amec-, <br />B) Anchor Trench <br />Approximately 560 feet of anchor trench was excavated using a CAT 304 and John Deere 120 <br />excavator and laborers. The anchor trench was inspected by an AMEC field representative and <br />found to be constructed in accordance with design drawings and project specifications. <br />Approximately 675 feet of anchor trench backfill was performed using a CAT 312 excavator, a <br />vibratory plate compactor and laborers. An AMEC field representative observed the backfill and it <br />was found to be constructed in accordance with design drawings and project specifications. <br />C) Geomembrane Exposure <br />No work performed during the week. <br />D) Geomembrane Acceptance <br />Primary 80mil geomembrane shown on Figure 5 (P270 -P339 and P381 -P410) was inspected by <br />AMEC and Lonestar representatives and found to be installed within project specifications and <br />acceptable for continued construction activities. <br />III) Storm Water Management <br />A) Best Management Practices (BMP) <br />Best Management Practices are being observed throughout the Mill Site Earthworks project. <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 and assisted with SLF placement within the Mill Site Earthworks project, including <br />ambient and fill temperature monitoring when necessary. <br />AMEC inspected and approved subgrade prior to geomembrane deployment. <br />AMEC observed, logged data, and assisted in the installation of geomembrane within the Mill Site <br />Earthworks project. <br />AMEC inspected and approved 80mil primary geomembrane within the Mill Site Earthworks project. <br />AMEC observed anchor trench excavation and backfill for the Mill Site Earthworks project. <br />AMEC observed DCF placement within the Mill Site Earthworks project, including ambient and fill <br />temperature monitoring when necessary. <br />AMEC observed overburden fill placement for the Mill Site Earthworks project, including ambient and fill <br />temperature monitoring when necessary. <br />Testing Summary <br />Laboratory testing continued (Particle Size Distribution, Atterberg Limits, Moisture - Density Relations, <br />Specific Gravity, Permeability, and Point Load testing) for sampled materials. <br />MEW Weekly Report WE 11.03.2012 <br />
