FIELD REPORT
3.75
The undersigned arrived on site, as requested, to observe the compaction of soils for utility
backfill. Please see the attached sketch.
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 and moisture content above OMC as
obtained in our laboratory using the ASTM D 698-12 Method A Standard.
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. Reinforcing Steel observation for Slab on Grade, Pour 3.
After reviewing the applicable structural drawings, reinforcing steel and accessories appeared
to be properly installed.
3. Visual observation of high strength non-shrink grout for Column B-2 base plate.
