Earthworks Construction Quality Assurance <br /> All earthwork activities for the Squaw Gulch VLF Phase 2A Part 1 project were performed in <br /> accordance with the design drawings and project specifications as discussed in Section 2. The <br /> CQA Monitor observed, documented, and performed testing during material placement. This <br /> included; ensuring the proper materials were placed, fills were free of deleterious materials, lift <br /> placement was performed uniformly and on a firm and unyielding underlying layer, haulage <br /> traffic was spread across fill surfaces when practical, moisture conditioning was performed <br /> uniformly with acceptable moisture content, the proper method specification was used when <br /> applicable, and specified densities were achieved during field testing. Earthworks laboratory <br /> and field testing and frequencies are summarized in Table 2. <br /> The CQA Monitor checked ambient temperatures and logged the daily high and low <br /> temperatures, maximum wind speeds and amount of precipitation in Table 3. If earthwork <br /> activities were performed while the ambient temperature was below 32°F, fill temperatures <br /> were monitored by the CQA Monitor to ensure no frozen material was placed. Ambient and fill <br /> temperatures are presented in Table 4. <br /> P:\Projects\0106.032 VLF2 Phase 2 CQA\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 10 <br />
