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 Owner's Representative, or if the Contractor fails to comply with the orders of the Owner's Representative, when such orders are consistent with this contract, this Agreement, or the Specifications hereto attached, 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. After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment, r 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. In case the Surety should fail to commence compliance with the notice for completion herembefore provided for within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (a) The Owner may 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 his 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 P 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. However, should the cost to n 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. 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 42 heremabove 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, 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 thirty (30) days after the date of 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 tamed 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 t site of the work, notice thereof, together with an itemized list of such equipment and materials shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract; provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale ! may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any l machinery, equipment, tools, materials, or supplies which remain on the *jobsite and belong to persons other than the Contractor or his Surety, to their proper owners. 50. AANDOI ME BY OWNERBY OWNER In case the Owner shall fail to comply with the terms of this contract, and should fail or refuse to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, tools, and equipment, and all materials on the ground that have not been included in payments to the Contractor and have not been incorporated into the work Thereupon, the Owner's Representative 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 bid, 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 Owner's Representative 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. 51. 13ONDS The successful bidder shall be required to furnish a performance bond and payment bond in accordance with Article 5160, Vemon's Annotated Civil Statutes in the amount of 100% of the total contract price, in the event said contract price exceeds $25,000.00.

Destructive Seam Testing The installer shall provide the Engineer with a minimum of one destructive test sample per 500 feet of scam length from a location specified by the Engineer. The Installer shaU 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 art by the installer as the seaming progresses. A destructive test must be dome 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 scam number. The Installer shall also record in written form the date, tare, 2797-95 02245 -14 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 i geomembranc resulting from obtaining the seam samples shall be immediately repaired. All patches shall be vacuum tested. 2. Size and Disposition of Samples The samples shall be 12 inches wide by 36 inches long with the scam centered lengthwise. The sample shall be cut into two equal length pieces, and given to the r' Engineer. 3.

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 fr(m all five scam 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 S. Archive Samples The Installer will package and ship the remaining smmmples 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 fags the field destructive test • The installer shall cap strip the seam between the failed iflcation and any passed test location • The installer can retrace the welding path to an is mmediate location (at a minimum of 10 feet fium 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 fans, then the pa=m is repeated a i 2787-95 02245.15 r • Over the length of seam failure, the Contractor shall either cut out the old seam, reposition the panel and rmmm, or add a cap strip, as required by the Engineer- g or placement of the cap strip, additional destructive field tests) shall be taken within the reseamed area. The reseamed sample shall be found acceptable if test results ace 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. F. Defects and Repairs All seams and non -scam 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 Engmw shall decide if cleaning of the geomembmae is needed to facilitate inspection. 1.
