DAMAGES.

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. The estimated quantities of the various classes of work to be done and material to be furnished under this contract are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that the basis for payment under this contract shall be the actual amount of such work done and the material furnished. 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 con- tained in the proposal; provided, however, that in case the actual quantity of any item should become as much as 25g more than, or 25; 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 25/ of the estimated quantity; such revised consideration to be determined by agreement between the parties, otherwise by the terms of this Agreement, as provided under EXTRA WORK. 16. 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 bond. 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. If they increase the amount of work, and the increased 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 established for such work under this contract; 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 recom- pense 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. 17. EXTRA WORK. The term "Extra Work" as used in this contract shall be understood to mean and include all work that may be required by the ENGINEER or OWNER to be done by the CONTRACTOR to accomplish any change, alteration or addition to the work shown upon the plans, or reasonably implied by the specifications, and not covered by the CONTRACTOR'S Proposal, except as provided under Changes and Alterations in Paragraph 16 herein above. It is agreed that the CONTRACTOR shall perform all Extra Work under the direction of the ENGINEER when prp:rxt.i_ with a Written Work Order signed by the Engineer; subject, however, to the right of the CONTRACTOR to require a wr1 en confirmation of such Extra Work Order by the OWNER. It is also agreed that the compensation to be paid the CONTRACTOR for performing said Extra Work 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 agreed upon before the Extra Work is commenced, then the CONTRACTOR shall be paid the "actual field cost" of the work, plus fifteen (15Z) per cent. 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 of all workmen, such as foremen, timekeepers, mechanics and laborers, and materials, supplies, teams, trucks, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges necessarily incurred, if the kind of equipment or machinery be not already on the job, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, and, a rateable proportion of premiums on Construction and Maintenance Bonds, Public Liability and Workmen's Compensation, and all other insurance as may be required by any law or ordinance, or directed by the ENGINEER or OWNER, or by them agreed to. The ENGINEER may direct the form in which accounts of the "actual field cost" shall be kept and 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 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 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 hereincbfined, 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 11'irt,:11 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, 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 (0). The CONTRACTOR will thereby preserve the right to submit the matter of payment to arbi- tration, as hereinbelow provided. 18. PRELIMINARY APPROVAL. No ENGINEER, supervisor, or inspector shall have any power to waive the obligations of this contract for the furnishing by the CONTRACTOR of good material, and of his performing good work as herein described, and in full accordance with the plans and specifications. No failure or omission of any ENGINEER, supervisor or inspector to condemn any defective work or material shall release the CONTRACTOR from the obligations to at once tear out, remove and properly replace the same at any time prior to final acceptance upon the discovery of said defective work, or material; provided, however, that the ENGINEER, his assistant or inspector, shall, upon request of the CONTRACTOR, inspect and accept or reject any material furnished, and in event the material has been once accepted by the ENGINEER, his assistant or inspector, such acceptance shall be binding on the OWNER, unless it can be clearly shown that such material furnished does not meet the specifications for this work. Any questioned work may be ordered taken up or removed for re- examination, by the ENGINEER, prior to final acceptance, and if found not in accordance with the specifications for said work, all expense of removing, re- examination and replacement shall be borne by the CONTRACTOR; otherwise the expense thus incurred shall be allowed as EXTRA WORK, and shall be paid for by the OWNER. 19. DEFECTS AND THEIR REMEDIES. It is further agreed that if the work or any part thereof, or any material brol.jit on the ground for use in the work or selected for the sane, shall be deemed by the ENGINEER as unsuitable or not in conformity with the specifications, 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. 20. TIME AND ORDER OF COMPLETION. It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the CONTRACTOR shall be allowed to prosecute his work at such times and seasons, in such order of precedence, and in such manner as shall be most conducive to economy of construction; provided, however, that the order and time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, plans and specifications and within the time of completion hereafter designated; 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 further agrees that he will commence work within ten (10) days after the date written notice to do so shall have been given to the CONTRACTOR, and will pro- gress therewith so that the work shall be substantially com- pleted in accordance with the terms of this Agreement * within working days after the date of the . written no "dice to commence the work. A "working day" is defined as a calendar day, not including Sundays or any legal holidays, in which weather or other conditions, not under the control of the CONTRACTOR, will permit construction of the principal units of the work for a continuous period of not less than seven (7) hours between .7 :00 a.m. and 6:00 p.m. . By the term "substantially completed" is meant that the structure has been made suitable for use or occupancy and is in condition to serve its intended purpose, but still may require minor miscellaneous work and adjustment. 21. 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, fire, and unusual delays by common carriers, and unavoidable cause or causes beyond the CONTRACTOR'S control, or by any cause which the ENGINEER shall decide justifies the delay, then an extension of time shall be allowed for completing the work, sufficient to compensate for the delay, the amount of the extension to be determined by the ENGINEER; provided, however, that the CONTRACTOR shall give the ENGINEER prompt notice in writing of the cause of such delay. 22. HINDRANCES AND DELAYS. No charge shall be made by the CONTRACTOR for hindrances or delays from any cause (e:;cept where the work is stopped by order of the OWNER) during the progress of any portion of the work embraced in this contract. In case said work shall be stopped by the act of the OWNER, then such expense as in the judgment of the ENGINEER is caused by such stopping of said work shall be paid by the OWNER to the CONTRACTOR. 23. PRICE FOR WORK. In consideration.of the furnishing of all the necessary labor, equipment and material, and the completion of all work by the CONTRACTOR, and on the completion of all work and of the delivery of all material embraced in this contract in full conformity with the specifications and stipulations herein contained, the OWNER agrees to pay the CONTRACTOR the prices set forth in the Proposal hereto attached, marked "Exhibit C ", which has been made a part of this contract. And 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, the attached specifications and requirements of the ENGINEER. 24. PARTIAL PAYMENTS. On or before the 5th day of each month the Engineer shall prepare a statement showing as com- pletely as practicable the total value of work done by the Contractor up to and including the last day of the preceeding month; said statement shall also include the value of all sound materials delivered on the ground that are to be fabricated into the work. The OWNER shall then pay the CONTRACTOR on or before the 10th day of the current month the total amount of the ENGINEER'S 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 further less 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 occur 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 conditions stated in paragraph 26 hereof. 25. FINAL COMPLETION AND ACCEPTANCE. Within ten (10) days after the CONTRACTOR 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 Plans and Specifications, the ENGINEER shall issue to the OWNER and the CONTRACTOR his Certificate of Completion and thereupon it shall be the duty of the OWNER within said ten (10) days, to issue a Certificate of Acceptance of the work to the CONTRACTOR. 26. FINAL PAYMENT. Upon the issuance of the Certificate of Completion, the ENGINEER shall proceed to make final measurements and prepare final statement of the value of all work performed and materials furnished under the terms of this Agreement and shall certify same to the OWNER, who shall pay to the CONTRACTOR on or before the 15th 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. 27. DELAYED PAYMENTS. Should the OWNER fail to make payment to the CONTRACTOR of the sum named in any partial or final statement, when payment -is due, or should the ENGINEER fail to issue any statement on or before the date above provided, 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 eight (8%) per cent per annum from date due as provided in Paragraphs 24 and 26, until fully 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 in paragraph 24, to at any time thereafter treat the contract as abandoned by the OWNER and recover compensation, as provided by paragraph 45 of this contract. 28. ENGINEER'S AUTHORITY AND DUTY. It is mutually agreed between the parties to this Agreement that the ENGINEER shall supervise all work included herein. In order to prevent delays and disputes and to discourage litigation, it is fur- ther agreed by and between the parties to this contract, that if it cannot be otherwise agreed, the ENGINEER shall in all cases determine the amounts and quantities of the several kinds of work, which are to be paid for under this contract, and he shall determine all questions in relation to said work and the construction thereof, and he shall in all cases decide every question which may arise relative to the execution of this contract on the part of said CONTRACTOR, that his estimates and findings shall be the conditions precedent to the right of the parties hereto to arbitration or to any action on the contract, and to any rights of the CONTRACTOR to receive any money under this contract; provided, however, that should the ENGINEER render any decision or give any direction which, in the opinion of either party hereto, is not in accordance with the meaning and intent of this contract, either party may file with said ENGINEER within thirty (O ) days his written objection to the decision or direction so rendered, and by such action may reserve the right to submit the question so raised to arbitration as herein provided. It being the intent of this agreement that there shall be no delay in the execution of the work, and the decision or directions of the ENGINEER as rendered, shall be promptly carried out, and any claim arising therefrom shall be there- after adjusted by arbitration as hereinafter provided. The ENGINEER shall, within a reasonable time, render and deliver to both the OWNER and the CONTRACTOR a written decision on all claims of the parties hereto and on all questions which may arise relative to the execution of the work or the interpretation of the contract, specifications and plans. Should the ENGINEER fail to make such decision within a reasonable time, an appeal to arbitration may be taken as if his decision had been rendered against the party appealing. 29. CONTRACTOR'S DUTY. The CONTRACTOR shall give per- sonal attention to the faithful prosecution and completion of this work and shall be present either in person or by duly authorized representative on the site of the work continually during its progress. He shall maintain an office on or adjacent to the site of the work. 30. CONTRACTOR'S AGENT. The CONTRACTOR during his absence from the work shall keep a competent superintendent or foreman upon the work, fully authorized to act for him in-his absence, and to receive such orders as may be given for the proper continuance of the work. Notice to do any work, to alter work, to cease work which the CONTRACTOR is obligated to do;or concerning any imperfections in work or any material furnished when given to any foreman or agent of the CONTRACTOR in charge of any operation of the work in the absence of the CONTRACTOR shall be considered as notice to the CONTRACTOR, provided any notice given under this paragraph shall be in writing. 31. CHARACTER OF WORKMEN. The CONTRACTOR agrees to employ only orderly, competent and skillful men.to do the work; and that whenever the ENGINEER shall inform him in writing that any man or men on the work are in his opinion, incompetent, unfaithful or disorderly, such man or men shall be discharged from the work and shall not again be employed on the same without the ENGINEER'S written consent. 32. CONSTRUCTION PLANT. The CONTRACTOR shall provide all labor, tools, equipment, machinery and material necessary in the prosecution and completion of this contract where it is not otherwise specifically provided that the OWNER shall furnish the same, and it is also understood that the OWNER shall- not be held responsible for the care, preservation, conservation or protection of any material, tools or machinery or any part of the work until it is finally com- pleted and accepted. 33. RIGHT OF ENGINEER TO MODIFY METHODS AND EQUIPMENT. If at any time the methods or equipment used by the CONTRACTOR are found to be inadequate to secure the quality of work or the rate of progress required under this contract, the ENGINEER may order the CONTRACTOR in writing to increase their safety or improve their character and efficiency, and the CONTRACTOR shall comply with such order. If at any time the working force of the CONTRACTOR is inadequate for securing the progress herein specified, the CONTRACTOR shall, if so ordered in writing increase his force or equipment, or both, to such an extent as to give reasonable assurance of compliance with the schedule of progress. 34. SANITATION. Necessary sanitary conveniences for the use of laborers on the work, properly secluded from public observation, shall be constructed and maintained by the CONTRACTOR in such manner and at such points as shall be approved by the ENGINEER, and their use shall be strictly enforced. 35. CONTRACTOR'S BUILDINGS. The building of structures for housing men, or the erection of tents or other forms of protection, will be permitted only at such places as the ENGINEER shall direct, and the sanitary conditions of the grounds in or about such structures shall at all times be maintained in a manner satisfactory to the ENGINEER. 36. PROTECTION AGAINST ACCIDENT TO EMPLOYEES AND THE PUBLIC. The CONTRACTOR shall maintain such insurance as will protect the Contractor, the Owner, and the Engineer from claims under Workmen's Compensation Acts, and any amendments thereof, and from any other claims for damages from personal injury, including death, which may arise from operations under this Agreement, whether such operations be by himself or by any sub- contractor, or anyone directly or indirectly employed by either of them. Certificate of such insurance shall be filed with the OWNER, if so required, and shall be subject to his approval for adequacy of protection. 37. PROTECTION OF ADJOINING PROPERTY. The said CONTRACTOR shall take proper means to protect the adjacent or adjoining property or properties in any way encountered, or which might be injured or seriously affected by any process of construction, to be undertaken under this Agreement, for any damage or injury by reason of said process of construction; and he shall be liable for any and all claims for such damage on account of his failure to fully protect all adjoining property. 38: PROTECTION AGAINST CLAIMS OF SUB - CONTRACTORS, LABORERS, MATERIALMEN AND FURNISHERS OF MACHINERY, EQUIPMENT AND SUPPLIES. The CONTRACTOR agrees that he will indemnify and save the OWNER harmless from all claims growing out of the lawful demands of sub - contractors, laborers, workmen, mechanics, materialmen and furnishers of machinery and parts thereof, equipment, power, tools, and all supplies, including commissary, incurred in the furtherance of the performance of this contract. When so desired by the OWNER, the CONTRACTOR shall furnish satisfactory evidence that all obligations of the nature hereinabove designated have been paid, discharged or waived. If the CONTRACTOR fails so to do, then the OWNER may at the option of the CONTRACTOR either pay unpaid bills, of which the OWNER has written notice, direct, or withhold from the CONTRACTOR'S unpaid compensation a sum of money deemed reasonably sufficient to liquidate any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully discharged, whereupon payments to the CONTRACTOR shall be resumed in full, in accordance with the terms of this contract, but in no event shall the provisions of this sentence be construed to impose any obligation upon the OWNER to either the CONTRACTOR or his SURETY. 39. PROTECTION AGAINST ROYALTIES OR PATENTED INVENTION. The CONTRACTOR shall protect and_save harmless the OWNER from all and every demand for damages, royalties or fees on any patented invention used by him in connection with the work done or material furnished under this contract; provided, however, that if any patented material, machinery, appliance or invention is clearly specified in this contract, then, and in that event, the cost of procuring the rights of use and the legal release or indemnity shall be borne and paid by the OWNER, unless such cost can be determined and included in the bid price at the time the proposal is submitted. 40. LAWS AND ORDINANCES. The CONTRACTOR shall at all times observe and comply with all Federal, State and local laws, ordinances and regulations, which in any manner affect the contract or the work, and shall indemnify and save harm- less the OWNER against any claim arising from the violation of any such laws and ordinances, whether by the CONTRACTOR or his employees. In case the OWNER is a body politic and corporate, the law from which it derives its powers, insofar as the same regulates the objects for which, or the manner in which, or the conditions under which, the OWNER may enter into contract, shall be controlling, and shall be considered as part of this Contract, to the same effect as though embodied herein. 41. LIQUIDATED DAMAGES FOR DELAY. And the CONT$3r't;`TO'd ees that time is of the essence of this contract,`and that fo ach day of delay beyond the number of working days - herei'..agreed upon for the completion of the wgf'k herein - specifi and contracted for (after due alloud`nce for such extension time as is provided for under,gxtension of Time hereinabove the OWNER may withhold per nently from the * CONTRACTOR'S t'o al compensation, the s of Dollars ($ as stS'ulated liquidated damages 42.

ASSIGNMENT AND SUBLETTING. The CONTRACTOR further agrees that he will retain personal control and will give his personal attention to the fulfillment of this contract and that he will not assign by Power of Attorney, or otherwise, nor sublet said contract without the written consent of the OWNER, and that no part or feature of the work will be sublet to anyone objectionable to the ENGINEER or the OWNER. The CONTRACTOR further agrees that the subletting of any portion or feature of the work, or materials required in the perform- ance of this contract, shall not relieve the CONTRACTOR from his full obligations to the OWNER, as provided by this Agreement. 44. ABANDONMENT BY CONTRACTOR. In case the CONTRACTOR should abandon and fail or refuse to resume work within ten (10) days after written notification from the OWNER, or the ENGINEER, or if the CONTRACTOR fails to comply with the orders of the ENGINEER, when such orders are consistent with this Contract, or with this Agreement, or with the Specifications hereto attached, then, and in that case, the Surety on the bond 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 construction 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 paragraph 17, Extra Work); it being under- stood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. 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: (a) 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 the expenses 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 co,trsct, if the same had been completed by said CONTRACTOR, then tic CONTRACTOR and /or his SURETY shall pay the amount of such excess to the OWNER: or: (b) The OWNER under sealed bids, after five (5) days notice published one or more times in a newspaper having a 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 of 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. 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 25 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, mat;ria1s 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 CONTRALTO, and his Surety subject only to the duty of the OWNER to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the OWNER may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the CONTRACTOR and his Surety. Such sale may be made at either public or private sale, with or without notice, as the OWNER may elect. The OWNER shall release any machinery, equipment, tools, materials or supplies, which remain on the work, and belong to persons other than the CONTRACTOR, or his Surety, to their proper OWNERS. 45. 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 ground that have not been included in pay - ments 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, (Exhibit C), 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 pre- vious 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 befora thirty (30) days after the date of the notifi- cation by the CONTRACTOR the balance shown by said final statement as due the CONTRACTOR, under the terms of this Agreement. 46. BOND. It is further agreed by the parties to this contract TEat the CONTRACTOR will execute a bond in the sum of WA, Coati Dollars ( Q' ) for the satis- factory performance of the work in accordance with this con- tract in the form provided for this purpose, and it is agreed that this contract shall not be in effect until such bond is furnished and approved by the OWNER. 47. 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 a reasonable time after the ENGINEER has given any direction, order or instruction to which the CONTRACTOR desires to take exception. The ENGINEER shall reply 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 arbitra- tion shall be filed with the ENGINEER and the OWNER in writing within ten (10) days after the date 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 as follows: sstraoter etiail bs voop'sdba for Will 4i•stdi'a "0* it tai t$a to the psa jeas for s prsloi of me roar aim 4a%a of final afNptellM. 48. ADEQUACY OF DESIGN. It is understood that the OWNER has selected the ENGINEER named in this Agreement to prepare the plans and specifications, and all Supplements thereto; and agreed that the OWNER will be responsible for the adequacy of the design, sufficiency of the plans and specifications, and the safety of the structure, provided the CONTRACTOR has complied with said plans and specifications, all modifications thereof, and additions and alterations thereto, approved by the ENGINEER. The burden of proof shall be upon the CONTRACTOR to show that he has complied with this contract, said plans, specifications, and all modifications thereof, and all additions and alterations thereto. 49. 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 21.401matrawlipse MN *OW Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of. the ENGINEER shall be final and binding on him. Should the other party fail to choose an arbiter within ten (10) days, the ENGINEER shall appoint such arbiter, Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take ex parte proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any question submitted to arbitration under this contract shall be a condition precedent to any right of legal action. The 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, and shall not be open to objection on account of the form of proceedings or award.

The contract form will be the Standard Form of Agreement of the Texas Section of the American Society of Civil 2ngineers. SCOPE OF WORK, INSTRUCTIONS, INFORMATION FOR BIDDERS The Proejct comprises storm water drainage works, additional protection for small boats, stabilizing the south section of the existing breakwater by a concrete ca..in;, the com.letion of o .- incidental works The Owner may find it necessary before final award of the contract or thereafter, to make substantial 'changes in the scope of the work to be done by (1) the elimination of certain items on which proposals Gave been received and (2) the inclusion of new work in lieu of that eliminated. The Contractor agrees that no c1ai..: for liquidated da,,aEes and anticipated profits shall be made for any item of the work eliminated. Lie Contractor agrees that any major item of work added to the project shall be paid for on the basis of his unit price bid where such unit,price can be applied to the added work. Storm ',Etter Drainage: Storm sewers are to be constructed, larger inlets added to the storm sewers on Chaparral and Mesquite Streets, two storm water pumping stations to be constructed, one at Doddridge Street between Ocean Drive ('eater Street) and Shoreline Boulevard, and the second at ' F;ater and Power Streets. Outlets from these pumping stations are to be constructed across the hydraulic fill and sea wall to the Bay. Protection for Small Boats: One pier is to be constructed to complete the north section of the boat basin. -10- Capping South Breakwater: A concrete cap is to be constructed on the south section of the rock jetty and this cap connected with the sea wall by means of a concrete walk. Groins: Sheet piling groins are to be constructed south of the south end of the rock jetty. Sodding: Necessary sodding or other treatment of the areas around the pump stations will be carried out. Lines and Grades: All parts and units of the project shall be ccu- structed in accordance' with the plans and to the limes a.d grades established by the engineer and shall be maiLitii_.ed until final acceptance of the project. Storage and Handling of Materials: Iaterials entering into the work shall be handled and stored in such a manner that their quality and identity will be maintained. Any material to be incorporated into the work, if used temporarily for construction purposes, shall be in- spected and approved by the 'Engineer after any temporary use and before being incorporated permanently into the work. Adequacy of Construction Equipment: All equipment for the project or directly affecting material entering into the work shall be adequate to do the work for which it is called upon, shall be in first class working and producing condition and shall be acceptable to the Engineer. Equipment which, through its failure, would delay and affect the strength and stability of the work shall be supplemented by stand -by equipment; this applies in parti- cular to concrete producing equipment, concrete placing equipment, trucks, vibrators, pumping equipment, etc. Tools used on the work shall be standard for the duty required and in good condition. Conduit Des Win: .inor variations in ai:Gensibus or shape of forms for monolithic concrete sewers will be permitted upon written approval of the Engineer. Such variations shall maintain the same hydraulic and other properties as the original Obstructions: On the East Side of Water Street from Starr Street • and ext�.iding five or six blocks to the North, a portion of the ,,Alb and pavement was washed out during a hurric.-,::e a nunber of • years ago: This area was backfilled with what- ever we,: .available at the time and the Contractor in exc.:vat- ing for tiie storm sewer may expect to find considerable debris al.rug this stretch of the work. Manufacturers' Data: here a manufacturer of equipment quotes more than one prospective bidder on items for which catalogs and technical data are to be submitted, it will be acceptable for the manufacturer to file one set of such information and data with the Engineer prior to the time of opening bids. This will be considered as complying with the requirement for the filing of such data with each proposal. Protection of Existing Seawall Structures: The existing bay front structures such as the sea- wall, splash areas, pavement, parkway, etc., shall be fully . protected against damage or defacement due to construction under this project. Where the outfall storm sewer goes under the roadway, care.shall be taken that no settlement or movement of the seawall occurs. Excavation on the outside of the seawall for this storm sewer outlet shall be held to the absolute minimum width consistent with the necessary construction. Among the structures to be built, and for which materials will have to be carried over the splash area and sea wall may be the following: (1) The outfall storm sewers (2) The Taylor Street Fier and Steps. (3) Capping the South Jetty. (4) Construction of groins. In carrying the material and eciuiprnent over existi.;g, structures to build these or any other items of the proect, - 12 - the curb, splash areas and seawall shall be thoroughly Ho- tected by tight substantial platforms sheeted with material not less than two (2) inches in thickness. These platfcrms shall be maintained sound and intact until the constroctio in each instance has been completed. After completion of a structure for which the p_otforc has been built, the platform shall be removed and the area thoroughly cleaned up. Where concrete, mortar, or other material has been spilled on the existing structure, the same shall be carefully removed and the surface of the exist- ing structure thoroughly rubbed down to erase all signs of defacement. The sliding or rolling of material on existing concrete construction will not be permitted. Should any defacement or damage occur to existing con- crete, the area where such damage occurs shall be cut back at right angles to the surface of the concrete and to such a depth that a workmanlike and sound replacement of the surface can be made and such replacement be tied into the original concrete by means of suitable dowels set in holes drilled in the original concrete at intervals to be determined by the Engineer. The Engineer shall at all times have the right to stop the work where it appears that damage is going to be caused to the existing structures through carelessness and insuffi- cient protective measures and the w ork shall not be resumed until proper protective measures, approved by the Engineer, have been taken. The handling of heavy materials, such as steel sheet piling and creosoted timber and piling, across the seawall will not be permitted. These materials may be handled off of the urge dock, or the Municipal Wharf. Removal of Existing Structures: There existing surface structures are to be ner,;veu, such as ,Javement, sidewalks, driveways, curb and guL : , etc., the width removed shall not be in excess of that specified for trench midths at the top of the pipe, except as permitted or uirected by the Engineer, to conform to adjacent markings or joints in the structure, except that where pavement is cut, the same shall be cut back six (6) inches beyond the trench on each side and replaced, such cutting back to be done after backfill has been placed and tamped. - 13 - Removal and Replacement of Sod, Shrubbery, Plants, etc.: ?here sod, shrubbery, plants, etc., are removed in making an excavation, such areas as are backfilled shall have the same replaced in good condition, or other sod, shrubbery, plants, etc., of the same kind and in good condition placed in its stead. The sod shall be removed in one layer ana shall be carefully stored and protected from the sun. Shrub- bery, plants, etc., shall be removed with a ball of dirt about their roots wrapped in burlap and shall be carefully stored and protected. Protection of Trees, Plants, Shrubbery, etc.: Where trees, plants, shrubbery, etc., are adjacent to the line of the work and are not to be removed, the contractor shall protect such growth by substantial wooden boxes and guards and shall not permit ,machinery or employees to scrape, tear the limbs from, or darna €e, or attach guy cables to the same. If, in the opinion of the Engineer, such trees, plants, shrubbery, etc., would be damaged by the machinery, etc., hand excavation may be required. The con- tractor shall be responsible for all damages to the trees, plants, shrubbery, etc. Utilities: Where sewer, water, gas pipes or other public utili- ties are encountered, they shall be protected by the contractor who will be responsible for crossing therm in such a manner as not to cause any damage. Any damages occurring because of the contractors' work will be repaired by the contractor at his expense. Where such utilities are encountered and are required to be removed or relocated because of the work, the moving or shifting of the same shall be done by the contractor at his expense. Removal or Passing of Buildins, Railroads, Highways, Pipe Lines: The Contractor shall make all necessary arrangements for maintaining suitable entrance crossing to all buildings adjacent to the work, passing, or removing and replacing fences, walks, roads, highways, railroads, bridges, buildings, telephone and telegraph lines, power lines, pipe lines, conduits, etc., and shall include the cost of such work in his unit price bid on the pipe selected, in place. All structures such as above mentioned shall be replaced by the contractor in as good condition as before the contractor enters on the site and in full conformity with rules agreed upon between the contractor and the Owner of such structures. - 14 - All work shall be done in a manner so as to cause the least amount of delay in use by the Owner and with the least amount of inconvenience to the public. Exception to the above: Vhere water and gas mains and services owned by the City are encountered and have to be shifted or moved, the shifting and moving. will be performed by the Superintendent of Water Works of the City of Corpus Christi. Barricades and Danger Signs: The Contractor shall provide, erect and maintain all necessary barricades, suitable and sufficient lights, danger signs and signals, provide a sufficient number of watchmen and take all necessary precautions for the protection of the work and the safety of the public.

Reinforcement shall be thoroughly secured and approved by the Engineer. Handling and Conveying: Concrete shall be handled from the mixers to the place of deposit as rapidly as practicable by methods which shall pre- vent the separation of or loss of the ingredients. It shall be deposited as nearly as practicable in its final' position in the forms. It shall not be run along nor raked along the forms, but it shall be deposited so as to maintain, until the completion of the unit, a plastic surface approximately horizontal. Forms for walls, or other thin sections of con- siderable height, shall be provided with openings or other devices that will permit the concrete to be placed in a manner that will avoid accumulation of hardened concrete on the forms or metal reinforcement. Chutes: When concrete is conveyed by chuting, the plant shall be of such size as to insure a practically continuous sliding in the chute, and of such design as will permit a free and ready movement of the discharge end of the chute along the forms, permitting the deposit of the concrete in place without raking of same. The angle of the chute with the horizontal shall be such as to allow the concrete to flow without separation of the ingredients, and the delivery end of the chute shall be as close as is possible to the point of deposit. The chute shall be thoroughly flushed with water before and after each run, or thoroughly cleaned by other means after each run, and water used for this purpose shall be discharged clear of the work. Concrete chutes shall be covered where necessary to prevent loss of material, and shall be of metal or full; metal lined. Vibrating Concrete: Concrete, during and immediately after depositing, shall be thoroughly compacted by means of internal vibrators of an approved type and size. The concrete shall thoroughly be worked around the reinforcement and among the embedded fixtures and into the corners of the forms. The following paragraph shall apply to thin slabs and walls at points where thin slabs are deposited without requiring forms on both faces: Concrete shall be thoroughly tamped and puddled around the reinforcing and into position. Depositing Concrete Slabs: On the bottom and sloping slabs of structures, before depositing concrete, the earth shall be hand dressed to a firm bearing. If excavation is carried below grade, it shall be backfilled with concrete. Before depositing such slabs where shown on the pia.us, the earth surface on which the concrete is to be laid shall be covered with a layer of sisal kraft paper, or an approved equal, well 1%.pped and fastened firmly in position. The concrete shall be deposited on top of this waterproof paper. This waterproof paper shall conform with General Requirements, Paragraph 2, A.S.T.M. Designation C171 -42T. Joining New Concrete to Old: Before depositing concrete against that which has set, the forms shall be retightened. Smooth surfaces of the set concrete shall be roughened to a depth of one -half (1/2) inch, thoroughly cleaned of foreign matter and laitance and saturated with water. To insure bond, the new concrete placed in contact with hardened or partially hardened concrete shall contain an excess of mortar. If required, the cleaned and saturated surfaces of the hardened concrete, including vertical and inclined surfaces, shall first be covered with a sprinkling of neat cement, against which the new concrete shall be placed. Construction joints shall be located as approved by the Engineer, and formed so as to least impair the appearance and strength of the structures. Unless specified otherwise in writing by the Engineer, no concrete shall be deposited against earth side walls. Where it is desired to cast concrete against forms which are to be left in place, such process shall be subject to the approval of the Engineer. Removal of Water: Water shall be removed from the excavation before -.the concrete is deposited, Any flow of water into the excca.vation shall be directed through proper side drains to a sump, or removed by other approved methods which avoid washing the freshly deposited concrete. After the concrete has thoroughly hardened, water vent pipes shall be filled by grouting. - 12 - Curing Concrete: Curing the concrete on this project is considered to be of major importance. Exposed surfaces of the concrete shall be kept wet continuously for a period of not less than seven (7) days after the time of depositing concrete. Concrete shall be cured with wet mats, or an equally efficient method approved by the Engineer. Luring the specified, finishing operations, such c.oueriig, when required, shall be removed only for a minimum period of time and over a minimum area necessary. Mats used in curing shall be firmly anchored in place at all times. Concreting shall not be commenced until approved mea..s for curing have been fully provided. Working on Concrete: No materials or equipment shall be stored on the walls or floor of structural members at any time, and forms or workmen shall not be allowed thereon while curing except for finishing and curing operations. When it becomes necessary, in the opinion of the Engineer, for loads to be supported on such members, or for workmen to operate therefrom, such protection of surfaces and bracing under slabs and beams shall be installed as the Engineer may direct. Finishing: Each and every part of the concrete work shall be care- fully and neatly finished. Immediately after the removal of forms, all surfaces, whether to be exposed or not, shall have all honeycombed areas cut out and replaced or pointed up as required by the Engineer, using cement mortar of the same mixture as that used in the concrete.
