amecwO <br />C) Anchor Trench <br />1) VLF <br />Excavation of the existing anchor trench was performed between stations E0+00 (+/-) and <br />E9+00 (+/-) and between stations K1+50 (+/-) and K6+00 (+/-) was performed to allow for soil <br />liner fill (SLF) placement in the area. This was performed using a John Deere 35D and <br />laborers. An AMEC field representative observed the anchor trench excavation constantly. The <br />full depth of the anchor trench was excavated were saturated SLF was encountered. <br />Anchor trench backfill was performed between stations E0+00 (+/-) and E9+00 (+/-) and <br />between stations K1+50 (+/-) and K6+00 (+/-) using a John Deere excavator, a vibratory plate <br />compactor, and laborers. This was performed to replace any saturated SLF removed from the <br />trench An AMEC field representative observed the backfill and it was found to be performed <br />in accordance with design drawings and project specifications. <br />D) Geomembrane Acceptance <br />1) VLF <br />No geomembrane was deployed or accepted during the week. <br />E) Geomembrane Delivery <br />1) VLF <br />One load (11 rolls) of 80mil LLDPE single sided textured geomembrane rolls were delivered <br />to site during the week. The load was delivered on a flat bed truck in good condition. The rolls <br />were unloaded using a forklift. The geomembrane was placed on three pieces of HDPE pipe, <br />stacked two rolls high. An AMEC field representative inventoried the geomembrane and was <br />present at all times during unloading of the geomembrane. <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 structural fill placement within the Phase 5 VLF fill area. Ambient and fill temperatures <br />were monitored during fill placement. <br />AMEC observed slope contouring within the Phase 5 VLF. <br />AMEC observed compaction of subgrade. <br />AMEC observed the construction of the leak detection trench. <br />AMEC observed the exposure of previously installed geomembrane. <br />AMEC observed the excavation and backfill of the existing (temporary) Phase 5 anchor trench. <br />VLF Weekly Report WE 05.28.2011
