OBSERVATIONS:
This report follows a site visit to observe/test the earthwork for: Footing trench excavation.
Interior footing excavation was performed within the limits of proposed building #2 specifically
footing location F/10 (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 elements were previously excavated to design cutoff elevation. 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
urban fill containing wood, ash, brick, slag etc. A layer of Mirafi 160 filter fabric was placed atop
the sub grade. A 6 - 12" 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.
Pavement sub grade filling continued within the NE project limits. The material used is an onsite
generated urban fill consisting of F - C gravel and sand, little silt containing various debris such as
wood, brick, slag, ash, glass, metal, organics ETC. The material was also recently tested for organic
content and was shown to contain 11.3% organic material content. The material was recommended to be
amended to achieve a reasonable organic content. The site contractor was directed to use the material
to finished sub grade elevation in pavement areas without amendments despite the recommendations of the
geotechnical engineer. 12 - 18" thick lifts were placed and graded utilizing the Deere D6 bulldozer.
Each lift was compacted utilizing the IR 10 ton drum roller. Some minor rutting and weaving conditions
