The intent of the CQA program is to: (i) to identify and <br />define problems that may occur during construction; and (ii) to verify that these problems are <br />corrected before construction is complete. <br /> <br />This section describes CQA procedures for the installation of geosynthetic components. The <br />following types of geosynthetics will be utilized for this project: <br /> <br /> Geotextile; <br /> <br /> 60-mil HDPE single-sided textured geomembrane; <br /> <br /> Geosynthetic Clay Liner <br /> <br />CQA for the geosynthetics installations will be performed to verify that geosynthetics are installed in <br />accordance with the design. Construction must be conducted in accordance with the Construction <br />Drawings and Specifications. To monitor compliance, the CQA program will (i) review the <br />Contractor's quality control submittals; (ii) perform material acceptance testing; (iii) monitor and <br />perform seam testing; and (iv) monitor installations. <br /> <br />Control testing will be performed by the material manufacturer. The manufacturer will submit a <br />quality control program prior to construction for the QA/QC Consultant to review and approve. The <br />manufacturer’s testing shall comply with the standards and frequencies as contained in the <br />Specifications. Acceptance criteria are defined in the Specifications. <br /> <br />All CQA testing will be conducted in accordance with this CQA manual and the Specifications. If a <br />discrepancy exists in the testing requirements, the document that requires the most stringent testing <br />will govern. <br />
