Likewise, the CONTRACTOR shall be solely responsible for the safety of himself, his employ- ecs 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, ~s a result of his operations hereunder. Engineer- lng construction drawings and specifications as well as any additional information concerning the work to be performed pas~ing from or through the ENGINEER shall not be interpreted ~s requiring or allowing CONTRACTOR to deviate from the plans and specifications, the intent of such drawings, specifications and any other such instructions being to define with particularity the agreement of the parties as to the work the CONTRACTOR is to perform. CONTRACTOR shall be fully and completely liable, at his own expense, for design, construction, installation and use, or non-use, of all items and methods incident to performance of the contract, and for all loss, damage or injury incident thereto, either to person or property, including, without limitation, the adequacy of all temporary supports, shoring, bracing, scaffolding, machinery or equipment, safety precau- tions or devices, and similar items or devices used by him during construction. Any review of work in process, or any visit or observation during ~:onstruction, or any clarification of plans and specifications, by the ENGINEER, or any agent, employee, or represen- tative of either of them, whether through personal observation on the project site or by means of approval of shop drawings for temporary construction or construction processes, or by other means or method, is agreed by the CONTRACTOR to be for the purpose of observing the extent and nature of work completed or being performed, as measured against the drawings and specifications constituting the contract, or for the purpose of enabling CONTRACTOR to more fully understand the plans and specifications so that the completed construction work will conform thereto, and shall in no way relieve the CONTRACTOR from full and complete responsibility for the proper performance of his work on the project, including but without limitation the propriety 'of means and methods of the CONTRACTOR in performing said contract, and the adequacy of any designs, plans or other facilities for accomplishing such performance. Deviation by the CONTRACTOR from plans and specifications that may have been in evidence during any such visitation or observation by the ENGINEER, or any of his representatives, whether called to the CONTRAC- TOR'S attention or not shall in no way relieve CONTRACTOR from his responsibility to complete all work in accordance with said plans and specifications. 2.08 CONTRACTOR'S UNDERSTANDING. It is understood and agreed that the CON- TRACTOR has, by careful examination, satisfied himself as to the nature and location of the work, the conformation of the ground, the character, quality and quantity of the materials to be encoun- tered, the character of equipment and facilities needed preliminary to and during the prosecution of the work, the general and local conditions, and all other matters which can ~.n any way affect the work under this contract.

The CONTRACTOR shall submit to the ENGINEER, with such promptness as to cause no delay in his own work or in that of any other Contractor, four checked copies, unless otherwise specified, of all shop and/or setting drawings and schedules required for the work of the various trades, and the ENGINEER shall pass upon them with reasonable prompt- ness, making desired corrections. The CONTRACTOR shall make any corrections required by the ENGINEER, file with him two corrected copies and furnish such other copies as may be needed. The ENGINEER'S approval of such drawings or schedules shall not relieve the CONTRACTOR from responsibility for deviations from drawings or specifications, unless he has in writing called the ENGINEER'S attention to such deviations at the time of submission, nor shall it relieve him from responsibility for 'errors of any sort in shop drawings or schedules. It shall be the CONTRAC- TOR'S responsibility to fully and completely review all shop drawings to ascertain their effect on his ability to perform the required contract work in accordance with the plans and specifications and within the contract time. Such review by the ENGINEER shall be for the sole purpose of determining the sufficiency of said drawings or schedules to result in finished improvements in conformity with the plans and specifications, and shall not relieve the CONTRACTOR of his duty as an independent contractor as previously set forth, it being expressly understood and agreed that the ENGINEER does not assume any duty to pass upon the propriety or adequacy of such drawings or schedules, or any means or methods reflected thereby, in relation to the safety of either person or property during CONTRACTOR'S performance hereunder. 2.13 PRELIMINARY APPROVAL. The ENGINEER shall not have the power to waive the obligations of this contract for the furnishing by the CONTRACTOR of good material, and of his performing good work as herein described, and in full accordance with the plans and specifica- tions.

Any questioned work may be ordered taken up or removed for re-examination, by the ENGINEER, prior to final acceptance, and if found not in accordance with the specifications for said work, all expense of removing, re-examination and replacement shall be borne by the CONTRACTOR, otherwise the expense thus incurred shall be allowed as EXTRA WORK, and shall be paid for by the OWNER; provided that, where inspection or approval is specifically required by the specifications prior to performance of certain w'~rk, should the CONTRACTOR proceed with such work without requesting prior inspection or al~,roval he shall bear all expense of taking up, removing, and replacing this work if so directed by the ENGINEER. 2.14 DEFECTS AND THEIR REMEDIES. It is further agreed that if the work or any part thereof, or any material brought on the site of the work for use in the work or selected for the same, shall be deemed by the ENGINEER as unsuitable or not in conformity with the speci- fications, the CONTRACTOR shall, after receipt of written notice thereof from the ENGINEER, forthwith remove such material and rebuild or otherwise remedy such work so that it shall be in full accordance with this contract. 2.15 CHANGES AND ALTERATIONS. The CONTRACTOR further agrees that the OWNER may make such changes and alterations as the OWNER may see fit, in the line, grade, form, dimensions, plans or materials for the work herein contemplated, or any part thereof, either before or after the beginning of the construction, without affecting the validity of this contract and the accompanying Performance and Payment Bonds. If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the basis for a claim for damages, or anticipated profits on the work that may be dispensed with, except as provided for unit price items under Section 5 "Meuurement and Pay- ment." If the amount of work is increased, and the work can fairly be classified under the speci- fications, such increase shall be paid for according to the quantity actually done and at the unit price, if any, established for such work under this contract, except as provided for unit price items under Section 5 "Measurement and Payment;" otherwise, such additional work shall be paid for as provided under Extra Work. In case the OWNER shall make such changes or alterations as shall make useless any work already done or material already furnished or used in said work, then the OWNER shall recompense the CONTRACTOR for any material or labor so used, and for any actual loss occasioned by such change, due to actual expenses incurred in preparation for the work as originally planned. 3.

No extra or customary measurements of any kind will be allowed, but the actual measured and/or computed length, area, solid contents, number and weight only shall be considered, unless otherwise specifically provided. " 5.02 ESTIMATED QUANTITIES. This agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. ]t is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and the material furnished. Where payment is based on the unit 9rice method, the CONTRACTOR agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which tnav be found between the quantities of work actually done, the material actually furnished ~nc~er this contract and the estimated quantities contemplated and contained in the proposal~ ~provided, however, that in case the actual quantity of any major item should become as much 'as 202 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 "Major Item" shall be construed to be any individual bid item incurred in the proposal that ~has a ~otal 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 ~b~ the terms of this Agreement, as provided under "Extra Work." '"'" ':5'.03 i'PRICE OF WORK. 'In consideration of the furnishing of all the necessary labor, equipment and material,', and the completion of all work by the CONTRACTOR, and on the completion of all work and of the delivery of all material embraced in this Contract in full 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 5.04 PARTIAL PAYMENTS. On Or before the 10th day of each month, the CONTRACTOR shall prepare and submit to the ENGINEER for approval or modification a statement showing as completely as practicable the total value of the work done by the CONTRACTOR up to and including the last day of the preceding month; said statement shall also include the value of all sound materials delivered on the site of the work that are to be fabricated into the work. The OWNER shall then pay the CONTRACTOR on or before the 15th day of the current month the total amount of the approved statement, less I0 per cent of the amount thereof, which 10 per cent shall be retaiaed 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. The OWNER shall have the right to take possession of and use any completed or partially completed portions of the work, notwithstanding the time for completing the entire work or such portions may not have expired but such taking possession and use shall not be deemed an acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost of or delays the work, the CONTRACTOR shall be entitled to such extra compensation, or extension of time, or both, as the ENGINEER may determine. The CONTRACTOR shall notify the ENGINEER when, in the CONTRACTOR'S opinion, the contract is "substantially completed" and when so notifying the ENGINEER, the CONTRAC- TOR shall furnish to the ENGINEER in writing a detailed list of unfinished work. Tile 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 the structure or facility shall not excuse the CONTRACTOR from performing all of the work undertaken, whether of a minor or major nature, and thereby completing the structure or facility in accordance with the Contract Documents. 5.06 FINAL COMPLETION AND ACCEPTANCE. Within ten (10) days after the CON- TRACTOR has given the ENGINEER written notice that the work has been completed, or substantially completed, the ENGINEER and the OWNER shall inspect the work and within said time, if the work be found to be completed or substantially completed in accordance with the Contract Documents, the ENGINEER shall issue to the OWNER and tile 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 evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of: (a) Defective work not remedied. (b) Claims filed or reasonable evidence indicating probable filing of claims. (c) Failure of the CONTRACTOR to make payments properly to sub- contractors or for material or labor. . (d) Damage to another contractor. (e) Reasonable doubt that the work can be completed for the unpaid balance of the contract amount. (f) Reasonable indication that the work will not be completed within the contract time. When the above grounds are removed or the CONTRACTOR provides a Surety Bond satisfactory to the OWNER, which will protect the OWNER in the amount withheld, payment shall be made for amounts withheld because of them. 5.09 DELAYED PAYMENTS, Should the OWNER fail to make payment to the CONTRAC- TOR of the sum named in any partial or final statement, when payment is due, then the OWNER shall pay to the CONTRACTOR, in addition to the sum shown as due by such statement, interest thereon at the rate 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 ss set forth in the Change Order and the CONTRACTOR may make claim against the OWNER for Extra Work involved therein, as herein- after provided. 6.02 MINOR CHANGES: The ENGINEER may authorize minor changes in the work not inconsistent with the overall intent of the Contract Documents and not involving an increase in Contract Price. If the CONTRACTOR believes that any minor change or alteration authorized by the ENGINEER involves Extra Work and entitles him to an increase in the Contract Price, the CONTRACTOR shall make written request to the ENGINEER for a written Field Order. In such case, the CONTRACTOR by 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 oi' 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)--If neither Method (A) nor Method (B) be ~eed upon before the Extra Work is commenced, then the CONTRACTOR shall be paid the "actual field cost" of the work, plus fifteen (15) percent. In the event said EXtra Work be performed and paid 'for under Method (C), then the pro- visions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost to the CONTRACTOR of all workmen, such as foreman, timekeepers, mechanics and laborers, and materials, supplies, teams, trucks, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges nece~.~rily incurred, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, including Social Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of premiums on Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property Damage and Workmen's Compensation, and all other insurance as may be required by any law or ordinance, or directed by the OWNER, or by them agreed to. The ENGINEER may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made available to the ENGINEER. The ENGINEER or OWNER may also specify in writing, before the work commences, .the method of doing the work and the type and kind of machinery and equip- mznt 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 incorporated in the Written Extra Work Order. The fifteen (15%) per cent of the "actual field cost" to be paid the CONTRAC- TOR shall cover and compensate him for his profit, overhead, general superintendence and field office expense, and all other elements of cost and expense not embraced within the "actual field cost" as herein defined, save that where the CONTRACTOR'S Camp or Field Office must be maintained primarily on account of such Extra Work; then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for Extra Work of any kind will be allowed unless ordered in writing by the ENGINEER. In case any orders or instructions, either oral or written, appear to the CONTRAC- TOR to involve Extra Work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the ENGINEER for written order authorizing such Extra Work. Should a difference of opinion arise as to what does or does not constitute Extra Work, or as to the payment therefor, and the ENGINEER insists upon its performance, 'the CONTRACTOR shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as provided under Method (C). The CONTRACTOR will thereby preserve the right to submit the matter of payment to arbitration, as hereinbelow provided. 6.04 TIME OF FILING CLAIMS. It is further agreed by both parties hereto that ali 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 -xceptions 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 where noted otherwise in the Contract Documents. 6.05 ARBITRATION. All questions of dispute under-this Agreement shall be submitted to arbitration at the request of either party to the dispute. The parties may agree upon one arbiter, otherwise, there shall be three, one named in writing by each party, and the third chosen G-12 ® ,, ,.- ,-.- ,,,, ,*', by the two arbiters ~o 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 Iocsted, 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 parts proceedings. The arbiters shall act with promptnesz. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any question submitted to arbitration under this contract shall be a condition precedent to any right of legal action. The 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 written notification from the OV~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 supplies then on the job, but the same, together with any materials and equipment under contract for the work, may be held for use on the work by the OWNER or the Surety on the performance bond, or another contractor in completion of the work; and the CONTRACTOR shall not receive any rental or credit therefor (except when used in connection with Extra Work, where credit shall be allowed as provided for under Section 6, Extra Work and Claims), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. Where there is no performance bond provided or in ease t~e Surety should fail to commence compliance with the notice for completion hereinbefore provided for, within ten (10) days after service of such notice, then the OWNER may provide for completion of the work in either of the following elective manners: 7.01.1 The OWNER may thereupon employ such force of men and use such machinery, equipment, tools, materials and supplies as said OWNER may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said CONTRACTOR, and expense so charged shall be deducted and paid by the OWNER out of such moneys az may be due, or that may thereafter at any time become due to the CONTRAC- TOR under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the CONTRACTOR, then said CONTRACTOR shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said CONTRACTOR, then the CONTRACTOR and/or his Surety shall pay the amount of such excesz to the OWNER; or 7.01.2 The OWNER under sealed bids, after five (5) days notice published one or more times in a newspaper having general circulation in the county of the location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case any increase in cost to the OWNER under the new contract as compared to what would have been the cost under this contract, such increase shall be charged to the CONTRACTOR and the Surety shall be and remain bound therefor. However, should the cost to complete any such new contract prove to be less than what would have been the cost to complete under this contract, the CONTRACTOR and/or his Surety shall be credited therewith. G-13 ~ '~ ~"' "~°' '~ .... When the work shall have been substantially completed the CONTRACTOR and his Surety shall be so notified and Certificates of Completion and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the contract accounts, certified to by the ENGINEER as being correct, shall then be prepared and delivered to the CONTRACTOR and his Surety, whereupon the CONTRACTOR 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 Zor 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 OV~,~ER 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 ot private sale, with or without notice, as the OWNER may elect. The O~,.~ER shall release any machinery, equipment, tools,' materials, or supplies, which remain on the ~'ork, and belong to persons other than the CONTRACTOR or his Surety, to their proper owners. The books on all operations provided herein shall be open to the CONTRACTOR and his Surety. 7.02 ABANDONMENT BY OWNER. In case the OWNER shall fail to comply with the terms of this contract, and should fail or refuse to comply with said terms within ten (10) days after written notification 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 ~he attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the CONTRACTOR to carry the whole work to completion and which cannot be utilized. The ENGINEER shall then make a final statement of the balance due the CONTRACTOR by deducting from the above estimate all previous payments by the OWNER and all other sums that may be retained by the OWNER under the terms of this Aereement and shall eertifv 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.

PENALTY FOR DEFICIENT CONCRETE STRENGTH. It is the intent of this specification that all concrete construction covered by this specification be constructed in strict conformity with the plans and these specifications. Where any work is found to be constructed of concrete with strength values of less than the specified minimum strength, the following rules relative to adjustment of payment for acceptable work and to replacement of faulty work shall govern. (a) If the results of the compressive cylinder tests indicate a deficient strength and the Contractor does not elect to drill cores for a final compressive strength test, adjustments will be made on the basis for the compressive strength value for the particular area concerned as determined from the cylinders cast for compressive tests as herinafter specified. (b) If the Contractor elects to take cores for a final compressive strength test, the compressive strength value as determined by the core tests shall be conclusive. If the results of the core tests indicate a deficient strength, adjustment will be made on the basis of the compressive strength value as determined by the core tests. Sec. 07500 16 (c) If the concrete compressive strength is less than the minimum required strength, the amount of penalty per square yard of concrete having a deficient strength shall be in accordance with the following table: PERCENT DEFICIENT AMOUNT OF PENALTY O% TO 5% Greater than 5--not more than 10% Greater than 10-not more than 15% $2.00/S.Y. $5.00/s. Y. NO Payment* The amount of Penalty shall be deducted from payment due or to become due to the Contractor; such penalty deducted is to defray the cost of extra maintenance. *If, in the judgment of the Engineer, the area of deficiency should not be removed and replaced, there will be no payment for the area retained. (d) Ail concrete having a strength more than 15 percent deficient shall be removed and replaced with concrete meeting the requirements of these specifications at the entire cost and expense of the Contractor. (e) The area of concrete concerned in the adjustment or removal shall be the designated area represented by the com- pressive strength values determined as hereinabove specified. Measurement for adjustment or removal shall be made to points equidistant between acceptable and unacceptable test points (points at which a compressive strength value was determined). Article 360.4 PROPORTIONING CONCRETE,Subarticle (5) Mix Design, is hereby deleted in its entirety and replaced by the following: MIX DESIGN. It is the intent of this specification to develop and use the most economical mix design possible which will fulfill all requirements of this specification when using acceptable materials as furnished by the Contractor. Prior to the beginning of concrete placements, and thereafter before any change in source or characteristics of any of the ingredients except mineral filler, mix design tests shall be performed using the cement and aggregates proposed for use. The Contractor will be required to furnish the Engineer with all concrete batch designs necessary to produce the required strength as specified in the contract and specifications. All designs must be submitted by the Contractor and approved by the Engineer before the placing of concrete will be permitted. At any time when any change in source or charac- teristics of any of the ingredients except mineral filler is expected, results of the mix design tests required above shall be submitted to the Engineer in order that he may determine whether a change in the approved mix design is required. Sec. 07500 17 Concrete mixes will be designed and made in sufficient number to represent a wide range of water-cement ratios; these mixes shall comply with the requirements therein prescribed for workability. The water-cement ratio is defined as the total U.S. gallons of water (weight 8.33 pounds) including the moisture content of all aggregates per sack of cement (weight 94 pounds net). From the concrete of each mix design test beams will be made, cured and tested to determine the flexural strength of the concrete at 7 days. From these preliminary tests, the water-cement ratio required to produce concrete of the specified strength will be selected. Prior to placing of any concrete, the Contractor, will be required to furnish and operate the specified mixer approved for use on the project and shall produce batches of the size to be used in the concreting operations. From these batches, pilot beams will be made and tested in order to determine if the designs submitted comply with the strength requirements. No additional compensation will be paid for equipment, materials, and labor for making these preliminary test specimans. Such tests may be waived upon submission of approved independent laboratory design or previous satisfactory tests obtained from materials of the same sources. After the mix proportions and water-cement ratio required to produce concrete of the specified strength have been determined and after the Engineer has approved the mix design, placing of concrete may be started. Concurrence on the part of the Engineer in any proposed mixing or placing methods or approval of any proposed mix design shall not relieve the Contractor of the responsibility of furnishing concrete in place conforming to the requirements of these specifications. Changes in the water-cement ratio and the mix design shall be made when the strength of the concrete departs from the specified minimum strength as indicated by the strength values obtained from tests of specimens made from concrete being placed. CONCRETE DESIGN FOR INTERSECTIONS. When the paving and finishing of street intersections and left-turn lanes are accomplished by hand methods, the concrete used shall conform to the following special requirements: (No fly ash admixture will be allowed in the mix design.) LOCATION MINIMUM CEMENT CONTENT F~X. SLUMP Major Thoroughfares Secondary Thoroughfares Residential Streets 6 sacks per cubic yard 5.75 sacks per cubic yard 5 sacks per cubic yard 4 inches 4 inches 4 inches These special conditions will not be required when the intersection or left-turn lane will be placed and finished by Sec. 07500 18 mechanical methods. If the plans or special provisions indicate that traffic will be routed over the new concrete surface prior to the normal 7-day waiting period, the use of high-early strength portland cement will be required. When high-early strength portland cement is used, traffic will not be allowed on the surface for a minimum period of 72 hours after placing of the concrete. Article 360.4 PROPORTIONING CONCRETE, Subarticle (6) Test Specimens, is hereby deleted in its entirety and replaced by the following: TEST SPECIMENS AND QUALITY CONTROL.' During the progress of the work the Engineer will cast test cylinders and beams for testing to maintain a check on the compressive and flexural strengths of the concrete actually being placed. Concrete failing to meet the specifications for materials, proportions, construction methods, strength or dimensions may be required to be removed and replaced with concrete meeting the specified requirements. Not less than 3 test cylinders for a compressive strength value and 2 test beams for a flexural strength value will be taken from the concrete for each 450 square yards or less of concrete pavement placed each day. A compressive or flexural strength value shall be the average of the strengths of the three cylinders or two beams as the case may be. Additional cylinders or beams may be made by the Engineers as required by concrete placing conditions, or for adequately determining the strength of the concrete where the early use of the base or pavement is dependent upon the concrete strength tests. No extra compensation will be paid the contractor for materials and labor involved in fulfilling these requirements. Beam boxes shall be furnished by the Contractor. Beam boxes shall be as specified or as directed by the Engineer. Furnishing of beam boxes will not be paid for as a separate contract pay item, and the costs thereof shall be included in such pay items as are provided in the proposal and contract. Beam boxes shall be maintained by the Contractor without cost to the Owner. The test beams shall be tested at the age of 7 days in order to-determine the flexural strength. Should the average 7 day flexural strength value, as determined by the average of the last 10 flexural strength values obtained from test of beams made from concrete of the same water-cement ratio, fail to meet the strength requirement, the Contractor shall modify the mix design to obtain additional strength in order to fulfill the requirements for compressive strength at 28 days. The test cylinders from those specific areas where individual test beams were below required strength shall be tested at the age of 28 days in order to determine the compressive strength of these areas. Should any set of test cylinders Sec. 07500 19 representing a given area where an individual test beam has failed to meet strength requirements, that area shall be considered to be composed of concrete having deficient strength. The Engineer, at his option, may reject as non- represenatative any individual flexural strength value in each group of ten where strengths more than 10 percent above or below the average for the group are indicated, and compute the average flexural strength on the basis of the remaining values.

Exact location, depth and size must be verified by the contractor in the field. Additional compensation will not be allowed if damage to the utilities results because of minor discrepancies between locations shown on the drawings and actual field locations. Relocation of utilities in place shall be done whether or not such work is specifically shown on the drawings. 2. Any existing utilities that may be shown on the drawings or the location of which is made known to the contractor prior to excavation shall be protected from damage during the excavation and backfilling of trenches and, -if damaged, shall be repaired by the contractor at his expense. 3. Any existing utility that is not Shown on the drawings or the location of which are not known to the contractor in sufficient time to avoid damage, if inadverttently damaged during excavation, shall be immediately repaired by the contractor due to the existence of utilities that are not shown on the drawings or the location of which is not known to the contractor at the time of bidding. Any existing utility lines and services shall be maintained at all times, except for such short periods of time as may be necessary to actually make connections to new work to the existing system. When it is necessary to temporarily interrupt service for the above purpose, such shall be done only at such date and time as may. be established in advance by the Engineer. Thoses lines shown on the drawings to be abandoned or removed shall not be abandoned or removed until after it has been determined that they are no longer required for service and until such action has been approved by the Owner and the Engineer. Sec. 07500 47 F. LINES, GRADES, STAKES AND TEMPLATES Ge The Contractor shall, at his own expense, furnish all stakes, templates, patterns, platforms and labor, including a person qualified to lay out all of the work. The Engineer will furnish, upon request from the Contractor, limit marks and bench marks reasonably necessary for the execution of the work. It shall be the Contractor's responsibility to protect these limit marks and bench marks set by the Engineer. Should the marks become destroyed or damaged, the cost of their replacement will be at the Contractor's expense. The Engineer may furnish a representative to check alignment and grade, after it has been laid out ready for construction; however, this will in no way lessen the responsibility of the Contractor to see that grade and alignment are correct at all times. Se The lines and grade of the sewer, as well location of manholes, wyes, and all appurtenances, will be as shown on the plans directed by the Engineer. as the other or as The Engineer reserves the right to indicate which sewer lines will receive priority in construction. The work will, in general, be from the lower end of the system toward the upper end of the system. The Contractor shall give the Engineer a minimum of forty-eight (48) hours notice for any engineering or inspection necessary to continue or complete the work. No deviation shall be made from the required line or grade without written approval from the Engineer.

The excavation of the trench shall not advance more than 200 feet ahead of the completed pipe work except where, in the opinion of the Engineer, it is necessary to drain wet ground, or for other reasons as approved by the Engineer. Ail excavations shall be made in accordance with the provisions shown on Sheet 54 of 56 of the Drawings entitled, "Trench & Slope Excavation Detials." Trench Sec. 07500 48 ® bottoms shall not be less than 12 inches wider nor more than 16 inches wider than the outside diameter of the pipe laid therein, and shall be excavated true to line, so that clear space of not less than 6 inches nor more than 8 inches in width is provided on each side of the pipe. The bottom of trenches shall be accurately graded to provide uniform bearing and support for each section of pipe or undisturbed soil at every point along its entire length, except for positions of the pipe sections where it is necessary to excavate for bell holes. Bell holes shall be excavated only to an extent sufficient to permit accurate work in the making of the joints and to insure that the pipe, for a maximum of its length, will rest upon the prepared bottom of the trench. The bottom of all trenches shall be rounded so that at least one-fourth (1/4) of the circumference of the pipe rests firmly on undisturbed soil. If the Contractor should, by error, excavate below the proper elevation for the bed of the pipe or should he desire to substitute an approved granular backfill, properly tamped, for supporting the pipe to the same extent as the shape trench bottom, then the Contractor must bring the trench bottom to the proper grade by refilling, at the Contractor's expense, with an approved granular backfill. This backfill material shall be sand or fine gravel that does not contain large rocks or other deleterious materials and should be placed so that it is at least 2 inches deep below the bottom and so that the lower one-third (1/3) of the pipe is uniformly supported on undisturbed soil. Ail excavation shall be placed on one side of the trench in conformance with the provisions of Sheet 100 of 102 of the Drawings, entitled "Trench & Slope Excavation Details," unless permission is given by the Engineer to place it on both sides. Excavated materials shall be placed so as not to endanger the work and workmen, and so that free access may be had at all times to all parts of the trench. All shade trees, shrubs, etc., along the line of construction shall reasonably protected, and tunneled if necessary unless specific directions are given to remove them. The Contractor shall provide, without additional compensaion, suitable temporary channels for the water that may flow along or across the site of the work. Any water pumped from the trenches, or other excavations, must be disposed of in a manner satisfactory to the Engineer. Sec. 07500 49 H. BRACING AND SHORING me The Contractor shall, furnish, put in place, and maintain, such sheeting, bracing, shoring, etc. (in accordance with the provisions of Sheet 54 of 56 of the Drawings, entitled "Trench & Slope Excavation Details") as may be required to support the sides of the excavation and to prevent any movement which can in any way damage adjacent pavement or other structures, damage or delay the work or construction, or endanger life and health. Care shall be taken to prevent voids outside the sheeting, but, if voids are formed, they shall be immediately filled and rammed to the satisfaction of the Engineer. For the purpose of preventing injury to persons, corporations or property, whether public or private, (where the liability for damage on account of which is to be assumed entirely and solely by the Contractor under this contract) he may also leave in place, to be embedded in the backfill of the trench any and all sheeting, bracing, etc., in addition to that ordered in writing by the Engineer to be left in place, except that no sheeting and bracing which is within 4 feet of the surface of the street may be left in place in the trench without written permission of the Engineer. Ail sheeting and bracing which may not be left in place under the foregoing conditions must be removed upon completion of backfilling the trench. Ail voids left by the withdrawal of sheeting shall be immediately refilled and compacted by ramming or water, or otherwise, as may be directed. The right of the Engineer to order sheeting and bracing left in place shall not be construed as creating an obligation on his part to issue such orders; and his failure to exercise his right to do so shall not relieve the Contractor from liability or damages to persons or property, occurring from or upon the work of constructing the sewer occasioned by negligence or otherwise, growing out of the failure of the Contractor to leave in place in the trench sufficient sheeting and bracing to prevent any caving or moving of the ground adjacent to the banks of the trench. DEWATERING The Contractor shall at all times during construction, provide and maintain ample means and devices with which to promptly remove and properly dispose of all water entering the sewer trenches or excavations, and keep said excavations dry until the structures are poured and Sec. 07500 -- 50 the concrete has set.

Box 354B1 · Dallas, Texas 75235 · - i - TRENCH SAFETY STUDY DENTON TAP ROAD PAVING & DRAINAGE IMPROVEMENTS BELT LINE ROAD TO COTTONWOOD BRANCH CREEK COPPELL, TEXAS INTRODUCTION As authorized on Septen~ber 11, 1987, a Trench Safety Study has been conducted to evaluate the soil conditions and determine the lateral earth pressure parameters required for the design of trench shoring systems for utility line construction for this project. In addition, studies were con- ducted to evaluate maximum allowable backslopes to use for open cut con- struction. FIELD EXPLORATION A total of 23 test borings were drilled along the right-of-way. These borings were drilled on approximately 500 foot centers along the project alignment. The results of these borings are shown on the attached boring logs together with the station number and offset from centerline at which the borings were drilled. Shelby tube soil samples were obtained in the cohesive soil strata and split-spoon samples were obtained in the sand strata. Together with this sampling, Standard Penetration Tests were made at selected sampling depths. Ground water observations were made at each boring location. These data are shown on the respective boring logs together with the estimated ground elevations. JOHN H. HAYNES & ASSOCIATES. ~NC Geotechnical Engineers - 2 - LABORATORY TESTING A number of Atterberg Limit and moisture content tests were performed on selected soil samples and these results are shown on Plate No. 1. Un- confined compressive strength tests were performed on samples of the various clay and sandy clay strata and these results are shown on Plate Nos. 2 and 3. SITE CONDITIONS In general, the alignment was found to be underlain by CL clay and sandy clay soils to depths of about 5 to 12 feet. These CL clay soils have an average high Liquid Limit of about 40 and an average high Plasticity Index (PI) of about 28. In some borings, layers of CH clay were penetrated; however, these were only encountered at borings drilled at Stations 97+40, 104+00, 139+00 and 144+00. These CH clays were mostly encountered within the upper 5 feet. At some stations, the clay and sandy clay extended well below a depth of 12 feet. Sand was generally encountered below the upper clay and sandy clay strata. At Stations 118+00 and 119+00., sand was en- countered from the ground surface to depths of about 14 feet and 25 feet, respectively, where gray shale bedrock was penetrated. Ground water was encountered at depths ranging from about 15 to 20 feet in the area of Station 97+00 to about Station 169+00. Beyond this point, ground water was encountered at depths of about 7 to 12 feet. The ground water table will fluctuate with the seasons and, at time of construction, it could vary several feet from the depths shown on the Boring Logs. RECOMMENDATIONS Based on the results of the test borings and laboratory tests, studies were made of the various methods available for bracing of vertical excavated cuts or backslopin9 of open cuts for use in construction of utility lines for JOHN H. HAYNES ~ ASSOCIATES. Geotechnical Eng,neers - 3 - this project. Braced Vertical Cuts The lateral pressure developed behind shoring will depend on the method of construction. This is illustrated on Plate No. 4. If driven steel sheet- piles are used and the soil is removed after the sheetpiles are in place, then the pressure diagram shown at the bottom of the sheet (Condition B) should be followed using an active and passive design fluid pressure of 60 pcf and 200 pcf, respectively. The recommended passive fluid pressure figure of 200 pcf includes a factor of safety of at least 2.0. On the other hand, if the trench is excavated as the shoring is installed then the upper pressure diagrams should be followed (Condition A). As most of the utility lines will be installed at depths between 5 and 20 feet, it is recommended that the designs be based on three depth ranges (5' to 10', 10' to 15' and 15' to 20'). For these three depth ranges, it is recommended that uniform lateral pressures of 360 psf, 540 psf and 720 psf, respectively, be used in the design of the trench shoring system. Unbraced Sloped Cuts If open cuts are used in lieu of vertical trench cuts, it is recommended that a maximum backslope angle of I to 1 be used for all cuts in clays and sandy clays. If sand is encountered in any open cut excavation, then the cuts should be laid back on a maximum backslope of 2 horizontal to 1 vertical. A combination of open cut and braced vertical cut can be used provided the braced portion is designed for the full height of cut. Temporary Shoring of Roadway Embankment In order to maintain traffic flow, it is understood that the new bridge at Grapevine Creek will be constructed in two phases. While the southbound traffic lanes are being constructed, traffic will be diverted onto the north- JOHN H. HAYNES & ASSOCIATES. ,Nc Geotechnical En.q,neers - 4 - bound lanes. As the bridge will be elevated, a temporary retaining wall will be required to support the southbound embankment. This retaining wall will have to be installed from about Station 112 to Station 120. Referring to our revised report for the Denton Tap Bridge at Meadow Creek Road dated April 1, 1987, Bridge Boring No. I was drilled at about Station 114+30 and Bridge Boring No. 2 was drilled at about Station 116+70. These are the approximate locations of the transition from bridge deck to embankment fill at which points the temporary retaining wall will begin. Referring to the Boring Logs, firm to very firm dark gray shale was encoun- tered at both locations at about elevation 472 feet (approximately 13 feet below existing grade). At these locations, it appears that the depth of fill will be about 8 feet. Referring to the Trench Safety Study report, two additional borings (T-5 and T-6) were drilled at Station 118+00 and Station 119+00, respectively. These borings encountered gray shale at about elevation 475 feet and 465 feet, respectively. It is recommended that the temporary retaining walls consist of either soldier piles and wood logging with the piles being supported by auger- excavated, cast-in-place concrete piers drilled into the underlying gray shale bedrock or steel sheet piles driven to sufficient depths in the clay and sand strata for adequate lateral support. Drilled concrete piers should be designed for lateral resistance in the dark gray shale equal to a uniform passive pressure of 5,000 psf. This figure includes a factor of safety of at least 2.0. The upper 2 feet of dark gray shale should be neglected in determining the required pier pene- tration. Steel sheet piling driven into the clay and sand strata overlying the dark gray shale should be designed for a passive fluid pressure of 200 pcf which includes a factor of safety of at least 2.0. JOHN H. HAYNES ,r,, ASSOCIATES. [r,Jc Geobechnical Engineers - 5 - It is recommended that all fill placed against the temporary retaining wall be composed of compacted sand. The sand should be placed within the 45 degree angle wedge extending from the base to top of the fill. If sand is used as backfill, the wall can be designed for an active fluid pressure of 40 pcf.
