Cripple Creek&Victor Gold Mining Company . <br /> Squaw Gulch VLF Phase 2A Part 1 ■ <br /> Record of Construction Report <br /> 475.0106.032 <br /> August 21,2019 <br /> contractor and the CQA Monitor on a daily basis. The CQA Monitor's geomembrane installation <br /> logs are presented in Appendix J. <br /> All geomembrane installation for the Squaw Gulch VLF project was performed in accordance with <br /> design drawings and project specifications. Record Drawing (Post 2019) No. 9 shows panel <br /> locations, seams, and destructive test locations. <br /> 3.5.1. Geomembrane Third Party Conformance Testing <br /> Third party conformance test samples for geomembrane were obtained at a rate of one <br /> test for every 150,000 square feet, and at least one test for each resin lot. Samples were <br /> tested by TRI in Anaheim, CA. All conformance test results were reviewed by a NewFields <br /> representative and met the Technical Specifications.Third party conformance test results <br /> are presented for 40mil and 80mil geomembranes in Appendix L.1 and L.2, respectively. <br /> 3.5.2. Geogrid Third Party Conformance Testing <br /> Third party conformance testing on every geogrid resin lot was performed by TRI in <br /> Austin,TX. All conformance test results were reviewed by the CQA Monitor, and lots that <br /> met the project Technical Specifications were approved for use. Three lots (313074, <br /> 314354, and 314747) were rejected due to not meeting project Technical Specifications <br /> and all material from those lots was shipped off site.Third party conformance test results <br /> are presented in Appendix L.3. <br /> 3.5.3. Geomembrane Panel Deployment <br /> The SLF surface was inspected by the CQA monitor prior to geomembrane deployment, <br /> ensuring the surface was free of any protruding rock greater that 0.75" or irregularities <br /> (rutting, ridges, indentations, etc.) greater than 0.5". The SLF surface was approved by <br /> Tetra Tech,Tezak, CC&V, and the CQA Monitor prior to and during deployment each day. <br /> SLF acceptance forms are presented in Appendix F. During geomembrane panel <br /> deployment the CQA Monitor logged the dimensions of each panel, the roll number used <br /> for each panel, and measured the thickness of the panel edges. Roll numbers were <br /> checked against the site inventory to ensure only approved geomembrane was deployed. <br /> The Geomembrane Panel Deployment Summary is presented in Appendix K.1. <br /> 3.5.4. Geomembrane Fusion Seaming <br /> Double-wedge fusion welding was the primary method of geomembrane seaming for the <br /> Squaw Gulch VLF Phase 2A Part 1 project. Prior to fusion welding activities, trial welds <br /> were performed for each welding machine and welding technician combination for each <br /> type of geomembrane. The fusion welding trial seam logs are presented in Appendix <br /> P:\Projects\0106.032 VLF2 Phase 2 COA\J-REPORTS\Cert Report-Phase 2A Part 1\DRMS Comments\475.0106.032 CCV PHASE 2A Part 1 <br /> ROC REPORT_Revl.docx <br /> Page 15 <br />
