INSTRUCTIONS TO BIDDERS
1. GENERAL
These instructions specify the form and procedures for the submission of a complete and acceptable bid.
(See Bid Form.)
2. EVIDENCE OF QUALIFICATIONS
Upon request of the Owner, a Bidder whose Bid is under consideration for the award of the Agreement
shall submit promptly to the Owner satisfactory evidence of the Bidder's financial resources, their
experience, their performance in completing other projects of a similar nature, and the organization and
equipment they have available for the performance of the Agreement.
3. BIDDER QUALIFICATIONS
Before the Bid is considered for award, the City Engineer reserves the right to determine whether or not a
Bidder is responsible and to require the Bidder to complete a Bidder Qualification Form and/or a current
financial statement prepared by a Certified Public Accountant. The City Engineer shall determine whether
a Bidder is responsible on the basis of the following criteria:
• The skill and experience demonstrated by the Bidder in performing Agreements of a similar
nature.
• The Bidder's record for honesty and integrity.
• The Bidder's capacity to perform in terms of facilities, personnel, and financing.
• The Bidder's past performance under City Agreements. If the Bidder has failed in any material
way to perform its obligations under any Agreement with the City, the Bidder may be determined
as a non-responsible Bidder.
• A Bidder's representations concerning their qualifications will be construed as a covenant under
the Agreement. Should it appear that the Bidder has made a material misrepresentation, the City
shall have the right to terminate the Agreement for the Contractor's breach, and the City may then
pursue such remedies as provided in the Agreement Documents or as provided by state statute,
City code, or as appropriate.
Any determination that a Bidder is non-responsible will be made by the City Engineer. Such
determination will be made in writing to the Bidder setting forth the reasons for such determination.
4. CONDITIONS AFFECTING THE WORK
The Bidder shall examine carefully the site of the proposed work and the Bidding Documents before
submitting a Bid. The submission of a Bid shall be an admission that the Bidder has made such
examination and is satisfied as to the conditions to be encountered in performing the work and as to the
requirements and accuracy of the Bidding Documents.
The City assumes no responsibility for any understanding or representations concerning conditions made
by any of its officers, agents, or employees prior to the execution of this Agreement, unless such
understanding or representations are expressly stated in the Bidding Documents or Addenda.
The Bidder shall include in their Bid sufficient sums to cover all items required by the Agreement and the
conditions of the site(s), and shall rely entirely upon their own examination in making their Bid. The
submission of a Bid shall be taken as prima facie evidence of compliance with this paragraph.
If material required for bidding purposes by these documents is absent, the bidder is required to notify the
City Engineer by facsimile (866) 594-7658, or by e-mail to kkornelis@soldotna.org

each bid as evidence of good faith, a guarantee that if awarded the contract, the Bidder will execute the
contract and give bond as required. All Bidder’s checks or bid bonds will be retained until the successful
bidder has entered into a satisfactory contract and furnished bonds, as required. The successful Bidder
shall furnish the Owner a Performance and Payment bond in the full amount of the Agreement and shall
maintain the Bond in force during the continuance of the Agreement. The bonds must be furnished prior
to the Owner’s execution of the contract. The Bond shall be for the faithful performance of the

alterations, extensions of time, additional work, and other changes authorized by the Agreement
Documents may be made without securing the consent of the Surety or Sureties. Power-of-Attorney for

of claims as provided by that chapter.

in Alaska obtain a license. All bidders are required to furnish, on the Bid Form, a current, valid Alaska

individual or business who is found to be in violation of the Kenai Peninsula Borough Code of

bidding procedure, and to accept any bid presented which meets or exceeds said specifications and which
is deemed to be in the best interest of the City. However, the requirements for timeliness and manual
signatures shall not be waived. The City is not obligated to accept the lowest bid and is not responsible
for bid preparation costs.
14. EXECUTION OF CONTRACTS
The successful bidder shall be required to execute a contract for the work within ten (10) days after
receiving the contract documents from Owner; if Contractor does not return executed copies within this
time, then, at the option of Owner, the bid may be rejected.

It is the intent of the City to award the bid to the lowest, qualified, responsive and responsible bidder.
Unless otherwise stated in the Bid Documents, the Agreement, if awarded, shall be awarded to the
responsible Bidder who submits the lowest responsive bid. When Bid Documents contain a base bid and
alternates, only the total of the base bid and the alternates to be awarded shall be used to determine the
low bidder.

quantities and unit prices and/or the lump sum awarded by the City Engineer and specified in the
Page 6 of 16
Agreement.
On all Bids, Notice of Award or rejection will be given within Forty-Five (45) days of Bid opening. The

disclosing his/her potential conflict, by submitting a letter to the City Clerk’s Office establishing their
“intent to do business with the City”. The contractor for itself and its principal employees, officers,
agents, directors or shareholders covenants that neither the contractor nor any of the listed classes of
individuals has nor shall acquire any interest, direct or indirect, in the project, direct or indirect, to which
the contract pertains which would conflict in any manner or degree with the performance of its work
hereunder. The selected bidder further covenants that in its performance of the contract no person having
such interest shall be employed, without first disclosing his/her potential conflict.

hearing, with notice to interested parties, for redetermination and final award in accordance with law.

STATE OF ALASKA
DEPARTMENT OF LABOR & WORKFORCE
DEVELOPMENT ALASKA EMPLOYMENT
PREFERENCE INFORMATION
By authority of A.S. 36.10.150 and 8 AAC 30.064, the Commissioner of Labor and Workforce
Development has determined the State of Alaska to be a Zone of Underemployment. A
Zone of Underemployment requires that Alaska residents who are eligible under AS
36.10.140 be given a minimum of 90 percent employment preference on public works
contracts throughout the state in certain job classifications. This 90 percent Alaska resident
hiring preference applies on a project-by-project, craft-by-craft or occupational basis
and must be met each workweek by each contractor/subcontractor in each of the
following classifications:
Boilermakers
Bricklayers
Carpenters
Cement Masons
Culinary Workers
Electricians
Engineers and Architects
Equipment Operators
Foremen & Supervisors
Insulation Workers
Ironworkers
Laborers
Mechanics
Millwrights
Painters
Piledriving Occupations
Plumbers & Pipefitters
Roofers
Sheet Metal Workers
Surveyors
Truck Drivers
Tug Boat Workers
Welders
This determination became effective July 1, 2015, and remains in effect through June
30, 2017. This determination will be applied to projects with a bid submission deadline
on or after July 1, 2015 and to projects previously covered by the 2013 Alaska
employment preference determination. This will afford contractors an opportunity to
consider the impacts of Alaska resident hire in their bids.
The first person on a certified payroll in any classification is called the "first worker" and
is not required to be an Alaskan resident. However, once the contractor adds any more
workers in the classification, then all workers in the classification are counted, and the
90 percent calculation is applied to compute the number of required Alaskans to be
in compliance. To compute the number of Alaskan residents required in a workweek
in a particular classification, multiply the total number of workers in the classification by
90 percent. The result is then rounded down to the nearest whole number to determine
the number of Alaskans that must be employed in that classification.
If a worker works in more than one classification during a week, the classification in
which they spent the most time would be counted for employment preference purposes.
If the time is split evenly between two classifications, the worker is counted in both
classifications.
If you have difficulty meeting the 90 percent requirement, an approved waiver must
be obtained before a
non-Alaska resident is hired who would put the
contractor/subcontractor out of compliance (8 AAC 30.081 (e) (f)). The waiver process
requires proof of an adequate search for qualified Alaskan workers. Qualified Alaska
residents identified through the search must be hired before waivers for non-resident
Page 14 of 16
workers may be granted. To apply for a waiver, contact the nearest Wage and Hour Office
for instructions.
Here is an example to apply the 90 percent requirement to four boilermaker workers.
Multiply four workers by 90% and drop the fraction (.90 X 4 = 3.6 - .6 = 3). The
remaining number is the number of Alaskan resident boilermakers required to be in
compliance in that particular classification for that week.
The penalties for being out of compliance are serious. AS 36.10.100 (a) states "A
contractor who violates a provision of this chapter shall have deducted from amounts
due to the contractor under the contract the prevailing wages which should have
been paid to a displaced resident and these amounts shall be retained by the contracting
agency." If a contractor/subcontractor is found to be out of compliance, penalties
accumulate until they come into compliance.
Contractors are responsible for determining residency status. If you have difficulty
determining whether a worker is an Alaska resident, you should contact the nearest
Wage and Hour Office. Contact Wage and Hour in Anchorage at (907) 269-4900, in
Fairbanks at (907) 451-2886, or in Juneau at (907) 465-4842.

Within 20 days after the effective date of the Notice to Proceed and prior to commencement of
work, Contractor shall submit to Owner the construction progress schedule and schedule of values
required in Articles 4.2.2, 4.2.3 and 4.2.4. The schedule of values and progress schedule must be
acceptable to owner and provide reasonable divisions of contract work with corresponding
payment. No payment will be made under this contract prior to completion of this requirement.
4.2.2
In accordance with the Division 1 requirements governing submittals as provided in the contract
specifications, Contractor shall prepare and submit to Owner a detailed progress schedule for the
work which reveals and identifies the critical path of progress, which is consistent with the work
and time required by the contract, and which shall provide for the most expeditious and practicable
execution of the work. Float time between work items is part of the project and not property of the
Contractor. Float time is defined as the amount of time that spans from completion of one
previously scheduled activity and extends to the point at which the next scheduled activity is set to
begin.
4.2.3
Contractor shall also provide Owner with a proposed schedule of values upon submittal of a
detailed progress schedule for the work. The schedule of values shall be allocated to various
portions of the work and be prepared in such a form and supported by such data to substantiate its
accuracy as reasonably required by Owner. Each item of work shall include all applicable profit
and overhead. This schedule of values, unless objected to by owner shall be the basis for progress
payments made to Contractor and shall include specific lump sum amounts for "Final Payment."
This line item shall be in conformance with guidelines specified in ARTICLE 8. Contractor, at the
request of Owner, shall amend the progress schedule and the schedule of values as the work
progresses.

diagrams, or other information necessary to assist Architect in determining whether a proposed
product meets the intent of the contract documents.
4.2.6
Contractor shall also submit physical samples of materials, equipment or workmanship where
required by the contract documents. After approval by Owner and Architect, the sample shall be
established as the minimum standard of work, material, equipment or other quality which will be

4.2.7
Submittal of shop drawings by contractor constitutes a representation by contractor that the
submittal and work, or products required or to be used in accordance with that submittal, will meet
or exceed the criteria and conditions of the contract documents and that performance of the work
identified in those submittals will meet the progress schedule.
4.2.8
Before initiating any work for which shop drawings are required, Contractor shall obtain
Architect’s approval of the shop drawings, which include drawings, diagrams, schedules and other
data specially prepared by Contractor, a subcontractor, a manufacturer, a supplier or distributor to
illustrate in detail that portion of the work. Contractor shall review, approve, and submit all shop
drawings, whether prepared by himself/herself or subcontractor or supplier. It shall be the duty of
Contractor to provide a whole or complete system and to coordinate all work depicted by a
particular shop drawing with the work required by other shop drawings for that portion of the work
or for related or adjacent work.

Contractor shall provide a copy of all transmittal letters to Project Representative at the time the
submittal is made to Architect. Architect will review Contractor's submittals only for conformance
with the design concept of the work and the information given in the contract documents.
Architect's approval of a specific item shall not indicate approval of an assembly of which the item
is a component. Architect will return reviewed submittals to Contractor with written comments
and forward one set to Project Representative with reasonable promptness so as to cause no delay.
A minimum of five (5) sets of submittals shall be required.
4.2.10 Should Architect reject any proposed shop drawings, product data or sample, Contractor shall
resubmit revised drawings, samples or product data and draw Architect's attention to any deviation
or revisions other than those requested by Architect.
4.2.11 All of Contractor's submittals shall be made in conformance with the dates specified in the detailed
progress schedule with reasonable promptness and in such sequence as to cause no delay in the
work of Owner or any separate contractor.
4.3

5.1
DEFINITIONS AND RESPONSIBILITIES
5.1.1
A subcontractor is a person or entity having a direct contractual relationship with Contractor, or
with one of Contractor's subcontractors, to perform any of the work at the site. A supplier is any
manufacturer or person or firm providing materials, equipment or assemblies to Contractor or to
one of the subcontractors for inclusion in this project.
5.1.2
All contracts between Contractor, subcontractors and suppliers (whether or not in privity with
Contractor) shall be in accordance with the terms of this contract and shall incorporate the General
Conditions of this contract. Contractor shall include in such contracts, and require its inclusion in
any subcontracts, a provision holding any subcontractor or supplier (whether or not in privity with

contract documents, or which prevents Contractor or any subcontractor from performing work.
This direct accountability to the Owner shall be in addition to Contractor's liability for any such
failure.
5.1.3
The provisions in this ARTICLE shall not be construed as creating a right of recourse, or any direct
contractual relationship, between Owner or Owner's agents and any subcontractor, supplier, or
manufacturer (whether or not in privity with Contractor).
5.1.4
Contractor shall make all necessary copies of these contract documents available to Owner and to
each subcontractor and shall require each subcontractor to make copies of these contract documents
available to each of Contractor’s subcontractors, if any.

in accordance with Division 1 requirements as provided in the contract specifications.
5.2.2
Rejection of a proposed subcontractor or material supplier shall not entitle Contractor to any
increase in the contract sum or time.

orders for materials and equipment prior to purchase of such items.
5.3
CONTRACTOR PAYMENTS TO SUBCONTRACTORS AND SUPPLIERS
Page 14 of 32
5.3.1
Recognizing the importance of maintaining the integrity of a public contract, Contractor warrants
that Contractor will pay all subcontractors and material suppliers at least monthly on or about the
20th day of each month upon approval of the subcontractors' and materials suppliers' billing, for all
apparently acceptable work performed on the site during the preceding month and for all apparently
acceptable material incorporated into the project or delivered and properly stored at the site during
any month for which Contractor has received payment from Owner. If Owner retains a percentage
of sums due, Contractor may retain a like percentage, but when retainage is paid, Contractor must
pay to the subcontractor or supplier interest on retainage equal to interest rate paid to Contractor
by Owner.
5.3.2
In furtherance of Contractor's warranty under this ARTICLE and ARTICLE 8, Owner, may require
Contractor to declare Contractor’s status of accounts with any or all the subcontractors and
suppliers. A proof of payment to subcontractors and suppliers shall be made in a form acceptable
to Owner. If Contractor breaches this warranty and fails to pay each subcontractor and materials
supplier within 45 days after a monthly billing has been presented, then Owner reserves the right
to withhold sufficient sums from Progress Payments due to Contractor and to issue payment to the
subcontractors or material suppliers directly. This ARTICLE shall not be construed as creating a
right in the subcontractors or material suppliers to have direct recourse against Owner for payment.
Contractor expressly agrees that Owner will not be liable for any exercise of Owner's discretionary
right under this section, and Contractor agrees to release and indemnify Owner for any claims
arising therefrom, either by Contractor directly or by any subcontractor or material supplier.
Likewise, this ARTICLE shall not be construed as creating a right in Contractor's surety or any
other subrogated party to have direct recourse against Owner for failure to withhold sums pursuant
to this section.
ARTICLE 6
SEPARATE CONTRACTS
6.1
Owner has the right to award separate contracts for work on the project that is not included in this
contract.
6.2
When separate contracts are awarded for different portions of the Project or other work on the site,
the term Contractor in the contract documents in each case shall mean the Contractor who executes
each separate contract.
6.3
Contractor shall afford other contractors and Owner's own forces reasonable opportunity for the
introduction and storage of materials and equipment and for the execution of their work and shall

6.4
Any costs caused by defective or ill-timed work under separate contracts shall be borne by the party
responsible thereof and shall be paid promptly.
6.5
If Contractor alleges that delay or additional costs were caused by the letting of separate contracts
or by work performed by Owner's own forces, then Contractor may request an equitable adjustment
by change order as provided below.
6.6
If any part of Contractor's work depends upon work performed by Owner or any separate
contractor, prior to proceeding with the work, Contractor is required to report to Owner any
apparent discrepancies, defects or delays in the other work which impede proper execution of the
work required by this contract. If Contractor fails to report such unsuitable work by another
Page 15 of 32
contractor to Owner, then Contractor shall be deemed to have accepted the unsuitable work and
any liability for all deficiencies, damages and costs which arise as a result of the defective work or
of Contractor's use or covering of the unsuitable work.
6.7
Should Contractor or any subcontractor delay or cause damage to the work or property of any other
contractor or person, Contractor shall repair the damage or settle the claim and shall further, to the
extent allowed by law, indemnify, defend, and hold Owner harmless from any and all claims, costs,
expenses, injury, damages, or loss of any kind, including attorneys' fees, court costs, or arbitration
costs, which arise out of such delay or damage.
6.8
Should a dispute arise between Contractor and separate contractors as to the responsibility for
completing, finishing or cleaning up particular work or a portion of the work, Owner may complete,
finish or clean up the disputed portion and apportion the cost among Contractors responsible as
Owner shall determine to be equitable.

Contractor and Owner expressly agree that Owner shall be entitled to retain from payments to
Contractor amounts in excess of normal retainage if these additional amounts may be necessary to
indemnify Contractor's surety for any payment or corrective work which the surety might be

Contractor's surety specifying the reason for retaining extra amounts, the amounts to be retained
and agreement of the surety to reimburse Owner for any interest which may be due Contractor

Owner at the address designated for legal service in the agreement, at or prior to presentation of the
contract for execution by owner.
7.2.8
There shall be no cancellation or material change of the insurance coverage, or intent not to renew
the insurance coverages as specified in this contract, without thirty (30) days prior written notice
to the City of Soldotna. Notice of cancellation, material change in coverage, or intent not to renew
will be delivered to the address designated for legal notice in the agreement.
7.2.9
Upon renewal or change in policies during the contract, Certificates of Insurance shall be delivered
to the address designated for legal notice in the agreement.

Page 17 of 32
providing coverage against fire and extended coverage perils, may, at Owner option, provide
coverage to the full insurable value of the project and insure the interests of Contractor and all
subcontractors as their interests may appear. Any recovery for loss insured pursuant to this General
Condition is to be adjusted to Owner and made payable to Owner as trustee for the insured, as their
interests may appear. This section does not modify the contractor or subcontractors' responsibility
to provide insurance as required in ARTICLE 7.

ARTICLE 8
MEASUREMENT, PAYMENT AND COMPLETION
8.1
SCOPE OF PAYMENT
8.1.1
Unless altered by change order, Contractor shall be paid only that sum set forth in the agreement
between Owner and Contractor as Contractor's compensation for performance of all work required
by the contract documents.
8.2
LUMP SUM PAY ITEMS
8.2.1
Each bid item is characterized as either a lump sum item or a unit price item in the bid documents.
Where the item is bid at a lump sum price, no additional compensation shall be paid to Contractor
for additional work required because Contractor failed to include items or quantities in Contractor’s
estimate or a subcontractor's estimate, or failed to utilize proper construction means, methods,
procedures or sequence or by virtue of any decision of Contractor.
8.2.2
Contractor is required to provide and pay for all requirements necessary for the proper execution
and completion of the contract unless specifically excluded by the contract documents. The costs
are part of the contract price. The requirements include but are not limited to the requirements
stated in ARTICLE 1.4.
8.2.3
All materials and equipment incorporated in the work shall be new except as otherwise provided in
the contract documents. All materials and equipment shall meet or exceed the requirements of the
plans and specifications and Contractor shall furnish, if requested, satisfactory evidence as to the
source, kind and quality of any materials and equipment.
8.3
UNIT COST ITEMS
8.3.1
Quantities appearing in the bid schedule are approximate and are prepared for comparison of bids.
Payment to Contractor will be for actual quantities of work performed and materials furnished in
accordance with the contract documents. Scheduled quantities of work and materials may be
increased, decreased or eliminated as provided herein.
APPLICATION FOR PAYMENT
8.4
8.4.1
Applications for payment shall be based on Contractor's submitted schedule of values, as approved
by Owner per Section 4.2. Schedule of values shall be prepared in such form and supported by
such data as may be required by Owner to substantiate its accuracy prior to Contractor's first
application for payment.
8.4.2
The schedule of values shall include quantities of work, unit prices and other items comprising the
contract price. It shall subdivide the work into each component part in sufficient detail to serve as
the basis for progress payments during construction.
Page 18 of 32
8.4.3
With each subsequent application for progress payment, Contractor shall provide a schedule of
values to Owner showing all work which has been performed to date together with the value
thereof, and the percentage of work completed.
8.5
PROGRESS PAYMENTS
8.5.1
Progress Payments shall be made monthly, based upon the amount of apparently acceptable work
performed at the site and apparently acceptable materials purchased for the project and properly
stored at the site during the previous month. Disbursement of progress payments will not effect a
transfer of the risk of loss from the Contractor to the Owner for invoiced equipment or material.
The risk of loss of the work and all material and equipment not yet incorporated in the work is the
liability of the Contractor until substantial or final completion, whichever is earlier.
8.5.2
The value of work performed and materials stored shall be set forth in Contractor's revised schedule
of values. If requested by Owner, Contractor shall promptly provide Owner any additional
information necessary to ascertain the value of the work performed or the cost of materials stored
at the site during the previous month. Each updated Schedule of Values shall be in the form of a
notarized affidavit. Proof of certified payroll shall be provided per ARTICLE 4.
8.5.3
By application for payment, Contractor warrants and guarantees to Owner that title to all work,
materials, and equipment for which payment is requested will pass to Owner either by incorporation
in the construction and after substantial completion or upon receipt of payment, whichever occurs
later, that such title will be clear of all liens, claims, security interests, and other encumbrances,
except for liens to be released later prior to final payment and specifically identified on the
application for payment, and that all such work, materials, and equipment are of acceptable quality.
8.5.4
Each application for payment shall be made no later than the tenth day of each month for work
performed during the preceding month. Progress Payment requests shall be submitted to Project
Representative for analysis and recommendation to Owner.
8.5.5
Project Representative will review Contractor's application for payment within seven (7) working
days after receipt and if Project Representative ascertains that the amounts set forth therein are
properly due and owing to Contractor, then Project Representative shall issue a Certificate of
Payment to Owner. If Project Representative determines that only a portion of the sum requested
is then properly due and owing to Contractor, then Project Representative may issue a Certificate
of Payment in a lesser amount or may reject the application altogether. Project Representative will
notify in writing both Contractor and Owner of the reasons for reduction or rejection of any
application for Progress Payment.
8.5.6
Project Representative's issuance of a Certificate of Payment constitutes a representation that the
work has progressed to the point indicated and that to the best of Project Representative's
professional knowledge and information, Contractor is entitled to payment in the amounts certified.
8.6
RETAINAGE
8.6.1
After receipt from Project Representative of the Certificate for Payment, Owner shall make
payment to Contractor within thirty (30) days. Owner shall have the option to retain up to 10% of
the full amount of the Certificate for Payment plus lump sum amounts for material and equipment
not properly stored, or subject to damage prior to use. Amounts retained by Owner may be held
by Owner until project completion. If the project involves grant money or the city has entered into
Page 19 of 32
a written contract with the state to provide state funds, payment will be made in accordance with
AS 36.90.200-270.
8.6.2
Owner may withhold additional sums of money from progress payments in an amount sufficient to
safeguard and protect Owner against any apparently meritorious claims against Contractor by any
party other than Owner, and for any work which Owner ascertains to be defective or not meeting
the requirements of the contract documents.
8.7
CONDITIONS OF PAYMENT
8.7.1
Project Representative may refuse to approve all or any part of any request for progress payment
if, in Project Representative's opinion, it would be incorrect to make the representation to Owner
set out in ARTICLE 8. Project Representative may also refuse to approve all or any part of any
request for progress payment, if subsequently discovered evidence or the results of subsequent
inspections or tests nullify any payment previously approved.
8.7.2
Owner may withhold payment to the extent necessary to protect Owner from loss resulting from:
A.
B.
C.
D.
E.
F.
G.
H.
I.
Defective or damaged work;
Claims or liens which have been filed or may be reasonably expected;
Contract price reduction by modifications or change orders;
Owner cost to correct or complete defective work;
Unsatisfactory prosecution of the work by Contractor, including but not limited to failure
to furnish adequate submittals or to clean up the work or site;
Reasonable evidence that the work cannot be completed for the unpaid balance of the
contract sum;
Failure of Contractor to make payment properly due to subcontractors, employees,
suppliers or utilities;
Reasonable evidence to believe the work cannot be completed within the contract time.
Damage to Owner's property not replaced or repaired in timely manner.
When the grounds for withholding payment are removed, payment shall be made for amounts
withheld.
8.7.3
Neither the issuance of a Certificate of Payment, nor the making of any progress payment, nor the
partial or entire use of the project by Owner shall constitute an acceptance of any work not in
accordance with the contract documents nor shall it constitute a waiver of any right accruing to
Owner or of any duty of Contractor.
8.8
SUBSTANTIAL COMPLETION
8.8.1
Substantial Completion is defined as the state of construction at which the work is sufficiently
complete and in accordance with the contract documents, so that Owner could occupy and utilize
the work or a specific portion of it, for its intended use.
8.8.2
When Contractor considers the work substantially complete Contractor shall notify Project
Representative in writing and request a Substantial Completion inspection. The notice shall include
a comprehensive list of items to be completed, reasons they are not completed and a date of
anticipated completion. The notice shall also include copies of all code compliance inspections,
the Certificate of Occupancy, if applicable, and any other documents required by the contract.
Page 20 of 32
8.8.3
Project Representative shall schedule the Substantial Completion inspection and notify Contractor.
The inspection will be performed by Project Representative, Architect, Design Engineers, and
Owner personnel in the presence of Contractor. Should this inspection find the work not
substantially complete, Owner may terminate the inspection and promptly notify Contractor in
writing of the conditions for reinspection. Any deficiencies identified by this inspection will be
listed and promptly furnished to Contractor for remedial action.
8.8.4
If Contractor has requested that Project Representative and Owner make an inspection to ascertain
Substantial Completion, and if the work is not then substantially complete, Contractor shall be
liable for all costs Owner, Architect, and Project Representative have incurred in making the
inspection.
8.8.5
If it is determined on the basis of inspection that the work is substantially complete, Project
Representative will issue a Certificate of Substantial Completion. Included in the certificate shall
be a list of items which must be completed or corrected before final payment and the time within
which such items shall be complete and corrected. Failure to include an item on this list does not
alter the responsibility of Contractor to complete all work in accordance with contract requirements.
8.8.6
Certificate of Substantial Completion shall state the date of Substantial Completion and the
respective responsibilities of Owner and Contractor for the maintenance, insurance and security of
the work. Certificate of Substantial Completion shall specifically authorize Owner to take
possession of the premises and utilize them for their intended purpose. Owner's beneficial
occupancy of the premises shall make reasonable allowance for the performance of the work which
Contractor must complete prior to final completion.
8.8.7
If Contractor fails to complete or correct work required by the Certificate of Substantial Completion
within the time allowed, then the Certificate of Substantial Completion shall be voided and the
contract time expended by Contractor shall be counted, and the acceptability of the work shall be
inspected as if a Certificate of Substantial Completion had not been issued.
8.8.8
Upon Substantial Completion of the work and upon application by Contractor and certification by
Project Representative, Owner shall make payment, reflecting adjustment in retainage, if any, for
such work as provided in the contract documents.
8.9
FINAL COMPLETION AND WARRANTY PERIOD
8.9.1
The terms Final Completion and Warranty Period refer to, respectively, the finalization of the
construction phase and a one-year warranty period following the Substantial Completion. Final
Completion shall be represented by a lump sum dollar amount identified on the schedule of values.
Final Payment represents a sum of money to perform all tasks necessary from Substantial
Completion to Final Completion, including completion of final punch list, completion of as-built
data, turnover of all warranty information, notarized acknowledgments of payments, and
relinquishment of claims against Owner.
8.9.2
When Contractor considers the work ready for Final Completion, Contractor shall forward to
Project Representative an application for final payment including (1) an affidavit that all payrolls,
bills for materials and equipment, and other indebtedness connected with the work have been paid
or otherwise satisfied, (2) consent of surety, if any, to payment, (3) irrevocable, notarized proof of
payment and relinquishment of claim against Owner, issued by every subcontractor (whether or
not in privity with Contractor), material supplier and other party who might assert a claim against
Owner, and (4) all other documentation required by the contract documents. Project Representative
Page 21 of 32
and Owner shall promptly inspect the work to see that it is fully performed and complete, that all
portions of the work are acceptable and that the contract is fully performed aside from completion
of the Warranty Period. After Project Representative has made a determination that these
requirements have been met, Project Representative shall prepare and recommend that Owner issue
a Certificate of Final Completion and Final Payment.
8.9.3
Project Representative's approval of Final Payment constitutes an additional representation by
Project Representative to Owner that to the best of Project Representative's knowledge and
information, all conditions which Contractor must fulfill prior to being entitled to Final Payment
have in fact been fulfilled in accordance with the contract documents.
8.9.4
If any party refuses to relinquish its claim, or if Owner considers that any item or portion of the
work: (1) is of doubtful acceptability under the contract documents; or (2) may diminish the value
of the work; or (3) may prove to be ultimately unreliable; or (4) may prove to be less functional
than required by the intent of the contract, then Owner, in lieu of refusing Final Payment to
Contractor, may allow Contractor to furnish a bond in a form and in an amount satisfactory to
indemnify Owner against losses occasioned thereby. If any additional costs to settle the claim or
to correct work of doubtful quality accrue to Owner in excess of the indemnity available to Owner,
Contractor shall refund to Owner all differences and costs which Owner might be compelled to
pay, including all litigation costs and reasonable attorney fees.
8.9.5
Acceptance of final payment by Contractor constitutes an explicit waiver of all claims which
Contractor might assert against Owner except those previously made in writing and identified by
Contractor as unsettled at the time of the Application for Final Payment.
8.9.6
Final Payment to Contractor shall constitute a waiver of all claims which Owner might assert except
those arising from: (1) unsettled claims; (2) faulty or defective work (3) failure of the work to
comply with the requirements of the contract documents; (4) warranties required by this contract
or that by their terms do not expire upon completion of the contract.
8.9.7
If, after Substantial Completion, Warranty Completion is delayed through no fault of Contractor,
or by the issuance of change orders affecting Final Completion, Owner may, upon recommendation
of the Project Representative, extend the contract time by a reasonable period and accept certified
applications for further Progress Payments.
The contract sum identified on the schedule of values as "Final" shall be based on the contract
award in an amount as follows:
8.9.8

Final Payment shall be released to Contractor along with the Certificate of Final Completion. Upon
issuance of Certificate of Final Completion all contract sums shall be accounted for to Contractor
Page 22 of 32
and shall be paid to Contractor. However, any and all applicable bonds shall not be released until
after the Warranty Period.
8.10
TIME AND LIQUIDATED DAMAGES
8.10.1 The time permitted for construction of the work will run from issuance of Notice to Proceed through
the dates for Substantial Completion as specified in Agreement between Owner and Contractor,
unless a specific completion date is specified.
8.10.2 The term "day" as used in this contract shall mean "calendar day" unless specifically stated
otherwise.
8.10.3 All warranty periods and obligations accruing to Contractor through completion of the work shall
be considered to begin on the date of Substantial Completion, unless otherwise agreed to separately
in writing by Owner and Contractor.
8.10.4 Contractor shall begin the work as soon as possible after the date identified in Notice to Proceed
and shall prosecute the work expeditiously and with adequate labor and materials.
8.10.5 Liquidated damages will, if agreed to by the parties and set out in the Agreement, be applied in the
amount set out in the Agreement.
8.10.6 Claims for extension of time will be considered only if they affect "critical path" items
specifically identified in the detailed progress schedule or in any applicable Supplementary
Conditions. Claims for extension of the contract time must be made in writing to Owner not
more than twenty (20) days after the reason for requested extension appears.
ARTICLE 9
CHANGES IN THE WORK, CONTRACT PRICE, AND TIME
9.1
CHANGE ORDERS
9.1.1
Without invalidating this contract, Owner may, at any time, order additions, deletions, or revisions
in the work. All such changes must be authorized by written change order. Upon receipt of a
change order, Contractor shall proceed with the work in accordance with applicable requirements
of the contract documents. If any change order entails an increase or decrease in the contract price
or an extension or curtailment of the contract time, adjustment will be made as provided herein.
9.1.2
Extra work will be paid for either at a fixed price specified in the change order (using unit prices
or a lump sum amount) or on a time and materials basis.
9.1.3
Project Representative may authorize minor changes, alterations or deviations in the work in
accordance with ARTICLE 2. These changes shall be authorized by written Field Order to be
included in a subsequent Change Order.
9.1.4
Any additional work performed by Contractor without a properly executed change order will not
entitle Contractor to an increase in the contract amount or to an extension of the contract time,
except in the case of emergency threatening life, safety or property.
9.2
ISSUANCE OF CHANGE ORDER
Page 23 of 32
9.2.1
The contract sum constitutes the total compensation to Contractor for the work required by this
contract. The contract price may be changed only by a properly executed change order. Any
request for increase in the contract price shall be based upon written notice delivered to Project
Representative within ten (10) days after the reason for the proposed increase appears. Change
order proposals must be accompanied by all pertinent data and documentation, including a detailed
estimate showing costs, quantities, unit prices and markups for overhead and profit.
9.2.2
Project Representative shall analyze Contractor's change order proposal and shall make a
recommendation to Owner within a reasonable period of time. If Owner accepts the proposal,
Project Representative shall prepare the change order for execution by Contractor and Owner.
9.2.3
The value of any work added or deleted by change order shall be determined by one of the following
methods:
A.
Application of unit prices set forth in the bid: unit prices shall include all direct and indirect
costs of the work, including labor, equipment (whether owned or rented), materials, home
office expense, all overhead and profit. For unit price change orders involving credits to
Owner, unit prices applied shall be 90% of the bid unit price.
B.
Application of mutually accepted unit prices for work not covered by bid unit prices: unit
prices shall include all direct and indirect costs of the work, including labor, equipment
(whether owned or rented), materials, home office expense, all overhead and profit.
Mutual acceptance of a lump sum: Contractor's lump sum proposal must include an
itemized breakdown of all costs of Contractor, subcontractors and suppliers. Breakdowns
shall show quantities and prices of labor, materials, equipment and other direct costs. To
direct costs shall be added the allowable combined overhead and profit as provided in
ARTICLE 9.4.
C.
D.
At Owner's option, Contractor may be directed to proceed with additional work on a "time
and materials" basis which may also stipulate a maximum "not to exceed" amount.
Contractor will be required to maintain and submit detailed records showing all quantities
and prices of labor, materials, equipment and other direct costs. To direct costs shall be
added the allowable combined overhead and profit as provided in ARTICLE 9.4.
9.2.4
When both additions and credits for related work or substitutions are involved in any one change,
the allowance for overhead and profit shall be based on the net change. All related items within a
proposal shall be considered as a single item for purposes of computing overhead and profit.
9.2.5
When Contractor is directed to proceed on a time and materials basis, costs of the work shall be
submitted daily for approval by Project Representative and may only include:
A.
Actual payroll costs for employees, as substantiated by time cards, in the direct
employ of Contractor for the times actually utilized in prosecution of the additional work,
including allowance for benefits which Contractor customarily provides its employees;
B.
The actual substantiated cost to Contractor for all material and equipment
incorporated into the work, including transportation and storage expenses;
C.
The actual substantiated amounts of payments by Contractor to subcontractors for
work performed by the subcontractors;
Page 24 of 32
F.
I.
D.
Any costs of special consultants to the extent authorized by Owner:
E.
Substantiated equipment rental costs at reasonable market rates;
Additional supervision and travel costs reasonably related to the work performed;
G.
Increased bond premiums:
H.
Additional license fees, permits, or applicable taxes;
Minor incidental expenses such as telegrams and long distance telephone charges.
To these direct costs shall be added the allowable combined overhead and profit as provided in
ARTICLE 9.4.
9.2.6
Unless specifically agreed to by Owner in writing, the cost of additional work shall not include any
portion of Contractor's general overhead, nor any sum attributable to Contractor's prosecution and
supervision of the principal work at the site, nor any overtime expense, unless specifically agreed
to by Owner in writing. Contractor shall not be compensated for any casualty or other losses or
expenses attributable to negligence of Contractor or any person in its employ or any subcontractor
or supplier.
9.2.7
Payment to Contractor shall be made only for the actual quantities of work performed and accepted
or materials furnished, in conformance with the contract or applicable change order. When the
accepted quantities of work or materials vary from the quantities stated in the bid schedule,
Contractor shall accept as payment in full, payment at the original contract unit prices for the
quantities of work and materials furnished, completed and accepted; except as provided in the
contract documents.
9.3
UNIT PRICES
9.3.1
When unit prices are used, and where the final quantity of a major contract item varies more than
25% above or below the bid quantity, either party to the contract may request an equitable
adjustment in the contract unit price of that item. A major contract item is an item equal to 10% or
more of the total contract.
9.3.2
When the final quantity of work is less than 75% of the bid quantity, the equitable adjustment shall
be made for those units of work done and accepted, except that the total payment for the item shall
not exceed 75% of the total amount bid for the item.
9.3.3
To determine unit prices for authorized changes or additions in the work that alter the quantity of
work under a lump sum pay item, adjustment to the pay item will be determined by multiplying the
added or deleted quantity by the quotient of the contract lump sum price and the estimated quantity
shown on the original plans. Payment will be made under a new contract item established for that
purpose. Adjustments will be made as a change order to the contract.
9.3.4
No allowance shall be made for any increased expenses, loss of expected reimbursement or loss of
anticipated profits suffered or claimed, either directly from such alterations in quantities or
indirectly from unbalanced allocations among the contract items by Contractor, or any other causes.
9.4
ALLOWABLE OVERHEAD AND PROFIT
Page 25 of 32
9.4.1
When the value of change order work is determined by the lump sum method or by the time and
materials method, the following definitions and percentages shall apply.
9.4.2
Direct costs are defined as the net cost to Contractor to accomplish a given change. Costs of bonds
and insurance associated with the change shall be applied after addition of indirect costs.
9.4.3
Indirect costs are defined as general operational charges relating to the accomplishment of a given
change, including but not limited to small tools, incidental job burdens and general office expense.
9.4.4

(b)
8% of the direct costs of equipment.
(3) In no case shall overhead and profit exceed 23% of the direct costs of work or 16% of
the direct costs of equipment when the cost of the work exceeds $1,000.00. In no case
shall overhead and profit exceed 28% of the direct costs of work or 16% of the direct
costs of equipment when the cost of the work is equal to or less than $1,000.00.

9.5
CONCEALED CONDITIONS
9.5.1
This ARTICLE applies only when concealed conditions substantially at variance with the
conditions set forth in the contract documents are encountered and these conditions were not
foreseeable by Contractor or reasonably inferable from information provided by Architect or
Owner in the bidding documents.
9.5.2
If it is determined the Contractor could not predict the concealed conditions as set forth under
ARTICLE 9.5.1, Owner may issue a change order for the performance of additional work required
with an equitable adjustment in the contract sum. Contractor shall not begin work upon any
concealed condition until Owner has approved a written change order
ARTICLE 10 TESTING AND CORRECTION OF WORK
10.1
TESTS AND INSPECTIONS
Page 26 of 32
10.1.1 Contractor shall be responsible for securing permits and approvals from entities having jurisdiction
over the work. Owner will provide any special testing or inspections required by the contract
documents. Contractor shall not cover work that requires testing, inspection or approval until such
testing, inspection, or approval has been completed.
10.1.2 Contractor shall give Owner timely notice of readiness of the work for all inspections, tests or
approvals. Minimum time required for giving notice of readiness will be agreed upon by Owner
and Contractor prior to startup of work.
10.1.3 Neither observation by Owner nor inspections, tests, or approvals by Owner or Owner's testing
agency shall relieve Contractor from Contractor's obligation to perform the work in accordance
with the contract documents.
10.2
UNCOVERING OF WORK
10.2.1 If any work is covered or buried contrary to contract requirements or Owner's written request, such
work shall be uncovered at Owner's request for inspections, tests or approvals. Uncovering and
recovering shall be at Contractor's expense, unless Contractor has given notice of intent to cover
the work and Owner has not acted with reasonable promptness to provide any necessary tests,
inspections or approvals.
10.2.2 If any work has been covered which Owner has not specifically requested to observe prior to
covering, or if Owner considers it necessary or advisable that covered work be inspected or tested
by others, then Contractor shall, at Owner's request, uncover, expose or otherwise make available
for observation, inspection, or testing, that portion of the work as Owner may require. Contractor
shall furnish all necessary labor, materials and equipment. If such work is found to be defective,
Contractor shall bear all expenses, including compensation for any additional professional services
and testing. If, however, the uncovered work is found not to be defective, Contractor shall be
allowed an equitable adjustment in the contract price or the contract time. Only Contractor's direct
costs attributable to the uncovering of work and its recovering shall be allowed.
10.3
DEFECTIVE WORK
10.3.1 All work not meeting the requirements of the contract documents shall be considered defective.
10.3.2 Contractor shall promptly correct or replace any defective work. Any and all costs associated with
correction or replacement shall be borne by Contractor. Contractor shall also bear the expense of
making good all work of others destroyed or damaged or required to be redone because of the
correction or replacement of defective work.
10.3.3 If, after seven (7) days written notice to Contractor, Contractor fails to correct deficiencies or to
provide Owner with an approved schedule for correcting defective work, Owner may, without
prejudice to any other remedy it may have, make good deficiencies and deduct the cost thereof
from the payment then or thereafter due Contractor. No extensions of time shall be allowed for
correction of work that is defective.
ARTICLE 11 WARRANTIES
11.1
Contractor unconditionally warrants for a period of one year from issuance of the Certificate of
Substantial Completion the usability and quality of all work, labor and materials incorporated into
Page 27 of 32
the project, unless otherwise provided in the contract documents. After the approval of Final
Payment and prior to the expiration of one year after the date of Final Completion, any work found
to be defective shall be remedied promptly by Contractor within fourteen (14) days of written notice
without cost to Owner and in accordance with Owner's written instructions. Contractor shall either
correct such defective work, or, if it has been rejected by Owner, remove it from the site and replace
it with acceptable work. If Contractor does not promptly comply with the terms of Owner's
instructions, Owner may have the defective work corrected or the rejected work removed and
replaced, and all direct and indirect costs of such removal and replacement, including compensation
for additional professional services, shall be deducted from Warranty Period Payment, unless the
surety elects to remedy deficiency.
11.2
In addition to other warranties set forth in this contract and in accordance with requirements stated
in the contract documents, Contractor shall obtain and transmit to Architect all warranties on
material and equipment incorporated into the work and either provided by the supplier or otherwise
required by the contract documents. Transmittal of warranties to Owner shall be a prerequisite of
the Certificate of Final Completion.
11.3
All material and equipment installed by Contractor shall have a manufacturer's warranty for a
period of one year, except as otherwise provided by the contract documents. The period of warranty
shall begin on the date of Substantial Completion unless otherwise noted on the Certificate of
Substantial Completion. This article does not limit any manufacturer's warranty which extends for
a period of time longer than that specified as minimum in the contract documents.
11.4
If a warranty period in excess of one year on a particular item or part of the work is required by the
contract documents, the longer warranty period shall govern warranty obligations of Contractor.
11.5
Owner may accept defective work or materials found during the warranty period instead of
requiring correction or removal and replacement. If acceptance occurs prior to approval of final
payment, a change order shall be issued to reduce the contract price. If acceptance occurs after
approval of final payment, an appropriate amount shall be paid by Contractor to Owner.
The provisions of this ARTICLE shall not be construed as limiting the right of Owner to make a

ARTICLE 13 TERMINATION OF THE CONTRACT OR SUSPENSION OF THE WORK
13.1
TERMINATION BY OWNER
13.1.1 Owner shall have the right to terminate the contract if Contractor should file for bankruptcy,
reorganization, otherwise be declared insolvent, or if Contractor makes a general assignment for
the benefit of creditors. Exercise of these rights, where required by law, is contingent upon relief
from the automatic stay provisions of the United States Bankruptcy Court or through other
appropriate court order. This right of termination is in addition to the right of Owner to terminate
for cause outlined below and other rights of termination as stated in the contract documents.
Page 29 of 32
13.1.2 Termination for cause: If Contractor: (1) repeatedly refuses or fails to supply enough proper skilled
workmen; or (2) fails to pay promptly all subcontractors, suppliers, or other parties as set out in the
contract documents; or (3) fails to adhere in all respects to the provisions of Title 8, Chapter 30, of
the Alaska Administrative Code and Title 36 of the Alaska Statutes as applicable to this contract
and all other pertinent statutes, ordinances or regulations or orders of any local, state, or federal
authority concerning payment; or (4) allows insurance to lapse; or (5) if after seven (7) days written
notice, without prejudice to any other remedy of Owner, Contractor fails to correct to Owner’s
satisfaction deficiencies in work that does not conform to the contract documents; or (6) allows a
situation that creates a danger to person or property to arise. Where an emergency situation creating
a danger to person or property arises, Owner may at its option terminate the contract and take
possession of the site and any of Contractor’s equipment and material necessary to complete an
emergency response or hire a separate contractor to complete the emergency response. Contractor
shall be paid the contract rate for the material used and shall be paid for the use of Contractor’s
equipment at the price shown in the contract documents or at the rate for such equipment listed
in RENTAL RATE BLUE BOOK FOR CONSTRUCTION EQUIPMENT, published by
Machinery Information Division of K-III Directory Corporation, 1735 Technology Drive, Suite
410, San Jose, California 95110. If the rate for such equipment is not so listed, reliable sources
will be used to determine a reasonable rate.
13.1.3 In the event of termination for cause, Owner shall have the right of set-off, from any payment due
Contractor, of all expenses, costs, and damages including but not limited to all professional and
legal expenses and attorneys’ fees and costs or other additional expenditures necessary to complete
the projects that are occasioned by the termination. In the event such amounts exceed the amount
of payment withheld, Contractor shall be liable to Owner for such amounts. No payment shall be
made to Contractor prior to determination that a balance is due Contractor after the amount of setoff is determined.
13.1.4 Owner may terminate this contract at any time for the convenience of Owner for any reason deemed
by Owner to be in the best interest of Owner.
13.1.5 If this contract is terminated for convenience, Contractor will be directed to make all necessary
preparations for closing out the project and for safeguarding Owner's materials and the work
already completed. Contractor will be paid for all conforming work done to date and for all
materials delivered to the site and already paid for by Contractor, together with all reasonable costs
directly attributed to termination, including fixed overhead. Contractor shall be responsible for
minimizing the extent of such expenses and shall not be paid for expenses which could have been
reasonably avoided. On the date that notice of termination or suspension for convenience is issued,
Contractor shall immediately take all actions necessary to stop orders of material, rental of
equipment or premises, employment of persons on the project, and shipment of materials not yet
delivered to the site. The notice of termination or suspension for convenience shall specify a date
by which all steps necessary for termination shall be completed and by which Contractor shall have
removed any unused material and all Contractor’s equipment and forces. Contractor shall leave
the premises in a clean and safe condition on or prior to the date specified in the notice. Owner
shall certify that all termination procedures have been completed and that the premises have been
turned over to the possession of Owner. Within fifteen (15) days after that certification by Owner,
Contractor shall render to Owner a bill for all expenses incurred in termination and for all work
done subsequent to the last progress payment. Owner shall pay Contractor all sums properly due,
together with any retainage not necessary to cover apparently nonconforming work or other
changes, within fifteen (15) working days after the bill has been received by Owner, provided that
Owner has received releases for all liens.
Page 30 of 32
13.1.6 If Contractor is terminated for cause or default on this contract, the performance bond surety shall
commence performance within fourteen (14) days of the termination or default. If the surety does
not arrange for or commence performance by that date, Owner shall have the option to complete or
arrange for performance and the surety shall not be relieved of any responsibility for payment of
costs of performance.
13.1.7 Should Owner elect to terminate Contractor's services prior to final completion of the work, such
termination shall not affect any rights Owner might assert against Contractor at time of termination
or thereafter. Any retention or payment of monies by Owner to Contractor shall not release
Contractor from that liability.
13.2
SUSPENSION OF THE WORK
13.2.1 Owner may, at any time and for any reason, suspend the work or any portion of it for a period not
to exceed ninety (90) days, by written notice delivered to Contractor thirty (30) days prior to the
date fixed for suspension. The notice of suspension shall fix the date on which the work is to be
resumed and Contractor shall resume the work on the date so fixed. Equitable adjustment in the
contract price, the contract time, or both shall be made for cost or delay directly attributable to
suspension of the work.
13.3
TERMINATION BY CONTRACTOR
13.3.1 If through no act or fault of Contractor, Owner orders a suspension of work for a period of more
than ninety (90) days, Contractor may, upon thirty (30) days written notice to Owner, terminate
this contract and recover from Owner payment for work accepted to date plus purported overhead
and profit in the manner provided in ARTICLE 9.4. Contractor shall also have the right to terminate
this contract if Owner fails within forty-five (45) days to pay amounts properly due Contractor for
satisfactorily accomplished work, so certified by Project Representative, as due and payable. The
provisions of this section do not include amounts ordinarily retained from Contractor's Application
for Payment or amounts retained because of unsatisfactory, defective, or incomplete work, or for
any other reason provided in the contract documents.

reason, it shall be considered as severed from the contract documents, and the remaining portions
of the contract documents shall stand as if that provision had never been included in the contract
documents. In the event the unenforceable or void provision is legally essential to the continuing
existence of the contract, the parties shall attempt to substitute a reasonable replacement provision.
14.4
No general condition stated in these provisions or other provision in the contract documents
lessens, alters, or makes inapplicable the requirement for indemnification stated in
Page 31 of 32

grounds for additional payment. It shall be the Contractor's responsibility to familiarize himself with the
depth of the main line utilities and storm drain systems for the project. The Contractor shall excavate for
service connections in such a manner that the excavation is ninety (90) degrees to the street line,
whenever possible. The ditch shall be long enough to allow the
service connection to be stubbed at the property line.
Trenches shall be of sufficient width at the bottom to allow for laying of the particular service (minimum
two and one-half feet [2-1/2’] for single service). Excavation of all fill materials to virgin ground is
required to provide safety for workmen utilizing the trench.
The Contractor shall be responsible for, and shall bear expenses incurred, in the event that a main line
utility should be damaged during excavation or backfilling.
It shall be the responsibility of the Contractor during construction to keep all embankments and
excavation well shaped and drained. The subgrade shall be maintained, compacted in cut sections if
required, and kept free of leaves, sticks, and other debris.
The Contractor shall perform all Work necessary to prevent flow and accumulation of surface water or
ground water in trenches. Unless otherwise provided in the Special Provisions, all Work associated with
pumping or dewatering shall be considered a responsibility of the Contractor and shall be accomplished at
no additional cost to the Owner.

Refer to Section 30.01, Article 1.3, SubArticle G. – Curing Materials.
D. Forms
Forms may be of wood or metal or any other material at the option of the Contractor, provided
that the forms as set will result in a curb, or curb and gutter of the specified thickness, cross
section, grade and alignment shown on the Drawings.
Forms may be removed on the day following pour if the concrete is sufficiently set that removal
can be accomplished without danger of chipping or spalling. Form materials shall be free from
warp, with smooth and straight upper edges, and if used for the face of a curb, shall be surfaced
on the side against which the concrete is to be placed. Wooden forms for straight work shall
have a net thickness of at least one and one-half inches (1.5”). Metal forms for such a work shall
be of a gage that will provide equivalent rigidity and strength. Curb face forms used on
monolithic curb and gutter construction shall be a single plank width when the curb face is ten
inches (10”) or less, except for those used in curb returns. All forms used in curb returns shall
not be less than three-quarters inches (3/4”) in thickness, cut in the length and radius as shown
on the Drawings, and held rigidly in place to line and grade by the use of metal stakes and
clamps. The curb face form shall be cut to conform exactly with the curb face batter as well as
being cut to the required length and radius. Forms shall be of sufficient rigidity and strength, and
shall be supported to adequately resist springing or deflection from placing and tamping of
concrete.
Form material shall be clean and free from defect at the time of use.
All forms including back planks of curb shall be set with upper edges flush with specified
alignment and grade of the finished surface of the improvements to be constructed, and all forms
shall be not less than a depth equivalent to full specified thickness of the concrete to be placed.
Forms shall be held securely in place by means of metal stakes driven in pairs at intervals not to
exceed three feet (3’), one at the front form and one at the back form. Clamps, spreaders, and
braces shall be used to the extent as may be necessary to insure proper form rigidity. Forms for
walk and similar work shall be firmly secured by means of stakes driven at intervals not to exceed
four feet (4’). Form stakes shall be of sufficient size and be driven so as to adequately resist
lateral displacement.
Page 40 of 103
Commercial form clamps for curb and gutter may be used provided they fulfill the requirements
specified herein.
Pump trucks may be used upon approval of the Engineer. Prior to approval, the Contractor must
demonstrate to the satisfaction of the engineer that the pumping equipment will not segregate,
or in any other way degrade, the concrete. Additional test samples for such alternate placement
methods may be taken from the discharge side of the machine for compressive strength
determination assurance tests.
A. Erecting Forms
All forms shall be set to the lines, grade, and dimensions shown on the Drawings. The forms shall
be thoroughly braced and secured to resist deformation or displacement under load, and shall be
installed to permit easy removal without hammering or prying against the fresh concrete. The top
of the forms shall not deviate more than one-eighth inch (1/8”) in ten feet (10’), and the
alignment of forms shall be within one-fourth inch (1/4”) in ten feet (10’).
Before placement of concrete, steel forms shall be lightly oiled with a good grade of form oil.
Excess oil shall be removed by wiping with clean rags, dampened in diesel or fuel oil. Wooden
forms may be oiled in the same manner as metal forms, or they may be watered immediately in
advance of the placement of concrete. Watering of the form shall be done with clean water of
the same quality as that specified for mixing water, and only when the atmospheric temperature
is not less than forty degrees (40deg) Fahrenheit. Concrete shall not be placed until all forms
have been inspected and approved by the Engineer. Wherever form work is exposed to
pedestrian traffic, bridges (not attached to the forms) shall be provided at all regular pedestrian
crossings where it is required to maintain safety standards. Barricades and other safety features
shall be installed as necessary.
B. Placing Concrete
Prior to the delivery of the first load of concrete for curbs, the Contractor shall furnish rigid
straightedges, ten feet (10’) or sixteen feet (16’) in length, to the Engineer for checking surface
uniformity. String shall not be used as a straightedge. Surface irregularities, as measured along
the top face of curb and the curb pan, shall not exceed three-sixteenth inch (3/16”) within ten
feet (10’), or five-sixteenth inch (5/16”) within sixteen feet (16’). Non-conforming surfaces shall
be subject to rejection by the Engineer. All surfaces rejected by the Engineer shall be corrected
by the Contractor at the Contractor’s expense.
The subgrade shall be properly compacted and brought to specified grade in accordance with the
Drawings before placing concrete. The subgrade shall be thoroughly dampened immediately prior
to the placement of the concrete. Forms shall not be splashed with concrete in advance of
placing.
Concrete shall be discharged from transport vehicle to the point of final placement in a
continuous manner as rapidly as practicable. The rate of placement shall not exceed the rate at
which the various placing and finishing operations can be performed in accordance with these
Specifications. Concrete shall not be allowed to free fall more than three feet (3’).
If concrete is to be placed by the extruded method, the Contractor shall demonstrate to the
satisfaction of the Engineer that the machine is capable of placing a dense, uniformly compacted
Page 41 of 103
concrete to exact section, line and grade. Extruded curb which does not meet all requirements of
the Contract Documents, shall be replaced at the Contractor's expense.
C. Stripping Forms and Finishing
The face form of the curb shall be stripped at such time in the early curing as will enable
inspection and correction of all irregularities that appear thereon.
Forms shall not be removed until the concrete has set sufficiently to retain its true shape. The
face of the curb shall be troweled with a tool cut to the exact section of the curb and at the same
time maintain the shape, grade, and alignment of the curb. Both front and back edges shall be
troweled to a radius of one-half inch (1/2”). Final finish shall be obtained by brooming the
surface, including the troweled edge to a gritty finish after all free moisture has disappeared from
the surface. Sprinkling of cement or sand for blotting will not be permitted.
It is the intent of this Specification to insure the highest quality of workmanship in the
construction and finishing of P.C.C. curb and gutter.
Unsightly or poorly finished surfaces will be considered grounds for rejection of the Work. The
top and/or face and gutter of the finished concrete surfaces shall be true and straight, of uniform
width and free of cracks, humps, sags, or other irregularities. The finished concrete surface shall
not vary more than two-hundredths of a foot (0.02’) from a ten foot (10’) straight edge, except
at grade changes or curves. No freestanding water is permitted on slopes at or greater than one
percent (1%). No freestanding water deeper than one-sixteenth inch (1/16”) is permitted on
slopes of less than one percent (1%). The Contractor shall flow test all new concrete curb and
gutter. Curb and gutter failing to meet this requirement will be rejected.
All defective areas shall be removed and replaced at the Contractor's expense, unless permission
to patch is granted by the Engineer. Such permission shall not be construed as an acceptance of
the Work or as a waiver of the Engineer's right to require the complete removal of the Work, if in
his opinion the patch does not satisfactorily restore the quality or appearance of the surface.
Should patching be permitted, the area shall be chipped clean to a depth of one inch (1”)
perpendicular to the surface and saturated with clean water prior to being patched. The patch
shall be made with a mortar extracted from fresh concrete by passing it through a three-eighths
inch (3/8”) screen. The mortar shall be thoroughly compacted and screeded off slightly higher
than the surrounding surface to allow for contracting or setting after the maximum shrinkage has
taken place. After one (1) to two (2) hours, the patch shall be troweled to the same finish as the
surrounding area and shall be cured as specified herein. The use of special patching material will
be permitted if approved by the Engineer.
D. Curing
Curing compounds shall be applied to all exposed surfaces immediately after finishing.
Transparent curing compounds shall contain a color dye of sufficient strength to render the film
distinctly visible on the concrete for a minimum period of four (4) hours after application.
If, at any time during the curing period any of the forms are removed, a coat of curing
compound shall be applied immediately to the exposed surface. The curing compound shall be
applied in sufficient quantity to obscure the natural color of the concrete. Additional coats shall
be applied if the Engineer determines that the coverage is not adequate. The concrete shall be
cured for the minimum period of time set forth below.
Page 42 of 103
Curb and gutter constructed of Type I/II Portland Cement Concrete must have been placed and
finished a minimum of seven (7) days prior to material being distributed against, or vibrated
(compaction) adjacent to the structure.
Curb and gutter constructed of Type III Portland Cement Concrete must have been placed and
finished a minimum of three (3) days prior to any material being distributed against, or vibrated
(compaction) adjacent to the structure.
When forms are removed before the expiration of the curing period, the edges of the concrete
shall be protected with moist earth, or sprayed with curing compound.
Other standard methods of curing the curb and gutter may be used upon approval of the
Engineer. Concrete shall not be placed unless curing compounds and necessary equipment for
applying such is on the Project site.
E. Expansion and Contraction Joints
1. Expansion Joints
Expansion joints shall be placed along all structures, as shown in the Drawings and/or
Standard Details, and around all features that project into, through, or against the
concrete. An expansion joint shall be constructed at the intersection of sidewalks;
between sidewalk crossings and sidewalks; between curbs and sidewalks (except parallel
curb); and at the beginning and end of curb returns. Additionally expansion joints shall
be constructed every fifty feet (50’) where the sidewalk span exceeds seventy-five feet
(75’) and expansion joints are not required for the above listed reasons. Expansion joint
material shall conform to the requirements of ASTM D-1751 (AASHTO M-213). Expansion
joints shall not exceed one half inch plus or minus one-eighth inch (1/2”±1/8”) in width.
Expansion joint material shall extend the full width of the structure and shall be cut to
such dimensions that the base of the expansion joint shall extend to the subgrade and
the top shall be depressed not less than one-quarter inch (1/4”) nor more than one-half
inch (1/2”) below the finished surface of the concrete. The material shall be of one (1)
piece in the vertical dimension and shall be securely fastened in a vertical position to the
existing concrete face against which fresh concrete is to be placed. After the concrete
has set, the expansion joints shall be filled flush to the finish concrete surface with an
approved polyurethane sealant applied according to the manufacturer’s recommendation.
Before sealing, the joint shall be cleaned of all dirt, gravel, concrete mortar, and other
extraneous material. Sealing shall be done in a neat workmanlike manner.
2. Contraction Joints
Transverse contraction joints, cut to a depth of one inch (1”) prior to the final set of the
concrete, shall be tooled in the sidewalks at intervals of five feet (5’), and at ten feet
(10’) intervals in the curb and gutter. Where the sidewalk adjoins the curb (parallel to it),
contraction joints in the sidewalk and curb shall be made to match where practicable.
Curb or integral curb and gutter shall be measured per linear foot along the face of the curb. Mountable
(rolled) curb and gutter shall be measured per linear foot along the gutter line. Portland Cement Concrete
(P.C.C.) Valley Gutter shall be measured as shown on the Standard Detail.

30.01, Article 1.3 - Materials. Concrete mix for sidewalks shall conform to the requirements for Class A-3.
A. Excavation and Embankment
Excavation and embankment for sidewalks shall be as described in Division 20 - Earthwork. Where
directed by the Engineer, unsuitable material in the subgrade shall be removed to a specific depth and
then backfilled with classified fill. Payment will not be allowed for excavation below grade or for backfill
materials required when such excavation is caused by negligence of the Contractor.
Embankment shall be compacted to ninety-five percent (95%) maximum density in accordance with
Division 20, Section 20.01, Article 1.5 - Compaction Standards. In areas that are inaccessible to normal
compaction equipment, approved tampers shall be used.
Before the forms are set, the subgrade shall be graded to within one inch (1”) of established grade and
the area between the sidewalk and the adjacent private property line shall be shaped to line, grade, and
section shown on the Drawings.
B. Forms and Fine Grading
Forms shall conform to requirements outlined in Section 30.02 - Portland Cement Concrete, Curb and
Gutter, and Valley Gutter. Wood forms against unexposed concrete surfaces shall be No. 2 Common
Lumber or better. Those against surfaces to be exposed shall be dressed and matched boards of uniform
thickness, and widths not exceeding ten inches (10”). Rigid, nonporous and waterproof sheet material
may be used provided the end result will be a smooth unmarked concrete surface without waves, fins or
other noticeable markings.
Plywood conforming to the requirements for form work, as set forth by the American Plywood
Association, may be used against both exposed and unexposed concrete surfaces. This plywood shall be
not less than five (5) ply and at least nine-sixteenths inch (9/16”) thick. Low areas in the subgrade shall
be backfilled with classified fill or with suitable native material as directed by the Engineer. The backfill
shall then be compacted to ninety-five percent (95%) maximum density and any dry areas in the
subgrade shall be thoroughly dampened prior to the time the concrete is placed. No payment will be
made for water, and the work of placing and cost thereof shall be considered as incidental to the
construction of the concrete sidewalk.
C. Placing and Finishing Portland Cement Concrete Sidewalk
The concrete shall be spread uniformly between the forms and thoroughly compacted with a steel shod
strikeboard. After the concrete has been thoroughly compacted and leveled, it shall be floated with wood
floats and finished at the proper time with a steel float. Joints shall be edged with a one-quarter inch
(1/4”) radius edger and the sidewalk edges shall be tooled with a one-half inch (1/2”) radius edger. After
final troweling, sidewalk on grades of less than six percent (6%) shall be given a fine hair broom finish
Page 45 of 103
applied transversely to the centerline. On grades exceeding six percent (6%), walk shall be finished by
hand with a wood float. Walk shall be re-marked as necessary after final finish to assure neat uniform
edges, joints, and score lines. Unsightly, poorly finished, and sidewalk failing to meet the requirements of
the Drawings, Specifications, and this Section will be rejected.
The sidewalk shall be divided into panels by scoring one inch (1”) deep every five feet (5’). Refer to
Section 30.02, Article 2.3, SubArticle E - Expansion and Contraction Joints for requirements for
contraction and expansion joints. The expansion joints shall be placed at all structures such as catch
basins and manholes, at driveways, and at all points of tangency and points of curvature.
Additional requirements for placing and finishing concrete in cold weather shall be as outlined in Section
30.01, Article 1.9 - Weather Limitations.
For all other exposed aggregate concrete sidewalks, Contractor shall float and trowel all surfaces to
receive the exposed aggregate finish. Seeding the surface with aggregate shall not be allowed. After the
concrete has taken its initial set, the surface aggregate shall be exposed using a water fog spray and
brooms to remove the surface matrix. The coarse surface aggregate shall be exposed very lightly,
approximately one-sixteenth inch (1/16”). After the concrete has taken its final set, a weak acid wash
shall be applied to clean and wash the exposed aggregate surfaces. The weak acid wash shall be
thoroughly neutralized and flushed from the finished surface. Under no circumstances shall Contractor
allow the acid wash to enter the storm drain lines.
Contractor shall protect adjacent construction, plantings, finishings, structures, and the public from
damage and harm due to the acid wash. The finished appearance of the exposed aggregate concrete
sidewalk shall produce an appearance and texture that matches the adjacent exposed aggregate
sidewalk. Any significant difference in texture or appearance between two adjacent concrete panels, as
determined by the Engineer, shall result in removal and replacement of concrete panels by Contractor at
no additional cost.
Contractor shall provide a two foot by two foot (2’ x 2’) exposed aggregate concrete test panel prior to
constructing the exposed aggregate concrete sidewalk. Location of the test panel will be on-site as
approved by the Engineer. Notification of providing this test panel shall be made to the Engineer no less
than 24 hours prior to making the test panels to allow the Engineer and materials analysis personnel to
be present. The Engineer may require the Contractor to provide additional panel(s) if the test panel does
not produce an appearance that matches the adjacent exposed aggregate sidewalk.
Providing the test panel and any other required test panel shall be considered incidental to the bid item
“P.C.C. Sidewalk 4” Thick (Exposed Aggregate)” and no separate payment shall be made.
D. Curing and Protection
The materials and procedures outlined in Section 30.02, Article 2.3 - Construction, shall prevail. The
curing agent shall be applied immediately after finishing and be maintained for a period of seven (7)
days. The curing agent(s) and/or concrete mixtures shall in no way deter or prevent final finishing of
concrete. The use of surface retarders may be permitted if application methods are accepted by the
Engineer, in writing, no less than twenty-four (24) hours prior to concrete placement.
The Contractor shall have readily available sufficient protective covering, such as waterproof paper or
plastic membrane, to cover the pour of an entire day in event of rain or other unsuitable weather.
The sidewalk shall be protected against damage or defacement of any kind until it has been accepted by
the Owner. Sidewalk which is not acceptable to the Engineer because of damage or defacement shall be
Page 46 of 103
removed and replaced at the expense of the Contractor. Additional requirements for curing in cold

equipped with adjustable scrapers to keep the drums clean and with efficient means of keeping
the drums/wheels wet to prevent mixes from sticking to the drums. Rollers/Drums shall be free
of flat areas, openings or projections which will mar the surface of the pavement.
E. Haul Trucks
Vehicles used for the transportation of hot-mix asphalt from the plant to the Project shall have
tight metal bottoms and shall be free from dust, screenings, petroleum oils, volatiles, and other
mineral spirits which may affect the mix being hauled. The truck beds shall be cleaned as often
as required, but at least once a day. After this operation the truck bed shall be elevated and
thoroughly drained; no excess solution shall be permitted.
When requested by the Engineer, trucks shall be equipped with covers of canvas, insulated
boxes, or other suitable material, and be of sufficient size and weight to protect the load from
adverse weather conditions and to maintain the required mix temperatures.
F. Truck Scales
Hot mix asphalt shall be weighed on platform scales furnished by the Contractor or on public
scales at the Contractor's expense. The scales shall be satisfactory to the Engineer and shall
comply with all State Laws governing the use of scales. The scales shall be tested and sealed by
an authorized public official, at the expense of the Contractor, as often as the Engineer may

provided by the Contractor. The sixteen foot (16’) straightedge shall be used on straight sections
and the ten foot (10’) straightedge on vertical curves or crown.
A. Weather Limitations
Asphalt concrete mixture shall not be placed when it is raining or when rain is imminent, on a
saturated surface, on an unstable/yielding roadbed, when the base material is frozen, or when
weather conditions prevent proper handling or finishing of the mixture. Asphalt concrete mixture
shall not be placed unless the surface temperature is forty-five degrees (45º) Fahrenheit or
warmer and the ambient air is at least thirty-two degrees (32º) Fahrenheit and not descending.
Air temperature shall be measured in the shade away from heat sources at the paving site.
B. Preparation of Area to be Paved
The area to be paved shall be true to line and grade, having a smooth dry, compacted surface
prior to the start of paving operations. The area to be paved shall be free from all loose asphalt
and foreign material.
Contractor shall notify the Engineer, a minimum of twenty-four (24) hours prior to paving, that
the newly constructed, rotomill planed, or existing surface, has been prepared in conformance
with the Drawings and Specifications and are ready to be paved. Engineer or his representative
shall inspect the grade through the use of string line, straightedge, levels, or any other means
necessary. Upon determining the grade that has been proposed for paving is in conformance
with the Drawings and Specifications, Engineer will provide written authorization for the
Contractor to proceed with the paving. The Contractor shall not initiate paving prior to receiving
written authorization to proceed.
The surface of the Leveling Course, when finished, shall not demonstrate any deviation in excess
of three-eighths inch in ten feet (3/8” in 10’) parallel with, and at right angles to, the centerline,
or more than five-eighths inch (5/8”) total from centerline to face of curb of the area to be
paved. Any deviation in excess of this amount shall be corrected by loosening, adding, or
removing material and reshaping and compacting to satisfy the above requirement.
Existing paved surfaces shall be cleaned of loose material by sweeping with a power broom,
supplemented by hand sweeping, if determined necessary by the Engineer.
Page 57 of 103
After rotomilling of a section of the roadway has been completed, that section shall be inspected
by the Engineer for areas of distress or failure. Areas requiring repair shall have the remaining
pavement removed, and the distressed area shall be excavated to the depth and limits directed
by the Engineer. The excavated area shall be backfilled, as directed by the Engineer, with
crushed aggregate Leveling Course material and/or Asphalt Concrete leveling course in
conformance with the Drawings and Specifications. Pavement surface irregularities, remaining
from the rotomilling effort, that extend more than three-quarters inch (3/4”) below the milling
indentations shall be pre-leveled and brought into conformance with the tolerances established in
Article 6.6 - Density and Surface Requirements. Pre-leveling shall be completed with an approved
Class D asphalt concrete in accordance with this Section and include the furnishing, hauling,
placing, and compaction of the asphalt concrete.
Contact surfaces of curbing, gutters, manholes, and other structures shall be painted with a thin,
uniform coating of asphaltic cement or approved equal material prior to the mixture being placed
against them. Butt joints on previously placed cooled pavement shall be saw cut and tack coated
prior to continuing the paving operation.
Contractor shall not pave against newly placed concrete curbing until said curbing has cured for a
minimum five (5) days. For the purpose of paving operations only, curb curing time may be
reduced to seventy-two (72) hours only upon receipt of Contractor’s written certification that
Type III Portland High-Early-Strength cement concrete was used in, properly placed, and
appropriate curing compounds were applied to the adjacent curb and gutter.
C. Preparation of Paving Asphalt
The asphalt shall be heated at the paving plant to a temperature at which it can be properly
handled through the pumping system, but at no time shall the temperature of the asphalts
exceed that recommended by the asphalt supplier or manufacturer, or be greater than three
hundred twenty-five degrees (325º) Fahrenheit or less than two hundred fifty degrees (250º)
Fahrenheit.
D. Preparation and Handling of Aggregates
The aggregate for the asphalt concrete mixture shall be heated and dried to a temperature
compatible with the mix requirements specified. The burner on the dryer shall be properly
adjusted to avoid damage to the aggregate and to avoid the presence of unburned fuel on the
aggregate. Any asphalt concrete mixture in which soot or fuel is present shall be wasted and no
payment made.
Drying operations shall reduce the aggregate moisture content so that the moisture content of
the asphalt concrete mixture, sampled at the point of acceptance for asphalt cement content,
shall be no more than one-half percent (0.5%) (by total weight of mix), as determined by ATM T25. Adequate dry storage shall be provided for the mineral filler.
Aggregates shall be stored at the plant in such a manner that the separate sizes will not become
intermixed. Cold aggregate shall be carefully fed to the plant in such proportions that surplus and
shortages in the hot bins will not cause breaks in the continuous operations.
Stockpiles and bins shall be sampled for gradation analysis, dust coating, and for other purposes,
at the option of the Engineer.
Page 58 of 103
When requested by the Engineer, the Contractor shall provide representative samples from each
of the hot bins. Samples shall be used to determine compliance with these Specifications.
1. Drying:
The aggregate shall be thoroughly dried and heated to provide a paving mix within a
tolerance specified herein. The moisture content of the heated and dried aggregate
shall not exceed one-half percent (0.5%). Dust collected during the drying operation
may be fed uniformly back into the hot aggregate prior to screening, provided a
position mechanical feed is used which will control the feedback to the quantity
specified by the
Engineer.
2. Screening:
Aggregates shall be screened into sizes that may be recombined into a gradation
meeting the requirements of the job-mix formula. Screens shall have normal
capacities slightly in excess of the production capacity of the mixer and rated capacity
of the dryer.
3. Hot Aggregate Storage:
Hot screened aggregate shall be stored in such a manner as to minimize segregation
and loss of temperature.
E. Mixing Plants and Controls
All plants shall be equipped with a positive means to govern the time of mixing. Mixing time shall
not be altered unless requested by the Engineer. Frequent gradation analysis of the hot
aggregates of the completed mix shall be made to be certain that the materials being used and
produced are within the tolerances of the job-mix formula and the specifications of the mix being
used. If the mix is found to be outside the hot-mix formula tolerances or outside the specification
limits, corrections shall be made in quantities measured from the hot bins and suitable changes
made at the cold bin feeders. It shall be the responsibility of the Contractor to furnish a finished
product in accordance with the Contract Documents. Tests conducted by the Engineer are for
quality acceptance purposes only and are not authorized for use in plant calibration. Plant
metering systems and scales shall be calibrated to the accuracy specified in AASHTO M-156.
Batch Type Plant: When the mix is produced in a batch type plant, the aggregate shall be
accurately weighed in the proper proportions to provide the batch weight.
The asphalt shall be heated to provide a material sufficiently fluid to produce a uniform coating
on every particle of aggregate within the specified mixing time. The temperature of the
aggregates and asphalt immediately prior to mixing shall be approximately that of the completed
batch. In no case shall the temperature of the asphalt and aggregate vary more than twenty-five
degrees (25º) Fahrenheit when placed in the mixing chamber.
A dry mixing period of not less than ten (10) seconds shall precede the addition of the asphalt to
the mix. Excess wet mixing shall be avoided. Wet mixing shall continue as long as is necessary to
obtain a thoroughly blended mix. The minimum percent of coated particles used to establish the
mixing time interval shall be ninety-five percent (95%) as determined by AASHTO T-195.
Continuous Type Plant: Continuous mix and drum plants shall in general be controlled in the
same manner as batch plants.
Page 59 of 103
The determination of mixing time shall be by weight method under the following
formula unless otherwise approved:
Mixing time in seconds =
Pugmill Dead Capacity in Pounds
Pugmill Output in Pounds Per Second
The weights used for computing mixing time shall be determined for the job, from tests made by
the Contractor and shall conform to the recommendations of the manufacturer. Mixing
temperature shall not exceed that recommended by the asphalt cement manufacturer without
the written approval of the Engineer. To aid in determining the proper temperature of the
completed batch, current viscosity data shall be available at the plant at all times.
F. Transportation of Mix
The dispatching of the hauling vehicles shall be so scheduled that all material delivered may be
placed and rolled in daylight. When variations in size of loads, speed of trucks, length of haul,
and conditions of trucks interfere with orderly continuous operations, the Engineer may order
suitable corrections to be made.
G. Mechanical Spreading
Contractor shall submit a Paving Plan for the Engineer’s review a minimum of five (5) working
days prior to initiating paving operations. The plan shall consist of at least the following items:
1. Paving schedule to include sequence of operations.
2. Operational details to include:
a. Plant operating capacity and target production rate. Process control
testing frequency for gradation, moisture, asphalt cement content,
and compaction.
b. Number and capacity of trucks, cycle time, and delivery rate.
c. The manufacturer and model of the paver and pick-up machine to
include information on grade followers, sensors, operating speed, and
production rate of the pavers.
d. Number, type, weight, and operating speed of rollers, including
replacement roller.
e. Location and method of constructing longitudinal and transverse
joints.
f. Construction plan for paving intersections and driveways.
3. The asphalt concrete shall be placed on the road surface at a temperature not less than two
hundred fifty degrees (250º) Fahrenheit or greater than three hundred degrees (300º)
Fahrenheit. Additionally, the maximum temperature to which the asphalt concrete is heated
shall not exceed the supplier’s recommendation. The asphalt concrete temperature shall be
measured directly behind the paver screed at the time of placement.
The asphalt concrete mixture shall be laid upon a surface approved in writing by the
Engineer, spread and struck-off and compacted to the thickness specified in the Drawings
and specifications. Asphalt pavers shall be used to distribute the asphalt concrete mixture in
lanes of such widths as to hold to a practical minimum the number of longitudinal joints
required.
Page 60 of 103
Longitudinal joints and edges shall be constructed to true line markings. Lines shall be
established parallel to the center line for the paver to follow in placing individual lanes. The paver
shall be operated and positioned to closely follow the established line. When backing trucks to
the finisher, care shall be taken not to jar the paver.
The texture of the unrolled surface shall be checked to determine its uniformity. The adjustment
of the screed, tamping, feed screws, hopper feed, etc., shall be checked frequently to assure
uniform spreading of the mix. Segregation of the material shall not be permitted. If segregation
occurs, the spreading operation shall be immediately suspended until the cause is determined
and corrected.
Any irregularities left by the paver shall be corrected by trimming directly behind the machine by
use of lutes or covered rakes. Immediately after trimming, the edges of the course shall be
thoroughly compacted by tamping. Distortion of the pavement during this operation shall be
avoided.
Edges against which additional pavement is to be placed shall be vertically formed to true line. A
lute or covered rake shall be used immediately behind the finisher, when required to obtain a
true line and vertical edge. Any irregularities in the surface of the pavement course shall be
corrected directly behind the paver. Excess material forming high spots shall be removed by a
shovel or lute. Indented areas shall be filled with hot-mix and smoothed with the back of a shovel
pulled over the surface. Fanning of material over such areas shall not be permitted.
On longitudinal joints, the paver shall be positioned so that in spreading, the material overlaps
the edge of the lane previously placed by one or two inches (1” or 2”) and is sufficiently high to
allow for compaction. The coarse aggregate in the material overlapping the joint shall all be
raked out into the cold lane as soon as possible behind the paver and broomed up and wasted.
In no case shall scattered rocks be rolled into the surface of either lane.
Asphalt concrete mixture which is contaminated or segregated will be rejected.
When multiple lifts are specified in the Contract, the final lift shall not be placed until all lower
lifts throughout that section, as defined by the Paving Plan, have been placed and accepted.
Paving shall not begin until all adjacent curb has been poured for at least seven (7) days when
Type I/II cement is used or three (3) days when Type III cement is used.
H. Hand Spreading
On areas where irregularities or unavoidable obstacles make the use of mechanical spreading and
finishing equipment impracticable, the asphalt concrete mixture shall be spread, raked, and luted
by hand tools. For such areas, the asphalt concrete mixture shall be placed to the required
compacted thickness and density.
I.
Compaction
Immediately after the asphalt mixture has been spread, struck off and surface irregularities
adjusted, it shall be thoroughly and uniformly compacted by rolling.
The surface shall be rolled when the mixture is in the proper condition and when the rolling does
not cause undue displacement, cracking, or shoving.
Page 61 of 103
Initial rolling shall be done with a steel-drum roller with the drive roll operating toward the paver,
and/or a suitable pneumatic tired roller. Initial rolling shall be completed while the bituminous
mat temperature is above two hundred twenty-five degrees (225º) Fahrenheit.
Following the initial rolling at least three coverages of the pavement shall be completed with a
pneumatic tired roller, while the mat temperature is above one hundred seventy-five degrees
(175º) Fahrenheit.
Final rolling shall be completed with a steel–drum roller and shall continue until roller marks and
further compression are not evident in the pavement and specified density has been achieved.
Unless otherwise directed, rolling shall begin at the sides and proceed longitudinally parallel to
the road center line, each trip overlapping one-half the roller width, gradually progressing to the
crown of the road. When paving in echelon or abutting a previously placed lane, the longitudinal
joint should be rolled first followed by the regular rolling procedure. On superelevated curves the
rolling shall begin at the low side and progress to the high side by overlapping of longitudinal
trips parallel to the centerline.
Any displacement occurring as result of the reversing of the direction of a roller, or from other
causes, shall be corrected at once by the use of rakes and addition of fresh mixture when
required. Care shall be exercised in rolling not to displace the line and grade of the edges of the
asphalt mixture.
To prevent adhesion of the mixture to the rollers, the wheels shall be kept properly moistened
with water or water mixed with very small quantities of detergent or other approved material.
Excess liquid will not be permitted.
Along forms, curbs, headers, walls, and other places not accessible to the rollers, the mixture
shall be thoroughly compacted with hot hand tampers, smoothing irons, or with mechanical
tampers. On depressed areas, a trench roller may be used or cleated compression strips may be
used under the roller to transmit compression to the depressed area.
Rollers or other vehicles shall not be parked or left standing on pavement that has not cooled
sufficiently to prevent indentation by wheels.
J.
Joints
The Contractor shall not construct longitudinal joints in the driving wheel paths. The Contractor
shall align the joints of the top layer of pavement to either the centerline of the road or to lane
lines. The Contractor shall offset the longitudinal joint in the top layer of pavement not more than

notes whether the Work was done before excavation or after excavation. When both usable and unusable
excavation are a part of the project, the limits of usable or unusable materials shall be clearly identified in
the cross sections, in the field book.
Page 85 of 103
A. Methods and Procedures
1. Equipment
Cross sections may be accomplished with 1) an engineers level, 2) a self compensating
surveyor's level, or 3) an electronic (laser) level, or 4) by electronic data collection and radial
survey method. Neither radial methods nor electronic leveling shall be employed without prior
approval from the Engineer. When radial methods or electronic leveling methods are used the
survey shall comply with or exceed the accuracy established in this article. Conditions under
which these methods may be used shall be discussed at the initial pre-construction meeting
with the Engineer. For radial methods see Article 2.13 - Electronic Data Collection and Radial
Surveys.
2. Procedure and Accuracy
When an engineering level, self compensating surveyor's level, or an electronic (laser) level is
used, cross sections shall be taken perpendicular to the centerline along tangents and on
radial lines along curves. A right angle prism shall be used to determine perpendiculars. The
height of the instruments (H.I.'s) shall be recorded to the nearest hundredth of a foot (0.01’).
All cross sectioning work shall be part of a closed level loop. If only one TBM is used the level
set-up shall be broken and a different instrument height obtained before closing into the same
TBM. The maximum allowable error for level loops used for cross sectioning shall be three
hundredths of a
foot (0.03’). Cross section readings shall be recorded to the nearest tenth of a foot (0.1’).
Horizontal measures shall be recorded and accurate to the nearest tenth of a foot (0.1’). Work
shall not be paid for if it does not meet the stated accuracy requirements.
3. Original Ground Measures
Cross section measures of original ground shall be taken at each fifty foot (50’) station as
indicated on the Drawings. Intermediate stations shall be measured by cross section wherever
grade breaks occur. Additional cross sections shall be taken at stations to include quantities
measurement of retaining walls, drainage structures, etc. Elevation shots for original ground
cross sections shall be taken at the centerline of construction according to the Drawings and
as a minimum, at the following points perpendicular to and on each side of the centerline:
• grade breaks
• edge of pavement
• curb and gutter
• shoulder of road
• toe of slope
• centerline of ditch
• top of bank
• all other physical features within the project limits. In areas where overbreak or slides are
anticipated, sections shall be extended out from centerline to include the anticipated disturbed
ground area.
4. After Excavation Measures
Cross sections shall be taken at the same stations as the original ground cross sections.
Elevation shall be for the bottom, sides and top of excavation at the following points on each
side and perpendicular to the centerline:
•
•
•
•
centerline

The Contractor shall notify the Engineer twenty-four (24) hours prior to conducting any survey
measurements involving pay quantities. The Contractor shall obtain approval of the excavation from the
Engineer prior to taking cross sections and shall provide the Engineer the opportunity to be present
during the survey. Pay quantity Work done without the Engineer's notification and approval, or any Work
covered up before proper remeasure is made, shall be just cause for non-payment.
Article 2.6 Slope Stakes
Slope stakes shall be required for each cross section station and at additional intervals such as points of
curvature and tangency of curves, street intersections, vertical curve intermediate stations to include the
high or low point of the curve, and at grade breaks. The stakes are to be set at points where the cut or
fill slopes intersect the surface of original ground.
Staking notes shall record the location of the slope stake in relation to the construction centerline, the
existing elevation shot at the catch point, the planned elevation that the slope stake is identifying, what
level of the design prism the catch point is identifying (i.e., top of unclassified fill, top of subbase, etc.),
the percent of slope for cut/fill, the distance to point slope staked, and the station of the slope stake.
The information to be shown on a slope stake is as follows:
• distance from the catch point to the point being staked.
• percent of slope of the cut/fill.
• amount of cut/fill.
• stake's location in reference to the centerline.
• centerline station of the slope stake written on the back of the stake.
The use of hand levels for setting slope stakes shall be limited to one turning point up or down from the
instrument to the catch point. Hand level turning points shall be clearly noted in the field book.
A reference stake shall be set for each slope stake. The reference stake shall be set a minimum of ten
feet (10’) and a maximum of fifteen feet (15’) beyond the slope stake. The reference stake shall re-state
the slope stake information in the event the slope stake is disturbed or destroyed. A hub shall be driven
flush with the ground at the reference stake and all elevations and distances referenced to the hub.
Article 2.7 Grade Stakes
A. Cut or Fill Stakes
Vertical cut/fill stakes shall be used where the design prism does not contain sloped shoulders and
ditches and a slope stake would not be needed. The cut/fill stake shall be comprised of a standard
wooden hub driven flush with ground surface and accompanied by a guard lath with the following
information written on it:
• amount of cut or fill
• distance to the point of cut/fill from the hub
• description of the cut or filled type, i.e. subgrade, top classified
• offset distance from construction centerline to the cut/fill point

• elevation of the top of hub.
Page 87 of 103
Cuts shall be given to the nearest tenth of a foot (0.1’). Elevations of the top of hubs shall be given to
the nearest hundredth of a foot (0.01’). Stakes shall be required at each fifty foot (50’) station
identified on the Drawings and at additional intervals such as points of curvature and tangency of
curves, street intersections, vertical curve intermediate stations to include the high or low point of the
curve, and at grade breaks. A record of the cut/fill, the design grade, the distance offset from
centerline, the centerline station and the type of cut/fill being staked shall be written in the survey
field book.
B. Finish Grade
Grade hubs shall be set to verify that the road prism is at the correct elevation prior to the placement
of leveling course material. Wooden hubs, painted or topped with colored whiskers, shall be set at the
top of classified fill, within two hundredths of a foot tolerance (0.02’). Stationing shall be fifty feet
(50’) on tangent and twentyfive feet (25’) on curves unless the Engineer approves otherwise. All grade
breaks, vertical curve intermediate points to include the high/low point of the curve, PC and PT of
horizontal curves, and street intersections shall be staked.
Hubs shall be established on the centerline of the road prism as a minimum where poured curb and
gutter is incorporated into the designed road prism. Otherwise, hubs shall be established at the
shoulder of the designed road prism, as well as the centerline of the road prism.
When parking aprons are staked, hubs shall be set on a fifty foot (50’) grid pattern unless approved
otherwise by the Engineer. The field book shall contain the centerline station, the design finish grade
elevation of the point staked, the elevation of the hub, and a description of the material being staked.
