Phase Nc Summary No. 14 Page 3 043-2170 <br />Golder observed geomembrane deployment, documenting ambient temperature, panel dimensions, <br />thickness, seaming tie-in overlap, and seam testing (trial seams, pressure testing). Geomembrane <br />installed in the Phase IVc OSA met the project specifications. <br />Golder visually observed the placement of DCF in the Phase IVc OSA area. Golder CQA monitors <br />(one monitor per dozer when dozers aze greater than 50 feet apart) observed DCF placement and <br />verified minimum thickness of 2 feet for finish grade, and 4 feet for haul traffic (i.e., Caterpillar <br />Model 740 articulated trucks). <br />Golder observed placement of HVSC piping in the Phase IVc OSA, verifying installation and layout <br />per the project plans. <br />Laboratory Tests <br />Golder obtained two QA samples of soil liner fill (SLFc-QA-16 and SLFc-QA-17) for laboratory <br />index testing. The completed test samples met the requirements of the specifications and the results <br />are presented in Attachment B. <br />Golder obtained two QC samples of bentonite-amended soil liner fill (SLF-QC-18a and SLF-QC-19) <br />during this reporting period. Laboratory index testing was conducted on the sample of bentonite- <br />amended SLF at the Golder field trailer to verify suitability of materials prior to use in the field. A <br />summary of QC laboratory test results for SLF materials are available at the Golder field trailer. <br />Meetings <br />CC&V held a Weekly Contractors' meeting on August 10, 2004.
