stockpile to the Phase 5 Berm Raise. Moisture conditioning of SLF material was performed in <br />place using a tandem -axle water truck and compaction was achieved using a 10 -ton vibratory <br />smooth drum compactor. Nuclear density testing, moisture verification, and depth check testing <br />was performed with results within project specifications. Test locations were surveyed by Ames. <br />F) Drain Cover Fill (DCF) <br />No work performed during the week. <br />II) Geosynthetics <br />A) Geomembrane Installation <br />Geomembrane installation within the Phase 5 Berm Raise footprint continued performing <br />deployment, seaming, and repair /QC activities. Approximately 18,797 square feet of 80miI LLDPE <br />was deployed using a Doosan 225 excavator with spreader -bar attachments. Subgrade was <br />inspected and approved by AMEC and Lonestar representatives prior to geomembrane <br />deployment. Approximately 736 linear feet of seam was fusion welded using one fusion welding <br />machine /welding technician combination. Three destructive test samples were marked during <br />fusion seaming. Approximately 779 linear feet of seam was extrusion welded using one extrusion <br />welding machine /welding technician combination. Three destructive test samples were marked <br />during extrusion seaming. All destructive tests performed were within project specifications. Non- <br />destructive testing was performed for fusion welded seams. Repairs were performed using the <br />extrusion welding method for all marked defects. Vacuum testing was performed for all extrusion <br />welded seams and repairs. <br />B) Geomembrane Exposure <br />No work performed during the week. <br />C) Anchor Trench <br />Anchor trench was excavated using a CAT 304 mini excavator and one laborer. The anchor <br />trench was inspected by an AMEC field representative and found to be constructed in accordance <br />with design drawings and project specifications. <br />Anchor trench backfill was performed using a CAT 304 excavator, a CAT 312 excavator with <br />vibratory plate attachment and laborers. An AMEC field representative observed the backfill and it <br />was found to be constructed in accordance with design drawings and project specifications. <br />D) Geomembrane Acceptance <br />No work performed during the week. <br />CQA ACTIVITIES: <br />ame0 <br />SUMMARY: <br />The CQA activities performed consisted of observing, documenting and recording the construction <br />activities of the contractor. <br />AMEC observed subgrade preparation for the Phase 5 Berm Raise. <br />AMEC inspected and approved subgrade for SLF placement for the Phase 5 Berm Raise. <br />AMEC observed, assisted, and performed testing during placement of SLF for the Phase 5 Berm Raise. <br />P5BR.Weekly Report WE 09.01.2012 <br />
