LEIGHTON CONSULTING, INC. <br />General Earthwork and Grading Specifications <br />1.0 General <br />1.1 Intent <br />These General Earthwork and Grading Specifications are for the grading and <br />earthwork shown on the approved grading plan(s) and/or indicated in the <br />geotechnical report(s). These Specifications are a part of the recommendations <br />contained in the geotechnical report(s).In case of conflict, the specific <br />recommendations in the geotechnical report shall supersede these more general <br />Specifications. Observations of the earthwork by the project Geotechnical <br />Consultant during the course of grading may result in new or revised <br />recommendations that could supersede these specifications or the <br />recommendations in the geotechnical report(s). <br />1.2 The Geotechnical Consultant of Record <br />Prior to commencement of work, the owner shall employ the Geotechnical <br />Consultant of Record (Geotechnical Consultant). The Geotechnical Consultants <br />shall be responsible for reviewing the approved geotechnical report(s) and <br />accepting the adequacy of the preliminary geotechnical findings, conclusions, and <br />recommendations prior to the commencement of the grading. <br />Prior to commencement of grading, the Geotechnical Consultant shall review the <br />"work plan" prepared by the Earthwork Contractor (Contractor) and schedule <br />sufficient personnel to perform the appropriate level of observation, mapping, and <br />compaction testing. <br />During the grading and earthwork operations, the Geotechnical Consultant shall <br />observe, map, and document the subsurface exposures to verify the geotechnical <br />design assumptions. If the observed conditions are found to be significantly <br />different than the interpreted assumptions during the design phase, the <br />Geotechnical Consultant shall inform the owner, recommend appropriate changes <br />in design to accommodate the observed conditions, and notify the review agency <br />where required. Subsurface areas to be geotechnically observed, mapped, <br />elevations recorded, and/or tested include natural ground after it has been cleared <br />for receiving fill but before fill is placed, bottoms of all "remedial removal" areas, <br />all key bottoms, and benches made on sloping ground to receive fill. <br />The Geotechnical Consultant shall observe the moisture-conditioning and <br />processing of the subgrade and fill materials and perform relative compaction <br />testing of fill to determine the attained level of compaction. The Geotechnical <br />Consultant shall provide the test results to the owner and the Contractor on a <br />routine and frequent basis. <br />F-1 <br />SL Rvcd 2019.01.21
