Geomembrane installation was performed in the area shown <br />on Figure 3. Approximately 229,047 square feet of primary 80mi1 LLDPE was deployed using <br />a 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 12,095 linear feet of seam <br />was fusion welded using four fusion welding machines. Twenty-seven destructive test samples <br />were 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 H23+00 (+/-) and H28+00 (+/-) and <br />between stations A60+00 (+/-) and A64+00 (+/-) using a CAT 312 excavator and laborers. An <br />AMEC representative observed and inspected the anchor trench excavation. The trench was <br />found to be constructed in accordance with design drawings and project specifications. <br />Anchor trench backfill was performed between stations H31+00 (+/-) and H33+00 (+/-) and <br />between stations A54+00 (+/-) and A62+00 (+/-) using a CAT 312 excavator, a jumping jack <br />compactor, and laborers. An AMEC representative observed and inspected the anchor trench <br />backfill. The trench was found to be backfilled in accordance with design drawings and project <br />specifications. <br />VLF Weekly Report WE 11.06.10.
