Summaryof Services Performed (field test data, locations, elevations & depths are estimates) & Individuals Contacted.
The undersigned arrived on site, as requested, to observe:
1. The compaction of soils for Fire Lane and Ramp.
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% compaction, OMC +2%) for Ramp
- did not meet the project requirements (95% compaction, +OMC) for Fire Lane subgrade.
Locations and elevations of all tests are based on stakeout provided byothers. 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 installation of reinforcing steel at wall footing.
There was a section without anyreinforcing steel at time of observations. The project
superintendent was notified. Please see the attached photos.
