0 • Observation of the preparation of the subgrade surface. <br />• Verification that cover soils are derived from appropriate sources. <br />Visual evaluation of soil material properties for consistency with the Project <br />Drawings and Specifications. <br />• Identification of deleterious materials or other deficiencies in soil quality to minimize <br />the possibility that these materials are incorporated into the final cover system. <br />• Monitoring of moisture conditioning, mixing, blending, and processing for uniformity <br />of material and moisture content. <br />• Monitoring of activities for removal and/or disaggregation of oversize material from <br />the fill. <br />• Evaluation of the constructed cover material for conformance with the Project <br />Drawings and Specifications. <br />• Observation of uniformity of coverage of compaction equipment, especially at fill <br />edges, turnaround areas and on slope faces. <br />• Monitoring of lift thickness. <br />• Observation of the active fill pad at the beginning of each grading day and <br />establishment of requirements for wetting/drying and/or processing of the exposed <br />surface prior to placement of additional fill. <br />• Undertaking field tests including but not limited to field moisture/density content and <br />hydraulic conductivity testing at the minimum frequencies noted herein or at any time <br />that a deficiency is suspected. <br />• Recovery of samples for laboratory testing. <br />• Laboratory testing of the moisture content and density, grain size distribution and <br />hydraulic conductivity of fill materials in accordance with the requirements of the <br />Specifications (including retests if necessary). <br />• Confirmation that the test results are in accordance with the Project Specifications <br />(including retests of any previously failed area). <br />1 UUL Nfie';; <br />In order to facilitate construction, close coordination between the Project Director/Project <br />Manager, Construction Manager, Engineer, Geotechnical CQA Consultant, Contractor (including <br />-7- <br />Gr.AnOOS-OOSVFORWARD/CQAPLAN.dod7/i 512005 <br />GeoLogic Associates <br />
