DEFINITIONS OF TERMS 1.01 OWNER, CONTRACTOR AND ENGINEER.

The term ENGINEER means the ENGINEER or his duly authorized representative. The ENGI- NEER shall be understood to be the ENGINEER of the OWNER, and nothing contained in the Contract Documents shall create any contractual or agency relationship between the ENGINEER and the CONTRACTOR. 1.02 CONTRACT DOCUMENTS. The Contract Documents shall consist of the Notice to Contractors (Advertisement), Special Conditions (Instructions to Bidders), Proposal, signed Agreement, Performance and Payment Bonds (when required), Special Bonds (when required), General Conditions of the Agreement, Technical Specifications, Plans, and all modifications thereof incorporated in any of the documents before the execution of the agreement. The Contract Documents are complementary, and what is called for by any one shall be as binding as if called for by all. In case of conflict between any of tho Contract Documents, priority of interpretation shall be in the following order: Signed Agreement, Performance and Payment Bonds, Special Bonds (if any), Proposal, Special Conditions of Agreement, Notice to Contractors, Technical Specifications. Plans, and General Conditions of Agreement. 1.03 SUB-CONTRACTOR. The term Sub-Contractor, as employed herein, includes only those having a direct contract with the CONTRACTOR and it includes one who furnishes material worked to a special design according to the plans or specifications of this work, but does not include one who merely furnishes material not so worked. 1.04 WRITTEN NOTICE. Written notice shal'l be deemed to have been duly served if delivered in ;~erson to the individual or to a member of the firm or to an officer of the corporation for whom it is intended, or if delivered at or sent by registered, mail to the last business address known to him who gives the notice. 1.05 WORK. The CONTRACTOR shall provide and pay for all materials, supplies, machin- ery, equipment, tools, superintendence, labor, services, insurance, and all water, light, power, fuel, transportation and other facilities necessary for the execution and completion of the work covered by the contract documents. Unless otherwise specified, all materials shall be new and both workmanship and materials shall be of a good quality. The CONTRACTOR shall, if required, furnish satisfactory evidence as to t. he kind and quality of materials. Materials or work described in words which so applied have a well known technical or trade meaning shall be held to refer to such recognized standards. 1.06 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", herein. 1.07 WORKING DAY. A "Working Day" is defined as any day not including Saturdays, 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 period of not less than seven (7) hours between 7:00 a.m. and 6:00 p.m. 1.08 CALENDAR DAY. "Calendar Day" is any day of the week or month, no days being excepted. 1.09 SUBSTANTIALLY COMPLETED.

G-I ~ ~, :'~ ~'~'o". -'-~ 2. RESPONSIBILITIES OF THE ENGINEER AND THE CONTRACTOR 2.01 OWNER-ENGINEER RELATIONSHIP. The ENGINEER will be the O¥~,~ER'S representative during construction. The duties, responsibilities and limitations of authority of the ENGINEER as the OWNER'S representative during construction are as set forth in the Contract Documents and shall not be extended or limited without written consent of the OWNER and ENGINEER. The ENGINEER will advise and consult with the OWNER, and all of OWNER'S instructions to the CONTRACTOR shall be issued through the ENGINEER. 2.02 PROFESSIONAL INSPECTION BY ENGINEER. The ENGINEER shall make periodic visits to the site to familiarize himself generally with the progress of the executed work and to determine if such work generally meets the essential performance and design features and the technical and functional engineering requirements of the Contract Documents; provided and except, however, that the ENGINEER shall not be responsible for making an~' detailed, exhaus- tive, comprehensive or continuous on-site inspection of the quality or quantity of the work or be in any way responsible, directly or indirectly, for the construction means, methods, techniques, se- quences, quality, procedures, programs, safety precautions or lack of same incident thereto or in connection therewith. Notwithstanding any other provision of this agreement or any other Contract Document, the ENGINEER shall not be in any way responsible or liable for any acts, errors, omissions or negligence of the CONTRACTOR, any subcontractor or any of the CONTRACTOR'S or subeontraetor's agents, servants or employees or any other person, firm or corporation perform- ing or attempting to perform any of the work. 2.03 PAYMENTS FOR WORK. The ENGINEER shall review CONTRACTOR'S applications for payment and supporting data, determine the amount owed to the CONTRACTOR and approve, in writing, payment to CONTRACTOR in such amounts; such approval of payment to CONTRAC- TOR constitutes a representation to the OWNER of ENGINEER'S professional judgment that the work has progressed to the point indicated to the best of his knowledge, information and belief, but such approva, l of an application for payment to CONTRACTOR shall not be deemed as a representatior~ by ENGINEER that ENGINEER has made any examination to determine how or for what purpose CONTRACTOR has used the moneys paid on account of the Contract price. 2.04 INITIAL DETERMINATIONS. The ENGINEER initially shall determine all claims, disputes and other matters in question between the CONTRACTOR and the OWNER relating to the execution or progress of the work or the interpretation of the Contract Documents and the ENGINEER'S decision shall be rendered in writing within a reasonable time. Should the ENGI- NEER fail to make such decision within a reasonable time, appeal to arbitration may be taken as if his decision had been rendered against the party appealing. 2.05 OBJECTIONS. In the event the ENGINEER renders any decision which, in the opinion of either party hereto, is not in accordance with the meaning and intent of this contract, either party may file with the ENGINEER within thirty days his written objection to the decision, and by such action may reserve the right to submit the question so raised to arbitration as hereinafter provided. 2.06 LINES AND GRADES. Unless otherwise specified, all lines and grades shall be furnished by the ENGINEER or his representative. Whenever necessary, construction work shall be suspended to permit performance of this work, but such suspension will be as brief as practicable and the CONTRACTOR shall be allowed no extra compensation therefor. The CONTRACTOR shall give the ENGINEER ample notice of the time and place where lines and grades will be needed. All stakes, marks, etc., shall be carefully preserved by the CONTRACTOR, and in case of careless destruction or removal by him or his employees, such stakes, marks, etc., shall be replaced at the CONTRACTOR'S expense. 2.07 CONTRACTOR'S DUTY AND SUPERINTENDENCE. The CONTRACTOR shall give adequate attention to the faithful prosecution and completion of this contract and shall keep on the work, during its progress, a competent superintendent and any necessary assistants. The superintendent shall represent the CONTRACTOR in his absence and all directions given to him shall be as binding as if given to the CONTRACTOR. G-2 The CONTRACTOR is and at all times shall remain an independent contractor, solely responsible for the manner and method of completing his work under this contract, with full power and authority to select the means, method and manner of performing such work, so long as such methods do not adversely affect the completed improvements, the OWNER and ENGINEER being interested only in the result obtained and conformity of such completed improvements to the plans, specifications and contract. Likewise, the CONTRACTOR shall be solely responsible for the safety of himself, his employ- ees and other persons, as well as for the protection of the safety of the improvements being erected and the property of himself or any other person, as a result of his operations hereunder. Engineer- ing construction drawings and specifications as well as any additional information concerning the work to be performed passing from or through the ENGINEER shall not be interpreted as requiring or allowing CONTRACTOR to deviate from the plans and specifications, the intent of such drawings, specifications and any other such instructions being to define with particularity the agreement of the parties as to the work the CONTRACTOR is to perform. CONTRACTOR shall be fully and completely liable, at his own expense, for design, construction, installation and use, or non-use, of all items and methods incident to performance of the contract, and for all 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 construction, 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. No verbal agreement or conversation with any officer, agent or employee of the OWNER or ENGINEER either before or after the execution of this contract, shall affect or modify any of the terms or obligations herein contained. 2.09 CHARACTER OF WORKMEN. The CONTRACTOR agrees to employ only orderly and competent men, skillful in the performance of the type of work required under this contract, to do the work: and agrees that whenever the ENGINEER shall inform him in writing that any man or men on the work are, in his opinion, incompetent, unfaithful or disorderly, such man or men shall be discharged from the work and shall not again be employed on the work without the ENGINEER'S written consent. 2.10 CONTRACTOR'S BUILDINGS. The building of structures for housing men, or the erection of tents or other forms of protection, will be permitted only at such places as the ENGINEER shall direct, and the sanitary conditions of the grounds in or about such structures shall at all times be maintained in a manner satisfactory to the ENGINEER. 2.11 SANITATION. Necessary sanitary conveniences for the use of laborers on the work, properly secluded from public observation, shall be constructed and maintained by the CONTRAC- TOR in such manner and at such points as shall be approved by the ENGINEER, and their use shall be strictly enforced. 2.12 SHOP DRAWINGS. The CONTRACTOR shall submit to the ENGINEER. with such promptness as to cause no delay in his own work or in that of any other Contractor. four checked copies, unless otherwise specified, of all shop and. or setting drawings and schedules required for the work of the various trades, and the ENGINEER shall pass upon them with reasonable 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. No failure or omission of the ENGINEER to discover, object to or condemn any defective work or material shall release the CONTRACTOR from the obligations to fully and properly perform the contract, including without limitations, the obligation to at once tear out, remove and properly replace the same at any time prior to final acceptance upon the discovery of said defective work or material: provided, however, that the ENGINEER shall, upon request of the CONTRAC- TOR, inspect and accept or reject any material furnished, and in event the material has been once accepted by the ENGINEER, such acceptance shall be binding on the OWNER, unless it can be clearly shown that such material furnished does not meet the specifications for this work. Any questioned work may be ordered taken up or removed for re-examination, by the ENGINEER, prior to final acceptance, and if found not in accordance with the specifications for _ said work, all expense of removing, re-examination and replacement shall be borne by the CONTRACTOR, otherwise the expense thus incurred shall be allowed as EXTRA WORK, and shall be paid for by the OWNER; provided that, where inspection or approval is specifically required by the specifications prior to performance of certain w~rk, should the CONTRACTOR proceed with such work without requesting prior inspection or a~,oroval 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 ma)' see fit, in the line, grade, form, dimensions, plans or materials for the work herein contemplated, or an)' 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 "Measurement 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. GENERAL OBLIGATIONS AND RESPONSIBILITIES 3.01 KEEPING OF PLANS AND SPECIFICATIONS ACCESSIBLE. The ENGINEER shall furnish the CONTRACTOR with an adequate and reasonable number of copies of all plans and specifications without expense to him, and the CONTRACTOR shall keep one copy of the sa,.~e constantly accessible on the work, with the latest revisions noted thereon. 3.02 OWNERSHIP OF DRAWINGS. All drawings, specificati~s and copies thereof furnished by the ENGINEER shall not be reused on other work, and, with the exception of the signed contract sets, are to be returned to him on request, at the completion of the work. All models are the property of the OWNER. 3.03 ADEQUACY OF DESIGN. It is understood that the OWNER believes it has employed competent engineers and designers. It is, therefore, agreed that the OWNER shall be responsible for the adequacy of the design, sufficiency of the Contract Documents, the safety of the structure and the practicability of the operations of the completed project; provided the CONTRACTOR has complied with the requirements of the said Contract Documents, all approved modifications thereof, and additions and alterations thereto approved in writing by the OWNER. The burden of proof of such compliance shall be upon the CONTRACTOR to show that he has complied with the said requirements of the Contract Documents, approved modifications thereof and all approved additions and alterations thereto. 3.04 RIGHT OF ENTRY. The OWNER reserves the right to enter the property or location on which the works herein contracted for are to be constructed or installed, by such agent or agents as he may elect, for the purpose of inspecting the work, or for the purpose of constructing or installing such collateral work as said OWNER may desire. 3.05 COLLATERAL CONTRACTS. The OWNER agrees to provide by separate contract or otherwise, all labor and material essential to the completion of the work specifically excluded from this contract, in such manner as not to delay the progress of the work, or damage said CONTRAC- TOR, except where such delays are specifically mentioned elsewhere in the Contract Documents. 3.06 DISCREPANCIES AND OMISSIONS. It is further agreed that it is the intent of this contract that all work must be done and all material must be furnished in accordance with the generally accepted practice, and in the event of any discrepancies between the separate contract documents, the priority of interpretation defined under "Contract Documents" shall govern. In the event that there is still any doubt as to the meaning and intent of any portion of the contract, specifications or drawings, the ENGINEER shall define which is intended to apply to the work. 3.07 EQUIPMENT, MATERIALS AND CONSTRUCTION PLANT. The CONTRACTOR shall be responsible for the care, preservation, conservation, and protection of all materials, supplies, machinery, equipment, tools, apparatus, accessories, facilities, all means of construction, and any and all parts of the work, whether the CONTRACTOR has been paid, partially paid, or not paid for such work, until the entire work is completed and accepted. G-5 ~) ...... ~ ....... .~,-~ ,~-, 3.08 DAMAGES. In the event the CONTRACTOR is damaged in the course of the comple- tion of the work by the act, neglect, omission, mistake or default of the O~'.~ER, or of the ENGINEER, or of any other CONTRACTOR employed by the OWNER upon the work, thereby causing loss to the CONTRACTOR, the OWNER agrees that he will reimburse the CONTRACTOR for such loss. In the event the OWNER is damaged in the course of the work by the act, negligence, omission, mistake or default of the CONTRACTOR, or should the CONTRACTOR unreasonably delay the progress of the work being done by others on the job so as to cause loss for which the OWNER becomes liable, then the CONTRACTOR shall reimburse the OWNER for such loss. 3.09 PROTECTION AGAINST ACCIDENT TO EMPLOYEES AND THE PUBLIC. The CONTRACTOR shall at all times exercise reasonable precautions for the safety of employees and others on or near the work and shall comply with all applicable provisions of Federal, State, and Municipal safety laws and building and construction codes. :-MI machinery and equipment, and other physical hazards shall be guarded in accordance with the "Manual of Accident Prevention in Construction" of the Associated General Contractors of America except where incompatible with Federal, State, or Municipal laws or regulations. The CONTRACTOR shall provide such machinery guards, safe walkways, ladders, bridges, gangplanks, and other safety devices. The safety precautions actually taken and their adequacy shall be the sole responsibility of the CONTRACTOR, acting at his discretion as an independent contractor. 3.10 PERFORM:~NCE :4aN'D PAYMENT BONDS. Unless otherwise specified, it is further agreed by the parties to this Contract that the CONTRACTOR will execute separate performance and payment bonds, each in the sum of one hundred (100) percent of the total contract price, in standard forms for this purpose, guaranteeing faithful performance of the work and the fulfillment of any guarantees required, and further guaranteeing payment to all persons supplying labor and materials or furnishing him any equipment in the execution of the Contract, and it is agreed that this Contrac~ shall not be in effect until such performance and payment bonds are furnished and approved by the OWNER. Unless otherwise approved in writing by the O'~.~ER, the surety company underwriting the bonds shall be acceptable according to the latest list of companies holding certificates of authority from the Secretary of the Treasury of the United States. Unless otherwise specified, the cost of the premium for the performance and payment bonds shall be included in the CONTRACTOR'S proposal. 3.11 LOSSES FROM NATURAL CAUSES. Unless otherwise specified, all loss or damage to the CONTRACTOR arising out of the nature of the work to be done, or from the action of the elements, or from any unforeseen circumstance in the prosecution of the same, or from unusual obstructions or difficulties which may be encountered in the prosecution of the work, shall be sustained and borne by the CONTRACTOR at his own cost and expense. 3.12 PROTECTION OF ADJOINING PROPERTY. The said CONTRACTOR shall take proper means to protect the adjacent or adjoining property or properties in any way encountered, which might be injured or seriously affected by any process of construction to be undertaken under this Agreement, from 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. The CONTRACTOR agrees to indemnify, save and hold harmless the OWNER and ENGINEER against any claim or claims for damages due to any injury to any adjacent or adjoining property, arising or growing out of the performance of the contract; but any such indemnity shall not apply to any claim of any kind arising out of the existence or character of the work. 3.13 PROTECTION AGAINST CLAIMS OF SUB-CONTRACTORS, LABORERS, MATER- 1ALMEN AND FURNISHERS OF MACHINERY, EQUIPMENT AND SUPPLIES. The CONTRAC- TOR agrees that he will indemnify and save the OV~ER and ENGINEER 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 directly any unpaid bills, of which the OWNER has written notice, or withhold from the CONTRACTOR'S unpaid compensation a sum of money deemed reasonably sufficient to liquidate any and all such lawful claims until satisfactory evidence is furnished that all liabilities have been fully discharged, whereupon payments to the CONTRACTOR shall be resumed in full, in accordance with the terms of this contract, but in no event shall the provisions of this sentence be construed to impose any obligation upon the OWNER by either-the CONTRACTOR or his Surety. 3.14 PROTECTION AGAINST ROYALTIES OR PATENTED INVENTION. The CON- TRACTOR shall pay all royalties and license fees, and shall provide for the use of any design, device, material or process covered by letters patent or copyright by suitable legal agreement with the patentee or owner. The CONTRACTOR shall defend all suits or claims for infringement of any patent or copyright rights and shall indemnify and save the OWNER and ENGINEER harmless from any loss on account thereof, except that the OWNER shall defend all such suits and claims and shall be responsible for all such loss when a particular design, device, material or process or the product of a particular manufacturer or manufacturers is specified or required by the OWNER; provided, however, if choice of alternate design, device, material or process is allowed to the CONTRACTOR, then CONTRACTOR shall indemnify and save OWNER harmless from any loss on account thereof. If t~:e material or process specified or required by the OWNER is an infringe- ment, the CONTRACTOR shall be responsible for such loss unless he promptly gives such information to the OWNER. 3.15 LAWS AND ORDINANCES. The CONTRACTOR shall at all times observe and comply with all Federal, State and local laws, ordinances and regulations, which in any manner affect the contract or the work, and shall indemnify and save harmless the OWNER and ENGINEER against any claim arising from the violation of any such laws, ordinances, and regulations whether by the CONTRACTOR or his employees, except wliere such violad~ions are called for by the provisions of the Contract Documents. If the CONTRACTOR observes that the plans and specifications are at variance therewith, he shall promptly notify the ENGINEER in writing, and any necessary changes shall be adjusted as provided in the contract for changes in the work. If the CONTRAC- TOR performs any work knowing it to be contrary to such laws, ordinances, rules and regulations, and without such notice to the ENGINEER, he shall bear all costs arising therefrom. In case the OWNER is a body politic and corporate, the law from which it derives its powers, insofar as the same regulates the objects for which, or the manner in which, or the conditions under which the OWNER may enter into contract, shall be controlling, and shall be considered as part of this contract, to the same effect as though embodied herein. 3.16 ASSIGNMENT AND SUBLETTING. The CONTRACTOR further agrees that he will retain personal control and will give his personal attention to the fulfillment of this contract and that he will not assign by Power of Attorney, or otherwise, or sublet said contract without the written consent of the ENGINEER, and that no part or feature of the work will be sublet to anyone objectionable to the ENGINEER or the OWNER. The CONTRACTOR further agrees that the subletting of any portion or feature of the work, or materials required in the performance of this contract, shall not relieve the CONTRACTOR from his full obligations to the OWNER, as provided by this Agreement. 3.17 INDEMNIFICATION. The CONTRACTOR shall defend, indemnify and hold harmless the OWNER and the ENGINEER and their resoective officers, agents and employees, from and against all damages, claims, losses, demands, suits, judgments and costs, including reasonable attorneys' fees and expenses, arising out of or resulting from the performance of the work, provided that any such damages, claim, loss, demand, suit, judgment, cost or expense: (1) Is attributable to bodily injury, sickness, disease or death or to injury to or destruction of tangible property (other than the work itself) including the loss of use resulting therefrom; and, G-7 e b)' Texis ~ct,on. A.~E 1971 (2) Is caused in whole or in part by any negligent act or omission of the Contractor, any Subcontractor, anyone directly or indirectly employed by any one of them or anyone for whose acts any of them may be liable, regardless of whether or not it is caused in part by a party indemnified hereunder. The obligation of the CONTRACTOR under this Paragraph shall not extend to the liability of the ENGINEER, his agents or employees arising out of the preparation or approval of maps, drawings, reports, surveys, Change Orders, designs or specifications, or the giving of or the failure to give directions or instructions by the ENGINEER, his agents or employees, provided such giving or failure to give is the primary cause of the injury or damage. 3.18 INSURANCE. The CONTRACTOR at his own expense shall purchase, maintain and keep in force such insurance as will protect him from claims set forth below which may arise out of or result from the CONTRACTOR'S operations under the Contract, whether such operations be by himself or by any Subcontractor or by anyone directly or indirectly employed by any of them, or by anyone for whose acts any of them may be liable: (1) Workmen's ~:ompensation claims, disability benefits and other similar employee benefit acts; (2) Claims for damages because of bodily injury, occupational sickness or disease, or death of his employees, and claims insured by usual bodily injury liability coverages; (3) Claims for damages because of bodily injury, sickness or disease, or death of any person other than his employees, and claims insured by usual bodily injury liability coverages; and (4) Claims for damages because of injury to or destruction of tangible property, including loss of use resulting therefrom. 3.18.1 CERTIFICATE OF INSURANCE. Before commencing any of the work, CONTRAC- TOR shall file with the OWNER valid Certificates of Insurance acceptable to the OWNER and the ENGINEER. Such Certificates shall contain a provision that coverages afforded under the policies will not be cancelled until at least fifteen days' prior written notice has been given to the OWNER. The CONTRACTOR shall also file with the OWNER valid Certificates of Insurance covering all sub-contractors. ~,. PROSECUTION .~ND PROGRESS 4.01 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 the time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications, and within the time of completion designated in the Proposal: provided, also, that when the OWNER is having other work done, either by contract or by his own force, the ENGINEER may direct the time and manner of constructing the work done under this contract, so that conflict will be avoided and the construction of the various works being done for the OWNER shall be harmonized. The CONTRACTOR shall submit, at such times as may reasonably be requested by the ENGINEER, schedules which shall show the order in which the CONTRACTOR proposes to carry on the work, with dates at which the CONTRACTOR will start the several parts of the work, and estimated dates of completion of the several parts. G-8 ~ b, ~- ........... ~ ..... 4.02 EXTENSION OF TIME. Should the CONTRACTOR be delayed in the completion of the work by any act or neglect of the OWNER or ENGINEER, or of any employee of either, or by other contractors employed by the OWNER, or by changes ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoidable cause or causes beyond the CONTRACTOR'S control, or by any cause which the ENGINEER shall decide justifies the delay, then an extension of time shall be allowed for completing the work, sufficient to compensate for the delay, the amount of the extension to be determined by the ENGINEER, provided, however, that the CONTRACTOR shall give the ENGINEER prompt notice in writing of the cause of such delay. 4.03 HINDRANCES AND DELAYS. No claims shall be made by the CONTRACTOR for damages resulting from hindrances or delays from any cause (except where the work is stopped by order of the O~,~,.~ER) during the progress of any portion of the work embraced in this contract. In case said work shall be stopped by the act of the OWNER, then such expense as in the judgment of the ENGINEER is caused by such stoppage of said work shall be paid by the OWNER to the CONTRACTOR. 5. MEASUREMENT AND PAYMENT 5.01 QUANTITIES AND MEASUREMENTS. No extra or customary measurements of any kind will be allowed, but the actual measured and.-'or computed length, area, solid contents, number and weight only shall be considered, unless otherwise specifically provided. 5.02 ESTIMATED QUANTITIES. This agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and the material furnished. Where payment is based on the unit price method, the CONTRACTOR agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contemplated and contained in the proposal; provided, however, that in case the actual quantity of any major item should become as much as 20% more than, or 20%. less than the estimated or contemplated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a revised consideration upon the portion of the work above or below 20~ of the estimated quantity. A "Major Item" shall be construed to be any individual bid item incurred in the proposal that has a total cost equal to or greater than five (5) per cent of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices. Any revised consideration is to be determined by agreement between the parties, otherwise by the terms of this Agreement, as provided under "Extra Work." 5.03 PRICE OF WORK. In consideration of the furnishing of all the necessary labor, equipment and material, and the completion of all work by the CONTRACTOR, and on the completion of all work and of the delivery of all material embraced in this Contract in full conformity with the specifications and stipulations herein contained, the OWNER agrees to pay the CONTRACTOR the prices set forth in the Proposal hereto attached, which has been made a part of this contract. The CONTRACTOR hereby agrees to receive such prices in full for furnishing all material and all labor required for the aforesaid work, also for all expense incurred by him, and for well and truly performing the same and the whole thereof in the manner and according to this Agreement. G-9 o b:. Tex~ !~¢uon A$CE 1971 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/.he 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 10 per cent of the amount thereof. which 10 per cent shall be retained until final payment, and further less all previous payments and all further sums that may ~oe retained by tile 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 tile 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!!v 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 tile work, the CONTRACTOR shall be entitled to such extra compensation, or extension of time, or both, as the ENGINEER may determine. The CONTRACTOR shall notify the ENGINEER when, in the CONTRACTOR'S opinion, the contract is "substantially completed" and when so notifying the ENGINEER, the CONTRAC- TOR shall furnish to the ENGINEER in writing a detailed list of unfinished work. The ENGINEER will review the CONTRACTOR'S list of unfinished work 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 the CONTRACTOR his Certificate of Completion, and thereupon it shall be the duty of the OWNER within ten (10) days to issue a Certificate of Acceptance of the work to the CONTRACTOR or to advise the CONTRAC- TOR in writing of the reason for non-acceptance. 5.07 FINAL PAYMENT. Upon the issuance of the Certificate of Completion, the ENGI- NEER shall proceed to make final measurements and prepare final statement of the value of all work performed and materials furnished under the terms of the Agreement and shall certify same to the OWNER, who shall pay to the CONTRACTOR on or after the 30th day. and before t. he 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: G-10 (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 as 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 or' compensation to the CONTRACTOR for work either added or deleted by a Change Order or for which a claim for Extra Work is made shall be determined by one or more of the following methods: G-11 ~ by Tez= .c~t~on. A.~CE 1971 Method (A)--By agreed unit prices; or Method (B)--By agreed lump suni: or Method (C)--If neither Method (A) nor Method (B) be agreed upon before the Extra Work is commenced, then the CONTRACTOR shall be paid the "actual field cost" of the work, plus fifteen (15) percent. In the event said Extra Work be performed and paid for under Method (C), then the pro- visions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost to the CONTRACTOR df all workmen, such as foreman, timekeepers, mechanics and laborers, and materials, supplies, teams, trucks, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, including Social Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of premiums on Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property Damage and Workmen's Compensation, and 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- m~nt 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 (157k) per cent of the "actual field cost" to be paid the CONTRAC- TOR shall cover and compensate him for his profit, overhead, general superintendence and field office expense, and all other elements of cost and expense not embraced within the "actual field cost" as herein defined, save that where the CONTRACTOR'S Camp or Field Office must be maintained primarily on account of such Extra Work; then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for Extra Work of any kind will be allowed unless ordered in writing by the ENGINEER. In case any orders or instructions, either oral or written, appear to the CONTRAC- TOR to involve Extra Work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the ENGINEER for written order authorizing such Extra Work. Should a difference of opinion arise as to what does or does not constitute Extra Work, or as to the payment therefor, and the ENGINEER insists upon its performance, the CONTRACTOR shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as provided under Method (C). The CONTRACTOR will thereby preserve the right to submit the matter of payment to arbitration, as hereinbelow provided. 6.04 TIME OF FILING CLAIMS. It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the CONTRACTOR shall be in writing and filed with the ENGINEER within thirty (30) days after the ENGINEER has given any directions, order or instruction to which the CONTRACTOR desires to take exception. The ENGINEER shall reply within thirty (30) days to such xvritten ,~xceptions ny 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 :~ ........................... 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/or his Surety. Should the cost to complete the work exceed the contract price, and the CONTRACTOR and/or his Surety fail to pay the amount due the OWNER within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the CONTRACTOR and his Surety at the respective addresses designated in this contract, provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the CONTRACTOR and his Surety subject only to the duty of the OWNER to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the OWNER may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the CONTRACTOR and his Surety. Such sale may be made at either public or private sale, with or without notice, as the OWNER may elect. The OWNER shall release any machinery, equipment, tools,~ materials, or supplies, which remain on the work, and belong to persons other than the CONTRACTOR or his Surety, to their proper owners. The books on all operations provided herein shall be 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 the attached proposal where unit price~ 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 OV~ER under the terms of this A~reement and shall certifv 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. by the two arbiters so selected; or if the arbiters fail to select a third within ten (10) days, he shall be chosen by a District Judge serving the County in which the major portion of the project is located, unless otherwise specified. Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of the ENGINEER shall be final and binding on him. Should the other party fail to choose an arbiter within ten (10) days, the ENGINEER shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take ex parte proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any 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.

In case the CONTRACTOR should abandon and fail or refuse to resume work within ten (10) days after written notification from the OWNER, or the ENGINEER, or if the CONTRACTOR fails to comply with the orders of the ENGINEER, when such orders are consistent ~with the Contract Documents, then, and in that case, where 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 O~,~,~ER 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 OV~ER may thereupon employ such force of men and use such machinery, equipment, tools, materials and supplies as said OWNER may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said CONTRACTOR, and expense so charged shall be deducted and paid by the OWNER out of such moneys as may be due, or that may thereafter at any time become due to the 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 excess to the O'~,~ER: or 7.01.2 The OV~ER 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.

General Excavation shall include the removal of any stumps, debris and other obstacles that may obstruct the con- struction of the work and the excavation and removal of all earth, rock or other materials to the extent necessary to construct all the work shown on the plans. The excavation shall conform to the dimensions and elevations indicated on the drawings for each structure. Excavation shall extend a sufficient distance from walls to allow for placing and removal of forms, installation of piping, and for inspection. Concrete for footings shall be deposited directly against excavated surfaces. Excavation for foundations and footings shall not be plowed, scraped, or machine-dug closer than 3 inches to the finished subgrade elevation. The last layer of excavation shall be removed by hand labor to the exact lines and grades just before placing the work. B. Shoring and Sheeting Such shoring and sheeting as may be required during excavation shall be installed to protect the banks, adjacent structures, and utilities. TS2-1 C. Excess Material Excess material from excavation, not required for fill or backfill, Shall be deposited, spread and graded where in- dicated on the drawings or as directed by the Engineer. When required by the Engineer, any top soil over excavated areas shall be separately piled at a convenient place and later used as a top dressing for all new berms and embank- ments to a minimum depth of four (4) inches. D. Benchmarks and Stakes The Contractor shall carefully maintain and protect all benchmarks and reference stakes and if disturbed or damaged, replace as directed by the Engineer at the expense of the Contractor. E. Protection of Facilities Existing utility lines (either overhead or underground), sidewalks, or pavement designated on the drawings, shown to the Contractor or mentioned in the specifications shall be kept free of damage by the Contractor's operations. If damaged, any utilities, sidewalks or pavements shall be restored at the Contractor's expense. If any utility is not known as above in time to prevent damage and if inadvertently damaged during operations, the Contractor shall notify the Engineer and the Owner of said utility at once so that emergency repair may be made at the Contractor's expense. F. Drainage in the Vicinity of StructuYes The Contractor shall control the grading in the vicinity of all structures so that the surface of the ground will be properly sloped or diked to prevent water from running into the excavated areas. Any water which accumulates in the excavation shall be promptly removed by the Contractor. G. Grubbing All roots, stumps, and other debris shal) be removed from the site. All depressions resulting from the removal of stumps, roots and debris shall be filled with suitable materials and compacted to make the surface conform to the surrounding ground. H. Dispos.al.._of Cleared or Grubbed Material All timber, logs, stumps, roots, brush and other refuse from clearing and grubbing operations shall become the property of the Contractor and shall be removed from the site. TS2-2 Whenever, through neglect of the Contractor, t ekcavation is carried beyond or below the lines and grades giv6'n by the Engineer, or shown on the plans, all such excavated space shall be refilled with such material and in such a manner as may be directed by the Engineer, in order to insure the stability of the various structures. Beneath all structures, space excavated without authority shall be refilled by the Contractor, at his own expense, with 2,000 p.s.i, concrete, gravel backfill or selected fill materials, as directed by the Engineer. 2.05 FOUNDATI ON A. From a foundation standpoint, all supporting soils under slabs or footings may be considered moderately expansive. !n order to minimize future swell, in-place moisture content shall be maintained during excavation and construction operations. Accordingly, the Contractor shall place a 2,000 p.s.i, concrete seal of two (2) inches thickness over the finished subgrade. The placement of the concrete seal shall not exceed six (6) hours after completion of the finished subgrade. Material and labor required for this sub- grade protection will not be measured or paid for separately. B. After completion of the excavation and prior to placing the reinforcing steel and/or concrete, the Contractor shall notify the Engineer who will inspect the excavation to it insure that suitable foundations have been reached. Approval of the excavations shall be obtained at the time of their completion and again immediately prior to placing of rein- forcing steel and/or concrete for footings, piers and slabs. 2.06 PROTECTIO~N AGAINST LOSS OF MOISTURE Soils are susceptible to volume change due to variations in moisture content. Therefore, all excavation shall be pro- tected against excessive loss of moisture during construc- tion. The Contractor shall make every effort to place concrete upon excavated areas within a minimum amount of time after excavation has been finished. It shall be the responsibility of the Contractor to keep moisture content of the subgrade at the original value by any method approved by the Engineer. In any areas where sand fill is used under slabs, this sand shall be kept moist to keep moisture from escaping the subgrade. If for any reason the subgrade is allowed to dry out, the Contractor shall inject water into the subgrade to raise moisture content to the satisfaction of the Engineer. By the same token, excessive moisture will not be allowed in the excavation at the time of placing concrete. Tests for moisture content have been made at locations of the borings shown on the plans and records of the tests are available for information at the City Hall or from the Eng i neer. TS2-3 2.07. FILLING .,'..j A. Where concrete slabs are placed on earth, all organic or othe~ undesirable material, as determined by the Engineer shall be removed. Where fill is required to raise the subgrade for concrete slabs to the elevation as indicated on the drawings, such fill shall consist of suitable earth as approved by the Engineer. B. The approved materials shall be placed in successive horizontal layers of loose material not more than 6 inches thick where compaction is by rollers or vibration and 4 inches thick where mechanical tamping is required. For cohesive soils each layer shall be wetted or dried by aeration to a moisture content of 3 to 5 per cent above optimum beneath all floor slabs. If uniformly graded sands are used, the fill shall be placed completely dry or fully saturated to prevent bulking. Well graded gravel shall be placed at the optimum moisture content. 2.08 BACKF...ILLING AROUND STRUCTURES A. After completion of foundation footings, walls and other con- struction below the elevation of the final grades, and prior to backfilling, all forms shall be removed and the excavation cleaned of all trash and debris. Material for backfill shall be obtained from the excavation and shall be subject to the approval of the Engineer. Backfill shall be placed in hori- zontal layers not to exceed 6 inches in thickness. Each layer shall be compacted with proper moisture content and with such equipment as may be required to obtain a density equal to or greater than ninety per cent (90%) of the maximum dry density as determined by the "Modified Proctor Compaction Test" Trucks or heavy equipment for depositing backfill or for compacting shall not be used with 5 feet of building walls, piers, or other facilities which may be damaged by their weight or operation. Methods of compaction shall be subject to approval of Engineer. Care must be taken not to damage the structure. B. Consolidation of backfill may be accomplished by flooding, or .. jetting, with the Engineer's approval, in lieu of tamping as specified above, provided it is done in such a manner as to secure uniform consolidation throughout the backfill. C. Backfilling shall begin only with approval of the Engineer, and in no case shall backfill be placed against concrete or masonry walls 4 feet and over in height that are unsupported on their inside face until these walls have been in place for seven (7) days of good curing weather. TS2-4 t ! 2.09 GRANULAR FILL UNDER SLAB A. Granular fill shall be provided under slabs as shown. Granu- lar fill shall Consist of free flowing materials such as sand, gravel, or mixture of sand and gravel, free from lumps, large stone, clay and organic materials. B. The voids in the top surface of the granular fill shall be filled with sand, crushed stone screenings, crushed gravel screenings, or concrete as indicated on the drawings to provide a smooth even surface. Fill shall be leveled and tamped as directed by the Engineer. 2.10 FILL AROUND DRAIN LINES Under slab and perimeter drains shall be backfilled with gravel conforming to ASTM C33, graded 3/4" to #4. 2.11 CONSTRUCTION OF EMBANKMENTS AND FILLS -A. Before fill is started, scarify to a minimum depth of 6 inches all proposed embankment and fill areas under proposed roads, parking lots, or streets. In areas where ground sur- face is steeper than one vertical to four horizontal, plow surface in a manner to bench and break up surface so that fill material will bind with existing surface. B. Use fill materials reasonably free of roots, organic matter, trash or frozen material. Remove all soft and yielding material which will not compact readily and replace with suitable material. C. It has been assumed that minor areas of materials unsuitable for fill, and areas unsuitable to fill on, will be encoun- tered in the normal course of work. Should areas of un- suitable material be encountered totaling 200 cubic yards or less, it shall be removed and replaced with suitable material at the Contractor's expense. If unsuitable material is encountered in excess of 200 cubic yards, it shall be re- moved and replaced with suitable material and that portion in excess of 200 cubic yards will be paid for as "Extra Work". D. Allow material containing an excess of water to dry to a moisture content which will allow acceptable compaction. Material excessively wet or dry and not at optimum moisture content is not considered unsuitable. E. Construct embankments and fills at locations and to lines of grade indicated. Completed fill shall correspond to shape of typical cross section or contour indicated regard- less of method used to show shape, size, and extent of line and grade of completed work. TS2-5 F. Provide fill material which is free from..~roots, organic matter, trash, frozen material, and stones having a maximum dimension greater than 6 inches. Insure that stones larger than 4 inches are not placed in upper 6 inches of fill or embankment. Place material in maximum 8 inch loose thickness. Place layers horizontally and compact each layer prior to placing additional fill. G. Compact by sheapsfoot or pneumatic rollers, vibrators or other suitable equipment. Control moisture for each layer as necessary to meet requirements of compaction. Do not place materials in embankments or fills which exceeds optimum moisture content by 3 percent or is 3 percent below optimum moisture content. H. Compact fills and embankments accordingly: (1) Under roadways and parking areas and extending 1 foot beyond proposed curb line measured perpendicular from centerline, compact to density not less than 95 percent maximum dry density as determined by the Modified Proctor Method and measured by ASTM 01557. (2) Under proposed building and structure sites, compact to density as otherwise specified herein or on the construction drawings. (3) For other embankments and fills not listed, compact to not less than 90 percent of maximum dry density as determined by the Modified Proctor Method, ASTM 01557. (4) Owner will hire an independent soils laboratory to con- duct in place moisture-density tests to insure that all work complies with this Specification. Any compacted material not meeting specified compaction requirements shall be corrected and/or recompacted and retested at Contractor's expense. I. Borrow. Provide, at no extra cost, necessary amount of approved fill compacted to density indicated. Borrow or fill cannot be obtained on site except when specially permitted by Engineer. J.

TS1 5-5 TECHNICAL SPECIFICATION NO. 25 CONSTRUCTION JOINTS & WATERSTOPS 25.01 GENERAL This section covers construction joints, expansion joints and the placing of waterstops where such are indicated on the plans. Construction joints shall be of the type indicated on the drawings and shall be located as shown on the plans unless otherwise approved by the ENGINEER. Permission will be granted to eliminate a construction joint providing the work can be scheduled so as to make a continuous pour without the need of the joint whose elimination is requested. 25.02 POLYVINYL PLASTIC WATERSTOP Waterstops shall be installed in construction joints as required by the plans. All waterstops shall be continuous throughout their length. The waterstops shall be heavy duty Polyvinyl Waterstop as manufactured by Servicised Products Corporation, Chicago, Illinois, or an approved equal of the same type and material and approximately equal in dimensions and weight but not necessarily of exactly the same shape. Waterstops shall be of the size and type designated on the plans. The waterstop shall be extruded from polyvinyl chloride resin plastic having the following properties: Tensile Strength = 1,700 p.s.i. Ultimate Elongation : 250% Brittleness Temp. (ASTM D746-57T) : -25°F. All waterstops shall be installed so that one-half its width will be embedded on one side of the joint and one-half on the other. The CONTRACTOR shall employ a method of holding the waterstop in position for the first pour that is satisfactory to the ENGINEER. The method selected must insure that the waterstop will be held securely in true vertical position and in straight alignment in the joint. Care shall be exercised to insure that the waterstop is completely encompassed in good mortar. TS25-1 25.03 JOINTS IN WATERSTOPS All waterstops shall be continuous and so joined at all points of contact in the same plane, or at intersections with water- stops in different planes, as to form a complete barrier to the passage of water through any construction, contraction or expan- sion joint. Joints in the waterstops, whether made for the purpose of con- tinuity in a straight strip or for the purpose of securing a watertight junction between strips in different planes, shall be made by heat welding as hereinafter specified. Joints in P.V.C. waterstops shall be made by heating the two surfaces to be joined until the material has softened to the point ~ere it is just short of being fluid and then bringing the two softened surfaces together with a slight rubbing motion followed by firmly pressing them together so that a solid and tight bond is made. The joints in strips of waterstop made in the above manner shall be such that the entire cross section of the joint shall be dense, homogenous and free of all porosity. All finished joints shall have a tensile strength of not less than 75 percent of the material of the strip as extruded. The heating of the surfaces to be joined shall be done by means of an electric hot plate designed for the specific purpose and controlled by means of a voltage regulator. The hot plate used shall be that manufactured by the Ogden Manu- facturing Company of Chicago, Illinois, or approved equal. It shall be rated at 1,O00 watts for use with ll5-volt electric current. The size of the plate shall be approximately 4-inch by lO-inch and shall be such that both sides of the plate can be used simultaneously. The voltage regulator to be used in conjunction with the above described hot plate shall be a Type 5003 "Adjust-A-Volt" rated at 7.5 amps, ll5-volt input and O-135-volt output, as manufac- tured by the Standard Electric Products Company. In use, the heat of the hot plate shall be so regulated as to prevent too rapid melting and accompanying charring of the waterstop material. The use of makeshift hot plates will not be permitted nor will other means of heating the strips to be joined be allowed except in a case of emergency, as determined by the ENGINEER. TS25-2 The CONTRACTOR shall provide such jigs as will assist in making the joints in a proper and workmanlike manner and in holding the strips so that the alignment of joined strips is correct and angles are true to those required. As may be required, the CONTRACTOR shall train a skilled workman in the use of the equipment and the making of joints in advance of need; and during construction all joints shall be made by a workman with such training. Prior to embedment all joints in the waterstop strips will be carefully inspected by the ENGINEER and any found defective shall be remedied under his supervision and without delay. 25.04 PROTECTION OF WATERSTOP BETWEEN POURS The CONTP~ACTOR shall take such steps as are necessary to protect exposed waterstops in the interim period between concrete pours. The watertightness of the structure will depend upon the care and workmanship employed in making construction joints and securing good and full mortar embedment on all sides of the waterstops. Accordingly, this phase of the work will be subject to rigid inspection. 26.05 EXPANSION JOINTS Expansion joints of the size and type shown on the plans, or specified herein, shall be placed in concrete pavement or struc- ture as shown on the plans. a. Performed Asphalt Fiber Joint Material Asphalt fiber sheet filler shall consist of preformed strips of inert material impregnated with asphalt.

Hot Poured Rubberized Tar Joint Sealer Joint sealer shall be used where indicated on the plans and on the outside of any surface exposed to the elements where a construction joint has been formed in the concrete. The joint sealer shall be P, AM-NEK as manufactured by K. T. Snyder Co., 4101 San Jacinto, P. O. Box 8188, Houston, Texas, or approved equal. The joint shall be primed and prepared so the material applied shall be in strict accordance to the manufacturers specifications and subject to the approval of the ENGINEER. TS25-4 TECHNICAL SPECIFICATIONS NO. 30 TESTING AND STERILIZATION 30.01 GENERAL The work covered by this technical specification consists of furnishing all labor, tools, materials and equipment in per- forming all operations required by the Engineer in testing new reservoirs, basins and plant piping systems for leakage and in the sterilization of these units. 30.02 HYDROSTATIC TESTING a. Basins and Reservoirs Upon completion of the new unit and after all miscellaneous items of equipment have been installed in the new unit, all debris and waste materials shall be removed and all interior surfaces shall be thoroughly washed and flushed with clean water and sterilized in accordance with Section 30.03 of this specification. The unit shall then be filled with clean water to a depth equal to the proposed maximum water level or to a depth designated by the Engineer. The water level shall be maintained at the prescribed level for a period of at least 24 hours prior to beginning any leakage tests to allow for any absorption of the water by the unit. The water level shall be measured and no additional water shall be added to or taken from the unit for a period of 72 hours and the water level in the tank shall be observed and measured at 12 hour intervals during this period. At the end of this period the water level shall again be measured and the amount of water lost shall be computed. Should the quantity of water lost exceed a rate of 2,000 gallons per day per million gallons of unit capacity, the Contractor shall drain the unit, locate and repair the source of leakage, and repeat the testing procedure until the unit meets the approval of the Engineer. All costs involved in locating and repairing any leaks, testing and retesting the unit shall be at the expense of the Contractor. All known leaks shall be stopped, regardless of this test equipment. b. Plant Piping After the piping, and all supports, hangers, permanent braces and thrust blocks have been installed, the piping shall be tested in such sections as are convenient for the Contractor and approved by the Engineer. The Contractor shall inspect and test each system in the presence of the Engineer. The Contractor shall furnish all labor, materials, TS30-1 tools and equipment necessary to bulkhead and seal off the line for testing, fill it with water, raise the filled line to test pressure and measure the amount of leakage over the test period. The pipe line shall be tested at a hydrostatic pressure, equal to not less than the maximum water working pressure for which the pipe is designed, maintained for a period of not less than four (4) hours. A test for the determination of amount of leakage shall be run at the same time. If the tests indicate a leakage in excess of a rate equal to fifty (50) gallons per inch of internal pipe diameter per mile of pipe line per twenty-four (24) hours, the Contractor will be required to find and eliminate the leak. All known leaks shall be stopped, regardless of this test requirement. The cost of testing, finding and repairing the leaks and retesting, if necessary, shall be at the expense of the Contractor. The water required to fill the lines will be furnished by the Owner, without charge to the Contractor. 30.03 STERILIZATION a. Basins and Reservoirs All exposed interior surfaces shall be sprayed with a so-'~Tution having a strength of 200 p.p.m, available chlorine. This solution shall be sprayed over the inner surfaces of the empty structure by using fruit-tree spraying equipment. The surfaces disinfected should remain in contact with the strong solution at least one (1) hour before the structure is filled with water. The tank shall then be filled with good, clean water and samples for bacteriological tests shall be taken in order to determine if the sterilization has been successful. b. Piping Prior to sterilizing, each valved section of the new pipe line shall be pressure tested and flushed with clean water from a source approved by the Engineer, to remove all visible evidence Of dust, soil, and fine debris which may have entered the line during construction and testing. The water required to flush and sterilize the lines, without un- necessary waste, will be furnished by the Owner, without charge to the Contractor. Chlorine shall be used to sterilize the pipe line by the following method: TS30-2 The amount of chlorine applied shall be such as to provide a dosage of not less than fifty (50) parts per million. The chlorinating material shall be introduced to the water lines and distribution system in a manner approved by the Engineer. After a contact period of not less than eight (8) hours, the system shall be flushed with clean water until the residual chlorine content is not greater than 0.2 parts per million. All valves in the lines being sterilized shall be opened and closed several times during the contact period. Samples shall be collected from various taps and fixtures throughout the plant during the introduction of the chlorine to assure uniform distribution.

Short pipe sections and angle adaptors will be used to make necessary line and grade changes in the field. All pipe and fittings shall be laid on specified bedding so as to be uniformly supported along its entire length. No "blocking up" of pipe or joints will be permitted. Bell holes to allow making the exterior joint shall be provided. The pipe shall be kept clean during the laying operation and free of all sticks, dirt and trash, and at the close of each working day the open end of the pipe shall be effectively sealed against the entrance of all objects, and especially water. Where indicated on the contract drawings or where, in the opinion of the Engineer, it is necessary, the pipe or fittings shall be blocked with concrete. Each section of pipe shall be tightly fitted together and care- fully installed to true line and grade. Prior to laying each joint of pipe the bell and spigot shall be thoroughly cleaned by brushing and wiping. The rubber gasket and the inside surface of the bell shall be lubricated with an approved lubricant (vegetable compound soap) which will facilitate telescoping of the joint. The rubber gasket will be snapped into the spigot ring groove to equalize circumferential distribution of the gasket. After the spigot is forced into the bell of the adjacent pipe, the inside recess between the ends of the pipe shall have a maximum opening of l" for pipe 21" and smaller and l-l/4" for pipe 24" and larger, and a minimum opening of 1/4". Interior joints on pipe 18" and smaller shall be made prior to placing the pipe together by buttering the bell end with mortar. After the joint is engaged, the inside joint is smoothed and cleaned with a swab. Interior joints on pipe 20" and larger shall be made after jointing the pipe by filling the annular space with mortar placed and smoothed by hand. Mortar for inside joints shall be one part Portland cement, and two parts clean sand. The exterior joint shall be made by placing a joint wrapper around the pipe. The joint wrapper shall be 7" minimum width and be hemmed on each side. It shall encircle the pipe, leaving an opening at the top to allow placing mortar and be fastened to the pipe with metal strapping. TS34-3 The liquid grout used for pouring the joint shall consist of one part Portland cement, and two parts clean sand. The joint shall be filled from one side in one continuous operation until the grout has flowed entirely around the pipe. During the fillin.q of the joint it shall be rodded to settle the grout. All exposed steel on fittings or specials shall be protected by a l" coating of Portland cement mortar. After placing, the mortar will be covered with damp earth or burlap to prevent rapid drying out. 34.05 PROTECTION OF PIPELINE Tight fitting stoppers or bulkheads shall be securely placed in all openings and in the end of the line when construction is stopped temporarily and at the end of each day's work. It shall be the responsibility of the Contractor to deliver to the Owner a pipeline which is c)ean throughout its entire length. 34.06 CONCRETE BLOCKING Class 2000 concrete shall be placed, as directed by the Engineer, for blocking at each change in direction of the pipeline in a manner which will substantially brace the pipe against undis- turbed trench walls.

The Contractor shall furnish all labor, materials, tools and equipment required to bulkhead and seal off the line for testing, fill it with water, raise the filled line to test pressure and measure both pressure and leakage over the specified test period. The entire length of the installed line shall be field tested for water tightness in the following manner. The section of the pipeline to be tested shall be filled with water and allowed to stand for such time as is required for the cement lining of the pipe to absorb such water as it TS34-4 will and for the escape of all air from the line. During the filling of the pipe, care shall be exercised to see that all air vents are open, and all bulkheads, valves, manholes, connections, etc., in the section undergoing test shall be carefully examined for leakage. All known leaks shall be stopped, regardless of these test require- ments. The test shall consist of raising and holding the hydro- static pressure in the test action to 150 P.S.I. pressure for which the pipe was designed, unless otherwise noted in the special conditions. Such test pressure shall be main- tained for a period of four {4) hours, during which time the water pumped into the line to maintain the test pres- sure shall be accurately measured in a manner satisfactory to the Engineer. A test for the determination of amount of leakage shall be run subsequent to the hydrostatic test. The test for the leakage shall be run for a duration of two (2) hours at the same pressure as for the hydrostatic tests. The amount of leakage shall not exceed a rate equal to l0 gallons per inch of internal pipe diameter per mile per 24 hours for pipe in 40-foot lengths. In the event any section of the line tested fails to meet the above specified requirements for water tightness, the cause of the excessive leakage shall be determined and remedied to the satisfaction of the Engineer, at the expense of the Contractor. The pipeline shall then be retested to comply with the specified hydrostatic and leakage tests. (b) Sterilization - Prior to sterilizing, each valve section of the new pipe shall be pressure tested and flushed with clean water furnished by the Owner to remove all apparent evidence of dust, soil, and fine debris which may have entered the line during construction and testing. The water required to flush and sterilize the lines, without unnecessary waste, will be furnished by the Owner, without charge to the Con- tractor, unless otherwise specified herein. Chlorine shall be used to sterilize the pipeline by the following method: The amount of chlorine applied shall be such as to provide a dosage of not less than fifty (50) parts per million. The chlorinating material shall be introduced to the new water lines in a manner approved by the Engineer. After a contact period of not less than eight (8) hours, the system shall be flushed with clean water until the residual chlorine content is not greater than 0.2 parts per million. All valves in the lines being sterilized shall be opened and closed several times during the contact per iod. TS34-5 Unless otherwise provided for in the Proposal, the cost of furnishing the chlorine, labor, tools, equipment, bacterio- logical tests and tests of chlorine content will be at the expense of the Contractor. No water mains shall be placed in service until water samples have been taken by the Contractor and a satisfactory test report has been received from an approved laboratory. 34.09 AIR VALVE INSTALLATIONS Air valves shall be installed at the locations shown in the plans. The lump sum amount in the Proposal shall include furnishing and installing all required material, apparatus and incidentals performing all operations necessary for the instal- lation of an air valve in accordance with the detail shown on the plans.

Metal rails may be necessary within the encasement pipe to pro- vide straight alignment and grade. Permanent jacks or wedges shall be used to prevent floating. If a carrier pipe joint is to be located within the tunnel, the encasement pipe shall be large enough to provide a minimum of 15-inches clear space above the carrier pipe for access to place cement mortar protection around the joint. If access space is not provided, the carrier pipe joints shall be welded and mortar protection applied as specified above before the carrier pipe is placed in the tunnel. The cement mortar shall be allowed to harden sufficiently to avoid dislodgement during installation. If time is of the essence, quick-setting compound such as Embeco, or approved equal, may be used. TS34-6 In open cut construction with encasement pipe of insufficient size to permit access to exterior joints of carrier pipe, an opening shall be provided in encasement pipe of each carrier pipe joint. The opening shall be closed in an approved manner after protecting the carrier pipe joint with cement mortar. 34.12 LINES AND GRADES Under Section lO of the General Conditions of Agreement after the first sentence, "unless otherwise expressly provided for in the Specifications, the Owner will furnish to the Contractor all surveys necessary for the execution of the work", add the follow- ing paragraphs: "The Engineer will furnish stakes and elevations to enable the Contractor to set his batter boards, string lines and grade rod for constructing the treated water transmission main and related appurtenances. The furnishing of the stakes and elevations does not relieve the Contractor of the responsibility of checking to insure that the mains, man- holes and other related appurtenances are constructed to the lines and grades shown on the plans. The Contractor shall take every precaution to prevent the removal of disturbance of the construction stakes estab- lished by the Engineer for this project. ~hould any of the stakes be removed or otherwise disturbed through care- lessness of the Contractor, the stakes will be replaced at the expense of the Contractor. It may be found necessary for the Engineer and Owner to make whatever revisions necessary in alignment, grades and materials where during construction there is found to be existing conditions which would warrant a more practical and economical installation. The Contractor will be paid only for the materials actually installed as listed in the Proposal and any other compensation for the revision will not be considered." 34.13 MEASUREMENT AND BASIS OF PAYMENT Payment for the piping, valves, fittings, fire hydrants, concrete blocking, base pads, complete in place, and all other work necessary and incidental to the installation thereof, all, in accordance with the plans and the provisions of these Technical Specifications No. TS34, shall be included in the lump sum bid as provided in the Proposal.
