• 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 /> 4.0 MEETINGS <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 /> GLA/2005-0082/FOR WARD/CQAPLAN.doc/7/15/2005 <br /> Geologic Associates <br />
