OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Footing excavation was performed for elevator and stair footings located within the Southern
limits of proposed building #2 (see sketch). The trench was excavated to design elevation utilizing the
Deere 450 and 80 excavators equipped with a flat cutting edge to minimize sub grade disturbance. Ground
improvements were recently completed in this area by installing GCC deep foundation elements. The area
was over excavated approximately 12" 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 organic tannin bark. Groundwater was well controlled and
de watering was performed as necessary. A 12" thick layer of 3/4" crushed stone was placed and graded
over the sub grade. A layer of filter fabric was placed between the crushed stone and sub grade
material. The crushed stone base was compacted employing several passes of coverage utilizing the heavy
plate compactor exhibiting stable/firm conditions.
Installation of sewer utilities continued at the Flint street entrance adjacent to existing sewer
manhole #1 connection. The trench was carried down to design elevation utilizing the Deere 380 and 80C
excavators. 8" diameter SDR 35 piping was installed from the recently installed stub out to manhole 4.
De watering was performed as necessary. The piping was bedded in ¾" crushed stone. The trench was
backfilled using imported 2" minus processed gravel consisting of F - C gravel and sand, trace silt. 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. Intermittent inspection
