amec` <br />Earth 8 Envtronmantal <br />Granular Fill material (CEntry specification) was hauled to the new ADR tank manhole excavation <br />using a 40-ton articulating haul truck loaded by a CAT 966 front-end loader. The material was <br />placed in two 8" lifts and compacted using a jumping jack compactor. Four nuclear density tests <br />were performed by an AMEC representative with results averaging 95% of maximum dry density. <br />H) Miscellaneous <br />No work performed during the week. <br />III) Underground Working <br />A) Drilling <br />No work performed during the week. <br />B) Mine Shaft/Stope Remediation <br />No work performed during the week. <br />C) Lateral/Slot Remediation <br />No work performed during the week. <br />IV) Storm Water Management Structures <br />A) Control Structures <br />No work performed during the week. <br />B) Best Management Practices <br />Best Management Practices are being observed throughout the VLF Phase 5 Project. <br />V) VLF Geosynthetics <br />No work performed during the week. <br />CQA ACTIVITIES: <br />SUMMARY: <br />The CQA activities performed consisted of observing, documenting and recording the construction <br />activities of the contractor. <br />AMEC observed placement of structural fill within the Phase 5 VLF fill area. <br />AMEC observed and accepted subgrade preparation within the Phase 5 fill area. <br />AMEC observed the construction of the new ADR water tank. Subgrade was accepted for granular fill <br />placement. Granular fill placement was also observed and tested by an AMEC representative. <br />Testing Summary <br />Laboratory testing continues (Particle Size Distribution, Atterberg Limits, and Moisture-Density <br />Compaction testing) for sampled materials. <br />Sheet 4 of 8 <br />VLF Weekly Report WE 08.01.09.D.doc
