2.02 PROFESSIONAL INSPECTION BY ENGINEER. The ENGINEER shall make periodic visits to the site to familiarize himself generally with the progress of the executed work and to determine
if such work generally meets the essential performance and design features and the technical and functional engineering requirements of the Contract Documents; provided and except, however,
that the ENGINEER shall not be responsible for making any detailed, exhaustive, comprehensive or continuous on·site inspection of the quality or quantity of the work or be in any way
responsible, directly or indirectly, for the construction means, methods, techniques, sequences, quality, procedures, programs, safety precautions or lack of same incident thereto or
in connection therewith, Notwithstanding any other provision of this agreement or any other Contract Document, the ENGINEER shall not be in any way responsible or liable for any acts,
errors, omissions or negligence of the CONTRACTOR, any subcontractor or any of the CONTRACTOR'S or subcontractor's agents, servants or employees or any other person, firm or corporation
performing or attempting to perform any of the work. 2.03 PAYMENTS FOR WORK. The ENGINEER shall review CONTRACTOR'S applications for payment and supporting data, determine the amount
owed to the CONTRACTOR and 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 approvl!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 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. Should the ENGINEER
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. 2.05 OBJECTIONS. In the event
the ENGINEER renders any decision which, in the opinion of either party hereto, is not in accordance with the meaning and intent of this contract, either party may file with the ENGINEER
within thirty days his written objection to the decision, and by such action may reserve the right to submit the question so raised to arbitration as hereinafter provided. 2.06 LINES
AND GRADES. Unless otherwise specified, all lines and grades shall be furnished by the ENGINEER or his representative. Whenever necessary, construction work shall be suspended to permit
performance of this work, but such suspension will be as brief as practicable and the CONTRACTOR shall be allowed no extra compensation therefor. The CONTRACTOR shall give the ENGINEER
ample notice of the time and place where lines and grades will be needed. All stakes, marks, etc., shall be carefully preserved by the CONTRACTOR, and in case of careless destruction
or removal by him or his employees, such stakes, marks, etc., shall be replaced at the CONTRACTOR'S expense. 2.07 CONTRACTOR'S DUTY AND SUPERINTENDENCE. The CONTRACTOR shall give adequate
attention to the faithful prosecution and completion of this contract and shall keep on the work, during its progress, a competent superintendent and any necessary assistants. The superintendent

2.11 SANITATION. Necessary sanitary conveniences for the use of laborers on the work, properly secluded from public observation, shall be constructed and maintained by the CONTRACTOR
in such manner and at such points as shall be approved by the ENGINEER, and their use shall be strictly enforced. 2.12 SHOP DRAWINGS. The CONTRACTOR shall submit to the ENGINEER, with
such promptness as to cause no delay in his own work or in that of any other Contractor, four checked copies, unless otherwise specified, of all shop and/or setting drawings and schedules
required for the work of the various trades, and the ENGINEER shall pass upon them with reasonable promptness, making desired corrections. The CONTRACTOR shall make any corrections required
by the ENGINEER, file with him two 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 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 relation to the safety of either person or property during CONTRACTOR'S performance
hereunder. 2.13 PRELIMINARY APPROVAL. The ENGINEER shall not have the power to waive the obligations of this contract for the furnishing by the CONTRACTOR of good material, and of his
performing good work as herein described, and in full accordance with the plans and specifications. No failure or omission of the ENGINEER to discover, obiect 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 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 >'''wk, should the CONTRACTOR proceed with such work without requesting prior inspection or al-,Jroval he shall bear all
expense of taking up, removing, and replacing this work if so directed by the ENGINEER. 2.14 DEFECTS AND THEIR REMEDIES. It is further agreed that if the work or any part thereof, or
any material brought on the site of the work for use in the work or selected for the same, shall be deemed by the ENGINEER as unsuitable or not in conformity with the specifications,

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,

of this contract and the accompanying Performance and Payment Bonds. G-4 
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 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 1055, damage or injury incident thereto, either
to person or property, including, without limitation, the adequacy of all temporary supports, shoring, bracing, scaffolding, machinery or equipment, safety precautions or devices, and
similar items or devices used by him during construction. Any review of work in process, or any visit or observation during 'i\onstruction, 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 project, 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 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;
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. G·3 
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 in preparation for the work as originally planned. 3. GENERAL OBLIGATIONS AND RESPONSIBILITIES

nature hereinabove designated have been paid, discharged or waived. If the CONTRACTOR fails SO to do, 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 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 with the patentee or owner. The CONTRACTOR shall defend all suits or claims for infringement of any patent or copyright rights and shall
indemnify and save the OWNER and ENGINEER harmless 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 a1lowel:l to the CONTRACTOR, then CONTRACTOR shall indemnify and save OWNER harmless from any loss on account thereof. If ti,e material
or process specified Or required by the OWNER is an infringement, 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 all times observe and comply with all Federal, State and local laws, ordinances and regulations, which in any manner affect the contract or the
work, and shall indemnify and save harmless the OWNER and ENGINEER against any claim arising from the violation of any such laws, ordinances, and regulations whether by the CONTRACTOR
or his employees, except wliere 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 ENGINEER in writing, and any necessary 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 OWNER
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 may enter into contract, shall be controlling, and shall be considered as part of this contract, to the same effect as though embodied herein. 3.16 ASSIGNMENT AND SUBLETTING.
The CONTRACTOR further agrees that he will retain personal control and will give his personal attention to the fulfillment of this contract and 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
OWNER. The CONTRACTQR 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 OWNER, as provided by this Agreement. 3.17 INDEMNIFICATION. The CONTRACTOR shall defend, indemnify and hold harmless the OWNER and the ENGINEER and their
resDective officers, agents and employees, from and against all damages, claims, losses, demands. suits, judgments and costs, including reasonable attorneys' fees and expenses, arising

disease or death or to injury to or destruction of tangible property (other than the work itself) including the loss of use resulting therefrom; and, G-7 
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 material actually furnished under this contract and the estimated
quantities contemplated and contained in the proposal; provided, however, that in case the actual quantity of any major item should become as much as 20% more than, or 20% less than
the estimated or contemplated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to 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 ® by Tu.u s..,<00", ASC£ 􀀱􀁾􀀷􀀱􀀠
5.04 PARTIAL PAYMENTS. On cir 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. Tbe OWNER sball then pay the CONTRACTOR on or before the 15th day of tbe 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 Curther 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 oC 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 CON· TRACTOR shall receive payment of the
balance due him under the contract subject only to the conditions stated under "Final Payment." 5.05 USE OF COMPLETED PORTIONS. The OWNER shall have the right to take possession of and
use any completed or partially completed portions of the work, notwithstanding the time for completing the entire work or such portions may not have expired but such taking possession
and use shall not be deemed an acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost of or delays the work, the CONTRACTOR
shall be entitled to such extra compensation, or extension of time, or both, as the ENGINEER may determine. The CONTRACTOR shall notify the ENGINEER when, in the CONTRACTOR'S opinion,
the contract is "substantially completed" and when so notifying the ENGINEER, the CONTRAC· TOR shall furnish to the ENGINEER in writing a detailed list of unfinished work. The ENGINEER
will review the CONTRACTOR'S list of unfinished work an«l 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 the Contract Documents,
the ENGINEER shall issue to the OWNER and the CONTRACTOR his Certificate of Completion, and thereupon 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 PAYMENT. Upon the issuance of the 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 oC the Agreement and shall
certify same to the OWNER, who shall pay to the CONTRACTOR on or after 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 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 by the CONTRACTOR. Neither the Certificate of Acceptance nor the final payment, nor any provision in the Contract Documents, shall relieve the CONTRACTOR oC the obligation
for fulfillment 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: G-lO 
(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 subcontractors
or for material or labor. (d) Damage to another con tractor. (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 CONTRACTOR of the sum
named in any partial or final statement, when payment is due, then the OWNER shall pay to the CONTRACTOR, in addition to the sum shown as due by such statement, interest thereon at the
rate of six (6) per 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 by the OWNER and recover compensation, as provided under "Abandonment of Contract," unless such payments
are withheld in accordance with the provisions of "Payments Withheld." 6. EXTRA WORK AND CLAIMS 6.01 CHANGE ORDERS: Without invalidating this Agreement, the OWNER may, at any time or
from time to time, order additions, deletions or revisions to the work; such changes will be authorized by Change Order to be prepared by the ENGINEER for execution by the OWNER and
the CONTRACTOR. The Change Order shall set forth the basis for any change in contract price, as hereinafter set forth for Extra Work, and any change in contract time which may result
from the change. In the event the CONTRACTOR shall refuse to execute a Change Order which has been prepared by the ENGINEER and executed by the OWNER, the ENGINEER may in writing instruct
the CONTRACTOR to proceed with the work as set forth in the Change Order and the CONTRACTOR may make claim against the OWNER for Extra Work involved therein, as hereinafter provided.
6.02 MINOR CHANGES: 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 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 the work involved may result in an increase in the 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-ll 
Method (A)-By agreed unit prices; or Method {B)-By agreed lump sum; or Method {C)-If neither Method (Al nor Method (Bl 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 aU 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" shaH be kept and the records of these accounts shall he made available to the ENGINEER. The ENGINEER or OWNER may also specify in writing, before the work commences,
the method of doing the work and the type and kind of machinery and equip· m2nt 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 ExpeTlse adopted
by the Associated General Contractors of America. Where practicable the terms and prices for the use of machinery and equipment shall be incorporated in the Written Extra Work Order.
The fifteen (15%) 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 writing 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 pxceptions 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
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 G·12
@by Tt__ Sffi,OA, ASCI'; ]911 
by the two arbiters so selected; or if tbe 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 precedent to any right of legal action. The dedsion of the arbiter or arbiters may be filed in court to carry it into effect. The arbiters, if
they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal,
and if the appeal was taken without reasonable cause, they may award damages for any delay occasioned thereby. The arbiters shall fix their own compensation, unless otherwise provided
by agreement, and shall assess the cost and charges of the arbitration upon either or both parties. The award of the arbiters must be made in writing. 7. ABANDONMENT OF CONTRACT 7.01
ABANDONMENT BY CONTRACTOR. 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 perfonnance 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 sball 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 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: 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
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 andlor 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. In 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 
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 andlor 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 andlor 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 andlor his Surety. Should the cost to complete the work exceed
the contract price, and the CONTRACTOR andlor 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 CONTRAGTOR 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 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 statea in ',he attached proposal
where unit 􀁰􀁲􀁩􀁣􀁥􀁾􀀠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 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. G-14

with the excavated materials, approved for backfilling, cons ting of earth, loam, sandy clay, sand and gravel, or other approved materials, free from large clods of earth or stones,
deposited in 6 inch (6") layers and thoroughly and carefully rammed until the pipe has a cover of not less than Z feet (2'). Trenches across roadways, along berms of roadways, or in
areas to be paved or subjected to traffic shall be entirely backfilled in 6-inch (6") layers, and each layer shall be compacted to a density at least equal to the density of the surrounding
earth, and the surface shall be graded to conform with the surrounding ground surface. Along all other portions of the trenches, unless otherwise specified or indicated on the Drawings,
the remainder of the backfill above the Z-foot (2') cover specified above shall be applied in I-foot (1') layers and properly compacted and the surface shall be mounded over and left
in a a uniform and neat condition satisfactory to the Engineer. 1 08 
. 1. Trenches improperly backfilled shall be re-opened to the depth required for proper compaction then refilled and compacted as specified, or the condition shall be otherwise corrected
as permitted by the Engineer. 7. 􀁾􀁴􀀠for Displacement of Sewers: Sewer mains will be checked by the Engineer to determine whether any displacement of the pipe has occurred after the
trench has been backfilled to 2 feet (2') above the pipe and tamped as specified. The test will be as follows: A light will be flashed between manholes, or, if the manholes have not
as yet been constructed, between the locations of the manholes, by means of a flashlight or by reflecting sunlight with a mirror. If the illuminated interior of the pipeline shows poor
alignment, displaced pipe, or any other defects, the defects designated by the Engineer shall be remedied by the Contractor at his expense. B. Pipe Laying: The bottom of the trench shall
be shaped to give substantially uniform circumferential support to the lower fourth of each pipe. pipe. Pipe laying shall proceed upgrade with the spigot ends of bell-and-spigot pipe
and tongue end of tongue-and-groove pipe pointing in the direction of flow. Each pipe shall be laid I,. ;'true to line and grade and in such manner as to form a close concentric joint
with the adjoining pipe and !i H to prev.nt sudden offsets of the flow line. As the 'i \"ork progresses, the interior of the sewer shall be !. cleared of all dirt and superfluous materials
of every description. Where cleaning after laying is difficuit because of small pipe size, a suitable swab or drag shall be kept in the pipe and pulled forward past each joint immediately
after the jointing has been completed. If the maximum width of the trench ! at the top of the pipe, specified above, is exceeded for any reason other than by direction, the Contractor
shall install, at no additional cost to the Owner, such concrete cradling, pipe encasement, or other bedding as may be required to satisfactorily support the added load of the backfill.
Trenches shall be kept free of water and pipe shall not be laid when the condition of the trench or the weather is unsuitable for such work. At time when work is not in progress, open
ends of pipe and fittings shall be securely and satisfactorily closed so that no trench water, earth, other substance will enter the pipe Or fittings. 1"􀁾􀀠1-09

Restoration of Site: After the backfill IS completed, the Contractor shall dispose of all surplus material, dirt, and rubbish from the site. The Contractor shall restore all disturbed
areas to their original condition. After 􀁾􀁬􀁬􀀠work is completed, the Contractor shall remove all tools and other equipment used by him, leaving the entire site free, clear, and in
good condition. Performance of the work described in this section is not payable directly, but shall be considered as a subsidiary obligation of the Contractor covered under the Contract
Unit Price for the pipe. F. Bedding Haterial: A six inch (6") layer of sand bedding material shall be placed belOW, around and above the pipe. The bedding material shall be accurately
graded to provide uniform bearing and support for each section of the pipe on and at every point along its entire length except for the portion of the pipe where it is necessary to excavate
for pipe joints. G. Backfill Material: Sand shall be placed around and overthe pIpe toa minimum depth of 6" above the top of the pipe. Select backfill containing no rocks larger than
6" at its longest part shall be placed in the trench and compacted by jetting. Backfilling and jetting shall continue until no settling occurs . I, .' ., , I. 1-11 i 
I 1-04 INFILTRATION AND EXFILTRATION TESTS Ii ILeakage into or out of the sewers, manholes and other structures shall not exceed a rate of 50 gallons per day per inch of diameter per
mile of sewer for any section between successive manholes. If in the opinion of the Engineer, infiltration appears excessive, the amount of leakage shall be measured by a suitable weir
or as directed by the Engineer at the Contractor's l. expense. When the infiltration exceeds the specified I' amount, correction shall be made to the satisfaction of the Engineer. In
addition to any infiltration test that may be required be the Engineer, the Contractor may Ibe required, at his own expense, to perform an exfiltration test on sections of piping 200
-300 feet long as selected by the Engineer. For this test, the lines shall be plugged on the upstream side of successive manholes and with all service connections plugged or capped,
the Contractor shall fill the line from the upstream manhole with water to a depth of 3 feet or more. The trench excavation shall remain dewatered as required throughout the te.st. Loss
of water from the upstream manhole during a 24-hour period shall not exceed the rate of 50 gallons per inch diameter per mile of sewer per day. " NOTE: Infiltration or exfiltration tests
will be required on all sewer lines. Air testing of all lines may be substituted for the ab6ve with the advance approval of the 􀁅􀁮􀁧􀁩􀁮􀁥􀁾􀁲􀀮􀀠Manholes will be tested by exfiltration.
