Likewise, the Contractor shall be solely responsible for the safety of himself, his employees and other persons, as well as for the protection of the safety of the improvements being erected and the property of himself or any other person, as a result of his operations hereunder. Engineering construction drawings and specifications as well as any additional information concerning the work to be performed passing from or through the Engineer shall not be interpreted as requiring or allowing Contractor to deviate from the plans and specifications, the intent of such drawings, specifications and any other such instruc- tions being to define with specificity the agreement of the parties as to the work the Contractor is to perform. Contractor shall' be fully and completely liable, at his own expense, for design, construction, installation and use, or non -use, of all items and methods incident to performance of the contract, and` for all loss, damage or injury incident thereto, either to person or property, including, without limitation, the adequacy of all temporary supports, shoring, bracing, scaffolding, machinery or equipment, safety precautions or devices, and similar items or devices used by him during construction.

The Contractor shall make any cor- rections required by the Engineer, file with him two corrected copies and furnish such other copies as may be needed. The Engineer's approval of such drawings or schedules shall not relieve the Contractor from responsibility for deviations from drawings or specifications, unless he has in writing called the Engineer's attention to such deviations at the time of submission, nor shall it relieve him from responsi- bility for errors of any sort in shop drawings or schedules. It shall be the Contractor's responsibility to fully and completely review all shop drawings to ascertain their effect on his ability to perform the required contract work in accordance with the plans and specifications and within the contract time. Such review by the Engineer shall be for the sole purpose of determining the sufficiency of said drawings GC-6 Per 7.1 75 1 1 1 1 1 1 1 1 1 fi 1 1 1 i 1 1 1 1 1 1 1 1 1 1 1 or schedules to result in finished improvements in conformity with the plans and specifications, and shall not relieve the Contractor of his duty as an independent contractor as previously set forth, it being expressly understood and agreed that the Engineer does not assume any duty to pass upon the propriety or adequacy of such drawings or schedules, or any means or methods reflected thereby. in rela- tion to the safety of either person or property during Contractor's performance hereunder. - 2.13 Preliminary Approval The Engineer shall not have the power to waive the obligations of this contract for the furnishing by the Contractor of good material, and of his performing good work as herein described, and in full accordance with the plans and specifications.

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 prepara- tion for the work as originally planned. 2.16 Inspectors The Engineer may provide - one (or morel field inspectors at the work site for the limited purpose of GC -7 observing the work in progress and reporting back to the Engineer on the extent, nature, manner and performance of the work so that the Engineer may more effectively perform his duties hereunder. Such inspectors may also communicate between Engineer and Contrator their respective reports, opinions, questions, answers and clarifications concerning the plans, specifications and work but shall be deemed the agent of the Contractor for all purposes in communicating such matters. Such inspector may confer with the Contractor or Contractor's superintendent concerning the prosecu- tion of the work and its conformity with the plans and specifications but shall never be, in whole or part responsible for, charged with, nor shall he assume, any authority or responsibility for the means, methods or manner of completing the work or of the superintendence of the work or of the Contractor's employees. It is expressly understood and agreed that any such inspector is not authorized by the Engi- neer or Owner to independently act for either or answer on behalf of either, any inquiries of the Con- tractor concerning the plans, specifications or work. No inspector's opinion; advice; interpretation of the plans or specifications of this contract; apparent or express approval of the means, methods or manner of Contractor's performance of work in progress or completed; or discovery or failure to discover or object to defective work of materials shall release Contractor from his duty to complete all work in strict accordance with the plans and specifications or estop the Owner or Engineer from requiring that all work be fully and properly performed including, if necessary, removal of defective or otherwise unaccep- table work and the re-doing of such work. 3.

Prosecution and Progress 4.01 Time and Order of Completion It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Con- tractor shall be allowed to prosecute his work at such times and seasons, in such order of precedence, and in such manner as shall be most conducive to economy of construction; provided, however.' that the order and the time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications, and within the time of com- pletion designated in the Proposal; provided, also, that when the Owner is having other work done, either by contract or by his own force, the Engineer may direct the time and manner of constructing the work done under this contract, so that conflict will be avoided and the construction of the various works being done for the Owner shall be harmonized. The Contractor shall submit, at such times as may reasonably be requested by the Engineer, schedules which shall show the order in which the Contractor proposes to carry on the work, with dates at which the Contractor will start the several parts of the work, and estimated dates of completion of the several parts. 4.02 Extension of Time Should the Contractor be delayed in the completion of the work by any act or neglect of the Owner or Engineer, or of any employee of either, or by other contractors employed by the Owner, or by changes ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoid- able cause or causes beyond the Contractor's control, or by any cause which the Engineer shall decide justifies the delay, then an extension of time shall be allowed for completing the work, sufficient to com- pensate for the delay, the amount of the extension to be determined by the Engineer, provided, however, that the Contractor shall give the Engineer prompt notice in writing of the cause of such delay. Pe.verse w other omcli.ticns will rot be justification= for extension of tine ai "C31axar Days" crntracts. 4.03 Hindrances and Delays No claims shall be made by the Contractor for damages resulting from hindrances or delays from any cause (except where the work is stopped by order of and for the convenience of the Owner) during the progress of any portion of the work embraced in this contract. In case said work shall be stopped by the act of the Owner, then such expense as in the judgment of the Engineer is caused by such stoppage of said work shall be paid by the Owner to the Contractor. 5. Measurement and Payment 5.01 Quantities and Measurements No extra or customary measurements of any kind will be allowed, but the actual measured and /or com- puted length, area, solid contents, number and weight only shall be considered, unless otherwise spe- cifically provided. - - 5.02 Estimated Quantities This agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approxi- mate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and the material furnished. - GC -13 Where payment is based on the unit price method, the Contractor agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contemplated and contained in the proposal; provided, however, that in case the actual quan- tity of any major item should become as much as 20% more than, or 20% less than the estimated or con- templated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a revised consideration upon the portion of the work above or below 20% of the estimated quantity. A "Major Item" shall be construed to be any individual bid item incurred in the proposal that has a total cost equal to or greater than five (5) per cent of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices. Any revised consideration is to be determined by agreement between the parties, otherwise by the terms of this Agreement, as provided under "Extra Work." 5.03 Price of Work In consideration of the furnishing of all the necessary labor, equipment and material, and the completion of all work by the Contractor, and on the completion of all work and on the delivery of all material em- braced in this Contract in full conformity with the specifications and stipulations herein contained, the Owner agrees to pay the Contractor the prices set forth in the Proposal hereto attached, which has been made a part of this contract. The Contractor hereby agrees to receive such prices in full for furnishing all material and all labor required for the aforesaid work, also for all expense incurred by him, and for well and truly performing the same and the whole thereof in the manner and according to this Agreement. 5.04 Partial Payments On or before the 1st day of each month, the Contractor shall submit to the Engineer a statement showing the total value of the work performed up to and including the 25th day of the preceding month. The state- ment shall also include the value of all sound materials delivered on the job site and to be included in the work all partially completed work whether bid as a lump sum or a unit item which in the opinion of the Engineer is acceptable. The Engineer shall examine and approve or modify and, approve such statement. The Owner shall then pay the Contractor on or before the 20th day of the current month the total amount of the approved statement, less 10 per cent of the amount thereof, which 10 per cent shall be retained until final payment, and further less all previous payments and all further sums that may be retained by the Owner under the terms of this Agreement. It is understood, however, that in case the whole work be near to completion and some unexpected and unusual delay occurs due to no fault or neglect on the part of the Contractor, the Owner may —upon written recommendation of the Engineer — pay a reasonable and equitable portion of the retained percentage to the Contractor: or the Contractor at the Owner's option, may be relieved of the obligation to fully complete the work and, thereupon, the Contractor shall receive payment of the balance due him under the contract subject only to the condi- tions stated under "Final Payment." . 5.05 Use of Completed Portions The Owner shall have the right to take possession of and use any completed or partially completed por- tions of the work, notwithstanding the time for completing the entire work or such portions may not have expired but such taking possession and use shall not be deemed an acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost of or delays the work, the Contractor shall be entitled to such extra compensation, or extension of time, or both, as the Engineer may determine. The Contractor shall notify the Engineer when, in the Contractor's opinion, the contract is "substan- tially completed" and when so notifying the Engineer, the Contractor shall furnish to the Engineer in writing a detailed list of unfinished work. The Engineer will review the Contractor's list of unfinished work and will add thereto such items as the Contractor has failed to include. The "substantial comple- tion" of the structure or facility shall not excuse the Contractor from performing all of the work under- " taken, whether of a minor or major nature, and thereby completing the structure or facility in accor- dance with the Contract Documents.

Neither the Certificate of Acceptance nor the final payment, nor any provision in the Contract Documents, shall relieve the Contractor of the obligation for fulfill- ment of any warranty which may be required. 5.08 Payments Withheld The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of: (a) Defective work not remedied or other obligations hereunder not done. (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 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 Contractor of the sum named in any partial or final state- ment, when payment is due, then the Owner shall pay to the Contractor, in addition to the sum shown as due by such statement, interest thereon at the rate of 6% per annum, unless otherwise specified, from date due as provided under 'partial payments' and 'final payments,' until fully paid, which shall fully liquidate any injury to the contractor growing out of such delay in payment. It is expressly agreed that delay by the Owner in making payment to the Contractor of the sum named in any partial or final statement shall not constitute a breach of this contract on the part of the Owner nor an abandonment thereof nor shall it to any extent or for any time relieve the Contractor of his obligations to fully and completely perform here- under. 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. Rev 1.1.15 GC -15 In the event the Contractor shall refuse to execute a Change Order which has been prepared by the Engineer and executed by the Owner, the Engineer may in writing instruct the Contractor to proceed with the work as set forth in the Change Order and the Contractor may make claim against the Owner for Extra Work involved therein, as hereinafter provided. . 6.02 Minor Changes The Engineer may authorize minor changes in the work not inconsistent with the overall intent of the Contract Documents and not involving an increase in Contract Price. If the Contractor believes that any minor change or alteration authorized by the Engineer involves Extra Work and entitles him to an in- crease in the Contract Price, the Contractor shall make written request to the Engineer for a written Field Order. In such case, the Contractor by copy of his communication to the Engineer or otherwise in writing shall advise the Owner of his request to the Engineer for a written Field Order and that work involved may result in an increase in the Contract Price. Any request by the Contractor for a change in Contract Price shall be made prior to beginning the work covered by the proposed change. 6.03 Extra Work It is agreed that the basis of compensation to the Contractor for work either added or deleted by a Change Order or for which a claim for Extra Work is made shall be determined by the unit prices upon which this contract was bid to the extent such work can be fairly classified within the various work item descriptions and for work items that cannot be so classified by one or more of the following methods: Method (A) By agreed unit prices; or Method (6) By agreed lump sum; or Method (C) If neither Method (A) nor Method (B) be agreed upon before the Extra Work is commenced, then the Contractor shall be paid the "actual field cost" of the work, plus fifteen (15) percent. In the event said Extra Work be performed and paid for under Method (C), then the provisions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost to the Contractor of all workmen, such as foreman, timekeepers, mechanics and laborers, and materials, supplies, trucks, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus , actual equipment, for the time actually employed or used on such Extra Work, plus actual transportay tion charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, including Social Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of premiums on Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property Damage and Workmen's Compensation, and all other insurance as may be required by any law or ordinance, or directed by the Owner, or by them agreed to. The Engineer may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made avail- able to the Engineer. The Engineer or Owner may also specify in writing, before the work commences, the method of doing the work and the type and kind of machinery and equipment to be used; otherwise these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be determined by using 100 per cent, unless otherwise specified. of the latest schedule of Equipment Ownership Expense adopted by the Associated General Contractors of America. Where practicable the terms and prices for the use of machinery and equipment shall be incor- porated in the Written Extra Work Order. The fifteen (15 %) per cent of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, general superintendence and field office expense, and all other elements of cost and expense not embraced within the "actual field cost" as herein defined, save that where the Contractor's Camp or Field Office must be maintained pri- GC -16 1 ;.1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 madly on account of such Extra Work; then the cost to maintain and operate the same shall be included in the "actual field cost." ' No claim for Extra Work of any kind will be allowed unless ordered in writing by the Engineer. In case any orders or instructions, either oral or written, appear to the Contractor to involve Extra Work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the Engineer for written order authorizing such Extra Work. Should a difference of opinion arise as to what does or does not constitute Extra Work, or as to the payment therefor, and the Engineer insists upon its performance, the Contractor shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as pro- vided under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to arbitration, as hereinbelow provided. 6.04 Time of Filing Claims It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Engineer within thirty (30) days after the Engineer has given any directions, order or instruction to which the Contractor desires to take exception. The Engineer shall reply within thirty (30) days to such written exceptions by the Contractor and render his final decision in writing. In case the Contractor should appeal from the Engineer's decision, any demand for arbitration shall be filed with the Engineer and the Owner in writing within ten (10) days after the date of delivery to Contractor of the Engineer's final decision. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to any claims by either party, except claims by Owner for defective work or enforcement of warranties and except as noted otherwise in the contract documents. 6.05 Arbitration All questions of dispute under this Agreement shall be submitted to arbitration at the request of either party to the dispute. The parties may agree upon one arbiter, otherwise, there shall be three, one named in writing by each party, and the third chosen by the two arbiters so selected; or if the arbiters fail to select a third within ten (10) days, he shall be chosen by a District Judge serving the County in which the major portion of the project is located, unless otherwise specified. Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of the Engineer shall be final and binding on him. Should the other party fail to choose an arbiter within ten (10) days, the Engineer shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take ex parte proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any questions submitted to arbitration under this contract shall be a condition precedent to any right of legal action. The decision of the arbiter or arbiters may be filed in court to carry it into effect. The arbiters, if they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the appeal was taken without reasonable cause, they may award damages for any delay occasioned thereby. The arbiters shall fix their own compensation unless otherwise provided 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 writ- ten notification from the Owner, or the Engineer, or if the Contractor fails to comply with the orders of GC -17 the Engineer, when such orders are consistent with the Contract Documents, then, and in that case, where performance and payment bonds exist, the Sureties on these bonds shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. After receiving said notice of abandonment the Contractor shall not remove from the work any machin- ery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under contract for the work, may be held for use on the work by the Owner or the Surety on the performance bond, or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefor (except when used in connection with Extra Work, where credit shall be allowed as provided for under Section 6, Extra Work and Claims), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. Where there is no performance bond provided or in case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for, within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (1) The Owner may thereupon employ such force of men and use such machinery, equipment, tools, materials and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said Con- tractor, and expense so charged shall be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said Contractor, then the Contractor and /or his Surety shall pay the amount of such excess to the Owner, or (2) The Owner under competitive bids, taken after notice published as required by law, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case there is any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract, such increase shall be charged to the Contractor and the Surety shall be and remain bound there- for. However, should the cost to complete any such contract prove to be less than would have been the cost to complete under this contract, the Contractor and /or his Surety shall be credited therewith. When the work shall have been substantially completed the Contractor and his Surety shall be so noti- fied and Certificates of Completion and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the contract accounts, certified to by the Engineer as being correct. shall then be prepared and delivered to the Contractor and his Surety, whereupon the Con- tractor and /or his Surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement, within fifteen (15) days after the date of such Certificate - of Completion. In the event the statement of accounts shows that the cost to complete the work is less than that which would have been the cost to the Owner had the work been completed by the Contractor under the terms of this contract; or when the Contractor and /or his Surety shall pay the balance shown to be due by them to the owner, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be turned over to the Contractor and /or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor and /or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract, provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either public or private sale, with or without notice, as the GC -18 1 1 1 1 1 1 1 1 1 1 Owner may elect. The Owner shall release any machinery, equipment. tools, materials, or supplies, which remain on the work, and belong to persons other than the Contractor or his Surety, to their proper owners. The books on all operations provided herein shall be opened to the Contractor and his Surety. 7.02 Abandonment by Owner In case the Owner shall fail to comply with the terms of this contract, and should fail to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools and equipment, and all materials on the site of work that have not been included in payments to the Contractor and have not been wrought into the work. And thereupon the Engineer shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Contractor (at the prices stated in the attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable price. and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion and which cannot be utilized. The Engineer shall then make a final statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this Agreement and shall certify same to the Owner who shall pay to the Contractor on or before thirty (30) days after the date of the notification by the Contractor the balance shown by said final statement as due the Contractor, under the terms of this Agreement. 8. Subcontractors 8.01 Award of Subcontracts for Portions of the Work Unless otherwise specified in the Contract Documents or in the Instructions to Bidders, the Contractor, as soon as practicable after the award of the Contract. shall furnish to the Engineer in writing for accep- tance by the Owner and the Engineer a list of the names of the Subcontractors proposed for the' principal portions of the work. The Engineer shall promptly notify the Contractor in writing if either the Owner or the Engineer, after due investigation, has reasonable objection to any Subcontractor on such list and does not accept him. Failure of the Owner or Engineer to make objection promptly to any Sub- contractor on the list shall constitute acceptance of such Subcontractor. The Contractor shall not contract with any Subcontractor or any person or organization (including those who are to furnish materials or equipment fabricated to a special design) proposed for portions of the work designated in the Contract Documents or in the Instructions to Bidders or, if none is so desig. nated, with any Subcontractor proposed for the principal portions of the work who has been rejected by the Owner and the Engineer. The Contractor will not be required to contract with any Subcontractor or person or organization against whom he has a reasonable objection. If the Owner or Engineer refuses to accept any Subcontractor or person or organization on a list sub. mitted by the Contractor in response to the requirements of the Contract Documents or the Instructions to Bidders, the Contractor shall submit an acceptable substitute and the Contract amount shall be increased or decreased by the difference in cost occasioned by such substitution and an appropriate change order shall be issued; however. no increase in the Contract amount shall be allowed for any such substitution unless the Contractor has acted promptly and responsively in submitting for acceptance any list or lists of names as required by the Contract Documents or the Instructions to Bidders. If the Owner or the Engineer requires a change of any proposed Subcontractor or person or organization previously accepted by them, the Contract amount shall be increased or decreased by the difference in cost occasioned by such change and an appropriate Change Order shall be issued. The Contractor shall not make any substitution for any Subcontractor or person or organization who has been accepted by the Owner and the Engineer, unless the substitution is acceptable to the Owner and the Engineer. 'GC-19 8.02 Subcontractuai Relations All work performed for the Contractor by a Subcontractor shall be pursuant to an appropriate' written agreement between the Contractor and the Subcontractor land where appropriate between Subcontrac- tors and Sub - subcontractors) which shall contain provisions that: (1) preserve dto protect the rights of the Owner b p under der the subcontract sEngineer hat he subcontracting B hereof respect the work ill not prejudice such rights; (2) require that such work be performed in accordance with the requirements of the Contract Docu- ments; (3) require submission to the Contractor of the applications for payment under each subcontract , to which the Contractor is a party, in reasonable time to enable the Contractor to apply for payment in accordance with this contract; (4) require that all claims for additional costs, extensions of time, damages for delays or otherwise with respect to subcontracted portions of the work shall be submitted to the Contractor (via any Subcontractor or Sub - subcontractor where appropriate) in sufficient time so that the Contractor may comply in the manner provided in the Contract Documents for like claims by the Contractor upon the Owner, (5) obligate each subcontractor specifically to consent to the provisions of this section. A copy of all such Subcontract Agreements shall be filed by the Contractor with the Engineer before the Subcontractor shall be allowed to commence work. 8.03 Payments to Subcontractors The Contractor shall pay each Subcontractor, upon receipt of payment from the Owner, an amount directly based upon the value of the work performed and allowed to the Contractor on account of such Subcontractor's work, less the percentage retained from payments to the Contractor. The Contractor shall also require each Subcontractor to make similar payments to his subcontractors. If the Engineer fails to approve a payment for any cause which is the fault of the Contractor and not the fault of a particular Subcontractor, the Contractor shall pay the Subcontractor on demand, made at any time after the Certificate for Payment should otherwise have been issued, for his work to the extent corn• pleted, less the retained percentage. The Engineer may, on request and at his discretion, furnish to any Subcontractor, if practicable, information regarding percentages of completion certified to the Contractor on account of work done by such Subcontractors. Neither the Owner nor the Engineer shall have any obligation to pay or to see to the payment of any moneys to such Subcontractor except as may otherwise be required. 9. Separate Contracts 9.01 Owner's Right to Award Separate Contracts The Owner reserves the right to award other contracts in connection with other portions of the project under these or similar conditions of the Contract. When separate contracts are awarded for different portions of the Project. "The Contractor" in the contract documents in each case shall be the contractor who signs each separate contract. 9.02 Mutual Responsibility of Contractors The Contractor shall afford other contractors reasonable opportunity for the introduction and storage of their materials and equipment and the execution of their work, and shall properly connect and coor- dinate his work with theirs. GC•20 1 1 1 1 1 1 1 If any part of the Contractor's work depends for proper execution or results upon the work of any other separate contractor, the Contractor shall inspect and promptly report to the Engineer any apparent discrepancies or defects in such work that render it unsuitable for such proper execation and results. Failure of the Contractor so to inspect and report shall constitute an acceptance of the other contractor's work as fit and proper to receive his Work, except as to defects which may develop in the other separate contractor's work after the execution of the Contractor's Work. Should the Contractor cause damage to the work or property of any separate contractor on the project, the Contractor shall, upon due notice, settle with such other contractor by agreement or arbitration, if he will so settle. If such separate contractor sues the Owner or initiates an arbitration proceeding on account of any damage alleged to have been so sustained, the Owner shall notify the Contractor who shall defend such proceedings at the Contractor's expense, and if any judgment or award against the Owner arises therefrom the Contractor shall pay or satisfy it and shall reimburse the Owner for all attorney's fees and court or arbitration costs which the Owner has incurred. 9.03 ,Cutting and Patching under Separate Contracts The Contractor shall be responsible for any cutting, fitting and patching that may be required to com- plete his work except as otherwise specifically provided in the Contract Documents. The Contractor shall not endanger any work of any other contractors by cutting, excavating or otherwise altering any work and shall not cut or alter the work of any other contractor except with the written consent of the Engineer. Any costs caused by defective or ill -timed work shall be borne by the party responsible therefor. 1 10., Protection of Persons and Property - I 10.01 Safety Precautions and Programs - The Contractor shall be responsible for initiating, maintaining and supervising all safety precautions and programs in connection with the work. 1 10.02 Safety of Persons and Property 1 The Contractor shall take all reasonable precautions for the safety of, and shall provide all reasonable protection to prevent damage, injury, or loss to: (1) all employees on the work and all other persons who may be affected thereby; 1 (2) all the work and all materials and equipment to be incorporated therein. whether in storage or or off the site, under the care, custody or control of the Contractor or any of his Subcontractors or Sub - Subcontractors; and ' (3) other property at the site or adjacent thereto, including trees, shrubs, (awns, walks, pave- ments, fences, roadways, structures and utilities not designated for removal, relocation or replacement in the course of construction. The Contractor shall comply with all applicable laws, ordinances, rules, regulations and lawful orders of 1 any public authority having jurisdiction for the safety of persons or property or to protect them from damage, injury or loss. He shall erect and maintain, as required by existing conditions and progress of the work, all reasonable safeguards for safety and protection, including posting danger signs and other I warnings against hazards, promulgating safety regulations and notifying owners and users of adjacent utilities. When the use or storage of explosives or other hazardous materials or equipment is necessary for the I execution of the work, the Contractor shall exercise the utmost care and shall carry on such activities under the supervision of properly qualified personnel. 1 a•. 7.1 75 GC -21 1 AU Blasting, including methods of storing and handling explosives and highly inflammable materials, shall conform to Federal, State. Local Laws and Ordinances. All City Ordinances shall be complied with even though some or all of the blasting is done outside the City Limits unless the applicable Ordinance is in conflict with the law of the jurisdiction where the action is being taken. The following is a list of requirements in addition to Federal, State, and Local Laws and Ordinances. 1. The Contractor shall furnish the City of Austin with a Certificate of Blasting Insurance in the amount of $300,000.00 for each contract, at least twenty -four hours prior to using explosives. A blasting permit must be obtained from the City at least five (5) days prior to use of explo- sives. If Blasting is covered under the Contractor's General Insurance Certificate for each • contract, a separate blasting certificate will not be required. 2. The following public utility companies and City Department will be notified bythe Contractor, on every occasion, at least twenty -four (24) hours prior to the use of explosives: Water and Wastewater, Electric, Gas, Telephone and the City Engineering Department. 3. Explosive materials to be used shall be limited to blasting agents and dynamite, unless prior ap- proval of other materials is obtained in writing from the Engineering Department. 4. During blasting, all reasonable precautions shall be taken to protect pedestrians, passing vehicles, and public or private property. Blasting mats or protective cover shall be used when required by the City Inspector, the permit. or by safe blasting practices. 5. All explosives shall be stored in accordance with Chapter 38, Article 11. Section 38 11201. of the City Code. 6. The Director of Engineering or his representative shall have the right to limit the use of explosives and /or blasting methods which in his opinion are dangerous to the public or nearby property of any kind. 7.

The stockpile shall be constructed utilizing equipment such as a scraper, a bottom dump or other acceptable equipment that allows spreading when dumped without rehandling. The stockpile shall be constructed to allow dump spreading in 1 direction only. Height of stockpile shall not exceed the capabilities of available machinery to make a full cut (bottom to top) on any of the 4 sides. The City will test a completed stockpile. The stockpile shall not be added to after it has been tested. The Contractor shall assure that only material from a City approved stockpile receives a weight ticket indicating an approved stockpile number. The liability for accuracy of the weight ticket, as to items such as stockpile number or an approved source, is solely that of the Contractor. Use lull height cuts and mix the material during loading operations. -- The Inspector shall be given a weigh ticket at the time of delivery indicating the source, stockpile approval number and weight. (2) Test Sampling - The Contractor may choose the method of sample gathering for testing by City Testing Consultants as follows: (a) The Contractor shall make a full height cut from each side of the stockpile. The 4 samples are then Page 1 04/17/86 210 210.4 Construction Methods combined and mixed into a single "test" specimen from which the City's Testing Consultant can draw its samples. (b) As the stockpile is constructed, a perpendicular cut is to be made across the spreading direction at every 2 feet to 4 feet of height and the sample used to start a "mini' stockpile. Repeat the process, in 2 feet to 4 feet increments of heights, until the stockpile and the "mini" stockpile are completed: The Contractor shall provide access to samples from the "mini" stockpile for the City's Testing Consultant to draw its samples. (1) Preparation of Subgrade "Flexible Base" shall not be placed until the Contractor has verified, by proof rolling, that the subgrade has been prepared and compacted in conformity with Item No. 201, "Subgrade Preparation" to the typical sections, lines and grades indicated. Any deviation shall be corrected and proof rolled prior to placement of aggregate. Blue tops shall be set by the Contractor for subgrade on centerline, quarter points, curb lines or edge of pavement where curb is omitted, at intervals not exceeding 50 feet. Subgrade shall be tested by proof rolling in conformity with Item No. 236, "Rolling (Proof)" prior to placing first course of base material. (2) First Course Immediately before placing the base material, the subgrade shall be checked as to conformity with grade and sec- tion. The thickness of each base course shall not exceed 6 inches, loose measure and will be equal increments of the total depth. The material shall be delivered in approved vehicles and it shall be the responsibility of the Contractor that the re- quired amount of specified material shall be delivered. Material deposited upon the subgrade shall be spread and shaped the same day unless otherwise approved by the Engineer. In the event inclement weather or other unfore- seen circumstances render impractical spreading of the material during the first 24 hour period, the material shall be spread as soon as conditions allow. The material shall be sprinkled, if required, and shall then be bladed, dragged and shaped to conform to typical sections as indicated. All areas and "nests" of segregated course or fine material shall be corrected or removed and replaced with well graded material. If additional binder is considered desirable or necessary after the material is spread and shaped, it shall be furnished and applied as required. Such binder mate- rial shall be carefully and evenly incorporated with the material in place by scanfying, harrowing, brooming or by other approved methods. The course shall be sprinkled as required to bring it to optimum moisture content and compacted to the extent nec- essary to provide not less than the percent density as hereinafter specified under "Density ". In no case shall the base be worked at more than 2 percent above or below optimum moisture. In addition to the requirements specified for density, the full depth of flexible base indicated shall be compacted to the extent necessary to remain firm and stable under construction equipment. After each section of flexible base is completed, tests as necessary will he made by the Engineer. If the material fails to meet the density requirements, it shall be reworked as necessary to meet these requirements. Throughout this entire operation the shape of the base course shall be maintained by blading and the surface, upon completion, shall be smooth and in conformity with the typical section indicated and to the established lines and grades. In that area on which pavement is to be placed, any deviation in excess of V. inch in cross section and in length of 16 feet measured longitudinally shall be corrected by loosening, adding or removing material, reshaping and recompacting by spnnkting and rolling. All irregularities, depressions or weak spots which develop shall be corrected immediately by scarifying the areas affected, adding suitable material as required, re- shaping and recompacting by sprinkling and rolling. Should the base course, due to any reason or cause. lose the required stability, density and finish before the surfacing is complete, it shall be recompacted and refinished at the sole expense of the Contractor. (3) Succeeding Courses Construction methods shall be the same as prescribed for the first course. Blue tops shall be set by the Contractor for finished grade on the last course of base under curb and gutter, at a maximum of 50 foot intervals. Blue tops shall also be set by the Contractor for finished base grade on centerline, intermediate points not exceeding 11 feet be- tween points and at pavement edge if curb and gutter are not included in the work, at 50 foci intervals. (4) Density Each course of flexible base shall be compacted to not less than 100 percent density when tested in accordance with SDHPT Test Method Tex - 113 -E. Field density determination shall be made in accordance with approved methods. The completed Flexible Base shall be tested by proof rolling in conformity with Item No. 236.

The mixture when discharged from the plant surge storage bin shall have a moisture content not greater than 1 percent by weight and must be of equal quality to that coming out of the mixer. The moisture content shall be determined in accordance with SDHPT Test Method Tex- 212 -F, Part II. 340.8 Construction Methods II shall be the responsibility of the Contractor to produce, transport, place and compact the specified paving mixture in accor- dance with these specifications and provide a safe environment to enable inspection forces to lake samples and check the plant. Prior to placing HMAC, the base shall be proof rolled and any soft spots repaired and the area proof rolled again. The asphaltic mixture, when placed with a motor grader for leveling, shall not be placed when air temperature is below 50 F and falling. The air temperature shall be taken in the shade away from artificial heat. Mat thickness of 11/2 inches and less shall not be placed when the temperature of the surface on which the mat is to be placed is below 50 F. All asphaltic mixture, except that descnbed above for leveling, shall be placed with a spreading and finishing machine. II, after being discharged from the mixer and prior to placing, the temperature of the asphaltic mixture is 50 F or more below the tempera- ture established, all or any part of the load may be rejected and payment will not be made for the rejected material. Any material placed which is too cool to compact properly shall be removed and replaced with material which meets the specifications. Adjacent to flush curbs, gutters, liners and structures, the surface shall be finished uniformly high so that when compacted it will be slightly above the edge of the curb and flush structure. The compacted thickness of the asphaltic concrete courses shall be as indicated. Where the thickness of the surface course Is specified to be more than 2 inches, the work shall be accomplished in equal lifts, unless otherwise indicated. When the surface is to be constructed in stages and traffic is permitted on the initial layer, each layer shall be not less than 1 inch. The final lift of HMAC shall not be placed adjacent to an existing cured rounded edge asphalt surface until the existing surface has been prepared. Page 5 04/17/86 340 .

The asphaltic concrete shall not be applied on a previously primed flexible base until the primed base has cured to the satisfaction of the Engineer. (2) Tack Coat If a tack coat is indicated, it shall be applied conforming to Item No. 307, "Tack Coat ". Before the asphaltic mixture is placed. the surface upon which the tack coat is to be placed shall be cleaned thoroughly to the satisfaction of the Engineer. The surface shall be given a uniform application of tack coat using asphaltic materials of this specification. This tack coat shall be applied, as directed by the Engineer. Where the mixture will adhere to the surface of which it is to be placed without the use of a tack coat, the tack coat may be eliminated by the Engineer. All contact surfaces of curbs and structures and all joints shall be painted with a thin uniform coat of the asphaltic material meeting the requirements for tack coat. The tack coat shall be rolled with a light pneumatic tire roller when directed by the Engineer. (3) Compacting The mix shall be compressed thoroughly and uniformly compacted immediately after placing to the required density. All compaction rolling shall be complete before the mat cools below 175 F. Minor polishing rolling may be undertaken on the mat below the above temperature. All rollers must be in good mechanical condition. Necessary precautions shall be taken to prevent the dropping of gasoline, oil, grease or other foreign matter on the pavement, either when the rollers are in operation or when standing. It is the intent of this specification that the material be placed and compacted to a minimum of 92.5 percent of the maximum theoretical density as determined by SDHPT Tex - 227 -F. The Engineer will secure 6 inch core samples or sections of completed asphaltic pavement lifts for approximately every 2,000 square yards or part thereof, of asphaltic concrete pavement placed. The In place density at the sampled locations shall be determined by the fol- lowing equation: Percent in place Density = GA x 100 T Where GA = Bulk specific gravity of core when tested in accordance with Tex -207 -F GT = Maximum theoretical specific gravity of combined cores when tested in accordance with Tex -227 -F The Contractor shall patch the surface where specimens are taken with no extra payment being made for this work. The Engineer will remove the asphaltic concrete pavement specimen on the day following placement or as soon as practicable thereafter. Other methods of determining in place density which correlate satisfactorily with those results obtained by cores or sections may be used. The initial sampling and testing of in place asphalt concrete will be at no cost to the Contractor, except for the cost of material and restoration of damage by testing. Retesting expense will conform to Section 00344, "Testing Labora- tory Services ". (4) Surface Tests The surface of the pavement, after compaction, shall be smooth and true to the established line, grade and cross section, and when tested with a 10 foot straightedge placed parallel to the centerline of the roadway or tested by other equivalent and acceptable means, except as provided herein, the maximum deviation shall not exceed Va inch in 10 feet and any point in the surface not meeting this requirement shall be corrected. The completed surface shall meet the approval of the Engineer for riding surface, finish and appearance. (5) Opening to Traffic The pavement shall be opened to traffic as soon as possible after temporary pavement markings or permanent pavement markings are in place as Indicated and the Engineer concurs to the opening. The Contractor's attention is directed to the fact that all construction traffic allowed on pavement open to the public will be subject to the City Ordinances and State Laws governing traffic on streets and highways. Surface raveling, cracking, segregation and other defects shall be corrected at the Contractors expense as directed by the Engineer. Traffic control expense for undertaking the repairs will be at the Contractor's expense. 340 04/17/86 Page 6 340.9 Acceptance Plan (1) General The surface testing shall be completed prior to the use of pay adjustment factors for acceptance of gradation, as- phalt content, stability, In place density and pavement thickness. The pay adjustments will be based upon the results of tests performed on samples taken in a random manner. Pay adjustment for private development work shall con- form to Item No. 1804, "General Obligations and Responsibility of the Owner ". (a) Sampling The Engineer will determine the sampling schedules for random testing in accordance with SDHPT Test Method Texa225 -F. Samples will be taken at the plant or on the project site, as determined by the Engineer. The Engineer may require that either cores or sections of asphaltic pavement be taken at locations selected by the Engineer. (b) Testing Determination of acceptability will be based on tests performed by the City or Its laboratory. However, truck loads of the asphaltic mixture that are visually inspected by the Engineer and can reasonably be expected not to meet specification requirements, such as a mixture containing segregated material, low mixture tempera- ture, a deficiency or excess of asphalt, or otherwise unsuitable for placing on the roadway shall not be used. Any mixtures containing segregated areas, deficiency or excess of asphalt or otherwise unsuitable that is placed on the roadway shall be removed and replaced with satisfactory material at the Contractor's expense. Acceptability will be based on the mean of the job values from the City tests of the project materials. (2) Gradation and Asphalt Content The acceptability of mixture gradation and asphalt content will be based on the mean of a minimum of 3 tests taken by the City's laboratory. If the mean value of acceptance tests of the project, for a particular sieve or sieves or for asphalt content deviates from the project design by more than the tolerances shown and the Engineer determines that the material need not be removed and replaced, the project may be accepted at a reduced Contract Unit Price as follows: SPECIFIED DEVIATION OF THE PERCENT CONTRACT UNIT SEIVE SIZE MEAN FROM THE DESIGN PRICE REDUCTION Passing 'h inch 0 — 5.0 0 5.1 + 5 Passing 3a inch, 3'a inch 0 — 5.0 0 to #4, 5.1 — 7.0 2 #4 to #10, Total retained on #10 7.1 + 4 #10 to #40, #40 to #80, 0 — 5.0 0 5.1 + 5 Passing #200 0 — 5.1 ' 0 3.1 +, '5 ASPHALT CONTENT ACCEPTANCE SCHEDULE PERCENT DEVIATION FROM INTENDED ASPHALT CONTENT GRADATION ACCEPTANCE SCHEDULE PERCENT CONTRACT UNIT PRICE REDUCTION 0 - 0.3 0 0.31 -0.4 10 0.41 -0.5 20 over 0.5 100 and the Engineer may require a seal coat or removal and replacement at Contractor's expense.

When the Contractor installs a pipe that crosses over a utility structure or storm sewer and the top of the utility structure or storm sewer and the top of the utility structure is within 18 inches of the bottom of the pipe, the pipe shall be either Ductile Iron or PVC, unless otherwise specified by the Engineer. (4) Trench Excavation Unless otherwise indicated, at underground piped utilities shall be constructed in an open cut with vertical sides from the bottom of the bedding to a point 1 foot above the pipe with a minimum trench width of 6 ". (Defined as the pipe zone.) The excavation above this point may be stepped and/or the sides laid back to a stable slope. Required vertical sides shall be sheeted and braced to the extent necessary to maintain the sides of the required vertical excavation throughout the construction period. Adequacy of the sheeting and bracing shall be the responsibility of the Contractor but shall be subject to review by the Engineer. After the pipe has been laid and the backbit placed and compacted to 12 inches above the top of the pipe, any sheeting, shoring and bracing required may be removed with special care to insure that the pipe is not disturbed. As each piece of sheeting is removed, the space left by its removal must be thoroughly filled and compacted with suitable material and provision made to prevent the sides of the trench from caving until the backfill has been completed. Any sheeting left in place will not be paid for and shall be considered subsidiary to the pipe item bid. (5) Trench Width Trenches for water and wastewater lines shall have a minimum width of 6 inches and a maximum width of 1 foot on each side beyond the outside surfaces of the pipe bell or coupling. Trenches for Storm Sewers up to 42 Inches shall have a width of 1 foot on each side beyond the outside surfaces of the pipe. Pipes more than 42 inches shall have a trench width not to exceed 18 inches on each side beyond the outside surfaces of the pipe. • If trench width within the pipe zone exceeds this maximum, the entire pipe zone shall be refilled with approved backfill malenal. thoroughly compacted to a minimum of 95 percent of maximum density as determined by SDHPT Test Method Tex -114 -E and then re- excavated to the proper grade and dimensions. Excavation along curves and bends shall be so oriented that the trench and pipe are approximately centered on the centerline of the curve, using short links of pipe and/or bend fillings if necessary. 510 04/17/86 Page 22 The wastewater line may be placed no closer than 6 inches from the water line. The separation distance must be measured between the nearest outside pipe diameters. The wastewater line shall be located at a lower elevation than the water line wherever possible and one length of the wastewater line must be centered on the water line. Unless wastewater manholes and the connecting sewer can be made completely watertight and tested for no leakage, they must be installed so as to provide a minimum of 9 feet of horizontal clearance from an existing or proposed water line. Where a new wastewater force main parallels or crosses a water main, that portion of the force main which is within 9 feet of the water line shall be constructed of ductile iron or PVC meeting AWWA C -900 specifications. For all utilities to be constructed in fill above natural ground, the embankment shall first be constructed to an eleva- tion not less than 1 foot above the top of the utility after which excavation for the utility shall be made as indicated.

Service stubs installed on the existing system shall be installed by use of tapping saddles unless otherwise approved by the Engineer. Extreme care shall be exercised to prevent material from depositing in the existing pipe as the taps are being made. When connections to existing mains are made, a temporary plug approved by the Engineer must be installed downstream in the manhole to prevent water and debris from entering the existing system before final accep- tance. These plugs shall be removed after the castings are adjusted to finish grade or when final acceptance is given. (24) Water System Connections The Contractor shall, at his expense, make all necessary connections of new piping or accessories to the existing water system. To minimize any inconvenience from outages, the Contractor shall schedule all such connections in advance and such schedule must be approved by the Superintendent of Water Division before beginning arty work. (a) Shutoffs The City will make all shutoffs on existing water mains where more than one valve is involved. The Contractor will be required to notify the Engineer's field representative on the job at least 24 hours prior to the desired time for any shutoff. Where only one valve will be operated, the Contractor may operate the valve under the imme- diate supervision of the Engineer's field representative. - (b) Wet Connections to Existing Water System The Contractor shall make all wet connections called for by the Contract or required to complete the work. A wet connection shall include draining and cutting into existing piping and connecting a new pipeline or other extension into the existing pressure piping, forming an addition to the water transnission and distribution network.

Direct tap- ping will not be permitted. All service connections shall be Installed so that the outlet is at an angle of approximately 45 degrees above honzontal at the main line. 510 04/17/86 Page 30 1 1 1 1 1 1 1 1 . 1 1 1 1 1 1 1 1 1 1 Precautions should be taken to ensure that the tapping saddle or sleeve is placed on the pipe straight to pre- vent any binding or deformation of the PVC pipe. The mounting chain or U -bolt strap must be tight. Tapping shall be performed with a sharp shell type cutter so designed that it will smoothly penetrate heavy walled PVC DR14 and 200 psi AC and will retain and extract the coupon from the pipe. (25) Backfitling (a) General After the pipe has been bedded, laid, jointed, approved and any bedding envelope placed, backfilling shall be done immediately in accordance with the details indicated, with approved material, except that when mortar joints are used for jointing storm sewers, no backfill above the bedding shall be placed, until the mortar has cured for at least 6 hours. During backfilling operations, no heavy equipment which might damage the pipe will be allowed until a mini- mum cover of 12 inches above the top of pipe is obtained. During the backfilling operations. special emphasis is placed upon the need for obtaining uniform backf111 ma- terial and uniform compacted density throughout the length and depth of the structure. Extreme care is to be taken to insure proper backfill over the pipe. The maximum lift of backfill shall be determined by the equipment selected and in no case shall it exceed 18 inches, loose measurement. All backfill in streets and under structures will be tested by the City and must satisfy the specified density requirements conforming to Section 00344, "Testing Laboratory Services" before final acceptance. (b) General Corrugated Metal Pipe After the corrugated metal pipe structure has been completely assembled on the proper line and grade and headwalls constructed when indicated, selected material free from rocks over 8 inches in size from excavation or borrow, as approved by the Engineer, shall be placed along both sides of the completed structures equally, in uniform layers not exceeding 6 inches in depth (loose measurement), sprinkled if required and thoroughly compacted between adjacent structures and between the structures and the sides of the trench or for a dis- tance each side of the structures equal to the diameter of the pipe if pipe is laid above the existing ground. Backfill material shall be compacted to the same density requirements as indicated for the adjoining sections of embankment in accordance with the governing specifications thereof. Above the 3/4 point of the structure, the fill shall be placed uniformly on each side of the pipe in layers not to exceed 12 inches, loose measure Prior to adding each new layer of loose backfill material, until a minimum of 12 inches of cover is obtained over the crown of the pipe, an inspection will be made of the inside periphery of the corrugated metal structure to determine if any floating, local or unequal deformation has occurred as a result of improper construction methods. (c) Backfill Materials The Engineer may approve any of the following well graded materials: 1. Select trench material 2. Sand 3. Crushed rock cuttings 4. Rock cuttings - 5. Foundation Rock 6. Blasted material with fines and rock 7. Cement stabilized material 8. Borrow Within the 100 year flood plan sand will not be permitted for bedding or backfilling. The Engineer shall approve the topsoil for areas to be seeded or sodded. (d) Backfill in Street Right of Way Placement of backlit! under structures and within 2 feet of structures shall be compacted to the required den- sity using any method, type and size of equipment which will give the required compaction without damaging Page 31 04117186 -1 510 I , the pipe or bedding. The depth of layers, prior to compaction, shall depend upon the type of sprinkling and compacting equipment used and the test results thereby obtained. Prior to and in conjunction with the com- paction operation, each layer shall be brought to the moisture content necessary to obtain the required density and shall be kept leveled to Insure uniform compaction over the entire layer. Testing for density will be in accor- dance with Test Method Tex -114 -E and Test Method Tex - 115 -E. Each layer of backfill must provide the density as required herein. Swelling soils (soils with plasticity index 0120 or more) shall be sprinkled as required to provide not less than optimum moisture nor more than 2 per- cent over optimum moisture content and compacted to the extent necessary to provide not less than 95 per - cent nor more than 102 percent of the density as determined in accordance with Test Method Tex - 114 -E. Nonswelling soils (soils with plasticity index less than 20) shall be sprinkled as required and compacted to the extent necessary to provide not less than 95 percent of the density as determined in accordance wits Test Method Tex - 114 -E. After each layer of backfill is complete, tests may be made by the Engineer. If the material fails to. meet the density indicated, the course shall be reworked as necessary to obtain the indicated compaction and the com- paction method shall be altered on subsequent work to obtain indicated density and conform to Section 00344, "Testing Laboratory Services ". At any time, the Engineer may order proof rolling to test the uniformity of compaction of the backfill layers. All irregularities, depressions, weak or soft spots which develop shall be corrected immediately by the Contractor. Should the backfill, due to any reason or cause, lose the required stability, density or finish before the pave- ment structure is placed, it shall be recompacted and refinished at the sole expense of the Contractor. Exces- sive loss of moisture in the subgrade shall be prevented by sprinkling, sealing or covering with a subsequent backfill layer or granular material. Excessive loss of moisture shall be construed to exist when the subgrade soil moisture content is more than 4 percent below the optimum of compaction ratio density. Backfill shall be placed from the top of the bedding material to the existing grade, base course, subgrade or as indicated. The remainder of the street backfill shall be Flexible Base, Concrete or Hot Mix Asphalt Concrete as indicated or to replace in kind the surface removed to construct the pipe. (e) Backlit! in County Street or State Highway Right of Way All work within the right of way must meet the requirements of (d) above, as a minimum anc shall meet the requirements of the permit issued by the County when their requirement are more stringent. F'rior to the start of construction, the Contractor will be responsible for contacting the appropriate SDHPT olice or County Commissioner's Precinct Office and for coordinating his activities with the operating procedures in effect for utility cut permits and pavement repair under their jurisdiction. Approval for all completed work in the State or County right of way must be obtained from the appropriate Official prior to final payment by the Owner. (1) Backfill in Railroad Right of Way All work within the railroad right of way must meet the requirements of (d) above, as a minimum and shall meet the requirements of the permit issued by the Railroad Owner when (heir requirements are more stringent. Approval for all completed work in the railroad right of way must be obtained from the Railroad prior to final acceptance. (g) Backfill in Easements Where not otherwise indicated, all backfill in easements across dedicated parkways, planting spaces, under or adjacent to utilities, structures, etc., shall satisfy all the requirements for backfill in streets or under structures. Where there are no requirements for density, the Contractor may select whatever methods and procedures may be necessary to restore the entire work area to a safe, useful and geologically stable condition satisfac- tory to the Engineer and generally equal or superior to the conditions prior to construction. In and near the flood plain of all streams and watercourses and on all slopes subject to erosion by runoff, all backfill shall be compacted to at least 95 percent of maximum dry density as for street right of way, unless otherwise directed by the Engineer. All soil areas disturbed by the construction shall be covered with top soil and seeded conforming to Item No. 604, "Seeding for Erosion Control ". All turf, drainways and drainage structures shall be constructed or re- placed to their original condition or better. No debris shall remain in the drainways or drainage structures. (26) Quality Testing for Installed Pipe (a) Wastewater Pipe Acceptance Testing After the construction is complete, the Engineer shall determine whether the pipeline is to be tested for.nfiltra- lion and exfiltration by the low pressure air test method. 510 04/17/86 Page 32 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Wastewater pipe installed in the City of Austin and its ETJ areas shall be tested for exfiltration and infiltration as described below in " Exfiltration Test" and "Infiltration Test" or by acceptable low pressure air test, as de- scribed below. At the conclusion of either test series, the work shall be further tested for pipeline settlement as described below. The Contractor shall be solely responsible for making proper structural repairs to those ele- ments which do not pass these test requirements. (b) Exfiltration Test The pipeline shall be completely filled with water for its complete length or by sections as determined by the Engineer. If tested for its complete length, the maximum head at any point shall not exceed 25 feet unless otherwise indicated. If tested in sections, the manholes in the test section shall be completely filled with water. After the pipeline has been filled and allowed to stand for 24 hours, the amount of exfiltration shall be calcu- lated. Any amount in excess of 200 gallons per inch of inside pipe diameter per mile per day shall be cause for rejection. (c) Infiltration Test When the pipe placed in easements is completed, the upper portion of the ditch backfill shall be removed to a depth of not less than 18 inches below the finished surface and width equal to the original trench width. The trench shall then be flooded with water until It is completely saturated and water stands in the ditch a minimum of 12 inches deep. In cases of steep terrain, earthen dikes shall be used to assure that water will stand over the trench. After it is apparent that the trench is completely saturated, the main shall then be inspected with closed- circuit television for infiltration. Any section of the main or any service stub that indicates excessive infiltration shall be cause for rejection. This procedure shall not be used for pipes installed in areas where the P.I. of the surrounding material is 20 or higher or where the backfill material has a P.I. of 20 or more. (d) Pipeline Settlement Test During the infiltration test or after the exfiltration test, the pipe will be TV inspected for possible settlement. When air testing has been used, water shall be flowed into the pipe to permit meaningful observations. Any pipe settlement which causes excessive ponding of water in the pipe shall be cause for rejection. (e) Low Pressure Air Test of Gravity Flow Wastewater Lines (1) General Wastewater lines in sizes for which the City has testing equipment may, at the discretion of the Engineer, be air tested between manholes. Backlllling to grade shall be completed before the test and all laterals and stubs shall be capped or plugged by the Contractor so as not to allow air losses which could cause an erroneous test result. Manholes are to be plugged so they are isolated from the pipe and cannot be included in the test. All plugs used to close the sewer for the air test must be capable of resisting the internal pressures and must be securely braced. Place all air testing equipment above ground and allow no one to enter a manhole or trench where a plugged sewer is under pressure. Release all pressure before the plugs are removed. The testing equipment used must include a pressure relief device designed to relieve pressure in the sewer under test at 10 psi or less and must allow continuous monitoring of the test pressures in order to avoid excessive pressure. Use care to avoid the flooding of the air inlet by infiltrated ground water. (Inject the alr at the upper plug If possible.) Use only qualified personnel to conduct the lest. (2) Ground Water - Since the presence of ground water will affect the test results, test holes shall be dug to the pipe zone at intervals of not more than 100 feet and the average height of ground water above the pipe (if any) shall be determined before starting the test. (3) Test Procedure The Engineer may, at any time, require a calibration check of the instrumentation used. Use a pressure gauge having minimum divisions of 0.10 psi and an accuracy of 0.0625 psi. (One ounce pe( square inch.) All air used shall pass through a single control panel. Clean the sewer to be tested and remove all debris where indicated. Wet the sewer prior to testing. The average back pressure of any groundwater shall be determined (0.433 psi) for each toot of average water depth (i4 any) above the sewer. Add air slowly to the section of sewer being tested until the internal air pressure is raised to 4.0 psig greater than the average back pressure of any ground water that may submerge the pipe. Page 33 0411786 510 After the internal test pressure is reached, allow at least 2 minutes for the air temperature to stabilize, adding only the amount of air required to maintain pressure. After the temperature stabilization period, disconnect the air supply. II� Determine and record the time in seconds that is required for the intemal air pressure to drop Ink 3.5 psig to 2.5 psig greater than the average back pressure of any ground water that may submerge the PiPe. Compare the time recorded with the time required as follows: Pipe Size (Inches) 6 8 10 12 15 18 21 24 Time (Minutes) 3 4 5' 6 7.5 9 10.5 12 Any drop in pressure, from 3.5 psig to 2.5 psig, in a time less than that required by the above table shall be cause for rejection. When the line tested includes more than one size pipe, the minimum time shall be that given for the largest size pipe included. When lines are air tested, manholes are to be tested separately by exfiltration or infiltration. (27) Pressure Pipe Hydrostatic Testing After the pipe has been installed and backtiiled and all service laterals. fire hydrants and other appurtenances In- stalled and connected, a leakage test, followed by a pressure test, will be conducted by the City. The City will furnish the pump and gauges for the tests. The Contractor will be present and shall furnish all necessary assistance for conducting the tests. The specified test pressures will be based on the elevation of the lowest point of the line or section under test. Before applying the specified test pressure, all air shall be expelled from the pipe. If permanent air vents are not located at all high points, the Contractor shall install corporation cocks at such points. (a) Pressure Test The entire project or each valved section shall be tested. at a pressure of 200 pit for a sufficient period (ap- proximately 10 minutes) to discover all leaking or defective materials. Repairs shat' be made by the Contractor to correct any leaking or defective materials. (b) Pressure Pipe Leakage Test A leakage test will follow the pressure test and be conducted on the entire project or each valved section. The leakage test shall be at 150 psi for at least 1 hour. (28) Service Charges for Testing No charge will be made to the Contractor for the City's test equipment, Inspection, etc., when the test results show that leakage is within the indicated allowable limits. For each test, either for leakage or for pressure, which fails to meet the indicated requirements, the City's flat charge of $50.00 for such tests will be charged to the Contractor and will be deducted from any funds due the Contractor. 510 - 04/17/86 Page 34 (1) Allowable Leakage Leakage shall be defined as the quantity of water that must be supplied into any test section of pipe to maintain the specified leakage test pressure (see above, "Pressure Pipe Leakage Test ") after the air in the pipeline has been expelled and the pipe has been filled with water. The allowable leakage shall com- ply with AWWA C -600 which defines the allowable leakage as: L _ SD P 133,200 where L = Leakage in gallons per hour S = Length of pipe In feet D = Diameter (inside) of pipe in inches P = Pressure In pounds per square inch If such testing discloses leakage in excess of this specified allowable, the Contractor, at nis expense, shall locate and correct all defects in the pipeline until the leakage Is within the indicated allowance. 1 1 1 1 1 1 1 1 1 1 i1 1 1 1 1 1� 1 1 1 (29) Sterilization of Potable Water Lines The Contractor shall protect all piping materials from contamination during storage, handling and installation. Prior to disinfection, the pipeline interior shall be clean, dry and unobstructed. All dirt, debris, gasket lubncant, etc., shall be washed from the line by swabbing with hypochlorite solution and/or flushing with clean water. The City, at its expense, will supply the test gauges and the concentrated disinfecting material and City personnel will supervise and direct the overall sterilization procedure. The Contractor, at his expense, shall provide all other equipment, supplies and the necessary labor to perform the sterilization under general supervision of the City. (a) Procedure and Dosage All valves shall be arranged to prevent the strong disinfecting dosage from flowing back into the existing.water supply piping. The new pipeline shall then be completely filled with disinfecting solution by feeding the concen- trated chlorine and approved water from the existing system uniformly into the new piping in such proportions that every part of the line has minimum concentration of 50 parts per million (50 ppm or 50 mg /liter) 'available chlorine. Unless otherwise indicated, all quantities called for herein refer to measurements by the testing procedures in the current edition of "Standard Methods ". The chlorine concentration of each step in the sterilization proce- dure shall be verified by chlorine residual determinations. This disinfecting solution shall be retained in the piping for at least 24 hours and all valves, hydrants, etc., shall be operated to disinfect all their parts. After this retention period, the water shall contain no less than 25 parts per million chlorine throughout the treated sec- tion of the pipeline. This heavily chlorinated water shall then be carefully flushed from the line until the chlorine concentration is no higher than the residual generally prevailing in the existing distribution system or approximately one part per million. Proper planning and appropriate preparations to handle. dilute and dispose of this strong chlorine solu- tion without causing injury or damage to the public, the water system or the environment must be approved by the City before flushing of the line may begin and the flushing shall be witnessed by an authorized represen- tative of the City. (b) Bacteriological Testing - After final flushing of the strong disinfecting solution, water samples from the line shall be tested for bac- teriological quality by the City and must be found free of coliform organisms before the pipeline may be placed in service. One test sample shall be drawn from the end of the main and additional samples collected at inter- vals of not more than 1000 feet along the pipeline. The Contractor, at his expense, shall install sufficient sampling taps al proper locations along the pipeline. Each sampling tap shall consist of a standard corporation cock installed in the line and extended with a copper tubing gooseneck assembly. After samples have been collected, the gooseneck assembly may be removed and retained for future use. Samples for bacteriological analysis shall be collected only from suitable sampling taps in sterile bottles treated with sodium thiosulfate. Samples shall not be drawn from hoses, fire hydrants, etc. The City, at its expense, will furnish the sterile sample bottles and may, at its discretion, collect the test samples with City personnel. If the initial disinfection fails to produce acceptable sample tests, the disinfection procedure shall be repealed (without extra compensation) until satisfactory test results have been obtained before the piping may be placed in service. (30) Cleanup and Restoration It shall be the Contractors responsibility to keep the construction site neat, clean and orderly at all times. Cleanup shall be vigorous and continuous to minimize traffic hazards or obstructions along the streets and to drive- ways. Trenching, backfill and cleanup shall be coordinated as directed by the City. The Engineer shall regulate the amount of open ditch and may halt additional trenching if cleanup is not adequate to allow for orderly traffic flow and access. Materials at the site shall be stored in a neat and orderly manner so as not to obstruct pedestrian or vehicular traffic. All damaged material shall be removed from the construction site immediately and disposed of in a proper manner. All surplus excavated materials become the property of the Contractor for disposal at his expense. After trenching, the Contractor shall immediately remove all excavated materials unsuitable for or in excess of, backfill requirements. Immediately following the pipe laying work as It progresses, the Contractor shall backfill, grade and compact all excavations as provided elsewhere and shall immediately clean up and remove all unused soil, waste and debris and restore al surfaces and improvements to a condition equal or superior to that before construction began and to Page 35 04/17/86 510 an appearance which complements the surroundings. The Contractor shall grade and dress the top 6 inches of earth surfaces with soil or other material similar and equal to the surrounding, fill and smooth any visible tracks or ruts, replace and re- establish all damaged or disturbed turf or other vegetation and otherwise make every effort to en- courage the retum of the entire surface and all improvements to a pleasant appearance and useful condition appro- priate and complementary to the surroundings and equal or similar to that before construction began. 510.5 Measurement I Pipe will be measured by the linear foot along the centerline of the pipe for the various sizes and classes of pipe in place, in accordance with these specifications, complete and accepted by the Engineer, including excavation and backfill, unless they are included in the bid as a pay item.
