construction monitoring, compaction observation and testing during grading operations, and geosynthetic material observation, monitoring and documentation. Duties of the Field Engineer/Field Geologist typically include the following: • Subgrade inspection, review, testing and documentation. • Review of the adequacy of all clearing, grubbing, stripping and preparation of areas to receive fill. • Monitoring and evaluation of any soil blending, mixing and processing operations. • Evaluation of the engineering characteristics of the processed and constructed earth materials. • Observation and evaluation of all excavations which may be impacted by geologic conditions. 3.3.2 GEOTECHNICAL CQA FIELD TECHNICIANS Geotechnical CQA Technicians will be representatives of the Geotechnical'CQA Consultant and will monitor and observe grading operations and geosynthetic installation to provide a basis for concluding that construction has been carried out in conformance with the Project Drawings and Specifications. Duties typically include, but are not necessarily limited to: • Observation of subgrade surface preparation. Verification that cover soils are derived from appropriate sources. • Visual evaluation of the soils physical properties for consistency with the Project Drawings and Specifications. Evaluation of all moisture conditioning and processing operations to evaluate uniformity of material and moisture content. • Evaluation of the constructed engineered fill material for conformance with the Project Drawings and Specifications. • Identification of deleterious m�aWrtials or other deficiencies in soil characteristics to minimize the possibility that these materials are incorporated into the cover system. • Monitoring of activities for the removal and/or disaggregation of all oversize material. • Observation of uniformity of coverage of compaction equipment, especially at fill edges, turnaround areas and on slope faces. Monitoring of lift thickness. • Observation of the active fill pad at the beginning of each grading day and establishment of requirements for wetting/drying and/or processing of exposed surfaces prior to placement of additional fill. • Undertaking field tests including but not limited to field moisture/density testing at the minimum frequencies noted herein or at any time that a deficiency is suspected. • Recovery of samples for laboratory testing. -7- C:\2001-048TINAL COVER CQA.DOC\08/20/01 Geologic Associates
