ame <br />Earth & Environmental <br />IV)VLF Geosynthetics <br />A) Geomembrane Installation <br />1) VLF <br />Geomembrane installation within the Phase 5 VLF continued throughout the week, performing <br />deployment, seaming, and repair/QC activities. Geomembrane installation was performed in <br />the area shown on Figures 3a and 3b. Approximately 258,668 square feet of 100mil LLDPE <br />geomembrane was deployed using a John Deere 200 excavator and a John Deere 544 front-end <br />loader with spreader-bar attachments. Subgrade was inspected and approved by AMEC and <br />Lonestar representatives prior to geomembrane deployment (see Figures 3a and 3b). <br />Approximately 13,605 linear feet of seam was fusion welded during deployment using up to <br />three fusion welding machine. Thirty-three destructive test samples were marked during fusion <br />seaming. Approximately 181 linear feet of seam was extrusion welded during using one <br />extrusion welding machine. One destructive test sample was marked during extrusion seaming. <br />All destructive sample test results met project specifications. Non-destructive testing was <br />performed for all 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) Geomembrane Acceptance <br />1) VLF <br />80 mil primary (P-1 thru P-63), 100mil primary (P-1 thru P-179), and 100mil secondary (5-464 <br />thru S-560) geomembrane shown on Figures 4a, 4b, and 4c was inspected by AMEC and <br />Lonestar representatives and found to be installed within project specifications and acceptable <br />for continued construction activities. <br />C) Geomembrane Delivery <br />1) VLF <br />One load consisting of four 80mil LLDPE single sided textured rolls and eight 100mi1 LLDPE <br />smooth geomembrane rolls was delivered to site during the week. The load was delivered on a <br />flat bed truck in good condition. The rolls were unloaded using a CAT 966 front-end loader <br />with forks attached. The geomembrane was placed on three pieces of HDPE pipe, stacked two <br />rolls high. An AMEC field representative inventoried the geomembrane and was present at all <br />times during unloading of the geomembrane. <br />D) Anchor Trench <br />1) VLF <br />No work performed 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 within the Phase 5 VLF. <br />VLF Weekly Report WE 07.31.1O.D
