shipment, handling, and placement shall be rejected. Liner <br />• panels shall remain in the shipping containers or shall be <br />covered and protected from the elements until ready for <br />installation. Only liner panels for each day's seaming shall <br />be spread. <br />The liner panels shall be oriented in such a manner as <br />to minimize stress on the factory and field seams. To this end, <br />liner panels shall be placed with factory seams and long field <br />seams oriented longitudinally with the slopes (positioned up <br />and down slopes). <br />The liner panels shall be temporarily anchored and held <br />in place with sandbags, piles of earth, or other approved <br />methods until completion of field seaming and placement of <br />tailings. Permanent anchoring at the edge of the liner shall <br />be as shown on the Drawings. Care should be taken to ensure <br />that the liner panels are positioned in a slackened condition <br />• ~ so that they will conform to the subgrade without being taut <br />when covered with drainage blanket and tailings material. The <br />liner panels shall be placed and smoothed so that the direct <br />contact with the prepared subsoils is maximized. Cutting of <br />the liner to remove excess material shall be performed. The <br />liner panels shall be positioned in such a way as to prevent <br />excessive wrinkles at the overlaps where field seaming will <br />be completed. <br />7.3.3 eamin <br />Sheets shall be of the maximum width produced by the <br />manufacturer. Before the adoption of a particular seaming <br />technique, the Contractor shall supply the Engineer with <br />written details of the method and equipment to be used. <br />Operating criteria and specifications for the seaming technique <br />and equipment shall be submitted. Approval of the seaming <br />• technique shall be obtained from the Engineer pricer to its use. <br />34 <br />
