OBSERVATIONS:
Perimeter footing trench excavation continued within the Southern limits of proposed building #2
along column line 2 (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 in consistency from organic silt with ash, wood and clay
to tannin bark. A layer of mirafi 160 filter fabric was placed atop the sub grade as specified. 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.
Installation of water utilities was performed at the south side and in between buildings 1&2. The
trench was carried down to design elevation utilizing the Deere 380 excavator. The class 52 CLDI piping
was installed and bedded in clean imported bedding sand. Mechanical joint fittings and boulder thrust
blocks were used at all bends. The trench was backfilled using the same material generated during
excavation generally consisting of F - C gravel and sand, trace silt placing. 12 - 18" thick lifts were
placed and graded. Each lift was compacted employing several passes of coverage utilizing the heavy
Wacker plate compactor exhibiting stable/firm conditions.
