OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Footing excavation continued 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. GCC # 599 was incidentally broken at an approximate
depth of 18" below sub grade elevation. The area was excavated down to the top of the broken element
and backfilled to sub grade elevation with compacted structural fill. Repairs were coordinated with
Jorge Fuentez of Geopier.
Installation of drainage utilities continued at the southwest side of building 1. The trench was
carried down to design elevation utilizing the Deere 380 excavator. Piping was installed connecting DMH
13 and DMH 12. CB 10 & 11 were also connected to previously installed DMH 13. The 12" diameter HDPE
piping was installed and bedded ¾ up the pipe in ¾" crushed stone. The remaining bedding/backfill

material used is the same material generated during excavation generally consisting of F - C gravel and
