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

Contractor forces, in accordance with the intent of the Contract and without expense to the Owner, and
shall bear the expense of making good all Work of other contractors destroyed or damaged by such
removal or replacement.
If the Contractor does not remove such condemned Work and materials and commence re-execution of
the Work within 7 calendar days of written notice from the Engineer, or fails to perform any part of the
Work required by the Contract Documents, the Owner 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. In that case, the Owner may store removed material.
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

If sufficient funds do not remain in the Contract and the Contractor does not pay the cost of such removal
and storage within 10 calendar days from the date of the notice to the Contractor of the fact of such
removal, the Owner may, upon an additional 10 calendar days written notice, sell such materials at public
or private sale, and deduct all costs and expenses incurred from monies due to the Contractor, including
costs of sale, and accounting to Contractor for the net proceeds remaining. The Owner may bid at any
such sale. The Contractor shall be liable to the Owner for the amount of any deficiency from any funds
otherwise due the Contractor.
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
Special Provisions 33
of the Engineer, a delay in its remedy could be potentially unsafe, or might cause serious risk of loss or
damage to the public, the Property Owner and the Property Owner’s property.
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.
1-05.10 Guarantees
(Feb 3, 2025, Renton GSP)

unauthorized Work is discovered, the Contractor shall promptly, upon written order by the Contracting
Agency, return and in accordance with the Engineer’s instructions, either correct such Work, or if such
Work has been rejected by the Engineer, 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.”
The Contractor agrees the above one year limitation shall not exclude or diminish the Contracting
Agency’s rights under any law to obtain damages and recover costs resulting from defective and/or
unauthorized Work discovered after one year but prior to the expiration of the legal time period set
forth in RCW 4.16.040 limiting actions upon a contract 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 for, or
incorporated in the Work. Nothing contained in this paragraph, however, shall defeat 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.

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.
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
Special Provisions 35
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 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.

Work. This requirement shall apply continuously, and not be limited to normal working hours. The
required or implied duty of the Engineer to conduct construction review of the Contractor’s performance
does not, and shall not, be intended to include review and adequacy of the Contractor’s safety
measures, in, on, or near the project site.
1-07.2 State Tax
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)
1-07.2(1) General
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.
Special Provisions 41
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(2) 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(3) 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 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(4) 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).

The Contractor shall ensure that all necessary permits are obtained and is responsible for reviewing all
permits to become familiar with the requirements.
The Contractor and all subcontractors of any tier must obtain a City of Renton Business License
(Contractor).
The permits, easements, and right of entry documents that have been acquired are available for
inspection and review.
The Contractor shall be required to comply with all conditions of the permits, easements, and rights of
entry, at no additional cost to the Owner. The Contractor is required to indemnify the Owner from
claims on all easements and rights of entry.
All other permits, licenses, etc., shall be the responsibility of the Contractor. The Contractor shall comply
with the special provisions and requirements of each.
Permits, permission under franchises, licenses, and bonds of a temporary nature necessary for and
during the prosecution of the Work, and inspection fees in connection therewith shall be secured and
paid for by the Contractor. If the Owner is required to secure such permits, permission under franchises,
licenses and bonds, and pay the fees, the costs incurred by the Owner thereby shall be charged against
the Contractor and deducted from any funds otherwise due the Contractor.
The Contractor is cautioned to review all permits and other Contract Documents and schedule the work
activities appropriately to complete the work within the number of days stated in the Contract
Document. No additional compensation or extensions to time will be granted to the Contractor due to
the time constraints imposed by such documents. The Contractor shall assume all responsibility for
meeting all requirements of all permits.
Any fines or penalties incurred by Contracting Agency for not meeting state water quality standards
and/or lack of stormwater pollution prevention on this Project shall be deducted from monies otherwise
due to Contractor. Any fines assessed directly to Contractor shall be paid directly to the fining authority,
at the Contractor’s own cost.
1-07.9 Wages
1-07.9(3) Apprentices
(Feb 3, 2025 Renton GSP)
Section 1-07.9(3) is supplemented as follows:
Apprentice Utilization
This Contract includes an Apprentice Utilization Requirement. Fifteen percent or more of project Labor
Hours shall be performed by Apprentices unless Good Faith Efforts are accepted. Apprentice Utilization
will be determined using the Department of Labor and Industries (L&I) online Prevailing Wage Intent &
Affidavit (PWIA) system.
Special Provisions 43
Definitions
For the purposes of this specification the following definitions apply:
1. Apprentice is a person enrolled in a State-approved Apprenticeship Training Program.
2. Apprentice Utilization is the apprentice labor hours, on the project, expressed as a percentage of
project Labor Hours based on certified payrolls or the affidavits of wages paid, whichever is least.
The percentage is not rounded up.
3. Apprentice Utilization Requirement is the minimum percentage of apprentice labor hours
required by the Contract.
4. Good Faith Effort(s) (GFE) describes the Contractor’s efforts to meet the Apprentice Utilization
Requirement including but not limited to the specific steps as described elsewhere in this
specification.
5. Labor Hours are the total hours performed by all workers receiving an hourly wage who are
subject to prevailing wage requirements for work performed on the Contract as defined by RCW
39.04.310. Labor Hours are determined based on the scope of work performed by the individuals,
rather than the title of their occupations in accordance with WAC 296-127.
6. State-approved Apprenticeship Training Program is an apprenticeship training program approved
by the Washington State Apprenticeship Council.
7. Apprentice Wage Rates are the applicable wage rates that are to be paid for an apprentice
registered in a training program, separate from Journey Level rates, as set by the WashingtoState
Apprenticeship Training Council and Washington State Department of Labor and Industries (L&I).
Electronic Reporting
The Contractor shall use the PWIA System to submit the “Apprentice Utilization Plan”. Reporting
instructions are available in the application.
Apprentice Utilization Plan
The Contractor shall submit an “Apprentice Utilization Plan” by filling out the Apprentice Utilization Plan
Form (WSDOT Form 424-004) within 30 calendar days of execution, however no later than the
preconstruction meeting, demonstrating how and when they intend to achieve the Apprentice
Utilization Requirement. The Plan shall be in sufficient detail for the Engineer to track the Contractor’s
progress in meeting the utilization requirements. An Apprentice Utilization Plan shall be updated and
resubmitted as the Work progresses or when requested by the Engineer.
If the Contractor is unable to demonstrate the ability to meet the Apprentice Utilization Requirement with
their initial Apprentice Utilization Plan submission, an effort must be made to find additional registered
apprentices to perform on the contract. If after attempts have been made at every tier and every scope,
the Contractor must submit GFE documentation to the Contracting Agency. The Contractor shall actively
seek out opportunities to meet the Apprentice Utilization Requirement during the construction Work.
Contacts
The Contractor may obtain information on State-approved Apprenticeship Training Programs by using
the Apprentice Registration and Tracking System (ARTS) https://secure.lni.wa.gov/arts-public/#/program-
search or contacting the Department of Labor and Industries directly at:
Specialty Compliance and Services Division, Apprenticeship Section, P.O. Box 44530, Olympia, WA
98504-4530 or by phone at (360) 902-5320.
Compliance
The Contractor is expected to make attempts to employ Apprentices and shall include the requirement in
Special Provisions 44
any subcontracts at any tier. In the event that the Contractor is unable to achieve the Apprentice
Utilization Requirement, the Contractor shall submit GFE documentation demonstrating the efforts and
attempts they made. Final GFE documentation shall be submitted to the Contracting Agency after
Substantial Completion but no later than 30 days after Physical Completion.
If the Contractor fails to actively attempt to employ Apprentices, submit GFE documentation, or if the
Engineer does not approve the GFE, the Contractor will be assessed a penalty. The Engineer will provide
the Contractor with a written notice at Final Acceptance of the project informing the Contractor of the
failure to comply with this specification which will include a calculation of the penalty to be assessed as
provided for in the Payment section in this special provision.
If the Contractor achieves the required Apprentice Utilization an incentive will be assessed with Final
Payment.
Good Faith Efforts
The GFE shall document the attempts (efforts) the Contractor (and any subcontractor at any tier) made
to meet the Apprentice Utilization Requirement. Emails, letters, or other written communications with
letterhead, titles, and contact information are required.
Documentation must include one or more of the following accepted GFEs:
1. Demonstrated Lack of Availability of Apprentices. Correspondence from State-approved
Apprenticeship Training Program(s), with project specific responses confirming there is a lack of
availability of Apprentices for this project.
2. Demonstrated Disproportionate Ratio of Material/Equipment/Products to Labor Hours.
Documentation explaining the bid includes a disproportionate high cost of
material/equipment/products to Labor Hours. (E.g., a $2 M estimated contract includes $1 M or
more in procurement costs of equipment to be installed.)
3. Demonstrated Lack of Necessary Labor Hours. Correspondence from a State-approved Apprentice
Training Programs confirming there is not enough time in the project to meet required journey
level to apprentice training ratios.
4. Demonstrated Lack of Available Approved Programs. Correspondence from State-approved
Apprentice Training Programs, confirming there are no programs that train for the scopes
included/anticipated on the project. Contractor and state programs to submit training program
detail needs and details that could be used for future program creation.
5. Funding Precedent. Documentation that shows conflicting, more restrictive, or precedent
requirements for other training on the Project. Examples include, but are not limited to, Tribal
Employment Rights (TERO), Federal Training Hours, or Special Training that affect the ability to use
state-registered apprentices.
6. Warranty Work. Documentation from Original Equipment Manufacturers, or similar, confirming
that work performed must only be completed by certified journey-level installers or risk voiding
warranty, or similar.
Special Provisions 45
7. Other Effort. The Contractor may submit other evidence, documentation, or rationale for not
being able to achieve the required Apprentice Utilization that are not covered in the other efforts
named. Other efforts will still need to be corroborated by an independent, knowledgeable third-
party.
Contractors may receive a GFE credit for graduated Apprentice hours through the end of the calendar year
for all projects worked on as long as the Apprentice remains continuously employed with the same
Contractor/subcontractor they were working for when they graduated. If an Apprentice graduates during
employment on a project of significant duration, they may be counted towards a GFE credit for up to one
year after their graduation or until the end of the project (whichever comes first). Determination of
whether Contract requirements were met in good faith will be made by subtracting the hours from the
journeyman total reported hours for the project and adding them to the apprentice hour total. If the new
utilization percentage meets the Contract requirement, the Contractor will be reported as meeting the
requirement in good faith.
Approving Good Faith Efforts
The Contracting Agency will review submitted Good Faith Efforts and issue a determination. The Engineer
may request additional information, documentation, evidence or similar in order to approve such efforts.
A determination by the Engineer is final. The approved Good Faith Efforts will be loaded into the PWIA
system by the Contracting Agency.
Payment
Payment will be made for the following Bid Items:
“Apprenticeship Incentive”, by calculation
An incentive of $2,000.00 will be assessed with the Final Payment for Contractors who meet the
Apprentice Utilization Requirement without a reduction by Good Faith Effort. For the purpose of providing
a common proposal for all bidders, the Contracting Agency has entered an amount in the proposal to
become a part of the total bid by the Contractor.
“Apprenticeship Penalty”, by calculation.
Apprenticeship Hours will be measured for each hour of work performed by an apprentice as shown on
the Monthly Apprentice Utilization Report, based on certified payrolls or the affidavits of wages paid,
whichever is least. The percentage is not rounded up. For the purpose of providing a common proposal
for all bidders, the Contracting Agency has entered an amount in the proposal to become a part of the
total bid by the Contractor.
When the Contractor fails to meet the Apprenticeship goal of 15%, a penalty will be assessed for each
hour that is not achieved, unless a Good Faith Effort is approved by the Contracting Agency.
Special Provisions 46
Apprenticeship Utilization Penalty will be calculated as described below:
Apprentice
Utilization

Contractor is required to notify BP/Olympic Pipeline 48 hours in advance of excavation within 25ft of
high pressure petroleum pipelines.
Seattle Public Utilities (SPU)
Contractor is required to notify SPU 72 hours in advance of any excavation near SPU pipelines.
Utility Potholing
Potholing may be included as a bid item for use in determining the location of existing utilities in advance
of the Contractor's operations. If potholing is not included as a bid item then it shall be considered
Special Provisions 52
incidental to other Work. The Contractor shall submit all potholing requests to the Engineer for approval,
at least 2 working days before potholing is scheduled. Additionally, the Contractor shall provide potholing
at the Engineer's request.
In no way shall the Work described under Utility Potholing relieve the Contractor of any of the
responsibilities described in Section 1-07.17 of the Standard Specifications and Special Provisions, and
elsewhere in the Contract Documents.
Potholing shall include excavation and backfilling of the existing utility, identification of the pipe or line
size, material type and condition and the survey work to locate the facility horizontally and vertically.
Survey information to be obtained shall include station and offset to center of utility and elevation at top
of utility. Stations, offsets and elevations shall be to the nearest 0.1 foot unless greater accuracy is
required. Potholes shall be backfilled with CSBC compacted to 95%, or with controlled density fill (CDF),

(HMA) patch matching the depth of the surrounding pavement.
1-07.17(3) Site Specific Utility Potholing
(Feb 3, 2025, Renton GSP)
Section 1-07.17(3) is a new section:
Site Specific Utility Potholing is intended to be additional potholing as identified in the plans or as directed
by the Engineer, which is separate from and in addition to potholing included as incidental for utility
installation. The Contractor shall perform exploratory excavations as required to collect as-built
information. The Contractor shall verify the depth, location, alignment, size, and material of existing
underground utilities. The Contractor shall immediately notify the Engineer if field conditions differ from
the expected conditions shown in the Contract Drawings. The Contractor shall perform all potholing
identified on the plans prior to any construction to allow for any potential design modifications. The
Contractor is still responsible to verify depth, location, alignment, and size of all existing utilities either
specifically called for or not on the plans. For these utilities, the Contractor shall allow the Engineer 5
working days after written results are received to allow for minor design modifications when needed. The
Contractor shall use the information obtained by potholing for procurement of suitable materials to revise
the work accordingly, where required by the Contract. Upon completion of excavation the material can be
used for temporary restoration.
Where underground utilities are found to be in the way of construction, such condition shall not be
deemed to be a changed or differing site condition, and if necessary, pipe alignment or grade shall be
modified. No payment will be made unless potholing has been performed prior to trench excavation and
witnessed by the Engineer. Different utilities may be found to occupy a common trench. Any two or more
utilities separated by 3 feet or less shall constitute one locate. Where multiple utilities exist in close
proximity, the Contractor shall be paid for one locate for every 5 feet of exploration trench. The quantity
for this item is included to provide a common proposal for bid purposes. The actual quantity used in
construction may vary from that amount. The unit price will not be adjusted if the actual quantity used
varies by more than 25 percent.
The Contractor shall perform for this potholing a minimum of five working days prior to crossing to allow
for potential revisions. The Contractor shall not have cause for claim of down-time or any other additional
costs associated with ‘waiting’ if the owner provides design revisions (related to the information supplied
per this section) within three working days after the contractor provides the surveyed elevations.
Special Provisions 53
In no way shall the Work described under Site Specific Utility Potholing relieve the Contractor of any of
the responsibilities described in Section 1-07.17 of the Standard Specifications and Special Provisions, and
elsewhere in the Contract Documents.
1-07.17(4) Interruption of Services
(Feb 3, 2025, Renton GSP)
Section 1-07.17(4) is a new section:
Section 1-07.17(4) is a new section:
Whenever in the course of the construction operation it becomes necessary to cause an outage of utilities,
it shall be the Contractor's responsibility to notify the affected users and the Engineer not less than 48
hours in advance of such outage. The Contractor shall make reasonable effort to minimize the duration of
outages and shall estimate the length of time service will be interrupted and so notify the users. In the
case of any utility outage that has exceeded or will exceed four hours, user contact shall again be made.
Temporary service, if needed, will be arranged by the Contractor at no cost to the Owner.
Water service interruptions, shut-offs, and connections shall be in accordance with Section 7-09.
Overhead lighting outages shall not exceed 24 hours. All cost to the Contractor for providing temporary
overhead lighting to meet above requirements shall be incidental to the various unit and Lump sum items
of the Contract; no separate payment will be made.
In the event on an unplanned interruption of service, the Contractor shall be responsible for notifying the
utility owner and customer immediately. The Contractor shall be solely responsible for repairing any
broken utilities and/or services in a timely manner.
1-07.17(5) Resolution of Utility Conflicts
(Feb 3, 2025, Renton GSP)
Section 1-07.17(5) is a new section:
In no way shall the work described under Resolution of Utility Conflicts relieve Contractor of any of the
responsibilities described in Section 1-07.17 of the Standard Specifications and Special Provisions, and
elsewhere in the Contract Documents. If or when utility conflicts occur, Contractor shall continue the
construction process on other aspects of the project whenever possible.
If “Resolution of utility conflicts” is included as a bid item in Section 1-09.14, it shall be used to resolve any
new identified utility conflicts not otherwise shown on the Contract Drawing or Specifications that are
identified during the course of construction.
In the event that a conflict arises between the proposed improvements and an existing utility, the
Resolution of Utility Conflicts item will compensate the Contractor for standby time and additional work
in the following manner:
1. Standby time resulting from existing utility conflicts
a) Standby time is defined as time the Contractor is unable to proceed with progression of a specific
work item (i.e. storm drainage, underground utility installation etc.) due to conflicts with existing
facilities. However, payment for standby time shall be limited to:
Special Provisions 54
(1) For each agreed upon conflict, a maximum of four (4) hours of standby time will be paid for
actual delay of labor and equipment due to a utility conflict. The Contractor shall be
responsible to adjust his work schedule and/or reassign his work forces and equipment to
other areas of work to minimize standby time.
(2) If the conflict is resolved within one (1) hour of notification to the Engineer, no standby time
will be paid.
2. Additional work required to resolve utility conflicts will be paid for at the bid unit prices for the
associated work. Work that can be measured and paid for at the unit contract prices shall not be
identified as force account work. This work includes but is not limited to:
(1) Storm drainage manhole, pipe, vault, and conduit realignments of line and/or grade for the
storm drain, undergrounding of overhead utilities, illumination, and signal, to avoid existing
utility conflicts.
(2) Additional storm drainage manholes, pipe, vaults, and conduit required by a change in
alignment, and/or grade, not exceeding the limits set in Section 1-04.4 of the Standard
Specifications.
If “Resolution of Utility Conflicts” is included as a Bid Item in Section 1-09.14, it shall be used to resolve
any new identified utility conflicts not otherwise shown on the Contract Drawings or Specifications that
are identified during the course of construction.

of private property are made.
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

Where the Contractor elects to Work on a Saturday, Sunday, holiday, or longer than an 8-hour Work shift
on a regular working day, as defined in the Standard Specifications, such Work shall be considered as
overtime Work. On all such overtime Work an inspector will be present, and a survey crew may be
required at the discretion of the Engineer. The Contractor shall reimburse the Contracting Agency for the
full amount of the straight time plus overtime costs for employees and representative(s) of the
Contracting Agency required to work overtime hours.
The Contractor by these Specifications does hereby authorize the Engineer to deduct such costs from the
amount due or to become due the Contractor.
1-08.1 Subcontracting
(Feb 3, 2025, Renton GSP)
Section 1-08.1 is supplemented as follows:
Written requests for change in subcontractors shall be submitted by the Contractor to the Engineer at
least 7 calendar days prior to start of a subcontractor's Work.
The Contractor agrees that he/she is fully responsible to the Owner for the acts and omissions of all
subcontractors and lower-tier subcontractors, and persons either directly or indirectly employed by the
subcontractors, as well as for the acts and omissions of persons directly employed by the Contractor.
The Contractor shall be required to give personal attention to the Work that is sublet. Nothing contained
in the Contract Documents shall create any contractual relation between any subcontractor and the
Owner.
The Contractor shall be responsible for making sure all subcontractors submit all required
documentation, forms, etc.
1-08.3 Progress Schedule
(Feb 3, 2025, Renton GSP)
Delete this section and replace it with the following:
The progress schedule for the entire project shall be submitted 7 calendar days prior to the
Preconstruction Conference. The schedule shall be prepared using the critical path method (CPM),
preferably using Microsoft Project or equivalent software. The schedule shall contain this information, at
a minimum:
1. Construction activities, in sufficient detail that all activities necessary to construct a complete and
functional project are considered. Any activity that has a scheduled duration exceeding 30
calendar days shall be subdivided until no sub-element has a duration exceeding 30 calendar days.
2. The schedule shall clearly indicate the activities that comprise the critical path. For each activity
Special Provisions 67
not on the critical path, the schedule shall show the float, or slack, time.
3. Procurement of material and equipment.
4. Submittals requiring review by the Engineer. Submittal by the Contractor and review by the
Engineer shall be shown as separate activities.
5. Work to be performed by a subcontractor, agent, or any third party.
6. Allowances for delays that could result from normal inclement weather (time extensions due to
inclement weather will not be allowed).
7. Allowances for the time required by utilities (Owner’s and others) to locate, monitor, and adjust
their facilities as required.
The Engineer may request the Contractor to alter the progress schedule when deemed necessary in the
opinion of the Engineer, in the interest of public safety and welfare of the Owner, or for coordination with
any other activity of other contractors, the availability of all or portions of the job site, or special provisions
of this Contract, or to reasonably meet the completion date of the project. The Contractor shall provide
such revised schedule within 10 days of request.
If, at any time, in the opinion of the Engineer, the progress of construction falls significantly behind
schedule, the Contractor may be required to submit a plan for regaining progress and a revised schedule
indicating how the remaining Work items will be completed within the authorized contract time.
The Contractor shall promptly report to the Engineer any conditions that the Contractor feels will require
revision of the schedule and shall promptly submit proposed revisions in the progress schedule for
acceptance by the Engineer. When such changes are accepted by the Engineer, the revised schedule shall
be followed by the Contractor.
Weekly Schedule. The Contractor shall submit a weekly progress schedule to the Engineer which sets
forth specific Work to be performed the following week, and a tentative schedule for the second week.
Failure to Maintain Progress Schedule. The Engineer will check actual progress of the Work against the
progress schedule a minimum of two times per month. Failure, without just cause, to maintain progress
in accordance with the approved schedule shall constitute a breach of Contract. If, through no fault of the
Contractor, the proposed construction schedule cannot be met, the Engineer will require the Contractor
to submit a revised schedule to the Engineer for acceptance. The approved revisions will thereafter, in all
respects, apply in lieu of the original schedule.
Failure of the Contractor to follow the progress schedule submitted and accepted, including revisions
thereof, shall relieve the Owner of any and all responsibility for furnishing and making available all or any
portion of the job site, and will relieve the Owner of any responsibility for delays to the Contractor in the
performance of the Work.
The cost of preparing the progress schedule, any supplementary progress schedules, and weekly schedules
shall be considered incidental to the Contract and no other compensation shall be made.
Special Provisions 68
1-08.4 Prosecution of the Work
(July 23, 2015 APWA GSP)
Section 1-08.4 is replaced with the following:
Notice to Proceed will be given after the contract has been executed and the contract bond and
evidence of insurance have been approved and filed by the Contracting Agency. The Contractor shall not
commence with the work until the Notice to Proceed has been given by the Engineer. The Contractor
shall commence construction activities on the project site within ten days of the Notice to Proceed Date,
unless otherwise approved in writing. The Contractor shall diligently pursue the work to the physical
completion date within the time specified in the contract. Voluntary shutdown or slowing of operations
by the Contractor shall not relieve the Contractor of the responsibility to complete the work within the
time(s) specified in the contract.
When shown in the Plans, the first order of work shall be the installation of high visibility fencing to
delineate all areas for protection or restoration, as described in the Contract. Installation of high
visibility fencing adjacent to the roadway shall occur after the placement of all necessary signs and
traffic control devices in accordance with 1-10.1 (2). Upon construction of the fencing, the Contractor
shall request the Engineer to inspect the fence. No other work shall be performed on the site until the
Contracting Agency has accepted the installation of the high visibility fencing, as described in the
Contract.
1-08.5 Time For Completion
(Feb 3, 2025, Renton GSP)
The first five paragraphs of Section 1-08.5 are deleted and replaced with the following:
The Work shall be physically completed in its entirety within the time specified in the Contract
Documents or as extended by the Engineer. The Contract Time will be stated in “working days”, shall
begin on the Notice To Proceed date, or the date identified in the Notice to Proceed as “the first working
day”, and shall end on the Contract Completion date.
A non-working day is defined as a Saturday, a Sunday, a day on which the Contract specifically suspends
Work, or one of these holidays: January 1, third Monday of January, Memorial Day, Juneteenth, July 4,
Labor Day, November 11, Thanksgiving Day, the day after Thanksgiving, and Christmas Day. The day
before Christmas shall be a holiday when Christmas Day occurs on a Tuesday, Wednesday, or Friday.
The day after Christmas shall be a holiday when Christmas Day occurs on a Monday or Thursday. When
Christmas Day occurs on a Saturday, the two preceding working days shall be observed as holidays.
When Christmas day occurs on a Sunday, the two working days following shall be observed as holidays.
When holidays other than Christmas fall on a Saturday, the preceding Friday will be counted as a non-
working day and when they fall on a Sunday the following Monday will be counted as a non-working
day. The Contract Time has been established to allow for periods of normal inclement weather that,
from historical records, is to be expected during the Contract Time, and during which periods, Work is
anticipated to be performed. Each successive working day, beginning with the Notice to Proceed date
and ending with the Physical Completion date, shall be charged to the Contract Time as it occurs except
a day, or part of a day, which is designated a non-working day or an Engineer determined unworkable
day.
Special Provisions 69
The Engineer will furnish the Contractor a weekly report showing (1) the number of working days
charged against the Contract Time for the preceding week; (2) the Contract Time in working days; (3) the
number of working days remaining in the Contract Time; (4) the number of non-working days; and (5)
any partial or whole days the Engineer declared unworkable the previous week. This weekly report will
be correlated with the Contractor’s current approved progress schedule. If the Contractor elects 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 day of that week will be charged as
a working day whether or not the Contractor works on that day.
The Contractor will be allowed 10 calendar days from the date of each report in which to file a written
protest of an alleged discrepancy in the Contract Time as reported. Otherwise, the report will be
deemed to have been accepted by the Contractor as correct.
The requirements for scheduling the Final Inspection and establishing the Substantial Completion,
Physical Completion, and Completion Dates are specified in Sections 105.11 and 1-05.12.
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
law, to allow the Contracting Agency to process final acceptance of the contract. The following
documents must be received by the Project Engineer prior to establishing a completion date:
a. Certified Payrolls (per Section 1-07.9(5)).
b. Material Acceptance Certification Documents
c. Monthly Reports in DMCS of the amounts paid including the final payment confirmation
to all firms required by Section 1-08.1(7)A if applicable
d. Final Contract Voucher Certification
e. Copies of the approved “Affidavit of Prevailing Wages Paid” for the Contractor and all
subcontractors
f. A copy of the Notice of Termination sent to the Washington State Department of
Ecology (Ecology); the elapse of 30 calendar days from the date of receipt of the Notice of
Termination by Ecology; and no rejection of the Notice of Termination by Ecology. This
requirement will not apply if the Construction Stormwater General Permit is transferred back to
the Contracting Agency in accordance with Section 8-01.3(16).
g. Property owner releases per Section 1-07.24
Section 1-08.5 is supplemented as follows:
Within 10 calendar days after execution of the Contract by the Contracting Agency, the Contractor shall
Special Provisions 70
provide the Contracting Agency with copies of purchase orders for all equipment items deemed critical
by the Contracting Agency, including but not limited to signal controller materials, lighting standards,
and signal standards required for the physical completion of the Contract. Such purchase orders shall
disclose the estimated delivery dates for the equipment.
All items of Work that can be performed without delivery of the critical items shall start and be
completed as soon as possible. At that time, the Engineer may suspend the Work upon request of the
Contractor until the critical items are delivered to the Contractor, if the Contracting Agency received a
purchase order within 10 calendar days after execution of the Contract by the Contracting Agency.
The Contractor will be entitled to only one such suspension of time during the performance of the Work
and during such suspension shall not perform any additional Work on the project. Upon delivery of the
critical items, contract time will resume and continue to be charged in accordance with Section 1-08.
1-08.9 Liquidated Damages
(March 3, 2021 APWA GSP)
Revise the second and third paragraphs to read:
Accordingly, the Contractor agrees:
1. To pay (according to the following formula) liquidated damages for each working day
beyond the number of working days established for Physical Completion, and
2. To authorize the Engineer to deduct these liquidated damages from any money due or
coming due to the Contractor.
Liquidated Damages Formula
LD = 0.15 C / T
Where:
LD = liquidated damages per working day (rounded to the nearest dollar)
C = original Contract amount
T = original time for Physical Completion
When the Contract work has progressed to Substantial Completion as defined in the Contract, the
Engineer may determine the Contract Work is Substantially Complete. The Engineer will notify the
Contractor in writing of the Substantial Completion Date. For overruns in Contract time occurring after
the date so established, the formula for liquidated damages shown above will not apply. For overruns in
Contract time occurring after the Substantial Completion Date, liquidated damages shall be assessed on
the basis of direct engineering and related costs assignable to the project until the actual Physical
Completion Date of all the Contract Work. The Contractor shall complete the remaining Work as promptly
as possible. Upon request completing the physical Work on the Contract.
Special Provisions 71
1-08.11 Contractor's Plant and Equipment
(Feb 3, 2025, Renton GSP)
Section 1-08.11 is a new Section:
The Contractor alone shall at all times be responsible for the adequacy, efficiency, and sufficiency of his
and his subcontractor's plant and equipment. The Owner shall have the right to make use of the
Contractor's plant and equipment in the performance of any Work on the site of the Work.
The use by the Owner of such plant and equipment shall be considered as extra Work and paid for
accordingly.
Neither the Owner nor the Engineer assumes any responsibility, at any time, for the security of the site
from the time the Contractor's operations have commenced until final acceptance of the Work by the
Engineer and the Owner. The Contractor shall employ such measures as additional fencing, barricades,
and watchmen service, as he deems necessary for the public safety and for the protection of the site and
his plant and equipment. The Owner will be provided keys for all fenced, secured areas.
1-08.12 Attention to Work
(Feb 3, 2025, Renton GSP)
Section 1-08.12 is a new section:
The Contractor shall give his personal attention to and shall supervise the Work to the end that it shall
be prosecuted faithfully, and when he is not personally present on the Work site, he shall at all times be
represented by a competent superintendent who shall have full authority to execute the same, and to
supply materials, tools, and labor without delay, and who shall be the legal representative of the
Contractor. The Contractor shall be liable for the faithful observance of any instructions delivered to him
or to his authorized representative.
1-09 MEASUREMENT AND PAYMENT
1-09.1 Measurement of Quantities
(Feb 3, 2025, Renton GSP)
Section 1-09.1 is supplemented by adding the following:
Lump Sum. The percentage of lump sum Work completed, and payment will be based on the cost
percentage breakdown of the lump sum bid price(s) submitted at the preconstruction conference.
The Contractor shall submit a breakdown of costs for each lump sum bid item. The breakdown shall list
the items included in the lump sum together with a unit price of labor, materials, and equipment for each
item. The summation of the detailed unit prices for each item shall add up to the lump sum bid. The unit
price values may be used as a guideline for determining progress payments or deductions or additions in
payment for ordered Work changes.
Cubic Yard Quantities. The Contractor shall provide truck trip tickets for progress payments only in the
following manner. Where items are specified to be paid by the cubic yard, the following tally system shall
be used.
Special Provisions 72
All trucks to be employed on this Work will be measured to determine the volume of each truck. Each
truck shall be clearly numbered, to the satisfaction of the Engineer, and there shall be no duplication of
numbers.
Duplicate tally tickets shall be prepared to accompany each truckload of material delivered on the project.
All tickets received that do not contain the following information will not be processed for payment:
1 Truck number
2 Quantity and type of material delivered in cubic yards
3 Drivers name, date and time of delivery
4 Location of delivery, by street and stationing on each street
5 Place for the Engineer to acknowledge receipt
6 Pay item number
7 Contract number and/or name
It will be the Contractor's responsibility to see that a ticket is given to the Engineer on the project for each
truckload of material delivered. Pay quantities will be prepared on the basis of said tally tickets.
Loads will be checked by the Engineer to verify quantity shown on ticket.
Quantities by Ton. It will be the Contractor's responsibility to see that a certified weight ticket is given to
the Inspector on the project at the time of delivery of materials for each truckload delivered. Pay
quantities will be prepared on the basis of said tally tickets, delivered to Inspector at time of delivery of
materials. Tickets not receipted by Inspector will not be honored for payment.
Each truck shall be clearly numbered to the satisfaction of the Engineer and there shall be no duplication
of numbers.
Duplicate tickets shall be prepared to accompany each truckload of material delivered to the project. All
tickets received that do not contain the following information will not be processed for payment:
1. Truck number
2. Truck tare weight (stamped at source)
3. Gross truckload weight in tons (stamped at source)
4. Net load weight (stamped at source)
5. Driver's name, date, and time of delivery
6. Location for delivery by street and stationing on each street
7. Place for the Engineer to acknowledge receipt
8. Pay item number
9. Contract number and/or name
Special Provisions 73
1-09.3 Scope of Payment
(Feb 3, 2025, Renton GSP)
Section 1-09.3 is supplemented by adding the following:
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
(December 30, 2022 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.
Special Provisions 74
1-09.7 Mobilization
(Feb 3, 2025, Renton GSP)
Section 1-09.7 is supplemented as follows:
Mobilization shall also include, but not be limited to, the following items: the movement of Contractor's
personnel, equipment, supplies, and incidentals to 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.
Payment will be made for the following bid item(s):
“Mobilization & Demobilization,” Lump Sum.
1-09.9 Payments
Section 1-09.9 is revised as follows:
(******)
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 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 Engineer will make a
determination based on information available. The 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:
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.
Special Provisions 75
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.
Payments will be made by check or electronic transfer, issued by the Contracting Agency’s fiscal
officer, against the appropriate fund source for the project. Payments received on account of Work
performed by a subcontractor are subject to the provisions of RCW 39.04.250.
Failure to perform 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 affect the Work under the Contract.
Payment to the Contractor of partial estimates, final estimates, and retained percentages shall be
subject to controlling laws.
Section 1-09.9 is supplemented as follows:
Special Provisions 76
Applications for payment shall be itemized and supported to the extent required by the Engineer by
receipts or other vouchers showing payment for materials and labor, payments to subcontractors,
and other such evidence of the Contractor's right to payment as the Engineer may direct, including
“red line” as-built drawings showing work installed by the contractor during the progress payment
period.
The Contractor shall submit a progress report with each monthly request for a progress payment. The
progress report shall indicate the estimated percent complete for each activity listed on the progress
schedule (see Section 1-08.3) and a revised and updated schedule to reflect the most current project
completion date.
1-09.9(1) Retainage
(Feb 3, 2025, Renton GSP)
Section 1-09.9(1) is supplemented as follows:
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.
1-09.9(2) Contracting Agency’s Right to Withhold and Disburse Certain Amounts
(Feb 3, 2025, Renton GSP)
Section 1-09.9(2) is a new section:
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 1-08.0(3).
Special Provisions 77
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 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 1-05.4.
c. Failure of the Contractor to correct defective or unauthorized Work (Section 1-05.7).
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.
Special Provisions 78
1-09.9(3) Final Payment
(Feb 3, 2025, Renton GSP)
Section 1-09.9(3) is a new section:
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 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).

Rollers shall be of the steel wheel, vibratory, oscillatory, or pneumatic tire type, in good condition and
capable of reversing without backlash. Operation of the roller shall be in accordance with the
manufacturer’s recommendations. When ordered by the Engineer for any roller planned for use on
the project, the Contractor shall provide a copy of the manufacturer’s recommendation 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
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.
Special Provisions 131
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 be entirely
removed from the existing pavement. All pavements or bituminous surfaces shall be thoroughly
cleaned of dust, soil, pavement grindings, and other foreign matter. All holes and 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.

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
Special Provisions 132
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(4)A3 Crack Sealing Areas Not to be Paved

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
Special Provisions 134
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.
5-04.3(7) Spreading and Finishing

shall not exceed the following:
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.
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.
Special Provisions 135
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.
Property Non-Statistical Evaluation Commercial Evaluation
Asphalt Binder +/- 0.5% +/- 0.7%
Air Voids, Va 2.5% min. and 5.5% max N/A
For Aggregates in the mixture:
a. First, determine preliminary upper and lower acceptance limits by applying the
following tolerances to the approved JMF.
Aggregate Percent Passing Non-Statistical
Evaluation
Commercial

1”, ¾”, ½”, and 3/8” sieves +/- 6% +/- 8%
No. 4 sieve +/-6% +/- 8%
No. 8 Sieve +/- 6% +/-8%
No. 200 sieve +/- 2.0% +/- 3.0%
b. Second, adjust the preliminary upper and lower acceptance limits determined from
step (a) the minimum amount necessary so that none of the aggregate properties are
outside the control points in Section 9-03.8(6). The resulting values will be the upper
and lower acceptance limits for aggregates, as well as the USL and LSL required in
Section 1-06.2(2)D2.
2. Job Mix Formula Adjustments – An adjustment to the aggregate gradation or asphalt
binder content of the JMF requires approval of the Engineer. Adjustments to the JMF will
only be considered if the change produces material of equal or better quality and may
require the development of a new mix design if the adjustment exceeds the amounts
listed below.
a. Aggregates –2 percent for the aggregate passing the 1½″, 1″, ¾″, ½″, ⅜″, and the No.
4 sieves, 1 percent for aggregate passing the No. 8 sieve, and 0.5 percent for the
aggregate passing the No. 200 sieve. The adjusted JMF shall be within the range of
the control points in Section 9-03.8(6).

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.
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.
Special Provisions 137
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:
Table of Price Adjustment Factors
Constituent Factor “f”
All aggregate passing: 1½″, 1″, ¾″, ½″, ⅜″ and No.4 sieves 2
All aggregate passing No. 8 sieve 15
All aggregate passing No. 200 sieve 20
Asphalt binder 40
Air Voids (Va) (where applicable) 20
Each lot of HMA produced under Nonstatistical Evaluation and having all constituents falling within
the tolerance limits of the job mix formula shall be accepted at the unit Contract price with no further
evaluation. When one or more constituents fall outside the nonstatistical tolerance limits in the Job
Mix Formula shown in Table of Price Adjustment Factors, the lot shall be evaluated in accordance with
Section 1-06.2 to determine the appropriate CPF. The nonstatistical tolerance limits will be used in
the calculation of the CPF and the maximum CPF shall be 1.00. When less than three sublots exist,
backup samples of the existing sublots or samples from the Roadway shall be tested to provide a
minimum of three sets of results for evaluation.
5-04.3(9)C5 Vacant
5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adjustments
For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated CPF is less
than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the algebraic
difference of CPF minus 1.00 multiplied by 60 percent. The total job mix compliance price adjustment
will be calculated as the product of the NCMF, the quantity of HMA in the lot in tons, and the unit
Contract price per ton of mix.
If a constituent is not measured in accordance with these Specifications, its individual pay factor will
be considered 1.00 in calculating the Composite Pay Factor (CPF).
Special Provisions 138
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 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.
Special Provisions 139
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.
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.
Special Provisions 140
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)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.
Special Provisions 141
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.
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.

7-09.3(23) Hydrostatic Pressure Test
Section 7-09.3(23) is revised as follows:
(******)
All new water mains and appurtenances including water service connections to the meter setters shall be
tested in sections of convenient length under a hydrostatic pressure equal to 150 psi in excess of that
under which they will operate or in no case shall the test pressure be less than 225 psi at the highest point
on the water main. Pumps, gauges, plugs, saddles, corporation stops, miscellaneous hose and piping, and
measuring equipment necessary for performing the test shall be furnished and operated by the Contractor.
The Contractor shall obtain a hydrant meter permit from the City by completing a permit application and
making the required security deposits. The Contractor shall use the City’s issued hydrant meter with an
attached backflow prevention assembly to draw water from the City’ water system to fill the water mains
for poly-pigging, testing, cleaning, disinfection and for subsequent flushing purposes. There will be a
charge for the water used for filling, testing, cleaning and disinfection of the water mains.
Sections to be tested shall normally be limited to 1,500 feet or less. The Engineer may require that the first
section of pipe, not less than 1,000 feet in length, installed by each of the Contractor’s crews, be tested in
order to qualify the crew and the materials. Pipe laying shall not be continued more than an additional
1,000 feet until the first section has been tested successfully.
The pipeline shall be backfilled sufficiently to prevent movement of the pipe under pressure. Thrust blocks
shall be in place and time allowed for the concrete to cure before testing. Where permanent blocking is
not required, the Contractor shall furnish and install temporary blocking and remove it after testing.
Before applying the specified test pressure, the water main shall be slowly filled and air shall be expelled
completely from the pipe, valves and hydrants. If permanent air vents are not located at all high points,
the contractor shall install corporation cocks at such points so that the air can be expelled as the line is
filled with water. After all the air has been expelled, the corporation cocks shall be closed and the test
pressure applied. At the conclusion of the pressure test, the corporation cocks shall be removed and
plugged.
The Contractor shall perform a leakage test concurrently with the pressure test. The pressure test shall
be conducted for a 2-hour period.
The test shall be accomplished by pumping the main up to the required pressure, stopping the pump for
2 hours, and then pumping the main up to the test pressure again. During the test, the section being tested
shall be observed to detect any visible leakage.
A clean container shall be used for holding water for pumping up pressure on the main being tested. This
makeup water shall be sterilized by the addition of chlorine to a concentration of 50 mg/l.
Special Provisions 168
The acceptability of the pressure test and leakage test will be determined by two factors as follows:
1. The loss in pressure shall not exceed 5 psi during the 2-hour test period.
2. The quantity of water lost from the main and appurtenances shall not exceed the number of
gallons during the 2-hour test period as listed in the following table.
Allowable leakage in gallons per 1000 ft. of pipeline* for a 2-hour test period
Nominal Pipe Diameter (inches)
PSI 6" 8" 10" 12" 16" 20" 24"
450 0.95 1.27 1.59 1.91 2.55 3.18 3.82
400 0.90 1.20 1.50 1.80 2.40 3.00 3.60
350 0.84 1.12 1.40 1.69 2.25 2.81 3.37
275 0.75 1.00 1.24 1.49 1.99 2.49 2.99
250 0.71 0.95 1.19 1.42 1.90 2.37 2.85
225 0.68 0.90 1.13 1.35 1.80 2.25 2.70
200 0.64 0.85 1.06 1.28 1.70 2.12 2.55
*If the pipeline under test contains sections of various diameters, the allowable leakage will be the sum
of the computed leakage for each size. For those diameters or pressures not listed, the formula below
shall be used:
The quantity of water lost from the main shall not exceed the number of gallons per hour as determined
by the formula:
𝐿=𝑆𝐷√𝑃
266,400
where:
L = Allowable leakage in gallons/hour
S = Gross length of pipe tested, feet
D = Nominal diameter of the pipe in inches
P = Test pressure during the leakage test in psi
The quantity of water required to restore the pressure shall be accurately determined by either 1) pumping
from an open container of suitable size such that accurate volume measurements can be made by the
Engineer or, 2) by pumping through a positive displacement water meter with a sweep unit hand
registering one (1) gallon per revolution. The meter shall be approved by the Engineer.
Pressure gauges used in the test shall be accompanied with certifications of accuracy from a testing
Laboratory approved by the Engineer.
Any visible leakage detected shall be corrected by the Contractor regardless of the allowable leakage
Special Provisions 169
specified above. Should the tested section fail to meet the pressure test successfully as specified, the
Contractor shall, at no additional expense to the Contracting Agency, locate and repair the defects and
then retest the pipeline. The use of leak detection dye or other substances to detect any visible leakage is
strictly prohibited.
All tests shall be made with the hydrant auxiliary gate valves open and pressure against the hydrant inlet
valve. After the test is completed, each valve shall be tested by closing each in turn and relieving the
pressure beyond. This test of the valve will be acceptable if there is no immediate loss of pressure on the
gauge when the pressure comes against the valve being checked. The Contractor shall verify that the
pressure differential across the valve does not exceed the rated working pressure of the valve.
Prior to calling out the Engineer or Inspector to witness the pressure test, the Contractor shall have all
equipment set up completely ready for operation and shall have successfully performed the test to ensure
that the pipe is in satisfactory condition.
Defective materials or workmanship, discovered as a result of hydrostatic field test, shall be replaced by
the Contractor at no additional expense to the Contracting Agency. Whenever it is necessary to replace
defective material or correct the workmanship, the hydrostatic test shall be re-run at the Contractor’s
expense until a satisfactory test is obtained.

1.CONDITIONS OF USE
1.1.INSTALL ON DISTURBED AREAS THAT REQUIRE IMMEDIATE EROSION PROTECTION.
1.2.USE ON SLOPES REQUIRING STABILIZATION UNTIL PERMANENT VEGETATION CAN BE ESTABLISHED.
1.3.CAN BE USED ALONG THE PERIMETER OF A PROJECT, AS A CHECK DAM IN UNLINED DITCHES AND AROUND TEMPORARY STOCKPILES.
1.4.WATTLES CAN BE STAKED TO THE GROUND USING WILLOW CUTTINGS FOR ADDED REVEGETATION.
1.5.RILLING CAN OCCUR BENEATH AND BETWEEN WATTLES IF NOT PROPERLY ENTRENCHED, ALLOWING WATER TO PASS BELOW AND BETWEEN WATTLES.
2.DESIGN AND INSTALLATION SPECIFICATIONS
2.1.IT IS CRITICAL THAT WATTLES ARE INSTALLED PERPENDICULAR TO THE FLOW DIRECTION AND PARALLEL TO THE SLOPE CONTOUR.
2.2.NARROW TRENCHES SHOULD BE DUG ACROSS THE SLOPE, ON CONTOUR, TO A DEPTH OF 3 TO 5 INCHES ON CLAY SOILS AND SOILS WITH GRADUAL SLOPES.
ON LOOSE SOILS, STEEP SLOPES, AND DURING HIGH RAINFALL EVENTS, THE TRENCHES SHOULD BE DUG TO A DEPTH OF 5 TO 7 INCHES, OR 1/2 TO 2/3 OF THE
THICKNESS OF THE WATTLE.
2.3.START CONSTRUCTION OF TRENCHES AND INSTALLING WATTLES FROM THE BASE OF THE SLOPE AND WORK UPHILL. EXCAVATED MATERIAL SHOULD BE
SPREAD EVENLY ALONG THE UPHILL SLOPE AND COMPACTED USING HAND TAMPING OR OTHER METHOD. CONSTRUCT TRENCHES AT CONTOUR INTERVALS
OF 3 TO 30 FEET APART DEPENDING ON THE STEEPNESS OF THE SLOPE, SOIL TYPE, AND RAINFALL. THE STEEPER THE SLOPE THE CLOSER TOGETHER THE
TRENCHES SHOULD BE CONSTRUCTED. VERTICAL DISTANCE BETWEEN WATTLES IS NOT TO EXCEED 10 FEET.
2.4.INSTALL THE WATTLES SNUGLY INTO THE TRENCHES AND ABUT TIGHTLY END TO END. DO NOT OVERLAP THE ENDS.
2.5.INSTALL STAKES AT EACH END OF THE WATTLE, AND AT 4 FOOT CENTERS ALONG THE ENTIRE LENGTH OF THE WATTLE.
2.6.IF REQUIRED, INSTALL PILOT HOLES FOR THE STAKES USING A STRAIGHT BAR TO DRIVE HOLES THROUGH THE WATTLE AND INTO THE SOIL.
2.7.AT A MINIMUM, WOODEN STAKES SHOULD BE APPROXIMATELY 3/4 X 3/4 X 24 INCHES. WILLOW CUTTINGS OR 3/8-INCH REBAR CAN ALSO BE USED FOR STAKES.
2.8.STAKES SHOULD BE DRIVEN THROUGH THE MIDDLE OF THE WATTLE, LEAVING 2 TO 3 INCHES OF THE STAKE PROTRUDING ABOVE THE WATTLE.
3.MAINTENANCE STANDARDS
3.1.INSPECT WATTLES PRIOR TO FORECASTED RAIN, DAILY DURING EXTENDED RAIN EVENTS, AFTER RAIN EVENTS, WEEKLY DURING THE WET SEASON, AND AT
TWO WEEK INTERVALS AT ALL OTHER TIMES OF THE YEAR.
3.2.REPAIR OR REPLACE SPLIT, TORN, RAVELING, OR SLUMPING WATTLES
3.3.REMOVE SEDIMENT ACCUMULATIONS WHEN EXCEEDING 1/2 THE HEIGHT BETWEEN THE TOP OF THE WATTLE AND THE GROUND SURFACE.
