work of structural steel installation, rebar installation, heating, ventilation and air conditioning, plumbing, as described in
Chapter 18.106 RCW, and electrical, as described in Chapter 19.28 RCW or naming more than one subcontractor to perform
the same work will result in your bid being non-responsive and therefore void.
Subcontractor(s) with whom the bidder will directly subcontract that are proposed to perform the work of structural steel installation,
rebar installation, heating, ventilation and air conditioning, plumbing, as described in Chapter 18.106 RCW, and electrical as
described in Chapter 19.28 RCW must be listed below. The work to be performed is to be listed below the subcontractor(s) name.

Proposal for Incorporating Recycled Materials into the Project
In compliance with RCW 70A.205.700, the Bidder shall propose below, the total percent of
construction aggregate and concrete materials to be incorporated into the Project that are
recycled materials. Calculated percentages must be within the amounts allowed in Section
9-03.21(1)E, Table on Maximum Allowable Percent (By Weight) of Recycled Material, of the
Standard Specifications.
Proposed total percentage: _____________________________ percent.
Note: Use of recycled materials is highly encouraged within the limits shown above, but does
not constitute a Bidder Preference, and will not affect the determination of award, unless two or
more lowest responsive Bid totals are exactly equal, in which case proposed recycling
percentages will be used as a tie-breaker, per the APWA GSP in Section 1-03.1 of the Special
Provisions. Regardless, the Bidder’s stated proposed percentages will become a goal the
Contractor should do its best to accomplish. Bidders will be required to report on recycled

additional information before issuing its final determination. If the final
14
determination affirms that the Bidder is not responsible, the Contracting Agency
will not execute a contract with any other Bidder until at least two business days
after the Bidder determined to be not responsible has received the Contracting
Agency’s final determination.
Request to Change Supplemental Bidder Responsibility Criteria Prior To Bid:

1-03.1 Consideration of Bids
(December 30, 2022 APWA 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 recalculate the extension. The total of
15
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.
1-03.1(1) Identical Bid Totals
(December 30, 2022 APWA GSP)
Revise this section to read:
After opening Bids, if two or more lowest responsive Bid totals are exactly equal, then the tie-
breaker will be the Bidder with an equal lowest bid, that proposed to use the highest percentage
of recycled materials in the Project, per the form submitted with the Bid Proposal. If those
percentages are also exactly equal, then the tie-breaker will be determined by drawing as
follows: Two or more slips of paper will be marked as follows: one marked “Winner” and the
other(s) marked “unsuccessful”. The slips will be folded to make the marking unseen. The slips
will be placed inside a box. One authorized representative of each Bidder shall draw a slip from
the box. Bidders shall draw in alphabetic order by the name of the firm as registered with the
Washington State Department of Licensing. The slips shall be unfolded and the firm with the
slip marked “Winner” will be determined to be the successful Bidder and eligible for Award of
the Contract. Only those Bidders who submitted a Bid total that is exactly equal to the lowest
responsive Bid, and with a proposed recycled materials percentage that is exactly equal to the
highest proposed recycled materials amount, are eligible to draw.
1-03.3 Execution of Contract
(July 8, 2024 APWA GSP Option A)
Revise this section to read:
Within 3 calendar days of Award date (not including Saturdays, Sundays and Holidays), the

shall provide any pre-award information the Contracting Agency may require under Section 1-
02.15.
16
Until the Contracting Agency executes a contract, no proposal shall bind the Contracting
Agency nor shall any work begin within the project limits or within Contracting Agency-
furnished sites. The Contractor shall bear all risks for any work begun outside such areas and
for any materials ordered before the contract is executed by the Contracting Agency.
If the bidder experiences circumstances beyond their control that prevents return of the
contract documents within the calendar days after the award date stated above, the
Contracting Agency may grant up to a maximum of 10 additional calendar days for return of the
documents, provided the Contracting Agency deems the circumstances warrant it.
1-03.4 Contract Bond
(July 23, 2015 APWA GSP)
Delete the first paragraph and replace it with the following:

1-05 CONTROL OF THE WORK
18
1-05.7 Removal of Defective and Unauthorized Work
(October 1, 2005 APWA GSP)
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 in
the written notice, with Contracting Agency forces or by such other means as the 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
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 monies due, or
to become due, the Contractor. Such direct and indirect costs shall include in particular, but
without limitation, compensation for additional professional services required, and costs for
repair and replacement of work of others destroyed or damaged by correction, removal, or
replacement of the Contractor’s unauthorized work.
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
provided by this Section.
The rights exercised under the provisions of this section shall not diminish the Contracting
Agency’s right to pursue any other avenue for additional remedy or damages with respect to the
Contractor’s failure to perform the work as required.
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
19
Contractor to determine the status of completion. The Engineer may also establish the
Substantial Completion Date unilaterally.
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.
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
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
20
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 aƯect a manufacturer’s
guaranties or warranties furnished under the terms of the contract.

correspondence from the Contractor constituting any notification, notice of protest, notice of
dispute, or other correspondence constituting notification required to be furnished under the
Contract, must be written in paper format, hand delivered or sent via certified mail delivery
service with return receipt requested to the Engineer's oƯice. Electronic copies such as e-mails
or electronically delivered copies of correspondence will not constitute such notice and will not
comply with the requirements of the Contract.

10.Notations to explain inspections, testing, stake-out, and all other services furnished by
Contracting Agency or other party during each working day on-site.
11.Entries to verify the daily (including non-working days) inspection and maintenance of
traƯic control devices and condition of the traveled roadway surfaces. Contractor shall not
allow any conditions to develop that would be hazardous to the public.
12.Any other information that serves to give an accurate and complete record of the nature,
quantity, and quality of Contractor’s progress on each day.
13.Plan markups showing locations and dimensions of constructed features to be used by
Engineer to produce record drawings.
14.All pages of the diary must be numbered consecutively with no omissions in page numbers.
15.Each page must be signed and dated by the Contractor’s oƯicial representative on the
project.
Contractor may use additional sheets separate from the diary book if necessary to provide a
complete diary record, but they must be signed, dated, and labeled with project name and
number.
It is expressly agreed between Contractor and Contracting Agency that the Daily Diary
maintained by Contractor shall be the “Contractor’s Book of Original Entry” for the
documentation of any potential claims or disputes that might arise during this Contract. Failure
of the Contractor to maintain this Diary in the manner described above will constitute a waiver
of any such claims or disputes by Contractor.
Engineer or Contracting Agency’s representative on-site will also complete an Inspector Daily
Report (IDR) for each day work is performed.
Payment
22
All costs to comply with this special provision are incidental to the contract and are the
responsibility of the Contractor. The Contractor shall include all related costs in the associated
bid prices of the contract.
1-05.18 Record Drawings
(March 8, 2013 APWA GSP)
Section 1-05.18 is an added new section:
The Contractor shall maintain one set of full size plans for Record Drawings, updated with clear

of information that a change in Work has occurred. The Contractor shall not conceal any work
until the required information is recorded.
This Record Drawing set shall be used for this purpose alone, shall be kept separate from other
Plan sheets, and shall be clearly marked as Record Drawings. These Record Drawings shall be
kept on site at the Contractor’s field oƯice, and shall be available for review by the Contracting
Agency at all times. The Contractor shall bring the Record Drawings to each progress meeting
for review.
The preparation and upkeep of the Record Drawings is to be the assigned responsibility of a
single, experienced, and qualified individual. The quality of the Record Drawings, in terms of
accuracy, clarity, and completeness, is to be adequate to allow the Contracting Agency to
modify the computer-aided drafting (CAD) Contract Drawings to produce a complete set of
Record Drawings for the Contracting Agency without further investigative eƯort by the
Contracting Agency.

1-07.2 State Taxes
Delete this section, including its sub-sections, in its entirety and replace it with the following:
1-07.2 State Sales Tax
(June 27, 2011 APWA GSP)
The Washington State Department of Revenue has issued special rules on the State sales tax.
Sections 1-07.2(1) through 1-07.2(3) are meant to clarify those rules. The Contractor should
contact the Washington State Department of Revenue for answers to questions in this area.
The Contracting Agency will not adjust its payment if the Contractor bases a bid on a
misunderstood tax liability.
The Contractor shall include all Contractor-paid taxes in the unit bid prices or other contract
amounts. In some cases, however, state retail sales tax will not be included. Section 1-07.2(2)
describes this exception.
The Contracting Agency will pay the retained percentage (or release the Contract Bond if a
FHWA-funded Project) only if the Contractor has obtained from the Washington State
Department of Revenue a certificate showing that all contract-related taxes have been paid
(RCW 60.28.051). The Contracting Agency may deduct from its payments to the Contractor any
amount the Contractor may owe the Washington State Department of Revenue, whether the
amount owed relates to this contract or not. Any amount so deducted will be paid into the
proper State fund.
1-07.2(1) State Sales Tax — Rule 171
WAC 458-20-171, and its related rules, apply to building, repairing, or improving streets, roads,
etc., which are owned by a municipal corporation, or political subdivision of the state, or by the
United States, and which are used primarily for foot or vehicular traffic. This includes storm or
combined sewer systems within and included as a part of the street or road drainage system
and power lines when such are part of the roadway lighting system. For work performed in
such cases, the Contractor shall include Washington State Retail Sales Taxes in the various
unit bid item prices, or other contract amounts, including those that the Contractor pays on the
purchase of the materials, equipment, or supplies used or consumed in doing the work.
1-07.2(2) State Sales Tax — Rule 170
WAC 458-20-170, and its related rules, apply to the constructing and repairing of new or
existing buildings, or other structures, upon real property. This includes, but is not limited to,
the construction of streets, roads, highways, etc., owned by the state of Washington; water
mains and their appurtenances; sanitary sewers and sewage disposal systems unless such
28
sewers and disposal systems are within, and a part of, a street or road drainage system;
telephone, telegraph, electrical power distribution lines, or other conduits or lines in or above
streets or roads, unless such power lines become a part of a street or road lighting system; and
installing or attaching of any article of tangible personal property in or to real property, whether
or not such personal property becomes a part of the realty by virtue of installation.
For work performed in such cases, the Contractor shall collect from the Contracting Agency,
retail sales tax on the full contract price. The Contracting Agency will automatically add this
sales tax to each payment to the Contractor. For this reason, the Contractor shall not include
the retail sales tax in the unit bid item prices, or in any other contract amount subject to Rule
170, with the following exception.
Exception: The Contracting Agency will not add in sales tax for a payment the Contractor or a
subcontractor makes on the purchase or rental of tools, machinery, equipment, or consumable
supplies not integrated into the project. Such sales taxes shall be included in the unit bid item
prices or in any other contract amount.
1-07.2(3) Services
The Contractor shall not collect retail sales tax from the Contracting Agency on any contract
wholly for professional or other services (as defined in Washington State Department of
Revenue Rules 138 and 244).
1-07.9(1) General
Section 1-07.9(1) is supplemented with the following:
(January 10, 2022 WSDOT GSP Option 1)
The Federal wage rates incorporated in this contract have been established by the
Secretary of Labor under United States Department of Labor General Decision No.
WA20220001.
The State rates incorporated in this contract are applicable to all construction activities
associated with this contract.
1-07.9(5)A Required Documents
(July 8, 2024 APWA GSP)
This section is revised to read as follows:
All Statements of Intent to Pay Prevailing Wages, Affidavits of Wages Paid and Certified
Payrolls, including a signed Statement of Compliance for Federal-aid projects, shall be
submitted to the Engineer and to the State L&I online Prevailing Wage Intent & Affidavit (PWIA)
system. When apprenticeship is a requirement of the contract, include in PWIA all
apprentices.

31
coverage shall be maintained by the Contractor for a minimum of 36 months following the

provide the Contracting Agency with proof of renewal. If renewal of the claims made form of
coverage becomes unavailable, or economically prohibitive, the Contractor shall purchase
an extended reporting period (“tail”) or execute another form of guarantee acceptable to the
Contracting Agency to assure financial responsibility for liability for services performed.
D. The Contractor’s Automobile Liability, Commercial General Liability and Excess or Umbrella

notice of any policy cancellation, within two business days of their receipt of such notice.
F. The Contractor shall not begin work under the Contract until the required insurance has

Contract or, at its discretion, procure or renew such insurance and pay any and all
premiums in connection therewith, with any sums so expended to be repaid to the
Contracting Agency on demand, or at the sole discretion of the Contracting Agency, oƯset
against funds due the Contractor from the Contracting Agency.
H. All costs for insurance shall be incidental to and included in the unit or lump sum prices of
the Contract and no additional payment will be made.
I.Under no circumstances shall a wrap up policy be obtained, for either initiating or
maintaining coverage, to satisfy insurance requirements for any policy required under this

policy for liability arising out of that specified or designated project.
1-07.18(2) Additional Insured
All insurance policies, with the exception of Workers Compensation, and of Professional
Liability and Builder’s Risk (if required by this Contract) shall name the following listed entities

endorsements shall be at least as broad as ISO forms CG 20 10 10 01 for ongoing operations
and CG 20 37 10 01 for completed operations.
1-07.18(3) Subcontractors

construed as a waiver of Contractor’s obligation to maintain such insurance.
Verification of coverage shall include:
1. An ACORD certificate or a form determined by the Contracting Agency to be equivalent.
2. Copies of all endorsements naming Contracting Agency and all other entities listed in
1-07.18(2) as additional insured(s), showing the policy number. The Contractor may submit

33
4. A notation of coverage enhancements on the Certificate of Insurance shall not satisfy these
requirements – actual endorsements must be submitted.
Upon request by the Contracting Agency, the Contractor shall forward to the Contracting
Agency a full and certified copy of the insurance policy(s). If Builders Risk insurance is required
on this Project, a full and certified copy of that policy is required when the Contractor delivers
the signed Contract for the work.
1-07.18(5) Coverages and Limits
The insurance shall provide the minimum coverages and limits set forth below. Contractor’s

construed to limit the liability of the Contractor to the coverage provided by such insurance, or
otherwise limit the Contracting Agency’s recourse to any remedy available at law or in equity.
All deductibles and self-insured retentions must be disclosed and are subject to approval by
the Contracting Agency. The cost of any claim payments falling within the deductible or self-

endorsements.
34

1-07.24 Rights of Way
(April 22, 2025 APWA GSP)
Delete this section and replace it with the following:
Street Right of Way lines, limits of easements, and limits of construction permits are indicated
in the Plans. The Contractor’s construction activities shall be confined within these limits
unless arrangements for use of private property are made as described below.
Generally, the Contracting Agency will have obtained, prior to bid opening, all rights of way and
easements, both permanent and temporary, necessary for carrying out the work. Exceptions to
this are noted in the Bid Documents or will be brought to the Contractor’s attention by a duly
issued Addendum.
Whenever any of the work is accomplished on or through property other than public Right of
Way, the Contractor shall meet and fulfill all covenants and stipulations of any easement
agreement obtained by the Contracting Agency from the owner of the private property. Copies
of the easement agreements may be included in the Contract Provisions or made available to
the Contractor as soon as practical after they have been obtained by the Engineer.
Whenever easements or rights of entry have not been acquired prior to advertising, these areas
are so noted in the Plans. The Contractor shall not proceed with any portion of the work in
areas where right of way, easements or rights of entry have not been acquired until the Engineer
certifies to the Contractor that the right of way or easement is available or that the right of entry
has been received. If the Contractor is delayed due to acts of omission on the part of the
Contracting Agency in obtaining easements, rights of entry or right of way, the Contractor will
be entitled to an extension of time. The Contractor agrees that such delay shall not be a breach
of contract.
Each property owner shall be given 48 hours’ notice prior to entry by the Contractor. This
includes entry onto easements and private property where private improvements must be
adjusted.
The Contractor shall be responsible for providing, without expense or liability to the Contracting
Agency, any additional land and access thereto that the Contractor may desire for temporary
construction facilities, storage of materials, or other Contractor needs. However, before using
any private property, whether adjoining the work or not, the Contractor shall file with the
Engineer a written permission of the private property owner, and, upon vacating the premises, a
written release from the property owner of each property disturbed or otherwise interfered with
by reasons of construction pursued under this contract. The statement shall be signed by the
private property owner, or proper authority acting for the owner of the private property affected,
stating that permission has been granted to use the property and all necessary permits have
been obtained or, in the case of a release, that the restoration of the property has been
35
satisfactorily accomplished. The statement shall include the parcel number, address, and
date of signature. Written releases must be filed with the Engineer before the Completion Date
will be established.

1-08.5 Time for Completion
(November 25, 2024 APWA GSP, Option A)
Revise the third and fourth paragraphs to read:
Contract time shall begin on the first working day following the Notice to Proceed Date.
Each working day shall be charged to the contract as it occurs, until the contract work is
physically complete. If substantial completion has been granted and all the authorized working
days have been used, charging of working days will cease. Each week the Engineer will provide
the Contractor a statement that shows the number of working days: (1) charged to the contract
the week before; (2) specified for the physical completion of the contract; and (3) remaining for
the physical completion of the contract. The statement will also show the nonworking days and
all partial or whole days the Engineer declares as unworkable The statement will be identified
as a Written Determination by the Engineer. If the Contractor does not agree with the Written
Determination of working days, the Contractor shall pursue the protest procedures in
accordance with Section 1-04.5. By failing to follow the procedures of Section 1-04.5, the
Contractor shall be deemed as having accepted the statement as correct. If the Contractor is
approved to work 10 hours a day and 4 days a week (a 4-10 schedule) and the fifth day of the
week in which a 4-10 shift is worked would ordinarily be charged as a working day then the fifth
39
day of that week will be charged as a working day whether or not the Contractor works on that
day.
Revise the sixth paragraph to read:
The Engineer will give the Contractor written notice of the completion date of the contract after
all the Contractor’s obligations under the contract have been performed by the Contractor. The
following events must occur before the Completion Date can be established:
1. The physical work on the project must be complete; and
2. The Contractor must furnish all documentation required by the contract and required by

Supplement this section with the following:
41
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 the Engineer.
1-09.9 Payments
(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 cutoƯ 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:
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.
42
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 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 aƯect the Work under the Contract.
Payment to the Contractor of partial estimates, final estimates, and retained percentages
shall be subject to controlling laws.

safe for access by Inspectors. The plant shall also be equipped with an approved dial-scale
thermometer, a mercury actuated thermometer, an electric pyrometer, or another approved
thermometric instrument placed at the discharge chute of the drier to automatically register
or indicate the temperature of the heated aggregates. This device shall be in full view of the
plant operator.
3.Heating of Asphalt Binder – The temperature of the asphalt binder shall not exceed the
maximum recommended by the asphalt binder manufacturer nor shall it be below the
minimum temperature required to maintain the asphalt binder in a homogeneous state. The
asphalt binder shall be heated in a manner that will avoid local variations in heating. The
heating method shall provide a continuous supply of asphalt binder to the mixer at a uniform
average temperature with no individual variations exceeding 25°F. Also, when a WMA
additive is included in the asphalt binder, the temperature of the asphalt binder shall not
exceed the maximum recommended by the manufacturer of the WMA additive.
4.Sampling and Testing of Mineral Materials – The HMA plant shall be equipped with a

will be required. Lines 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, 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.
55
If the paving machine in use is not providing the required finish, the Engineer may suspend Work

for the use of that roller for compaction of HMA. The number and weight of rollers shall be
sufficient to compact the mixture in compliance with the requirements of Section 5-04.3(10). The
use of equipment that results in crushing of the 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
56
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 pavement
shall be clean. All fatty asphalt patches, grease drippings, and other objectionable matter shall

small depressions shall be filled with an appropriate class of HMA. The surface of the patched
area shall be leveled and compacted thoroughly. Prior to 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.
All utility appurtenances (e.g. manhole covers, valve covers, etc.) located within the paving limits
shall be coated with a biodegradable soap to prevent the tack coat and HMA from sticking to
them. Diesel shall not be used for this purpose. After application of the biodegradable soap, all
catch basins shall be covered to prevent tack and HMA from entering into them.

5-04.3(4)A1 General
When the Proposal includes a pay item for crack sealing, seal all cracks ¼ inch in width and
greater.
Cleaning : Ensure that cracks are thoroughly clean, dry and free of all loose and foreign material
when filling with crack sealant material. Use a hot compressed air lance to dry and warm the
pavement surfaces within the crack immediately prior to filling a crack with the sealant material.
Do not overheat pavement. Do not use direct flame dryers. Routing cracks is not required.
Sand Slurry: For cracks that are to be filled with sand slurry, thoroughly mix the components and
pour the mixture into the cracks until full. Add additional CSS-1 cationic emulsified asphalt to
the sand slurry as needed for workability to ensure the mixture will completely fill the cracks.
Strike off the sand slurry flush with the existing pavement surface and allow the mixture to cure.
Top off cracks that were not completely filled with additional sand slurry. Do not place the HMA
overlay until the slurry has fully cured.
The sand slurry shall consist of approximately 20 percent CSS-1 emulsified asphalt,
approximately 2 percent portland cement, water (if required), and the remainder clean Class 1
or 2 fine aggregate per section 9-03.1(2). The components shall be thoroughly mixed and then
poured into the cracks and joints until full. The following day, any cracks or joints that are not
completely filled shall be topped off with additional sand slurry. After the sand slurry is placed,
the filler shall be struck off flush with the existing pavement surface and allowed to cure. The
HMA overlay shall not be placed until the slurry has fully cured. The requirements of Section 1-
06 will not apply to the portland cement and sand used in the sand slurry.
In areas where HMA will be placed, use sand slurry to fill the cracks.
In areas where HMA will not be placed, fill the cracks as follows:
1. Cracks ¼ inch to 1 inch in width - fill with hot poured sealant.
2. Cracks greater than 1 inch in width – fill with sand slurry.
Hot Poured Sealant: For cracks that are to be filled with hot poured sealant, apply the material
in accordance with these requirements and the manufacturer’s recommendations. Furnish a
Type 1 Working Drawing of the manufacturer’s product information and recommendations to the
Engineer prior to the start of work, including the manufacturer’s recommended heating time and
temperatures, allowable storage time and temperatures after initial heating, allowable reheating
criteria, and application temperature range. Confine hot poured sealant material within the
crack. Clean any overflow of sealant from the pavement surface. If, in the opinion of the Engineer,
the Contractor’s method of sealing the cracks with hot poured sealant results in an excessive
amount of material on the pavement surface, stop and correct the operation to eliminate the
excess material.
5-04.3(4)A2 Crack Sealing Areas Prior to Paving
In areas where HMA will be placed, use sand slurry to fill the cracks.

5-04.3(6) Mixing
After the required amount of mineral materials, asphalt binder, recycling agent and anti-stripping
additives have been introduced into the mixer the HMA shall be mixed until complete and
uniform coating of the particles and thorough distribution of the asphalt binder throughout the
mineral materials is ensured.
When discharged, the temperature of the HMA shall not exceed the optimum mixing temperature
by more than 25°F as shown on the reference mix design report or as approved by the Engineer.
Also, when a WMA additive is included in the manufacture of HMA, the discharge temperature of
the HMA shall not exceed the maximum recommended by the manufacturer of the WMA
additive. A maximum water content of 2 percent in the mix, at discharge, will be allowed
providing the water causes no problems with handling, stripping, or flushing. If the water in the
HMA causes any of these problems, the moisture content shall be reduced as directed by the
Engineer.
Storing or holding of the HMA in approved storage facilities will be permitted with approval of the
Engineer, but in no event shall the HMA be held for more than 24 hours. HMA held for more than
24 hours after mixing shall be rejected. Rejected HMA shall be disposed of by the Contractor at
no expense to the Contracting Agency. The storage facility shall have an accessible device
located at the top of the cone or about the third point. The device shall indicate the amount of
material in storage. No HMA shall be accepted from the storage facility when the HMA in storage
is below the top of the cone of the storage facility, except as the storage facility is being emptied
at the end of the working shift.
Recycled asphalt pavement (RAP) utilized in the production of HMA shall be sized prior to
entering the mixer so that a uniform and thoroughly mixed HMA is produced. If there is evidence
of the recycled asphalt pavement not breaking down during the heating and mixing of the HMA,
the Contractor shall immediately suspend the use of the RAP until changes have been approved
by the Engineer. After the required amount of mineral materials, RAP, new asphalt binder and
asphalt rejuvenator have been introduced into the mixer the HMA shall be mixed until complete
and uniform coating of the particles and thorough distribution of the asphalt binder throughout
the mineral materials, and RAP is ensured.

HMA Class 1”0.35 feet
HMA Class ¾” and HMA Class ½”
wearing course 0.30 feet
other courses 0.35 feet
HMA Class ⅜”0.15 feet
On areas where irregularities or unavoidable obstacles make the use of mechanical spreading
and finishing equipment impractical, the paving may be done with other equipment or by hand.
60
When more than one JMF is being utilized to produce HMA, the material produced for each JMF
shall be placed by separate spreading and compacting equipment. The intermingling of HMA
produced from more than one JMF is prohibited. Each strip of HMA placed during a work shift
shall conform to a single JMF established for the class of HMA specified unless there is a need to
make an adjustment in the JMF.
All cast off rock from raking shall be removed prior to compaction of final HMA lift.
5-04.3(8) Aggregate Acceptance Prior to Incorporation in HMA
For HMA accepted by nonstatistical evaluation the aggregate properties of sand equivalent,
uncompacted void content and fracture will be evaluated in accordance with Section 3-04.
Sampling and testing of aggregates for HMA accepted by commercial evaluation will be at the
option of the Engineer.
5-04.3(9) HMA Mixture Acceptance
Acceptance of HMA shall be as provided under nonstatistical, or commercial evaluation.
Nonstatistical evaluation will be used for the acceptance of HMA unless Commercial Evaluation
is specified.
Commercial evaluation will be used for Commercial HMA and for other classes of HMA in the
following applications: sidewalks, road approaches, ditches, slopes, paths, trails, gores,
prelevel, temporary pavement, and pavement repair. Other nonstructural applications of HMA
accepted by commercial evaluation shall be as approved by the Engineer. Sampling and testing
of HMA accepted by commercial evaluation will be at the option of the Engineer.
The mix design will be the initial JMF for the class of HMA. The Contractor may request a change
in the JMF. Any adjustments to the JMF will require the approval of the Engineer and may be made
in accordance with this section.
HMA Tolerances and Adjustments
1.Job Mix Formula Tolerances – The constituents of the mixture at the time of acceptance
shall be within tolerance. The tolerance limits will be established as follows:
For Asphalt Binder and Air Voids (Va), the acceptance limits are determined by adding
the tolerances below to the approved JMF values. These values will also be the Upper
Specification Limit (USL) and Lower Specification Limit (LSL) required in Section 1-
06.2(2)D2.

5-04.3(9)A Vacant
5-04.3(9)B Vacant
5-04.3(9)C Mixture Acceptance – Nonstatistical Evaluation
HMA mixture which is accepted by Nonstatistical Evaluation will be evaluated by the Contracting
Agency by dividing the HMA tonnage into lots.
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.
62
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 three samples
shall to be tested.
Sampling and testing HMA in a Structural application where quantities are less than 400 tons is
at the discretion of the Engineer.
For HMA used in a structural application and with a total project quantity less than 800 tons but
more than 400 tons, a minimum of one acceptance test shall be performed. In all cases, a
minimum of 3 samples will be obtained at the point of acceptance, a minimum of one of the three
samples will be tested for conformance to the JMF:
• If the test results are found to be within specification requirements, additional testing will be
at the Engineer’s discretion.
• If test results are found not to be within specification requirements, additional testing of the
remaining samples to determine a Composite Pay Factor (CPF) shall be performed.
5-04.3(9)C3 Mixture Nonstatistical Evaluation – Acceptance Testing
Testing of HMA for compliance of Va will at the option of the Contracting Agency. If tested,
compliance of Va will use WSDOT SOP 731. Testing of HMA for compliance of Va will not be
performed by the Contracting Agency for this contract.
Testing for compliance of asphalt binder content will be by WSDOT FOP for AASHTO T 308.
Testing for compliance of gradation will be by FOP for WAQTC T 27/T 11.
5-04.3(9)C4 Mixture Nonstatistical Evaluation – Pay Factors
For each lot of material falling outside the tolerance limits in 5-04.3(9), the Contracting Agency
will determine a Composite Pay Factor (CPF) using the following price adjustment factors:

Each lot of HMA produced under Nonstatistical Evaluation and having all constituents falling
within the tolerance limits of the job mix formula shall be accepted at the unit Contract price with
no further evaluation. When one or more constituents fall outside the nonstatistical tolerance
limits in the Job Mix Formula shown in Table of Price Adjustment Factors, the lot shall be
evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The
nonstatistical tolerance limits will be used in the calculation of the CPF and the maximum CPF
shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or
samples from the Roadway shall be tested to provide a minimum of three sets of results for
evaluation.
5-04.3(9)C5 Vacant
5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adjustments
For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated CPF is
less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the
algebraic difference of CPF minus 1.00 multiplied by 60 percent. The total job mix compliance
price adjustment will be calculated as the product of the NCMF, the quantity of HMA in the lot in
tons, and the unit Contract price per ton of mix.
If a constituent is not measured in accordance with these Specifications, its individual pay factor
will be considered 1.00 in calculating the Composite Pay Factor (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
64
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 Composite Pay Factor (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 Composite Pay Factor (CPF) of
not less than 0.75 when evaluated in accordance with Section 1-06.2, using a LSL of 92.0
(minimum of 92 percent of the maximum density). The maximum density shall be determined by
WSDOT FOP for AASHTO T 729. The specified level of density attained will be determined by the
evaluation of the density of the pavement. The density of the pavement shall be determined in
accordance with WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the
discretion of the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when
using cores to determine density.
Tests for the determination of the pavement density will be taken in accordance with the required
procedures for measurement by a nuclear density gauge or roadway cores after completion of
the finish rolling.
If the Contracting Agency uses a nuclear density gauge to determine density the test procedures
FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the mix is placed and prior
to opening to traffic.
Roadway cores for density may be obtained by either the Contracting Agency or the Contractor
in accordance with WSDOT SOP 734. The core diameter shall be 4-inches minimum, unless
otherwise approved by the Engineer. Roadway cores will be tested by the Contracting Agency in
accordance with WSDOT FOP for AASHTO T 166.
If the Contract includes the Bid item “Roadway Core” the cores shall be obtained by the
Contractor in the presence of the Engineer on the same day the mix is placed and at locations
designated by the Engineer. If the Contract does not include the Bid item “Roadway Core” the
Contracting Agency will obtain the cores.
65
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.
5-04.3(10)A HMA Compaction – General Compaction Requirements
Compaction shall take place when the mixture is in the proper condition so that no undue
displacement, cracking, or shoving occurs. Areas inaccessible to large compaction equipment
shall be compacted by other mechanical means. Any HMA that becomes loose, broken,
contaminated, shows an excess or deficiency of asphalt, or is in any way defective, shall be
removed and replaced with new hot mix that shall be immediately compacted to conform to the
surrounding area.
The type of rollers to be used and their relative position in the compaction sequence shall
generally be the Contractor’s option, provided the specified densities are attained. Unless the
Engineer has approved otherwise, rollers shall only be operated in the static mode when the
internal temperature of the mix is less than 175°F. Regardless of mix temperature, a roller shall
not be operated in a mode that results in checking or cracking of the mat.
On bridge decks and on roadway approaches within five feet of a bridge/back of pavement seat,
rollers shall not be operated in a vibratory mode, defined as a mode in which the drum vibrates
66
vertically. However, unless otherwise noted on the plans, rollers may be operated in an
oscillatory mode, defined as a mode in which the drum vibrates in the horizontal direction only.
Refer to contract drawings for HMA Paving Train requirements and restrictions (e.g. equipment
spacing, weight limits, etc.).
5-04.3(10)B HMA Compaction – Cyclic Density
Low cyclic density areas are defined as spots or streaks in the pavement that are less than 90
percent of the theoretical maximum density. At the Engineer’s discretion, the Engineer may
evaluate the HMA pavement for low cyclic density, and when doing so will follow WSDOT SOP
733. A $500 Cyclic Density Price Adjustment will be assessed for any 500-foot section with two
or more density readings below 90 percent of the theoretical maximum density.
5-04.3(10)C Vacant
5-04.3(10)D HMA Nonstatistical Compaction
5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots
HMA compaction which is accepted by nonstatistical evaluation will be based on acceptance
testing performed by the Contracting Agency dividing the project into compaction lots.
A lot is represented by randomly selected samples of the same mix design that will be tested for
acceptance. A lot is defined as the total quantity of material or work produced for each Job Mix
Formula placed. Only one lot per JMF is expected. A sublot shall be equal to one day’s production
or 400 tons, whichever is less except that the final sublot will be a minimum of 200 tons and may
be increased to 800 tons. Testing for compaction will be at the rate of 5 tests per sublot per
WSDOT T 738.
The sublot locations within each density lot will be determined by the Engineer. For a lot in
progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the
Engineer is satisfied that material conforming to the Specifications can be produced.
HMA mixture accepted by commercial evaluation and HMA constructed under conditions other
than those listed above shall be compacted on the basis of a test point evaluation of the
compaction train. The test point evaluation shall be performed in accordance with instructions
from the Engineer. The number of passes with an approved compaction train, required to attain
the maximum test point density, shall be used on all subsequent paving.
HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel ruts shall
be compacted with a pneumatic tire roller unless otherwise approved by the Engineer.
5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing
The location of the HMA compaction acceptance tests will be randomly selected by the Engineer
from within each sublot, with one test per sublot.
5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments
For each compaction lot with one or two sublots, having all sublots attain a relative density that
is 92 percent of the reference maximum density the HMA shall be accepted at the unit Contract
67
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.
5-04.3(11) Reject Work
5-04.3(11)A Reject Work General
Work that is defective or does not conform to Contract requirements shall be rejected. The
Contractor may propose, in writing, alternatives to removal and replacement of rejected
material. Acceptability of such alternative proposals will be determined at the sole discretion of
the Engineer. HMA that has been rejected is subject to the requirements in Section 1-06.2(2) and
this specification, and the Contractor shall submit a corrective action proposal to the Engineer
for approval.
5-04.3(11)B Rejection by Contractor
The Contractor may, prior to sampling, elect to remove any defective material and replace it with
new material. Any such new material will be sampled, tested, and evaluated for acceptance.
5-04.3(11)C Rejection Without Testing (Mixture or Compaction)
The Engineer may, without sampling, reject any batch, load, or section of Roadway that appears
defective. Material rejected before placement shall not be incorporated into the pavement. Any
rejected section of Roadway shall be removed.
No payment will be made for the rejected materials or the removal of the materials unless the
Contractor requests that the rejected material be tested. If the Contractor elects to have the
rejected material tested, a minimum of three representative samples will be obtained and
tested. Acceptance of rejected material will be based on conformance with the nonstatistical
acceptance Specification. If the CPF for the rejected material is less than 0.75, no payment will
be made for the rejected material; in addition, the cost of sampling and testing shall be borne by
the Contractor. If the CPF is greater than or equal to 0.75, the cost of sampling and testing will
be borne by the Contracting Agency. If the material is rejected before placement and the CPF is
greater than or equal to 0.75, compensation for the rejected material will be at a CPF of 0.75. If
rejection occurs after placement and the CPF is greater than or equal to 0.75, compensation for
the rejected material will be at the calculated CPF with an addition of 25 percent of the unit
Contract price added for the cost of removal and disposal.
68
5-04.3(11)D Rejection – A Partial Sublot
In addition to the random acceptance sampling and testing, the Engineer may also isolate from
a normal sublot any material that is suspected of being defective in relative density, gradation or
asphalt binder content. Such isolated material will not include an original sample location. A
minimum of three random samples of the suspect material will be obtained and tested. The
material will then be statistically evaluated as an independent lot in accordance with Section 1-
06.2(2).
5-04.3(11)E Rejection - An Entire Sublot
An entire sublot that is suspected of being defective may be rejected. When a sublot is rejected
a minimum of two additional random samples from this sublot will be obtained. These additional
samples and the original sublot will be evaluated as an independent lot in accordance with
Section 1-06.2(2).
5-04.3(11)F Rejection - A Lot in Progress
The Contractor shall shut down operations and shall not resume HMA placement until such time
as the Engineer is satisfied that material conforming to the Specifications can be produced:

continuous operation or as close to continuous as possible. Unscheduled transverse joints will
be allowed and the roller may pass over the unprotected end of the freshly laid mixture only when
the placement of the course must be discontinued for such a length of time that the mixture will
cool below compaction temperature. When the Work is resumed, the previously compacted
mixture shall be cut back to produce a slightly beveled edge for the full thickness of the course.
A temporary wedge of HMA constructed on a 20H:1V shall be constructed where a transverse
joint as a result of paving or planing is open to traffic. The HMA in the temporary wedge shall be
separated from the permanent HMA by strips of heavy wrapping paper or other methods
approved by the Engineer. The wrapping paper shall be removed and the joint trimmed to a
slightly beveled edge for the full thickness of the course prior to resumption of paving.

surface parallel to the centerline. The transverse slope of the completed surface of the wearing
70
course shall vary not more than ¼ inch in 10 feet from the rate of transverse slope shown in the
Plans.
When deviations in excess of the above tolerances are found that result from a high place in the
HMA, the pavement surface shall be corrected by one of the following methods:
1. Removal of material from high places by grinding with an approved grinding machine, or
2. Removal and replacement of the wearing course of HMA, or
3. By other method approved by the Engineer.
Correction of defects shall be carried out until there are no deviations anywhere greater than the
allowable tolerances.
Deviations in excess of the above tolerances that result from a low place in the HMA and
deviations resulting from a high place where corrective action, in the opinion of the Engineer, will
not produce satisfactory results will be accepted with a price adjustment. The Engineer shall
deduct from monies due or that may become due to the Contractor the sum of $500.00 for each
and every section of single traffic lane 100 feet in length in which any excessive deviations
described above are found.
When utility appurtenances such as manhole covers and valve boxes are located in the traveled
way, the utility appurtenances shall be adjusted to the finished grade prior to paving. This
requirement may be waived when requested by the Contractor, at the discretion of the Engineer
or when the adjustment details provided in the project plan or specifications call for utility
appurtenance adjustments after the completion of paving.

the information on the Agency website at: https://wsdot.wa.gov/business-wsdot/how-do-
business-us/public-works-contracts/payments-reporting/asphalt-binder-reference-cost. The
reference cost will be determined using posted prices furnished by Poten & Partners, Inc. If the
selected price source ceases to be available for any reason, then the Contracting Agency will
select a substitute price source to establish the reference cost.
Price adjustments will be calculated one time per month. No price adjustment will be made if
the Current Reference Cost is within +/-5% of the Base Cost. Reference costs for projects
located in Eastern versus Western Washington shall be selected from the column in the WSDOT
website table labeled “Eastern”, or “Western”, accordingly. The adjustment will be calculated
as follows:
If the reference cost is greater than or equal to 105% of the base cost, then

(Q x 0.056).
If the reference cost is less than or equal to 95% of the base cost, then
Asphalt Cost Price Adjustment = (Current Reference Cost – (0.95 x Base Cost)) x
(Q x 0.056).
Where:
Current Reference Cost is selected from the website table based on the “Date
Effective” that immediately precedes the current month’s progress estimate end
date. For work completed after all authorized working days are used, the adjustment
79
will be based on the posted reference cost during which contract time was
exhausted.
Base Cost is selected from the website table based on the “Date Effective” that
immediately precedes the contract bid opening date, and shall be a constant for all
monthly adjustments.
Q = total tons of all classes of HMA paid in the current month’s progress payment.
“Asphalt Cost Price Adjustment”, by calculation.
“Asphalt Cost Price Adjustment” will be calculated and paid for as described in this section.
