City of Everett 31 00 00 - 5 <br /> Inductive Charging Infrastructure for Everett Transit <br /> 2. Backfill against footings, foundations and structural walls, except 18 inches of gravel <br /> backfill for walls shall be placed immediately adjacent to structures for drainage, unless <br /> otherwise shown on the drawings. <br /> 3. Fill beneath building slabs. <br /> 4. Fill within 3 feet vertically of the base of pavements <br /> C. Fill beneath areas to be landscaped shall be nonstructural fill. <br /> D. Backfill excavations as promptly as work permits, but not until completion of the following: <br /> 1. Acceptance by Owner's Representative of construction below finish grade including, <br /> where applicable, waterproofing, dampproofing, piping, conduits and perimeter <br /> insulation. <br /> 2. Inspection, testing, approval and recording locations of underground piping and <br /> conduits. Coordinate locations with surveyor for as-built survey. <br /> 3. Removal of concrete formwork. <br /> 4. Removal of shoring and bracing and backfilling of voids with satisfactory materials. <br /> 5. Removal of trash and debris. <br /> 6. Permanent or temporary horizontal bracing is in place on horizontally supported walls. <br /> E. Ground Surface Preparation <br /> 1. Remove vegetation, debris, unsatisfactory soil materials, obstructions and deleterious <br /> materials from ground surface prior to placement of fills. On existing sloped surfaces, <br /> steeper than 1 vertical to 4 horizontal, cut benches into hillsides of 10 feet minimum <br /> width and 5 feet maximum height. <br /> 2. When existing ground surface has a density less than that specified under <br /> "Compaction" for the particular area classification, break up the ground surface, <br /> pulverize, moisture-condition to within 2 percent of the optimum moisture content, and <br /> compact to required depth and percentage of maximum density. <br /> F. Placement and Compaction: Allowable thickness of fill lifts will depend on the material <br /> type and compaction equipment used. In no case place backfill and fill materials in layers <br /> more than 8 inches in loose depth for material compacted by heavy compaction <br /> equipment, and more than 4 inches in loose depth for material compacted by hand- <br /> operated tampers. For fill deeper than 3 feet below the base of pavements, lifts may be <br /> 12 inches maximum in loose depth. <br /> 1. Before compaction, moisten or aerate each layer as necessary to provide the optimum <br /> moisture content. <br /> 2. Compact each layer to required percentage of maximum dry density or relative dry <br /> density for each area classification. <br /> 31 00 00 - 5 EARTHWORK <br />
