P:\Projects\0106.071 2025 Resident\J-REPORTS\VLF2 P3 Stage B.1 RoC Page 13  Puncture Strength (ASTM D4833)  Peel and Shear Strength (ASTM D6392) 3.2. Earthworks Construction Quality Assurance All earthwork activities for the VLF2 Phase 3 Stage B.1 project were performed in accordance with the design drawings and project specifications as discussed in Section 1.3. The CQA Monitor observed, documented, and performed testing during material placement. This included: ensuring the proper materials were placed, fills were free of deleterious materials, lift placement was performed uniformly and on a firm and unyielding underlying layer, haulage traffic was spread across fill surfaces when practical, moisture conditioning was performed uniformly within acceptable moisture content, the proper method specification was used when applicable, and specified densities were achieved during field testing. Earthworks laboratory and field testing and frequencies are summarized in Tables 4-8. The CQA Monitor checked ambient temperatures and logged the daily high and low temperatures, maximum wind speeds and amount of precipitation in Table 3. No earthwork activities affected by ambient freezing temperatures, as per project specifications, occurred during the B.1 construction period. 3.2.1. Structural Fill VLF2 Phase 3 Stage B.1 was constructed by placing 2,450 cy of SF. The particle size distribution and Atterberg limits testing frequencies were one sample for every 50,000 cy. One SF sample was tested for particle size and Atterberg limits based on the quantity of material placed and passing results were achieved. SF laboratory testing is summarized in Table 4 and individual test results are presented in Appendix G.1. No laboratory compaction testing was performed on the SF placed within the VLF2 Phase 3 Stage B.1 area, as all SF material contained more than 30 percent retained on the ¾- inch sieve. Density was achieved by placing the material with a method exceeding past method compaction specifications. A relatively small amount of structural fill was required for Stage B.1 construction. The same contractor and compaction equipment that was utilized for Stage B.1 was also utilized for the method specification memorandum provided in VLF2 Phase 3 Stage A.1 Record of Construction report. 3.2.2. Soil Liner Fill The VLF2 Phase 3 Stage B.1 area was constructed by placing 43,944 cy of SLF. The particle size distribution, Atterberg limits, laboratory compaction, and permeability testing frequencies were one sample for every 4,000 cy. A minimum of 11 SLF samples were required and 14 SLF samples were tested and found to be within specifications. SLF laboratory testing is summarized in Table 5, and individual test results are presented in Appendix G.2.
