ameO Non-Destructive Seam Continuity Testing - The CQA Monitor shall verify that all seams and repair are non-destructively tested in compliance with the project SPECIFICATIONS. If a seam cannot be tested, the seam shall be capped. The CQA Monitor shall observe capping operations. The CQA Monitor shall verify that test equipment and gauges are functioning properly and that test procedures are in compliance with the project SPECIFICATIONS. The CQA Monitor shall verify that all seams and repairs with failing test results are repaired and/or re-tested until passing results are achieved. The CQA Monitor shall record all non-destructive test locations on the vacuum test and pressure test log forms. Destructive Seam Testing - The INSTALLER shall obtain samples, at locations selected by the CQA Monitor, of the field seamed geomembrane approximately 24 inches along and 12 inches across the seam and centered over the seam as follows: ■ a minimum of one sample per day; ■ a minimum of one sample for each geomembrane seamer; ■ a minimum of one sample every 500 feet of seaming;and ■ seams that appear suspect to the CQA Monitor. The CQA Monitor shall witness the testing of destructive seam samples by the INSTALLER. The INSTALLER shall mark all samples with their roll and seam number,date,machine number, welding technician identification, extruder and nozzle/wedge temperature, and ambient air temperature. The INSTALLER shall test all destructive samples in compliance with the project SPECIFICATIONS. The INSTALLER shall be responsible for patching all areas cut for test samples in accordance with the SPECIFICATIONS and MANUFACTURER's requirements and performing non- destructive testing (i.e., vacuum box) of the seams. The CQA Monitor shall record test locations on the geomembrane defect log forms. Additional testing information will be recorded on the geomembrane seam destructive sample log form. The CQA Monitor shall track failing tests as described in the SPECIFICATIONS. Repairs- The CQA Monitor shall observe and document that all repair materials,techniques, and procedures used for repairs are approved in advance and meet the requirements of the project SPECIFICATIONS. The CQA Monitor shall verify that all defects and repairs are marked, recorded, repaired, tested, and wrinkles are addressed, prior to being covered by other materials; and that repairs are performed as specified, including proper patch size or dimension. The CQA Monitor shall record defects and repairs on the defect and repair log forms. 6.03.02 GEOTEXTILE: During geotextile installation, the CQA Monitor shall observe and document deployment, field seaming, and repairs to assure that the installation is in compliance with the SPECIFICATIONS. Deployment - The CQA Monitor shall verify that the subgrade is free of deleterious materials prior to deployment, anchoring is achieved as specified, specified methods are used to minimize wrinkles and protect underlying layers during cutting of materials,and deployment procedures are performed in compliance with the project SPECIFICATIONS.
