amee* <br />VLF Geosynthetics <br />B) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued performing deployment, <br />seaming, and repair/QC activities. Geomembrane installation was performed in the area shown <br />on Figure 3. Approximately 41,325 square feet of primary 80mil LLDPE was deployed using a <br />John Deere 200 excavator and a John Deere 544 front-end loader with spreader-bar <br />attachments. Subgrade was inspected and approved by AMEC and Lone Star representatives <br />prior to geomembrane deployment (see Figure 3). Approximately 2,368 linear feet of seam was <br />fusion welded using to two fusion welding machines. Five destructive test samples were <br />marked during fusion seaming. All destructive tests performed were within project <br />specifications. Non-destructive testing was performed for fusion welded seams. Repairs were <br />performed using the extrusion welding method for all marked defects. Vacuum testing was <br />performed for all extrusion welded seams and repairs. <br />C) Anchor Trench <br />1) VLF <br />Anchor trench excavation was performed between stations A48+00 (+/-) and A54+00 (+/-) <br />using a CAT 35 D excavator and laborers. An AMEC representative observed and inspected <br />the anchor trench excavation. The trench was found to be constructed in accordance with <br />design drawings and project specifications. <br />Anchor trench backfill was performed between stations E 17+00 (+/-) and E20+50 (+/-) using a <br />John Deere 35D excavator, a jumping jack compactor, and laborers. An AMEC representative <br />observed and inspected the anchor trench backfill. The trench was found to be backfilled in <br />accordance with design drawings and project specifications. <br />D) Geomembrane Acceptance <br />1) VLF <br />No geomembrane was accepted during the week (see Figure 4 for previous geomembrane <br />acceptance). <br />E) Geomembrane Delivery <br />1) VLF <br />No geomembrane was delivered to site 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 inspected and approved subgrade prior to SLF placement. <br />AMEC observed SLF placement. <br />VLF Weekly Report WE 10.30.10.13
