Cripple Creek&Victor Gold Mining Company _ <br /> Squaw Gulch VLF Phase 2A Part 1 ■ <br /> Record of Construction Report <br /> 475.0106.032 <br /> July 22,2019 <br /> Welding machines were continually inspected for proper operation, settings and condition by <br /> performing trial welds prior to actual geomembrane installation. Logs of the trial welds, panels, <br /> seams, continuity testing, repairs, and destructive testing were maintained by both the <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 <br /> with design drawings and project specifications. Record Drawing No. 5 shows panel locations, <br /> 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 <br /> NewFields representative and met the Technical Specifications. Third party conformance <br /> test results are presented for 40mil and 80mil geomembranes in Appendix L.1 and L.2, <br /> 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 <br /> that 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 <br /> results 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 <br /> day. 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 <br /> used 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 <br /> deployed. The Geomembrane Panel Deployment Summary is presented in Appendix K.1. <br /> P:\Projects\0106.032 VLF2 Phase 2 CCA\J-REPORTS\ROC Report 1\Cert Report-Phase 2A Part 1\475.0106.032 CCV PHASE 2A Part 1 <br /> ROC REPORT docx <br /> Page 15 <br />
