Geomembrane installation was performed in the area shown <br />on Figure 3. Approximately 39,202 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 2,227 linear feet of seam was <br />fusion welded using four fusion welding machines. Six destructive test samples were marked <br />during fusion seaming. Approximately 423 linear feet of seam was extrusion welded using one <br />extrusion welding machine. Two destructive test samples were 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 excavation was performed between stations K7+00 (+/-) and K7+50 (+/-)using <br />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 />Anchor trench backfill was performed between stations A48+00 (+/-) and A54+00 (+/-) and <br />between stations H23+00 (+/-) and H31+00 (+/-) and between stations K1+50 (+/-) and K4+00 <br />+/-) using a CAT 312 excavator, a jumping jack compactor/vibratory plate compactor, 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 />VLF Weekly Report WE 11.
