Responsibilities of the Engineer and the Contractor 2.01 Owner - Engineer Relationship The Engineer will be the Owner'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 instruc- tions 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 any detailed, exhaustive, 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, sequences, 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 Contrac- tor, any subcontractor or any of the Contractor's or subcontractor's agents, servants or employees or any other person, firm or corporation performing 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 Contractor constitutes a representation to the Owner of Engineer's professional GC-4 1 1 •;l 1 1 1 1 1 1 1 1 14- 1 _. 1 1 1 1 1 1 1 1 1 judgment that the work has progressed to the point indicated to the best of his knowledge, information and belief, but such approval of an application for payment to Contractor shall not be deemed as a repre- sentation 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, which shall not be construed to be less than ten days, appeal to arbitration may be taken as if his deci- sion 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 ac- cordance 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 English- speaking superintendent and any necessary assistants to supervise and direct the work. 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. 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 employees and other persons, as well as for the protection of the safety of the improvements being erected and the property of himself or any other person, as a result of his operations hereunder. Engineering construction drawings and specifications as well as any additional information concerning the work to be performed passing from or through the Engineer shall not be interpreted as requiring or allowing Contractor to deviate from the plans and specifications, the intent of such drawings, specifications and any other such instruc- tions being to define with specificity the agreement of the parties as to the work the Contractor is to perform. Contractor shall' be fully and completely liable, at his own expense, for design, construction, installation and use, or non -use, of all items and methods incident to performance of the contract, and for all loss, damage or injury incident thereto, either to person or property, including, without limitation, the adequacy of all temporary supports, shoring, bracing, scaffolding, machinery or equipment, safety precautions or devices, and similar items or devices used by him during construction. Any review of work in process, or any visit or observation during construction, or any clarification of plans and specifications, by the Engineer or Owner, or any agent, employee, or representative of either of them, whether through personal observation on the project site or by means of approval of shop draw- ., GC-5 ings 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 per- formed, 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 com- pleted 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 not limited to 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 Contractor'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 Contractor 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 encountered, 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 in 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. No illegal alien may be employed by any Contractor for work on this project, and a penalty of $500.00 per day will be assessed for each day and for each illegal alien who works for the Contractor at this project. 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 ob- servation, shall be constructed and maintained by the Contractor in such manner and at such points as shall be approved by the Engineer, and their use shall be strictly enforced. 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 set- ting drawings and schedules required for the work of the various trades, and the Engineer shall pass upon them with reasonable promptness, making desired corrections. The Contractor shall make any cor- rections required by the Engineer, file with him two corrected copies and furnish such other copies as may be needed. The Engineer's approval of such drawings or schedules shall not relieve the Contractor from responsibility for deviations from drawings or specifications, unless he has in writing called the Engineer's attention to such deviations at the time of submission, nor shall it relieve him from responsi- bility for errors of any sort in shop drawings or schedules. It shall be the Contractor's responsibility to fully and completely review all shop drawings to ascertain their effect on his ability to perform the required contract work in accordance with the plans and specifications and within the contract time. Such review by the Engineer shall be for the sole purpose of determining the sufficiency of said drawings GC -6 R...7.1.75 1 1 1 1 1 1 1 1 1 1 or schedules to result in finished improvements in conformity with the plans and specifications, and shall not relieve the Contractor of his duty as an independent contractor as previously set forth, it being expressly understood and agreed that the Engineer does not assume any duty to pass upon the propriety or adequacy of such drawings or schedules, or any means or methods reflected thereby, in rela- tion to the safety of either person or property during Contractor's performance hereunder. 2.13 Preliminary Approval The Engineer shall not have the power to waive the obligations of this contract for the furnishing by the Contractor of good material, and of his performing good work as herein described, and in full accordance with the plans and specifications. 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 Contractor, 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 plans and /or 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 work, should the Contractor proceed with such work without requesting prior inspection or approval 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 plans, specifications, or the intent thereof, the Contractor shall, after receipt of written notice thereof from the Engineer, forthwith remove such material and rebuild or otherwise remedy such work so that it shall be in full accordance with this contract. 2.15 Changes and Alterations The Contractor further agrees that the Owner may make such changes and alterations as the Owner may see fit, in the line, grade, form, dimensions, plans or materials for the work herein contemplated, or any part thereof, either before or after the beginning of the construction, without affecting the validity of this contract and the accompanying Performance and Payment Bonds. If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the basis for a claim for damages, or anticipated profits on the work that may be dispensed with, except as provided for unit price items under Section 5 "Measurement and Payment." If the amount of work is increased, and the work can fairly be classified under the specifications, such increase shall be paid for according to the quantity actually done and at the unit price,-if any, established for such work under this contract, except as provided for unit price items under Section 5 "Measurement and Payment "; otherwise, such additional work shall be paid for as provided under Extra Work. In case the Owner shall make such changes or alterations as shall make useless any work already done or material already furnished or used in said work, then the Owner shall recompense the Contractor for any material or labor so used, and for any actual loss occasioned by such change, due to actual expenses incurred in prepara- tion for the work as originally planned. 2.16 Inspectors The Engineer may provide one for more) field inspectors at the work site for the limited purpose of GC-7 observing the work in progress and reporting back to the Engineer on the extent, nature, manner and performance of the work so that the Engineer may more effectively perform his duties hereunder. Such inspectors may also communicate between Engineer and Contrator their respective reports; opinions, questions, answers and clarifications concerning the plans, specifications and work but shall be deemed the agent of the Contractor for all purposes in communicating such matters. Such inspector may confer with the Contractor or Contractor's superintendent concerning the prosecu- tion of the work and its conformity with the plans and specifications but shall never be, in whole or part, responsible for, charged with, nor shall he assume, any authority or responsibility for the means, methods or manner of completing the work or of the superintendence of the work or of the Contractor's employees. It is expressly understood and agreed that any such inspector is not authorized by the Engi- neer or Owner to independently act for either or answer on behalf of either, any inquiries of the Con- tractor concerning the plans, specifications or work. No inspector's opinion; advice; interpretation of the plans or specifications of this contract; apparent or express approval of the means, methods or manner of Contractor's performance of work in progress or completed; or discovery or failure to discover or object to defective work of materials shall release Contractor from his duty to complete all work in strict accordance with the plans and specifications or estop the Owner or Engineer from requiring that all work be fully and properly performed including, if necessary, removal of defective or otherwise unaccep- table work and the re-doing of such work. 3. 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 same con- stantly accessible on the work, with the latest revisions noted thereon. 3.02 Ownership of Drawings All drawings, specifications 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 there- fore 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 Contractor, except where such delays are specifically mentioned elsewhere in the Contract Documents. The Owner will attempt to coordinate the collateral work of utility GC-8 1 1 1 1 (i 1 1 1 9 1 1 1 ... 1 1 1 1) 1 1 1 1 1 1 F.4 1 1 1 1 1 companies regulated by City franchises, but the City shall not be responsible for delays or other damages to the Contractor which may result from their acts or omissions. 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 Docu- ments" shall govern. In the event that there is still any doubt as to the meaning and intent of any por- tion 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 mate- rials, 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. 3.08 Damages In the event the Contractor is damaged in the course of completion of the work by the act, neglect, omis- sion, mistake or default of the Owner or Engineer, 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.

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 Performance and 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 supply- ing labor and materials or furnishing him any equipment in the execution of the Contract, and it is agreed that this Contract 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 Owner, 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 and shall be licensed to write such bonds in the State of Texas. Unless otherwise specified, the cost of the premium for the performance and payment bonds shall be included in the Contractor's proposal. GC -9 3.12 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. 3.11 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 construc- tion; 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 regardless of whether or not it is caused in part by a party indemnified hereunder, but any such indemnity shall not apply to any claim of any kind arising solely out of the existence or character of the work. 3.13 Protection against Claims of Sub - contractors, Laborers, Materialmen and Fumishers of Machinery, Equipment and Supplies The Contractor agrees that he will indemnify and save the Owner 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 commis- sary, 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 to do so, 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 Contractor shall pay all royalties and license fees, and shall provide for the use of any design, device, material or process covered by letter 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 copy- right 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 Onwer; 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 the material or process specified or required by the Owner is an infringement, 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, ordi- nances, and regulations whether by the Contractor or his employees, except where such violations 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 neces- sary changes shall be adjusted as provided in the contract for changes in the work. If the Contractor GC -10 1 1 1 1 1 1 1 1 1 1 1 performs any work knowing it to be contrary to such laws, ordinances, rules and regulations, and with- out 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 con- tract, shall not relieve the Contractor from his full obligations to the Owner, as provided by this Agree- ment. 3.17 Indemnification The Contractor shall defend, indemnify and hold harmless the Owner and the Engineer and their respec- tive officers, agents and employees, from and against all damages, claims, losses, demands, suits, judg- ments 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 to any person including Contractor's employees and any Subcontractor's employees and any Sub-Subcontractor's employees or to injury to or destruction of tangible property including Contractor's property (other than the work itself) and the property of any Subcontractor or Sub - Subcontractor including the loss of use resulting therefrom; and, (2) Is caused in whole or in part by any intentional or negligent act or omission of the Contractor, any Sub-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 approval of maps, drawings, reports, surveys, Chahge 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 sole cause of the injury or damage. In any and all claims against the Owner or the Engineer or any of their agents or employees by any employee of the Contractor, any Subcontractor, any Sub-Subcontractor, anyone directly or indirectly employed by any of them or anyone for whose acts any of them may be liable, the indemnification obli- gation under Paragraph 3.17 shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for the Contractor or any Sub - Contractor or Sub - Subcontractor under workmen's compensation acts, disability benefit acts or other employee benefit acts. 3.18 Insurance The Contractor shall carry inurance as follows for the duration of this contract. A. Statutory Workmen's Compensation B. Comprehensive General Liability Insurance with minimum Bodily Injury limits of $300,000 for each occurrence including like coverage for acts and omissions of Subcontractors and contractual liability coverage. GC -11 C. Property Damage Insurance with minimum limits of $50,000 for each occurrence including like coverage for acts and omissions of Subcontractors and contractual liability coverage. D. Automobile Liability Insurance for all owned, non-owned, and hired vehicles with minimum limits for Bodily Injury of 5100,000 for each person and 8300,000 for each occurrence and Property Damage minimum limits of 850,000 for each occurrence. Contractor shall require sub- contractors to provide Automobile Liability Insurance with same minimum limits. The Contractor shall not commence work at the site under this contract until he has obtained all re- quired insurance and until such insurance has been approved by the Owner and Engineer. The Contrac- tor shall not allow any Subcontractors to commence work until all insurance required has been obtained and approved. Approval of the insurance by the Owner and Engineer shall not relieve or decrease the liability of the Contractor hereunder. The required insurance must be written by a company licensed to do business in Texas at the time the policy is issued. In addition, the company must be acceptable to the Owner and all insurance (other than workmen's compensation) shall be endorsed to include the Owner as an additional insured thereunder. The Contractor shall not cause any insurance to be cancelled nor permit any insurance to lapse. All in- surance certificates shall include a clause to the effect that the policy shall not be cancelled or reduced, restricted or limited until ten (10) days after the Owner has received written notice as evidenced by return receipt of registered or certified letter. Certificates of Insurance shall contain transcripts from the proper office of the insurer, evidencing in particular those insured, the extent of the insurance, the loca- tion and the operations to which the insurance applies, the expiration date, and the above mentioned notice of cancellation clause. 3.19 Final Clean - up Upon the completion of the work and before acceptance and final payment will be made, the Contractor shall clean and remove from the site of the work, surplus and discarded materials, temporary structures and debris of every kind. He shall leave the site of the work in a neat and orderly condition at least equal to that which originally existed. Surplus and waste materials removed from the site of the work shall be disposed of at locations satisfactory to the Engineer. In the event Contractor fails or refuses to clean and remove surplus materials and debris as above provided, the Owner or Engineer may do so, or cause same to be done, at the Contractor's expense and the reasonable cost thereof shall be deducted from the final payment. 3.20 Guarantee Against Defective Work The contractor warrants the materials and workmanship and that the work is in conformance with the plans and specifications included in this contract for a period of one year from the date of acceptance of the project. Said warranty binds the contractor to correct any work that does not conform with such plans and specifications or any defects in workmanship or materials furnished under this contract which may be dis- covered within the said one year period. The Contractor shall at his own expense correct such defect within thirty days after receiving written notice of such defect from the Owner or Engineer by repairing same to the condition called for in the contract documents and plans and specifications. Should the Contractor fail or iefuse to repair such defect within the said thirty day period or to provide acceptable assurances that such repair work will be completed within a reasonable time thereafter, the Owner may repair or cause to be repaired any such defect at the Contractor's expense. 3.21 Testing of Materials Unless otherwise specified, testing of all materials to be incorporated into the project will be as directed by the Engineer at the expense of the Owner. All retesting for work rejected on the basis of test results will be at the expense of the Contractor and the extent of the retesting shall be determined by the Engineer. The Engineer may require additional testing for failing tests and may require two passing retests before ac- ceptance will be made by the Owner. The testing laboratory will be designated by the Owner. All materials to be incorporated into the project must meet the requirements of these specifications. For manufactured materials such as reinforcing steel, expansion joint materials, concrete pipe, cement, mis- cellaneous steel, cast iron materials, etc., the Contractor will be required to furnish a manufacturer's cer- tificate stating that the material meets the requirements specified for this project.

Prosecution and Progress 4.01 Time and Order of Completion It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Con- tractor shall be allowed to prosecute.his work at such times and seasons, in such order of precedence, and in such manner as shall be most conducive to economy of construction; provided, however, that the order and the time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications, and within the time of com- pletion designated in the Proposal; provided, also, that when the Owner is having other work done, either by contract or by his own force, the Engineer may direct the time and manner of constructing the work done under this contract, so that conflict will be avoided and the construction of the various works being done for the Owner shall be harmonized. The Contractor shall submit, at such times as may reasonably be requested by the Engineer, schedules which shall show the order in which the Contractor proposes to carry on the work, with dates at which the Contractor will start the several parts of the work, and estimated dates of completion of the several parts. 4.02 Extension of Time Should the Contractor be delayed in the completion of the work by any act or neglect of the Owner or Engineer, or of any employee of either, or by other contractors employed by the Owner, or by changes ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoid- able cause or causes beyond the Contractor's control, or by any cause which the Engineer shall decide justifies the delay, then an extension of time shall be allowed for completing the work, sufficient to com- pensate for the delay, the amount of the extension to be determined by the Engineer, provided, however, that the Contractor shall give the Engineer prompt notice in writing of the cause of such delay. 4.03 Hindrances and Delays No claims shall be made by the Contractor for damages resulting from hindrances or delays from any cause (except where the work is stopped by order of and for the convenience of the Owner) during the progress of any portion of the work embraced in this contract. In case said work shall be stopped by the act of the Owner, then such expense as in the judgment of the Engineer is caused by such stoppage of said work shall be paid by the Owner to the Contractor. 5. Measurement and Payment 5.01 Quantities and Measurements No extra or customary measurements of any kind will be allowed, but the actual measured and /or com- puted length, area, solid contents, number and weight only shall be considered, unless otherwise spe- cifically provided. 5.02 Estimated Quantities This agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approxi- mate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and the material furnished. GC -13 • Where payment is based on the unit price method, the Contractor agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contemplated and contained in the proposal; provided, however, that in case the actual quan- tity of any major item should become as much as 20% more than, or 20% less than the estimated or con- templated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a revised consideration upon the portion of the work above or below 20% of the estimated quantity. A "Major Item" shall be construed to be any individual bid item incurred in the proposal that has a total cost equal to or greater than five (5) per cent of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices. Any revised consideration is to be determined by agreement between the parties, otherwise by the terms of this Agreement, as provided under "Extra Work." 5.03 Price of Work In consideration of the furnishing of all the necessary labor, equipment and material, and the completion of all work by the Contractor, and on the completion of all work and on the delivery of all material em- braced in this Contract in full conformity with the specifications and stipulations herein contained, the Owner agrees to pay the Contractor the prices set forth in the Proposal hereto attached, which has been made a part of this contract. The Contractor hereby agrees to receive such prices in full for furnishing all material and all labor required for the aforesaid work, also for all expense incurred by him, and for well and truly performing the same and the whole thereof in the manner and according to this Agreement. 5.04 Partial Payments On or before the 1st day of each month, the Contractor shall submit to the Engineer a statement showing the total value of the work performed up to and including the 25th day of the preceding month. The state- ment shall also include the value of all sound materials delivered on the job site and to be included in the work all partially completed work whether bid as a lump sum or a unit item which in the opinion of the Engineer is acceptable. The Engineer shall examine and approve or modify and, approve such statement. The Owner shall then pay the Contractor on or before the 10th day of the current month the total amount of the approved statement, Less 10 per cent of the amount thereof, which 10 per cent shall be retained until final payment, and further less all previous payments and all further sums that may be retained by the Owner under the terms of this Agreement. It is understood, however, that in case the whole work• be near to completion and some unexpected and unusual delay occurs due to no fault or neglect on the part of the Contractor, the Owner may —upon written recommendation of the Engineer pay a reasonable and equitable portion of the retained percentage to the Contractor: or the Contractor at the Owner's option, may be relieved of the obligation to fully complete the work and, thereupon, the Contractor shall receive payment of the balance due him under the contract subject only to the condi- tions stated under "Final Payment." 5.05 Use of Completed Portions The Owner shall have the right to take possession of and use any completed or partially completed por- tions of the work, notwithstanding the time for completing the entire work or such portions may not have expired but such taking possession and use shall not be deemed an acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost of or delays the work, the Contractor shall be entitled to such extra compensation, or extension of time, or both, as the Engineer may determine. The Contractor shall notify the Engineer when, in the Contractor's opinion, the contract is "substan- tially completed" and when so notifying the Engineer, the Contractor shall furnish to the Engineer in writing a detailed list of unfinished work. The Engineer will review the Contractor's list of unfinished work and will add thereto such items as the Contractor has failed to include. The "substantial comple- tion" of the structure or facility shall not excuse the Contractor from performing all of the work under- taken, whether of a minor or major nature, and thereby completing the structure or facility in accor- dance with the Contract Documents. GC -14 Rev. 7.1.75 1 1 1 1 1 1 1 1 ') 1 1 1 1) 1 1 1 1 1 1 1 1 1 1 5.06 Final Completion and Acceptance Within ten (10) days after the Contractor has given the Engineer written notice that the work has been completed, or substantially completed, the Engineer and the Owner shall inspect the work and within said time, if the work be found to be completed in accordance with the Contract Documents, the Engi- neer 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 Con- tractor or to advise the Contractor in writing of the reason for non - acceptance. 5.07 Final Payment Upon the issuance of the Certificate of Completion, the Engineer shall proceed to make final measure- ments arid prepare final statement for 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 before the 30th day, and before the 35th day, after the date of the Certificate of Completion, the balance due the Contractor under the terms of this 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 fulfill- ment of any warranty which may be required. 5.08 Payments Withheld The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of: (a) Defective work not remedied or other obligations hereunder not done. (b) Claims filed or reasonable evidence indicating probable filing of claims. (c) Failure of the Contractor to make payments properly to subcontractors or for material or labor. (d) Damage to another contractor. (e) Reasonable doubt that the work can be completed for the unpaid balance of the contract amount. (f) Reasonable indication that the work will not be completed within the contract time. When the above grounds are removed or the Contractor provides a Surety Bond satisfactory to the Owner, which will protect the Owner in the amount withheld, payment shall be made for amounts withheld because of them. 5.09 Delayed Payments Should the Owner fail to make payment to the Contractor of the sum named in any partial or final state- ment, when payment is due, then the Owner shall pay to the Contractor, in addition to the sum shown as due by such statement, interest thereon at the rate of 6% per annum, unless otherwise specified, from date due as provided under 'partial payments' and 'final payments,' until fully paid, which shall fully liquidate any injury to the contractor growing out of such delay in payment. It is expressly agreed that delay by the Owner in making payment to the Contractor of the sum named in any partial or final statement shall not constitute a breach of this contract on the part of the Owner nor an abandonment thereof nor shall it to any extent or for any time relieve the Contractor of his obligations to fully and completely perform here- under. 6. Extra Work and Claims 6.01 Change Orders Without invalidating this Agreement, the Owner may, at any time or from time to time, order additions, deletions or revisions to the work; such changes will be authorized by Change Order to be prepared by the Engineer for execution by the Owner and the Contractor. The Change Order shall set forth the basis for any change in contract price, as hereinafter set forth for Extra Work, and any change in contract time which may result from the change. Rev. 7.1.75 GC -15 In the event the Contractor shall refuse to execute a Change Order which has been prepared by the Engineer and executed by the Owner, the Engineer may in writing instruct the Contractor to proceed with the work as set forth in the Change Order and the Contractor may make claim against' the Owner for Extra Work involved therein, as hereinafter provided. 6.02 Minor Changes The Engineer may authorize minor changes in the work not inconsistent with the overall intent of the Contract Documents and not involving an increase in Contract Price. If the Contractor believes that any minor change or alteration authorized by the Engineer involves Extra Work and entitles him to an in- crease in the Contract Price, the Contractor shall make written request to the Engineer for a written Field Order. In such case, the Contractor by copy of his communication to the Engineer or otherwise in writing shall advise the Owner of his request to the Engineer for a written Field Order and that work involved may result in an increase in the Contract Price. Any request by the Contractor for a change in Contract Price shall be made prior to beginning the work covered by the proposed change. 6.03 Extra Work It is agreed that the basis of compensation to the Contractor for work either added or deleted by a Change Order or for which a claim for Extra Work is made shall be determined by the unit prices upon which this contract was bid to the extent such work can be fairly classified within the various work item descriptions and for work items that cannot be so classified by one or more of the following methuds: Method (A) By agreed unit prices; or Method (B) By agreed lump sum; or Method (C) If neither Method (A) nor Method (B) be agreed upon before the Extra Work is commenced, then the Contractor shall be paid the "actual field cost" of the work, plus fifteen (15) percent. In the event said Extra Work be performed and paid for under Method (C), then the provisions of this paragraph shall apply and the "actual field cost" is hereby defined to include the cost to the Contractor of all workmen, such as foreman, timekeepers, mechanics and laborers, and materials, supplies, trucks, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual equipment, for the time actually employed or used on such Extra Work, plus actual transporta- tion charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, including Social Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of premiums on Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property Damage and Workmen's Compensation, and all other insurance as may be required by any law or ordinance, or directed by the Owner, or by them agreed to. The Engineer may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made avail- able to the Engineer. The Engineer or Owner may also specify in writing, before the work commences, the method of doing the work and the type and kind of machinery and equipment to be used; otherwise these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be determined by using 100 per cent, unless otherwise specified, of the latest schedule of Equipment Ownership Expense adopted by the Associated General Contractors of America. Where practicable the terms and prices for the use of machinery and equipment shall be incor- porated in the Written Extra Work Order. The fifteen (15 %) per cent of the "actual field cost" to be paid the Contractor shall cover and compensate him for his profit, overhead, general superintendence and field office expense, and all other elements of cost and expense not embraced within the "actual field cost" as herein defined, save that where the Contractor's Camp or Field Office must be maintained pri- GC -16 1 1 1 1 1 1 1 warily on account of such Extra Work; then the cost to maintain and operate the same shall be included in the "actual field cost." • No claim for Extra Work of any kind will be allowed unless ordered in writing by the Engineer. In case any orders or instructions, either oral or written, appear to the Contractor to involve Extra Work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the Engineer for written order authorizing such Extra Work. Should a difference of opinion arise as to what does or does not constitute Extra Work, or as to the payment therefor, and the Engineer insists upon its performance, the Contractor shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as pro- vided under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to arbitration. as hereinbelow provided. 6.04 Time of Filing Claims It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Engineer within thirty (30) days after the Engineer has given any directions, order or instruction to which the Contractor desires to take exception. The Engineer shall reply within thirty (30) days to such written exceptions by the Contractor and render his final decision in writing. In case the Contractor should appeal from the Engineer's decision, any demand for arbitration shall be filed with the Engineer and the Owner in writing within ten (10) days after the date of delivery to Contractor of the Engineer's final decision. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to any claims by either party, except claims by Owner for defective work or enforcement of warranties and except as noted otherwise in the contract documents. 6.05 Arbitration All questions of dispute under this Agreement shall be submitted to arbitration at the request of either party to the dispute. The parties may agree upon one arbiter, otherwise, there shall be three, one named in writing by each party, and the third chosen by the two arbiters so selected; or if the arbiters fail to select a third within ten (10) days, he shall be chosen by a District Judge serving the County in which the major portion of the project is located, unless otherwise specified. Should the party demanding arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse, and the decision of the Engineer shall be final and binding on him. Should the other party fail to choose an arbiter within ten (10) days, the Engineer shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take ex parte proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any questions submitted to arbitration under this contract shall be a condition precedent to any right of legal action. The decision of the arbiter or arbiters may be filed in court to carry it into effect. The arbiters, if they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and if the appeal was taken without reasonable caus "e, they may award damages for any delay occasioned thereby. The arbiters shall fix their own compensation unless otherwise provided by agreement, and shall assess the cost and charges of the arbitration upon either or both parties. The award of the arbiters must be made in writing. 7. Abandonment of Contract 7.01 Abandonment by Contractor In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after writ- ten notification from the Owner, or the Engineer, or if the Contractor fails to comply with the orders of GC -17 the Engineer, when such orders are consistent with the Contract Documents, then, and in that case, where performance and payment bonds exist, the Sureties on these bonds shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. After receiving said notice of abandonment the Contractor shall not remove from the work any machin- ery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under contract for the work, may be held for use on the work by the Owner or the Surety on the performance bond, or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefor (except when used in connection with Extra Work, where credit shall be allowed as provided for under Section 6, Extra Work and Claims), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. Where there is no performance bond provided or in case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for, within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (1) The Owner may thereupon employ such force of men and use such machinery, equipment, tools, materials and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said Con- tractor, and expense so charged shall be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said Contractor, then the Contractor and /or his Surety shall pay the amount of such excess to the Owner, or (2) The Owner under competitive bids, taken after notice published as required by law, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case there is any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract, such increase shall be charged to the Contractor and the Surety shall be and remain bound there- for. However, should the cost to complete any such contract prove to be less than would have been the cost to complete under this contract, the Contractor and /or his Surety shall be credited therewith. When the work shall have been substantially completed the Contractor and his Surety shall be so noti- fied and Certificates of Completion and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be issued. A complete itemized statement of the contract accounts, certified to by the Engineer as being correct, shall then be prepared and delivered to the Contractor and his Surety, whereupon the Con- tractor and /or his Surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement, within fifteen (15) days after the date of such Certificate of Completion. In the event the statement of accounts shows that the cost to complete the work is less than that which would'have been the cost to the Owner had the work been completed by the Contractor under the terms of this contract; or when the Contractor and /or his Surety shall pay the balance shown to be due by them to the owner, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be turned over to the Contractor and /or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor and /or his Surety fail to pay the amount due the Owner within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract, provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either public or private sale, with or without notice, as the GC -18 1 1 1 1 1 r - 1 1 1 1 - 1 1 1 1 1 1 1 1 1 1 Owner may elect. The Owner shall release any machinery, equipment, tools, materials, or supplies, which remain on the work, and belong to persons other than the Contractor or his Surety, to their proper owners. The books on all operations provided herein shall be opened to the Contractor and his Surety. 7.02 Abandonment by Owner In case the Owner shall fail to comply with the terms of this contract, and should fail to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools and equipment, and all materials on the site of work that have not been included in payments to the Contractor and have not been wrought into the work. And thereupon the Engineer shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Contractor (at the prices stated in the attached proposal where unit prices are used), the value of all partially completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor to carry the whole work to completion and which cannot be utilized. The Engineer shall then make a final statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this Agreement and shall certify same to the Owner who shall pay to the Contractor on or before thirty (30) days after the date of the notification by the Contractor the balance shown by said final statement as due the Contractor, under the terms of this Agreement. 8. Subcontractors 8.01 Award of Subcontracts for Portions of the Work Unless otherwise specified in the Contract Documents or in the Instructions to Bidders, the Contractor, as soon as practicable after the award of the Contract, shall furnish to the Engineer in writing for accep- tance by the Owner and the Engineer a list of the names of the Subcontractors proposed for the principal portions of the work. The Engineer shall promptly notify the Contractor in writing if either the Owner or the Engineer, after due investigation, has reasonable objection to any Subcontractor on such list and does not accept him. Failure of the Owner or Engineer to make objection promptly to any Sub- contractor on the list shall constitute acceptance of such Subcontractor. The Contractor shall not contract with any Subcontractor or any person or organization (including those who are to furnish materials or equipment fabricated to a special design) proposed for portions of the work designated in the Contract Documents or in the Instructions to Bidders or, if none is so desig- nated, with any Subcontractor proposed for the principal portions of the work who has been rejected by the Owner and the Engineer. The Contractor will not be required to contract with any Subcontractor or person or organization against whom he has a reasonable objection. If the Owner or Engineer refuses to accept any Subcontractor or person or organization on a list sub- mitted by the Contractor in response to the requirements of the Contract Documents or the Instructions to Bidders, the Contractor shall submit an acceptable substitute and the Contract amount shall be increased or decreased by the difference in cost occasioned by such substitution and an appropriate change order shall be issued; however, no increase in the Contract amount shall be allowed for any such substitution unless the Contractor has acted promptly and responsively in submitting for acceptance any list or lists of names as required by the Contract Documents or the Instructions to Bidders. If the Owner or the Engineer requires a change of any proposed Subcontractor or person or organization previously accepted by them, the Contract amount shall be increased or decreased by the difference in cost occasioned by such change and an appropriate Change Order shall be issued. The Contractor shall not make any substitution for any Subcontractor or person or organization who has been accepted by the Owner and the Engineer, unless the substitution is acceptable to the Owner and the Engineer. "GC-I9 8.02 Subcontractual Relations All work performed for the Contractor by a Subcontractor shall be pursuant to an appropriate' written agreement between the Contractor and the Subcontractor (and where appropriate between Subcontrac- tors and Sub - subcontractors) which shall contain provisions that: (1) preserve and protect the rights of the Owner and Engineer under the Contract with respect to the work to be performed under the subcontract so that the subcontracting thereof will not prejudice such rights; (2) require that such work be performed in accordance with the requirements of the Contract Docu- ments; (3) require submission to the Contractor of the applications for payment under each subcontract to which the Contractor is a party, in reasonable time to enable the Contractor to apply for payment in accordance with this contract; (4) require that all claims for additional costs, extensions of time, damages for delays or otherwise with respect to subcontracted portions of the work shall be submitted to the Contractor (via any Subcontractor or Sub- subcontractor where appropriate) in sufficient time so that the Contractor may comply in the manner provided in the Contract Documents for like claims by the Contractor upon the Owner; (5) obligate each subcontractor specifically to consent to the provisions of this section. A copy of all such Subcontract Agreements shall be filed by the Contractor with the Engineer before the Subcontractor shall be allowed to commence work. 8.03 Payments to Subcontractors The Contractor shall pay each Subcontractor, upon receipt of payment from the Owner, an amount directly based upon the value of the work performed and allowed to the Contractor on account of such Subcontractor's work, less the percentage retained from payments to the Contractor. The Contractor shall also require each Subcontractor to make similar payments to his subcontractors. If the Engineer fails to approve a payment for any cause which is the fault of the Contractor and not the fault of a particular Subcontractor, the Contractor shall pay the Subcontractor on demand, made at any time after the Certificate for Payment should otherwise have been issued, for his work to the extent com- pleted, less the retained percentage. The Engineer may, on request and at his discretion, furnish to any Subcontractor, if practicable, information regarding percentages of completion certified to the Contractor on account of work done by such Subcontractors. Neither the Owner nor the Engineer shall have any obligation to pay or to see to the payment of any moneys to such Subcontractor except as may otherwise be required. 9. Separate Contracts 9.01 Owner's Right to Award Separate Contracts The Owner reserves the right to award other contracts in connection with other portions of the project under these or similar conditions of the Contract. When separate contracts are awarded for different portions of the Project, "The Contractor" in the contract documents in each case shall be the contractor who signs each separate contract. 9.02 Mutual Responsibility of Contractors The Contractor shall afford other contractors reasonable opportunity 'for the introduction and storage of their materials and equipment and the execution of their work, and shall properly connect and coor- dinate his work with theirs. GC -20 1 1 1 1 1 If any part of the Contractor's work depends for proper execution or results upon the work of any other separate contractor, the Contractor shall inspect and promptly report to the Engineer any apparent discrepancies or defects in such work that render it unsuitable for such proper execution and results. Failure of the Contractor so to inspect and report shall constitute an acceptance of the other contractor's work as fit and proper to receive his Work, except as to defects which may develop in the other separate contractor's work after the execution of the Contractor's Work. Should the Contractor cause damage to the work or property of any separate contractor on the project, the Contractor shall, upon due notice, settle with such other contractor by agreement or arbitration, if he will so settle. If such separate contractor sues the Owner or initiates an arbitration proceeding on account of any damage alleged to have been so sustained, the Owner shall notify the Contractor who shall defend such proceedings at the Contractor's expense, and if any judgment or award against the Owner arises therefrom the Contractor shall pay or satisfy it and shall reimburse the Owner for all attorney's fees and court or arbitration costs which the Owner has incurred. 9.03 Cutting and Patching under Separate Contracts The Contractor shall be responsible for any cutting, fitting and patching that may be required to com- plete his work except as otherwise specifically provided in the Contract Documents. The Contractor shall not endanger any work of any other contractors by cutting, excavating or otherwise altering any work and shall not cut or alter the work of any other contractor except with the written consent of the Engineer. Any costs caused by defective or ill-timed work shall be borne by the party responsible therefor. 10. Protection of Persons and Property 10.01 Safety Precautions and Programs The Contractor shall be responsible for initiating, maintaining and supervising all safety precautions and programs in connection with the work. 10.02 Safety of Persons and Property The Contractor shall take all reasonable precautions for the safety of, and shall provide all reasonable protection to prevent damage, injury, or loss to: (1) all employees on the work and all other persons who may be affected thereby; (2) all the work and all materials and equipment to be incorporated therein, whether in storage or or off the site, under the care, custody or control of the Contractor or any of his Subcontractors or Sub - Subcontractors; and (3) other property at the site or adjacent thereto, including trees, shrubs, lawns, walks, pave- ments, fences, roadways, structures and utilities not designated for removal, relocation or replacement in the course of construction. The Contractor shall comply with all applicable laws, ordinances, rules, regulations and lawful orders of any public authority having jurisdiction for the safety of persons or property or to protect them from damage, injury or loss. He shall erect and maintain, as required by existing conditions and progress of the work, all reasonable safeguards for safety and protection, including posting danger signs and other warnings against hazards, promulgating safety regulations and notifying owners and users of adjacent utilities. When the use or storage of explosives or other hazardous materials or equipment is necessary for the execution of the work, the Contractor shall exercise the utmost care and shall carry on such activities under the supervision of properly qualified personnel. Rev. 7.1.75 GC -21 All Blasting, including methods of storing and handling explosives and highly inflammable materials, shall conform to Federal, State, Local Laws and Ordinances.

Satisfactory templates shall be provided as required by the Engineer. 340.5 Stockpiling Aggregates Prior to stockpiling of aggregates, the area shall be cleaned of trash, weeds and grass and be relatively smooth. Aggregates shall be stockpiled in such a manner as to prevent mixing of one aggregate with another. Coarse aggregates for Type B and Type C shall be separated into at least two stockpiles of different gradation, such as a large coarse aggregate and a small coarse aggre- gate stockpile and such that the grading requirements of the specified type will be met when the piles are combined in the asphaltic mixture. Suitable equipment of acceptable size shall be furnished by the Contractor to load out the stockpiles such that segregation of the aggregates does not occur. 340.6 Mixing (1) General (a) Asphaltic Mixture The asphaltic mixture from each type of mixer shall be a temperature between 240 F and 350 F when dis- charged from the mixer and shall be adjusted to provide the best compaction temperature for the weather conditions. The Contractor will determine the temperature, within the above limitations and the mixture when discharged from the mixer shall not vary from this selected temperature more than 25 F. (2) Batch Type Mixer In the charging of the weigh box and in the charging of the mixer from the weigh box, such methods or devices shall be used as are necessary to discharge the mixer in a manner which will prevent segregation. (3) Dryer -Drum Mixer The amount of aggregate and asphaltic materials entering the dryer -drum mixer and the rate of travel through the mixing unit shall be so coordinated that a uniform mixture of the specified grading and asphalt content will be produced without segregation. 340.7 Storing Mixture Temporary storing or holding of the asphaltic mixture in insulated surge or storage systems may be used, provided the mixture is not stored overnight or for more than 15 hours and the mixture does not segregate in or upon discharge from the system. The mixture when discharged from the plant surge storage bin shall have a moisture content not greater than 1 percent by weight and must be of equal quality to that coming out of the mixer. The moisture content shall be determined in accordance with SDHPT Test Method Tex - 212 -F, Part II. 340.8Construction Methods It shall be the responsibility of the Contractor to produce, transport, place and compact the specified paving mixture in accor- dance with these specifications and provide a safe environment to enable inspection forces to take samples and check the plant. Prior to placing HMAC, the base shall be proof rolled and any soft spots repaired and the area proof rolled again. The asphaltic mixture, when placed with a motor grader for leveling, shall not be placed when air temperature is below 50 F and fdlling. The air temperature shall be taken in the shade away from artificial heat. Mat thickness of 1' inches and less shall not be placed when the temperature of the surface on which the mat is to be placed is below 50 F. All asphaltic mixture, except that described above for leveling, shall be placed with a spreading and finishing machine. If, after being discharged from the mixer and prior to placing, the temperature of the asphaltic mixture is 50 F or more below the tempera- ture established, all or any part of the load may be rejected and payment will not be made for the rejected material. Any material placed which is too cool to compact properly shall be removed and replaced with material which meets the specifications. Adjacent to flush curbs, gutters, liners and structures, the surface shall be finished uniformly high so that when compacted It will be slightly above the edge of the curb and flush structure. The compacted thickness of the asphaltic concrete courses shall be as indicated. Where the thickness of the surface course is specified to be more than 2 inches, the work shall be accomplished in equal lifts, unless otherwise indicated. When the surface is to be constructed in stages and traffic is permitted on the initial layer, each layer shall be not less than 1 inch. The final lift of HMAC shall not be placed adjacent to an existing cured rounded edge asphalt surface until the existing surface has been prepared. Page5 04/17/86 340 (1) Prime Coat If a prime coat is indicated, it shall be applied conforming to Item No. 306, "Prime Coat ", except the application temperature shall be as provided above. The asphaltic concrete shall not be applied on a previously primed flexible base until the primed base has cured to the satisfaction of the Engineer. (2) Tack Coat If a tack coat is indicated, it shall be applied conforming to Item No. 307, "Tack Coat ". Before the asphaltic mixture is placed, the surface upon which the tack coat is to be placed shall be cleaned thoroughly to the satisfaction of the Engineer. The surface shall be given a uniform application of tack coat using asphaltic materials of this specification. This tack coat shall be applied, as directed by the Engineer. Where the mixture will adhere to the surface of which it is to be placed without the use of a tack coat, the tack coat may be eliminated by the Engineer. All contact surfaces of curbs and structures and all Joints shall be painted with a thin uniform coat of the asphaltic material meeting the requirements for tack coat. The tack coat shall be rolled with a light pneumatic tire roller when directed by the Engineer. (3) Compacting The mix shall be compressed thoroughly and uniformly compacted immediately after placing to the required density. All compaction rolling shall be complete before the mat cools below 175 F. Minor polishing rolling may be undertaken on the mat below the above temperature. All rollers must be in good mechanical condition. Necessary precautions shall be taken to prevent the dropping of gasoline, oil, grease or other foreign matter on the pavement, either when the rollers are in operation or when standing. It is the intent of this specification that the material be placed and compacted to a minimum of 92.5 percent of the maximum theoretical density as determined by SDHPT Tex - 227 -F. The Engineer will secure 6 inch core samples or sections of completed asphaltic pavement lifts for approximately every 2,000 square yards or part thereof, of asphaltic concrete pavement placed. The in place density at the sampled locations shall be determined by the fol- lowing equation: 340 04/17/86 Page 6 Percent in place Density = GT x 100 Where GA = Bulk specific gravity of core when tested in accordance with Tex -207 -F GT = Maximum theoretical specific gravity of combined cores when tested in accordance with Tex -227 -F The Contractor shall patch the surface where specimens are taken with no extra payment being made for this work. The Engineer will remove the asphaltic concrete pavement specimen on the day following placement or as soon as practicable thereafter. Other methods of determining in place density which correlate satisfactorily with those results obtained by cores or sections may be used. The initial sampling and testing of in place asphalt concrete will be at no cost to the Contractor, except for the cost of material and restoration of damage by testing. Retesting expense will conform to Section 00344, "Testing Labora- tory Services ". (4) Surface Tests The surface of the pavement, after compaction, shall be smooth and true to the established line, grade and cross section, and when tested with a 10 foot straightedge placed parallel to the centerline of the roadway or tested by other equivalent and acceptable means, except as provided herein, the maximum deviation shall not exceed /e inch in 10 feet and any point in the surface not meeting this requirement shall be corrected. The completed surface shall meet the approval of the Engineer for riding surface, finish and appearance. (5) Opening to Traffic The pavement shall be opened to traffic as soon as possible after temporary pavement markings or permanent pavement markings are in place as indicated and the Engineer concurs to the opening. The Contractor's attention is directed to the fact that all construction traffic allowed on pavement open to the public will be subject to the City Ordinances and State Laws governing traffic on streets and highways. Surface raveling, cracking, segregation and other defects shall be corrected at the Contractor's expense as directed by the Engineer. Traffic control expense for undertaking the repairs will be at the Contractor's expense. 1 -1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 340.9 Acceptance Plan (1) General The surface testing shall be completed prior to the use of pay adjustment factors for acceptance of gradation, as- phalt content, stability, in place density and pavement thickness. The pay adjustments will be based upon the results of tests performed on samples taken in a random manner. Pay adjustment for private development work shall con- form to Item No. 1804, "General Obligations and Responsibility of the Owner ". (a) Sampling The Engineer will determine the sampling schedules for random testing in accordance with SDHPT Test Method Tex - 225 -F. Samples will be taken at the plant or on the project site, as determined by the Engineer. The Engineer may require that either cores or sections of asphaltic pavement be taken al locations selected by the Engineer. (b) Testing Determination of acceptability will be based on tests performed by the City or its laboratory. However, truck loads of the asphaltic mixture that are visually inspected by the Engineer and can reasonably be expected not to meet specification requirements, such as a mixture containing segregated material, low mixture tempera- ture, a deficiency or excess of asphalt, or otherwise unsuitable for placing on the roadway shall not be used. Any mixtures containing segregated areas, deficiency or excess of asphalt or otherwise unsuitable that is placed on the roadway shall be removed and replaced with satisfactory material at the Contractor's expense. Acceptability will be based on the mean of the job values from the City tests of the project materials. (2) Gradation and Asphalt Content The acceptability of mixture gradation and asphalt content will be based on the mean of a minimum of 3 tests taken by the City's laboratory. If the mean value of acceptance tests of the project, for a particular sieve or sieves or for asphalt content deviates from the project design by more than the tolerances shown and the Engineer determines that the material need not be removed and replaced, the project may be accepted at a reduced Contract Unit Price as follows: SPECIFIED SEIVE SIZE Passing inch GRADATION ACCEPTANCE SCHEDULE DEVIATION OF THE PERCENT CONTRACT UNIT MEAN FROM THE DESIGN PRICE REDUCTION 0 -5.0 0 5.1 + 5 Passing 143 inch, 3 /e inch 0 — 5.0 ' 0 to #4, 5.1 —7.0 2 #4 to #10, Total retained on #10 7.1 + 4 #10 to #40, #40 to #80, 0 — 5.0 0 5.1 + • , .. .. 5 Passing #200 - 0 — 5.1 0 3.1 + 5 ASPHALT CONTENT ACCEPTANCE SCHEDULE PERCENT DEVIATION PERCENT CONTRACT UNIT FROM INTENDED PRICE REDUCTION ASPHALT CONTENT • 0 -0.3 0 . 0.31 -0.4 10 0.41 -0.5 20 over 0.5 100 and the Engineer may require a seal coat or removal and replacement at Contractor's expense. Page 7 04/17/86 340 (3) Stability A minimum of 3 tests will be taken for stability and acceptance determinations. The Contractor shall produce a consistent mixture. If the project is to receive a pay factor of 1.00 the mean value of the considered stabilities shall not be less than 40 nor greater than 55, when tested in accordance with Test Method Tex - 208 -F. If the mean value falls outside this range a reduction will be made in accordance with the following table: HVEEM STABILITY ACCEPTANCE SCHEDULE PERCENT CONTRACT UNIT STABILITY VALUE PRICE REDUCTION 37 -40 10 40 -55 0 55 -60 10 60 and above 60 An asphalt mixture in place that has a stability below 37 will not be paid for by the City and will be removed and replaced at the Contractor's expense. The project may be accepted at no cost to the City if such request is made by the Contractor and approved by the Engineer. The replacement of the project will be subject to the same acceptance plan as original material. (4) In Place Density A minimum of 3 tests will be taken for in place density. The density of the mixture as determined in accordance with SDHPT Test Method Tex - 207 - F and SDHPT Test Method Tex - 227 - F will be used to determine compliance and will be measured and averaged. If the mean value of the considered densities is greater or less than 95 and the Engi- neer determines that the material need not be removed and replaced, the project may be accepted at a reduced unit price as follows: 340 04/17/86 Page 8 IN PLACE DENSITY ACCEPTANCE SCHEDULE PERCENT OF DEVIATION PERCENT CONTRACT UNIT FROM 95 PRICE REDUCTION 0 -2.5 0 2.5-3.0 5 More than 3.1 100 and the Engineer may require re- moval and replacement at Contrac- tor's expense. (5) Segregation Materials placed in which segregation is present shall be removed and replaced. (6) Straightedge and Template The Contractor shall produce a final pavement surface which meets the straightedge and template requirements. If techniques produce a pavement which doesn't meet the straightedge and template requirements, the surface will be overlaid with a 1Y2 inch layer of HMAC unless the surface can be corrected by milling which will not reduce the thickness of the HMAC below the minimums indicated. No additional compensation will be made for any corrective work required of the Contractor. (7) Thickness The Contractor shall produce a pavement with the minimum thickness indicated. Should the mean of the core tests indicate a variance in thickness under the plan requirements, the Project shall be accepted at a reduced contract unit price as follows: VARIANCE INCHES 0 —pia 9/ 17 /64 - over 3 /a PERCENT CONTRACT UNIT PRICE TO BE PAID 100 95 75 overlay 1 inch 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 340.10 Measurement Method A Method B End If the thickness of the asphaltic concrete proves to be less than required, the Contractor may replace or overlay the deficient areas as agreed by the Engineer. Overlays will be a thickness not less than 11/2 inches. Overlays will require the milling of asphalt adjacent to concrete curb and gutters to maintain the transverse profile. Asphaltic concrete pavement will be measured by the ton (2,000 pounds) of asphaltic concrete pavement of the type actu- ally used in the completed and accepted work in accordance with the plans and specifications for the project. When the dryer -drum process is used, measurement of the tonnage used shall be made on truck scales. Asphaltic concrete pavement will be measured by the square yard of the specified total thickness of the type actually used in the completed and accepted work in accordance with the plans and specifications. Multiple lifts will be considered as one for square yard measurement purposes. 340.10 Payment The work performed and materials furnished as prescribed by this item and measured as provided under "Measurement" will be paid for at the unit prices bid or the pay adjusted unit price for "Asphaltic Concrete Pavement ", of the types and lifts specified, which prices shall be full compensation for furnishing all materials, freight involved; for all heating, mixing, hauling, cleaning the existing base course or pavement, saw cutting placing asphaltic concrete mixture, rolling and finishing, for all manipulations, labor, tools, equipment, temporary pavement markings and incidentals necessary to complete the work.
