1.06 Work
gencond.msr/spec

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 new and both

1.07 Extra Work
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.

GC -5
2. Responsibilities of the Engineer and the Contractor
2.01 Owner - Engineer Relationship
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
gencond.msispec
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
gencond.mstispec
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 (1 0)
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
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 employees
GC -7
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
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 verbal agreement or conversation with any
gencond_msr/spec
GC -8
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
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
gencond.rnslispec
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 he the
Contractor's responsibility to fully and completely review all shop drawings to ascertain their
effect on his ability to perform the required contract work in accordance with the plans and
GC -9
se0000d.msuspeo
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 shall
be in full accordance with this contract.
GC -10
2.15 Changes and Alterations
gencond.msUspec
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 he 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 extent,
nature, manner and performance of the work so that the Engineer may more effectively
perform his duties hereunder. Such inspectors may also communicate between Engineer and
Contractor their respective reports, opinions, questions, answers and clarifications
concerning the plans, specifications and work but shall not be deemed the agent of the
Contractor for all purposes in communicating such matters.
Such inspector may confer with the Contractor or Contractor's superintendent concerning the

the preceding month. The statement shall also include the value of all sound materials
delivered on the job site and to be included in the work and all partially completed work
whether bid as a lump sum or a unit item which in the opinion of the Engineer is acceptable.
The Engineer shall examine and approve or modify and approve such statement.
The Owner shall then pay the Contractor on or before the 20th day of the current month the
total amount of the approved statement, less 10 percent of the amount thereof, which 10
percent shall be retained until final payment, and further less all previous payments and all
further sums that may by retained by the Owner under the tenns of this Agreement. It is
understood, however, that in case the whole work be near to completion and some unexpected
and unusual delay occurs due to no fault or neglect on the part of the Contractor, and Owner
may - upon written recommendation of the Engineer - pay a reasonable and equitable portion
of the retained percentage to the Contractor; or the Contractor at the Owner's option, may be
relieved of the obligation to fully complete the work and, thereupon, the Contractor shall
receive payment of the balance due him under the contract subject only to the conditions stated
under "Final Payment ".
5.05 Use of Completed Portions
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 or
such portions may not have expired but such taking possession and use shall not be deemed
an acceptance of any work not completed in accordance with the Contract Documents. If such
prior use increases the cost of or delays the work, the Contractor shall be entitled to such extra
compensation, or extension of time, or both, as the 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 furnish to
the Engineer in writing a detailed list of unfinished work. The Engineer will review the
Contractor's list of unfinished work and will add thereto such items as the Contractor has
failed to include. The "substantial completion" of the structure or facility shall not excuse the
Contractor from performing all of the work undertaken, whether of a minor or major nature,
and thereby completing the structure or facility in accordance with the Contract Documents.
GC -26
5.06 Final Completion and Acceptance
Within ten (10) days after the Contractor has given the Engineer written notice that the work
has been completed, or substantially completed, the Engineer and the Owner shall inspect the
work and within said time, if the work be found to be completed in accordance with the
Contact Documents, the Engineer shall issue to the Owner and the Contractor his Certificate
of Completion, and thereupon it shall be the duty of the Owner to issue a Certificate of
Acceptance of the work to the Contractor or to advise the Contractor in writing of the reason
for non - acceptance.
5.07 Final Payment
Upon the issuance of the Certificate of Completion, the Engineer shall proceed to make final
measurements and prepare final statement for the value of all work perfonned and materials
furnished under the terms of the Agreement and shall certify same to the Owner, who shall pay
to the Contractor on or before the 30th day, and before the 35th day, after the date of the
Certificate of Completion, the balance due the Contractor under the terns of this contract; and
said payment shall become due in any event upon said performance by the Contractor. Neither
the Certificate of Acceptance nor the final payment, nor any provision in the Contract
Documents, shall relieve the Contractor of the obligation for fulfillment of any warranty which
may be required.
5.08 Payments Withheld
gencond_msYspec
The Owner may, on account of subsequently discovered evidence, withhold or nullify the
whole or part of any certificate to such extent as may be necessary to protect himself from loss
on account of:
a) Defective work not remedied or other obligations hereunder not done.
b) Claims filed or reasonable evidence indicating probable filing of claims.
c) Failure of the Contractor to make payments properly to subcontractors or for material
or labor.
d) Damage to the Owner or another contractor's work, material or equipment.
e) Reasonable doubt that the work can be completed for the unpaid balance of the
contract amount.
f) Reasonable indication that the work will not completed within the contract time
g) Other causes affecting the performance of the contract.
GC -27
When the above grounds are removed or the Contractor provides a Surety Bond satisfactory
to the Owner, which will protect the Owner in the amount withheld, payment shall he made
for amounts withheld because of them.
5.09 Delayed Payments
Should the Owner fail to make payment to the Contractor of the sum named in any partial or
final statement, when payment is due, then the Owner shall pay to the Contractor, in addition
to the sum shown as due by such statement, interest thereon at the rate of 6% per annum,
unless otherwise specified, from date due as provided under 'partial payments' and final
'payments,' until fully paid, which shall fully liquidate any injury to the Contractor growing
out of such delay in payment. It is expressly agreed that delay by the Owner in making
payment to the Contractor of the sum named in any partial or final statement shall not
constitute a breach of this contract on the part of the Owner nor an abandonment thereof nor
shall it to any extent or for any time relieve the Contractor of his obligations to fully and
completely perform hereunder.
6. Extra Work and Claims
6.01 Change Orders
Without invalidating this Agreement, the Owner may, at any time or from time to time, order
additions, deletions or revisions to the work; such changes will be authorized by Change Order
to be prepared by the Engineer for execution by the Owner and the Contractor. The Change
Order shall set forth the basis for any change in contract price, as hereinafter set forth for Extra
Work, and any change in contract time which may result from the change.
In the event the Contractor shall refuse to execute a Change Order which has been prepared
by the Engineer and executed by the Owner, The Engineer may in writing instruct the
Contractor to proceed with the work as set forth in the Change Order and the Contractor may
make claim against the Owner for Extra Work involved therein, as hereinafter provided.
6.02 Minor Changes
gencond
The Engineer may authorize minor changes in the work not inconsistent with the overall intent
of the Contract Documents and not involving an increase in Contract Price. If the Contractor
believes that any minor change or alteration authorized by the Engineer involves Extra Work
and entitles him to an increase in the Contract Price, the Contractor shall make written request
to the Engineer for a written Field Order.
GC -28
gencond.msUspee
In such case, the Contractor by copy of his communication to the Engineer or otherwise in
writing shall advise the Owner of his request to the Engineer for a written Field Order and that
work involved may result in an increase in the Contract Price.
Any request by the Contractor for a change in Contract Price shall he made prior to beginning
the work covered by the proposed change.
6.03 Extra Work
It is agreed that the basis of compensation to the Contractor for work either added or deleted
by a Change Order or for which a claim for Extra Work is made shall be determined by the
unit prices upon which this contract was bid to the extent such work can be fairly classified
within the various work item descriptions and for work items that cannot be so classified by
one or more of the following methods:
Method (A)
By agreed unit prices; or
Method (B)
By agreed lump sum; or
Method (C)
If neither Method (A) nor Method (B) be agreed upon before the Extra Work
is commenced, then the Contractor shall be paid the "actual field cost" of the
work, plus fifteen (15) percent.
In the event said Extra Work be performed and paid for under Method (C), then the provisions
of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost
to the Contractor of all workmen, such as foreman, timekeepers, mechanics and laborers, and
materials, supplies, trucks, rentals on machinery and equipment, for the time actually
employed or used on such Extra Work, plus actual equipment, for the time actually employed
or used on such Extra Work, plus actual transportation charges necessarily incurred, together
with all power, fuel, lubricants, water and similar operating expenses, also all necessary
incidental expenses incurred directly on account of such Extra Work, including Social
Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of premiums on
Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property
Damage and Workmen's Compensation, and all other insurance as may be required by any lays
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 specie.
GC -29
gencond.msutpec
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 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.
All questions of dispute under this Agreement shall he 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 fad to select a third within ten (10) days, he shall be chosen by a
Distract 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.
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 an

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
GC -32
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 terns 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 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 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 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

such Certificate of Completion.
In case the Owner shall fail to comply with the terns of this contract, and should fail to
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 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 terns of this Agreement and
shall certify same to the 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 tenns of this Agreement.

Contractor, as soon as practicable after the award of the Contract, shall furnish to the Engineer
in writing for acceptance by the Owner and the Engineer a list of the names of 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 Documents
or the Instructions to Bidders, the Contractor shall submit an acceptable substitute and the
Contract amount shall be increased or decreased by the difference in cost occasioned by such
substitution and an appropriate change order shall be issued; however, no increase in the
Contract amount shall be allowed for any such substitution 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
GC -34
written agreement between the Contractor and the Subcontractor (and where appropriate
between Subcontractors and Sub - subcontractors) which shall contain provisions that
(1) preserve and protect the rights of the Owner and Engineer under the Contract
with respect to the work to he performed under the subcontract so that the
subcontracting thereof will not prejudice such rights;
(2) require that such work be performed in accordance with the requirements of
the Contract Documents;
(3) require submission to the Contractor of the applications for payment under
each subcontract to which the Contractor is a party, in reasonable time to
enable the Contractor to apply for payment in accordance with this contract;
(4) require that all claims for additional costs, extensions of time, damages for
delays or otherwise with respect to subcontracted portions of the work shall be
submitted to the Contractor (via any Subcontractor or Sub- subcontractor where
appropriate) in sufficient time so that the Contractor may comply in the manner
provided in the Contract Documents for like claims by the Contractor upon the
Owner;
(5) obligate each subcontractor specifically to consent to the provisions of this
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
sencond.msr/spee
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 payment
of any moneys to such Subcontractor except as may otherwise be required.

If any part of the Contractor's work depends for proper execution or results upon 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 proceedings at the Contractor's expense, and
if any judgment or award against the Owner 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.

Precautions should be taken to ensure that the tapping saddle or sleeve is placed on the pipe straight to prevent 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 it 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
Special emphasis is placed upon the need to obtain uniform density throughout the backfilt material. The maximum
lift of backfill shall be determined by the compaction equipment selected and in no case shall it exceed 18 inches,
loose measurement.
No heavy equipment, which might damage pipe, will be allowed over the pipe until sufficient cover has been placed
and compacted. All intemal pipe bracing installed or recommended by the manufacturer shall be kept in place until
the pipe bedding and trench backfill have been completed over the braced pipe section. Testing of the completed
backfill in streets and under and around structures shall meet the specified density requirements. Initial testing shall
not be at Contractors expense and shall conform to Section 00344, "Testing Laboratory Services.'
(b) General Corrugated Metal Pipe
After the corrugated metal pipe structure has been completely assembled on (he proper line and grade and
headwalls constructed where 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.
Backfill material shall be compacted to the same density requirements as indicated for the adjoining sections of
embankment in accordance with the goveming specifications thereof. Above the 3/4 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.

compacting equipment used and the test results thereby obtained. Prior to and in conjunction with the compaction
operation, each layer shall be brought to the moisture content necessary to obtain the required density and shall be
kept level to insure uniform compaction over the entire layer_ Testing for density shall he in accordance 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 percent over
optimum moisture content and compacted to the extent necessary to provide not less than 95 percent nor more than
102 percent of the density as determined in accordance with Test Method Tex-174-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 with 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 compaction method
shall be altered on subsequent work 10 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, lose the required stability, density or finish before the pavement structure is
placed, it shall be recompacted and refinished at the sole expense of the Contractor. Excessive 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 replaced in kind to the surface removed to
construct the pipe.
(e) Backfill in County Street or State Highway Right of Way
All work within the right of way shall meet the requirements of (d) above, as a minimum and shall meet the
requirements of the pen issued by the County when their requirements are more stringent. Prior to the start of
construction, the Contractor shall be responsible for contacting the appropriate TXDOT office or County
Commissioners Precinct Office and for coordinating his activities with the operating procedures in effect for utility cut
permits and pavement repair under their jurisdiction. Approval for all completed work in the State or County right of
way shall be obtained from the appropriate Official prior to final payment by the Owner,
(f) Backfill in Railroad Right of Way

(g) Backlit! in Easements
Where not otherwise indicated, Contractor may select whatever methods and procedures may be necessary to
restore entire work area to a safe, useful and geologically stable condition with a minimum density of 85 percent or a
density superior to that prior to construction.
In and near flood plain of all streams and watercourses, under or adjacent to utilities, structures, etc., all backfill shall
be compacted to a density of not less than 95 percent conforming to TXDOT Test Method Tex- 114.E, unless
otherwise directed by Engineer.
All soil areas disturbed by 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 replaced 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
After construction is complete, Engineer will determine whether the pipeline is to be tested for infiltration, exfdtrat:on
or by the low pressure air test method. In addition, plastic pipe 18 inches and larger in diameter shall be deflection
tested.
02/17/94 Page 35 Pipe
510
Wastewater pipe installed in the City of Austin and its ETJ areas shall be tested for exfiltration or infiltration as
described below in "Exfiltration Test" and "Infiltration Test" or by acceptable low pressure air test, as described
below. At the conclusion of either test series, the work shall be further tested for pipeline settlement and also for
deflection as described below. The Contractor shall be solely responsible for making proper repairs to those
elements which do not pass these test requirements.
(b) Exfiltration Test
The pipeline shall be completely filled with wafer tor 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. If 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 calculated. Any amount
in excess of 200 gallons per inch of inside pipe diameter per mile per day shall be cause for rejection.
For portions of lines located within the Edwards Aquifer Recharge Zone or within any recharge area or recharge
feature within the Edwards Aquifer Transition Zone, the minimum head during testing shall not be less than 2 feet
and the leakage rate shall not exceed 50 gallons per inch of inside pipe diameter per mile per day. This rate shall
apply for the entire portion of the line extending up to the first manhole located outside the recharge zone, recharge
area, or recharge features indicated on plans and shall also be applicable for any recharge areas or recharge
features which may be identified during construction. For construction within the 25 year flood plain, the exfiltration
rate shall not exceed 10 gallons per inch diameter per mile of pipe per 24 hours al the same minimum test head.
(c) Infiltration Test
When the pipe placed in easements is completed, the upper portion of the trench backf ill 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 0112 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 Plasticity Index (P.I.) of the surrounding
material is 20 or higher or where the backfill material has a P.I. of 20 or more
For portions of lines located within the Edwards Aquifer Recharge Zone or within any recharge area or recharge
feature within the Edwards Aquifer Transition Zone, the total infiltration as determined by water test, must be at a
rate not greater than 50 gallons per inch of pipe diameter per mile of pipe per 24 hours at a minimum test head of
two feet. This rate shall apply for the entire portion of the line extending up to the first manhole located outside the
recharge zone, recharge area, or recharge features indicated on plans and shall also be applicable for any recharge
areas or recharge features which may be identified during construction. For construction within the 25 year flood
plain, the infiltration rate shall not exceed 10 gallons per inch diameter per mile of pipe per 24 hours at the same
minimum test head.
If the quantity of infiltration exceeds the maximum quantity specified, remedial action must be undertaken in order to
reduce the infiltration to an amount within the limits specified.
(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 Plastic Gravity Flow Wastewater Lines
(1) General
Wastewater lines, at the discretion of the Engineer, shall be air tested between manholes. Backfilling 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 shall 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 shall 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 trenar
where a plugged sewer is under pressure. Release all pressure before the plugs are removed, The test -^
equipment used must include a pressure relief device designed to relieve pressure in the sewer under tes a•. -'
psi or less and must allow continuous monitoring of the test pressures in order to avoid excessive pressure - -

Use only qualified personnel to conduct the test.
(2) Ground Water
Since the presence of ground water wit affect the test res
of not more than 100 feel and the average height of gro
before starting the test.
(3) Test Procedure
The Engineer may, al 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 per square inch.) All air used
shall pass through a single control panel. Clean the sewer to be tested and remove at debris where indicated.
Wet the sewer prior to testing. The average back pressure of any groundwater shall be determined (0.433 psi)
for each fool 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.
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 internal 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: specification time for the size and length of pipe as given in the following

Test procedure for wastewater pipe located in the Edwards Aquifer Recharge Zone or identified recharge areas
or recharge features within the Edwards Aquifer Transition Zone:
Low - pressure air tests must conform to the procedure described in ASTM C -924 or other equivalent procedures.
For safety reasons. air testing of pipe sections will be limited to line sizes of 36 inches inside diameter or less.
Lines that are 36 inches or larger inside diameter may be air tested at each joint. The minimum time allowable
for the pressure to drop from 3.5 pounds per square inch to 2,5 pounds per square inch gauge during a joint test,
regardless of pipe size, shall be twenty (20) seconds.
For sections of pipe less than 36 -inch inside diameter, the minimum time allowable for the pressure to drop from
3.5 pounds per square inch gauge to 2.5 pounds per square inch gauge must be computed by the following
equation:
T = 0.0850 (D)(K) /(Q), where
T = time for pressure to drop 1.0 pounds per square inch gauge in seconds;
K = 0.000419(D)(L), but not less than 1.0
D = nominal inside diameter in inches;
L = length of line of same pipe size in feet; and
Q = rate of loss, assume 0.0015 cubic feet per minute per square foot (ft /min/ft sq) of internal surface
area
Any drop in pressure, from 3.5 psig to 2.5 psig, in a time less than that required by the above formula shall be
cause for rejection. When the line tested includes more than one size of pipe, the minimum time shall be that
calculated for the largest size pipe included,
Manholes must be tested separately and independently. All manholes must be hydrostatically tested with a
maximum loss allowance of 0.025 gallon per foot diameter per foot of head per hour.
When lines are air tested, manholes are to be tested separately by exfiltration or. vacuum method (see Item 506,
Manholes).
(f) Deflection Test
Deflection tests shall be performed by the Contractor on all flexible and semi -rigid wastewater pipes. The tests shall
be conducted after the final backfill has been in place at least 30 days. Testing for in -place deflection shall be with a
pipe mandrel or rigid ball sized at 95% of the inside diameter of the pipe. A second test of flexible and semi -rigid
wastewater pipes 18 inch size and larger, also with a pipe mandrel or ball sized at 95% of the inside diameter of the
pipe, shall be conducted by the Contractor 30 days prior to expiration of his warranty on the work.
Contractor shall submit his proposed pipe mandrels or testing bats to the Engineer or his designated representative
for concurrence prior to testing the line.
Test(s) must be performed without mechanical pulling devices and must be witnessed by the Engineer or his
designated representative.
Any deficiencies noted shall be corrected by the Contractor and the test(s) shall be redone.
(27) Pressure Pipe Hydrostatic Testing
After the pipe has been installed and backfilled and all service laterals, fire hydrants and other appurtenances installed
and connected, a pressure test, followed by a leakage test, wit be conducted by the City. The City will furnish the pump
and gauges for the tests. The Contractor shall 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.
All drain hydrant and fire hydrant leads, with the main 6 -inch gate valve open, the hydrant valve seats closed and nozzle
caps open, shall be included in the lest.
(a) Pressure Test
The entire project or each valved section shall be tested, at a pressure of 200 psi for a sufficient period
(approximately 10 minutes) to discover all leaking or defective materials. Repairs shall be made by the
Contractor to correct any leaking or defective materials.
510 02/17/94
Page 38 a, F

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.
No pipe installation will be accepted if the leakage exceeds 25 gallons /24 hours /mile of pipe /inch nominal
pipe diameter.
( 25 gpd 1
(in. - mi.)
(2) Location and Correction of Leakage
If such testing discloses leakage in excess of this specified allowable, the Contractor, at his expense,_shall
locate and correct all defects in the pipe line until the leakage is within the indicated allowance.
All visible leakage in pipe shall also be corrected by Contractor at his own expense.
(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.
(29) Sterilization of Potable Water Lines
The Contractor shall protect all piping materials from contamination during storage, handling and installation. Prior to

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
concentrated 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 procedure
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 to disinfect all their parts. After this retention
period, the water shall contain no less than 25 parts per million chlorine throughout the treated section of the
pipeline.
This heavily chlorinated water shall then be carefully flushed from the line until the chlorine concentration is ea
higher than the residual generally prevailing in the existing distribution system or approximately one part pe
million. Proper planning and appropriate preparations to handle, dilute and dispose of this strong chlorir_
solution without causing injury or damage to the public, the water system or the environment must be approve:
by the City before flushing of the line may begin and the flushing will be witnessed by an authorize:
representative of the City.
02/17/94 Page 39 Pipe
(b) Bacteriological Testing
Atter final flushing of the strong disinfecting solution, water samples from the line will be tested for bacteriological
quality by the City and must be found free of coliform organisms before the pipeline may be placed in service.
One lest sample will be drawn from the end of the main and additional samples collected at intervals 0 not more
than 1000 feel along the pipeline.
The Contractor, at his expense, shall install sufficient sampling taps at proper locations along the pipeline. Each
sampling tap shall consist 0 a standard corporation cock installed in the line and extended with a copper tubing
gooseneck assembly. After samples have been collected, the gooseneck assembly may be removed and
retained for future use.
Samples for bacteriological analysis will be collected only from suitable sampling taps in sterile bottles treated
with sodium thiosulfate. Samples shall not be drawn from hoses, fire hydrants, etc. The City, at its expense, will
furnish the sterile sample bottles and may, at its discretion, collect the test samples with City personnel.
If the initial disinfection fails to produce acceptable sample tests, the disinfection procedure shall be repeated
(without extra compensation) until satisfactory test results have been obtained before the piping may be placed in
service.
(30) Cleanup and Restoration
It shall be the Contractor's responsibility to keep the construction site neat, clean and orderly at all times.
Cleanup shall be vigorous and continuous to minimize traffic hazards or obstructions along the streets and to driveways.
Trenching, backfill, pavement repair (as necessary), and cleanup shall be coordinated as directed by the City. The
Engineer will regulate the amount of open ditch and may halt additional trenching if cleanup is not adequate to allow for
orderly traffic flow and access.
Materials at the site shall be stored in a neat and orderly manner so as not to obstruct pedestrian or vehicular traffic. All
damaged material shall be removed from the construction site immediately and disposed of in a proper manner. All
surplus excavated materials become the property of the Contractor for disposal at his expense. After trenching, the
Contractor shall immediately remove all excavated materials unsuitable for or in excess of, backfill requirements.
Immediately following the pipe laying work as it progresses, the Contractor shall backfill, grade and compact all
excavations as provided elsewhere and shall immediately clean up and remove all unused soil, waste and debris and
restore all surfaces and improvements to a condition equal or superior to that before construction began and to an
appearance which complements the surroundings. The Contractor shall grade and dress the top 6 inches of earth
surfaces with soil or other material similar and equal to the surrounding, fill and smooth any visible tracks or ruts, replace
and re- establish all damaged or disturbed turf or other vegetation and otherwise make every effort to encourage the
retum of the entire surface and all improvements to a pleasant appearance and useful condition appropriate and
complementary to the surroundings and equal or similar to that before construction began.
Permanent pavement replacement, if necessary, shall begin immediately after all testing of each segment of piping is
satisfactorily completed.

DATE: February 18, 1998
SUBJECT: City Council Meeting, February 26, 1998
ITEM: 10C. Consider a resolution authorizing the Mayor to execute
an agreement with Garney Companies, Inc. for a 30 -inch
treated water bypass at the Water Treatment Plant.
STAFF RESOURCE PERSON: Jim Nuse
STAFF RECOMMENDATION:
Late last fall, a deficiency was discovered in the water distribution system at the
water plant. A bypass is needed in order to deliver water reliably. This bypass is
a specialty project consisting of large pipe and valve installation tying into an
existing 42" line. The existing line is concrete steel cylinder pipe material and
requires skill in constructing.
Garney Companies, Inc. is one of a very few contractors in the state able to
accomplish this type of work. It is critical that the bypass be installed by the
spring to ensure the reliable delivery of water to the customers. Garney built the
parallel raw water line from Lake Georgetown a few years ago and gave us an
excellent project.
Staff recommends, under the health and safety provision of the bidding statues,
awarding Garney Companies, Inc. the project to install this bypass as soon as
possible. The contract amount is $181,700.00 and this work can be
accomplished in approximately 60 days. Staff recommends approval.
