<br /> Page 40 <br />ft., whichever is more stringent, to ensure conformance to both the Specifications and the <br />Manufacturers list of guaranteed properties. The material will be sampled at the site by the QA/QC <br />Inspectors or at the manufacturing plant by an independent third party under the direction of the <br />QA/QC Consultant. <br /> <br />As a minimum, the following will be established: <br /> <br />• Bentonite mass per unit area per ASTM D5993; <br />• Peel strength of GCLs per ASTM D6496; and <br />• Hydraulic conductivity of GCLs per ASTM D5887. <br /> <br />Direct Shear Testing (ASTM D6243/D5321). The QA/QC Consultant shall perform a direct shear <br />test (minimum one test per project or material type) between the project specific GCL, textured <br />geomembrane, and geocomposite drainage net per ASTM D6243/D5321 and as described in the <br />Specifications. <br /> <br />The QA/QC Manager will review all acceptance test results and report any non-conformance to the <br />Construction Manager and Contractor. <br /> <br />Sampling Procedures. Samples will be taken across the entire width of the roll. Unless otherwise <br />specified, samples will be 3 ft (1 m) long by the roll width. The QA/QC Consultant will mark the <br />machine direction on the samples with an arrow. <br /> <br />Test Results. The QA/QC Consultant will examine all results from laboratory acceptance testing <br />and will report any nonconformance to the Construction Manager. <br /> <br />Acceptance Test Failure. If a GCL acceptance sample does not comply with the minimum <br />requirements of the Specifications, the GCL roll from which the sample was taken will be failed by <br />the QA/QC Consultant, and replaced by the GCL Manufacturer at no additional cost to the Owner. <br />The Design Engineer shall be contacted to determine additional acceptance testing requirements. <br /> <br />4.5.3 GCL Installation <br /> <br />The Geosynthetics Contractor will handle all GCLs in such a manner as to ensure that they are not <br />damaged in any way, and will comply with the following. <br /> <br />• In the presence of wind, all GCLs will be sufficiently weighted with sandbags to prevent <br />their movement. Such sandbags will be installed during placement and will remain until <br />replaced with the overlying layer.
