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.

1-08.5 Time for Completion
Delete this section in its entirety and replace 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:
New Year’s Day
Martin Luther King Day
Memorial Day
Independence July
Labor Day
Veteran’s Day
Thanksgiving Day
the day after Thanksgiving
Christmas Day
Note for holidays that land on a Saturday or Sunday: 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
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 48
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.
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 1 05.11
and 1-05.12.
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 Engineer prior to

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.

enforce any provision of this Contract or to seek redress for any breach thereof, the
Contracting Agency shall be entitled to recover its costs, including reasonable attorney’s
fees, from the Contractor.
1-08.11 Contractor's Plant and Equipment
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 Contracting Agency
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 Contracting Agency of such plant and equipment shall be considered as
extra Work and paid for accordingly.
Neither the Contracting Agency 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 Contracting Agency. 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 Contracting Agency will be provided keys for all fenced, secured
areas.
1-08.12 Attention to Work

1-09 MEASUREMENT AND PAYMENT
1-09.1 Measurement of Quantities
Section 1-09.1 is supplemented with 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.
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

(******)
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
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 53

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
Section 1-09.6 is supplemented as follows:
(******)
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 the Contractor’s total bid. However, the
Contracting Agency does not warrant expressly or by implication that the actual amount of
Work will correspond with those estimates. Payment will be made on the basis of the
amount of Work actually authorized by the Engineer.
1 09.7 Mobilization
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 Contracting Agency.
This item shall also include providing the Engineer and the Inspectors with access to
telephone, facsimile machine, and copy machine during all hours the Contractor is working
on the jobsite; and a table and chair for their use when needed.
Payment will be made for the following bid item(s):
“Mobilization & Demobilization,” Lump Sum.
1-09.9 Payments
Section 1-09.9 is revised supplemented as follows:
(******)
Delete the fourth paragraph and replace it with the following:
(******)
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 meeting.
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
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 54
Work are tentative, and made only for the purpose of determining progress payment. 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 – the estimated percentage complete multiplied
by the Bid Forms amount for each lump sum item, or per the schedule of values for
that item.
3. Materials on Hand – 100 percent of invoiced cost of material delivered to job site or
other storage area approved by the Engineer.
4. Change Orders – entitlement for approved extra cost or completed extra Work as
determined by the Engineer.
Progress payments will be made in accordance with the progress estimate less:
1. Retainage per Section 1-09.9(1);
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.
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.
Section 1-09.9 is supplemented as follows:
(******)
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
Section 1-09.9(1) is supplemented as follows:
(******)
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 55
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 Contracting
Agency has no unsatisfied claims against the Contractor. In the event claims are filed, the
Contracting Agency shall withhold, until such claims are satisfied, a sum sufficient to
satisfy all claims and to pay attorney's fees. In addition, the Contracting Agency shall
withhold such amount as is required to satisfy any claims by the Contracting Agency
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 Contracting Agency 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 Contracting Agency against the lien. If
any lien remains unsatisfied after all payments are made, the Contractor shall reimburse
to the Contracting Agency 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
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).
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,
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 56
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:

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.
1-09.9(3) Final Payment
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.
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 57
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).

located. The decision of the arbitrator and the specific basis for the decision shall be in
writing. The arbitrator shall use the Contract as a basis for decisions.

Washington. The grounds for the petition for review are limited to showing that the
findings and decision:
1. Are not responsive to the questions submitted;
2. Is contrary to the terms of the contract or any component thereof;
3. Is arbitrary and/or is not based upon the applicable facts and the law controlling the
issues submitted to arbitration. The board of arbitrators shall support its decision
by setting forth in writing their findings and conclusions based on the evidence
adduced at any such hearing.
The arbitration shall be conducted in accordance with the statutes of the State of
Washington and court decisions governing such procedure.

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 minimum of
92 percent of the maximum density. The maximum density shall be determined by WSDOT FOP
for AASHTO T 729. The specified level of density attained will be determined by the evaluation of
the density of the pavement. The density of the pavement shall be determined in accordance with
WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of the
Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using cores to
determine density.
Tests for the determination of the pavement density will be taken in accordance with the required
procedures for measurement by a nuclear density gauge or roadway cores after completion of the
finish rolling.
If the Contracting Agency uses a nuclear density gauge to determine density the test procedures
FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the mix is placed and
prior to opening to traffic.
Roadway cores for density may be obtained by either the Contracting Agency or the Contractor in
accordance with WSDOT SOP 734. The core diameter shall be 4-inches minimum, unless
otherwise approved by the Engineer. Roadway cores will be tested by the Contracting Agency in
accordance with WSDOT FOP for AASHTO T 166.

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.

Compaction shall take place when the mixture is in the proper condition so that no undue
displacement, cracking, or shoving occurs. Areas inaccessible to large compaction equipment
shall be compacted by other mechanical means. Any HMA that becomes loose, broken,
contaminated, shows an excess or deficiency of asphalt, or is in any way defective, shall be
removed and replaced with new hot mix that shall be immediately compacted to conform to the
surrounding area.
The type of rollers to be used and their relative position in the compaction sequence shall
generally be the Contractor’s option, provided the specified densities are attained. Unless the
Engineer has approved otherwise, rollers shall only be operated in the static mode when the
internal temperature of the mix is less than 175°F. Regardless of mix temperature, a roller shall
not be operated in a mode that results in checking or cracking of the mat. Rollers shall only be

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

CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 7-17
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.
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.

*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 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.
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 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
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021

7-21.3 Construction Requirements
7-21.3(1) Preparation
The Contractor shall make all necessary provisions to ensure service conditions and structural
conditions of host pipe are suitable for installation and warranty of the liner. The Contractor shall
verify the lengths in the field prior to ordering and prior to impregnation of the tube with resin, to
ensure that the tube will have sufficient length to extend the entire length of the run. The
Contractor shall also measure the inside diameter of the existing pipelines in the field prior to
ordering liner so that the liner can be installed in a tight-fitted condition.
7-21.3(1)A Flow Management
It shall be the Contractor's responsibility to maintain operation of the existing sewer systems
throughout the duration of the project without any interruption of sewer service. The Contractor
shall divert all flows around each segment of the pipe designated for rehabilitation. This diversion
shall consist of redirecting flow from an upstream manhole and discharging it to a manhole
downstream of the rehabilitation operation. This can be accomplished via a combination of
pumping and/or gravity flow. After the work is completed, flow shall be returned to the
rehabilitated sewer system. The area affected by the bypass operation shall be fully restored.
Bypass pumping shall be scheduled for continuous operation. Back-up equipment shall be on-
site and available for periods of maintenance, refueling or failure of the primary bypass pump(s)
or diversion system. Bypass pumping shall be done in such a manner as not to damage private
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 7-37
or public property, or create a nuisance or public menace. The bypass-pumping pipe shall not
block any driveways or intersections unless approved by the Engineer. The sewage shall be
pumped through a watertight hose or pipe that is adequately protected from traffic. The discharge
of raw sewage to private property, city streets, sidewalks, storm sewer, or any location other than
an approved sanitary sewer is prohibited. The Contractor shall be liable for all cleanup, damages,
and resultant fines should the Contractor's operation cause any backups or overflows.
The Contractor's bypass operation shall be sized to handle, at a minimum, the full pipe capacity in
each subject line removed from service. If flow conditions are greater than full pipe, the
Contractor may elect to wait for flow conditions to subside prior to removing the subject line from
service. Working days will not be charged for the period of time during which the flow is greater
than full pipe. No additional payment will be made for periods of high flows during which the
Contractor elects to wait for lower flows. Once the Contractor removes a section of line from
service he/she is responsible to bypass any and all flow in the system during construction, even in
the event the system surcharges and exceeds the full pipe capacity, until the line is returned to
service.
All bypassing systems shall be approved by the Engineer. A plan for bypassing the existing
sewer system shall be submitted by the Contractor for review. The Contractor's plan for bypass
pumping shall be satisfactory to the Owner before the Contractor will be allowed to commence
bypass pumping. The sewage bypass pumping plan shall include an emergency response plan
to be followed in the event of a failure of the bypass pumping. The review of the bypassing
system and equipment by the Engineer shall in no way relieve the Contractor of his responsibility
and public liability.
The Contractor shall coordinate activities with impacted property owners. Property Owners shall
be notified that their side sewer will be out of service for a specified period of time, as approved
by the Engineer.
When there exist situations where impacted properties cannot be disconnected, plugged, or
subjected to any other service interruption, i.e., hospitals, care facilities, restaurants, etc., bypass
pumping of the side sewer to the downstream sanitary sewer system shall be required prior to
insertion of the liner system. The Contractor shall verify whether a property is able to be
interrupted prior to lining operations. If the subject property’s side sewer requires bypass
pumping, the costs for the bypass pumping shall be covered by Force Account.
7-21.3(1)B Cleaning
Clean and prepare pipe per CIPP Manufacturer’s or Assembler’s requirements.
7-21.3(1)C Point Repairs

holes in the pipeline as follows:
CITY OF RENTON LIFT STATION AND FORCE MAIN REHABILITATION PHASE 2 (GROUP 1B) WINTER 2021
SPECIAL PROVISIONS 7-38
1. Grout all defects as recommended by liner manufacturer or installer.
2. Grout all locations with active infiltration.
The determination of an excessive leak shall be made by the Owner’s representative and shall be
based on PACP leak designations. Leaks that would be categorized as a Runner(IR) – Severity 4
or Gusher(IG) – Severity 5 shall be considered as excessive. Leaks categorized as Weeper(IW)
– Severity 2 or Dripper(ID) – Severity 3 shall be considered incidental to the unit price for CIPP
rehabilitation.
Make point repairs of any host pipe defect that can be removed by conventional sewer cleaning
equipment or by remotely performed repair methods acceptable to the Engineer.
Remove protruding laterals, rolled gaskets, roots, mineral deposits, and other objects protruding
into the host pipe, internally with a remote controlled cutter.
Pipelines that cannot be rehabilitated due to excessive leakage may be deleted from the project
at the Engineers discretion.
7-21.3(1)D Manholes
Protect all manholes to withstand forces generated by the equipment while installing the liner.
7-21.3(2) Liner Installation
7-21.3(2)A Inversion Method
The impregnated tube shall be inserted through an existing manhole or other access point by
means of the Manufacturer’s or Assembler’s recommended installation process. The application
of a hydrostatic head, compressed air, or other means shall fully extend the liner to the next
designated manhole or termination point and inflate and firmly adhere the liner to the pipe wall.
The liner shall be installed at a rate less than 10 feet per minute at all times.
Liner shall not be installed through intermediate manholes unless specifically requested in
advance in writing and approved by the Engineer.
Liner installation shall be in accordance with ASTM F 1216, Section 7.
When inversion is by hydrostatic head, the Contractor shall use methods that control the
installation rate, accounting for the increase in hydrostatic head in pipes that have significant
elevation change.
7-21.3(2)B Pull/Winch Method
The impregnated tube shall be pulled into place within the host pipe with the aid of a power winch
that is equipped with a device to monitor the force and prevent excessive tension and tube

allowed to reach ambient temperature before coating. If condensation is present, dry
thoroughly prior to coating.
2. Ferrous Metals
a. SSPC-SP10 Near white blast cleaning
3. Ductile and Cast-Iron Materials
a. It is strongly recommended that ductile iron and cast-iron pipe or materials to be
field coated should be purchased factory primed without the standard asphalt
coating. Field removal of asphalt coatings is extremely difficult and overly
aggressive preparation can create a damaged surface unsuitable for coating.
b. Remove all oils, grease, and other contaminants using solvent cleaning prior to
abrasive blasting or power tool cleaning. Blemishes or staining on the prepared
surface are acceptable if such items cannot be removed by light scraping with a
knife. SSPC-SP10 blue-gray with surface profile of 2.0 Mil, minimum. Do not
burnish the surface. Clean all surfaces of dust and loose residue immediately prior
to coating. See NAPF 500-03-04/05.
4. Bolts must be masked with painter’s tape or similar prior to the application of coating
system. Do not apply coating on the bolts. Remove painter’s tape once coating system
has dried to the touch.

11.15 Temporary Sewage Pumping During Coating Removal at
Devil’s Elbow Lift Station
Part 1 – General
Summary
During the wet well coating removal process at Devil’s Elbow Lift Station, the sewage within
the wet well needs to be emptied. Below is the description of one alternative to remove the
existing sewage in the wet well and re-route the incoming sewage around the lift station
temporarily. Contractor may submit other alternatives for review and approval. All work
described below must be coordinated closely with the City crew. It is the City’s intention to
keep the functionality of the lift station in operation while performing the coating removal
activity.
The Devil’s Elbow Lift Station consists of a wet well and a valve vault that houses the meter
and check valve. This proposed Lift Station and Force Main Rehabilitation Phase 2 project
includes work to install a pigging port in the Devil’s Elbow mechanical vault, downstream of
the existing check valves. If installation of this pigging port is completed before coating
removal work commences, a temporary sewer conveyance and pumping system can divert
incoming sewage from entering the wet well and into the just-installed pigging port.
This can be accomplished by: plugging the incoming gravity sewer into the wet well and
installing a temporary pump from the first gravity sewer manhole upstream from the Devil’s
Elbow Lift Station, located less than 20-feet southeast of the wet well. The discharge of this
temporary pump can be routed across the ground surface to the mechanical vault and
connected securely to the pigging port assembly. Once this alternative sewage conveyance is
in place, the wet well can be emptied and prepared for coating removal. Coordinate with City
on temporary pump location and piping to minimize interruption to trail use.
Submittals
The Contractor shall submit the construction sequencing on how they plan to drain the force
main for the access port installation electronically if the Contractor is using another approach.
The submittal shall contain but not be limited to the following:
• Step by step description on how to re-route inflow sewage to bypass the wet well, including
how to empty the wet well and prepare the wet well for coating removal.
• All equipment that will be needed for this operation (including but not limited to backup
pump, sewage level monitoring and telemetry, vactor truck, and other equipment).
• Equipment staging area.
• Anticipated downtime of the lift station.
