• observe that required overlap distances are met; <br />• monitor and record ambient air temperatures; <br />• verify that no continuous horizontal seams are placed on slopes unless approved by <br />CERTIFYING ENGINEER; and <br />• observe and document that all soil materials placed on top of the geosynthetics are done in <br />such a manner as to ensure that the geosynthetics are not damaged. <br />6.03.01 GEOMEMBRANE: <br />ame0 <br />During geomembrane installation, the CQA Monitor shall observe and document deployment, trial seams, <br />field seaming, non - destructive and destructive seam testing, and repairs to assure that the installation is in <br />compliance with the SPECIFICATIONS. <br />Deployment - The CQA Monitor shall verify that only approved materials are used, each panel is <br />given a unique panel number, no geomembrane is placed during unsuitable weather conditions as <br />outlined in Section 02776, Article 1.05 of the SPECIFICATIONS, the geomembrane is not <br />damaged during installation, and anchoring is performed in compliance with the <br />SPECIFICATIONS and design DRAWINGS. The CQA Monitor shall record the deployment on <br />the deployment log form. <br />Trial Seams - The CQA Monitor shall verify that seaming conditions are performed in compliance <br />with SPECIFICATIONS, tests are performed at required intervals, specified test procedures are <br />followed, and retests are performed in compliance with the SPECIFICATIONS. If the ambient air <br />temperature measured by the CQA Monitor is above 35 °F for the entire day, the INSTALLER <br />shall perform trial seams at the beginning of each crew shift, and immediately following any work <br />stoppage (i.e., for lunch, weather conditions, etc.) of for more than 1 hour or at the discretion of <br />the CERTIFYING ENGINEER, for each seaming apparatus used that day. If the ambient air <br />temperature measured by the CQA Monitor is below 35 °F for the entire day, the INSTALLER <br />shall perform four (4) trial seams, at approximately the same time interval throughout the <br />scheduled work day. Each Seamer shall make at least one trial seam each day. Seaming operation <br />shall not commence until the CQA Monitor has determined that the seaming process is meeting <br />the SPECIFICATION requirement and is acceptable. The CQA Monitor shall record the trial <br />weld results on the trial seam log form. <br />Field Seaming - The CQA Monitor shall verify that only approved equipment and personnel <br />perform welding, all welding is performed under suitable conditions as specified in the project <br />SPECIFICATIONS, specified overlaps are achieved, seams are oriented in compliance to project <br />requirements, and that grinding techniques and extrudate meet project requirements for extrusion <br />welding. The CQA Monitor shall record all field seaming on field seaming log forms. <br />Non - Destructive Seam Continuity Testing - The CQA Monitor shall verify that all seams and <br />repair are non - destructively tested in compliance with the project SPECIFICATIONS. If a seam <br />cannot be tested, the seam shall be capped. The CQA Monitor shall observe capping operations. <br />The CQA Monitor shall verify that test equipment and gauges are functioning properly and that <br />test procedures are in compliance with the project SPECIFICATIONS. The CQA Monitor shall <br />verify that all seams and repairs with failing test results are repaired and/or re- tested until passing <br />results are achieved. The CQA Monitor shall record all non - destructive test locations on the <br />vacuum test and pressure test log forms. <br />Section 01400.2 Page 7 of 11 June 19, 2012 <br />Geosynthetic CQA Plan Revision 1 <br />
