IV) VLF Geosynthetics
A) Geomembrane Installation
1) VLF
Geomembrane installation within the Phase 5 VLF continued performing deployment,
seaming, and repair /QC activities. Geomembrane installation was performed in the area shown
on Figures 3a, 3b and 3c. Approximately 265,406 square feet of primary 80mil LLDPE and
primary 100mil LLDPE was deployed using a John Deere 200 excavator and a John Deere 544
front -end loader with spreader -bar attachments. Subgrade was inspected and approved by
AMEC and Lone Star representatives prior to geomembrane deployment (see Figures 3a, 3b
and 3c). Approximately 13,891 linear feet of seam was fusion welded using to two fusion
welding machines. Twenty -nine destructive test samples were marked during fusion seaming.
All destructive tests performed were within project specifications. Non - destructive testing was
performed for fusion welded seams. Repairs were performed using the extrusion welding
method for all marked defects. Vacuum testing was performed for all extrusion welded seams
and repairs.
B) Anchor Trench
1) VLF
Anchor trench backfill was performed between stations G15 +00 ( + / -) and G23 +00 ( + / -) and
between stations E21 +00 ( + / -) and E23 +50 ( + / -) using a John Deere 35D excavator and
laborers. An AMEC representative observed and inspected the anchor trench backfill. The
trench was found to be backfilled in accordance with design drawings and project
specifications.
Anchor trench excavation was performed between stations K4 +00 ( + / -) and A64 +20 ( + / -)
using a CAT 312 excavator and laborers. An AMEC representative observed and inspected the
anchor trench excavation. The trench was found to be constructed in accordance with design
drawings and project specifications.
C) Geomembrane Acceptance
1) VLF
Primary 80mil geomembrane (P -86 thru P -113) shown on Figure 4a and primary 100mil
geomembrane (P -402 thru P -415, P -496 thru P -522, P -524 and P -525) shown on Figures 4b
and 4c, were inspected by AMEC and Lonestar representatives and found to be installed within
project specifications and acceptable for continued construction activities.
