• Evaluation and documentation of laboratory and field testing of the in-place moisture content and density of engineered fill materials in accordance with the requirements of the Specifications (including retests, if necessary). • Confirmation that the test results are in accordance with the Project Specifications (including retests of any previously failed areas). The operations to be monitored for geosynthetics typically include, but are not necessarily limited to: • Material delivery. • Unloading and on-site transport and storage. • Placement/deployment operations. • Joining and/or seaming operations. • Repair operations. Specifically, the seaming operations to be monitored include: • Trial seams. • Seam preparation. • Seaming. • Nondestructive seam testing. • Sampling for destructive seam testing. • Laboratory test sample marking. • Repair operations. • Reviewing the final certification of seams. In addition to these specific duties, the Geoteclinical`CQA Technicians sliall'be responsible for: • Observing the condition of geosynthetic materials as placed. r„t Selecting samples wfar conformance testing -by the Independent TBstin-g Laboratory. • Marking samples for conformance testing. • Notation of any on-site activities that could result in damage to the geosynthetics. All observations shall be reported in a timely manner to the Construction Manager. 3.4 INDEPENDENT TESTING LABORATORY The Independent Testing Laboratory shall perform all conformance testing of geosynthetics and all destructive laboratory testing of field seams. The Independent Testing Laboratory shall be experienced in the performance of all conformance tests required by the CQA Plan and certified by the Geosynthetic Accreditation Institute (GAI) for each test required for the project.
