Footing trench excavation continued within the northern limits (Int. ftng. J/3) 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 either previously placed processed gravel structural fill or urban fill containing wood, ash, brick, slag etc. The excavation generally fell on the transition. A 6 - 12" thick layer of ¾" crushed stone was placed and graded. The surface of the stone was compacted utilizing the heavy plate compactor exhibiting stable/firm conditions. Installation of drainage utilities was performed through building 1. The 12" diameter class 4 RCP was installed from previously installed DMH 4 east toward proposed DMH 14. The penetration in the wall was used although a new hole will need to be cored at the penetration adjacent to DMH 14. The piping was bedded and covered in ¾" crushed stone. The shallow trench was then backfilled using the same structural fill generated during excavation. The area was compacted utilizing the IR drum roller exhibiting stable/firm conditions. Rough and fine grading was performed for proposed pavement areas. Base course material was previously placed. The material used is 1.5" reprocessed material from the Caruso pit in Revere, MA. Minor cuts and fills were made utilizing the Deere bulldozer and grader.
