FIELD REPORT
9.92
The undersigned arrived on site, as requested, to observe:
1. The placement and compaction of soils for plumbing backfill.
Utilizing the nuclear test method to check the compaction of soils; test results indicated that the
compacted material, at the areas and elevations tested, met or exceeded the project
requirements of 95% of the maximum dry density as obtained in our laboratory using the
ASTM D 698-12 Method A Standard, with the exceptions of Tests 8 and 9.
Locations and elevations of all tests are based on stakeout provided by others. We cannot be
responsible for structures located off of the observed engineered pad, misaligned utilities or
stakeout errors causing uncontrolled fill to be placed in structural areas.
2. The bearing capacity of soil of Footings B-4 and C-4.
Utilizing a Dynamic Cone Penetrometer (ASTM STP-399) to check the bearing capacity of soil
at the aforementioned locations, test results indicated that soils, at the areas and elevations
tested, should be capable of supporting a foundation designed for a net allowable bearing
capacity 3000 psf.
