Ground improvements were recently completed in this area by installing GCC deep foundation elements. The area was over excavated a minimum of 6" below design BOF elevation to provide a cushion/base of material between the elements and the footing. All GCC elements were carefully located and exposed during excavation. The sub grade soil in this area is fill and varies in consistency from recently placed processed gravel to urban loamy fill with organic silt, ash, gravel, slag, wood Etc. The sub grade was generally dry and firm. A 6" - 12" thick layer of ¾" or 2" processed gravel was placed at each location. The gravel was moisture conditioned and compacted employing several passes of coverage utilizing the heavy plate compactor generally exhibiting stable/firm conditions. Installation of drainage utilities was performed at the south side and in between buildings 1&2. The trench was carried down to design elevation utilizing the Deere 380 excavator. DMH 4, 5 and 6 were installed. The sub grade was previously prepared using crushed stone and gravel to accommodate the structures. The structures were connected using the respective HDPE piping (18 or 24" diameter). The piping was bedded ¾ up the pipe in ¾" crushed stone. The remaining bedding/backfill material used is the same material generated during excavation generally consisting of F - C gravel and sand, trace silt placing. 12 - 18" thick lifts were placed and graded. Each lift was compacted employing several passes of coverage utilizing the heavy Wacker plate compactor exhibiting stable/firm conditions.
