In areas to receive turf, rough grade to allow for sod thickness in all areas to be <br />sodded, verify that soil contains enough organic matter to support and encourage <br />rooting of sod. Fill is to be fine, compacted satisfactory fill material with no rocks <br />larger than 2-inches. <br /> <br />B. Both surface and subsurface before and after fill operations shall be checked to <br />confirm that percolation/compaction levels meet the needs of the proposed <br />planting for that area. <br /> <br />Part 3 - Execution <br /> <br />3.01 Excavation <br /> <br />A. Excavate or fill where necessary to obtain subgrades, percolation and surface <br />drainage as required. <br /> <br />B. Materials to be excavated are unclassified. <br /> <br />C. Remove entirely any existing obstructions after approval by the Landscape <br />Architect's or Owner's Representative. <br /> <br />D. Remove from site and dispose of debris and excavated material not required. <br /> <br />3.02 Grading <br /> <br />A.

Under landscape area, compaction shall not exceed 85% of maximum <br />density. <br /> <br />B. No backfill shall be placed against any masonry or other exposed building <br />surface until permission has been given by the Owner's Representative, and in <br />no case until the masonry has been in place seven days. <br /> <br />C. Compaction in limited areas shall be obtained by the use of mechanical tampers <br />or approved hand tampers. When hand tampers are used, the materials shall be <br />deposited in layers not more than four inches thick. The hand tampers used <br /> <br />06/07 <br /> <br />02210-2 <br /> <br />03-4197 <br />
