40-01 INTENT OF CONTRACT. The intent of the contract is to provide for construction and completion,
in every detail, of the work described. It is further intended that the Contractor shall furnish all labor,
materials, equipment, tools, transportation, and supplies required to complete the work in accordance with the
plans, specifications, and terms of the contract.

make such alterations in the work as may be necessary or desirable to complete the work originally intended
in an acceptable manner. Unless otherwise specified herein, the Engineer shall be and is hereby authorized to

provided that the aggregate of such alterations does not change the total contract cost or the total cost of any
major contract item by more than 25 percent (total cost being based on the unitprices and estimated quantities
in the awarded contract). Alterations which do not exceed the 25 percent limitation shall not invalidate the
contract nor release the surety, and the Contractor agrees to accept payment for such alterations as if the
altered work had been a part of the original contract. These alterations which are for work within the general
scope of the contract shall be covered by "Change Orders" issued by the Engineer. Change orders for altered
work shall include extensions of contract time where, in the Engineer's opinion, such extensions are
commensurate with the amount and difficulty of added work.
Should the aggregate amount of altered work exceed the 25 percent limitation hereinbefore specified, such
excess altered work shall be covered by supplemental agreement. If the owner and the Contractor are unable
to agree on a unit adjustment for any contract item that requires a supplemental agreement, the owner reserves
the right to terminate the contract with respect to the item and make other arrangements for its completion.
All supplemental agreements shall be approved by the FAA and shall include valid wage determinations of
the U.S. Secretary of Labor when the amount of the supplemental agreement exceeds $2,000. However, if the
Contractor elects to waive the limitations on work that increases or decreases the originally awarded Contract
or any major contract item by more than 25%, the supplemental agreement shall be subject to the same U.S.
Secretary of Labor wage determination as was included in the originally awarded Contract.
All supplemental agreements shall require consent of the Contractor's surety and separate performance and
payment bonds.
40-03 OMITTED ITEMS. The Engineer may, in the owner's best interest, omit from the work any
contract item, except major contract items. Major contract items may be omitted by a supplemental
agreement. Such omission of contract items shall not invalidate any other contract provision or requirement.
Should a contract item be omitted or otherwise ordered to be non -performed, the Contractor shall be paid for
all work performed toward completion of such item prior to the date of the order to omit such item. Payment
for work performed shall be in accordance with the subsection titled PAYMENT FOR OMITTED ITEMS of
Section 90.
40-04 EXTRA WORK. Should acceptable completion of the contract require the Contractor to perform an
item of work for which no basis of payment has been provided in the original contract or previously issued
change orders or supplemental agreements, the same shall be called Extra Work. Extra work that is within the
general scope of the contract shall be covered by written change order. Change orders for such extra work
shall contain agreed unit prices for performing the change order work in accordance with the requirements
specified in the order, and shall contain any adjustment to the contract time that, in the Engineer's opinion, is
necessary for completion of such extra work.

PAGE 12 GENERAL PROVISIONS
i
50-01 AUTHORITY OF THE ENGINEER. The Engineer shall decide any and all questions which may
arise as to the quality and acceptability of materials furnished, work performed, and as to the manner of
performance and rate of progress of the work. He shall decide all questions which may arise as to the
interpretation of the specifications or plans relating to the work. The Engineer shall determine the amount
and quality of the several kinds of work performed and materials furnished which are to be paid for the under
contract.
50-02 CONFORMITY WITH PLANS AND SPECIFICATIONS. All work and all materials furnished
shall be in reasonably close conformity with the lines, grades, grading sections, cross sections, dimensions,
material requirements, and testing requirements that are specified (including specified tolerances) in the
contract, plans or specifications.
If the Engineer finds the materials furnished, work performed, or the finished product not within reasonably
close conformity with the plans and specifications but that the portion of the work affected will, in his/her
opinion, result in a finished product having a level of safety, economy, durability, and workmanship
acceptable to the owner, he will advise the owner of his/her determination that the affected work be accepted
and remain in place. In this event, the Engineer will document his/her determination and recommend to the
owner a basis of acceptance which will provide for an adjustment in the contract price for the affected portion
of the work. The Engineer's determination and recommended contract price adjustments will be based on
good engineering judgment and such tests or retests of the affected work as are, in his/her opinion, needed.
Changes in the contract price shall be covered by contract modifications (change order or supplemental
agreement) as applicable.
If the Engineer finds the materials furnished, work performed, or the finished product are not in reasonably
close conformity with the plans and specifications and have resulted in an unacceptable finished product, the
affected work or materials shall be removed and replaced or otherwise corrected by and at the expense of the
Contractor in accordance with the Engineer's written orders.
For the purpose of this subsection, the term "reasonably close conformity" shall not be construed as waiving
the Contractor's responsibility to complete the work in accordance with the contract, plans, and
specifications. The term shall not be construed as waiving the Engineer's right to insist on strict compliance
with the requirements of the contract, plans, and specifications during the Contractor's prosecution of the
work, when, in the Engineer's opinion, such compliance is essential to provide an acceptable finished portion
of the work.
For the purpose of this subsection, the term "reasonably close conformity" is also intended to provide the
Engineer with the authority to use good engineering judgment in his/her determinations as to acceptance of
work that is not in strict conformity but will provide a finished product equal to or better than that intended by
the requirements of the contract, plans and specifications.
The Engineer will not be responsible for the Contractor's means, methods, techniques, sequences, or
procedures of construction or the safety precautions incident thereto.
50-03 COORDINATION OF CONTRACT, PLANS, AND SPECIFICATIONS. The contract, plans,
specifications, and all referenced standards cited are essential parts of the contract requirements. A
requirement occurring in one is as binding as though occurring in all. They are intended to be complementary
and to describe and provide for a complete work. In case of discrepancy, calculated dimensions will govern
over scaled dimensions; contract technical specifications shall govern over contract general provisions, plans,
GENERAL PROVISIONS PAGE 13
cited standards for materials or testing, and cited FAA advisory circulars; contract general provisions shall
govern over plans, cited standards for materials or testing, and cited FAA advisory circulars; plans shall
govern over cited standards for materials or testing and cited FAA advisory circulars.
The Contractor shall not take advantage of any apparent error or omission on the plans or specifications. In
the event the Contractor discovers any apparent error or discrepancy, he shall immediately call upon the
Engineer for his/her interpretation and decision, and such decision shall be final.
50-04 COOPERATION OF CONTRACTOR. The Contractor will be supplied with five copies each of
the plans and specifications. He shall have available on the work at all times one copy each of the plans and
specifications. Additional copies of plans and specifications may be obtained by the Contractor for the cost of
reproduction.
The Contractor shall give constant attention to the work to facilitate the progress thereof, and he shall
cooperate with the Engineer and his/her inspectors and with other contractors in every way possible. The
Contractor shall have a competent superintendent on the work at all times who is fully authorized as his/her
agent on the work. The superintendent shall be capable of reading and thoroughly understanding the plans
and specifications and shall receive and fulfill instructions from the Engineer or his/her authorized
representative.
50-05 COOPERATION BETWEEN CONTRACTORS. The owner reserves the right to contract for and
perform other or additional work on or near the work covered by this contract.
When separate contracts are let within the limits of any one project, each Contractor shall conduct his/her
work so as not to interfere with or hinder the progress of completion of the work being performed by other
Contractors. Contractors working on the same project shall cooperate with each other as directed.
Each Contractor involved shall assume all liability, financial or otherwise, in connection with his/her contract
and shall protect and save harmless the owner from any and all damages or claims that may arise because of
inconvenience, delays, or loss experienced by him because of the presence and operations of other
Contractors working within the limits of the same project.
The Contractor shall arrange his/her work and shall place and dispose of the materials being used so as not to
interfere with the operations of the other Contractors within the limits of the same project. He shall join
his/her work with that of the others in an acceptable manner and shall perform it in proper sequence to that of
the others.
50-06 CONSTRUCTION LAYOUT AND STAKES. The Engineer shall establish horizontal and vertical
control only. The Contractor must establish all layout required for the construction of the work. Such stakes
and markings as the Engineer may set for either his/her own or the Contractor's guidance shall be preserved
by the Contractor. In case of negligence on the part of the Contractor, or his/her employees, resulting in the
destruction of such stakes or markings, an amount equal to the cost of replacing the same may be deducted
from subsequent estimates due the Contractor at the discretion of the Engineer.
The Contractor shall furnish all lines, grades and measurements from the control points necessary for the
proper prosecution and control of the work contracted for under these specifications.
The Contractor shall furnish weekly copies of the survey notes to the Engineer. The Engineer may make
periodic checks of the grades and alignments set by the Contractor. In case of error on the part of the

GENERAL PROVISIONS PAGE 15
50-08 AUTHORITY AND DUTIES OF INSPECTORS. Inspectors employed by the owner shall be
authorized to inspect all work done and all material furnished. Such inspection may extend to all or any part
of the work and to the preparation, fabrication, or manufacture of the materials to be used. Inspectors are not
authorized to revoke, alter, or waive any provision of the contract. Inspectors are not authorized to issue
instructions contrary to the plans and specifications or to act as foreman for the Contractor.
Inspectors employed by the owner are authorized to notify the Contractor or his/her representatives of any
failure of the work or materials to conform to the requirements of the contract, plans, or specifications and to
reject such nonconforming materials in question until such issues can be referred to the Engineer for his/her
decision.
50-09 INSPECTION OF THE WORK. All materials and each part or detail of the work shall be subject
to inspection by the Engineer. The Engineer shall be allowed access to all parts of the work and shall be
furnished with such information and assistance by the Contractor as is required to make a complete and
detailed inspection.
If the Engineer requests it, the Contractor, at any time before acceptance of the work, shall remove or uncover
such portions of the finished work as may be directed. After examination, the Contractor shall restore said
portions of the work to the standard required by the specifications. Should the work thus exposed or
examined prove acceptable, the uncovering, or removing, and the replacing of the covering or making good of
the parts removed will be paid for as extra work; but should the work so exposed or examined prove
unacceptable, the uncovering, or removing, and the replacing of the covering or making good of the parts
removed will be at the Contractor's expense.
Any work done or materials used without supervision or inspection by an authorized representative of the
owner may be ordered removed and replaced at the Contractor's expense unless the owner's representative
failed to inspect after having been given reasonable notice in writing that the work was to be performed.
Should the contract work include relocation, adjustment, or any other modification to existing facilities, not
the property of the (contract) owner, authorized representatives of the owners of such facilities shall have the
right to inspect such work. Such inspection shall in no sense make any facility owner a party to the contract,
and shall in no way interfere with the rights of the parties to this contract.

unit prices bid on the various contract items, and the Contractor will not be paid an additional amount for such
work.
50-13 FAILURE TO MAINTAIN THE WORK. Should the Contractor at any time fail to maintain the
work as provided in the subsection titled MAINTENANCE DURING CONSTRUCTION of this section, the
Engineer shall immediately notify the Contractor of such noncompliance. Such notification shall specify a
reasonable time within which the Contractor shall be required to remedy such unsatisfactory maintenance
condition. The time specified will give due consideration to the exigency that exists.
Should the Contractor fail to respond to the Engineer's notification, the Owner may suspend any work
necessary for the owner to correct such unsatisfactory maintenance condition, depending on the exigency that
exists. Any maintenance cost incurred by the owner, shall be deducted from monies due or to become due the
Contractor.
50-14 PARTIAL ACCEPTANCE. If at any time during the prosecution of the project the Contractor
substantially completes a usable unit or portion of the work, the occupancy of which will benefit the owner,
he may request the Engineer to make final inspection of that unit. If the Engineer finds upon inspection that
the unit has been satisfactorily completed in compliance with the contract, he may accept it as being
completed, and the Contractor may be relieved of further responsibility for that unit. Such partial acceptance
and beneficial occupancy by the owner shall not void or alter any provision of the contract.
50-15 FINAL ACCEPTANCE. Upon due notice from the Contractor of presumptive completion of the
entire project, the Engineer and owner will make an inspection. If all construction provided for and
contemplated by the contract is found to be completed in accordance with the contract, plans, and
specifications, such inspection shall constitute the final inspection. The Engineer shall notify the Contractor
in writing of final acceptance as of the date of the final inspection.
If, however, the inspection discloses any work, in whole or in part, as being unsatisfactory, the Engineer will
give the Contractor the necessary instructions for correction of same and the Contractor shall immediately
comply with and execute such instructions. Upon correction of the work, another inspection will be made
RAL PROVISIONS ,
which shall constitute the final inspection, provided the work has been satisfactorily completed. In such
event, the Engineer will make the final acceptance and notify the Contractor in writing of this acceptance as
of the date of final inspection.
50-16 CLAIMS FOR ADJUSTMENT AND DISPUTES. If for any reason the Contractor deems that
additional compensation is due him for work or materials not clearly provided for in the contract, plans, or
specifications or previously authorized as extra work, he shall notify the Engineer in writing of his/her
intention to claim such additional compensation before he begins the work on which he bases the claim. If
such notification is not given or the Engineer is not afforded proper opportunity by the Contractor for keeping
strict account of actual cost as required, then the Contractor hereby agrees to waive any claim for such
additional compensation. Such notice by the Contractor and the fact that the Engineer has kept account of the
cost of the work shall not in any way be construed as proving or substantiating the validity of the claim.
When the work on which the claim for additional compensation is
based has been completed, the Contractor shall, within ten calendar days, submit his/her written claim to the
Engineer who will present it to the owner for consideration in accordance with local laws or ordinances.
Nothing in this subsection shall be construed as a waiver of the Contractor's right to dispute final payment
based on differences in measurements or computations.
50-17 GUARANTY OF MATERIALS, EQUIPMENT AND WORK. The Contractor shall guarantee all
materials, equipment furnished, and work performed for a period of one year from the date of

FAA or NOAA, or a utility service of another government agency that may be authorized by the owner to
construct, reconstruct or maintain such utility services or facilities during the progress of the work. In
addition, the Contractor shall control his/her operations to prevent the unscheduled interruption of such utility
services and facilities.
To the extent that such public or private utility services, FAA, or NOAA facilities, or utility services of
another governmental agency are known to exist within the limits of the contract work, the approximate
locations have been indicated on the plans and the owners are indicated on the plans.
It is understood and agreed that the owner does not guarantee the accuracy or the completeness of the location
information relating to existing utility services, facilities, or structures that may be shown on the plans or
encountered in the work. Any inaccuracy or omission in such information shall not relieve the Contractor of
his/her responsibility to protect such existing features from damage or unscheduled interruption of service.
It is further understood and agreed that the Contractor shall, upon execution of the contract, notify the owners
of all utility services or other facilities of his/her plan of operations. Such notification shall be in writing
addressed to THE PERSON TO CONTACT as provided hereinbefore in this subsection and the subsection
titled RESTORATION OF SURFACES DISTURBED BY OTHERS of this section. A copy of each
notification shall be given to the Engineer.
In addition to the general written notification hereinbefore provided, it shall be the responsibility of the
Contractor to keep such individual owners advised of changes in his/her plan of operations that would affect
such owners.
Prior to commencing the work in the general vicinity of an existing utility service or facility, the Contractor
shall again notify each such owner of his/her plan of operation. If, in the Contractor's opinion, the owner's
assistance is needed to locate the utility service or facility or the presence of a representative of the owner is
desirable to observe the work, such advice should be included in the notification. Such notification shall be
given by the most expeditious means to reach the utility owner's PERSON TO CONTACT no later than two
normal business days prior to the Contractor's commencement of operations in such general vicinity. The
Contractor shall furnish a written summary of the notification to the Engineer.
The Contractor's failure to give the two day's notice hereinabove provided shall be cause for the Owner to
suspend the Contractor's operations in the general vicinity of a utility service or facility.
Where the outside limits of an underground utility service have been located and staked on the ground, the
Contractor shall be required to use excavation methods acceptable to the Engineer within 3 feet (90 cm) of
such outside limits at such points as may be required to ensure protection from damage due to the Contractor's
operations.
Should the Contractor damage or interrupt the operation of a utility service or facility by accident or
otherwise, he shall immediately notify the proper authority and the Engineer and shall take all reasonable
measures to prevent further damage or interruption of service. The Contractor, in such events, shall cooperate
with the utility service or facility owner and the Engineer continuously until such damage has been repaired
and service restored to the satisfaction of the utility or facility owner.
The Contractor shall bear all costs of damage and restoration of service to any utility service or facility due to
his/her operations whether or not due to negligence or accident. The contract owner reserves the right to
deduct such costs from any monies due or which may become due the Contractor, or his/her surety.
70-16 FURNISHING RIGHTS -OF -WAY. The owner will be responsible for furnishing all rights -of -way
upon which the work is to be constructed in advance of the Contractor's operations.
70-17 PERSONAL LIABILITY OF PUBLIC OFFICIALS. In carrying out any of the contract
provisions or in exercising any power or authority granted to him by this contract, there shall be no liability
upon the Engineer, his/her authorized representatives, or any officials of the owner either personally or as an
official of the owner. It is understood that in such matters they act solely as agents and representatives of the
owner.
70-18 NO WAIVER OF LEGAL RIGHTS. Upon completion of the work, the owner will expeditiously
make final inspection and notify the Contractor of final acceptance. Such final acceptance, however, shall not
preclude or stop the owner from correcting any measurement, estimate, or certificate made before or after
completion of the work, nor shall the owner be precluded or stopped from recovering from the Contractor or
his/her surety, or both, such overpayment as may be sustained, or by failure on the part of the Contractor to
fulfill his/her obligations under the contract. A waiver on the part of the owner of any breach of any part of
the contract shall not be held to be a waiver of any other or subsequent breach.
The Contractor, without prejudice to the terms of the contract, shall be liable to the owner for latent defects,
fraud, or such gross mistakes as may amount to fraud, or as regards the owner's rights under any warranty or
guaranty.
70-19 ENVIRONMENTAL PROTECTION. The Contractor shall comply with all Federal, state, and
local laws and regulations controlling pollution of the environment. He shall take necessary precautions to
prevent pollution of streams, lakes, ponds, and reservoirs with fuels, oils, bitumens, chemicals, or other
harmful materials and to prevent pollution of the atmosphere from particulate and gaseous matter.
70-20 ARCHAEOLOGICAL AND HISTORICAL FINDINGS. Unless otherwise specified in this
subsection, the Contractor is advised that the site of the work is not within any property, district, or site, and
does not contain any building, structure, or object listed in the current National Register of Historic Places
published by the United States Department of Interior.
Should the Contractor encounter, during his/her operations, any building, part of a building, structure, or
object which is incongruous with its surroundings, he shall immediately cease operations in that location and
notify the Engineer. The Engineer will immediately investigate the Contractor's finding and the Owner will
direct the Contractor to either resume his/her operations or to suspend operations as directed.
Should the Owner order suspension of the Contractor's operations in order to protect an archaeological or
historical finding, or order the Contractor to perform extra work, such shall be covered by an appropriate
contract modification (change order or supplemental agreement) as provided in the subsection titled EXTRA
WORK of Section 40 and the subsection titled PAYMENT FOR EXTRA WORK AND FORCE ACCOUNT
WORK of Section 90. If appropriate, the contract modification shall include an extension of contract time in
accordance with the subsection titled DETERMINATION AND EXTENSION OF CONTRACT TIME of
Section 80.

SECTION F
PROSECUTION AND PROGRESS
80-01 SUBLETTING OF CONTRACT. The owner will not recognize any subcontractor on the work. The
Contractor shall at all times when work is in progress be represented either in person, by a qualified
superintendent, or by other designated, qualified representative who is duly authorized to receive and execute
orders of the Engineer.
Should the Contractor elect to assign his/her contract, said assignment shall be concurred in by the surety,
shall be presented for the consideration and approval of the owner, and shall be consummated only on the
written approval of the owner. In case of approval, the Contractor shall file copies of all subcontracts with the
Engineer.
80-02 NOTICE TO PROCEED. The notice to proceed shall state the date on which it is expected the
Contractor will begin the construction and from which date contract time will be charged. The Contractor
shall begin the work to be performed under the contract within 10 days of the date set by the Engineer in the
written notice to proceed, but in any event, the Contractor shall notify the Engineer at least 24 hours in
advance of the time actual construction operations will begin.
80-03 PROSECUTION AND PROGRESS. Unless otherwise specified, the Contractor shall submit his/her
progress schedule for the Engineer's approval within 10 days after the effective date of the notice to proceed.
The Contractor's progress schedule, when approved by the Engineer, may be used to establish major
construction operations and to check on the progress of the work. The Contractor shall provide sufficient
materials, equipment, and labor to guarantee the completion of the project in accordance with the plans and
specifications within the time set forth in the proposal.
If the Contractor falls significantly behind the submitted schedule, the Contractor shall, upon the Engineer's
request, submit a revised schedule for completion of the work within the contract time and modify his/her
operations to provide such additional materials, equipment, and labor necessary to meet the revised schedule.
Should the prosecution of the work be discontinued for any reason, the Contractor shall notify the Engineer at
least 24 hours in advance of resuming operations.
For A.I.P. contracts, the Contractor shall not commence any actual construction prior to the date on which the
notice to proceed is issued by the owner.
80-04 LIMITATION OF OPERATIONS. The Contractor shall control his/her operations and the
operations of his/her subcontractors and all suppliers so as to provide for the free and unobstructed movement
of aircraft in the AIR OPERATIONS AREAS of the airport.
When the work requires the Contractor to conduct his/her operations within an AIR OPERATIONS AREA of
the airport, the work shall be coordinated with airport management (through the Engineer) at least 48 hours
prior to commencement of such work. The Contractor shall not close an AIR OPERATIONS AREA until so
authorized by the Engineer and until the necessary temporary marking and associated lighting is in place as
provided in the subsection titled BARRICADES, WARNING SIGNS, AND HAZARD MARKINGS of
Section 70.
80-05 CHARACTER OF WORKERS, METHODS, AND EQUIPMENT. The Contractor shall, at all
times, employ sufficient labor and equipment for prosecuting the work to full completion in the manner and
time required by the contract, plans, and specifications.
PAGE 30GENERAL PROVISIONS
All workers shall have sufficient skill and experience to perform properly the work assigned to them.
Workers engaged in special work or skilled work shall have sufficient experience in such work and in the
operation of the equipment required to perform the work satisfactorily.
Any person employed by the Contractor or by any subcontractor who, violates any operational regulations
and in the opinion of the Engineer, does not perform his work in a proper and skillful manner or is
intemperate or disorderly shall, at the written request of the Engineer, be removed forthwith by the Contractor
or subcontractor employing such person, and shall not be employed again in any portion of the work without
approval of the Engineer.
Should the Contractor fail to remove such persons or person, or fail to furnish suitable and sufficient
personnel for the proper prosecution of the work, the Engineer may suspend the work by written notice until
compliance with such orders.
All equipment which is proposed to be used on the work shall be of sufficient size and in such mechanical
condition as to met requirements of the work and to produce a satisfactory quality of work. Equipment used
on any portion of the work shall be such that no injury to previously completed work, adjacent property, or
existing airport facilities will result from its use.
When the methods and equipment to be used by the Contractor in accomplishing the work are not prescribed
in the contract, the Contractor is free to use any methods or equipment that will accomplish the work in
conformity with the requirements of the contract, plans, and specifications.
When the contract specifies the use of certain methods and equipment, such methods and equipment shall be
used unless others are authorized by the Engineer. If the Contractor desires to use a method or type of
equipment other than specified in the contract, he may request authority from the Engineer to do so. The
request shall be in writing and shall include a full description of the methods and equipment proposed and of
the reasons for desiring to make the change. If approval is given, it will be on the condition that the
Contractor will be fully responsible for producing work in conformity with contract requirements. If, after
trial use of the substituted methods or equipment, the Engineer determines that the work produced does not
meet contract requirements, the Contractor shall discontinue the use of the substitute method or equipment
and shall complete the remaining work with the specified methods and equipment. The Contractor shall
remove any deficient work and
replace it with work of specified quality, or take such other corrective action as the Engineer may direct. No
change will be made in basis of payment for the contract items involved nor in contract time as a result of
authorizing a change in methods or equipment under this subsection.
80-06 TEMPORARY SUSPENSION OF THE WORK. The Engineer shall have the authority to suspend
the work wholly, or in part, for such period or periods as he may deem necessary, due to unsuitable weather,
or such other conditions as are considered unfavorable for the prosecution of the work, or for such time as is
necessary due to the failure on the part of the Owner to carry out orders given or perform any or all provisions
of the contract.
In the event that the Contractor is ordered by the Owner, in writing, to suspend work for some unforeseen
cause not otherwise provided for in the contract and over which the Contractor has no control, the Contractor
may be reimbursed for actual money expended on the work during the period of shutdown. No allowance
will be made for anticipated profits. The period of shutdown shall be computed from the effective date of the
Owner's order to suspend work to the effective date of the Owner's order to resume the work. Claims for such
compensation shall be filed with the Engineer within the time period stated in the Owner's order to resume
work. The Contractor shall submit with his/her claim information substantiating the amount shown on the
claim. The Engineer will forward the Contractor's claim to the Owner for consideration in accordance with
local laws or ordinances. No provision of this article shall be construed as entitling the Contractor to
compensation for delays due to inclement weather, for suspensions made at the request of the Contractor, or
for any other delay provided for in the contract, plans, or specifications.
If it should become necessary to suspend work for an indefinite period, the Contractor shall store all materials
in such manner that they will not become an obstruction nor become damaged in any way. He shall take
every precaution to prevent damage or deterioration of the work performed and provide for normal drainage
of the work. The Contractor shall erect temporary structures where necessary to provide for traffic on, to, or
from the airport.
80-07 DETERMINATION AND EXTENSION OF CONTRACT TIME. The number of calendar or
working days allowed for completion of the work shall be stated in the proposal and contract and shall be
known as the CONTRACT TIME.
Should the contract time require extension for reasons beyond the Contractor's control, it shall be adjusted as
follows:
a. CONTRACT TIME based on WORKING DAYS shall be calculated weekly by the Engineer. The
Engineer will furnish the Contractor a copy of his/her weekly statement of the number of working days
charged against the contract time during the week and the number of working days currently specified for
completion of the contract (the original contract time plus the number of working days, if any, that have been
included in approved CHANGE ORDERS or SUPPLEMENTAL AGREEMENTS covering EXTRA
WORK).
The Engineer shall base his/her weekly statement of contract time charged on the following considerations:
(1) No time shall be charged for days on which the Contractor is unable to proceed with the principal
item of work under construction at the time for at least 6 hours with the normal work force employed
on such principal item. Should the normal work force be on a double -shift, 12 hours shall be used.
Should the normal work force be on a triple -shift, 18 hours shall apply. Conditions beyond the
Contractor's control such as strikes, lockouts, unusual delays in transportation, temporary suspension
of the principal item of work under construction or temporary suspension of the entire work which
have been ordered by the Owner for reasons not the fault of the Contractor, shall not be charged
against the contract time.
(2) The Engineer will not make charges against the contract time prior to the effective date of the
notice to proceed.
(3) The Engineer will begin charges against the contract time on the first working day after the
effective date of the notice to proceed.
(4) The Engineer will not make charges against the contract time after the date of final acceptance as
defined in the subsection titled FINAL ACCEPTANCE of Section 50.
(5) The Contractor will be allowed 1 week in which to file a written protest setting forth his/her
objections to the Engineer's weekly statement. If no objection is filed within such specified time, the
weekly statement shall be considered as acceptable to the Contractor.
The contract time (stated in the proposal) is based on the originally estimated quantities as described in the
subsection titled INTERPRETATION OF ESTIMATED PROPOSAL QUANTITIES of Section 20. Should
the satisfactory completion of the contract require performance of work in greater quantities than those
estimated in the proposal, the contract time shall be increased in the same proportion as the cost of the
., 32 GENERAL PROVISIONS
actually completed quantities bears to the cost of the originally estimated quantities in the proposal. Such
increase in contract time shall not consider either the cost of work or the extension of contract time that has
been covered by change order or supplemental agreement and shall be made at the time of final payment.
b. CONTRACT TIME based on CALENDAR DAYS shall consist of the number of calendar days stated in
the contract counting from the effective date of the notice to proceed and including all Saturdays, Sundays,
holidays, and nonwork days. All calendar days elapsing between the effective dates of the Owner's orders to
suspend and resume all work, due to causes not the fault of the Contractor, shall be excluded.
At the time of final payment, the contract time shall be increased in the same proportion as the cost of the
actually completed quantities bears to the cost of the originally estimated quantities in the proposal. Such
increase in the contract time shall not consider either cost of work or the extension of contract time that has
been covered by a change order or supplemental agreement. Charges against the contract time will cease as
of the date of final acceptance.
c. When the contract time is a specified completion date, it shall be the date on which all contract work shall
be substantially completed.
If the Contractor finds it impossible for reasons beyond his/her control to complete the work within the
contract time as specified, or as extended in accordance with the provisions of this subsection, he may, at any
time prior to the expiration of the contract time as extended, make a written request to the Engineer for an
extension of time setting forth the reasons which he believes will justify the granting of his/her request. The
Contractor's plea that insufficient time was specified is not a valid reason for extension of time. If the
Engineer finds that the work was delayed because of conditions beyond the control and without the fault of
the Contractor, he may extend the time for completion in such amount as the conditions justify. The extended
time for completion shall then be in full force and effect, the same as though it were the original time for
completion.
80-08 FAILURE TO COMPLETE ON TIME. For each calendar day or working day, as specified in the
contract, that any work remains uncompleted after the contract time (including all extensions and adjustments
as provided in the subsection titled DETERMINATION AND EXTENSION OF CONTRACT TIME of this
Section) the sum specified in the contract and proposal as liquidated damages will be deducted from any
money due or to become due the Contractor or his/her surety. Such deducted sums shall not be deducted as a
penalty but shall be considered as liquidation of a reasonable portion of damages including but not limited to
additional engineering services, that will be incurred by the owner should the Contractor fail to complete the
work in the time provided in his/her contract.
Permitting the Contractor to continue and finish the work or any part of it after the time fixed for its
completion, or after the date to which the time for completion may have been extended, will in no way
operate as a wavier on the part of the owner of any of its rights under the contract.
80-09 DEFAULT AND TERMINATION OF CONTRACT. The Contractor shall be considered in default
of his/her contract and such default will be considered as cause for the owner to terminate the contract for any
of the following reasons if the Contractor:
a. Fails to begin the work under the contract within the time specified in the "Notice to Proceed," or
b. Fails to perform the work or fails to provide sufficient workers, equipment or materials to assure
completion of work in accordance with the terms of the contract, or
e. Performs the work unsuitably or neglects or refuses to remove materials or to perform anew such
work as may be rejected as unacceptable and unsuitable, or
PROVISIONSGENERAL PAGE 33
d. Discontinues the prosecution of the work, or
e. Fails to resume work which has been discontinued within a reasonable time after notice to do so, or
L Becomes insolvent or is declared bankrupt, or commits any act of bankruptcy or insolvency, or
g. Allows any final judgment to stand against him unsatisfied for a period of 10 days, or
h. Makes an assignment for the benefit of creditors, or
i. For any other cause whatsoever, fails to carry on the work in an acceptable manner.
Should the Engineer consider the Contractor in default of the contract for any reason hereinbefore, he shall
immediately give written notice to the Contractor and the Contractor's surety as to the reasons for considering
the Contractor in default and the owner's intentions to terminate the contract.
If the Contractor or surety, within a period of 10 days after such notice, does not proceed in accordance
therewith, then the owner will, upon written notification from the Engineer of the facts of such delay, neglect,
or default and the Contractor's failure to comply with such notice, have full power and authority without
violating the contract, to take the prosecution of the work out of the hands of the Contractor. The owner may
appropriate or use any or all materials and equipment that have been mobilized for use in the work and are
acceptable and may enter into an agreement for the completion of said contract according to the terms and
provisions thereof, or use such other methods as in the opinion of the Engineer will be required for the
completion of said contract in an acceptable manner.
All costs and charges incurred by the owner, together with the cost of completing the work under contract,
will be deducted from any monies due or which may become due the Contractor. If such expense exceeds the
sum which would have been payable under the contract, then the Contractor and the surety shall be liable and
shall pay to the owner the amount of such excess.
80-10 TERMINATION FOR NATIONAL, EMERGENCIES. The owner shall terminate the contract or
portion thereof by written notice when the Contractor is prevented from proceeding with the construction
contract as a direct result of an Executive Order of the President with respect to the prosecution of war or in

SECTION 90
MEASUREMENT AND PAYMENT
90-01 MEASUREMENT OF QUANTITIES. All work completed under the contract will be measured by
the Engineer, or his/her authorized representatives, using United States Customary Units of Measurement or
the International System of Units.
The method of measurement and computations to be used in determination of quantities of material furnished
and of work performed under the contract will be those methods generally recognized as conforming to good
engineering practice.
Unless otherwise specified, longitudinal measurements for area computations will be made horizontally, and
no deductions will be made for individual fixtures (or leave -outs) having an area of 9 square feet (0.8 square
meter) or less. Unless otherwise specified, transverse measurements for area computations will be the neat
dimensions shown on the plans or ordered in writing by the Engineer.
Structures will be measured according to neat lines shown on the plans or as altered to fit field conditions.
Unless otherwise specified, all contract items which are measured by the linear foot such as electrical ducts,
conduits, pipe culverts, underdrains, and similar items shall be measured parallel to the base or foundation
upon which such items are placed.
In computing volumes of excavation the average end area method or other acceptable methods will be used.
The thickness of plates and galvanized sheet used in the manufacture of corrugated metal pipe, metal plate
pipe culverts and arches, and metal cribbing will be specified and measured in decimal fraction of inches.
The term "ton" will mean the short ton consisting of 2,000 pounds (907 kilograms) avoirdupois. All materials
which are measured or proportioned by weights shall be weighed on accurate, approved scales by competent,
qualified personnel at locations designed by the Engineer. If material is shipped by rail, the car weight may
be accepted provided that only the actual weight of material be paid for. However, car weights will not be
acceptable for material to be passed through mixing plants. Trucks used to haul material being paid for by
weight shall be weighed empty daily at such times as the Engineer directs, and each truck shall bear a plainly
legible identification mark.
Materials to be measured by volume in the hauling vehicle shall be hauled in approved vehicles and measured
therein at the point of
delivery. Vehicles for this purpose may be of any size or type acceptable to the Engineer, provided that the
body is of such shape that the actual contents may be readily and accurately determined. All vehicles shall be
loaded to at least their water level capacity, and all loads shall be leveled when the vehicles arrive at the point
of delivery.
When requested by the Contractor and approved by the Engineer in writing, material specified to be measured
by the cubic yard (cubic meter) may be weighed, and such weights will be converted to cubic yards (cubic
meters) for payment purposes. Factors for conversion from weight measurement to volume measurement will
be determined by the Engineer and shall be agreed to by the Contractor before such method of measurement
of pay quantities is used.
Bituminous materials will be measured by the gallon (liter) or ton (kilogram). When measured by volume,
such volumes will be measured at 60T (15°C) or will be corrected to the volume at 60T (15°C)
using ASTM D 1250 for asphalts or ASTM D 633 for tars.
PAGE 36 GENERAL PROVISIONS
Net certified scale weights or weights based on certified volumes in the case of rail shipments will be used as
a basis of measurement, subject to correction when bituminous material has been lost from the car or the
distributor, wasted, or otherwise not incorporated in the work.
When bituminous materials are shipped by truck or transport, net certified weights by volume, subject to
correction for loss or foaming, may be used for computing quantities.
Cement will be measured by the ton (kilogram) or hundredweight (kilogram).
Timber will be measured by the thousand feet board measure (M.F.B.M.) actually incorporated in the
structure. Measurement will be based on nominal widths and thicknesses and the extreme length of each
piece.
The term "lump sum" when used as an item of payment will mean complete payment for the work described
in the contract.
When a complete structure or structural unit (in effect, "lump sum" work) is specified as the unit of
measurement, the unit will be construed to include all necessary fittings and accessories.
Rental of equipment will be measured by time in hours of actual working time and necessary traveling time of
the equipment within the limits of the work. Special equipment ordered by the Engineer in connection with
force account work will be measured as agreed in the change order or supplemental agreement authorizing
such force account work as provided in the subsection titled PAYMENT FOR EXTRA AND FORCE
ACCOUNT WORK of this section.
When standard manufactured items are specified such as fence, wire, plates, rolled shapes, pipe conduit, etc.,
and these items are identified by gage, unit weight, section dimensions, etc., such identification will be
considered to be nominal weights or dimensions. Unless more stringently controlled by tolerances in cited
specifications, manufacturing tolerances established by the industries involved will be accepted.
Scales for weighing materials which are required to be proportioned or measured and paid for by weight shall
be famished, erected, and maintained.by the Contractor, or be certified permanently installed commercial
scales.
Scales shall be accurate within one-half percent of the correct weight throughout the range of use. The
Contractor shall have the scales checked under the observation of the inspector before beginning work and at
such other times as requested. The intervals shall be uniform in spacing throughout the graduated or marked
length of the beam or dial and shall not exceed one -tenth of 1 percent of the nominal rated capacity of the
scale, but not less than 1 pound (454 grams). The use of spring balances will not be permitted.
Beams, dials, platforms, and other scale equipment shall be so arranged that the operator and the inspector can
safely and conveniently view them.
Scale installations shall have available ten standard 50-pound (2.3 kilogram) weights for testing the weighing
equipment or suitable weights and devices for other approved equipment.
Scales must be tested for accuracy and serviced before use at a new site. Platform scales shall be installed and
maintained with the platform level and rigid bulkheads at each end.
Scales "overweighing" (indicating more than correct weight) will not be permitted to operate, and all
materials received subsequent to the last previous correct weighing -accuracy test will be reduced by the
GENERAL PROVISIONS PAGE 37
percentage of error in excess of one-half of 1 percent.
In the event inspection reveals the scales have been "underweighing" (indicating less than correct weight),
they shall be adjusted, and no additional payment to the Contractor will be allowed for materials previously
weighed and recorded.
All costs in connection with furnishing, installing, certifying, testing, and maintaining scales; for furnishing
check weights and scale house; and for all other items specified in this subsection, for the weighing of
materials for proportioning or payment, shall be included in the unit contract prices for the various items of
the project.
When the estimated quantities for a specific portion of the work are designated as the pay quantities in the
contract, they shall be the final quantities for which payment for such specific portion of the work will be
made, unless the dimensions of said portions of the work shown on the plans are revised by the Engineer. If
revised dimensions result in an increase or decrease in the quantities of such work, the final quantities for
payment will be revised in the amount represented by the authorized changes in the dimensions.
90-02 SCOPE OF PAYMENT. The Contractor shall receive and accept compensation provided for in the
contract as full payment for furnishing all materials, for performing all work under the contract in a complete
and acceptable manner, and for all risk, loss, damage, or expense of whatever character arising out of the
nature of the work or the prosecution thereof, subject to the provisions of the subsection titled NO WAIVER
OF LEGAL RIGHTS of Section 70.
When the "basis of payment" subsection of a technical specification requires that the contract price (price bid)
include compensation for certain work or material essential to the item, this same work or material will not
also be measured for payment under any other contract item which may appear elsewhere in the contract,
plans, or specifications.
90-03 COMPENSATION FOR ALTERED QUANTITIES. When the accepted quantities of work vary
from the quantities in the proposal, the Contractor shall accept as payment in full, so far as contract items are
concerned, payment at the original contract price for the accepted quantities of work actually completed and
accepted. No allowance, except as provided for in the subsection titled ALTERATION OF WORK AND
QUANTITIES of Section 40 will be made for any increased expense, loss of expected reimbursement, or loss
of anticipated profits suffered or claimed by the Contractor which results directly from such alterations or
indirectly from his/her unbalanced allocation of overhead and profit among the contract items, or from any
other cause.
90-04 PAYMENT FOR OMITTED ITEMS. As specified in the subsection titled OMITTED ITEMS of
Section 40, the Engineer shall have the right to omit from the work (order nonperformance) any contract item,
except major contract items, in the best interest of the owner.
Should the Engineer omit or order nonperformance of a contract item or portion of such item from the work,
the Contractor shall accept payment in full at the contract prices for any work actually completed and
acceptable prior to the Engineer's order to omit or non -perform such contract item.
Acceptable materials ordered by the Contractor or delivered on the work prior to the date of the Engineer's
order will be paid for at the actual cost to the Contractor and shall thereupon become the property of the
owner.
In addition to the reimbursement hereinbefore provided, the Contractor shall be reimbursed for all actual costs
incurred for the purpose of performing the omitted contract item prior to the date of the Engineer's order.
Such additional costs incurred by the Contractor must be directly related to the deleted contract item and shall
PAGE 38 GENERAL PROVISIOW
be supported by certified statements by the Contractor as to the nature the amount of such costs.
90-05 PAYMENT FOR EXTRA AND FORCE ACCOUNT WORK. Extra work, performed in
accordance with the subsection titled EXTRA WORK of Section 40, will be paid for at the contract prices or
agreed prices specified in the change order or supplemental agreement authorizing the extra work. When the
change order or supplemental agreement authorizing the extra work requires that it be done by force account,
such force account shall be measured and paid for based on expended labor, equipment, and materials plus a
negotiated and agreed upon allowance for overhead and profit.
a. Miscellaneous. No additional allowance will be made for general superintendence, the use of small
tools, or other costs for which no specific allowance is herein provided.
b. Comparison of Record. The Contractor and the Engineer shall compare records of the cost of
force account work at the end of each day. Agreement shall be indicated by signature of the
Contractor and the Engineer or their duly authorized representatives.
c. Statement. No payment will be made for work performed on a force account basis until the
Contractor has furnished the Engineer with duplicate itemized statements of the cost of such force
account work detailed as follows:

for such work but are taken from the Contractor's stock, then in lieu of the invoices the Contractor shall
furnish an affidavit certifying that such materials were taken from his/her stock, that the quantity claimed was
actually used, and that the price and transportation claimed represent the actual cost to the Contractor.
90-06 PARTIAL PAYMENTS. Partial payments will be made at least once each month as the work
progresses. Said payments will be based upon estimates prepared by the Engineer of the value of the work
performed and materials complete in place in accordance with the contract, plans, and specifications. Such
partial payments may also include the delivered actual cost of those materials stockpiled and stored in
accordance with the subsection titled PAYMENT FOR MATERIALS ON HAND of this section.
No partial payment will be made when the amount due the Contractor since the last estimate amounts to less
than five hundred dollars.
From the total of the amount determined to be payable on a partial payment, 10 percent of such total amount
will be deducted and retained by the owner until the final payment is made, except as may be provided (at the
GENERAL PROVISIONS PAGE 39
Contractor's option) in the subsection titled PAYMENT OF WITHHELD FUNDS of this section. The balance
(90 percent) of the amount payable, less all previous payments, shall be certified for payment. Should the
Contractor exercise his/her option, as provided in the subsection titled PAYMENT OF WITHHELD FUNDS
of this section, no such 10 percent retainage shall be deducted.
When not less than 95 percent of the work has been completed the Engineer may, at the Owner's discretion
and with the consent of the surety, prepare an estimate from which will be retained an amount not less than
twice the contract value or estimated cost, whichever is greater, of the work remaining to be done. The
remainder, less all previous payments and deductions, will then be certified for payment to the Contractor.
It is understood and agreed that the Contractor shall not be entitled to demand or receive partial payment
based on quantities of work in excess of those provided in the proposal or covered by approved change orders
or supplemental agreements, except when such excess quantities have been determined by the Engineer to be
a part of the final quantity for the item of work in question.
No partial payment shall bind the owner to the acceptance of any materials or work in place as to quality or
quantity. All partial payments are subject to correction at the time of final payment as provided in the
subsection titled ACCEPTANCE AND FINAL PAYMENT of this section.
The contractor shall deliver to the Owner a complete release of all claims for labor and material arising
out of this contract before the final retained percentage or final payment is made. If any subcontractor
or supplier fails to furnish such a release in full, the Contractor may furnish a bond or other collateral
satisfactory to the Owner to indemnify the Owner against any potential lien or other such claim The
bond or collateral shall include all costs, expenses, and attorney fees the Owner may be compelled to
pay in discharging any such lien or claim.
90-07 PAYMENT FOR MATERIALS ON HAND. Partial payments may be made to the extent of the
delivered cost of materials to be incorporated in the work, provided that such materials meet the requirements
of the contract, plans, and specifications and are delivered to acceptable sites on the airport property or at
other sites in the vicinity that are acceptable to the owner. Such delivered costs of stored or stockpiled
materials may be included in the next partial payment after the following conditions are met:
a. The material has been stored or stockpiled in a manner acceptable to the Engineer at or on an
approved site.
b. The Contractor has furnished the Engineer with acceptable evidence of the quantity and quality of
such stored or stockpiled materials.

material so stored or stockpiled.
e. The Contractor has furnished the owner evidence that the material so stored or stockpiled is insured
against loss by damage to or disappearance of such materials at anytime prior to use in the work.
It is understood and agreed that the transfer of title and the owner's payment for such stored or stockpiled
materials shall in no way relieve the Contractor of his/her responsibility for furnishing and placing such
materials in accordance with the requirements of the contract, plans, and specifications.
PAGE 40 G EliV
In no case will the amount of partial payments for materials on hand exceed the contract price for such
materials or the contract price for the contract item in which the material is intended to be used.
No partial payment will be made for stored or stockpiled living or perishable plant materials.
The Contractor shall bear all costs associated with the partial payment of stored or stockpiled materials in
accordance with the provisions of this subsection.
90-08 PAYMENT OF WITHHELD FUNDS. At the Contractor's option, he/she may request that the owner
accept (in lieu of the 10 percent retainage on partial payments described in the subsection titled PARTIAL
PAYMENTS of this section) the Contractor's deposits in escrow under the following conditions.
a. The Contractor shall bear all expenses of establishing and maintaining an escrow account and
escrow agreement acceptable to the owner.
b. The Contractor shall deposit to and maintain in such escrow only those securities or bank
certificates of deposit as are acceptable to the owner and having a value not less than the 10 percent
retainage that would otherwise be withheld from partial payment.
c. The Contractor shall enter into an escrow agreement satisfactory to the owner.
d. The Contractor shall obtain the written consent of the surety to such agreement.
90-09 ACCEPTANCE AND FINAL PAYMENT. When the contract work has been accepted in
accordance with the requirements of the subsection titled FINAL ACCEPTANCE of Section 50, the Engineer
will prepare the final estimate of the items of work actually performed. The Contractor shall approve the
Engineer's final estimate or advise the Engineer of his/her objections to the final estimate which are based on
disputes in measurements or computations of the final quantities to be paid under the contract as amended by
change order or supplemental agreement. The Contractor and the Engineer shall resolve all disputes (if any)
in the measurement and computation of final quantities to be paid within 30 calendar days of the Contractor's
receipt of the Engineer's final estimate. If, after such 30-day period, a dispute still exists, the Contractor may
approve the Engineer's estimate under protest of the quantities in dispute, and such disputed quantities shall be
considered by the owner as a claim in accordance with the subsection titled CLAIMS FOR ADJUSTMENT
AND DISPUTES of Section 50.
After the Contractor has approved, or approved under protest, the Engineer's final estimate, final payment will
be processed based on the entire sum, or the undisputed sum in case of approval under protest, determined to
be due the Contractor less all previous payments and all amounts to be deducted under the provisions of the
contract. All prior partial estimates and payments shall be subject to correction in the final estimate and
payment.
If the Contractor has filed a claim for additional compensation under the provisions of the subsection titled
CLAIMS FOR ADJUSTMENTS AND DISPUTES of Section 50 or under the provisions of this subsection,
such claims will be considered by the owner in accordance with local laws or ordinances. Upon final
adjudication of such claims, any additional payment determined to be due the Contractor will be paid pursuant
to a supplemental final estimate.

(2) Test designation;
(3) Location;
(4) Date of test;
(5) Control requirements;
(6) Test results;
(7) Causes for rejection;
(8) Recommended remedial actions; and
(9) Retests.
Test results from each day's work period shall be submitted to the Engineer prior to the start of the next day's
work period. When required by the technical specifications, the Contractor shall maintain statistical quality
control charts. The daily test reports shall be signed by the responsible quality control technician and the
Program Administrator.
100-09 CORRECTIVE ACTION REQUIREMENTS. The Quality Control Program shall indicate the
appropriate action to be taken when a process is deemed, or believed, to be out of control (out of tolerance)
and detail what action will be taken to bring the process into control. The requirements for corrective action
shall include both general requirements for operation of the Quality Control Program as a whole, and for
individual items of work contained in the technical specifications.
The Quality Control Program shall detail how the results of quality control inspections and tests will be used
for determining the need for corrective action and shall contain clear sets of rules to gauge when a process is
out of control and the type of correction to be taken to regain process control.
When applicable or required by the technical specifications, the Contractor shall establish and utilize
statistical quality control charts for individual quality control tests. The requirements for corrective action
shall be linked to the control charts.
100-10 SURVEILLANCE BY THE ENGINEER. All items of material and equipment shall be subject to
surveillance by the Engineer at the point of production, manufacture or shipment to determine if the
Contractor, producer, manufacturer or shipper maintains an adequate quality control system in conformance
with the requirements detailed herein and the applicable technical specifications and plans. In addition, all
items of materials, equipment and work in place shall be subject to surveillance by the Engineer at the site for
the same purpose.
Surveillance by the Engineer does not relieve the Contractor of performing quality control inspections of
either on -site or off -site Contractor's or subcontractor's work.
100-11 NONCOMPLIANCE.
a. The Engineer will notify the Contractor of any noncompliance with any of the foregoing
requirements. The Contractor shall, after receipt of such notice, immediately take corrective action.
Any notice, when delivered by the Engineer or his/her authorized representative to the Contractor or
his/her authorized representative at the site of the work, shall be considered sufficient notice.
b. In cases where quality control activities do not comply with either the Contractor's Quality
Control Program or the contract provisions, or where the Contractor fails to properly operate and
maintain an effective Quality Control Program, as determined by the Engineer, the Engineer may:
(1) Order the Contractor to replace ineffective or unqualified quality control personnel or
subcontractors.
(2) Order the Contractor to stop operations until appropriate corrective actions are taken.

METHOD OF ESTIMATING PERCENTAGE OF MATERIAL WITHIN SPECIFICATION
LIMITS (PWL)
110-01 GENERAL. When the specifications provide for acceptance of material based on the method of
estimating percentage of material within specification limits (PWL), the PWL will be determined in
accordance with this section. All test results for a lot will be analyzed statistically to determine the total
estimated percent of the lot that is within specification limits. The PWL is computed using the sample
average (X) and sample standard deviation (Sn ) of the specified number (n) of sublots for the lot and the
specification tolerance limits, L for lower and U for upper, for the particular acceptance parameter. From
these values, the respective Quality index(s), QL for Lower Quality Index and/or Qu for Upper Quality Index,
is computed and the PWL for the lot for the specified n is determined from Table 1. All specification limits
specified in the technical sections shall be absolute values. Test results used in the calculations shall be to the
significant figure given in the test procedure.
There is some degree of uncertainty (risk) in the measurement for acceptance because only a small fraction of
production material (the population) is sampled and tested. This uncertainty exists because all portions of the
production material have the same probability to be randomly sampled. The Contaractor's risk is the
probability that material produced at the acceptable quality level is rejected or subjected to a pay adjustment.
The Owner's risk is the probability that material produced at the rejectable quality level is accepted.
IT IS THE INTENT OF THIS SECTION TO INFORM THE CONTRACTOR THAT, IN ORDER TO
CONSISTENTLY OFFSET THE CONTRACTOR'S RISK FOR MATERIAL EVALUATED,
PRODUCTION QUALITY (USING POPULATION AVERAGE AND POPULATION STANDARD
DEVIATION) MUST BE MAINTAINED AT THE ACCEPTABLE QUALITY SPECIFIED OR HIGHER.
IN ALL CASES, IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO PRODUCE AT QUALITY
LEVELS THAT WILL MEET THE SPECIFIED ACCEPTANCE CRITERIA WHEN SAMPLED AND
TESTED AT THE FREQUENCIES SPECIFIED.
110-02 METHOD FOR COMPUTING PWL. The computational sequence for computing the PWL is as
follows:
a. Divide the lot into n sublots in accordance with the acceptance requirements of the
specification.
b. Locate the sampling position within the sublot in accordance with the random sampling
requirements of the specification.
C. Make a measurement at each location, or take a test portion and make the measurement on the
test portion in accordance with the testing requirements of the specification.
d. Average all sublot values within the lot to find X by using the following formula:
X= (XI +X2+X3-h...Xn)/n
Where:
X = Sample average of all sublot values within a lot
xl, X2 = Individual sublot values
n = Number of sublots
e. Find the standard deviation Sn by use of the following formula:
PAGE 48 GENERAL PROVISIONS
Sn = L (d12 + d22 + d32 + ...dn2) / n-11"2
Where:
Sn = Sample standard deviation of the number of sublot
values in the set
d,, d2 = Deviations of the individual sublot values
Xl, X2 ... from the average value X
that is d, = (xl - X), d2 = (x2 - X)..dn = (x,, - X)
n = Number of sublots
f. For single sided specification limits (i.e., L only), compute the Lower Quality Index QL by
use of the following formula:
QL=(X-L)/S.
Where:
L = specification lower tolerance limit
Estimate the percentage of material within limits (PWL) by entering Table 1 with QL, using
the column appropriate to the total number (n) of measurements. If the value of QL falls between
values shown on the table, use the next higher value of PWL.
g. For double sided specification limits (i.e., L and U), compute the Quality Indexes QL and
Qu by use of the following formulas:
QL=(X-L)/S„ and Qu=(U-X)/SIl
Where:
L and U = specification lower and upper tolerance limits
Estimate the percentage of material between the lower (L) and upper (U) tolerance limits
(PWL) by entering Table I separately with QL and Qu, using the column appropriate to the total
number (n) of measurements, and determining the percent of material above PL and percent of material
below Pu for each tolerance limit. If the values of QL fall between values shown on the table, use the
next higher value of PL or Pu. Determine the PWL by use of the following formula:
PWL = (Pu + PL) - 100
Where:
PL = percent within lower specification limit
Pu = percent within upper specification limit
Extended values for Table 1 are available from the Engineer as necessary. They are contained in the FAA
Engineering Brief No. 57.
