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 ~afety of either person or property during CONTRACTOR'S performance hereunder. 2.13 PRELIMINARY APPROVAL.

Where the estimated quantities are shown for the various classes of work to be done and material £o b'e 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. ]: is understood ind 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. Wher~ payment is based on the unit price method, the CONTRACTOR agrees that he will n~ake no claim for damages, anticipated profits or otherwise on account of any differences which rnav be found between the quantities of work actually done, the material actually furnished ~nc~er this contract and the estimated quantities contemplated and confined in the proposal; ~provided, however, that in case the actual quantity of any maior item should become as much 'as 20~ morb 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 "Ma'jor I~em" shall be construed to be any individual bid item incurred in the proposal ~hat "has' a ~otal cost equal to or grea~er 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 ?:'i,.'the term? of this Agreement, as provided under "Extra Work.".. · '~"~ "5'.03 "PRICE OF WORK. 'In consideration of the furnishing of all the n'ecessary labor, 'eq~'ipment ~nd 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 i~:onformity 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 chis Agreement. G-9 5.04 PARTIAL PAYMENTS. On Or before the?10th day of each month, the CONTRACTOR shall prepare and submit to the ENGINEER for approval or modification a statement showing as completely as practicable the total value of the Work done by the CONTRACTOR up to and including the last day of the preceding month; said statement shall also include the value of all sound materials delivered on the site of the work that are to be fabricated into the work. The OWNER shall then pay the CONTRACTOR on or before the 15th day of the current month the total amount of the approved~statbment.,';~ less I0 per cent of the amount thereof, which 10 per cent shall be retained until final payment, and further less all previous payments and all further sums that may be retained by the OWNER under the terms of this Agreement. It is understood, however, that in case the whole work be near to completion and some unexpected and unusual delay occurs due to no fault or neglect on the part of the CONTRACTOR, the OWNER may-upon written recommendation of the ENGINEER-pay a reasonable and equitable portion of the retained percentage to the CONTRACTOR, or the CONTRACTOR at the OWNER'S option, may be relieved of the obligation to fu!!y complete the work and, thereupon, the CON- TRACTOR shall receive payment of the balance due him under the contract subject only to the conditions stated under "Final Payment." 5.05 USE OF COMPLETED PORTIONS. Tile OWNER shall have tile 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 tile 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 and will add thereto such items as the CONTRACTOR has failed to include. The "substantial completion" of tile 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 Document~. 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 tile OWNER shall inspect the work and within said time, if the work be found to be completed or substantially completed in accordance with tile Contract Documents, tile ENGINEER shall issue to the OWNER and the CONTRACTOR his Certificate of Completion, and thereupon it shall be the duty of the OWNER.within ten (10) days to issue a Certificate of Acceptance of the work to the CONTRACTOR or to advise the CONTRAC- TOR in writing of the reason for non-acceptance. 5.07 FINAL 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 of 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 of the obligation for fulfillment of any warranty which may be required. 5.08 PAYMENTS WITHHELD. The OWNER may. on account of subsequently discovered ~,vidence, 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 e) -, (a) Defective work not remedied. (b) Claims fi]ed or reasonable evidence indicating probable filing of claims. (c) Failure of the CO~FRACTOR to make payments properly to sub- contractors or for material or labor. . (d) Damage to another contractor. (e) Reasonable doubt that the work can be completed for the unpaid balance of ~e contract amount. (f) Reasonable indication that the work will not be completed within the contract time. When the above grounds are removed or the CONTRACTOR provides a Surety Bond satisfactory to the OWNER, which will protect the OWNER in the amount withheld, payment shall be made for amounts withheld because of them. 5.09 DELAYED PAYMENTS. Should the OWNER fail to make payment to the CONTRAC- TOR of the sum named in any partial or final statement, when payment is due, then the OWNER shall pay to the CONTRACTOR, in addition to the sum shown as due by such .statement, interest thereon at the rate 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 ir, 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 th~ Change Order and the CONTRACTOR may make claim against the OWNER for Extra Work involved therein, as herein- after provided. 6.02 MINOR CHANGES: The ENGINEER may authorize minor changes in the work not inconsistent with the overall intent of the Contract Documents and not involving an increaze in Contract Price. If the CONTP,.A~R 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 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: Method (A)--By agreed unit prices; or Method (B)'-By agreed lump sum; or Method (C)--I/ neitl~r Method (A) nor Method (B) be ~greed 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 mad paid 'for under Method (C), then the pro- visions of this paragraph shall apply and the "actual field cost" is hereby dell-ed to include the cost to the CONTRACTOR of all workmen, such az 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 tr~n-,portation charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating expenses, ~o 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 az may be required by any law or ordinance, or directed by the OWNER, or by them agreed to. The ENGINEER may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made available to the ENGINEER. The ENGINEER or OWNER may also specify in writing, before the work commences, -the method of doing the work and the .type and kind of machinery and equip- mznt to be used; oUherwise these matters shall be determined by the CONTRACTOR. Unless otherwise ~greed upon, the prices for the use of machinery and equipment shall he determined by using 100 per cent, unless otherwise specified, of the latest schedule of Equipment Ownership Expense adopted by the .4z.sociated 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" az 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 shah make written request to the ENGINEER for written order authorizing such Extra Work. Should a difference of opinion arise az to what does or does not constitute Extra Work, or az to the payment therefor, and the ENGINEER iniists upon its performance, 'the CONTRACTOR shall proceed with the work ~fter making written request for written order and shall keep an accurate account of the "actual field cost" thereof, az provided under Method (C). The CONTRACTOR will thereby presage the right to submit the matter of payment to arbitration, az hereinbelow provided. 6.04 TIME OF FILING CLAIMS. It is further agreed by both parties hereto that questions of dispute or adjustment presented by the CONTRACTOR shall be ia writing ~-d filed with the ENGINEER within thirty (30) da:~ ~fter the ENGINEER has given ~ny directions, order or instruction to which the CONTRACTOR desires to take exception.

The parties may agree upon one arbiter, otherwize, there shall be three, one named in writing by each party, ~nd the third chosen G-12 ® ,, ,,- ,-.. ---- ,,,, by the two arbiter~ so selected; or if the arbiter~ fail to select a third wRhin 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.

The arbiters shall fix their own compensation, unless otherwise provided by agreement, and shall assess the cost and charges of the axbkration, 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 O~A~'ER, or the ENGINEER, or if the CONTRACTOR fails to comply with the orders of the ENGINEER, when such orders are consistent ,with the Contract Documents, then, and in that case, where performance and payment bonds exist, the Sureties on these bonds shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the CONTRACTOR. After receiving said notice of abandonment the CONTRACTOR shall not remove from the work any machinery, equipment, tools, materials or Supl~lies then on the job, but the same, together with any materials and equipment unde~r contract fo~ the work, may be held for use on the work by the OWNER or the Surety on the perfpr~nce bond, or another contractor in completion of the work; and the CONTRACTOR shall not ~ec~ive 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 thatithe use of such equipment and materials will ultimately reduce the cost to complete the work an~be reflect.ed im 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 ~z said OWNER may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materiah and supplies to said CONTRACTOR, and expense so charged shall be deducted and paid by the OWNER out of such moneys as may be due, or that may thereafter at any time become due to the CONTRAC- TOR under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the CONTRACTOR, then said CONTRACTOR shall receive the difference. In c~ze 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 '/.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 credked 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 and/or his Surety, or the OWNER as the case may be, shall pay the balance due as reflected by said st. atement, 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 ~ver 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 O~,'NER 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 09,,~ER to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the OV~ER ma)' sell suc}', 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 ot private sale, with or without notice, as the OWNER ma)' elect. The OV,.~ER shall release any machinery, equipment, tools,'-materials, or supplies, which remain on the work, and belong to persons other than the CONTRACTOR or his Surety, to their proper owners. The books on all operations provided herein shall be open to the CONTRACTOR and his Surety. 7.02 ABANDONMENT BY OWNER. In case the OV~'~ER 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 ~'alue of ali work actually completed by said CONTRACTOR (at the prices state~[ in '~he attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the CONTRACTOR to carry the whole work to completion and which cannot be utilized. The ENGINEER shall then make a final statement of the balance due the CONTRACTOR by deducting from the above estimate all previous payments by the O%,~ER and all other sums that may be retained by the O~,VNER under the terms of this Aareement 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.

INSTALLATION OF CABLE General The cables shall be installed in the conduit. The conduit must be continuous, reasonably dry, completely free of debris, and without any sharp projections, edges, or short bends. The conductors shall be installed in such manner and by such methods as to insure against harmful stretching of the conductor or damage to the insulation and shall conform to the recommendations of the cable manufacturer. The Contractor shall furnish, at the request of the Engineer, at least two copies of the manufacturer's recommendations, including methods of attaching pulling tension per conductor size and per radius of conduit bend, and the type of lubricant to be used. All cables in a given conduit run shall be pulled at the same time and the conductors shall be assembled to form one loop in such a manner that the pulling tension is distributed to all the cables. Long, hard pulls will necessitate the use of pulling eyes. For short runs, the cables may be gripped directly by the conductors by forming them into a loop to which the pull wire or rope can be attached. The insulation on each conductor shall be removed before the loop is formed. The method used will depend on the anticipated maximum pulling tension in each case. In many instances, existing conduits which contain signal cable are to be used for the installation of new cables. In such locations, the existing cable(s) may be used to pull in the new cables. Should the Contractor desire to install new cables without removing the existing cables, the new installation shall be done in such a way as to prevent damage to the existing and/or new cables. In the event of damage, the Contractor shall bear the responsibility of replacement of defective cables. 48 11.1.4 11.1.5 11.2 11.2.1 11.3 11.3.1 11.3.2 The manufacturer's recommended maximum pulling tensions shall not be exceeded under any circumstances. If so required by the Engineer, the Contractor shall insert a dynamometer in the pull wire as the cables are being pulled into the conduit to demonstrate that the maximum tensions are not being exceeded. The cable shall be fed freely off the reel into the conduit without making a reverse curve. At the pulling end, the pull wire and or other suitable devices shall be used as required to reduce any hazards to the cable during installation. The cables shall be adequately lubricated to reduce friction and further minimize possible damage. Such lubricants shall not be the grease or oil type used on lead sheathed cables but shall be one of several commercially available wire pulling compounds that are suitable for these kinds of cables. They shall consist of soap, talc, mica, or similar materials and shall be designed to have no deleterious effect on the cables being used. The cables shall be neatly trained to their destinations in manholes, cabinets, pole bases, pullboxes, and all other terminations. The cable manufacturer's recommended values for the minimum bending radii to which cables may be bent for permanent training during installation shall be adhered to. These limits do not apply to conduit bends, sheaves or other curved surfaces around which these cables may be pulled under tension while being installed. Larger radius bends are required for such conditions.
