Summaryof Services Performed (field test data, locations, elevations & depths are estimates) & Individuals Contacted.
The undersigned arrived on site, as requested, to observe the compaction of soils for inside the
Building Pad, Pour Strips and removed sections of Slab on Grade.
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 drydensityas obtained in our laboratoryusing the
Standard Proctor Method (ASTM D698).
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.
