Newmont-Cripple Creek&Victor Gold Mine <br /> Technical Specification No.01400-2.DOCX ■ <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> June 15,2016 <br /> 6.3.1. Geomembrane <br /> During geomembrane installation, the CQA Monitor shall observe and document deployment, <br /> trial seams, field seaming, non-destructive and destructive seam testing, and repairs to assure <br /> that the installation is in 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 <br /> as 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 the <br /> deployment log form. <br /> Trial Seams - The CQA Monitor shall verify that seaming conditions are performed in <br /> compliance with SPECIFICATIONS, tests are performed at required intervals, specified test <br /> procedures are followed, and retests are performed in compliance with the SPECIFICATIONS. If <br /> the ambient air temperature measured by the CQA Monitor is above 357 for the entire day, <br /> the INSTALLER shall perform trial seams at the beginning of each crew shift, and immediately <br /> following any work stoppage (i.e., for lunch, weather conditions, etc.) of for more than 30 <br /> minutes or at the discretion of the CERTIFYING ENGINEER, for each seaming apparatus used <br /> that day. If the ambient air temperature measured by the CQA Monitor is below 35°F for the <br /> entire day, the INSTALLER shall perform four (4) trial seams, at approximately the same time <br /> interval throughout the scheduled work day. Each Seamer shall make at least one trial seam <br /> each day. Seaming operation shall not commence until the CQA Monitor has determined that <br /> the seaming process is meeting the SPECIFICATION requirement and is acceptable. The CQA <br /> Monitor shall record the trial 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 <br /> project SPECIFICATIONS, specified overlaps are achieved, seams are oriented in compliance to <br /> project requirements, and that grinding techniques and extrudate meet project requirements <br /> for extrusion welding. The CQA Monitor shall record all field seaming on field seaming log <br /> 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 <br /> operations. The CQA Monitor shall verify that test equipment and gauges are functioning <br /> properly and that test procedures are in compliance with the project SPECIFICATIONS. The <br /> CQA Monitor shall verify that all seams and repairs with failing test results are repaired and/or <br /> Page 8 <br />
