or sent by registered mail to the last business address known to him who gives the notice.
The Contractor shall provide and pay for all materials, machinery, equipment, tools,
superintendence, labor, services, insurance, and all water, light, power, fuel,
transportation and other facilities necessary for the execution and completion of the work
covered by the contract documents. Unless otherwise specified, all materials shall be

1.08 Working Day
The term "Extra Work" as used in this contract shall be understood to mean and include
all work that may be required by the Engineer or Owner to be done by the Contractor
to accomplish any change, alteration or addition to the work shown upon the plans, or
reasonably implied by the specifications, and not covered by the Contractor's Proposal,
except as provided under "Changes and Alteration," herein.
A "Working Day" is defined as any day not including Saturdays, Sundays or any legal
holidays, in which weather or other conditions, not under the control of the Contractor,

GC -5
2. Responsibilities of the Engineer and the Contractor
2.01 Owner - Engineer Relationship
gentond/dh2
The Engineer will be the Owner's representative during construction. The duties,
responsibilities and limitations of authority of the Engineer as the Owner's representative
during construction are as set forth in the Contract Documents and shall not be extended
or limited without written consent of the Owner and Engineer. The Engineer will advise
and consult with the Owner, and all of Owner's instructions to the Contractor shall be
issued through the Engineer.
2.02 Professional Inspection by Engineer
The Engineer shall make periodic visits to the site to familiarize himself generally with
the progress of the executed work and to determine if such work generally meets the
essential performance and design features and the technical and functional engineering
requirements of the Contract Documents; provided and except, however, that the
Engineer shall not be responsible for making any detailed, exhaustive, comprehensive or
continuous on -site inspection of the quality or quantity of the work or be in any way
responsible, directly or indirectly, for the construction means, methods, techniques,
sequences, quality, procedures, programs, safety precautions or lack of same incident
thereto or in connection therewith. Notwithstanding any other provision of this
agreement or any other Contract Document, the Engineer shall not be in any way
responsible or liable for any acts, errors, omissions or negligence of the Contractor, any
Subcontractor or any of the Contractor's or Subcontractor's agents, servants or
employees or any other person, firm or corporation performing or attempting to perform
any of the work.
2.03 Payments for Work
The Engineer shall review Contractor's applications for payment and supporting data,
determine the amount owed to the Contractor and recommend, in writing, payment to
Contractor in such amounts; such recommendation of payment to Contractor constitutes
a representation to the Owner of Engineer's professional judgement that the work has
progressed to the point indicated to the best of his knowledge, information and belief,
but such recommendation of an application for payment to Contractor shall not be
deemed as a representation by Engineer that Engineer has made any examination to
determine how or for what purpose Contractor has used the moneys paid on account of
the Contract price.
GC -6
2.04 Initial Determinations
The Engineer initially shall determine all claims, disputes and other matters in question
between the Contractor and the Owner relating to the execution or progress of the work
or the interpretation of the Contract Documents and the Engineer's decision shall be
rendered in writing within a reasonable time, which shall not be construed to be less than
ten (10) days. Appeal to arbitration upon mutual agreement may be taken as if his
decision had been rendered against the party appealing.
2.05 Objections
In the event the Engineer renders any decision which, in the opinion of either party
hereto, is not in accordance with the meaning and intent of this contract, either party may
file with the Engineer within thirty (30) days his written objection to the decision, and
by such action may reserve the right to submit the question so raised to arbitration as
hereinafter provided.
2.06 Lines and Grades
Unless otherwise specified, all lines and grades shall be furnished by the Engineer or his
representative. Whenever necessary, construction work shall be suspended to permit
performance of this work, but such suspension will be as brief as practicable and the
Contractor shall be allowed no extra compensation therefor. The contractor shall give
the Engineer ample notice of the time and place where lines and grades will be needed.
All stakes, marks, etc., shall be carefully preserved by the Contractor, and in case of
careless destruction or removal by him or his employees, such stakes, marks, etc., shall
be replaced at the Contractor's expense.
2.07 Contractor's Duty and Superintendence
`eaca,a dh2
The Contractor shall give adequate attention to the faithful prosecution and completion
of this contract and shall keep on the work, during its progress, a competent English -
speaking superintendent and any necessary assistants to supervise and direct the work.
The superintendent shall represent the Contractor in his absence and all directions given
to him shall be as binding as if given to the Contractor.
The Contractor is and at all times shall remain an independent contractor, solely
responsible for the manner and method of completing his work under this contract, with
full power and authority to select the means, method and manner of performing such
work, so long as such methods do not adversely affect the completed improvements, the
Owner and Engineer being interested only in the result obtained and conformity of such
completed improvements to the plans, specifications and contract.
Likewise, the Contractor shall be solely responsible for the safety of himself, his
GC -7
employees and other persons, as well as for the protection and safety of the
improvements being erected and the property of himself or any other person, as a result
of his operations hereunder. Engineering construction drawings and specifications as
well as any additional information concerning the work to be performed passing from or
through the Engineer shall not be interpreted as requiring or allowing Contractor to
deviate from the plans and specifications, the intent of such drawings, specifications and
any other such information being to define with specificity the agreement of the parties
as to the work the Contractor is to perform. Contractor shall be fully and completely
liable, at his own expense, for design, construction, installation and use, or non -use of
all items and methods incident to performance of the contract, and for all loss, damage
or injury incident thereto, either to person or property, including, without limitation, the
adequacy of all temporary supports, shoring, bracing, scaffolding, machinery or
equipment, safety precautions or devices, and similar items or devices used by him
during construction.
Any review of work in process, or any visit or observation during construction, or any
clarification of plans and specifications, by the Engineer or Owner, or any agent,
employee, or representative of either of them, whether through personal observation on
the project site or by means of approval of shop drawings for temporary construction or
construction processes, or by other means or method, is agreed by the Contractor to be
for the purpose of observing the extent and nature of work completed or being
performed, as measured against the drawings and specifications constituting the contract,
or for the purpose of enabling Contractor to more fully understand the plans and
specifications so that the completed construction work will conform thereto, and shall in
no way relieve the Contractor from full and complete responsibility for the proper
performance of his work on the project, including but not limited to the propriety of
means and methods of the Contractor in performing said contract, and the adequacy of
any designs, plans or other facilities for accomplishing such performance. Deviation by
the Contractor from plans and specifications that may have been in evidence during any
such visitation or observation by the Engineer, or any of his representatives, whether
called to the contractor's attention or not shall in no way relieve Contractor from his
responsibility to complete all work in accordance with said plans and specifications.
2.08 Contractor's Understanding
e andldb2
It is understood and agreed that the Contractor has, by careful examination, satisfied
himself as to the nature and location of the work, the conformation of the ground, the
character, quality and quantity of the materials to be encountered, the character of
equipment and facilities needed preliminary to and during the prosecution of the work,
the general and local conditions, and all other matters which can in any way effect the
work under this contract. The Contractor agrees that he will make no claim against the
Owner or the Engineer if, in the prosecution of the work, he finds that the actual site or
subsurface conditions encountered do not conform to those indicated by excavation, test
excavation, test procedures, borings, explorations or other subsurface excavations. No
GC -8
verbal agreement or conversation with any officer, agent or employee of the Owner or
Engineer either before or after the execution of this contract, shall affect or modify any
of the terms or obligations herein contained.
2.09 Character of Workers
The Contractor agrees to employ only orderly and competent workers, skillful in the
performance of the type of work required under this contract, to do the work; and agrees
that whenever the Engineer shall inform him in writing that any workers on the work
are, in his opinion, incompetent, unfaithful or disorderly, or refuse instructions from the
Engineer in the absence of the Superintendent, such worker shall be discharged from the
work and shall not again be employed on the work without the Engineer's written
consent. No illegal alien may be employed by any Contractor for work on this project,
and a penalty of $500.00 per day will be assessed for each day and for each illegal alien
who works for the Contractor at this project.
2.10 Contractor's Buildings
gcced/dh.2
The building of structures for housing workers, or the erection of tents or other forms
of protection, will be permitted only at such places as the Engineer shall direct, and the
sanitary conditions of the grounds in or about such structures shall at all times be
maintained in a manner satisfactory to the Engineer.
2.11 Sanitation
Necessary sanitary conveniences for the use of laborers on the work, properly secluded
from public observation, shall be constructed and maintained by the Contractor in such
manner and at such points as shall be approved by the Engineer, and their use shall be
strictly enforced.
2.12 Shop Drawings
The Contractor shall submit to the Engineer, with such promptness as to cause no delay
in his own work or in that of any other Contractor, four (4) checked copies, unless
otherwise specified, of all shop and /or setting drawings and schedules required for the
work of the various trades, and the Engineer shall pass upon them with reasonable
promptness, making desired corrections. The Contractor shall make any corrections
required by the Engineer, file with him two (2) corrected copies and furnish such other
copies as may be needed. The Engineer's review of such drawings or schedules shall
not relieve the Contractor from responsibility for deviations from drawings or
specifications, unless he has in writing called the Engineer's attention to such deviations
at the time of submission, nor shall it relieve him from responsibility for errors of any
sort in shop drawings or schedules. It shall be the Contractor's responsibility to fully
and completely review all shop drawings to ascertain their effect on his ability to perform
GC -9
gazond/db2
the required contract work in accordance with the plans and specifications and within the
contract time.
Such review by the Engineer shall be for the sole purpose of determining the general
conformity of said shop drawings or schedules to result in finished improvements in
conformity with the plans and specifications, and shall not relieve the Contractor of his
duty as an independent contractor as previously set forth, it being expressly understood
and agreed that the Engineer does not assume any duty to pass upon the propriety or
adequacy of such drawings or schedules, or any means or methods reflected thereby, in
relation to the safety of either person or property during Contractor's performance
hereunder.
2.13 Preliminary Approval
The Engineer shall not have the power to waive the obligations of this contract for the
furnishing by the Contractor of good material, and of his performing good work as
herein described, and in full accordance with the plans and specifications. No failure or
omission of the Engineer to discover, object to or condemn any defective work or
material shall release the Contractor from the obligations to fully and properly perform
the contract, including without limitations, the obligation to at once tear out, remove and
properly replace the same at any time prior to final acceptance upon the discovery of said
defective work or material; provided, however, that the Engineer shall, upon request of
the Contractor, inspect and accept or reject any material furnished, and in event the
material has been once accepted by the Engineer, such acceptance shall be binding on the
Owner, unless it can be clearly shown that such material furnished does not meet the
specifications for this work.
Any questioned work may be ordered taken up or removed for re- examination, by the
Engineer, prior to final acceptance, and if found not in accordance with the plans and/or
specifications for said work, all expense of removing, re- examination and replacement
shall be borne by the Contractor, otherwise the expense thus incurred shall be allowed
as Extra Work, and shall be paid for by the Owner; provided that, where inspection or
approval is specifically required by the specifications prior to performance of certain
work, should the Contractor proceed with such work without requesting prior inspection
or approval he shall bear all expense of taking up, removing, and replacing this work if
so directed by the Engineer.
2.14 Defects and Their Remedies
It is further agreed that if the work or any part thereof, or any material brought on the
site of the work for use in the work or selected for the same, shall be deemed by the
Engineer as unsuitable or not in conformity with the plans, specifications, or the intent
thereof, the Contractor shall after receipt of written notice thereof from the Engineer,
forthwith remove such material and rebuild or otherwise remedy such work so that it
GC -10
shall be in full accordance with this contract.
2.15 Changes and Alterations
gc ond/dbz
The Contractor further agrees that the Owner may make such changes and alterations as
the Owner may see fit, in the line, grade, form, dimensions, plans or materials for the
work herein contemplated, or any part thereof, either before or after the beginning of the
construction, without affecting the validity of this contract and the accompanying
Performance and Payment Bonds.
If such changes or alterations diminish the quantity of the work to be done, they shall not
constitute the basis for a claim for damages, or anticipated profits on the work that may
be dispensed with, except as provided for unit price items under Section 5 "Measurement
and Payment ". If the amount of work is increased, and the work can fairly be classified
under the specifications, such increase shall be paid for according to the quantity actually
done and at the unit price, if any, established for such work under this contract, except
as provided for unit price items under Section 5 "Measurement and Payment "; otherwise,
such additional work shall be paid for as provided under Extra Work. In case the Owner
shall make such changes or alterations as shall make useless any work already done or
material already furnished or used in said work, then the Owner shall recompense the
Contractor for any material or labor so used, and for any actual loss occasioned by such
change, due to actual expense incurred in preparation for the work as originally planned.
2.16 Inspectors
The Engineer may provide one (or more) field inspectors at the work site for the limited
purpose of observing the work in progress and reporting back to the Engineer on the

clearly all work to be done and material to be furnished hereunder. Where the estimated
quantities are shown for the various classes of work to be done and material to be
furnished under this contract, they are approximate and are to be used only as a basis for
estimating the probable cost of the work and for comparing the proposals offered for the
GC -20
work. It is understood and agreed that the actual amount of work to be done and
material to be furnished under this contract may differ somewhat from these estimates,
and that where the basis for payment under this contract is the unit price method,
payment shall be for the actual amount of such work done and material furnished.
Where payment is based on the unit price method, the Contractor agrees that he will

material actually furnished under this contract and the estimated quantities contemplated
and contained in the proposal; provided, however, that in case the actual quantity of any
major item should become as much as 20% more than, or 20% less than the estimated
or contemplated quantity for such items, then either party to this Agreement, upon
demand, shall be entitled to revised consideration upon the portion of the work above or
below 20% of the estimated quantity.
A "Major Item" shall be construed to be any individual bid item incurred in the proposal

The Owner shall have the right to take possession of and use any completed or partially
completed portions of the work, notwithstanding the time for completing the entire work

Engineer may determine.
The Contractor shall notify the Engineer when, in the Contractor's opinion, the contract
is "substantially completed" and when so notifying the Engineer, the Contractor shall

Compensation, and all other insurance as may be required by any law or ordinance, or
directed by the Owner, or by them agreed to. The Engineer may direct the form in
which accounts of the "actual field cost" shall be kept and the records of these accounts
shall be made available to the Engineer. The Engineer or Owner may also specify in
writing, before the work commences, the method of doing the work and the type and
kind of machinery and equipment to be used; otherwise these matters shall be determined
by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery
and equipment shall be determined by using 100 per cent, unless otherwise specified, of
the latest schedule of Equipment Ownership Expense adopted by the Associated General
Contractors of America. Where practicable the terms and prices for the use of
machinery and equipment shall be incorporated in the Written Extra Work Order. The
fifteen (15 %) percent of the "actual field cost" to be paid the Contractor shall cover and
compensate him for his profit, overhead, general superintendence and field office
expense, and all other elements of cost and expense not embraced within the "actual field
GC -25
`cneond/dh2
cost" as herein defined, save that where the Contractor's Camp or Field Office must be
maintained primarily on account of such Extra Work; then the cost to maintain and
operate the same shall be included in the "actual field cost."
No claim for Extra Work of any kind will be allowed unless ordered in writing by the
Engineer. In case any orders or instructions, either oral or written, appear to the
Contractor to involve Extra Work for which he should receive compensation or an
adjustment in the construction time, he shall make written request to the Engineer for
written order authorizing such Extra Work. Should a difference of opinion arise as to
what does or does not constitute Extra Work, or as to the payment therefor, and the
Engineer insists upon its performance, the Contractor shall proceed with the work after
making written request for written order and shall keep an accurate account of the "actual
field cost" thereof, as provided under Method (C). The Contractor will thereby preserve
the right to submit the matter of payment to arbitration, as hereinbelow provided.
6.04 Time of Filing Claims
It is further agreed by both parties hereto that all questions of dispute or adjustment
presented by the Contractor shall be in writing and filed with the Engineer within thirty
(30) days after the Engineer has given any directions, order or instruction to which the
Contractor desires to take exception. The Engineer shall reply within thirty (30) days
to such written exceptions by the Contractor and render his final decision in writing. In
case the Contractor should appeal from the Engineer's decision, any demand for
arbitration shall be filed with the Engineer and the Owner in writing within ten (10) days
after the date of delivery to Contractor of the Engineer's final decision. It is further
agreed that final acceptance of the work by the Owner and the acceptance by the
Contractor of the final payment shall be a bar to any claims by either party, except
claims by Owner for defective work or enforcement of warranties and except as noted
otherwise in the contract documents.
6.05 Continuing Performance
The Contractor shall continue performance of the contract during all disputes or
disagreements with the Owner. The production or delivery of goods, the furnishing of
services and the construction of projects or facilities shall not be delayed, prejudiced or
postponed pending resolution of any disputes or disagreements, except as the Owner may
otherwise agree in writing.
6.06 Arbitration
All questions of dispute under this Agreement shall be submitted to arbitration at the
request of either party to the dispute. The parties may agree upon one arbiter, otherwise,
there shall be three, one named in writing by each party, and the third chosen by the two
arbiters so selected; or if the arbiters fail to select a third within ten (10) days, he shall
GC -26
be chosen by a District Judge serving the County in which the major portion of the
project is located, unless otherwise specified. Should the party demanding arbitration fail
to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse,
and the decision of the Engineer shall be final and binding on him. Should the other
party fail to choose an arbiter within ten (10) days, the Engineer shall appoint such
arbiter. Should either party refuse or neglect to supply the arbiters with any papers or
information demanded in writing, the arbiters are empowered by both parties to take ex
parte proceedings.
The arbiters shall act with promptness. The decision of any two shall be binding on both
parties to the contract. The decision of the arbiters upon any questions submitted to
arbitration under this contract shall be a condition precedent to any right of legal action.
The decision of the arbiter or arbiters may be filed in court to carry it into effect.
The arbiters, if they deem the case demands it, are authorized to award the party whose
contention is sustained, such sums as they deem proper for the time, expense and trouble
incident to the appeal, and if the appeal was taken without reasonable cause, they may
award damages for any delay occasioned thereby. The arbiters shall fix their own
compensation unless otherwise provided by agreement, and shall assess the cost and
charges of the arbitration upon either or both parties. The award of the arbiters must be
made in writing.
7. Abandonment of Contract
7.01 Abandonment by Contractor
g,«ond/dh2
In case the Contractor should abandon and fail or refuse to resume work within ten (10)
days after written notification from the Owner, or the Engineer, or if the Contractor fails
to comply with the orders of the Engineer, when such orders are consistent with the
Contract Documents, then, and in that case, where performance and payment bonds
exist, the Sureties on these bonds shall be notified in writing and directed to complete
the work, and a copy of said notice shall be delivered to the Contractor.
After receiving said notice of abandonment the Contractor shall not remove from the
work any machinery, equipment, tools, materials or supplies then on the job, but the
same, together with any materials and equipment under contract for the work, may be
held for use on the work by the Owner or the Surety on the performance bond, or
another contractor in completion of the work; and the Contractor shall not receive any
rental or credit therefor (except when used in connection with Extra Work, where credit
shall be allowed as provided for under Section 6, Extra Work and Claims), it being
understood that the use of such equipment and materials will ultimately reduce the cost
to complete the work and be reflected in the final settlement.

Where there is no performance bond provided or in case the Surety should fail to
commence compliance with the notice for completion hereinbefore provided for, within
ten (10) days after service of such notice, then the Owner may provide for completion
of the work in either of the following elective manners:
(1)
The Owner may thereupon employ such force of men and use such
machinery, equipment, tools, materials and supplies as said Owner may
deem necessary to complete the work and charge the expense of such
labor, machinery, equipment, tools, materials and supplies to said
Contractor, and expense so charged shall be deducted and paid by the
Owner out of such moneys as may be due, or that may thereafter at any
time become due to the Contractor under and by virtue of this Agreement.
In case such expense is less than the sum which would have been payable
under this contract, if the same had been completed by the Contractor,
then said Contractor shall receive the difference. In case such expense is
greater than the sum which would have been payable under this contract,
if the same had been completed by said Contractor, then the Contractor
and /or his Surety shall pay the amount of such excess to the Owner, or
(2) The Owner under competitive bids, taken after notice published as
required by law, may let the contract for the completion of the work under
substantially the same terms and conditions which are provided in this
contract. In case there is any increase in cost to the Owner under the new
contract as compared to what would have been the cost under this
contract, such increase shall be charged to the Contractor and the Surety
shall be and remain bound therefor. However, should the cost to
complete any such contract prove to be less than would have been the cost
to complete under this contract, the Contractor and /or his Surety shall be
credited therewith.
When the work shall have been substantially completed the Contractor and his Surety
shall be so notified and Certificates of Completion and Acceptance, as provided in
Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the
contract accounts, certified to by the Engineer as being correct, shall then be prepared
and delivered to the Contractor and his Surety, whereupon the Contractor and /or his
Surety, or the Owner as the case may be, shall pay the balance due as reflected by said
statement, within fifteen (15) days after the date of such Certificate of Completion.
In the event the statement of accounts shows that the cost to complete the work is less
than that which would have been the cost to the Owner had the work been completed by
the Contractor under the terms of this contract; or when the Contractor and /or his Surety
shall pay the balance shown to be due by them to the owner, then all machinery,
equipment, tools, materials or supplies left on the site of the work shall be turned over
to the Contractor and /or his Surety. Should the cost to complete the work exceed the
GC -28
1
' contract price, and the Contractor and /or his Surety fail to pay the amount due the Owner
within the time designated hereinabove, and there remains any machinery, equipment,
tools, materials or supplies on the site of the work, notice thereof, together with an
1 itemized list of such equipment and materials, shall be mailed to the Contractor and his
Surety at the respective addresses designated in this contract, provided, however, that
actual written notice given in any manner will satisfy this condition. After mailing, or
1 other giving of such notice, such property shall be held at the risk of the Contractor and
his Surety subject only to the duty of the Owner to exercise ordinary care to protect such
property. After fifteen (15) days from the date of said notice the Owner may sell such
machinery, equipment, tools, materials or supplies and apply the net sum derived from
such sale to the credit of the Contractor and his Surety. Such sale may be made at either
' public or private sale, with or without notice, as the Owner may elect. The Owner shall
release any machinery, equipment, tools, materials, or supplies, which remain on the
work, and belong to persons other than the Contractor or his Surety, to their proper
owners. The books on all operations provided herein shall be opened to the Contractor
and his Surety.
7.02 Abandonment by Owner
In case the Owner shall fail to comply with the terms of this contract, and should fail to
1 comply with said terms within ten (10) days after written notification by the Contractor,
then the Contractor may suspend or wholly abandon the work, and may remove
therefrom all machinery, tools and equipment, and all materials on the site of work that
1 have not been included in payments to the Contractor and have not been wrought into the
work. And thereupon the Engineer shall make an estimate of the total amount earned
by the Contractor, which estimate shall include the value of all work actually completed
by said Contractor (at the prices stated in the attached proposal where unit prices are
used), the value of all partially completed work at a fair and equitable price, and the
amount of all Extra Work performed at the prices agreed upon, or provided for by the
terms of this contract, and a reasonable sum to cover the cost of any provisions made by
the Contractor to carry the whole work to completion and which cannot be utilized. The
' Engineer shall then make a final statement of the balance due the Contractor by deducting
from the above estimate all previous payments by the Owner and all other sums that may
be retained by the Owner under the terms of this Agreement and shall certify same to the
1 Owner who shall pay to the Contractor on or before thirty (30) days after the date of the
notification by the Contractor the balance shown by said final statement as due the
Contractor, under the terms of this Agreement.

the Subcontractors proposed for the principal portions of the work. The Engineer shall
promptly notify the Contractor in writing if either the Owner or the Engineer, after due
investigation, has reasonable objection to any Subcontractor on such list and does not
accept him. Failure of the Owner or Engineer to make objection promptly to any
Subcontractor on the list shall constitute acceptance of such Subcontractor.
The Contractor shall not contract with any Subcontractor or any person or organization
(including those who are to furnish materials or equipment fabricated to a special design)
proposed for portions of the work designated in the Contract Documents or in the
Instructions to Bidders or, if none is so designated, with any Subcontractor proposed for
the principal portions of the work who has been rejected by the Owner and the Engineer.
The Contractor will not be required to contract with any Subcontractor or person or
organization against whom he has a reasonable objection.
If the Owner or Engineer refuses to accept any Subcontractor or person or organization
on a list submitted by the Contractor in response to the requirements of the Contract

unless the Contractor has acted promptly and responsively in submitting for acceptance
any list or lists of names as required by the Contract Documents or the Instructions to
Bidders.
If the Owner or the Engineer requires a change of any proposed Subcontractor or person
or organization previously accepted by them, the Contract amount shall be increased or
decreased by the difference in cost occasioned by such change and an appropriate Change
Order shall be issued.
The Contractor shall not make any substitution for any Subcontractor or person or
organization who has been accepted by the Owner and the Engineer, unless the
substitution is acceptable to the Owner and the Engineer.
8.02 Subcontractual Relations
All work performed for the Contractor by a Subcontractor shall be pursuant to an
appropriate written agreement between the Contractor and the Subcontractor (and where

section.
A copy of all such Subcontract Agreements shall be filed by the Contractor with the
Engineer before the Subcontractor shall be allowed to commence work.
8.03 Payments to Subcontractors
The Contractor shall pay each Subcontractor, upon receipt of payment from the Owner,
an amount directly based upon the value of the work performed and allowed to the
Contractor on account of such Subcontractor's work, less the percentage retained from
payments to the Contractor. The Contractor shall also require each Subcontractor to
make similar payments to his subcontractors.
If the Engineer fails to approve a payment for any cause which is the fault of the
Contractor and not the fault of a particular Subcontractor, the Contractor shall pay the
Subcontractor on demand, made at any time after the Certificate for Payment should
otherwise have been issued, for his work to the extent completed, less the retained
percentage.
The Engineer may, on request and at his discretion, furnish to any Subcontractor, if
practicable, information regarding percentages of completion certified to the Contractor
on account of work done by such Subcontractors.
Neither the Owner nor the Engineer shall have any obligation to pay or to see to the

work of any other separate contractor, the Contractor shall inspect and promptly report
to the Engineer any apparent discrepancies or defects in such work that render it
unsuitable for such proper execution and results. Failure of the Contractor to so inspect
and report shall constitute an acceptance of the other contractor's work as fit and proper
to receive his Work, except as to defects which may develop in the other separate
contractor's work after the execution of the Contractor's Work.
Should the Contractor cause damage to the work or property of any separate contractor
on the project, the Contractor shall, upon due notice, settle with such other contractor
by agreement or arbitration, if he will so settle. If such separate contractor sues the
Owner or initiates an arbitration proceeding on account of any damage alleged to have
been so sustained, the Owner shall notify the Contractor who shall defend such

arises therefrom the Contractor shall pay or satisfy it and shall reimburse the Owner for
all attomey's fees and court or arbitration costs which the Owner has incurred.

Minimum compressive strength when subjected to the triaxial test: 35 psi at 0 psi lateral pressure and 175 psi at 15 psi lateral
pressure, unless otherwise indicated.
210.3 Stockpiling, Storage and Management
(1) Managing Aggregates
Prior to stockpiling of aggregates, the area shall be cleaned of trash, weeds and grass and be relatively smooth.
Stockpiles should be constructed to between 20,000 and 40,000 cubic yards in size. The size should be limited to the
ability of the available equipment to construct, mix and test the pile. The stockpile shall be constructed utilizing
equipment such as a scraper, a bottom dump or other acceptable equipment that allows spreading when dumped
without rehandling. The stockpile shall be constructed to allow dump spreading in 1 direction only. Height of stockpile
shall not exceed the capabilities of available machinery to make a full cut (bottom to top) on any of the 4 sides.
The City will test a completed stockpile. The stockpile shall not be added to after it has been tested.
The Contractor shall assure that only material from a City approved stockpile receives a weight ticket indicating an
approved stockpile number. The liability for accuracy of the weight ticket, as to items such as stockpile number or an
approved source, is solely that of the Contractor. Use full height cuts and mix the material during loading operations.
The Inspector shall be given a weigh ticket at the time of delivery indicating the source, stockpile approval number
and weight.
(2) Test Sampling
The Contractor may choose the method of sample gathering for testing by City Testing Consultants as follows:
(a) The Contractor shall make a full height cut from each side of the stockpile. The 4 samples are then
Page 1 04/17/86 210
combined and mixed into a single "test" specimen from which the City's Testing Consultant can draw Its
samples.
(b) As the stockpile is constructed, a perpendicular cut is to be made across the spreading direction at every
2 feet to 4 feet of height and the sample used to start a "mini" stockpile. Repeat the process, in 2 feet to 4
feet increments of heights, until the stockpile and the "mini" stockpile are completed. The Contractor
shall provide access to samples from the "mini" stockpile for the City's Testing Consultant to draw its
samples.
210.4 Construction Methods
(1) Preparation of Subgrade
"Flexible Base" shall not be placed until the Contractor has verified, by proof rolling, that the subgrade has been
prepared and compacted in conformity with Item No. 201, " Subgrade Preparation" to the typical sections, lines and
grades indicated. Any deviation shall be corrected and proof rolled prior to placement of aggregate.
Blue tops shall be set by the Contractor for subgrade on centerline, quarter points, curb lines or edge of pavement
where curb is omitted, at intervals not exceeding 50 feet. Subgrade shall be tested by proof rolling in conformity with
Item No. 236, "Rolling (Proof)" prior to placing first course of base material.
(2) First Course
Immediately before placing the base material, the subgrade shall be checked as to conformity with grade and sec-
tion. The thickness of each base course shall not exceed 6 inches, loose measure and will be equal increments of
the total depth.
The material shall be delivered in approved vehicles and it shall be the responsibility of the Contractor that the re-
quired amount of specified material shall be delivered. Material deposited upon the subgrade shall be spread and
shaped the same day unless otherwise approved by the Engineer. In the event inclement weather or other unfore-
seen circumstances render impractical spreading of the matenal during the first 24 hour period, the material shall be
spread as soon as conditions allow. The material shall be sprinkled, if required, and shall then be bladed, dragged
and shaped to conform to typical sections as indicated. All areas and "nests" of segregated course or line material
shall be corrected or removed and replaced with well graded material. If additional binder is considered desirable or
necessary after the matenal is spread and shaped, it shall be furnished and applied as required. Such binder mate-
rial shall be carefully and evenly incorporated with the material in place by scarifying, harrowing, brooming or by
other approved methods.
The course shall be sprinkled as required to bring it to optimum moisture content and compacted to the extent nec-
essary to provide not less than the percent density as hereinafter specified under "Density'. In no case shall the
base be worked at more than 2 percent above or below optimum moisture. In addition to the requirements specified
for density, the lull depth of flexible base indicated shall be compacted to the extent necessary to remain firm and
stable under construction equipment. After each section of flexible base is completed, tests as necessary will be.
made by the Engineer. If the material fails to meet the density requirements, ft shall be reworked as necessary to
meet these requirements. Throughout this entire operation the shape of the base course shall be maintained by
blading and the surface, upon completion, shall be smooth and in conformity with the typical section indicated and to
the established lines and grades. In that area on which pavement is to be placed, any deviation in excess of V. inch
in cross section and in length of 16 feet measured longitudinally shall be corrected by loosening, adding or removing
material, reshaping and recompacting by sprinkling and rolling. All irregularities, depressions or weak spots which
develop shall be corrected immediately by scarifying the areas affected, adding suitable material as required, re-
shaping and recompacting by sprinkling and rolling. Should the base course, due to any reason or cause, lose the
required stability, density and finish before the surfacing is complete, it shall be recompacted and refinished at the
sole expense of the Contractor.
(3) Succeeding Courses

segregation of the aggregates does not occur.
340.6 Mixing
(1) General
(a) Asphaltic Mixture
The asphaltic mixture from each type of mixer shall be a temperature between 240 F and 350 F when dis-
charged from the mixer and shall be adjusted to provide the best compaction temperature for the weather
conditions. The Contractor will determine the temperature, within the above limitations and the mixture when
discharged from the mixer shall not vary from this selected temperature more than 25 F.
(2) Batch Type Mixer
In the charging of the weigh box and in the charging of the mixer from the weigh box, such methods or devices shall
be used as are necessary to discharge the mixer in a manner which will prevent segregation.
(3) Dryer -Drum Mixer
The amount of aggregate and asphaltic materials entering the dryer -drum mixer and the rate of travel through the
mixing unit shall be so coordinated that a uniform mixture of the specified grading and asphalt content will be
produced without segregation.
340.7 Storing Mixture
Temporary storing or holding of the asphaltic mixture in insulated surge or storage systems may be used, provided the mixture is
not stored overnight or for more than 15 hours and the mixture does not segregate in or upon discharge from the system. The
mixture when discharged from the plant surge storage bin shall have a moisture content not greater than 1 percent by weight and
must be of equal quality to that coming out of the mixer. The moisture content shall be determined in accordance with SDHPT
Test Method Tex - 212 -F, Part II.
340.8 Construction Methods
It shall be the responsibility of the Contractor to produce. transport, place and compact the specified paving mixture in accor-
dance with these specifications and provide a safe environment to enable inspection forces to take samples and check the plant
Prior to placing HMAC, the base shall be proof rolled and any soft spots repaired and the area proof rolled again.
The asphaltic mixture, when placed with a motor grader for leveling, shall not be placed when air temperature is below 50 F and
falling. The air temperature shall be taken in the shade away from artificial heat. Mat thickness of 1' inches and less shall not be
placed when the temperature of the surface on which the mat is to be placed is below 50 F.
All asphaltic mixture, except that described above for leveling, shall be placed with a spreading and finishing machine. If, after
being discharged from the mixer and prior to placing, the temperature of the asphaltic mixture is 50 F or more below the tempera-
ture established, all or any part of the load may be rejected and payment will not be made for the rejected material. Any material
placed which is too cool to compact properly shall be removed and replaced with material which meets the specifications.
Adjacent to flush curbs, gutters, liners and structures, the surface shall be finished uniformly high so that when compacted it will
be slightly above the edge of the curb and flush structure. The compacted thickness of the asphaltic concrete courses shall be as
indicated. Where the thickness of the surface course is specified to be more than 2 inches, the work shall be accomplished in
equal lifts, unless otherwise indicated. When the surface is to be constructed in stages and traffic is permitted on the initial layer,
each layer shall be not less than 1 inch.
The final lilt of HMAC shall not be placed adjacent to an existing cured rounded edge asphalt surface until the existing surface
has been prepared.
Page5 04'17/86 340
(1) Prime Coat
If a prime coat is indicated, it shall be applied conforming to Item No. 306, "Prime Coat ", except the application
temperature shall be as provided above. The asphaltic concrete shall not be applied on a previously primed flexible
base until the primed base has cured to the satisfaction of the Engineer.
(2) Tack Coat
If a lack coat is indicated, it shall be applied conforming to Item No. 307, "Tack Coat". Before the asphaltic mixture is
placed, the surface upon which the tack coat is to be placed shall be cleaned thoroughly to the satisfaction of the
Engineer. The surface shall be given a uniform application of tack coat using asphaltic materials of this specification.
This tack coat shall be applied, as directed by the Engineer. Where the mixture will adhere to the surface of which it
is to be placed without the use of a tack coat, the tack coat may be eliminated by the Engineer. All contact surfaces of
curbs and structures and all joints shall be painted with a thin uniform coat of the asphaltic material meeting the
requirements for tack coat. The tack coat shall be rolled with a light pneumatic tire roller when directed by the
Engineer.
(3) Compacting
The mix shall be compressed thoroughly and uniformly compacted immediately after placing to the required density.
All compaction rolling shall be complete before the mat cools below 175 F. Minor polishing rolling may be undertaken
on the mat below the above temperature.
All rollers must be in good mechanical condition. Necessary precautions shall be taken to prevent the dropping of
gasoline, oil, grease or other foreign matter on the pavement, either when the rollers are in operation or when
standing.
It is the intent of this specification that the material be placed and compacted to a minimum of 92.5 percent of the
maximum theoretical density as determined by SDHPT Tex - 227 -F. The Engineer will secure 6 inch core samples or
sections of completed asphaltic pavement lifts for approximately every 2,000 square yards or part thereof, of
asphaltic concrete pavement placed. The in place density at the sampled locations shall be determined by the fol-
lowing equation:
340 04/17/86 Page 6
G A
Percent in place Density = x 100
G
T
Where GA = Bulk specific gravity of core when tested in accordance with Tex -207 -F
GT = Maximum theoretical specific gravity of combined cores when tested in accordance with Tex -227 -F
The Contractor shall patch the surface where specimens are taken with no extra payment being made for this work.
The Engineer will remove the asphaltic concrete pavement specimen on the day following placement or as soon as
practicable thereafter. Other methods of determining in place density which correlate satisfactorily with those results
obtained by cores or sections may be used.
The initial sampling and testing of in place asphalt concrete will be at no cost to the Contractor, except for the cost of
material and restoration of damage by testing. Retesting expense will conform to Section 00344, "Testing Labora-
tory Services'.
(4) Surface Tests
The surface of the pavement, after compaction, shall be smooth and true to the established line, grade and cross
section, and when tested with a 10 toot straightedge placed parallel to the centerline of the roadway or tested by
other equivalent and acceptable means, except as provided herein, the maximum deviation shall not exceed Vs inch
in 10 feet and any point in the surface not meeting this requirement shall be corrected. The completed surface shall
meet the approval of the Engineer for riding surface, finish and appearance.
(5) Opening to Traffic
The pavement shall be opened to traffic as soon as possible after temporary pavement markings or permanent
pavement markings are in place as Indicated and the Engineer concurs to the opening. The Contractor's attention is
directed to the fact that all construction traffic allowed on pavement open to the public will be subject to the City
Ordinances and State Laws governing traffic on streets and highways.
Surface raveling, cracking, segregation and other defects shall be corrected at the Contractor's expense as directed
by the Engineer. Traffic control expense for undertaking the repairs will be at the Contractor's expense.

Precautions should be taken to ensure that the tapping saddle or sleeve is placed on the pipe straight to pre-
vent any binding or deformation of the PVC pipe. The mounting chain or U -bolt strap must be tight.
Tapping shall be performed with a sharp shell type cutter so designed that ft will smoothly penetrate heavy
walled PVC DR14 and 200 psi AC and will retain and extract the coupon from the pipe.
(25) Backfilling
(a) General
Atter the pipe has been bedded, laid, Jointed, approved and any bedding envelope placed, backfilling shall be
done immediately in accordance with the details indicated, with approved material, except that when mortar
Joints are used for (ointing storm sewers, no backfill above the bedding shall be placed, until the mortar has
cured for at least 6 hours.
During backfilling operations, no heavy equipment which might damage the pipe will be allowed until a mini-
mum cover of 12 inches above the top of pipe is obtained.
During the backfilling operations, special emphasis is placed upon the need for obtaining uniform backfill ma-
terial and uniform compacted density throughout the length and depth of the structure. Extreme care is to be
taken to insure proper backfill over the pipe. The maximum lift of backfill shall be determined by the equipment
selected and in no case shall it exceed 18 Inches, loose measurement.
All backfill in streets and under structures will be tested by the City and must satisfy the specified density
requirements conforming to Section 00344, "Testing Laboratory Services" before final acceptance.
(b) General Corrugated Metal Pipe
After the corrugated metal pipe structure has been completely assembled on the proper line and grade and
headwalls constructed when indicated, selected material free from rocks over 8 inches in size from excavation
or borrow, as approved by the Engineer, shall be placed along both sides of the completed structures equally,
in uniform layers not exceeding 6 inches in depth (loose measurement), sprinkled if required and thoroughly
compacted between adjacent structures and between the structures and the sides of the trench or for a dis-
tance each side of the structures equal to the diameter of the pipe if pipe is laid above the existing ground.
Backfill material shall be compacted to the same density requirements as indicated for the adjoining sections
of embankment In accordance with the governing specifications thereof. Above the W. point of the structure,
the fill shall be placed uniformly on each side of the pipe in layers not to exceed 12 inches, loose measure.
Prior to adding each new layer of loose backfill material, until a minimum of 12 inches of cover is obtained over
the crown of the pipe, an inspection will be made of the inside periphery of the corrugated metal structure
to determine if any floating, local or unequal deformation has occurred as a result of improper construction
methods.
(c) Backfill Materials
The Engineer may approve any of the following well graded materials:
1. Select trench material
2. Sand
3. Crushed rock cuttings
4. Rock cuttings
5. Foundation Rock
6. Blasted material with fines and rock
7. Cement stabilized material
8. Borrow
Within the 100 year flood plan sand will not be permitted for bedding or backfilling. The Engineer shall approve
the topsoil for areas to be seeded or sodded.
(d) Backfill in Street Right of Way
Placement of backfill under structures and within 2 feet of structures shall be compacted to the required den-
sity using any method, type and size of equipment which will give the required compaction without damaging
Page 31 04;17/86 ; 510
the pipe or bedding. The depth of layers, prior to compaction, shall depend upon the type of sprinkling and
compacting equipment used and the test results thereby obtained. Prior to and in conjunction with the com-
paction operation, each layer shall be brought to the moisture content necessary to obtain the required density
and shall be kept leveled to insure uniform compaction over the entire layer. Testing for density will be in accor-
dance with Test Method Tex -114 -E and Test Method Tex - 115 -E.
Each layer of backfill must provide the density as required herein. Swelling soils (soils with plasticity index
of 20 or more) shall be sprinkled as required to provide not less than optimum moisture nor more than 2 per-
cent over optimum moisture content and compacted to the extent necessary to provide not less than 95 per-
cent nor more than 102 percent of the density as determined In accordance with Test Method Tex - 114 -E.
Nonswelling soils (soils with plasticity index less than 20) shall be sprinkled as required and compacted to the
extent necessary to provide not less than 95 percent of the density as determined in accordance will Test
Method Tex - 114 -E.
After each layer of backfill is complete, tests may be made by the Engineer. If the material fails to .meet the
density indicated, the course shall be reworked as necessary to obtain the indicated compaction and the com-
paction method shall be altered on subsequent work to obtain Indicated density and conform to Section 00344,
"Testing Laboratory Services ".
At any time, the Engineer may order proof rolling to test the uniformity of compaction of the backfill layers. All
Irregularities, depressions, weak or soft spots which develop shall be corrected immediately by the Contractor.
Should the backfill, due to any reason or cause, lose the required stability, density or finish before the pave-
ment structure is placed, it shall be recompacted and refinished at the sole expense of the Contractor. Exces-
sive loss of moisture in the subgrade shall be prevented by sprinkling, sealing or covering with a subsequent
backfill layer or granular material. Excessive loss of moisture shall be construed to exist when the subgrade
soil moisture content is more than 4 percent below the optimum of compaction ratio density. Backfill shall be
placed from the top of the bedding material to the existing grade, base course, subgrade or as indicated. The
remainder of the street backfill shall be Flexible Base, Concrete or Hot Mix Asphalt Concrete as indicated or to
replace in kind the surface removed to construct the pipe.
(e) Backhll in County Street or State Highway Right of Way
All work within the right of way must meet the requirements of (d) above, as a minimum anc shall meet the
requirements of the permit issued by the County when their requirement are more stringent. F'rior to the start
of construction, the Contractor will be responsible for contacting the appropriate SDHPT office or County
Commissioner's Precinct Office and for coordinating his activities with the operating procedu es in effect for
utility cut permits and pavement repair under their jurisdiction. Approval for all completed wort in the State or
County right of way must be obtained from the appropriate Official prior to final payment by the Owner.
(f)

Backfill in Railroad Right of Way
All work within the railroad right of way must meet the requirements of (d) above, as a minimum and shall meet
the requirements of the permit issued by the Railroad Owner when their requirements are more stringent.
Approval for all completed work in the railroad right of way must be obtained from the Railroad prior to final
acceptance.
Backfill in Easements
Where not otherwise indicated, all backfill in easements across dedicated parkways, planting spaces, under or
adjacent to utilities, structures, etc., shall satisfy all the requirements for backfill in streets or under structures.
Where there are no requirements for density, the Contractor may select whatever methods and procedures
may be necessary to restore the entire work area to a safe, useful and geologically stable condition satisfac-
tory to the Engineer and generally equal or superior to the conditions prior to construction.
In and near the flood plain of all streams and watercourses and on all slopes subject to erosion by eunoff, all
backfill shall be compacted to at least 95 percent of maximum dry density as for street right of way, unless
otherwise directed by the Engineer.
All soil areas disturbed by the construction shall be covered with top soil and seeded conforming to Item No.
604, "Seeding for Erosion Control ". All turf, drainways and drainage structures shall be constructed or re-
placed to their original condition or better. No debris shall remain in the drainways or drainage structures.
(26) Quality Testing for Installed Pipe
(a) Wastewater Pipe Acceptance Testing

Wastewater pipe installed in the City of Austin and its ETJ areas shall be tested for exfiltration and infiltration
as described below in "Exfiltration Test" and "Infiltration Test" or by acceptable low pressure air test, as de-
scribed below. At the conclusion of either test series, the work shall be further tested for pipeline settlement as
described below. The Contractor shall be solely responsible for making proper structural repairs to those ele-
ments which do not pass these test requirements.
(b) Exfiltration Test
The pipeline shall be completely filled with water for its complete length or by sections as determined by the
Engineer. If tested for its complete length, the maximum head at any point shall not exceed 25 feet unless
otherwise indicated. 11 tested in sections, the manholes in the test section shall be completely filled with water.
After the pipeline has been filled and allowed to stand for 24 hours, the amount of exfiltration shall be calcu-
lated. Any amount in excess of 200 gallons per inch of inside pipe diameter per mile per day shall be cause for
rejection.
• (c) Infiltration Test
When the pipe placed in easements Is completed, the upper portion of the ditch backfill shall be removed to a
depth of not less Than 18 inches below the finished surface and width equal to the original trench width. The
trench shall then be flooded with water until it is completely saturated and water stands in the ditch a minimum
of 12 inches deep. In cases of steep terrain, earthen dikes shall be used to assure that water will stand over
the trench. After it is apparent that the trench is completely saturated, the main shall then be inspected with
closed•circuit television for infiltration. Any section of the main or any service stub that indicates excessive
infiltration shall be cause for rejection.
This procedure shall not be used for pipes installed in areas where the P.I. of the surrounding material is 20 or
higher or where the backfill material has a P.I. of 20 or more.
(d) Pipeline Settlement Test
During the infiltration test or after the exfiltration test, the pipe will be TV inspected for possible settlement.
When air testing has been used, water shall be flowed into the pipe to permit meaningful observations. Any
pipe settlement which causes excessive ponding of water in the pipe shall be cause for rejection.
(e) Low Pressure Air Test of Gravity Flow Wastewater Lines
(1) General
Wastewater lines in sizes for which the City has testing equipment may, at the discretion of the Engineer.
be air tested between manholes. Backfilting to grade shall be completed before the test and all laterals
and stubs shall be capped or plugged by the Contractor so as not to allow air losses which could cause
an erroneous test result. Manholes are to be plugged so they are isolated from the pipe and cannot be
included in the test.
All plugs used to close the sewer for the air test must be capable of resisting the internal pressures and
must be securely braced. Place all air testing equipment above ground and allow no one to enter a
manhole or trench where a plugged sewer is under pressure. Release all pressure before the plugs are
removed. The testing equipment used must include a pressure relief device designed to relieve pressure
in the sewer under test at 10 psi or less and must allow continuous monitoring of the test pressures in
order to avoid excessive pressure. Use care to avoid the flooding of the air inlet by infiltrated ground
water. (Inject the air at the upper plug it possible.) Use only qualified personnel to conduct the test.
(2) Ground Water
Since the presence of ground water will affect the test results, test holes shall be dug to the pipe zone at
intervals of not more than 100 feet and the average height of ground water above the pipe (if any) shall
be determined before starting the test. -
(3) Test Procedure
The Engineer may, at any time, require a calibration check of the instrumentation used. Use a pressure
gauge having minimum divisions of 0.10 psi and an accuracy of 0.0625 psi. (One ounce pet square
inch.) All air used shall pass through a single control panel. Clean the sewer to be tested and remove all
debris where indicated. Wet the sewer prior to testing. The average back pressure of any groundwater
shall be determined (0.433 psi) for each tool of average water depth (if any) above the sewer.
Add air slowly to the section of sewer being tested until the internal air pressure is raised to 4 0 psig
greater than the average back pressure of any ground water that may submerge the pipe.
Page 33 04,17186 510
(27) Pressure Pipe Hydrostatic Testing
After the pipe has been installed and backfilled and all service laterals, fire hydrants and other appurtenances in-
stalled and connected, a leakage test, followed by a pressure test, will be conducted by the City. The City will furnish
the pump and gauges for the tests. The Contractor will be present and shall furnish all necessary assistance for
conducting the tests. The specified test pressures will be based on the elevation of the lowest point of the line or
section under test. Before applying the specified test pressure. all air shall be expelled from the pipe. If permanent air
vents are not located at all high points, the Contractor shall Install corporation cocks at such points.
(a) Pressure Test
The entire project or each valved section shall be tested, at a pressure of 200 psi for a sufficient period (ap-
proximately 10 minutes) to discover all leaking or defective materials. Repairs shal be made by the Contractor
to correct any leaking or defective materials.
(h) Pressure Pipe Leakage Test
A leakage test will follow the pressure test and be conducted on the entire project or such valved section. The
leakage test shall be at 150 psi for at least 1 hour.
(1) Allowable Leakage
Leakage shall be defined as the quantity of water that must be supplied into any test section of pipe to
maintain the specified leakage test pressure (see above, "Pressure Pipe Leakage Test ") after the air in
the pipeline has been expelled and the pipe has been filled with water. The allowable leakage shall com-
ply with AWWA C -600 which defines the allowable leakage as:
(28) Service Charges for Testing
No charge will be made to the Contractor for the City's test equipment, inspection, etc., when the test results show
that leakage is within the indicated allowable limits.
For each test, either for leakage or for pressure, which fails to meet the indicated requirements, the City's flat charge
of $50.00 for such tests will be charged to the Contractor and will be deducted from any funds due the Contractor.
510 04/17/86 Page 34
After the internal test pressure is reached, allow at least 2 minutes for the air temperature to stabilize.
adding only the amount of air required to maintain pressure. After the temperature stabilization period.
disconnect the air supply.
Determine and record the time in seconds that is required for the intemal air pressure to drop from 3.5
psig to 2.5 psig greater than the average back pressure of any ground water that may submerge the
pipe.
Compare the time recorded with the time required as follows:
Pipe Size (Inches) 6 8 10 12 15 18 21 24
Time (Minutes) 3 4 5 6 7.5 9 10.5 12
Any drop in pressure, from 3.5 psig to 2.5 psig, in a time less than that required by the above table shall
be cause for rejection. When the line tested includes more than one size pipe, the minimum time shall
be that given for the largest size pipe included.
When lines are air tested, manholes are to be tested separately by exfiltration or infiltration.
L_ SD P
133 200
where L = Leakage in gallons per hour
S = Length of pipe in feet
D = Diameter (inside) of pipe in inches
P = Pressure in pounds per square inch
If such testing discloses leakage In excess of this specified allowable, the Contractor, at nis expense,
shall locate and correct all defects In the pipeline until the leakage is within the indicated allowance.

(29) Sterilization of Potable Water Lines
The Contractor shall protect all piping materials from contamination dunng storage, handling and installation. Prior to
disinfection, the pipeline interior shall be clean, dry and unobstructed. All dirt, debris, gasket lubricant, etc., shall be
washed from the line by swabbing with hypochlorite solution and /or flushing with clean water.
The City, at its expense, will supply the test gauges and the concentrated disinfecting material and City personnel
will supervise and direct the overall sterilization procedure. The Contractor, at his expense, shall provide all other
equipment, supplies and the necessary labor to perform the sterilization under general supervision of the City.
(a) Procedure and Dosage
All valves shall be arranged to prevent the strong disinfecting dosage from flowing back into the existing water
supply piping. The new pipeline shall then be completely filled with disinfecting solution by feeding the concen-
trated chlorine and approved water from the existing system uniformly into the new piping in such proportions
that every part of the line has minimum concentration of 50 parts per million (50 ppm or 50 mg/liter) available
chlorine.
Unless otherwise indicated, all quantities called for herein refer to measurements by the testing procedures in
the current edition of "Standard Methods ". The chlorine concentration of each step in the sterilization proce-
dure shall be verified by chlorine residual determinations. This disinfecting solution shall be retained in the
piping for at least 24 hours and all valves, hydrants, etc., shall be operated 10 disinfect all their parts. Alter this
retention period, the water shall contain no less than 25 parts per million chlorine throughout the treated sec-
tion of the pipeline.
This heavily chlorinated water shall then be carefully flushed from the line until the chlorine concentration is no
higher than the residual generally prevailing in the existing distribution system or approximately one part per
million. Proper planning and appropriate preparations to handle. dilute and dispose of this strong chlorine solu-
tion without causing injury or damage to the public, the water system or the environment must be approved by
the City before flushing of the line may begin and the flushing shall be witnessed by an authorized represen-
tative of the City.
(b) Bacteriological Testing
After final flushing of the strong disinfecting solution, water samples from the line shall be tested for bac-
teriological quality by the City and must be found free of coliform organisms before the pipeline may be placed
