Footing excavation continued within the Southeastern limits of building 1. The trench was excavated to design elevation utilizing the Deere 450 excavator equipped with a flat cutting edge (flared teeth) to minimize sub grade disturbance. Ground improvements were previously completed in this area by installing GCC deep foundation elements. The elements were previously excavated to design cutoff elevation. The area was over excavated a minimum 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 existing loamy urban fill generally consisting of F - M sand, little gravel, little silt containing wood, organic silt, ash, slag etc. A 6 - 12" thick layer of ¾" crushed stone was placed and graded. Mirafi filter fabric was placed between the sub grade and crushed stone footing base material. The surface of the stone was compacted utilizing the heavy plate compactor exhibiting stable/firm conditions. Placement of slab base course materials was initiated within the Western limits of building 1. The material used is imported 1 ½" reprocessed material from the Lorusso Pit in Revere, MA. A single 15" thick lift was placed and graded utilizing the Deere bulldozer. An access ramp was constructed at the permanent ramp location for building access using the same material described above. The material was compacted employing several passes of coverage utilizing the wacker ½ ton plate compactor and IR 10 ton drum roller exhibiting stable/firm conditions. Some of the existing in place material was allowed to remain as base course material on a case by case basis depending on consistency.
