OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Footing excavation continued perimeter and interior footings located within the Southeastern
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 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 organic tannin bark or existing urban fill containing
slag, ash, gravel, sand, wood, brick, organic silt and various other debris. Groundwater was well
controlled and de watering was performed as necessary. A 6" 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 # 622 was incidentally broken at an
approximate depth of 33" below sub grade elevation. The area was excavated down to the top of the
broken element and an 18" diameter section of HDPE pipe was placed over the element as a sono tube to
bring the element back up to the required grade with concrete. The repair was coordinated with Jorge
Fuentez of Geopier.
