Footing excavation continued within the limits of building 1 (interior footings Cl I@3&4). 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 urban fill containing wood, ash, brick, 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. Fine grading was performed for proposed pavement areas. Specifically, efforts focused on heavy duty pavement (roadway) areas to increase the pavement cross section thickness. Base course material was previously placed. The material used is 1.5" reprocessed material from the Caruso pit in Revere, MA. Approximately 1" of material was cut utilizing the Deere grader. The surface was compacted utilizing the IR 10 ton drum roller exhibiting stable/firm conditions. The cover for CB 12 was replaced on this date. The structure was damaged shortly after installation and was removed and replaced on this date.
