The compaction of soils for Utility Line 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 and moisture content above OMC as obtained in our laboratory using the ASTM D 698-12 Method A Standard, with the exception of Test 13 and 14. 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 1.
