Construction of the valley leach facility or specified geosynthetics must be in <br />compliance with the design plans and SPECIFICATIONS. CC&V shall implement a CQA <br />monitoring and testing program to ensure construction compliance by the <br />CONTRACTOR. The quality assurance program shall consist of reviewing <br />CONTRACTOR quality control submittals, material conformance testing, construction <br />monitoring and testing. <br />The types of geosynthetics used in the valley leach facility construction include <br />polyethylene pipe, geomembrane and geotextile. These geosynthetics are defined in the <br />project SPECIFICATIONS. Prior to and during construction, these geosynthetics shall be <br />sampled and tested to determine if they meet project SPECIFICATIONS. All tests shall <br />be performed in a geosynthetics laboratory approved by the MANAGER. <br />6.01 REVIEW QUALITY CONTROL SUBMITTALS: <br />Prior to geosynthetic installation, the CQA Monitor shall review the INSTALLER'S quality <br />control submittals to evaluate or confirm that these materials meet project requirements. <br />The CQA Monitor shall review the QC submittals that are outlined in Section 2776 <br />(Geomembrane) and Section 02777 (Geotextile) of the SPECIFICATIONS. <br />6.02 GEOMEMBRANE CONFORMANCE TESTING: <br />Prior to geosynthetic installation, the CQA Monitor shall obtain samples of the <br />geomembrane for conformance testing to confirm that these materials meet project <br />requirements. The conformance testing frequency shall be at a rate of 1 test per <br />150,000 square feet. Samples shall be taken across the entire width of the roll and shall <br />not include the first 3 feet. The samples shall be 3 feet wide by the roll width. The <br />CQA Monitor shall mark the machine direction, roll number on the sample, and date the <br />sample was obtained and forward the sample to a third party geosynthetic laboratory. <br />As a minimum, the following conformance tests shall be conducted; with project <br />requirements outlined in Section 02776, Article 2.01: <br />? Geomembrane: density (ASTM D1505) <br />carbon black content (ASTM D1603) <br />thickness (GRI-GM8) <br />tensile strength (ASTM D638) <br />All conformance tests shall be performed in compliance with the project <br />SPECIFICATIONS. The CQA Monitor shall review the test results and shall report any <br />nonconformance to the MANAGER, CERTIFYING ENGINEER and the Geosynthetics <br />Installation CONTRACTOR. <br />6.03 CONSTRUCTION MONITORING AND TESTING: <br />The CQA Monitor shall monitor and test all geosynthetic components of the <br />construction to verify that the construction is in compliance with the project <br />SPECIFICATIONS. The CQA Monitor shall identify inadequate construction <br />methodologies or materials which may adversely impact the performance of the facility <br />being constructed and existing structures. Visual observations throughout the <br />construction process shall be made to ensure that the materials are placed to the lines <br />and grades as shown on the DRAWINGS. <br />Section 01400.2 Page 6 of 12 March 22, 2000 <br />Geosynthetic CQA Plan Golder Associates Revision 5 <br />1AM209911inal reportlapecs1014002Mdoc
