As evidence that the Bidder meets the Supplemental Criteria stated above, the 20
apparent low Bidder must submit to the Contracting Agency by 12:00 P.M. (noon) of the 21
second business day following the bid submittal deadline, a written statement verifying 22
that the Bidder meets the supplemental criteria together with supporting documentation 23
(sufficient in the sole judgment of the Contracting Agency) demonstrating compliance 24
with the Supplemental Criteria. The Contracting Agency reserves the right to request 25
further documentation as needed from the low Bidder and documentation from other 26
Bidders as well to assess Bidder responsibility and compliance with all bidder 27
responsibility criteria. The Contracting Agency also reserves the right to obtain 28
information from third-parties and independent sources of information concerning a 29
Bidder’s compliance with the mandatory and supplemental criteria, and to use that 30
information in their evaluation. The Contracting Agency may consider mitigating 31
factors in determining whether the Bidder complies with the requirements of the 32
supplemental criteria. 33
34
The basis for evaluation of Bidder compliance with these mandatory and supplemental 35
criteria shall include any documents or facts obtained by Contracting Agency (whether 36
from the Bidder or third parties) including but not limited to: (i) financial, historical, or 37
operational data from the Bidder; (ii) information obtained directly by the Contracting 38
Agency from others for whom the Bidder has worked, or other public agencies or 39
private enterprises; and (iii) any additional information obtained by the Contracting 40
Agency which is believed to be relevant to the matter. 41

If the Contracting Agency determines the Bidder does not meet the bidder 1
responsibility criteria above and is therefore not a responsible Bidder, the Contracting 2
Agency shall notify the Bidder in writing, with the reasons for its determination. If the 3
Bidder disagrees with this determination, it may appeal the determination within two (2) 4
business days of the Contracting Agency’s determination by presenting its appeal and 5
any additional information to the Contracting Agency. The Contracting Agency will 6
consider the appeal and any additional information before issuing its final 7
determination. If the final determination affirms that the Bidder is not responsible, the 8
Contracting Agency will not execute a contract with any other Bidder until at least two 9
business days after the Bidder determined to be not responsible has received the 10
Contracting Agency’s final determination. 11

modify the criteria. Such requests shall be in writing, describe the nature of the 16
concerns, and propose specific modifications to the criteria. Bidders shall submit such 17
requests to the Contracting Agency no later than five (5) business days prior to the bid 18
submittal deadline and address the request to the Project Engineer or such other 19
person designated by the Contracting Agency in the Bid Documents. 20

After opening and reading proposals, the Contracting Agency will check them for 8
correctness of extensions of the prices per unit and the total price. If a discrepancy exists 9
between the price per unit and the extended amount of any bid item, the price per unit 10
will control. If a minimum bid amount has been established for any item and the bidder’s 11
unit or lump sum price is less than the minimum specified amount, the Contracting 12
Agency will unilaterally revise the unit or lump sum price, to the minimum specified 13
amount and recalculate the extension. The total of extensions, corrected where 14
necessary, including sales taxes where applicable and such additives and/or alternates 15
as selected by the Contracting Agency, will be used by the Contracting Agency for award 16
purposes and to fix the Awarded Contract Price amount and the amount of the contract 17

highest percentage of recycled materials in the Project, per the form submitted with the 27
Bid Proposal. If those percentages are also exactly equal, then the tie-breaker will be 28
determined by drawing as follows: Two or more slips of paper will be marked as follows: 29
one marked “Winner” and the other(s) marked “unsuccessful”. The slips will be folded to 30
make the marking unseen. The slips will be placed inside a box. One authorized 31
representative of each Bidder shall draw a slip from the box. Bidders shall draw in 32
alphabetic order by the name of the firm as registered with the Washington State 33
Department of Licensing. The slips shall be unfolded and the firm with the slip marked 34
“Winner” will be determined to be the successful Bidder and eligible for Award of the 35
Contract. Only those Bidders who submitted a Bid total that is exactly equal to the lowest 36
responsive Bid, and with a proposed recycled materials percentage that is exactly equal 37
to the highest proposed recycled materials amount, are eligible to draw. 38

Supplement this section with the following: 6
7
If the Contractor fails to remedy defective or unauthorized work within the time specified 8
in a written notice from the Engineer, or fails to perform any part of the work required by 9
the Contract Documents, the Engineer may correct and remedy such work as may be 10
identified in the written notice, with Contracting Agency forces or by such other means as 11
the Contracting Agency may deem necessary. 12
13
If the Contractor fails to comply with a written order to remedy what the Engineer 14
determines to be an emergency situation, the Engineer may have the defective and 15
unauthorized work corrected immediately, have the rejected work removed and replaced, 16
or have work the Contractor refuses to perform completed by using Contracting Agency 17
or other forces. An emergency situation is any situation when, in the opinion of the 18
Engineer, a delay in its remedy could be potentially unsafe, or might cause serious risk 19
of loss or damage to the public. 20
21
Direct or indirect costs incurred by the Contracting Agency attributable to correcting and 22
remedying defective or unauthorized work, or work the Contractor failed or refused to 23
perform, shall be paid by the Contractor. Payment will be deducted by the Engineer from 24
monies due, or to become due, the Contractor. Such direct and indirect costs shall 25
include in particular, but without limitation, compensation for additional professional 26
services required, and costs for repair and replacement of work of others destroyed or 27
damaged by correction, removal, or replacement of the Contractor’s unauthorized work. 28
29
No adjustment in contract time or compensation will be allowed because of the delay in 30
the performance of the work attributable to the exercise of the Contracting Agency’s 31
rights provided by this Section. 32
33
The rights exercised under the provisions of this section shall not diminish the 34
Contracting Agency’s right to pursue any other avenue for additional remedy or damages 35
with respect to the Contractor’s failure to perform the work as required. 36

1-05.11(1) Substantial Completion Date 7
When the Contractor considers the work to be substantially complete, the Contractor 8
shall so notify the Engineer and request the Engineer establish the Substantial 9
Completion Date. The Contractor’s request shall list the specific items of work that 10
remain to be completed in order to reach physical completion. The Engineer will 11
schedule an inspection of the work with the Contractor to determine the status of 12
completion. The Engineer may also establish the Substantial Completion Date 13
unilaterally. 14
15
If, after this inspection, the Engineer concurs with the Contractor that the work is 16
substantially complete and ready for its intended use, the Engineer, by written notice to 17
the Contractor, will set the Substantial Completion Date. If, after this inspection the 18
Engineer does not consider the work substantially complete and ready for its intended 19
use, the Engineer will, by written notice, so notify the Contractor giving the reasons 20
therefor. 21
22
Upon receipt of written notice concurring in or denying substantial completion, whichever 23
is applicable, the Contractor shall pursue vigorously, diligently and without unauthorized 24
interruption, the work necessary to reach Substantial and Physical Completion. The 25
Contractor shall provide the Engineer with a revised schedule indicating when the 26
Contractor expects to reach substantial and physical completion of the work. 27

The above process shall be repeated until the Engineer establishes the Substantial 29
Completion Date and the Contractor considers the work physically complete and ready for 30
final inspection. 31
32
1-05.11(2) Final Inspection and Physical Completion Date 33
When the Contractor considers the work physically complete and ready for final 34
inspection, the Contractor by written notice, shall request the Engineer to schedule a 35
final inspection. The Engineer will set a date for final inspection. The Engineer and the 36
Contractor will then make a final inspection and the Engineer will notify the Contractor in 37
writing of all particulars in which the final inspection reveals the work incomplete or 38
unacceptable. The Contractor shall immediately take such corrective measures as are 39
necessary to remedy the listed deficiencies. Corrective work shall be pursued vigorously, 40
diligently, and without interruption until physical completion of the listed deficiencies. This 41
process will continue until the Engineer is satisfied the listed deficiencies have been 42
corrected. 43
44
If action to correct the listed deficiencies is not initiated within 7 days after receipt of the 45
written notice listing the deficiencies, the Engineer may, upon written notice to the 46
Contractor, take whatever steps are necessary to correct those deficiencies pursuant to 47
Section 1-05.7. 48
The Contractor will not be allowed an extension of contract time because of a delay in 49
the performance of the work attributable to the exercise of the Engineer’s right 50
hereunder. 51
2022–23 TRAFFIC CALMING – LAKE WASHINGTON BOULEVARD N
May 2023 SP-19
Upon correction of all deficiencies, the Engineer will notify the Contractor and the 1
Contracting Agency, in writing, of the date upon which the work was considered 2
physically complete. That date shall constitute the Physical Completion Date of the 3
contract, but shall not imply acceptance of the work or that all the obligations of the 4
Contractor under the contract have been fulfilled. 5

1-05.11(3) Operational Testing 7
It is the intent of the Contracting Agency to have at the Physical Completion Date a 8
complete and operable system. Therefore when the work involves the installation of 9
machinery or other mechanical equipment; street lighting, electrical distribution or signal 10
systems; irrigation systems; buildings; or other similar work it may be desirable for the 11
Engineer to have the Contractor operate and test the work for a period of time after final 12
inspection but prior to the physical completion date. Whenever items of work are listed in 13
the Contract Provisions for operational testing they shall be fully tested under operating 14
conditions for the time period specified to ensure their acceptability prior to the Physical 15
Completion Date. During and following the test period, the Contractor shall correct any 16
items of workmanship, materials, or equipment which prove faulty, or that are not in first 17
class operating condition. Equipment, electrical controls, meters, or other devices and 18
equipment to be tested during this period shall be tested under the observation of the 19
Engineer, so that the Engineer may determine their suitability for the purpose for which 20
they were installed. The Physical Completion Date cannot be established until testing 21
and corrections have been completed to the satisfaction of the Engineer. 22
23
The costs for power, gas, labor, material, supplies, and everything else needed to 24
successfully complete operational testing, shall be included in the unit contract prices 25
related to the system being tested, unless specifically set forth otherwise in the proposal. 26
27
Operational and test periods, when required by the Engineer, shall not affect a 28
manufacturer’s guaranties or warranties furnished under the terms of the contract. 29

The Washington State Department of Revenue has issued special rules on the State 25
sales tax. Sections 1-07.2(1) through 1-07.2(3) are meant to clarify those rules. The 26
Contractor should contact the Washington State Department of Revenue for answers to 27
questions in this area. The Contracting Agency will not adjust its payment if the 28
Contractor bases a bid on a misunderstood tax liability. 29
The Contractor shall include all Contractor-paid taxes in the unit bid prices or other 30
contract amounts. In some cases, however, state retail sales tax will not be included. 31
Section 1-07.2(2) describes this exception. 32
33
The Contracting Agency will pay the retained percentage (or release the Contract Bond if 34
a FHWA-funded Project) only if the Contractor has obtained from the Washington State 35
Department of Revenue a certificate showing that all contract-related taxes have been 36
paid (RCW 60.28.051). The Contracting Agency may deduct from its payments to the 37
Contractor any amount the Contractor may owe the Washington State Department of 38
Revenue, whether the amount owed relates to this contract or not. Any amount so 39
deducted will be paid into the proper State fund. 40
41
1-07.2(1) State Sales Tax — Rule 171 42
WAC 458-20-171, and its related rules, apply to building, repairing, or improving streets, 43
roads, etc., which are owned by a municipal corporation, or political subdivision of the 44
state, or by the United States, and which are used primarily for foot or vehicular traffic. 45
This includes storm or combined sewer systems within and included as a part of the 46
street or road drainage system and power lines when such are part of the roadway 47
lighting system. For work performed in such cases, the Contractor shall include 48

terminate the Contract or, at its discretion, procure or renew such insurance and pay any 4
and all premiums in connection therewith, with any sums so expended to be repaid to the 5

Each working day shall be charged to the contract as it occurs, until the contract work is 20
physically complete. If substantial completion has been granted and all the authorized 21
working days have been used, charging of working days will cease. Each week the 22
Engineer will provide the Contractor a statement that shows the number of working days: 23
(1) charged to the contract the week before; (2) specified for the physical completion of 24
the contract; and (3) remaining for the physical completion of the contract. The statement 25
will also show the nonworking days and all partial or whole days the Engineer declares 26

The Contracting Agency has estimated and included in the Proposal, dollar amounts for 34
all items to be paid per force account, only to provide a common proposal for Bidders. All 35
such dollar amounts are to become a part of Contractor's total bid. However, the 36
Contracting Agency does not warrant expressly or by implication, that the actual amount 37
of work will correspond with those estimates. Payment will be made on the basis of the 38
amount of work actually authorized by the Engineer. 39
40
1-09.8 Payment For Material On Hand 41
The last paragraph of Section 1-09.8 is revised to read: 42
43
(August 3, 2009 WSDOT GSP, Option 1) 44
The Contracting Agency will not pay for material on hand when the invoice cost is less than 45
$2,000. As materials are used in the work, credits equaling the partial payments for them 46
will be taken on future estimates. Each month, no later than the estimate due date, the 47
Contractor shall submit a letter to the Engineer that clearly states: 1) the amount originally 48
paid on the invoice (or other record of production cost) for the items on hand, 2) the dollar 49
amount of the material incorporated into each of the various work items for the month, and 3) 50
the amount that should be retained in material on hand items. If work is performed on the 51
items and the Contractor does not submit a letter, all of the previous material on hand 52
2022–23 TRAFFIC CALMING – LAKE WASHINGTON BOULEVARD N
May 2023 SP-35
payment will be deducted on the estimate. Partial payment for materials on hand shall not 1
constitute acceptance. Any material will be rejected if found to be faulty even if partial 2
payment for it has been made. 3

1-09.9 Payments 5
(December 30, 2022 APWA GSP) 6
7
Section 1-09.9 is revised to read: 8
9
The basis of payment will be the actual quantities of Work performed according to the 10
Contract and as specified for payment. 11
12
The Contractor shall submit a breakdown of the cost of lump sum bid items at the 13
Preconstruction Conference, to enable the Project Engineer to determine the Work 14
performed on a monthly basis. A breakdown is not required for lump sum items that 15
include a basis for incremental payments as part of the respective Specification. Absent 16
a lump sum breakdown, the Project Engineer will make a determination based on 17
information available. The Project Engineer’s determination of the cost of work shall be 18
final. 19
20
Progress payments for completed work and material on hand will be based upon 21
progress estimates prepared by the Engineer. A progress estimate cutoff date will be 22
established at the preconstruction conference. 23
24
The initial progress estimate will be made not later than 30 days after the Contractor 25
commences the work, and successive progress estimates will be made every month 26
thereafter until the Completion Date. Progress estimates made during progress of the 27
work are tentative, and made only for the purpose of determining progress payments. 28
The progress estimates are subject to change at any time prior to the calculation of the 29
final payment. 30
31
The value of the progress estimate will be the sum of the following: 32
1. Unit Price Items in the Bid Form — the approximate quantity of acceptable units of 33
work completed multiplied by the unit price. 34
2. Lump Sum Items in the Bid Form — based on the approved Contractor’s lump sum 35
breakdown for that item, or absent such a breakdown, based on the Engineer’s 36
determination. 37
3. Materials on Hand — 100 percent of invoiced cost of material delivered to Job site 38
or other storage area approved by the Engineer. 39
4. Change Orders — entitlement for approved extra cost or completed extra work as 40
determined by the Engineer. 41
42
Progress payments will be made in accordance with the progress estimate less: 43
1. Retainage per Section 1-09.9(1), on non FHWA-funded projects; 44
2. The amount of progress payments previously made; and 45
3. Funds withheld by the Contracting Agency for disbursement in accordance with the 46
Contract Documents. 47
48
Progress payments for work performed shall not be evidence of acceptable performance 49
or an admission by the Contracting Agency that any work has been satisfactorily 50
completed. The determination of payments under the contract will be final in accordance 51
with Section 1-05.1. 52
53
2022–23 TRAFFIC CALMING – LAKE WASHINGTON BOULEVARD N
May 2023 SP-36
Failure to perform obligations under the Contract by the Contractor may be decreed by the 1
Contracting Agency to be adequate reason for withholding any payments until compliance 2
is achieved. 3
4
Upon completion of all Work and after final inspection (Section 1-05.11), the amount due 5
the Contractor under the Contract will be paid based upon the final estimate made by the 6
Engineer and presentation of a Final Contract Voucher Certification to be signed by the 7
Contractor. The Contractor's signature on such voucher shall be deemed a release of all 8
claims of the Contractor unless a Certified Claim is filed in accordance with the 9
requirements of Section 1-09.11 and is expressly excepted from the Contractor’s 10
certification on the Final Contract Voucher Certification. The date the Contracting Agency 11
signs the Final Contract Voucher Certification constitutes the final acceptance date 12
(Section 1-05.12). 13
14
If the Contractor fails, refuses, or is unable to sign and return the Final Contract Voucher 15
Certification or any other documentation required for completion and final acceptance of 16
the Contract, the Contracting Agency reserves the right to establish a Completion Date 17
(for the purpose of meeting the requirements of RCW 60.28) and unilaterally accept the 18
Contract. Unilateral final acceptance will occur only after the Contractor has been 19
provided the opportunity, by written request from the Engineer, to voluntarily submit such 20
documents. If voluntary compliance is not achieved, formal notification of the impending 21
establishment of a Completion Date and unilateral final acceptance will be provided by 22
email with delivery confirmation from the Contracting Agency to the Contractor, which will 23
provide 30 calendar days for the Contractor to submit the necessary documents. The 30 24
calendar day period will begin on the date the email with delivery confirmation is received 25
by the Contractor. The date the Contracting Agency unilaterally signs the Final Contract 26
Voucher Certification shall constitute the Completion Date and the final acceptance date 27
(Section 1-05.12). The reservation by the Contracting Agency to unilaterally accept the 28
Contract will apply to Contracts that are Physically Completed in accordance with 29
Section 1-08.5, or for Contracts that are terminated in accordance with Section 1-08.10. 30
Unilateral final acceptance of the Contract by the Contracting Agency does not in any 31
way relieve the Contractor of their responsibility to comply with all Federal, State, tribal, 32
or local laws, ordinances, and regulations that affect the Work under the Contract. 33
34
Payment to the Contractor of partial estimates, final estimates, and retained percentages 35
shall be subject to controlling laws. 36

require the use of small steel wheel rollers, plate compactors, or pneumatic rollers to 24
avoid bridging across preleveled areas by the compaction equipment. Equipment used 25
for the compaction of preleveling HMA shall be approved by the Engineer. 26
27
Before construction of HMA on an existing paved surface, the entire surface of the 28
pavement shall be clean. All fatty asphalt patches, grease drippings, and other 29
objectionable matter shall be entirely removed from the existing pavement. All 30
pavements or bituminous surfaces shall be thoroughly cleaned of dust, soil, pavement 31
grindings, and other foreign matter. All holes and small depressions shall be filled with an 32
appropriate class of HMA. The surface of the patched area shall be leveled and 33
compacted thoroughly. Prior to the application of tack coat, or paving, the condition of 34
the surface shall be approved by the Engineer. 35
36
A tack coat of asphalt shall be applied to all paved surfaces on which any course of HMA 37
is to be placed or abutted; except that tack coat may be omitted from clean, newly paved 38
surfaces at the discretion of the Engineer. Tack coat shall be uniformly applied to cover 39
the existing pavement with a thin film of residual asphalt free of streaks and bare spots at 40
a rate between 0.02 and 0.10 gallons per square yard of retained asphalt. The rate of 41
application shall be approved by the Engineer. A heavy application of tack coat shall be 42
applied to all joints. For Roadways open to traffic, the application of tack coat shall be 43
limited to surfaces that will be paved during the same working shift. The spreading 44
equipment shall be equipped with a thermometer to indicate the temperature of the tack 45
coat material. 46

After the required amount of mineral materials, asphalt binder, recycling agent and anti-26
stripping additives have been introduced into the mixer the HMA shall be mixed until 27
complete and uniform coating of the particles and thorough distribution of the asphalt 28
binder throughout the mineral materials is ensured. 29
30
When discharged, the temperature of the HMA shall not exceed the optimum mixing 31
temperature by more than 25°F as shown on the reference mix design report or as 32
approved by the Engineer. Also, when a WMA additive is included in the manufacture of 33
HMA, the discharge temperature of the HMA shall not exceed the maximum 34
recommended by the manufacturer of the WMA additive. A maximum water content of 2 35
percent in the mix, at discharge, will be allowed providing the water causes no problems 36
with handling, stripping, or flushing. If the water in the HMA causes any of these 37
problems, the moisture content shall be reduced as directed by the Engineer. 38
39
Storing or holding of the HMA in approved storage facilities will be permitted with 40
approval of the Engineer, but in no event shall the HMA be held for more than 24 hours. 41
HMA held for more than 24 hours after mixing shall be rejected. Rejected HMA shall be 42
disposed of by the Contractor at no expense to the Contracting Agency. The storage 43
facility shall have an accessible device located at the top of the cone or about the third 44
point. The device shall indicate the amount of material in storage. No HMA shall be 45
accepted from the storage facility when the HMA in storage is below the top of the cone 46
of the storage facility, except as the storage facility is being emptied at the end of the 47
working shift. 48
49
Recycled asphalt pavement (RAP) utilized in the production of HMA shall be sized prior 50
to entering the mixer so that a uniform and thoroughly mixed HMA is produced. If there is 51
evidence of the recycled asphalt pavement not breaking down during the heating and 52

5-04.3(7) Spreading and Finishing 8
The mixture shall be laid upon an approved surface, spread, and struck off to the grade 9
and elevation established. HMA pavers complying with Section 5-04.3(3) shall be used 10
to distribute the mixture. Unless otherwise directed by the Engineer, the nominal 11
compacted depth of any layer of any course shall not exceed the following: 12
13
HMA Class 1” 0.35 feet 14
HMA Class ¾” and HMA Class ½” 15
wearing course 0.30 feet 16
other courses 0.35 feet 17
HMA Class ⅜” 0.15 feet 18
19
On areas where irregularities or unavoidable obstacles make the use of mechanical 20
spreading and finishing equipment impractical, the paving may be done with other 21
equipment or by hand. 22
23
When more than one JMF is being utilized to produce HMA, the material produced for 24
each JMF shall be placed by separate spreading and compacting equipment. The 25
intermingling of HMA produced from more than one JMF is prohibited. Each strip of HMA 26
placed during a work shift shall conform to a single JMF established for the class of HMA 27
specified unless there is a need to make an adjustment in the JMF. 28

5-04.3 (9)D Mixture Acceptance – Commercial Evaluation 1
If sampled and tested, HMA produced under Commercial Evaluation and having all 2
constituents falling within the tolerance limits of the job mix formula shall be accepted at 3
the unit Contract price with no further evaluation. When one or more constituents fall 4
outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the 5
lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate 6
CPF. The commercial tolerance limits will be used in the calculation of the CPF and the 7
maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the 8
existing sublots or samples from the street shall be tested to provide a minimum of three 9
sets of results for evaluation. 10
11
For each lot of HMA mix produced and tested under Commercial Evaluation when the 12
calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be 13
determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 14
60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product 15
of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of 16
mix. 17
18
If a constituent is not measured in accordance with these Specifications, its individual 19
pay factor will be considered 1.00 in calculating the CPF. 20
21
5-04.3(10) HMA Compaction Acceptance 22
HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 23
lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a 24
specified compacted course thickness greater than 0.10-foot, shall be compacted to a 25
specified level of relative density. The specified level of relative density shall be a CPF of 26
not less than 0.75 when evaluated in accordance with Section 1-06.2, using a LSL of 27
92.0 (minimum of 92 percent of the maximum density). The maximum density shall be 28
determined by WSDOT FOP for AASHTO T 729. The specified level of density attained 29
will be determined by the evaluation of the density of the pavement. The density of the 30
pavement shall be determined in accordance with WSDOT FOP for WAQTC TM 8, 31
except that gauge correlation will be at the discretion of the Engineer, when using the 32
nuclear density gauge and WSDOT SOP 736 when using cores to determine density. 33
34
Tests for the determination of the pavement density will be taken in accordance with the 35
required procedures for measurement by a nuclear density gauge or Roadway cores 36
after completion of the finish rolling. 37
38
If the Contracting Agency uses a nuclear density gauge to determine density the test 39
procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the 40
mix is placed and prior to opening to traffic. 41
42
Roadway cores for density may be obtained by either the Contracting Agency or the 43
Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches 44
minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by 45
the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. 46
47
If the Contract includes the Bid item “Roadway Core”, the cores shall be obtained by the 48
Contractor in the presence of the Engineer on the same day the mix is placed and at 49
locations designated by the Engineer. If the Contract does not include the Bid item 50
“Roadway Core”, the Contracting Agency will obtain the cores. 51
52
2022–23 TRAFFIC CALMING – LAKE WASHINGTON BOULEVARD N
May 2023 SP-49
For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s 1
request after the Engineer is satisfied that material conforming to the Specifications can 2
be produced. 3
4
HMA mixture accepted by commercial evaluation and HMA constructed under conditions 5
other than those listed above shall be compacted on the basis of a test point evaluation 6
of the compaction train. The test point evaluation shall be performed in accordance with 7
instructions from the Engineer. The number of passes with an approved compaction 8
train, required to attain the maximum test point density, shall be used on all subsequent 9
paving. 10
11
HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling 12
wheel rutting shall be compacted with a pneumatic tire roller unless otherwise approved 13
by the Engineer. 14
15
Test Results 16
For a sublot that has been tested with a nuclear density gauge that did not meet the 17
minimum of 92 percent of the reference maximum density in a compaction lot with a CPF 18
below 1.00 and thus subject to a price reduction or rejection, the Contractor may request 19
that a core be used for determination of the relative density of the sublot. The relative 20
density of the core will replace the relative density determined by the nuclear density 21
gauge for the sublot and will be used for calculation of the CPF and acceptance of HMA 22
compaction lot. 23
24
When cores are taken by the Contracting Agency at the request of the Contractor, they 25
shall be requested by noon of the next workday after the test results for the sublot have 26
been provided or made available to the Contractor. Core locations shall be outside of 27
wheel paths and as determined by the Engineer. Traffic control shall be provided by the 28
Contractor as requested by the Engineer. Failure by the Contractor to provide the 29
requested traffic control will result in forfeiture of the request for cores. When the CPF for 30
the lot based on the results of the HMA cores is less than 1.00, the cost for the coring will 31
be deducted from any monies due or that may become due the Contractor under the 32
Contract at the rate of $200 per core and the Contractor shall pay for the cost of the 33
traffic control. 34
35
5-04.3(10)A HMA Compaction – General Compaction Requirements 36
Compaction shall take place when the mixture is in the proper condition so that no undue 37
displacement, cracking, or shoving occurs. Areas inaccessible to large compaction 38
equipment shall be compacted by other mechanical means. Any HMA that becomes 39
loose, broken, contaminated, shows an excess or deficiency of asphalt, or is in any way 40
defective, shall be removed and replaced with new hot mix that shall be immediately 41
compacted to conform to the surrounding area. 42
43
The type of rollers to be used and their relative position in the compaction sequence 44

14
5-04.3(11)A Reject Work General 15
Work that is defective or does not conform to Contract requirements shall be rejected. 16
The Contractor may propose, in writing, alternatives to removal and replacement of 17
rejected material. Acceptability of such alternative proposals will be determined at the 18
sole discretion of the Engineer. HMA that has been rejected is subject to the 19
requirements in Section 1-06.2(2) and this specification, and the Contractor shall submit 20
a corrective action proposal to the Engineer for approval. 21
22
5-04.3(11)B Rejection by Contractor 23
The Contractor may, prior to sampling, elect to remove any defective material and 24
replace it with new material. Any such new material will be sampled, tested, and 25
evaluated for acceptance. 26
27
5-04.3(11)C Rejection Without Testing (Mixture or Compaction) 28
The Engineer may, without sampling, reject any batch, load, or section of Roadway that 29
appears defective. Material rejected before placement shall not be incorporated into the 30
pavement. Any rejected section of Roadway shall be removed. 31
32
No payment will be made for the rejected materials or the removal of the materials 33
unless the Contractor requests that the rejected material be tested. If the Contractor 34
elects to have the rejected material tested, a minimum of three representative samples 35
will be obtained and tested. Acceptance of rejected material will be based on 36
conformance with the nonstatistical acceptance Specification. If the CPF for the rejected 37
material is less than 0.75, no payment will be made for the rejected material; in addition, 38
the cost of sampling and testing shall be borne by the Contractor. If the CPF is greater 39
than or equal to 0.75, the cost of sampling and testing will be borne by the Contracting 40
Agency. If the material is rejected before placement and the CPF is greater than or equal 41
to 0.75, compensation for the rejected material will be at a CPF of 0.75. If rejection 42
occurs after placement and the CPF is greater than or equal to 0.75, compensation for 43
the rejected material will be at the calculated CPF with an addition of 25 percent of the 44
unit Contract price added for the cost of removal and disposal. 45
46
5-04.3(11)D Rejection - A Partial Sublot 47
In addition to the random acceptance sampling and testing, the Engineer may also 48
isolate from a normal sublot any material that is suspected of being defective in relative 49
density, gradation or asphalt binder content. Such isolated material will not include an 50
original sample location. A minimum of three random samples of the suspect material will 51

Correction of defects shall be carried out until there are no deviations anywhere greater 28
than the allowable tolerances. 29
30
Deviations in excess of the above tolerances that result from a low place in the HMA and 31
deviations resulting from a high place where corrective action, in the opinion of the 32
Engineer, will not produce satisfactory results will be accepted with a price adjustment. 33
The Engineer shall deduct from monies due or that may become due to the Contractor 34
the sum of $500.00 for each and every section of single traffic lane 100 feet in length in 35
which any excessive deviations described above are found. 36
37
When utility appurtenances such as manhole covers and valve boxes are located in the 38
traveled way, the utility appurtenances shall be adjusted to the finished grade prior to 39
paving. This requirement may be waived when requested by the Contractor, at the 40
discretion of the Engineer or when the adjustment details provided in the project plan or 41
specifications call for utility appurtenance adjustments after the completion of paving. 42
43
Utility appurtenance adjustment discussions will be included in the Pre-Paving and Pre-44
Planing Briefing (5-04.3(14)B3). Submit a written request to waive this requirement to the 45
