OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Foundation backfilling continued at the western perimeter of building 2 along column line G from
11 - 17 (see sketch). The material used is 2" minus imported processed gravel consisting of F - C
gravel, some sand, trace silt. Approximately 12 - 16" thick lifts were placed and graded utilizing the
Deere 75G excavator. An access ramp was constructed from column line 12 - 13 @ G. Each lift was
compacted employing several passes of coverage utilizing the Wacker ½ ton plate compactor or IR 10 ton
drum roller exhibiting stable/firm conditions.
Perimeter footing trench excavation continued within the limits of proposed building #2 along
column lines G and 8 (see sketch). 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 recently completed in this area by installing GCC deep foundation elements. The area
was over excavated 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 significantly in consistency from organic silt with wood
and clay to gravel to tannin bark. A layer of mirafi 160 filter fabric was placed atop the sub grade as
specified. Compaction of the sub grade will not be feasible due to the soft organic sub grade soils. A
6" thick layer of ¾" crushed stone was placed and graded. The surface of the stone was compacted
utilizing the heavy plate compactor generally exhibiting stable/firm conditions.
