1.14 TRADE NAMES AND MATERIALS:
A. Where materials or equipment are specified by a trade or brand
name, it is not the intention of the Owner to discriminate against an equal
product of another manufacturer, but rather to set a definite standard of
quality or performance, and to establish an equal basis for the evaluation
of the bids. Where the words "equivalent", or "proper", or "equal to" are
used, they shall be understood to mean that the thing referred to shall be
proper, the equivalent of, or equal to some other thing, in the opinion or
judgment of the Engineer. Unless otherwise specified, all materials shall
be the best of their respective kind and shall be in all cases fully equal
to approved samples. Notwithstanding that the words "or equal to" or other
such expressions may be used in the Specifications in connection with a
material, manufactured article or process, the designated article or process
shall be used, unless a substitute shall be approved in writing by the
Engineer, and the Engineer shall have the right to require the use of such
specifically designated material, article or process.
B. In considering any equipment offered as a substitute for equipment
named in the Specifications, proof of equality is the responsibility of the
Contractor and/or supplier, and it is not the responsibility of the Engineer
to prove the equality of proposed substitutions. Furthermore, the decision
of the Engineer is final and incontestable. It shall be the responsibility
of the Contractor to submit with each request for approval of substitute
material or equipment, sufficient data to show conclusively that it is equal

or materials immediately after receiving notice from the Engineer, the

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, exhaus-
tive, 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, se-
quences, 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,

lng or attempting to perform any of the work.
2.03 PAYMENTS FOR WORK. The ENGINEER shall review CONTRACTOR'S applications
for payment and supporting data, determine the amount owed to the CONTRACTOR and approve,
in writing, payment to CONTRACTOR in such amounts; such approval of payment to CONTRAC-
TOR constitutes a representation to the OWNER of ENGINEER'S professional judgment that the
work has progressed to the point indicated to the best of his knowledge, information and belief,
but such approva, l 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.
2.04 INITIAL DETERMINATIONS. The ENGINEER initially shall determine all claims,
disputes and other matters in question between the CONTRACTOR and the O~,~,~ER 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. Should the ENGI-
NEER fail to make such decision within a reasonable time, appeal to arbitration may be taken
as if his decision had been rendered against the party appealing.

opinion of either party hereto, is not in accordance with the meaning and intent of this contract,

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

shall be as binding as if given to the CONTRACTOR.
G-2 0., ....~--- ,~
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

ees 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. Engineer-
ing construction drawings and specifications as well as any additional information concerning the
work to be performed passing from or through the ENGINEER shall not he"interpreted as
requiring or allowing CONTRACTOR to deviate from the plans and specifications, the intent of
such drawings, specifications and any other such instructions being to define with particularity 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 precau-
tions 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 any agent, employee, or represen-
tative 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 proiect, including but without limitation 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 CONTRAC-
TOR'S attention' or not shall in no way relieve CONTRACTOR from his responsibility to complete
all work in accordance with said plans and speci.fications.
CONTRACTOR'S UNDERSTANDING. It is understood and agreed that the CON-
' 2.08 has, by careful examination, satisfied himself as to the nature and location of the work,
TRACTOR
the conformation of the ground, the character, quality and quantity of the materials to be encoun-
tered, 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 ;.n 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.
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 observation, shall be constructed and maintained by the CONTRAC-
TOR 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 setting drawings and schedules required for
the work of the various trades, and the ENGINEER shall pass upon them with reasonable prompt-
ness, making desired corrections. The CONTRACTOR shall make any corrections 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 responsibility for errors of any sort in shop drawings or schedules. It shall be the CONTRAC-
TOR'S responsibility to fully arid completely review all shop drawings to ascertain their effect on
his ahility 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 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 specifica-
lfions. 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 CONTRAC-
TOR, 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 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 w'~rk, should the CONTRACTOR
proceed with such work without requesting prior inspection or a~.~roval 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 he deemed by' the ENGINEER as unsuitable or not in conformity with the speci-
t'ications, 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 CItANGES AND ALTERATIONS. The CONTRACTOR further agrees that the OWNER
max' 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
,~r 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 Pay-
ment.'' If the amount of work is increased, and the work can fairly be classified under the speci-
fications, su~ 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 in pr. eparation
for the work as originally planned
3. GENERAL OBLIGATIONS AND RESPONSIBILITIES
3.01 KEEPING OF PLANS AND SPECIFICATIONS ACCESSIBLE. The ENGINEER shall

proper means to protect the adjacent or adjoining property or properties in any way encountered,
which might be injured or seriously affected by any process of construction to be undertaken under
this Agreement, from any damage or injury by reason of said process of construction; and he shall
be liable for any and all claims for such damage on account of his failure t° fully protect all
adjoining property. The CONTRACTOR agrees to indemnify, save and hold harmless the OWNER
and ENGINEER against any claim or claims for damages due to any iniury to any adjacent or
adjoining property, arising or growing out of the performance of the contract; but any such
indemnity shall not apply to any claim of any kind arising out of the existence or character
of the work.
3.13 PROTECTION AGAINST CLAIMS OF SUB-CONTRACTORS, LABORERS, MATER.
IALMEN AND FURNISHERS OF MACHINERY, EQUIPMENT AND SUPPLIES. The CONTRAC.

the OWNER, the CONTRACTOR shall furnish satisfactory evidence that all obligations of the
1
1
G-6
nature hereinabove designated have been paid, discharged or waived. If the CONTRACTOR fails
so to do, then the O~,~,',~ER may at the option of the CONTRACTOR either pay directlp- 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 discharged,
whereupon payments to the CONTRACTOR shall be resumed in full, in accordance with the terms
of this contract, but in no event shall the provisions of this sentence be construed to impose any
obligation upon the OWNER by either the CONTRACTOR or his Surety.
3.14 PROTECTION AGAINST ROYALTIES OR PATENTED INVENTION.-The CON-
TRACTOR shall pay all royalties and license fees, and shall provide for the use of any design,
device, material or process covered by letters patent or copyright by suitable legal agreement

from any loss on account thereof, except that the OWNER shall defend all such suits and claims
and shall be responsible for all such loss when a particular design, device, material or process or
the product of a particular manufacturer or manufacturers is specified or required by the OWNER;
provided, however, if choice 'of alternate design, device, material or process is allowed to the
CONTRACTOR, then CONTRACTOR shall indemnify and save OWNER harmless from any loss
on account thereof. If t~:e material or process specified or required by the OWNER is an infringe-
ment, the CONTRACTOR shall be responsible for such loss unless he promptly gives such
information to the OWNER.
3.15 LAWS AND ORDINANCES. The CONTRACTOR shall at ali times observe and comply
with all Federal, State and local laws, ordinances and regulations, which in any manner affect the

CONTRACTOR or his employees, except wl~ere such violations are called for by the provisions
of the Contract Documents. If the CONTRACTOR observes that the plans and specifications are
at variance therewith, he shall promptly notify the ENGLNEER in writing, and any necessa~'
changes shall be adjusted as provided in the contract for changes in the work. If the CONTRAC-
TOR performs any' work knowing it to be contrary to such laws, ordinances, rules and regulations,
and without such notice to the ENGINEER, he shall bear all costs arising therefrom. In case the
O~,'~',~ER is a body politic and corporate, the law from which it derives its powers, insofar as the
same regulates the objects for which, or the manner in which, or the conditions under which the
OWNER map' enter into contract, shall be controlling, and shall be considered as part of this
contract, to the same effect as though embodied herein.

that he will not assign by Power of Attorney, or otherwise, or sublet said contract without the
written consent of the ENGINEER, and that no part or feature of the work will be sublet to
anyone objectionable to the ENGINEER or the O~ER. The CONTRACTOR further agrees
that the subletting of any portion or feature of the work, or materials required in the performance
of this contract, shall not relieve the CONTRACTOR from his full obligations to the OV~ER, as
provided by this Agreement.
3.17 INDEMNIFICATION. The CONTRACTOR sha:,l defend, indemnify and hold harmless
the OWNER and the ENGINEER and their resoective officers, agents and employees, from and
against all damages, claims, losses, demands, suits, judgments and costs, including reasonable

The obligation of the CONTRACTOR under this Paragraph shall not extend to the liability
,'Df the ENGINEER, his agents or employees arising out of the preparation or approval of maps,
drawings, reports, surveys, Change Orders, designs or specifications, or the giving of or the
failure to give directions or instructions by the ENGINEER, his agents ar employees, provided
such giving or failure to give is the primary cause of the injury or damage.
3.18 INSURANCE. The CONTRACTOR at his own expense shall purchase, maintain and
keep in force such insurance as will protect him from claims set forth below which may arise out
of or result from the CONTRACTOR'S operations under the Contract, whether such operations

The CONTRACTOR shall also file with the O~,~ER valid Certificates of Insurance covering
all sub-contractors.
~,. 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 CONTRACTOR 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 completion
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.
G-8 ~" ...... ~
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 unavoidable 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
compensate 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 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 computed length, area, solid contents,
number and weight only shall be considered, unless otherwise specifically 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 approximate and are to be used only as a basis for
estimating the probable cost of the work and for comparing the proposals offered for the 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.
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 mate. rial actually furnished
under this contract and the estimated quantities contemplated and contained in the proposal;
provided, however, that in case the actual quantity of any major item should become as much
as 20% more than, or 20q less than the estimated or contemplated 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 of the delivery of all material embraced 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. G-9
5.04 PARTIAL PAYMENTS. On or before the 10th day of each month, the CONTRACTOR
shall prepare and submit to the ENGINEER for approval or modification a statement showing as
completely as practicable the total value of the work done by the CONTRACTOR up to and
including the last day of the preceding month: said statement shall also include the value of all
sound materials delivered on the site of the work that are to be fabricated into the work.
The OWNER shall then pay the CONTRACTOR on or before the 15th 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 fu!!y complete the work and, thereupon, the CON-
TRACTOR shall receive payment of the balance due him under the contract subject only to the
conditions stated tinder "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 CO~NTRAC-
TOR shall furnish to the E~GINEER in writing a detailed list of unfinished work. The E.~'IN-EER
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.
5.06 FINAL COMPLETION AND ACCEPTANCE. Within ten (10) days after the CON-
TRACTOR 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 or substantially completed in accordance with
tile Contract 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 within ten (10) days
to issue a Certificate of Acceptance of the work to the CONTRACTOR or to advise the CONTRAC-
TOR in writing of the reason for non-acceptance.
5.07 FINAL PAYY, IENT. Upon the issuance of tile Certificate of Completion, the ENGI-
NEER shall proceed to make final measurements and prepare final statement of the value of all
work performed and materials furnished under the terms of the Agreement and shall certify same
to the OWNER. who sl~all pay to the CONTRACTOR on or after tile 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 Agreement, provided he has fully performed his contractual obligations
under the terms of this contract: and said payment shall become due in any event upon said
performance bv the CONTRACTOR. Neither tile 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 WITIIHELD. 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.
(b) Claims filed or reasonable evidence indicating probable filing of claims.
(c) Failure of the CONTRACTOR to make payments properly to sub-
contractors 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.
(f) 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 DELAYED PAYMENTS. Should the OWNER fail to make payment to the CONTRAC-
TOR 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 o[~'si~ cent per annum, unless otherwise specified, from date due as
provided under "Partial Payments" and "Final Payments," until full./ paid, which shall fully
liquidate any injury to the CONTRACTOR growing out of such delay in payment, but the right
is expressly reserved to the CONTRACTOR in the event payments be not promptly made,
as provided under "Partial Payments," to at any time thereafter treat the contract as abandoned
cover corn ensation, as provided under "Abandonment of Contract," unless
by the OWNER and re p . . . ,, · ,,
&~t such payments are withheld in accordance w~th the prov,mons of Payments W~thheld.
. York rime rate plus two percent (but in no event more than

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 C(~NTRACTOR 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 herein-
after 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 increase in the Contract Price,
the CONTRACTOR shall make written request to the ENGINEER for a written Field Order.
In such case, the CONTRACTOR by colby 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 an'd that the 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.
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 one or more of the following methods:
G-11
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 pro-
visions 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, teams, trucks, rentals on machinery and 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 law or ordinance,
or directed by the OWNER, or by them agreed to. The ENGINEER may direct the form in which
accounts of the "actual field cost" shall be kept and the records of these accounts shall be made
available to the ENGINEER. The ENGINEER or OWNER may also specify in writing, before the
work commences, .the meth6d of doing the work and the type and kind of machinery and equip-
ment 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 th~ 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%) per cent of the "actual field cost" to be paid the CONTRAC-
TOR 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 ~vriting by the
ENGINEER. In case any orders or instructions, either oral or written, appear to the CONTRAC-
TOR 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 oxceptions 0y 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 where 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 question submitted to arbitration
under this contract shall be a condition p~ecedent to any right of legal action. The decision of
the arbiter or arbiters may be filed in court to carry it into effect.
The arbiters, if they deem the case demands it, are authorized to aWard the party whose
contention is sustained, such sums as they deem proper for the time, expense and trouble incident
to the appeal, and if the appeal was taken without reasonable cause, they may award damages for
any delay occasioned thereby. The arbiters shall fix their own compensation, unless otherwise-
provided by agreement, and shall assess the cost and charges of the arbitration upon either or both
parties. The award of the arbiters must be made in writing.
7. ABANDONMENT OFCONTRACT
7.01 ABANDONMENT BY CONTRACTOR. In case the CONTRACTOR should abandon
and fail or refuse to resume work Within ten (10) days after written notification from the OWNER,
or the ENGINEER, or if the CONTRACTOR fails to comply with the orders of the ENGINEER,
when such orders are consistent ,with the Contract Documents, then, and in that case, where
performance and payment bonds exist, the Sureties on these bonds shall be notified in writing and
directed to complete the work, and a copy of said notice shall be delivered to the CONTRACTOR.
After receiving said notice of abandonment the CONTRACTOR shall not remove from the
work any machinery, equipment, tools, materials or supplies then on the job, but the same,
together with any materials and equipment under contract for the work, may be held for use on the
work by the OWNER or the Surety on the performance bond, or another contractor in completion
of the work; and the CONTRACTOR shall not receive any rental or credit therefor (except when
used in connection with Extra Work, where credit shall be allowed as provided for under Section 6,
Extra Work and Claims), it being understood that the use of such equipment and materials will
ultimately reduce the cost to complete the work and be reflected in the final settlement.
Where there is no performance bond provided or in ease the Surety should fail to commence
compliance with the notice for completion hereinbefore provided.f.or, 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:
7.01.1 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 CONTRAC-
TOR 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
7.01.2 The OWNER under sealed bids, after five (5) days notice published one or more
times in a newspaper having general circulation in the county of the location of the work, may
let the contract for the completion of the work under substantially the same terms and conditions
which are provided in this contract. [n case 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 new contract prove to be less than what would have been
the cost to complete under this contract, the CONTRACTOR and/or his Surety shall be credited
therewith.
G-13 e ', '~ ~'". '~'
- When the work shall have been sUbstantially completed the CONTRACTOR and his Surety
shall be so notified and' Certificates of Completion and Acceptance, as provided in Paragraph 5.06
hereinabove, shall be issued. A complete itemized statement of the contract accounts, certified to
by the ENGINEER as being correct, shall then be prepared and delivered to the CONTRACTOR
and his Surety, whereupon the CONTRACTOR and/or'his Surety, or the OWNER as the case may
be, shall pay the balance due as reflected by said statement, within fifteen (15) days after the date
of such Certificate of Completion. .
In the event the statement of accounts shows that the cost to complete the work is less
than that which would have been the cost to the OWNER had the work been completed by the
CONTRACTOR under the terms of this contract; or when the CONTRACTOR and/or his Surety
shall pay the balance shown to be due by them to the OWNER, then all machinery, equipment,
tools, materials or supplies left on the site of the work shall be turned over to the CONTRACTOR
and/or his Surety. Should the cost to complete the work exceed the contract price, and the
CONTRACTOR and/or his Surety fail to pay the amount due the OWNER within the time
designated hereinab°ye, 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 pri~;ate 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 open 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 or refuse to comply with said terms within ten (10) days
after written notification b.v 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 ~,he 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 b.v the OWNER under the terms of this Aereement 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.

shall be effected in such a manner as not to disturb or damage the work
performed.
3.5 EMBEDMENT:
A. Bedding Layer (Below the Pipe):
The bedding layer shall be brought up to the proper grade required for
the bottom of the pipe and shall have recesses scooped out to receive the
pipe bells. The pipe shall then be placed on the graded bedding. Each pipe
section shall have uniform bearing on the bedding for the full length of the
pipe except immediately at the bell or joint. When required, adjustment of
the pipe grade line shall be made by scraping away or filling with bedding
material. Wed~inz or blockin~ up ~i~e will not be ~ermitted. When the pipe
is set firmly on grade, the bedding material shall be extended as defined
for the particular embedment selected. The final portion of the bedding
layer shall be placed and compacted to a depth as indicated for the type of
embedment.
B. Embedment Backfill Layer (Around and Above the Pipe):
The embedment backfill layer shall consist of materials from trench
cuttings, if suitable, or as outlined on the detail sheets. Ail frozen
earth, debris or organic materials will be rejected.
The embedment backfill layer shall be compacted by the method selected
by the Contractor approved by the Engineer. Hydrohammers or drop hammers
are not permitted on this lift. When the Contractor elects to use jetting,
proper care must be exercised during jetting not to disturb or displace the
material from around the pipe.
The pipe shall be bedded in the trench as described herein for the
class of bedding as required by the Plans and Specificat'ions. The various
embedments shall be prepared in accordance to Detail Sheets, and as required
by the City of Irving.

the pipe shall he backfilled with enough granular material or select
material on both sides to hold the pipe firmly in position.
Ail pipe shall be so laid that the contact in the joint between two
lengths of pipe shall be uniform throughout the circumference of the joint.
Where curves in the profile are indicated on the Drawings, standard pipe
will be used with the outside edge of the joint pulled away from the seat to
make a smooth curve. Short pipe lengths shall be used as required to assure
that pipe joint deflections do not exceed the maximum allowed.
Ail joints in pipe conduits shall be thoroughly cleaned at the time
joint is made, removing all debris, and shall be made in a careful,
thoroughly and workmanlike manner.
3.7 JOINTING: If the Contractor elects to use Portland cement mortar
joints, all pipe shall be jointed tight and sealed with stiff mortar, so
placed as to form a durable water-tight joint. The ends of the pipe shall
be cleaned thoroughly and wetted before making the joint.
If cold applied plastic asphalt sewer joint compound is used, both ends
of the pipe shall be clean and dry and shall be coated with a primer
recommended by the manufacturer. Under no circumstances shall this type of
joint be attempted on wet pipe. After the pipe has been set to proper line
and grade in the trench, a one-half inch thick layer of %he compound shall
be placed on the groove end of the pipe. Next the tongue end of the next
pipe shall be shoved home with sufficient pressure to make a tight joint.
After the joint is made, any excess mastic projecting into the pipe shall be
removed.
Where rubber gasket pipe joints are used the joint assembly shall be
made according to the recommendations of the gasket manufacturer. Water
tight joints will be required when using rubber gaskets.
If cold-applied performed plastic gaskets are used, a primer
recommended by the manufacturer shall be brush-applied to the tongue and
groove joint surfaces and the end surfaces and allowed to dry and harden.
No primer shall be applied over mud, sand or dirt, or sharp cement
protrusions. The surface to be primed must be clean and dry when primer is
applied.
Before laying the pipe in the trench, the plastic gasket shall be
attached around the tapered tongue or tapered groove near the shoulder or
hub of each pipe joint. The paper wrapper shall be removed from one side
SECTION 02502 - STORM DRAINAGE PAGE 6
only of the two-piece wrapper on the gasket and pressed firmly to the clean,
dry pipe joint surface. The outside wrapper shall not be removed until
immediately before pushing the pipe into its final position.
When the tongue is correctly aligned with the flare of the groove, the
outside wrapper on the gasket-shall be removed and the pipe shall be pulled
or pushed home with sufficient force and power to cause the evidence of
squeeze-out of the gasket material on the inside and outside around the
complete pipe joint circumference. Any joint material pushed out into the
interior of the pipe would tend to obstruct the flow shall be removed.
Special precautions shall be taken in placing and compacting backfill
to avoid damage to the joints.
3.8 BACKFILLING: As soon as practicable, all portions of excavation not
occupied by permanent structures shall be backfilled. Backfill material
shall be free from large or frozen lumps, wood, or other extraneous

3.10 CONNECTIONS: Where pipe sewers are connected to new manholes, inlets,
or headwalls, the end of the connecting pipe shall be framed into the
structure as shown on the Plans and the concrete or brick masonry shall be
placed or laid around the pipe for the full thickness of the structure wall.
Where pipe sewers are connected to existing inlets or manholes, the
connection shall be made by cutting an opening into the wall of the
structure, inserting the end of the pipe until it is flush with the inside
of the structure and completely filling the space between the pipe and
structure with concrete and mortar. The bottom of the existing structure
shall be mortared or concreted to eliminate any drainage pockets created by
the new connection, and in general accord with details for the new
structures as shown on the Plans. Where such connections involve the
setting back of inlets and connecting the sewer line through the old inlet
to the new, the old inlet, or portions thereof, shall be removed as is
required to provide a full circle pipe connection through the limits of the
old structure. Where abrupt angles are involved, vitrified clay specials
set in concrete or mortar to a depth of 6 inches over the top of the pipe
shall be employed and such connections shall be classified as pipe sewers.
Where the sewer is connected into old structures which are to remain in
service, any damage to the structure resulting from the work of making the

mixed and in accordance with requirements of the latest ACI Building Code. All
concrete shall be machine mixed in a batch mixer of an approved type having an
approved and positive water control device and so designed that all materials for
each batch can be accurately measured. The mixing shall continue until there is a
uniform distribution of materials, but not less than 1~ minutes after all materials
have been introduced into the mixer drum. The drum of the mixer shall rotate at a
peripherial speed as recommended by the mixer manufacturer.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE 9
B. Ready-mixed concrete shall be mixed and delivered to the project in
accordance with A.S.T.M. Specification C9~.
1. Mixing water shall be added at the plant.
2. The concrete shall, in all cases~ be completely discharged at the
job within 60 minutes after the introduction of the cement to the aggregate. In hot
weather, this time limit shah not exceed ~ minutes.
3. The mixing operation shall begin within 30 minutes after the
cement has been intermingled with the aggregates.
q. The ready-mix concrete producer shall furnish duplicate delivery
tickets with each load of concrete delivered to the project. The delivery tickets
shall indicate the delivery date and time dispatched; name and location of project;
name of Contractor; name of ready-mix concrete producer; truck number; number
of cubic yards of concrete in load, class of concrete, the cement content in bags
per cubic yard of concrete, admixtures in concrete and the number of gallons of
water in the mixture and air content.
3.8 TESTING OF MATERIALS:
A. All materials and equipment used in the construction of this structure
shall be adequately inspected and tested in accordance with accepted standards.
lB. Reinforcing Steel: Manufacturer's certified test sheets shall be fur-
nished the Engineer for each size bar used.
C. Concrete Tests; All concrete testing shall be made by an independent
laboratory which is to be selected by the Engineer and paid by the Owner.
1. Advance strength tests of the concrete to be used for this project
.- will be made by the laboratory in accordance with ASTM C-39. 5ix standard
cylinders will be made each of the proportioned materials proposed to be used.
Three cylinders will be tested at 7 days and three at 28 days. The slump shall not
be less than the greater slump expected to be used in the structure. These tests
will be repeated, if the results are unsatisfactory, or if necessary because of
changes in materials. Advance test will be made for each class of concrete. From
the result of the tests, a smooth curve will be drawn through the average positions
of points plotted.
2. Using the 28-day strength of the test cylinders as ordinates and
the corresponding water-cement ratio as the abscissas, the maximum ratio of
water to cement shall be established for each strength from the curve so drawn.
Points on the curve shall be selected to correspond to strengths 2~ percent greater
than the design strengths. The proportions of all concrete ingredients~ including
water, shall be selected for each strength so that the ratio of water to cement
shall not exceed that established by the curve and so that the quality and
consistency of the concrete shall be suitable for proper placing and required
finishes. The concrete proportions used by the Contractor shall be such that the
daily field cylinder tests will show that all concrete used meets the strength
requirements of the contract.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE 10
3.9 INSPECTION:
A. The Owner will pay for services of an independent testing laboratory
selected by the Engineer to perf.orm such laboratory services as are required for
this project. The engagement of the laboratory by the Owner will in no way relieve
the Contractor of his responsibility to furnish materials and construction in
conformance with these plans and specifications. The Contractor shall provide
such onsite office and laboratory facilities required by the laboratory field
representative.
The laboratory services will include but not necessarily be limited to:
1. Plant inspection, testing and sieve analyses.
The laboratory will maintain periodic plant inspection of all materials,
operation of measuring devices~ and mixing of concrete. They will maintain
personnel at job site, during placement of all concrete, for proper concrete control
and making test cylinders.
2. Test cylinders will be made by the laboratory representative at
the job site for the first two pours, regardless of size of pours~ and thereafter, for
each pour in excess of 25 cubic yards of concrete, and for each 100 cubic yards or
major fraction thereof. Five (5) cylinders will be made for each pour, two for 7-
day testing and three for 2g-day testing. The cylinders will be made on the job site
and will be cured and tested in accordance with ASTM Requirements.
3. Where 25 or more cubic yards of concrete are placed, also~ as
necessary to maintain desired consistency of the concrete~ a slump test shall be
made per ASTM C-If3. Not less than one such test shall be made for each 25 cubic
yards of concrete placed at one operation. Tests to be made by the laboratory
representative at job site.
C. During the progress of the work and for each different mix of concrete~
a set of five standard 6" concrete cylinders will be made and tested as hereinbefore
described. The cylinders of each set will be moulded from the same sample of
concrete and tested. Testing will be done per ASTM C-39. Curing shall be in
conformance with ASTM C-31. The results of these tests will be furnished to the
Contractor promptly.
1. If the strength test cylinders at 7 days or 28 days are deficient,
the Engineer may order reshoring and additional moist curing of the areas involved.
2. Below strength concrete: Should the strength of concrete, as
indicated by the above tests, fall below the ASTM minimum~ then additional tests
may be required. These tests~ if required~ will be made at the Owner's expense and
will be in accordance with ASTM Designation C-#2~ "Method of Securing~ Pre-
paring~ and Testing Specimens from Hardened Concrete for Compressive and
Flexural Strengths~" and in compliance with the Building Code requirements for
Reinforced Concrete (ACI 318-7). If the structure, or any part of the structure~
cannot pass the load test, the cost of the additional tests shall be deducted from
the Contract price, and the structure shall be removed and replaced at the
Contractor's expense.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE 11
3.10 HANDLING AND DEPOSITING CONCRETE:
A. Handling: Concrete shall be handled with dispatch after mixing and
with due care to prevent deterioration through delays, loss of water, separation of
ingredients or contamination by foreign matter. Platforms, conveyors, buckets,
barrows, chutes~ etc., used in handling concrete shall be watertight and shall be
thoroughly cleaned of old or foreign materials before materials are deposited in
them.
B. Chutes shall be metal or metal lined. In no case shall chutes be used to
convey concrete over a distance greater than 30 feet. Slope of chutes shall be not
greater than one vertical to two horizontal. A two foot long "elephant trunk" or a
suitable baffle plate shall be provided at the end of chute to prevent segregation.
C. Depositing Concrete: Before placing concrete~ debris, water~ and ice
shall be removed from the places to be occupied by the concrete. ~t/ood forms shall
be thoroughly wetted (except in freezing weather) or oiled~ and the reinforcement
cleaned of ice or other coatings. Form work and the placement of reinforcement,
pipes, sleeves~ conduit~ anchors~ and other inserts shall be installed~ inspected and
approved by the Engineer or his representative before any concrete is deposited.
1. The placing or depositing of all concrete shall be done in
accordance with the requirements of the American Concrete Institute Building
Code 318-77, and as modified herein. Concrete shall be rapidly handled from mixer
to forms and deposited as nearly as possible in its final position to avoid
segregation due to re-handling or flowing. Concrete shall be spaded and worked by
hand and vibrated to assure close contact with all surfaces of forms and reinforce-
ment and leveled off at proper grade to receive finish. No concrete that has
partially hardened or been contaminated by foreign material shall be deposited in
the work, nor shall retempered concrete be used. All concrete shall be placed upon
clean~ well thawed~ damp surfaces~ free from water and never upon soft mud or dry
porous earth. Concrete in walls and columns shall be placed and allowed to settle
two hours before placing concrete superimposed thereon. Concrete shall be placed
monolithically between construction joints except as otherwise noted or indicated.
2. Special care must be exercised in placing concrete to prevent
splashing of forms or reinforcement. The accumulation of hardened or partially
hardened concrete on the forms and reinforcement above the level of the concrete
already placed shall be removed before the work begins.
3. Concrete for all footings shall be placed independently of walls~
pedestals, and all other superimposed work unless monolithic construction is
indicated on the Drawings.
4. Concrete shall be placed in the forms through canvas "elephant
trunks" or galvanized iron chutes equipped with suitable hopper heads, to uniform
level, and at various intermediate locations, and in a manner to prevent segre-
gation. The free fall of concrete dumped or chuted into place shall not exceed 3
feet. The spreading of concrete by means of hoes or shovels in mass concrete or
footings shall be permitted for a distance not greater than four (4) feet from
location at which concrete is deposited. Columns or walls exceeding 12 feet in
height shall be placed with metal tremies.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE 12
5. Placing of concrete shall be continuous between construction
joints. The rate of placing for walls and deep beams or girders shall not exceed 2
feet in height per hour.
6. All concrete shall be placed in such a manner as to secure a
uniform thoroughly compacted homogeneous mass~ and shall be hand or machine
tamped and puddled. Both hand or machine tamping and puddling shall be
supplemented by hand forking or spading in all corners and angles of forms along all
form surfaces to prevent pitting and honeycombing at the surfaces of the concrete.
This work shall be executed in a manner and time to assure intermixing of concrete
of successive pours. Concrete for all walls, deep beams, etc., shall be placed in
layers of uniform levels, not exceeding 2 feet in depth, and the method and
sequence of such pours shall be of such order as to prevent lamination of the
various layers.
7. Before depositing fresh concrete in restricted areas of columns,
pilasters, walls, or in locations where closely spaced reinforcing occurs near the
bottom surface of the concrete to be placed, the Contractor shall deposit a 2 inch
layer of mortar composed of one part cement and two parts of fine aggregate.
8. When placing of concrete is suspended, all necessary keys for
iointing to future work shall be provided before concrete has begun to set.
Bulkhead shall be provided at sections of minimum stress.
9. Concrete to be deposited on earth~ sidewalks, etc. shall be placed
upon undisturbed or precompacted soil, free from water, frost or ice. Dry or
pervious soils shall first be wet.
10. No concrete shall be deposited on concrete which has hardened
sufficiently to cause formations of seams and planes of weakness within a section.
When placing concrete in thin sections or walls of considerable height, the
Contractor shall arrange to deposit the concrete through openings in the forms or
otherwise to avoid accumulation of hardened concrete on forms and reinforcement.
11. Connections: Before depositing new concrete on or against
concrete which has set, the forms shall be carefully inspected and re-tightened if
necessary. The surface of the set concrete shall be thoroughly cleaned of foreign
matter and laitance, and saturated with water.
12. Vibration: Concrete shall be placed with aid of mechanical
vibrating equipment. Vibration shall be applied directly to the concrete. The
intensity of vibration shall be sufficient to cause flow or settlement of the
concrete into place. Vibration shall be applied at the point of deposit and in the
areas of freshly placed concrete. It shall be of sufficient duration to accomplish
thorough compaction and complete embedment of reinforcement and fixtures~ but
shall not be long enough to cause segregation of the mix. To secure even and dense
surfaces, free from aggregate pockets or honeycomb~ vibration shall be supple-
mented by hand spading in the corners and angles of forms along form surfaces
while the concrete is plastic under the vibratory action. Caution must be exercised
when using the vibrators and hand spades to prevent any iniury to the inside face of
forms or any movement of the reinforcement.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE 13
3.11 WEATHER CONDITIONS:
A. Concrete when deposited shall have a temperature not below 50°F. and
not above 95°F. In freezing weather, suitable means shall be provided for
maintaining the concrete at a ~emperature not lower than 70°F. for 3 days, or
50VF. Ior ~ days after placing. Co~ling of the concrete to outside t~mperature
shall not be at a rate faster than Iv each hour for the first day and 2v each hour
thereafter until the outside temperature is reached. The methods of heating the
material and protecting the concrete shall be approved by the Engineer. The
maximum temperature of c~n~crete produced with heated aggregates, heated water,
or both, shall not exceed 90 F. at any time during its production or transportation.
B. Salt, chemicals or other foreign materials shall not be mixed with the
concrete for the purpose of preventing freezing.
C. Admixtures intended to accelerate the hardening of the concrete or to
produce higher than normal strength at early periods will not be permitted without
prior approval from the Engineer.
D. Mixing concrete shall be suspended at all tim~s during inclement
weather, at such times when the outside temperature is ~0 F. or lower, except
upon written consent of the Engineer. During seasons of possible low temperature,
the temperature of the concrete as discharged from the mixer shall be 70-F. or
more when the outside temperature is 5~°F. and falling. Heating of concrete to
these temperatures may be accomplished by preheating of the water and the
aggregate, by use of flame imputted into the mixer or by any combination thereof,
except th.~ temperature to which the concrete and the water are heated shall not
exceed 85 F. and 120°F., respectively. The methods and recommended practice
described in A.C.I. Standard 306 shall be followed for winter concreting.
E. Hot weather concrete shall be in accordance with the recommended
Practice for Hot Weather Concreting (ACI 605).
1. The following pre_cautions, recommendations, and procedures shall
· U
be followed during hot weather, 95 F. and above:
a. Cool the mixing water, aggregates, or both.
b. Cool the mixer drum by spraying water.
c. Use a suitable water reducing retarder.
.__ d. Keep mixing to a minimum which will insure adequate
quality.
e. Trucks shall be dispatched so as to avoid delay, and work
- shall be organized to use the concrete promptly to prevent unnecessary additional
mixing at the iob site.
- f. Forms and reinforcing steel shall be sprinkled with cool
water iust prior to placement of concrete. Other means shall be taken to reduce
temperatures of the concrete in place.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE It~
g. Speed of placement and finishing is highly essential. Water
spraying may be necessary, if plastic shrinkage cracks appear.
h. Immediately after finishing, the areas shall be protected and
wet cured continuously. See PROTECTION AND CURING.
2. A maximum of 95°F. shall be the upper limits of temperature of
the concrete at time of placing.
3.12 PROTECTION AND CURING:
A. Protect concrete against frost and rapid drying and keep moist for at
lea~st six days after placing. During this ,~e~riod concrete shall be maintained above
70VF. for at least three days or above 50 F. for at least five days. Concrete from
which forms are removed within six days after concreting, and cement finishes,
shall be sprayed during the curing period as frequently as drying conditions may
require. Cover cement finishes with mats, waterproof paper or an approved
membrane within 12 hours after finishing and maintain in good condition until the
installation of permanent floor covering, or until directed. Covering shall be of a
type that will not stain or discolor finished concrete surfaces.
1. Each day the forms are kept in place and kept wet enough to
prevent the opening of joints in the forms and the drying out of concrete will be
counted as one day of curing.
2. Concrete placed during the cold weather shall be protected
against wind and freezing, and provisions shall be made to maintain the concrete at
a temperature of not less than 50°F. nor more than 100°F until the concrete has
attained 80 percent of the strength for which it has been designed. The method of
protection of heating shall be approved by the Engineer.
3. All newly laid concrete floor surfaces shall be cured and sealed as
soon as concrete has set to where it can be walked on, with one coat of "Clear
Bond", as manufactured by Guardian Chemical Co., Atlanta, Georgia, or equal.
3.13 CONSTRUCTION JOINTS'.
A. Construction joints shall be formed as indicated on the Drawings, or as
approved or directed by the Engineer. Dowels and keys shall be used where
indicated or required. All reinforcing shall continue through construction joints
and additional reinforcing placed as shown on the Drawings. Longitudinal keys at
least 11~ inches deep shall be provided in all construction joints in walls and slabs.
B. The rate and method of placing concrete and the arrangement of
construction joint bulkheads shall be such that the concrete between construction
joints shall be placed in a continuous operation.
C. Joints in reinforced slabs, beams and girders shall be perpendicular to
the axis of surface of the member jointed and within the center third of the spans.
If an intersecting member occurs at the point, the joints shall be located at a point
three times the depth of the member to the side.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE 15
D. Construction joints in walls, columns, or piers shall be at the bottom of
connecting beam or girder. Whenever it is necessary to stop a day's work or for
any reason, such stops shall be located at center of slabs and of beams or as
directed by the Engineer. Construction and other joints in concrete walls below
grade shall have a continuous water stop as hereinbefore specified placed full
lengths in joint. Seal laps and joints of water stops tight.
E. A temporary wood bulkhead shall be erected so that the jointing will
follow a vertical plane at right angles with the direction of the main rein-
forcement. To this bulkhead fasten a wood strip 2" thick and of width equal to
the depth of the concrete slab to form a tongue and grooved joint.
F. Bond shall be obtained by roughening the surface of the concrete in an
approved manner which will not leave laitance, loosened particles of aggregate or
damaged concrete at the surface. Before concreting is resumed, the surfaces of
previously placed concrete shall be roughened, cleaned, wetted and slushed with
grout immediately before additional concrete is placed. Grout shall be I part
Portland cement and 2 parts sand.
3.1# EXPANSION JOINTS:
A. Expansion joints shall be constructed where shown on Drawings. In no
case shall reinforcement or other fixed metal items be embedded or bonded into
concrete; be run continuous through an expansion joint, except as otherwise
indicated.
B. Premolded expansion joint filler strips shall be of the type specified
hereinbefore.
C. Joint compound shall have the approval of the Engineer and shall be
installed to the proper depth below the finished floor. Joint grooves shall be filled
approximately flush so as to be slightly concave after drying.
3.15 REMOVAL OF FORMS:
A. Forms shall be removed in accordance with requirements of the ACI
Building Code Requirements for Reinforced Concrete No. 318-56, Chapter 5,
without damage to concrete and in a manner to insure complete safety of the
structure. Leave shoring in place until concrete member will safely support its
own weight plus any live loads that may be placed upon it.
B. No formwork or shoring shall be removed without the approval of the
Engineer. The removal of forms shall be carried out in such a manner as to insure
the complete safety of the work and the prevention of defects. Unless limited by
consideration of dead loading, forms or shores supporting the underside of concrete
for slabs, beams and girders shall not be removed until the concrete so supported
has acquired 70 percent of its design strength.
C. Upon removal of forms, the Engineer shall be notified by the Con-
tractor in order that an inspection of the newly stripped surfaces may be made
prior to patching, if necessary.
SECTION 03301 - CAST-IN-PLACE CONCRETE PAGE 16
3.16 PATCHING FORMED SURFACES OF CONCRETE:
A. Alter the forms have been removed, all concrete surfaces shall be
inspected and any pour joints, voids, stone pockets, or other defective areas
permitted by the Engineer to be'patched; and all tie holes, shall be patched before
the concrete is thoroughly dry. Defective areas shall be chipped away to a depth
of not less than l" with the edges perpendicular to the surface. The area to be
patched and a space of at least 6" wide entirely surrounding it shall be wetted to
prevent absorption of water from the patching mortar. Do not fill or patch
construction joints or surfaces to receive metallic waterproofing, unless speci-
fically authorized by the Engineer. Do not patch any concrete in freezing weather.
B. A grout of equal parts of Portland cement and sand with sufficient
water to produce a brushing consistency shall then be well brushed into the surface,
followed immediately by the patching mortar. Normal Portland cement shall be
mixed with white Portland cement to match color of the surrounding concrete.
The patch shall be made of the same material and of the same proportions as used
for concrete, except that the coarse aggregate shall be omitted. The amount of
mixing water shall be as little as consistent with the requirements of handling and
placing. The mortar shall be retempered without the addition of water by allowing
it to stand for a period of one hour during which time it shall be mixed with a
trowel to prevent setting.
C. The mortar shall be thoroughly compacted into place and screeded off
so as to leave the patch slightly higher than the surrounding surface. It shall then
be left undisturbed for a period of one to two hours to permit initial shrinkage
before being finally finished. The patch shall be finished in such a manner as to
match the adjoining surfaces. Tie holes left by withdrawal of rods other than these
covered by paragraph 3.2A of this Section, or the holes left by removal of ends of
ties shall be filled solidly with mortar alter being thoroughly wetted. For holes
passing entirely through the wall, a plumber type grease gun or other device shall
be used to force the mortar through the wall.
D. At the option of the Contractor, the bonding of the patching mortar to
the acceptable concrete alter necessary cutting and removal of porous or other-
wise unacceptable concrete is completed may be done by the use of an approved
bonding agent applied in accordance with the printed instructions of the manu-
lacturer. Filling and finishing of the patch shall be completed as hereinbefore
specilied.
PARY IV- PAYMENT
