Geomembrane installation was performed in the area shown <br />on Figures 3a, 3b, and 3c. Approximately 139,201 square feet of primary 80mil LLDPE, <br />primary 100mil LLDPE and secondary 100mil LLDPE was deployed using a John Deere 200 <br />excavator and a John Deere 544 front -end loader with spreader -bar attachments. Subgrade was <br />inspected and approved by AMEC and Lone Star representatives prior to geomembrane <br />deployment (see Figure 3a, 3b, and 3c). Approximately 7,375 linear feet of seam was fusion <br />welded using three fusion welding machines. Seventeen destructive test samples were marked <br />during fusion seaming. Approximately 674 linear feet of seam was extrusion welded using two <br />extrusion welding machines. Four destructive test sample was marked during extrusion <br />seaming. All destructive tests performed were within project specifications. Non - destructive <br />testing was performed for fusion welded seams. Repairs were performed using the extrusion <br />welding method for all marked defects. Vacuum testing was performed for all extrusion <br />welded seams and repairs. <br />B) Anchor Trench <br />1) VLF <br />Anchor trench backfill was performed between stations B12+00 ( + / -) and B14+00 ( + / -) using a <br />John Deere 35D excavator and laborers. An AMEC representative observed and inspected the <br />anchor trench backfill. The trench was found to be backfilled in accordance with design <br />drawings and project specifications. <br />VLF Weekly Report WE 09.11.10.D <br />
