FIELD REPORT
5.50
The undersigned arrived on site, as requested, to observe:
1. The compaction of soils for Lot 5 and Lot 6 12" Water Line from STA 5+10 to 7+50. 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, DID NOT MEET or exceeded the
project requirements of 95% of the maximum dry density with a moisture content above
optimum, as obtained in our laboratory using the Standard Proctor Method (ASTM D-698).
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.
The superintendent was informed of the failing density tests.
2. The placement of 4000 psi concrete for Lot 2R Storm Drain Line 7 Y-Inlet Tops and Aprons
at STA 0+93 and STA 1+86, and Storm Drain Line 5 Y-Inlet Top and Apron. Please see the
attached sketches.
The required test limits were determined to be a slump of 3-5 inches, air content of 3-6 %,
batch to placement time of 90 minutes, and concrete temperature range of 55-90 degrees
Fahrenheit.
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
