FIELD REPORT
4.25
The undersigned arrived on site, as requested, to observe:
1. The placement and compaction of soils for Water 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.
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 Column Footings D-4, E-4, and F-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 of 3000 psf.
3. The placement of 12 cubic yards of 3000 psi concrete for Column Footings B-4, C-4, D-4,
E-4 and F-4.
The required test limits were determined to be a slump of 3-5 inches, air content of 0-3 %,
batch to placement time of 90 minutes, and concrete temperature range of 50-95 degrees
Fahrenheit.

FIELD REPORT
Concrete observed on this date appeared to be placed in compliance with project specifications
with regard to temperature, slump, air content, and batch to placement time.
One set of five laboratory cured concrete cylinders were cast for compressive strength testing in
our laboratory.
