The fact that the specifications may fail to be sufficiently complete in some detail will not relieve the Contractor of full responsibility for providing materials of high quality and for protecting them adequately until incorporated into the project. The presence or absence of a representative of the City on the site will not relieve the Contractor of full responsibility of complying with this provision. The specifications for materials and methods set forth in the contract documents provide minimum standards of quality, which the Owner believes necessary to procure a satisfactory project. 16 GUARANTEES 16.1 All equipment and materials incorporated in the project and all construction shall be guaranteed against defective materials and workmanship. Prior to final acceptance, the Contractor shall furnish to the Owner, a written general guarantee which shall provide that the Contractor shall remedy any defects in the work, and pay for any and all damages of any nature whatsoever resulting in such defects, when such defects appear within ONE year from date of final acceptance of the work as a result of defective materials or workmanship, at no cost to the Owner (City of Lubbock). 16.2 Notwithstanding any provisions contained in the contractual agreement, the Contractor represents and warrants fault -free performance and fault -free result in the processing date and date -related data r� (including, but not limited to calculating, comparing and sequencing) of all hardware, software and firmware products delivered and services provided under this Contract, individually or in combination, as the case may be from the effective date of this Contract. Also, the Contractor warrants calculations will be recognized and accommodated and will not, in any way, result in hardware, software or firmware failure. The City of Lubbock, at its sole option, may require the Contractor, at any time, to demonstrate the procedures it intends to follow in order to comply with all the obligations contained herein. 16.3 The obligations contained herein apply to products and services provided by the Contractor, its sub- contractor or any third party involved in the creation or development of the products and services to be delivered to the City of Lubbock under this Contract. Failure to comply with any of the obligations contained herein, may result in the City of Lubbock availing itself of any of its rights under the law and under this Contract including, but not limited to, its right pertaining to termination or default. 16.4 The warranties contained herein are separate and discrete from any other warranties specified in this Contract, and are not subject to any disclaimer of warranty, implied or expressed, or limitation to the Contractor's liability which may be specified in this Contract, its appendices, its schedules, its annexes or any document incorporated in this Contract by reference. 17 PLANS FOR THE CONTRACTOR The contractor will be furnished one set of plans and specifications, and related contract documents for his use during construction.

PROTECTION OF SUBSURFACE LINES AND STRUCTURES It shall be the Contractor's responsibility to prosecute the work contemplated by the contract documents in such a way as to exercise due care to locate and prevent damage to all underground pipelines, utility lines, conduits or other underground structures which might or could be damaged by Contractor during the construction of the project contemplated by these contract documents. The City of Lubbock agrees that it will furnish Contractor the location of all such underground lines and utilities of which it has knowledge. However, such fact shall not relieve the Contractor of his responsibilities aforementioned. All such underground lines or structures cut or damaged by Contractor during the prosecution of the work contemplated by this contract shall be repaired immediately by Contractor to the satisfaction of the City of Lubbock, Texas, at Contractor's expense. BARRICADES AND SAFETY MEASURES The contractor shall, at his own expense, furnish and erect such barricades, fences, lights and danger signals, and shall take such other precautionary measures for the protection of persons, property and the work as may be necessary.

Such notice, however, shall not relieve the Contractor of responsibility for any damage resulting from his blasting operations. CONTRACTOR'S REPRESENTATIVE The successful bidder shall be required to have a responsible local representative available at all times while the work is in progress under this contract. The successful bidder shall be required to furnish the name, address and telephone number where such local representative may be reached during the time that the work contemplated by this contract is in progress. 24 INSURANCE 24.1 The Contractor shall not commence work under this contract until he has obtained all insurance as required in the General Conditions of the contract documents, from an underwriter authorized to do business in the State of Texas and satisfactory to the City.

The bidders' attention is further directed to the requirements of Article 5159a, Vernon's Annotated Civil Statutes providing for the payment of the wage schedules above mentioned and the bidder's obligations thereunder. The inclusion of the schedule of general prevailing rate of per diem wages in these contract documents does not release the Contractor from compliance with any wage law that may be applicable.

When Owner so desires, the Contractor shall furnish *— satisfactory evidence that all obligations of the nature hereinabove designated have been paid, discharged or waived. If during the progress of the work, Contractor shall allow any indebtedness to accrue for work furnished by any of those designated in the preceding paragraph and shall fail to pay and discharge any such indebtedness within five (5) days after demand is made, then Owner may, during the period for which such indebtedness shall remain unpaid, in addition to any statutory retainage rights it may have, withhold from the unpaid portion of this contract, a sum equal to the amount of such unpaid indebtedness or may apply the sum so withheld to discharge any such indebtedness. P" 31. PROTECTION AGAINST ROYALTIES OR PATENT 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 letters patent or copyright by suitable legal agreement with the Patentee or owner thereof. Without limiting, in any way, manner or form, the indemnity provided by Contractor in paragraph 27 hereof, the Contractor shall defend all suits or claims for infringement of any patent or copyrights and shall indemnify and save the Owner, and all of its officers, agents and employees harmless from any loss on account *" thereof, except that Owner shall defend all such suits and claims and shall be responsible for all such loss when a particular design, device, material or process or the product of a particular manufacturer or manufacturers is specified or required in these contract documents by Owner; provided, however, if choice of alternate design, device, material or process is allowed to the Contractor, then Contractor shall indemnify and save Owner, and all of its officers, agents and employees harmless from any loss on account thereof. Notwithstanding anything herein to the contrary, if the material or process specified or required by Owner and/or this contract is an infringement, the Contractor shall be responsible for such loss unless it gives written notice of such infringement to the Owner's Representative prior to bidding. 32. LAWS AND ORDINANCES The Contractor shall at all times observe and comply with all federal, state and local laws, ordinances and regulations, which in any manner affect the contract or the work, and without limiting, in any way, manner or form, the indemnity provided by Contractor in paragraph 27 hereof, Contractor shall indemnify and save harmless the Owner, and all of its officers, agents, and employees against any claims arising from the violation of any such laws, ordinances, and regulations, whether by the Contractor, its employees, or subcontractors. if the Contractor observes that the plans and specifications are at variance therewith, he shall notify the Owner's Representative in writing prior to bidding and any necessary changes shall be adjusted as provided in the contract for changes in the work. In the absence of timely written notification to Owner's Representative of such variance or variances within said time, any objection and%or assertion that the plans and specifications are at variance with any federal, state or local laws, ordinances or regulations shall be deemed waived. If the Contractor, its employees or subcontractors perform any work contrary to such laws, ordinances, rules and regulations, and without such notice to the Owner's Representative, Contractor shall bear all costs arising therefrom. The Owner is a municipal corporation of the State of Texas and the law from which it derives its powers, insofar as the same regulates the objects for which, or the manner in which, or the conditions under which the Owner may enter into contracts, shall be controlling, and shall be considered as part of this contract to the same effect as though embodied herein. 33. SUBCONTRACTING_ - The Contractor agrees that it will retain personal control and will give its personal attention to the fulfillment of this contract. The Contractor further agrees that subletting of any portion or feature of the work, or materials required 13 in the performance of this contract, shall not relieve the Contractor from its full obligations to the Owner, as provided by the contract documents. 34. TIME FOR SUBSTANTIAL COMPLETION AND LIQUIDATED DAMAGES It is hereby understood and mutually agreed by and between the Contractor and the Owner, that the date of beginning and time for completion as specified in the contract documents, of work to be done hereunder are essential conditions of this contract; and it is further mutually understood and agreed that the work embraced in this contract shall be commenced as provided in the contract documents. If the Contractor should neglect, fail, or refuse to substantially complete the work within the time herein specified, then the Contractor does hereby agree as part of the consideration for the awarding of this contract, the Owner may withhold permanently from Contractor's total compensation, the sum of $250.00 (TWO HUNDRED FIFTY DOLLARS) PER DAY, not as a penalty, but as liquidated damages for the breach of the contract as herein set forth for each and every working day that the Contractor shall be in default after the time stipulated for substantially completing the work. It is expressly understood and agreed, by and between Contractor and the Owner, that the time for the substantial completion of the work described herein is reasonable time for the completion of the same, taking into consideration the average climatic range and conditions and usual industrial conditions prevailing in this locality. The amount is fixed and agreed upon by and between the Contractor and the Owner because the actual damages the Owner would sustain in such event would be difficult and/or impossible to estimate, however, the amount agreed upon herein is a reasonable forecast of the amount necessary to render just compensation to Owner, and is expressly agreed to be not disproportionate to actual damages as measured at time of breach. IT IS FURTHER AGREED AND UNDERSTOOD BETWEEN THE CONTRACTOR AND OWNER THAT TIME IS OF THE ESSENCE OF THIS CONTRACT. 35. 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 its work at such time and sessions, in such order of precedence, and in such manner as shall be most conductive to economy of construction; provided, however, that the order and time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications, and within the time of completion designated in the bid; provided, also, that when the Owner is having other work done, either by contract or by its own force, the Owner's Representative may direct the time and manner of constructing work done under this contract so that conflicts 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 Owner's Representative, schedules which shall show the order in which the Contractor intends 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. 36. TIME OF PERFORMANCE The Contractor agrees that it has submitted its bid in full recognition of the time required for the completion of this project, taking into consideration the average climatic range and industrial conditions prevailing in this locality, and has considered the liquidated damage provisions of paragraph 34 hereinabove set forth and expressly agrees that it shall not be entitled to, nor will it request, an extension of time on this contract, except when its work has been delayed by an act or neglect of the Owner, Owner's Representative, employees of the Owner or other contractors employed by the Owner, or by changes ordered in the work, or by strike, walkouts, acts of God or the public enemy, fire or flood. Any request for extension shall be in writing with the written request for same setting forth all justifications, in detail, for the request, and submitted to Owner's Representative within twenty (20) calendar days of the occurrence of the event causing said delay. A failure by Owner's Representative to affirmatively grant the extension no later than twenty (20) calendar days of written submission by Contractor shall be deemed a denial, 14 i and final. Further, in the absence of timely written notification of such delay and request for extension, as provided herein, any request for extension by Contractor shall be deemed waived. 37. HINDRANCE AND DELAYS In executing the contract, the Contractor agrees that in undertaking to complete the work within the time herein fixed, Contractor has taken into consideration and made allowances for all hindrances and delays incident to such work, whether growing out of delays due to unusual and unanticipated circumstances, difficulties or delays in securing material or workmen, or any other cause or occurrence. No charge shall be made by the Contractor for hindrance or delays from any cause during the progress of any part of the work embraced in this contract except where the work is stopped by order of the Owner or Owner's Representative for the Owner's convenience, in which event, such expense as in the sole judgment of the Owner's Representative that is caused by such stoppage shall be paid by Owner to Contractor. 38. QUANTITIES AND MEASUREMENTS No extra or customary measurements of any kind will be allowed, but the actual measured or computed length, area, solid contents, number and weight only shall be considered, unless otherwise specifically provided. In the event this contract is let on a unit price basis, then Owner and Contractor agree that this contract, including the specifications, plans and other contract documents are intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown, and only when same are expressly stated to be estimates, 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 their bids offered for the work. In the event the amount of work to be done and materials to be furnished are expressly stated to be estimated, and only when same are expressly stated to be estimated, it is understood and agreed that the actual amount of work to be done and the materials 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 work done and materials furnished on the project. 39. PROTECTION OF ADJOINING PROPERTY The Contractor shall take proper means to protect the adjacent or adjoining property or properties in any way encountered, which may 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 Contractor shall be liable for any and all claims for such damage on account of his failure to fully protect all adjacent property. Without limiting, in any way, manner and form, the indemnity provided by Contractor in paragraph 27 hereof, the Contractor agrees to indemnify, save and hold harmless the Owner, and any of its officers, agents and employees, against any and all claims or damages due to any injury to any adjacent or adjoining property, related to, arising from or growing out of the performance of this contract. 40. PRICE FOR WORK In consideration of the furnishing of all necessary labor, equipment and material and the completion of all work by m„ the Contractor, and on the delivery of all materials embraced in this contract in full conformity with the specifications and stipulations herein contained, the Owner agrees to pay the Contractor the price set forth in the bid proposal attached hereto, which has been made a part of this contract, and the Contractor hereby agrees to receive such price in full for furnishing all materials and all labor required for the aforesaid work, also, for all expenses incurred by Contractor and for well and truly performing the same and the whole thereof in the manner and according to this agreement, the attached specifications, plans, contract documents and requirements of Owner's Representative. 41. PAYMENTS No payments made or certificates given shall be considered as conclusive evidence of the performance of the contract, either wholly or in part, nor shall any certificate or payment be considered as acceptance of defective work. Contractor shall at any time requested during the progress of the work furnish the Owner or Owner's 15 Representative with a verifying certificate showing the Contractor's total outstanding indebtedness in connection with the work. Before final payment is made, Contractor shall satisfy Owner, by affidavit or otherwise, that there are no outstanding liens against Owner's premises by reason of any work under the contract. Acceptance by _ Contractor of final payment of the contract price shall constitute a waiver of all claims against Owner, Owner's agents and employees, which have not theretofore been timely filed as provided in this contract. 42. PARTIAL PAYMENTS On or before the tenth day of each month, the Contractor shall submit to Owner's Representative an application for partial payment or, if the Contractor does not submit such application, the Owner's Representative shall determine the amount to be partially paid. Owner's Representative shall review said application for partial payment if submitted, and the progress of the work made by the Contractor and if found to be in order, shall prepare a certificate for partial payment showing as completely as practical the total value of the work done by the Contractor up to and including the last day of the preceding month. The determination of the partial payment by the Owner's Representative shall be in accordance with Paragraph 14 hereof. The Owner shall then pay the Contractor on or before the fifteenth day of the current month the total amount of the — Owner's Representative's Certificate of Partial Payment, less 5% of the amount thereof, which 5% shall be retained until final payment, and further, less all previous payments and all further sums that may be retained by Owner under the terms of the contract documents. Any partial payment made hereunder shall not constitute a waiver by the Owner of any and all other rights to enforce the express terms of the contract documents, and all remedies provided therein, as to any and all work performed, to be performed and/or materials delivered hereunder, including, but limited to, work to which said partial payment is attributable. 43. SUBSTANTIAL COMPLETION Contractor shall give Owner's Representative written notice of substantial completion. Within thirty-one (31) working days after the Contractor has given the Owner's Representative written notice that the work has been substantially completed, the Owner's Representative and/or the Owner shall inspect the work and within said time, if the work be found to be substantially completed in accordance with the contract documents, the Owner's Representative shall issue to the Owner and Contractor a certificate of substantial completion. Notwithstanding the issuance of a certificate of substantial completion, Contractor shall proceed with diligence to finally complete the work within the time provided in this contract. 44. FINAL COMPLETION AND PAYMENT The Contractor shall give written notice to Owner's Representative of final completion. Upon written notice of final completion, the Owner's Representative shall proceed to make final measurement to determine whether final completion has occurred. If the Owner's Representative determines final completion has occurred, Owner's Representative shall so certify to the Owner. Upon certification by Owner's Representative of final completion, Owner shall pay to the Contractor on or before the 31 st working day after the date of certification of final completion, the balance due Contractor under the terms of this agreement. Neither the certification of final completion nor the final payment, nor any provisions in the contract documents shall relieve the Contractor of the obligation for fulfillment of any warranty which may be required in the contract documents and/or any warranty or warranties implied by law or otherwise. Contractor shall promptly remove from Owner's premises all materials condemned by the Owner's Representative on account of failure to conform to the contract documents, whether actually incorporated in the work or not, and Contractor shall at its own expense promptly replace such condemned materials with other materials conforming to the requirements of the contract documents. Contractor shall also bear the expense of restoring all work of other contractors damaged by any such removal or replacement. If Contractor does not remove and replace any 16 k. such condemned work within a reasonable time after a written notice by the Owner or the Owner's Representative, Owner may remove and replace it at Contractor's expense. Neither the final payment, nor certification of final completion or substantial completion, nor any provision in the contract documents shall relieve the Contractor of responsibility for faulty materials or workmanship, and Contractor shall remedy any defects due thereto and pay for any damage to other work resulting therefrom, which shall appear within a period of one (1) year from the date of certification of final completion by Owner's Representative. 46. PAYMENT WITHHELD The Owner or Owner's Representative may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certification to such extent as may be necessary to protect itself from loss on account of: (a) Defective work not remedied and/or work not performed. (b) Claims filed or reasonable evidence indicating possible filing of claims. (c) Failure of the Contractor to make payments promptly to subcontractors or for materials or labor. (d) Damage to another contractor. When the above grounds are removed, or the Contractor provides a surety bond satisfactory to the Owner, in the amount withheld, payment shall be made for amounts withheld because of them. 47. CLAIM OR DISPUTE 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 Owner's Representative within fifteen (15) calendar days after the Owner's .� Representative has given any direction, order or instruction to which the Contractor desires to take exception. Timely written notice of dispute as provided in this contract of any decision by Owner's` Representative or Owner shall be a condition precedent to the bringing and/or assertion of any action or claim by Contractor of any right under this Contract. If the matters set forth in the notice of dispute are not granted or otherwise responded to by Owner's Representative within fifteen (15) calendar days of receipt of notice of dispute by Owner's Representative, said objections shall be deemed denied. Any decision by the Owner's Representative, or deemed denial by the Owner's Representative, shall be final and conclusive in the absence of fraud. It is further agreed that the acceptance by the Contractor of the final payment shall be a bar to any and all claims of the Contractor, and constitute a waiver of the right to assert any claim against Owner, Owner's agents and employees and Owner's Representative, by Contractor. 48. NON-COMPLIANCE AND/OR ABANDONMENT BY CONTRACTOR In case the Contractor should (1) abandon and fail or refuse to resume work within fifteen (15) calendar days after written notification from the Owner or the Owner's Representative, or (2) if the Contractor fails to comply with the written orders of the Owner's Representative, when such orders are consistent with this contract, then the Surety on the bond shall be notified in writing and directed to complete the work and a copy of said notice shall be delivered to the Contractor. In the event a bond is not required by law, or otherwise obtained by the Contractor, no further notice of such non-compliance to Contractor shall be required. After receiving said notice of abandonment or non-compliance , 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 the contract for work, may be held for use on the work by the Owner or the Surety of the Contractor, or another contractor, in completion of the work; and the Contractor shall not receive any rental or credit therefore (except when used in connection with Extra Work, where credit shall be allowed as provided for under paragraph 24 of this contract); 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. 17 In the event the Contractor, or Surety, whichever is applicable, should fail to commence compliance with the notice hereinbefore provided within ten (10) calendar days after service of such notice, and/or shall fail to proceed with diligence to complete the project as contemplated and in compliance with all terms and provisions of the contract documents, then the Owner may exercise any and all remedies available to it pursuant to law, contract, equity or otherwise, including, but not limited to, providing for completion of the work in either of the following elective manners: (a) The Owner may employ such force of men and use of machinery, equipment, tools, materials and supplies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said Contractor, and the expense so charged shall be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, if the same had been completed by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said Contractor, then the Contractor and/or its Surety shall pay the amount of such excess to the Owner; or (b) The Owner, under sealed bids, after notice published as required by law, at least twice in a newspaper having a general circulation in the County of location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract. In case of any increase in cost to the Owner under the new contract as compared to what would have been the cost under this contract, such increase shall be charged to the Contractor and the Surety shall be and remain bound therefore. Should the cost to complete any such new contract prove to be less than that which would have been the cost to complete the work under this contract, the Contractor or his Surety shall be credited therewith. In the event the Owner's Representative elects to complete the work, as described above, when the work shall have been finally completed, the Contractor and his Surety shall be so notified and certification of completion as provided in paragraph 44 hereinabove set forth, shall be issued. A complete itemized statement of the contract accounts, certified to by Owner's Representative as being correct shall then be prepared and delivered to Contractor and his Surety, if applicable, whereon the Contractor or his Surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement within 30 days after the date of certification 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, if applicable, 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, if applicable. Should the cost to complete the work exceed the contract price, and the Contractor and/or his Surety, if applicable, 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, if applicable, 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, if applicable, subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) calendar 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, if applicable. Such sale may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any machinery, equipment, tools, materials, or supplies that remain on the jobsite and belong to persons other than the Contractor or his Surety, if applicable, to their proper owners. The remedies provided to Owner by law, equity, contract, or otherwise, shall be cumulative, to the extent permitted by law. It is expressly agreed and understood that the exercise by Owner of the remedies provided in this paragraph shall not constitute an election of remedies on the part of Owner, and Owner, irrespective of its exercise of remedies hereunder, shall be entitled to exercise concurrently or otherwise, any and all other remedies 18 available to it, by law, equity, contract or otherwise, including but not limited to, liquidated damages, as provided in paragraph 34, hereinabove set forth. r" 49. LIMITATION ON CONTRACTOR'S REMEDY 51 The remedies of Contractor hereunder shall be limited to, and Owner shall be liable only for, work actually performed by Contractor and/or its subcontractors as set forth in the contract documents, and Owner shall not be liable for any consequential, punitive or indirect loss or damage that Contractor, may suffer in connection with the project which is the subject matter of this contract. The Contractor is required to furnish a performance bond in accordance with Chapter 2253, Government Code, in the amount of 100% of the total contract price in the event that said contract price exceeds $100,000 and the Contractor is required to furnish a payment bond in accordance with Chapter 2253, Government Code, in the amount of 100% of the total contract price in the event that said contract price exceeds $25,000. All bonds shall be submitted on forms supplied by the Owner, and executed by an approved Surety Company authorized to do business in the State of Texas. It is further agreed that this contract shalt not be in effect until such bonds are so furnished. SPECIAL CONDITIONS In the event special conditions are contained herein as part of the contract documents and said special conditions conflict with any of the general conditions contained in this contract, then in such event the special conditions shall control. 52. LOSS OR EXPENSE DUE TO UNUSUAL OR UNANTICIPATED CIRCUMSTANCES Unless otherwise specified herein, all loss, expense 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 or from unusual obstructions or difficulties, naturally occurring, man made or otherwise, which may be encountered in the prosecution of the work, shall be sustained and borne by the Contractor at his own cost and expense. „". 53. INDEPENDENT CONTRACTOR Contractor is, and shall remain, an independent contractor with full, complete and exclusive power and authority to direct, supervise, and control its own employees and to determine the method of the performance of the work covered hereby. The fact that the Owner or Owner's Representative shall have the right to observe Contractor's work during Contractor's performance and to carry out the other prerogatives which are expressly reserved to and vested in the Owner or Owner's Representative hereunder, is not intended to and shall not at any time change or !^"* effect the status of the Contractor as an independent contractor with respect to either the Owner or Owner's Representative or to the Contractor's own employees or to any other person, firm, or corporation. 54. CLEANING UP The Contractor shall at all times keep the premises free from accumulation of debris caused by the work, and at the completion of the work Contractor shall remove all such debris and also its tools, scaffolding, and surplus materials and shall leave the work room clean or its equivalent.

See Section 01300, SUBMITTALS for submittal information on direct shear requirements. PART 3 - EXECUTION 3.1 PREPARATION Before placing GCL, the Contractor shall provide written documentation that the surfaces to receive GCL have been inspected and are acceptable for installation of the lining. Acceptable surface conditions shall be as described in Section 02200, EARTHWORK and in the SLQCP with no excessive cracking (defined as cracks at least 1 -inch in depth and 12 -inches in length). 3.2 ANCHOR TRENCH Anchor trenches shall be excavated as specified prior to liner system placement. 3.3 PLACEMENT A. Sheets will be placed in such a manner as to reduce field seams to a minimum. B. Proof -roll subgrade prior to GCL placement. In order to minimize subgrade degradation, GCL placement will commence within four (4) hours of proof -rolling. C. The Installer shall be responsible for the following: ■ No equipment or tools shall damage the GCL by handling, trafficking, or other means. No personnel working on the GCL shall smoke, wear damaging shoes, or engage in other activities that could damage the GCL. ■ The method used to unroll the panels shall not cause crimps or other damage to the GCL. ■ The method used to place the panels shall minimize wrinkles. Wrinkles shall be identified as to proper location and compensation shall be identified on the Contractor's 01416001 GEOSYNTHETIC CLAY LINER 02240-9 04/01 and Engineer's drawings. Ballast shall be used to prevent relocation of the compensating wrinkles by wind. ■ Adequate loading (e.g., sand bags or similar items that will not damage the GCL) shall be placed to prevent uplift by wind (in case of high winds, continuous loading is recommended along edges of panels to minimize risk of wind flow under the panels). ■ Direct contact with the GCL shall be minimized, i.e., the GCL in traffic areas is protected by geotextiles, excess geomembrane, or other suitable materials. ■ No objects which would be potentially harmful to the GCL or overlying layers remain under, within or on top of the GCL (i.e., tools, needles, stones, etc.). ■ Dragging of GCL material on subgrade will be avoided. D. Weather Limitations GCL placement shall not be done during any precipitation or times of impending precipitation, when the relative humidity exceeds 80 percent, or in the presence of excessive winds, as determined by the installation supervisor. The GCL shall not be placed in the presence of surface moisture (e.g., dew, frost) or on ponded water. GCL which becomes hydrated prior to being covered must be replaced. E. Geosynthetic Liner Protection GCL placement will be limited to that amount that can be installed and covered with geomembrane in one working day. GCL will not be left uncovered and exposed to the elements at the end of any day. F. Damaged Material Replacement GCL which has becomes hydrated before being covered shall be removed and replaced. 3.4 FIELD SEAMING A. Seam Overlap & Bentonite Fillet Seams shall be overlapped as recommended by the manufacturer. For bentonite/geotextile GCLs overlaps shall extend to the manufacturer's printed match line. A fillet of dry granular bentonite will be poured at a rate of 1/4 pound per linear foot, or as recommended by the manufacturer if the GCL has non -woven geotextile encasement, along the entire length of all overlap seams. For bentonite/geomembrane GCLs, the overlap will be a minimum of six inches. Sheets will be overlapped a minimum of 12 inches at leachate collection sumps. B. Seams on Slopes Panels shall be oriented so that the long edges are parallel to the direction of maximum slope. Lateral field seams on side slopes will be avoided if at all possible. However, if extremely long side slopes (longer than the maximum length of roll that the GCL material is available or manufactured) are included in the project, seams along the face of the side slopes will be considered under the following circumstances: ■ If seams will be required across side slopes, the Design Engineer will be contacted by the product manufacturer during the bid phase of the project. ■ In all cases, should lateral seams be required on side slopes, the manufacturers of the products, the installers of the products, the Contractor, the Geotechnical Professional and the Design Engineer will review the situation and make recommendations as to the integrity of the seaming method and the entire lining system as it relates to the lateral seams. ■ In the case of GCL consisting of bentonite supported by geotextiles, the GCL panels will be overlapped a minimum of three (3) feet with uppermost panel overlapping the lower panel. A water resistant adhesive will be applied in the overlapped areas. 01416001 GEOSYNTHETIC CLAY LINER 02240-10 04/01 ma ■ In the case of GCL consisting of bentonite supported by a geomembrane, no lateral seams across slopes will be allowed. 3.5 SIDE SLOPES On side slopes, non -woven geotextile material will be placed facing down and textured GML will be placed facing down. 3.6 REPAIRS Any necessary repairs to the GCL shall be made by placing a patch of the same material extending at least one (1) foot beyond the flaw or damaged area. Granular bentonite shall be added to the overlapped area at a uniform rate of at least 1/4 pound per linear foot. Adhesive of the type approved by the manufacturer may be used to keep patches in place during placement of overlying materials. 3.7 LEACHATE COLLECTION SUMP AND DITCH LINING Sheets shall be overlapped at least one foot at leachate collection sumps and ditches. An extra layer of GCL material will be placed at the bottom of leachate collection sumps. 3.8 GCL ACCEPTANCE The Installer shall retain all ownership and responsibility for the GCL until acceptance by the Owner. The GCL shall be accepted by the Owner when all of the following conditions are met: ■ Installation is finished. ■ Verification of the adequacy of all field seams and repairs is complete. • Written certification, including "as built" drawing(s), is provided by the Installer to the Engineer. ■ Documentation of completed installation, including all reports is complete. ■ Acceptance of "Soil and Liner Evaluation Report" by the TNRCC.

PART 3 - EXECUTION 3.1 ANCHOR TRENCH The anchor trench shall be excavated as specified prior to liner system placement. 3.2 PLACEMENT A. The Installer shall be responsible for the following: ■ No equipment or tools shall damage the geomembrane by handling, trafficking, or other means. ■ No personnel working on the geomembrane shall smoke, wear damaging shoes, or engage in other activities that could damage the geomembrane. ■ The method used to unroll the panels shall not cause scratches or crimps in the geomembrane and shall not cause indentations in the supporting soil greater than one inch deep or damage to the underlying geotextile. ■ The method used to place the panels shall minimize wrinkles. Wrinkles shall be identified as to proper location and compensation shall be identified on the Contractor's and Engineer's drawings. Ballast shall be used to prevent relocation of the compensating wrinkles by wind. 01416001 GEOMEMBRANE LINER 02245-10 04/01 r-� ■ Adequate loading (e.g., sand bags or similar items that will not damage the geomembrane) shall be placed to prevent uplift by wind (in case of high winds, continuous loading is recommended along edges of panels to minimize risk of wind flow under the panels). ■ Direct contact with the geomembrane shall be minimized, i.e., the geomembrane in traffic areas is protected by geotextiles, extra geomembrane, or other suitable materials. B. Weather Limitations Geomembrane deployment shall proceed between ambient temperatures of 32 E F to 104 ❑ F. Placement can proceed below 32[IF only after it has been verified by the Engineer that the material can be seamed according to the specification. Below 40!EIF, preheat of the GML will be required. Geomembrane placement shall not be done during any precipitation, in the presence of excessive moisture (e.g., fog, rain, dew) or in the presence of excessive winds, as determined by the installation supervisor. C. Geomembrane Protection Geomembrane will not be left exposed to weather for more than seven (7) consecutive calendar days. D. Factory Seam Quality Verifications The Engineer will require the Contractor to test up to as much as 20% of factory fusion welds (non-destructive air pressure test and/or vacuum test) in the field to verify factory test results. Additional testing at the Installer's expense will be required if failed tests are obtained in the field. 1.3 FIELD SEAMING Seams shall be oriented parallel to the line of maximum slope, i.e., oriented down, not across the slope. In comers and odd -shaped geometric locations, the number of field seams shall be minimized. No base T -seam shall be closer than 5 feet from the toe of the slope. Seams shall be aligned with the least possible number of wrinkles and "fishmouths." If a fishmouth or wrinkle is found, it shall be relieved and cap -stripped. A. Seam Overlap Panels of geomembrane must have a finished overlap of a minimum of 4 inches for hot shoe fusion welding and 3 inches for extrusion welding, but in any event sufficient overlap shall be provided to allow peel tests to be performed on the seam. No solvent or adhesive may be used unless the product is approved by the Owners Representative. (Samples shall be submitted to the Design Engineer for testing and evaluation). The procedure used to temporarily bond adjacent panels together shall not damage the geomembrane; r., in particular, the temperature of hot air at the nozzle of any spot welding apparatus shall be controlled such that the geomembrane is not damaged. B. Seaming Equipment and Accessories Approved equipment for field seaming are hot shoe fusion welders and extrusion welders. 1. Hot Shoe Welder, 110 Volt, 10 Amps. 2. Extrusion Welder, 220 Volt, 19 Amps. 3.

Field Tensiometer, capable of performing seam and peel adhesion tests for quantitative testing on-site. C. Test Seams Field test seams shall be conducted on geomembrane liner to verify that seaming conditions are satisfactory. Test seams shall be conducted for each seamer at the beginning of each seaming period, at the Engineer's discretion, and at least once each 4 hours, for each seaming apparatus used that day. All test seams shall be made at a location selected by the Engineer in the area of the seaming and in contact with the subgrade. The test seam samples shall be 10 feet long for hot shoe welding and 3 feet long for extrusion welding with the seam centered lengthwise. Specimens 1 inch wide shall be cut from each opposite end of the test seam by the Engineer. The Engineer shall use a tensiometer provided by the Installer to test these specimens for shear and peel. If a test seam fails to meet field seam specifications, the seaming apparatus and/or seamer shall not be accepted and shall not be used for seaming until the deficiencies are corrected and two consecutive successful full test seams are achieved. D. Non -Destructive Seam Testing The Installer shall non-destructively test all field seams over their full length. All test equipment, including but not limited to the following shall be furnished by the Installer: 1. Vacuum Box testing Equipment for testing single wedge fusion seams and extrusion seams shall be comprised of the following: ■ A vacuum box assembly consisting of a rigid housing, a transparent viewing window, a soft rubber gasket attached to the bottom, port hole or valve assembly, and a vacuum gauge. ■ A steel vacuum tank and pump assembly equipped with a pressure controller and pipe connections. ■ A rubber pressure/vacuum hose with fittings and connections. • A plastic bucket and wide paint brush. ■ A soapy solution. The following procedures shall be followed by the installer: ■ Excess sheet overlap shall be trimmed away. ■ Clean the window, gasket surfaces and check for leaks. ■ Energize the vacuum pump and reduce the tank pressure to approximately 3-5 psi. ■ Wet a strip of geomembrane approximately 12 inches by 48 inches (length of box) with the soapy solution. • Place the box over the wetted area and compress. ■ Close the bleed valve and open the vacuum valve. ■ Ensure that a leak tight seal is created. ■ For a period of approximately 15 seconds, examine the geomembrane through the viewing window for the presence of soap bubbles. 01416001 GEOMEMBRANE LINER 02245-12 04/01 W ■ If no bubbles appear after 15 seconds, close the vacuum valve and open the bleed valve, move the box over the next adjoining area with a minimum 3 inches overlap and repeat the process. All areas where soap bubbles appear shall be marked and repaired and then retested. The following procedures shall apply to locations where seams cannot be non-destructively tested, as determined by the Engineer: ■ If the seam is accessible to testing equipment prior to final installation, the seam shall be non-destructively tested prior to final installation. ■ If the seam cannot be tested prior to final installation, the seaming operations shall be observed by the Engineer for uniformity and completeness. 2. Air Pressure Testing (For Double Fusion Seam Only) The following procedures are applicable to those processes which produce a double seam with an enclosed space. Equipment for testing double fusion seams shall be comprised of the following: ■ An air pump equipped with pressure gauge capable of generating and sustaining a pressure between 25 and 30 psi and mounted on a cushion to protect the geomembrane. ■ A manometer equipped with a sharp hollow needle, or other approved pressure feed device. The following procedures shall be followed by the Installer: ■ Seal one end of the seam to be tested. ■ Insert needle or other approved pressure feed device through the sealed end of the channel created by the double wedge fusion weld. ■ Energize the air pump to verify the unobstructed passage of air through the channel. ■ Seal the other end of the channel. ■ Energize the air pump to a pressure between 25 and 30 psi, close valve, and sustain pressure for approximately 5 minutes. ■ If loss of pressure exceeds 4 psi, or pressure does not stabilize, locate faulty area, repair and retest. ■ Remove needle or other approved pressure feed device and seal. E. Destructive Seam Testing The Installer shall provide the Engineer with a minimum of one destructive test sample per 500 feet of seam length from a location specified by the Engineer. The Installer shall not be informed in advance of the sample location. 1. Sampling Procedure In order to obtain test results prior to completion of liner installation, samples shall be cut by the Installer as the seaming progresses. A destructive test must be done for each welding machine used for seaming or repairs. Sampling times and locations shall be determined by the Engineer. The Engineer must witness the obtainment of all field test samples and the Installer shall mark all samples with their location roll and seam number. The Installer shall also record in written form the date, time, location, roll seam number, ambient temperatures, and pass or fail description. A copy of the information must be attached to each sample portion. All holes in the geomembrane resulting from obtaining the seam samples shall be immediately repaired. All patches shall be vacuum tested. 01416001 GEOMEMBRANE LINER 02245-13 04/01 Size and Disposition of Samples The samples shall be 12 inches wide by 36 inches long with the seam centered lengthwise. The sample shall be cut into two equal length pieces, and given to the Engineer. 3. Field Testing The Installer shall cut six 1 -inch wide replicate specimens from his sample and these shall be tested by the Engineer. The Installer shall test two specimens (four when possible for testing -~ both tracks on dual -track fusion welded seams) for peel strength. All tests to be witnessed by the Engineer. To be acceptable, both test specimens must pass. Any specimen that fails through the weld or by adhesion at the weldsheet interface is a Non-FTB break and shall be considered a failure. 4. Independent Laboratory Testing The Engineer will package and ship all destructive seam samples to an independent testing Laboratory for determination and verification of all field shear and peel strengths. The test method and procedures to be used by the Independent Laboratory shall be the same used in field testing, where seam samples are 1 inch wide, and the grip separation rate is 2 ipm. The minimum passing criteria for independent laboratory testing are all three of the following: ■ All seam samples tested in the peel mode must fail in FTB. ■ At least four of five seam samples from each peel and shear determination must meet the minimum specified value. ■ The average value from all five seam samples from each peel and shear determination must meet the minimum specified value. The above criteria apply to both tracks from each dual -track fusion welded seam before it is considered as passing. ALL FAILED LAB TESTS WILL BE PAID FOR BY THE INSTALLER. 5. Archive Samples _. The Installer will package and ship the remaining samples to the Engineer for archival. The samples shall include information that indicates where the sample was taken. 6. Procedures for Destructive Test Failure The following procedures shall apply whenever a sample fails the field destructive test: ■ The installer shall cap strip the seam between the failed location and any passed test location. ■ The installer can retrace the welding path to an intermediate location (at a minimum of 10 feet from the location of the failed test), at the Engineer's discretion, and take a small sample for an additional field test. If this test passes, then the seam shall be cap stripped between that location and the original failed location. If the test fails, then the process is repeated. ■ Over the length of seam failure, the Contractor shall either cut out the old seam, reposition the panel and reseam, or add a cap strip, as required by the Engineer. ■ After reseaming or placement of the cap strip, additional destructive field test(s) shall be taken within the reseamed area. The reseamed sample shall be found acceptable if test results are approved by the Engineer. If test results are not acceptable, this process shall „ be repeated until the reseamed length is judged satisfactory by the Engineer. In the event that a sample fails a laboratory destructive test, then the above procedures shall be followed, considering laboratory tests exclusively. The Engineer will document all actions taken in conjunction with destructive test failures. 01416001 GEOMEMBRANE LINER 02245-14 04/01 F. Defects and Repairs All seams and non -seam areas of the geomembrane shall be inspected by the Engineer for defects, holes, blisters, undispersed raw materials, and any sign of contamination by foreign matter. Because light reflected by the geomembrane helps to detect defects, the surface of the geomembrane shall be clean at the time of inspection. The geomembrane surface shall be brushed, blown, or washed by the Installer if the amount of dust or mud inhibits_ inspection. The Engineer shall decide if cleaning of the geomembrane is needed to facilitate inspection. L Evaluation , Each suspect location in seam and non -seam areas shall be non-destructively tested as appropriate in the presence of the Engineer. Each location that fails the non-destructive testing shall be marked by the Engineer, and repaired accordingly. 2. Repair Procedures ■ Defective seams shall be restarted/reseamed as described in these specifications. ■ Small holes shall be repaired by extrusion cap welding. If the hole is larger than 3 inch, ,.., it shall be patched. ■ Tears shall be repaired by patching. Where the tear is on a slope or an area of stress and has a sharp end it must be rounded prior to patching. ■ Blisters, large holes, undispersed raw materials, and contamination by foreign matter shall be repaired by patches. ■ Surfaces of HDPE which are to be patched shall be abraded and cleaned no more than 15 minutes prior to the repair. No more than 10% of the thickness shall be removed. Patches shall be round or oval in shape, made of the same geomembrane, and extend a minimum of 6 inches beyond the edge of defects. All patches shall be of the same compound and thickness as the geomembrane specified. All patches shall have their top edge beveled with an angle grinder prior to placement on the geomembrane. Patches shall be applied using approved methods only. 3. Restart/Reseaming Procedures The welding process shall restart by grinding the existing seam and rewelding a new seam. Welding shall commence where the grinding started and must overlap the previous seam by at least 2 inches. Reseaming over an existing seam without regrinding shall not be permitted. 4. Verification of Repairs Each repair shall be non-destructively tested, except when the Engineer requires a destructive seam sample obtained from a repaired seam. Repairs that pass the non-destructive test shall be taken as an indication of an adequate repair. Failed tests indicate that the repair shall be repeated and retested until passing test results are achieved. Recording of Results: daily documentation of all non-destructive and destructive testing shall be provided to the Engineer by the Installer. This documentation shall identify all seams that initially failed the test and include evidence that these seams were repaired and successfully retested. 01416001 GEOMEMBRANE LINER 04/01 02245-15 1.4 GEOMEMBRANE ACCEPTANCE The Installer shall retain all ownership and responsibility for the geomembrane until acceptance by the Owner. The surface of the geomembrane shall not have striations, roughness, pinholes, or bubbles and shall be free of holes, blisters, undispersed raw materials, or any contamination by foreign matter; except that if in the opinion of the Engineer the blemish will not adversely affect properties and use of the geomembrane, the Engineer may accept the geomembrane after sufficient laboratory test data are provided to support such acceptance, and further, provided all such testing is done at the sole expense of the Installer. The geomembrane liner shall be accepted by the Owner when all of the following conditions are met: ■ Installation is finished. ■ Verification of the adequacy of all field seams and repairs, including associated testing, is complete. ■ Written certification, including "as built" drawing(s), is provided by the Installer to the Engineer. ■ Documentation of completed installation, including all reports is complete. ■ Acceptance of "Flexible Membrane Liner Evaluation Report" by the TNRCC.
