pff1/ /lr's ' <br />summarized in Table 1. CQC earthworks testing was provided to support the contractor during <br />the manufacture of materials Bedding Fill (BF) and prior to material placement. <br />AMEC provided CQA laboratory and field testing, and monitored earthworks construction <br />activities as follows: <br />AMEC monitored site excavation and grading, including slope re- contouring and fill <br />placement, lift thickness, moisture conditioning, temperatures, and compactive effort. <br />AMEC visually monitored subgrade preparation to confirm that the subgrade surface <br />was unyielding, free of organic matter and other unsuitable materials, and that the <br />subgrade surface was compacted prior to BF placement. <br />AMEC visually monitored the placement and compaction of BF, particle size, moisture <br />conditioning, and compaction of the fill. AMEC performed in -place density and moisture <br />content testing, and performed CQA laboratory testing of grain size, moisture content, <br />Atterberg limits, and compaction. AMEC also provided visual monitoring of the BF <br />surface preparation and moisture conditioning for geosynthetic clay liner (GCL) <br />deployment, including verification that the surface was proof - rolled, compacted, and <br />hand - worked so as to be free of abrupt grade changes, and sharp stones or objects. <br />AMEC also observed the excavation, backfill, and compaction of the anchor trenches. <br />AMEC visually monitored the placement of BF above the installed geomembrane, <br />including verification of lift thickness and grade control, identification and removal of <br />deleterious materials, and verification that care was exercised in fill placement to avoid <br />geomembrane damage. AMEC performed CQA laboratory testing of grain size and <br />Atterberg limits. <br />AMEC monitored the ambient air temperatures and the temperatures of all fills, including <br />BF, in accordance with project specifications. <br />1.2.2 CQA/CQC Monitoring of Geosynthetics Installation <br />AMEC provided CQA monitoring of geosynthetics used for the LOB Liner Extension. CQC <br />services provided by AMEC consisted of performing geosynthetics inventory and checking <br />quality control certifications prior to geosynthetics deployment. AMEC performed geosynthetics <br />CQA activities in accordance with the CQA Plan. Geosynthetics CQA activities performed by <br />AMEC included: <br />2 <br />
