F <br />1. Acceptance of construction below <br />waterproofing and perimeter insulation. <br />2. Inspection, testing, approval, and <br />underground utilities. <br />3. Removal of shoring and bracing, and <br />satisfactory materials. <br />finish grade including <br />recording locations of <br />backfilling of voids with <br />C. Remove vegetation, debris, unsatisfactory soil materials, obstructions, <br />and deleterious materials from ground surface prior to placement of <br />fills. Plow strip, or break -up sloped surfaces steeper than 1 vertical to <br />4 horizontal so that fill material will bond with existing surface. <br />D. When existing ground surface has a density less than that specified for <br />1 particular area classification, break up ground surface, pulverize, <br />moisture - condition to optimum moisture content, and compact to <br />required depth and percentage of maximum density. <br />1 E. Place backfill and fill materials in layers of 8 in. loose depth for <br />material compacted by heavy compaction equipment, and 4 in. in <br />loose depth for material compacted by hand operated tampers. <br />F. Before compaction, moisten or aerate each layer as necessary to <br />provide optimum moisture content. Do not place backfill or fill <br />material on surfaces that are muddy, frozen, or contain frost or ice. <br />it <br />1 <br />G. Place backfill and fill materials evenly adjacent to structures, without <br />wedging against structures or displacement of piping or conduit. <br />Compaction equipment used within 10 ft. of buried walls and soil <br />supported structures shall not exceed 2000 lbs. <br />3.04 GRADING <br />A. Grading Outside Building Lines: Grade areas adjacent to building lines <br />to drain away from structures and to prevent ponding and as follows: <br />1 . Finish to within not more than 0.10 ft. above or below required <br />subgrade elevations. <br />2. Walks: Shape surface to line, grade and cross - section, with <br />finish surface not more than 0.10 ft. above or below required <br />subgrade elevation. <br />3. Pavements: Shape surface to line, grade and cross - section, <br />with finish surface 1/2 in. above or below required subgrade <br />elevation. <br />07/03 02200 -5 03- 4138.A <br />
