Prior to submitting any proposal, bidders are required to read the plans, specifications, proposal, contract and bond forms carefully; to inform themselves by their independent research, test and investigation of the difficulties to be encountered and judge for themselves of the accessibility of the work and all attending circumstances affecting the cost of doing the work and the time required for its completion and obtain all information required to make an intelligent proposal. 2. Should the bidder find discrepancies in, or omissions from the plans, specifications, or other documents, or should he be in doubt as to their meaning, he should notify at once the Engineer and obtain clarification or addendum prior to submitting any bid. 3. It shall be the responsibility of the bidder to see that his bid is received at the place and time named in the Notice to Bidders. Bids received after closing time will be returned unopened. 4.

Failure to execute the construction contract within ten (10) days of written notification of award or failure to furnish the performance bond, or letter of credit if applicable, and payment bond as required by item 11 above, shall be just cause for the annulment of the award. In case of the annulment of the award, the proposal guarantee shall become the property of the City of Round Rock, not as a penalty, but biddoc.mst/spec BD - as a liquidated damage. 14. No contract shall be binding upon the City of Round Rock until it has been signed by its Mayor after having been duly authorized to do so by the City Council. 15.

Definition of Terms General Conditions of Agreement 1.01 Owner, Contractor and Engineer The Owner, the Contractor and the Engineer and those persons or organizations identified as such in the Agreement are referred to throughout the Contract Documents as if singular in number and masculine in gender. The term "Engineer" means the Engineer or his duly authorized representative. The Engineer 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, Instructions to Bidders, Proposal, Signed Agreement, Performance and Payment Bonds (when required), Special Bonds (when required), General Conditions of the Agreement, Construction Specifications, Plans and all modifications thereof incorporated in any such 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 the 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 Subcontractor The term "Subcontractor," as employed herein, includes only those having a direct contract with the Contractor. It includes one who furnishes material worked to 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 Sub - Subcontractor The term "Sub- Subcontractor" means one who has a direct or indirect contract with a Subcontractor to perform any of the work at the site. 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. GC -5 1.05 Written Notice 1.06 Work Written notice shall be deemed to have been duly served if delivered in person to the individual or to an officer of the corporation for whom it is intended, or if delivered to or sent by registered mail to the last business address known to him who gives the notice. The Contractor shall provide and pay for all materials, machinery, 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 the kind and quality of materials. Materials or work described in words which, when so applied, have a well -known technical or trade meaning shall be held to refer to such recognized standards. 1.07 Extra Work The term "Extra Work" shall be understood to mean and include all work that may be required by the Engineer or the 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. 1.08 Working Day The term "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. 1.09 Calendar Day The term "Calendar Day" is defined as any day of the week or month, no days being excepted. 1.10 Substantially Completed The term "Substantially Completed" shall be understood to mean that the structure has been made suitable for use or occupancy or that the facility is in condition to serve its intended purpose, but still may require minor miscellaneous work and adjustment. GC -6 2. 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 the Engineer. The Engineer will advise and consult with the Owner, and all of the 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 with the progress of the executed work and to determine if such work 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 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 responsible or liable for any acts, errors, omissions or negligence of the Contractor, 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 the Contractor's applications for payment and supporting data, determine the amount owed to the Contractor and recommend, in writing, payment to the Contractor in such amounts; such recommendation of payment to the Contractor constitutes a representation to the Owner of the Engineer's professional judgement that the work has progressed to the point indicated to the best of his knowledge, information and belief, but such recommendation of an application for payment to the Contractor shall not be deemed as a representation by the Engineer that the Engineer has made any examination to determine how or for what purpose the Contractor has used the monies 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 execution or progress of the work or interpretation of the Contract Documents. The Engineer's decision shall be rendered in GC -7 writing within a reasonable time, which shall not be construed to be less than ten (10) days. 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 (30) days his written objection to the decision, and by such action may reserve the right to submit the question so raised to litigation 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 reasonable 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 the 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 and 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 the Contractor to deviate from the plans and specifications; the intent of such drawings, specifications and any other GC -8 such information being to define with specificity the agreement of the parties as to the work the Contractor is to perform. The 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 the 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 drawings for temporary construction or construction processes, or by other means or methods, 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 the 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 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 the 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. The Contractor agrees that he will make no claim against the Owner or the Engineer if, in the prosecution of the work, he finds that the actual site or subsurface conditions encountered do not conform to those indicated by excavation, test excavation, test procedures, borings, explorations or other subsurface excavations. No verbal agreement or conversation with any officer, agent or employee of the Owner or the 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 Workers The Contractor agrees to employ only orderly and competent workers, skillful in the GC -9 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 workers on the work are, in his opinion, incompetent, unfaithful or disorderly, or refuse instructions from the Engineer in the absence of the Superintendent, such worker 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 workers, 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 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 (4) 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 promptness, making desired corrections. The Contractor shall make any corrections required by the Engineer, file with him two (2) corrected copies and furnish such other copies as may be needed. The Engineer's review 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 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 general conformity of said shop 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 GC -10 adequacy of such drawings or schedules, or any means or methods reflected thereby, in relation to the safety of either person or property during the 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 limitation, the obligation to at once tear out, remove and properly replace any defective work or material 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 the 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 GC -11 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 the event the Owner makes 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 compensate the Contractor for any material or labor so used, and for any actual loss occasioned by such change, due to actual expense incurred in preparation for the work as originally planned. 2.16 Inspectors The Engineer may provide one (or more) field inspectors at the work site for the limited purpose of 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 the Engineer and the Contractor their respective reports, opinions, questions, answers and clarifications concerning the plans, specifications and work but shall not be deemed the agent of the Contractor for all purposes in communicating such matters. Such inspectors may confer with the Contractor or the Contractor's Superintendent concerning the prosecution of the work and its conformity with the plans and specifications but shall never be, in whole or part, responsible for or 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 Engineer or the Owner to independently act for either or answer on behalf of either, any inquiries of the Contractor 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 or methods or manner of the Contractor's performance of work in progress or completed, or discovery or failure to discover or object to defective work of materials shall release the Contractor from his duty to complete all work in strict accordance with the plans and specifications or stop the Owner or the Engineer from requiring that all work be fully and properly performed including, if necessary, removal of defective or otherwise unacceptable work and the re -doing of such work. GC -12 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 (1) copy of the same constantly 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 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 that 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 at 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 the 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 so as not to unreasonably delay the progress of the work or damage the Contractor, except where such delays are specifically mentioned elsewhere in the Contract Documents. The Owner will attempt to coordinate the collateral work of utility 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. GC -13 3.06 Discrepancies and Omissions The Contractor shall provide written notice to the Engineer of any omissions or discrepancies found in the contract. 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 generally accepted practices for construction. 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 what 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. 3.08 Damages In the event the Contractor is damaged in the course of completion of the work by the act, negligence, omission, mistake or default of the Owner or the 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. All 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. In the event there is an accident involving injury to any individual on or near the work, GC -14 the Contractor shall immediately notify the Owner and the Engineer of the event and shall be responsible for recording the location of the event and the circumstances surrounding the event through photographs, interviewing witnesses, obtaining of medical reports and other documentation that defines the event. Copies of such documentation shall be provided to the Owner and the Engineer for their records. 3.10 Performance and Payment Bonds Unless otherwise specified, it is further agreed by the parties to the 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, on standard forms for this purpose, guaranteeing faithful performance of the work and the fulfillment of any guarantee required, and further guaranteeing payment to all persons supplying labor and materials or furnishing him any equipment in the execution of the contract. If the contract price is $25,000.00 or less, no payment or performance bond shall be required. It is agreed that the contract shall not be in effect until such performance and payment bonds are furnished and approved by the Owner. Unless otherwise specified, the cost of the premium for the performance and payment bonds shall be included in the price bid by the Contractor for the work under this contract, and no extra payment for such bonds will be made by the Owner. Unless otherwise approved in writing by the Owner, the surety company underwriting the bonds shall be licensed to write such bonds in the State of Texas. 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 the 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 GC -15 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 Subcontractors, Laborers, Materialmen and Furnishers of Machinery, Equipment and Supplies The Contractor agrees that he will indemnify and save the Owner and the Engineer harmless from all claims growing out the lawful demands of Subcontractors, laborers, workers, 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 to do so, then the Owner may either pay directly any unpaid bills of which the Owner has written notice, or may withhold from the Contractor's unpaid compensation a sum of money deemed reasonably sufficient to liquidate any and all such lawful claims. When satisfactory evidence is famished that all liabilities have been fully discharged, 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.

WR1001 July 1997 Applicable wage rates are shown in Section 06 WAGE RATES of the SPECIAL CONDITIONS. 4. 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 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. 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 the Engineer, or of any employee of either, or by other contractors employed GC -24 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. Adverse weather conditions will not be justification for extension of time on "Calendar Days" contracts. 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 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 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 twenty percent (20 %) more than, or twenty percent (20 %) less than the estimated GC -25 or contemplated quantity for such items, then either party to this agreement, upon demand, shall be entitled to revised consideration upon the portion of the work above or below twenty percent (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 that five percent (5 %) 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 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. 5.04 Partial Payments On or before the first 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 statement shall also include the value of all sound materials delivered on the job site and to be included in the work and 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 20th day of the current month the total amount of the approved statement, less five percent (5 %) of the amount thereof, which five percent (5 %) shall be retained until final payment, and further less all previous payments and all further sums that may by 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, then the Owner may, upon written recommendation of the Engineer, pay a reasonable and equitable portion of the retained percentage to the Contractor; or the Contractor, at the Owner's option, may be relieved of the obligation to fully complete the work and, thereupon, the Contractor shall receive payment of the balance due him under the contract subject only to the conditions stated under "Final Payment ". GC -26 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. 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 or delays the work, the Contractor shall be entitled to such extra compensation, 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 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 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 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 is found to be completed in accordance with the Contact 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 to issue a Certificate of Acceptance to the Contractor 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 measurements and 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 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 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 GC -27 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 the Owner or another contractor's work, material or equipment. 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 completed within the contract time. g) Other causes affecting the performance of the contract. 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 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 percent (6 %) per annum, unless otherwise specified, from date due as provided under "Partial Payments" and "Final Payment," 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 hereunder. 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. GC -28 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 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 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 methods: Method (A) By agreed unit prices; or Method (B) By agreed lump sum; or Method (C) If neither Method (A) nor Method (B) is agreed upon before the extra work is commenced, then the Contractor shall be paid the "actual field cost" of the work, plus fifteen percent (15 %). In the event said extra work is 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 foremen, 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 GC -29 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 workers' compensation, and all other insurance as may be required by any law or ordinance, or directed or agreed to by the Owner. 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 the 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 one hundred percent (100 %), 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 percent (15 %) 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 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 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 provided under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to mediation or litigation. 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 mediation 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 GC -30 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 Continuing Performance The Contractor shall continue performance of the contract during all disputes or disagreements with the Owner. The production or delivery of goods, the furnishing of services and the construction of projects or facilities shall not be delayed, prejudiced or postponed pending resolution of any disputes or disagreements, except as the Owner may otherwise agree in writing. 7. Abandonment of Contract 7.01 Abandonment by Contractor In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after written notification from the 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 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 herein), 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 the Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to the Contractor, and expense so charged shall be deducted and paid by the Owner out of such GC -31 monies 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 the 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 the 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 therefor. 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 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 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 GC -32 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 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. 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 acceptance 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 objection to any Subcontractor on such list and does not accept him. Failure of the Owner or the Engineer to make objection promptly to any Subcontractor 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 designated, with any Subcontractor proposed for the principal portions of the work who has been rejected by the Owner and the Engineer. GC -33 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 the Engineer refuses to accept any Subcontractor or person or organization on a list submitted 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. 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 Subcontractors and Sub - subcontractors) which shall contain provisions that: (1) preserve and protect the rights of the Owner and the 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 Documents; (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 GC -34 (5) Contractor upon the Owner; 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 completed, 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 monies to such Subcontractor except as may otherwise be required. 9.

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 to so 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, if he will so settle. If such separate contractor sues the Owner or initiates an proceeding allowed hereunder 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 costs or other 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 complete his work, except as otherwise specifically provided in the Contract Documents.

The type of material shall be selected from the following table: (2) Water Water shall be furnished by the Contractor and shall be clean and free from industrial wastes and other objectionable matter. 307 4/17/66 Page 1 Tack Coat Sieve Size Percent Retained by Weight Natural Sand No. 8 0 No. 16 0-40 No. 30 25 -65 No. 50 65 -85 No. 100 85 -98 No. 200 98 -100 (3) Sand Sand may be Grade 1 conforming to Item No. 403, "Concrete Structures" or washed sand, largely siliceous, with the following gradation: There shall not be more than 50 percent of the aggregate retained between any 2 sieves listed above and not more than 25 percent of the aggregate retained between No. 50 and No. 100 sieve. 307.3 Construction Methods 1 1 1 1 1 1 1 1 1 1 1 Tack coat shall not be applied when the air temperature is below 60 F and falling, but it may be applied when the air temperature is above 50 F and rising, the air temperature being taken in the shade and away from artificial heat. Asphaltic material shall not be placed when general weather conditions, in the opinion of the Engineer, are not suitable. Before the tack coat is applied, the surface shall be cleaned thoroughly to the satisfaction of the Engineer. The asphaltic material shall be applied on the clean surface by an approved type of self - propelled pressure distributor, so operated as to distribute the tack coat at a rate not to exceed 0.10 gallon per square yard of surface, evenly and smoothly under a pressure for proper distribution. Where the pavement mixture will adhere to the surface on 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 cleaned thoroughly and painted with a thin uniform coat of the asphaltic material used for tack coat. The tack coat shall be rolled with a pneumatic tire roller to distribute the asphaltic material uniformly over the tacked area. During the application of tack coat, care shall be taken to prevent splattering of adjacent pavement, curb and gutters or structures. The Contractor shall clean splattered areas. The distributor shall have been recently calibrated and the Engineer shall be furnished an accurate and satisfactory record of such calibration. After beginning of the work, should the yield on the asphaltic material applied appear in error, the distributor shall be calibrated in a manner satisfactory to the Engineer before proceeding with the work. 307 4/17/86 Page 2 Tack Coat 1 1 The Contractor shall be responsible for the maintenance of the surface until the HMAC is placed over the tack coat or the work is accepted by the Engineer. No traffic, hauling or placement of any subsequent courses shall be permitted over the freshly applied prime coat unless it is blotted by the application of sand as directed by the Engineer. All storage tanks, piping, retorts, booster tanks and distributors used in storing or handling asphaltic material shall be kept clean and in good operating condition at all times and they shall be operated in such a manner that there will be no contamination of the asphaltic material with foreign material. It shall be the responsibility of the Contractor to provide and maintain in good working order a recording thermometer at the storage heating unit at all times. The Engineer will select the temperature of application based on the temperature - viscosity relationship that will permit application of the asphalt within the limits recommended in Item No. 301, "Asphalts, Oils and Emulsions ". The recommended range for the viscosity of the asphalt is 100 to 125 centistokes. The Contractor shall apply the asphalt at a temperature within 15 F of 160 F. 307.4 Measurement The asphaltic material for "Tack Coat" will be considered subsidiary to Item 340, "Hot Mix Asphaltic Concrete Pavement" unless included as a separate pay item in the contract. When included for payment, "Tack Coat" shall be measured at point of delivery on the project in gallons at the applied temperature. The quantity to be paid for shall be the number of gallons used. 307.5 Payment The work performed and materials furnished as prescribed by this item, when included as a contract pay Item, will be paid for at the unit price bid per gallon for "Tack Coat ", which price shall be full compensation for cleaning the area to receive the "Tack Coat"; for fumishing, heating, hauling and distributing the tack coat specified; for all freight involved and for all manipulations, labor, tools, equipment and incidentals necessary to complete the work. Payment, when included as a contract pay item, will be made under: Pay Item No. 307: Tack Coat - Per Gallon.

Machines capable of removing, in one pass, a depth greater than 1 inch will be permitted. The equipment shall be self propelled with sufficient power, traction and stability to maintain accurate depth of cut. The machine shall be equipped with an integral loading and reclaiming means to immediately remove material being cut from the surface of the roadway and discharge the cuttings into a truck, all in one operation. Adequate backup equipment (mechanical street sweepers, loaders, water truck, etc.) and personnel will also be provided to keep flying dust to a minimum and to insure that all cuttings are removed from the street surface daily. Stockpiling of planed material will not be permitted on the project site. The machine shall be equipped with means to control dust created by the cutting action and shall have a system providing for uniformly varying the depth of cut while the machine is in motion, thereby making it possible to cut flush to all inlets, manholes, valves or other obstructions within the area to be milled. Any machine that is incapable, in the opinion of the Engineer, of meeting these requirements will not be permitted to be used. Various machines may be permitted to make trial runs to demonstrate the capabilities of that machine and to determine the acceptability of that machine to the Engineer. 315.3 Construction Methods The pavement surface shall be removed to a depth of 1 inch below the lip gutter transitioning to the existing surface in 3 feet or as indicated for resurfacing operations. When milling is used for leveling without the addition of asphalt, the milled surface shall be free of ridges deeper than 3/16 inch. The loose material resulting from the operation shall be disposed of at the Townview Yard (630 Harold Court) or other areas designated by the Engineer in writing.

(4) Stability and Density: The mixture shall be designed at or near optimum density as indicated. The laboratory mixture shall be molded in accordance with TxDOT Test Method TEX -206 -F and the Bulk Specific Gravity determined in accordance with TxDOT Test Method TEX -207 -F with the following percent of Maximum Theoretical Density as measured by TxDOT Test Method TEX -227- F and Stability conforming to TxDOT Test Method TEX- 208 -F: Job Mix Formula Field Adjustments: The Contractor shall produce a mixture of uniform composition closely conforming to the reviewed JMF within the limits of the tolerances given above and the Acceptance Plan. If it is determined by the City's laboratory that adjustments to the JMF are necessary to achieve the specified requirements, the Engineer may allow adjustments of the JMF within the following limits without a laboratory redesign of the mixture. The adjusted JMF shall not exceed the master grading for the type of mixture specified nor shall the adjustments exceed 5 percent on any one sieve, '/z inch size and larger, or 3 percent on the sieve size below the Yz inch sieve of the JMF (Plant Corrected) reviewed for the Project. When the considered adjustments exceed either the 5 or 3 percent limits, and the Engineer determines that the impact of these changes may adversely affect pavement performance, a new laboratory mixture design will be required. 340 8/23/96 Page 7 Hot Mix Asphaltic Concrete Pavement (5) (5) 340.4 Equipment All equipment used for the production, placement and compaction of the mixture shall be maintained in good repair and operating conditions to the satisfaction of the Engineer. All equipment shall be made available for inspection. Any equipment shall not be used until it is repaired to the satisfaction of the Engineer. Mixing Plants: Plants may be of the weigh -hatch or drum -mix type equipped with suitable material conveyers, aggregate proportioning devices, dryers, bins, dust collectors and sensing and recording devices as appropriate for the mixing plant type. (2) Spreading and Finishing Paving Machine: The paving machine shall be self- propelled and equipped with a heated screed capable of producing a finish surface meeting the requirements of the street cross - section specified on the Drawings and all surface tests. Extensions to the screed shall have the same heating and vibratory capabilities as the primary unit. The paving machine shall be equipped with an automatic dual longitudinal screed control system and a transverse screed control system. The longitudinal controls shall be capable of operating from any longitudinal grade reference including a stringline, ski, mobil stringline or matching shoe. Unless otherwise shown on the Drawings, the Contractor may use any one of these grade references. The Contractor shall fumish all labor and equipment required for grade reference. (3) Rollers: The Contractor shall select rollers conforming to Item 230, "Rolling (Flat Wheel)" and Item 232, "Rolling (Pneumatic Tire) ". Rollers not conforming to these requirements shall be immediately removed from the Project. (4) Motor Grader: A self - propelled motor grader may be used only when its use is approved by the Engineer. It shall have a blade of not less than 12 feet and a wheelbase of not less than 16 feet. Smaller graders may be used for small irregular areas when approved by the Engineer. Material Transfer Equipment: Equipment to transfer mixture from the hauling units or the roadbed to the spreading and finishing machine will be allowed unless otherwise shown on the Drawings. Windrow pick -up equipment, if permitted, shall be constructed in such a manner that substantially all of the mixture deposited on the roadbed is picked up and loaded into the spreading and finishing machine. The loading equipment shall be designed so that it does not interfere with the spreading and finishing machine in obtaining the required line, grade and surface without resorting to hand finishing. (6) Straightedge: The Contractor shall provide a ten foot straightedge acceptable to the Engineer for surface testing. ( The asphalt content may be adjusted as concurred by the Engineer to maintain desirable laboratory density near the optimum value while achieving other mix requirements. However, increasing the asphalt content of the mixture in order to reduce pavement air voids will not be allowed. Also, if the percent air voids is determined to be less than 4 percent, adjustments shall be made to the plant production by the Contractor, within the tolerances as outlined above so that an adequate air void level results. 340 8123196 Page 8 Hot Mix Asphaltic Concrete Pavement 340.5 Stockpiling Aggregates Aggregates shall be stockpiled to facilitate blending. If the aggregate is not stockpiled on a hard, non - contaminant base, the bottom six inch layer of the stockpiles shall not be used. Where space is limited, stockpiles shall be separated by walls or other appropriate barriers. Aggregate shall be stockpiled and protected from the weather a minimum of 24 hours prior to use to minimize free moisture content. When stockpiles are too large to protect from the weather, accurate and continuous means acceptable to the Engineer shall be provided to monitor aggregate moisture. Aggregates shall be stockpiled and handled such that segregation and contamination are minimized. No stockpile shall contain aggregate, including RAP, from more than one source. 340.6 Mixture Temperature The Contractor shall select a target temperature for discharge from the mixer between 250 F and 350 F for the mixture suitable to weather and Project conditions. The target temperature shall be reported to the Engineer daily and recorded in the Daily Progress Report. The mixture temperature shall not vary by more than 25 F from the target temperature upon discharge from the mixer. No mixture cooler than 50 F from target temperature shall be accepted or placed on the Project. 340.7 Mixture Storage A surge - storage system may be used to minimize production interruptions during the normal days operations. When approved by the Engineer, overnight storage in insulated storage bins may be used provided that material temperature and physical properties are not adversely affected. Mixtures with hardened lumps shall not be used. Stored mixtures shall not be exempt of any requirements provided in this specification. When a surge- storage system is used, it shall be equipped with a device such as a gob hopper or other device approved by the Engineer to prevent segregation in the surge- storage bin. 340.8 Mixture Moisture Content Mixture produced from any plant shall not have a moisture content in excess of ah percent by weight when discharged from the mixer. The moisture content shall be determined in accordance with TxDOT Test Method Tex - 212 -F, Part II, except that the sample shall be left in the oven a total of not less than four (4) hours. 340.9 Construction Methods (1) General: The Contractor shall be responsible for the production, transportation, placement and compaction of the specified paving mixture to the requirements of this specification. The Contractor shall also be responsible for providing a safe environment for inspection personnel to inspect the equipment and to take samples. 340 8/23/96 Page 9 Hot Mix Asphaltic Concrete Pavement Any material delivered to the Project that by visual inspection can reasonably be expected not to meet specification requirements (i.e. segregated or bumed material, deficient or excess asphalt, low mixing temperature, visible contaminants, etc.), as determined by the Engineer, shall not be used or left in place. Equipment shall be inspected prior to use and, if found to be defective or in an operating condition that could potentially affect the quality of the finished pavement, as determined by the Engineer, its use shall not be allowed. Leakage of fuels, oils, grease, hydraulic or brake fluids or other contaminants onto the prepared surface or newly -laid mat will not be allowed. The paving mixture, when placed with a spreading and finishing machine, shall not be placed when the air temperature is below 50 F and is falling, but it may be placed when the air temperature is above 40 F and rising. The paving mixture, when used as a level -up course or when placed with a motor grader, shall not be placed when the air temperature is below 60 F and is falling, but it may be placed when the air temperature is 50 F and rising. 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. The temperature shall be taken in a shaded area away from artificial heat. Surfaces to be paved shall be finished, primed, cured, broomed and tacked, as appropriate, to the satisfaction of the Engineer. If the surface on which the first course of the paving mixture is to be placed is a flexible base course, and a cut -back asphalt is to be used as a prime coat, the flexible base shall have been primed and cured a minimum of 24 hours before the paving mixture may be placed. The 24 hour restriction will not apply to a flexible base that has been primed with material other than a cut -back. However, the surface on which the tack coat and /or paving mixture Is to be placed shall be in a dry condition. Pavement shall be opened to traffic as soon as possible after temporary pavement markings or permanent markings are in place as indicated or as directed by the Engineer. Construction traffic allowed on pavements open to the public will be subject to all laws governing traffic on streets and highways. (2) Tack Coat: The surface upon which the tack 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 as governed by Item 307, 'Tack Coat". The tack coat shall be applied with an approved sprayer at a rate not to exceed 0.05 gallons per square yard. Where the paving mixture will adhere to the surface on 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, castings and structures shall be painted with a thin uniform application of tack coat. Whenever cut -back asphalts are used as a tack coat, the tack coat shall be rolled with a pneumatic roller. During the application of tack coat, care shall be taken to prevent splattering of adjacent pavement, curb and gutter and structures. All splatter shall be removed by the Contractor at his expense before the Work can be accepted. (3) Transporting Asphaltic Concrete: The asphaltic mixture shall be hauled to the Work site in tight vehicles previously cleaned of all foreign material. In cool weather or for long hauls, covering of the truck bodies is required. 340 8/23196 Page 10 Hot Mix Asphaltic Concrete Pavement (4) Placing: Placing of the asphaltic mixture shall be done without tearing, shoving, gouging or segregating the mixture and without producing streaks in the mat. Unloading into the finishing machine shall be controlled so that bouncing or jarring the spreading and finishing machine shall not occur and the required lines and grades shall be obtained without resorting to hand finishing except as permitted below in this Section. Unless otherwise shown on the Drawings, dumping of the asphaltic material in a windrow and then placing the mixture in the finishing machine with windrow pick -up equipment will be permitted provided the temperature of the asphaltic mixture does not drop more than 50 F below the target temperature before being placed by the finishing machine. Under no circumstances will the asphaltic material be permitted to be dumped on or near the job site and then reloaded for hauling to the site of placement. Exceptions may be allowed if approved by the Engineer. When approved by the Engineer, level -up courses may be spread with a motor grader meeting the requirements of this specification. The spreading and finishing machine shall be operated at a uniform forward speed consistent with the plant production rate, hauling capability and roller train capacity to result in a continuous operation. Stopping of the spreading and finishing machine between trucks is to be held to a minimum. If, in the opinion of the Engineer, delivery of material is adversely affecting the mat (excessive stopping of the spreading and finishing machine, loss of mixture temperature, etc.), the Engineer may require paving operations to cease until acceptable methods are provided to minimize starting and stopping of the spreading and finishing machine. The hopper gates of the spreading and finishing machine shall be adjusted to provide an adequate and consistent flow of material. This shall result in enough material being delivered to the augers so that they are operating approximately 85 percent of the time or more. The augers shall provide means to supply adequate flow of material to the center of the paver. Augers shall supply an adequate flow of material for the full width of the mat being placed. Augers should be kept approximately one -half to three- quarters full of mixture at all times during the paving operation. When the asphaltic mixture is placed in a narrow strip along the edge of an existing pavement, or used to level up small areas of an existing pavement or placed in small irregular areas where the use of a finishing machine is not practical, the finishing machine may be eliminated when permitted by the Engineer. The paving material adjacent to castings and curb and gutter shall be finished uniformly high so that when compacted, it will be slightly above but not more than 1/8 inch above the edge of the casting or gutter hp. Longitudinal joints in the mat shall be placed to coincide with lane lines. Transverse joints shall be offset a minimum of five (5) Feet. (5) Compacting: The pavement shall be compacted thoroughly and uniformly to obtain the compaction and cross section meeting the requirements of the Drawings and specifications. Regardless of the method used for compaction, all rolling for compaction shall cease before the mixture drops below 175 F. 340 8/23/96 Page 11 Hot Mix Asphaltic Concrete Pavement Rolling with a pneumatic tire roller to seal the surface shall be provided. Rolling with a tandem or other steel -wheel roller shall be provided if required to iron out any roller marks. Vibratory rollers shall not be allowed in the vibrating mode on mats with a plan depth of less than 11/2 inches. 340.10 Sampling and Testing The asphalt mixture shall be tested daily at the Project site for conformance to specification requirements. The Engineer shall determine sample locations based on the Contractor's anticipated production and the random number method of TxDOT Test Method Tex - 225 -F. Each days anticipated production shall be sectioned into three (3) equal single -pass, sub -area lots. Each day's sample locations shall be equally distributed over the three (3) sub - areas. If, due to the weather or plant malfunctions, the Contractor's daily anticipated production is not made, the random locations will not be recalculated. Also, no more than one location of the three (3) sub -areas is to be located in an irregular shaped area such as a cul-de -sac. Unless otherwise approved by the Engineer, a minimum of three bag samples and three correlating cores will be obtained from each days production. Bag samples shall be taken during lay -down operations. The primary sampling point for the bag samples shall be from the windrow if a windrow elevator is used. If a windrow elevator is not used, the sample shall be taken from the middle of the paving machine hopper. This will require stopping the paving machine in order for the Inspector to safely secure a sample by digging into the hopper. Gradation, asphalt content and stability shall be reported for each of the bag samples. The stability value reported for each of the bag samples shall be the average of three (3) tests per bag. Pavement thickness and density shall be determined by 6 -inch cores. One core shall be taken for every 2,000 single -pass square yards with a minimum of three (3) cores for all projects. One core shall be taken at the same station and pass sampled for each of the bag samples. For each day's placement, density of cores for which no corresponding bag samples were taken shall be determined by using the average Maximum Theoretical Density of the day's three (3) bag samples or as may otherwise be determined by the Engineer. The Engineer may alter, increase or waive the testing schedule to ensure material and workmanship compliance with specificatioh requirements. Acceptability of the completed pavement shall be based on the average of test results for the Project as defined in Article 340.11, "Acceptance Plan ". For total areas of less than 500 square yards, a total of only two bag samples and two correlating cores will be obtained. If the Contractor desires additional testing, it shall be at his entire expense. When, in the opinion of the Engineer, test results appear unrepresentative, additional testing may be authorized. The retesting will be at the expense of the Contractor and the results of the retesting shall be averaged with the results of the original testing. If the results of retesting indicate that the original testing was erroneous, the original test results will be discarded. Pavements with low density results may be recored; but, the pavement shall not receive any additional compactive effort. Cores shall be taken by the City's laboratory within 48 hours of paving unless otherwise authorized by Engineer. Pavements that will not or can not be cored within 48 hours shall be closed to both public and construction traffic. 340 8/23/96 Page 12 Hot Mix Asphaltic Concrete Pavement 340.11 Acceptance Plan For the purpose of the Acceptance Plan only, the 'Project' shall be defined as follows: The Project is the quantity of each of the specified mixture types as determined by the Engineer before the paving operation begins. Considerations for defining the Project shall include paving operation staged due to traffic considerations, changes to the Job Mix Formula, phasing of large projects, or other factors affecting the consistency in the production, lay- down /compaction, use of completed portions, and /or aging of in -place material. Acceptability of the completed pavement shall be based on the average of a minimum of three tests per Project for each of the mixture types specified. Pay adjustments for two or more acceptance factors shall be accumulative. Pay adjustments of 100% unit price reduction shall require removal and replacement of the Work. Replacement materials shall be subject to all requirements of this specification. Altematively, the Engineer may allow the Work to remain In place without payment provided that the Work is warranted for an extended period and under conditions as determined by the Engineer. The decision of the Engineer as to the removal and replacement of the Work shall be the final authority. (1) Non - Pay - Adjustment Acceptance Factors: (a) Surface Characteristics: Unless otherwise directed by the Engineer, all pavements shall be tested for smoothness. Surfaces shall be tested with a 10 foot straightedge parallel to the roadway centerline and perpendicular to the centerline on flat, cross -slope sections. Maximum allowable deviation in 10 feet shall be 1/8 inch parallel to the centerline and % inch perpendicular to the centerline. Sections exceeding these maximums shall be corrected to the satisfaction of the Engineer. The completed surface must meet the approval of the Engineer for surface smoothness, finish and appearance. If the surface ravels, ruts or deteriorates in any manner prior to the end of the warranty period, it will be the Contractor's responsibility to correct this condition at his expense to the satisfaction of the Engineer and in conformance with the requirements of this specification. For HMAC rehabilitation and overlay projects, if cracks develop in the pavement surface within the one year warranty period, the Contractor shall seal the cracks in accordance with Item 313, "Rubber Asphalt Joint and Crack Sealer". Payment for this work will be measured and paid for as Mobilization (LS) and Crack Sealing (LF).
