4 CONSTRUCTION QUALITY ASSURANCE FOR GEOSYNTHETICS 4.1 General The objectives of the geosynthetics CQA program are to: (i) assure that proper construction techniques and procedures are used; and (ii) that the project is completed in accordance with the Construction Drawings and Specifications. The intent of the CQA program is to: (i) to identify and define problems that may occur during construction; and (ii) to verify that these problems are corrected before construction is complete. This section describes CQA procedures for the installation of geosynthetic components. The following types of geosynthetics will be utilized for this project: • Non -woven filter and cushion geotextile; • 60 -mil HDPE single and double sided textured geomembrane; • Geocomposite Drainage Net (geotextile on one side); and • Geosynthetic Clay Liner • Geogrid CQA for the geosynthetics installations will be performed to verify that geosynthetics are installed in accordance with the design. Construction must be conducted in accordance with the Construction Drawings and Specifications. To monitor compliance, the CQA program will (i) review the Contractor's quality control submittals; (ii) perform material acceptance testing; (iii) monitor and perform seam testing; and (iv) monitor installations. Control testing will be performed by the material manufacturer. The manufacturer will submit a quality control program prior to construction for the QA/QC Consultant to review and approve. The manufacturer's testing shall comply with the standards and frequencies as contained in the Specifications. Acceptance criteria are defined in the Specifications. All CQA testing will be conducted in accordance with this CQA manual, and the Specifications. If a discrepancy exists in the testing requirements, the document that requires the most stringent testing will govern. Page 26 0
