Geomembrane installation was performed in the area shown <br />on Figures 3a, 3b and 3c. Approximately 265,406 square feet of primary 80mi1 LLDPE and <br />primary 100mil LLDPE was deployed using a John Deere 200 excavator and a John Deere 544 <br />front-end loader with spreader-bar attachments. Subgrade was inspected and approved by <br />AMEC and Lone Star representatives prior to geomembrane deployment (see Figures 3a, 3b <br />and 3c). Approximately 13,891 linear feet of seam was fusion welded using to two fusion <br />welding machines. Twenty-nine destructive test samples were marked during fusion seaming. <br />All destructive tests performed were within project specifications. Non-destructive testing was <br />performed for fusion welded seams. Repairs were performed using the extrusion welding <br />method for all marked defects. Vacuum testing was performed for all extrusion welded seams <br />and repairs. <br />B) Anchor Trench <br />1) VLF <br />Anchor trench backfill was performed between stations G15+00 (+/-) and G23+00 (+/-) and <br />between stations E21+00 (+/-) and E23+50 (+/-) using a John Deere 35D excavator and <br />laborers. An AMEC representative observed and inspected the anchor trench backfill. The <br />trench was found to be backfilled in accordance with design drawings and project <br />specifications. <br />Anchor trench excavation was performed between stations K4+00 (+/-) and A64+20 (+/-) <br />using a CAT 312 excavator and laborers. An AMEC representative observed and inspected the <br />anchor trench excavation. The trench was found to be constructed in accordance with design <br />drawings and project specifications. <br />C) Geomembrane Acceptance <br />1) VLF <br />Primary 80mi1 geomembrane (P-86 thru P-113) shown on Figure 4a and primary 100mil <br />geomembrane (P-402 thru P-415, P-496 thru P-522, P-524 and P-525) shown on Figures 4b <br />and 4c, were inspected by AMEC and Lonestar representatives and found to be installed within <br />project specifications and acceptable for continued construction activities. <br />VLF Weekly Report WE 10.02.10.1)
