The weekly construction progress reports are presented in <br />Appendix E. The timeline of activities documented in the reports is listed below: <br /> Week ending May 16, 2025, to Week ending July 26, 2025 – SLF placement <br /> Week ending June 6, 2025, to July 11, 2025 – Structural Fill placement <br /> Week ending June 13, 2025, to July 26, 2025 – Geomembrane deployment <br /> Week ending July 11, 2025, to September 5, 2025 – DCF placement <br /> <br />Photographs of key construction elements captured by the CQA monitor throughout the project <br />are presented in Appendix F. All testing and inspections were performed in accordance with the <br />Technical Specifications presented in Appendix C. <br />3.1. Testing Standards <br />The CQA Monitor completed the earthwork laboratory testing at the on-site soils laboratory to <br />verify that all earthwork construction materials met the project Technical Specifications. <br />Geomembrane samples were sent to a third-party laboratory to verify that the material <br />properties met the project Technical Specifications. Testing was performed in accordance with <br />these American Society for Testing and Materials (ASTM) standards. <br />3.1.1. Earthworks Testing Standards <br /> Particle size analysis (ASTM C117, C136, D1140, D6913) <br /> Atterberg limits (ASTM D4318) <br /> Laboratory moisture/density relationship (ASTM D698) <br /> Moisture Content (ASTM D2216) <br /> Flexible Wall Permeability (ASTM D5084, Method D) <br /> Density of soil in place by nuclear method (ASTM D6938) <br /> Soil Classification (ASTM D2488) <br />3.1.2. Geomembrane Testing Standards <br /> Thickness (ASTM D5199/D5994) <br /> Density (ASTM D1505/D792, Method B) <br /> Carbon Black Content (ASTM D4218) <br /> Carbon Black Dispersion (ASTM D5596) <br /> Tensile Properties (ASTM D6693) <br /> Ultimate Elongation (ASTM D6693)
