OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Footing excavation continued within the limits of building 1 (interior footings Cl J@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 existing fill generally consisting of
F - C gravel and sand, trace silt. 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.
Foundation backfilling continued within the SW limits of building 1 for rooms # 001 - 003. This
work was performed in preparation of masonry CMU installation in the area. The material used is the
soil generated during interior footing excavation within building 1 and generally consists of F - M
sand and gravel, trace silt. The material is a blend of onsite and imported gravel. 12 - 18" thick
lifts were placed and graded utilizing the Deere 380 excavator. Each lift was compacted employing
several passes of coverage utilizing the Wacker plate compactor exhibiting stable/firm conditions. The
walls were backfilled simultaneously on both sides to prevent lateral stresses on the foundation
