judgment that the work has progressed to the poir;t indicated to the best of his knowledge, information
and belief, but such approval of an application for payment to Contractor shall not be deemed as a repre-
sentation 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.
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 days, appeal to arbitration may be taken as if his deci-
sion had been rendered against the party appealing.

thirty 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

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

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 and other
persons, as well as for the protection of the 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 instruc-
tions 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.

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 draw•
GC -5
ings for temporary construction or construction processes, or by other means or method, is agrer.d by
the Contractor to be for the purpose of observing the extent and nature of work completed or being per-
formed, 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 com-
pleted 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 affect the work under this contract. No 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 Workmen
The Contractor agrees to employ only orderly and competent men, 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 man or men on the work are, in his opinion, incompetent, unfaithful or
disorderly, such man or men 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 -men, 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 ob-
servation, 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 checked copies, unless otherwise specified, of all shop and/or set-
ting 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 cor-
rections required by the Engineer, file with him two corrected copies and furnish such other copies as
may be needed. The Engineer's approval 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 responsi-
bility 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 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 sufficiency of said 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 rela-
tion 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 Detects 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.
2.15 Changes and Alterations
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 expenses incurred ir. prepare.
tion 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 Contrator their respective reports, opinions,
questions, answers and clarifications concerning the plans, specifications and work but shall 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 prosecu-
tion of the work and its conformity with the plans and specifications but shall never be, in whole or part,
responsible for. charged with, nor shall he assume, any authority or responsibility for the means,
methods or manner of completing the work or of the superintendence of the work or of the Contractor's
employees. It is expressly understood and agreed that any such inspector is not authorized by the Engi-
neer or Owner to independently act for either or answer on behalf of either, any inquiries of the Con-
tractor concerning the plans, specifications or work. No inspector's opinion; advice; interpretation of the
plans or specifications of this contract; apparent or express approval of the means, methods or manner
of Contractor's performance of work in progress or completed; or discovery or failure to discover or
object to defective work of materials shall release Contractor from his duty to complete all work in strict

Contractor shall furnish satisfactory evidence that all obligations of the nature hereinabove designated
have been paid, discharged or waived. If the Contractor fails to do so, then the Owner may at the option
of the Contractor either pay directly any unpaid bills, of which the Owner has written notice, or withhold
from the Contractor's unpaid compensation a sum of money deemed reasonably sufficient to liquidate
any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully

4. Prosecution and Progress
4.01 Time and Order of Completion
It is the meaning and intent of this contract. unless otherwise herein specifically provided, that the Con-
tractor shall be allowed to prosecute his work at such times and seasons, in such order of precedence,
and in such manner as shall be most conducive to economy of construction; provided, however, that the
order and the time of prosecution shall be such that the work shall be substantially completed as a whole
and in part, in accordance with this contract, the plans and specifications, and within the time of com-
pletion designated in the Proposal; provided, also, that when the Owner is having other work done,
either by contract or by his own force, the Engineer may direct the time and manner of constructing the
work done under this contract, so that conflict will be avoided and the construction of the various works
being done for the Owner shall be harmonized.
The Contractor shall submit, at such times as may reasonably be requested by the Engineer, schedules
which shall show the order in which the Contractor proposes to carry on the work, with dates at which
the Contractor will start the several parts of the work, and estimated dates of completion of the several
parts.
4.02 Extension of Time
Should the Contractor be delayed in the completion of the work by any act or neglect of the Owner or
Engineer, or of any employee of either, or by other contractors employed by the Owner, or by changes
ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoid-
able cause or causes beyond the Contractor's control, or by any cause which the Engineer shall decide
justifies the delay, then an extension of time shall be allowed for completing the work, sufficient to com-
pensate for the delay, the amount of the extension to be determined by the Engineer, provided, however,
that the Contractor shall give the Engineer prompt notice in writing of the cause of such delay.
4.03 Hindrances and Delays
No claims shall be made by the Contractor for damages resulting from hindrances or delays from any
cause (except where the work is stopped by order of and for the convenience of the Owner) during the
progress of any portion of the work embraced in this contract. In case said work shall be stopped by the
act of the Owner, then such expense as in the judgment of the Engineer is caused by such stoppage of
said work shall be paid by the Owner to the Contractor.
5. Measurement and Payment
5.01 Quantities and Measurements
No extra or customary measurements of any kind will be allowed, but the actual measured and /or com-
puted length, area, solid contents, number and weight only shall be considered, unless otherwise spe-
cifically provided.
5.02 Estimated Quantities
This agreement, including the specifications, plans and estimate, is intended to show 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 approxi-
mate 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 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 the material furnished.
GC -13
Where payment is based on the unit price method, the Contractor agrees that he will make no claim for
damages, anticipated profits or otherwise on account of any differences which may be found between the
quantities of work actually done, the material actually furnished under this contract and the estimated
quantities contemplated and contained in the proposal; provided, however, that in case the actual quan.
tity of any major item should become as much as 20% more than. or 20% less than the estimated or con-
templated quantity for such items, then either party to this Agreement, upon demand, shall be entitled
to a 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 that has a
total cost equal to or greater than five (5) per cent of the total contract cost, computed on the basis of
the proposal quantities and the contract unit prices.
Any revised consideration is to be determined by agreement between the parties, otherwise by the terms
of this Agreement, as provided under "Extra Work.'
5.03 Price of Work
In consideration of the furnishing of all the necessary labor, equipment and material, and the completion
of all work by the Contractor, and on the completion of all work and on the delivery of all material em-
braced in this Contract in full conformity with the specifications and stipulations herein contained, the
Owner agrees to pay the Contractor the prices set forth in the Proposal hereto attached, which has been,.
made a part of this contract. The Contractor hereby agrees to receive such prices in full for furnishing all
material and all labor required for the aforesaid work, also for all expense incurred by him, and for well
and truly performing the same and the whole thereof in the manner and according to this Agreement.
5.04 Partial Payments
On or before the 1st day of each month, the Contractor shall submit to the Engineer a statement showing
the total value of the work performed up to and including the 25th day of the preceding month. The state-
ment shall also include the value of all sound materials delivered on the job site and to be included in the
work 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 10th day of the current month the total
amount of the approved statement, less 10 per cent of the amount thereof, which 10 per cent shall be
retained until final payment, and further less all previous payments and all further sums that may be
retained by the Owner under the terms 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, the 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 condi-
tions 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 por-
tions 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 "substan-
tially 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 comple-
tion'' of the structure or facility shall not excuse the Contractor from performing all of the work under.
taken, whether of a minor or major nature. and thereby completing the structure or facility in accor-
dance with the Contract Documents.

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 tune, if the work be found to be completed in accordance with the Contract Documents, the Engi•
neer shall issue to the Owner and the Contractor his Certificate of Completion, and thereupon it shall be
the duty of the Owner within ten (10) days to issue a Certificate of Acceptance of the work to the Con•
tractor 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 measure-
ments and prepare final statement for the value of all work performed 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 terms 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 fulfill-
ment of any warranty which may be required.
5.08 Payments Withheld
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.
lb) 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 another contractor.
(e) Reasonable doubt that the work can be completed for the unpaid balance of the contract amount.
(fl Reasonable indication that the work will not be completed within the contract time.
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 be made for amounts
withheld because of them.
5.09 ()cloyed Payments
Should the Owner fail to make payment to the Contractor of the sum named in any partial or final state-
ment, 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 here-
under. -

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
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 in-
crease in the Contract Price, the Contractor shall make written request to the Engineer for a written
Field Order.
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 be made prior to beginning the work
covered by the proposed change:

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 transporta-
tion 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 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 avail-
able 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 incor-
porated in the Written Extra Work Order. The fifteen (15%1 per cent 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 pri-

marily 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 pro-
vided 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 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 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 ;,y 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
In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after writ.
ten notification from the Owner, or the Engineer, or if the Contractor fails to comply with the orders of
GC -17
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 machin-
ery, 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 Con-
tractor, 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 there-
for. 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 noti-
fied 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 Con-
tractor 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 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
In case the Owner shall fail to comply with the terms 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 terms 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 terms of this Agreement.
8. Subcontractors
8.01 Award of Subcontracts for Portions of the Work
Unless otherwise specified in the Contract Documents or in the Instructions to Bidders, the Contractor,
as soon as practicable after the award of the Contract, shall furnish to the Engineer in writing for accep-
tance 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 Sub-
contractor 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 m the Contract Documents or in the Instructions to Bidders or, if none is so desig-
nated, 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 sub-
mitted 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 written
agreement between the Contractor and the Subcontractor (and where appropriate between Subcontrac-
tors 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 be 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 Docu-
ments;
(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
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 com-
pleted, 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.
9. Separate Contracts
9.01 Owner's Right to Award Separate Contracts
The Owner reserves the right to award other contracts in connection with other portions of the project
under these or similar conditions of the Contract.
When separate contracts are awarded for different portions of the Project, The Contractor" in the
contract documents in each case shall be the contractor who signs each separate contract.
9.02 Mutual Responsibility of Contractors
The Contractor shall afford other contractors reasonable opportunity for the introduction and storage of
their materials and equipment and the execution of their work, and shall properly connect and coofr
dinate his work with theirs.

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 so to 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
attorney's fees and court or arbitration costs which the Owner has incurred.

materials as approved by the Engineer.
(2) Cleaning Existing Surfaces
Prior to placing the seal coat, loose dirt, and other objectionable material shall be removed
from the existing surface. The surface will be cleaned with a rotary broom. Hand brooms will
be used in areas not accessible to rotary brooms. The Engineer must approve all streets
before application of any asphalt.
(3) Application of Asphaltic Material
Immediately following the preparation of the existing surface by cleaning, the asphaltic
material shall be so applied that uniform distribution is obtained at all points. Skip streaks '
on the pavement, due to defective distributor nozzles, will be re -shot with hand operated
sprayer.
Building paper shall be spread as directed by the Engineer at designated areas on the
surface for a sufficient distance back from the end of each application so that flow through
sprays may be started and stopped on the paper, and so that all sprays will operate
properly over the entire length being treated. Building paper so used shall be immediately
removed and loaded on a truck. At the end of each day, the paper shall be disposed of at a
site approved by the Engineer.
Application temperatures will be as prescribed in Item 301, "Asphalts, Oils and Emulsions."
When a street to be sealed is continuous through several intersections, sealed area will
include all spandrels and stub -outs, unless otherwise directed by the Engineer. Spandrels
will be hand - sprayed.
The contractor shall be required to seal all spandrels at the same time the adjacent streets
are sealed, unless otherwise approved in writing by the Engineer.
During all applications, the surface of adjacent structures shall be protected in such a
manner as to prevent their being splattered or marred. Building paper shall be spread on all
manholes, valve boxes, junction boxes, etc. as directed by the Engineer to protect the sur-
face from asphaltic materials. The asphaltic material shall not be applied until the cover
aggregate is available and ready to spread with assurance of continuous operation.
No asphaltic material shall be placed which cannot be covered and rolled during daylight
hours.
312-2
(4) Spreading the Aggregate
The covering material in the quantity specified shall be spread uniformly over the
bituminous material as soon after application as possible. The aggregate shall be spread in
the same width of application as for the asphaltic material, and spread uniformly with the
aggregate spreading equipment.

Trucks spreading aggregate shall be operated backward so that bituminous material will
be covered before truck wheels pass over it. The aggregate shall not be applied in such thick-
ness to cause blanketing or stacking. Beckspotting or sprinkling cover aggregate shall be
done by hand spreading, which will be continued during the operations whenever necessary,
as directed by the Engineer.
Trucks used in hauling or spreading aggregate shall be measured by the Engineer in the
presence of the contractor and the volume of each determined. Trucks of unequal volume
will not be allowed.
If the contractor employs a mechanical aggregate spreader in his seal operation, the spreader
will be operated in such a manner that the Engineer can determine at all times during the
spreading operation the rate of application of the aggregate.
(5) Brooming and Rolling
Rolling shall be started as soon as sufficient aggregate is spread to prevent pick -up and
continued until no more aggregate can be worked into the surface. The surface shall be
blanket rolled with a flat wheel roller at least once. The contractor shall arrange his work
so that all flat wheel rolling of all cover aggregate applied that day is accomplished prior to
sundown. After completion of rolling with flat wheel roller, cover aggregate will be rolled
a minimum of four (9) complete coverages with pneumatic rollers.
In lieu of the rolling equipment specified, the contractor may, upon written permission from
the Engineer, operate other compacting equipment that will produce equivalent relative
compaction in the same period of time as the specified equipment.
Rollers shall be maintained in good repair and operating condition and shall be approved by
the Engineer.
The poney blading or drag - brooming should start as soon as possible after the rolling has
started and the surface has set sufficiently to prevent excessive marking of the seal surface.
Further pony blading or drag- brooming should be done as often as necessary to keep cover
aggregate uniformly distributed over the street surface. At no time shall there be less than
two pneumatic tire rollers on the job. The use of the poney blade or drag -broom in connection
with the rolling will be left to the opinion of the Engineer as to which gives the desired
results.
The contractor will be responsible for maintaining all streets for 48 hours after each street
has been seal coated. Maintenance will consist of brooming, rolling and adding more aggre-
gate as directed by the Engineer.
(6) Asphaltic Material Contractor's Responsibility
The contractor shall furnish vendor's certified test report for each carload, or equivalent, of
asphaltic material shipped for the project. The report shall be delivered to the Engineer
before permission is granted for use of the material.
Warning to Contractors
Attention is called to the fact that asphaltic materials are flammable. The utmost care
shall be taken to prevent open flames from coming in contact with the asphaltic material or
the gases of same. The contractor shall be responsible for any fires or accidents which may
result from heating the asphaltic material.
312.5 Traffic Control Facilities
The Contractor shall arrange the seal coat, operation in such a manner as to avoid excessive inconven-
ience to the public in the seal coat area.
The Contractor shall notify all abutting property owners along the street prior to seal coat operation.
3123
The Contractor shall have on the project site sufficient barricades, flagmen, and traffic control devices
to assure a minimum of inconvenience to traffic around the construction area. If such arrangements are
not made by the Contractor to the satisfaction of the Engineer, the seal coat operation shall not be
allowed to continue.
The Contractor shall on all streets, after the seal has been applied, post slow signs along these streets,
and maintain such signs for twenty-four (24) hours. If the Contractor so desires, the Traffic Engineer for
the City of Austin will make such signs available. If the Contractor obtains such signs from the City,
the Contractor will be held accountable to return all signs in good condition. All signs that are lost or
damaged will be replaced in accordance with the specifications of the Traffic Engineer. Replacement will
be made before payment will be made on the final estimate.
312.6 Measurement
Asphaltic material will be measured in gallons at the applied temperature at the point of application on
the street.

340.5 Stockpiling, Storage, Proportioning and Mixing
(1) Stockpiling of Aggregates
Prior to stockpiling of aggregates, the area shall be cleaned of trash, weeds and grass and be
relatively smooth. Aggregates shall be stockpiled in such a manner as to prevent mixing of
one aggregate with another. Coarse aggregates for Type "B" and Type "C" shall be
separated into at (east two stockpiles of different gradation, such as a large coarse aggregate
and a small coarse aggregate stockpile and such that the grading requirements of the speci-
fied type will be met when the piles are combined in the asphaltic mixture. No coarse
aggregate stockpile shall contain more than 15 percent by weight of material that will pass a
No. 10 sieve except as noted on the plans. Fine aggregate stockpiles may contain coarse
aggregate in the amount of up to 20 percent by weight, however, the coarse aggregate shall
meet the quality tests specified herein for "Coarse Aggregates." Suitable equipment of
acceptable size shall be furnished by the Contractor to work the stockpiles and prevent
segregation of the aggregates.
(2) Storage and Heating of Asphaltic Materials
The asphaltic material storage shall be ample to meet the requirements of the plant. Asphalt
shall not be heated to a temperature in excess of that specified in the Item, "Asphalts, Oils
and Emulsions." All equipment used in the storage and handling of asphaltic material shall

will be no contamination with foreign matter.
(3) Feeding and Drying of Aggregate
The feeding of various sizes of aggregate to the dryer shall be done through the cold aggre-
gate bin and proportioning device in such a manner that a uniform and constant flow of
materials in the required proportions will be maintained. When specified on the plans, the
cold aggregate bins shall be charged by use of a clamshell, dragline, shovel or front end
loader. The aggregate shall be dried and heated to the temperature necessary to produce a
mixture having the specified temperature. In no case shall the aggregate be introduced into
the mixing unit at a temperature more than 400 °F.
(4) Proportioning
The proportioning of the various materials entering into the asphaltic mixture shall be as
directed by the Engineer and in accordance with these specifications. The feedings of various
sizes of aggregate to the dryer -drum mixer shall be done through the cold aggregate bin and
feed system in such a manner that a uniform and constant flow of materials in the required
proportions will be maintained. Aggregate shall be proportioned by weight ns the weigh
box and batching scales herein specified when the weight -batch type of plant is used and by
volume using the hot aggregate proportioning device when the continuous mixer type of
plant is used. The asphaltic material shall be proportioned by weight or by volume based on
weight using the specified equipment.
(5) Mixing
(a) Batch Type Mixer

340.6 Construction Methods
The prime coat, tack coat or the asphaltic mixture when placed with a spreading and finishing machine,
shall not be placed when the air temperature is below 60 °F and is falling, but it may be placed when the
air temperature is above 50 °F and is rising. The air temperature shall be taken in the shade away from
artificial heat. It is further provided that the prime coat, tack coat or asphaltic mixture shall be placed
only when the humidity, general weather conditions and temperature and moisture condition of the base,
in the opinion of the Engineer, are suitable.
If the temperature of the asphaltic mixture of a load or any part of a load becomes 50 °F or more less
than the temperature selected by the Engineer under subarticle 340.5151 of this specification after being
dumped from the mixer and prior to placing while passing through the lay-down machine. all or any part
of the load may be rejected and payment will not be made for the rejected ma'erial.
(1) Prime Coat
If a prime coat is required, it shall be applied conforming to the requirements of the Item,
"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 completely cured to the satisfaction of the Engineer.
(2) Tack Coat
Before the asphaltic mixture is laid, 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
Pe, 7-1-75
travel through the mixer shall be so coordinated that a uniform mixture of the speci-
fied grading and asphalt content will be produced. The differential in temperature of
the aggregates and the asphalt as they enter the pug mixer shall not exceed 25 °F.
Checks on the asphalt used shall be made at least twice daily by comparing the
asphalt used in ten loads of completed mix as shown on the asphalt recording meter
and the design amount for these ten loads. The acceptable percent of variation
between the asphalt used and the design amount will be as shown on the plans or as
determined by the Engineer.
(c) 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.
(d) Produced Mixture
The mixture produced from each type of mixer shall not vary from the specified mix
ture by more than the tolerances herein specified.
(e) Asphaltic Mixture
The asphaltic mixture from each type of mixer shall be a temperature between 225 °F
and 350 °F when discharged from the mixer. The Engineer will determine the tempera-
ture, within the above limitations, and the mixture when discharged from the mixer
shall not vary from this selected temperature more than 25°F.
(1) Temporary Storing
Temporary storing or holding of the asphaltic mixture by the surge - storage system
may be used during the normal day's operation. Overnight storage will not be per-
mitted unless authorized in the plans or in writing by the Engineer. The mixture com•
ing out of the surge.storage bin must be of equal quality to that coming out of the
mixer. The mixture when discharged from the plant shall have a moisture content not
• greater than 3% by weight unless otherwise permitted by the Engineer. The moisture
content shall be determined in accordance with Test Method Tex - 103 -E.
340 -11
uniform application of tack coat using asphaltic materials of this specification. This tack
coat shall be applied, as directed by the Engineer, with an approved sprayer at a rate not to
exceed 0.05 gallons per square yard of surface. Where the mixture will adhere to the surface
on 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 pneumatic tire roller when directed by the Engineer.
(3) Transporting Asphaltic Concrete
The asphaltic mixture, prepared as specified above, shall be hauled to the work in tight
vehicles previously cleaned of all foreign material. The dispatching of the vehicles shall be
arranged so that all material delivered may be placed, and all rolling shall be completed
during daylight hours. In cool weather or for long hauls, canvas covers and insulating of
the truck bodies may be required. The inside of the truck body may be given a light coating
of oil, time slurry or other material satisfactory to the Engineer, if necessary, to prevent
mixture from adhering to the body.
(4) Placing
(a) Generally the asphaltic mixture shall be dumped and spread on the approved prepared
surface with the specified spreading and finishing machine, in such manner that when
properly compacted the finished pavement will be smooth, of uniform density and will
meet the requirements of the typical cross sections and the surface tests. During the
application of asphaltic material, care shall be taken to prevent splattering of adjacent
pavement, curb and gutter and structures.
When automatic screed controls for asphaltic concrete spreading and finishing
machines are required, the grade reference used by the Contractor may be of any type
approved by the Engineer. Control points if required by the plans or Engineer will be
established for the finished profile by the Engineer. These points will be set on both
sides of the course being laid, when necessary, at intervals not to exceed 50 feet. The
Contractor shall set the grade reference for the sensor of the automatic control to
follow from the control points established by the Engineer and the grade reference
shall have sufficient support so that the maximum deflection shall not exceed 1/16
inch per 25 feet.
(b) In placing a level -up course with the spreading and finishing machine, binder twine or
'cord shall be set im line -and grade established by the Engineer. When directed by
the Engineer, level -up courses shall be spread with the specified motor grader.
When the asphaltic mixture is placed in a narrow strip along the edge of an existing
pavement, or used to level up small areas of an existing pavement or placed in small
irregular areas where the use of a finishing machine is not practical, the finishing
machine may be eliminated when authorized by the Engineer, provided a satisfactory
surface can be obtained by other approved methods.
(d) Flush Structures
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.
340.12

(5) Compacting
(a) As directed by the Engineer, the pavement shall be compressed thoroughly and uni-
formly to the required density.
(b) Rolling with the three wheel and tandem rollers shall start longitudinally at the sides and
proceed toward the center of the pavement, overlapping on successive trips by at least
half the width of the rear wheel unless otherwise directed by the Engineer. Alternate
trips of the roller shall be slightly different in length. On super - elevated curves, rolling
shall begin at the low side and progress toward the high side unless otherwise directed

by the Engineer. Rolling with pneumatic -tire roller shall be done as directed by the
Engineer. Rolling shall be continued until no further compression can be obtained
and all roller marks are eliminated. If the Contractor elects, he may substitute the
three axle tandem roller for the two axle tandem roller and /or the three wheel roller;
but in no case shall less than two rollers be in use on each job. Additional rollers shall
be provided if needed. The motion of the roller shall be slow enough at all times to
avoid displacement of the mixture. If any displacement occurs, it shall be corrected
at once by the use of rakes and of fresh mixtures where required. The roller shall not
be allowed to stand on pavement which has not been fully compacted. To prevent
adhesion of the surface mixture to the roller, the wheels shall be kept thoroughly
moistened with water, but an excess of water will not be permitted. All rollers must
be in good mechanical condition Necessary precautions shall be taken to prevent the
droping of gasoline, oil, grease or other foreign matter on the pavement, either when
the rollers are in operation or when standing.
In lieu of the rolling equipment specified, the Contractor may, upon written
permission from the Engineer, operate other compacting equipment that will produce
equivalent relative compaction as the specified equipment. If the substituted com-
paction equipment fails to produce the desired compaction as would be expected of
the specified equipment, as determined by the Engineer, its use shall be discontinued.
(c) In Place Density
It is the intent of this specification that the material be placed and compacted to 95
percent of the density developed in the laboratory test and determined by Test
Method Tex - 207 -F. The Contractor shall furnish the Engineer with field specimens
for each 2,000 square yards or part thereof, of asphaltic concrete pavement placed
and shall also patch the surface where the specimen is taken with no extra payment
being made for this work. The Engineer will specify the location where the specimen
will be taken and the Contractor shall remove the specimen on the day following
placement of the asphaltic concrete pavement. The field specimens utilized for the in
place density testing may be either cores or sections of asphaltic pavement. Other
methods of determining in place density which correlate satisfactorily with those
results obtained through use of the test method Tex -207 -F may be used. In place
density tests are intended for compaction control tests. If the in place density of the
mixture produced has a value lower than that specified and in the opinion of the
Engineer is not due to a change in the quality of the material, production may pro-
ceed with subsequent changes in the mix and /or construction operations until the
in place density equals or exceeds the specified density.
(d) Hand Tamping
The edges of the pavement along curbs, headers and similar structures, and all places
not accessible to the roller, or in such positions as will not allow thorough compaction
with the rollers, shall be thoroughly compacted with lightly oiled tamps.
(e) Rolling with the trench type roller will be required on widening areas in trenches and
other limited areas where satisfactory compaction cannot be obtained with the rollers
specified or approved.
(6) Surface Tests
The surface of the pavement, after compression, shall be smooth and true to the established
line, grade and cross section, and when tested with a 10 foot 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 1/8 inch in 10 feet, and any point
in the surface not meeting this requirement shall be corrected as directed by the Engineer.
The completed surface shall meet the approval of the Engineer for riding surface finish and
appearance.
340 -13
(7) Opening to Traffic
The pavement shall be opened to traffic when directed by the Engineer. 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 and other defects shall be corrected at the Contractor's expense as
directed by the Engineer.
