalt free of streaks and bare spots at a rate
between 0.02 and 0.10 gallons per square yard of retained asphalt. The rate of application
shall be approved by the Engineer. A heavy application of tack coat shall be applied to all
joints. For Roadways open to traffic, the application of tack coat shall be limited to surfaces
that will be paved during the same working shift. The spreading equipment shall be
equipped with a thermometer to indicate the temperature of the tack coat material.
Equipment shall not operate on tacked surfaces until the tack has broken and cured. If the
Contractor’s operation damages the tack coat it shall be repaired prior to placement of the
HMA.
The tack coat shall be CSS-1, or CSS-1h emulsified asphalt. The CSS-1 and CSS-1h
emulsified asphalt may be diluted once with water at a rate not to exceed one-part water to
one-part emulsified asphalt. The tack coat shall have sufficient temperature such that it may
be applied uniformly at the specified rate of application and shall not exceed the maximum
temperature recommended by the emulsified asphalt manufacturer.

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.
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 AASH-TO 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

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
Monroe Ave Infiltration Facility SP-104 Special Provisions
City of Renton
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 Specifications, its individual pay
factor will be considered 1.00 in calculating the CPF.
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 Specifications, its individual pay
factor will be considered 1.00 in calculating the CPF.
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 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 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.
Monroe Ave Infiltration Facility SP-105 Special Provisions
City of Renton
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 will 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.
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.

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)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.
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

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 of HMA in the compaction control lot in tons, and the unit Contract price per ton of
mix.
