As requested, we tested the compacted fill for the house pad.
To determine if the fill was properly compacted on the pad to a depth of 4 feet,we performed nuclear density
tests on the top two feet.To estimate the soil density below a depth of 2 feet we used a Static Cone
Penetrometer.During the tests,a shaft with a conical point is pushed through soil and the soil resistance
measured on a calibrated gauge.After the soil resistance is measured,the hole is advanced with a hand-auger in
1-foot increments to permit a continuation of measurement of density versus depth.
Test Results:
Nuclear density tests performed on the top 2 feet indicates the compaction exceeds the project specifications of
95%(ASTM 1557).Static Cone Penetrometer readings indicate the compacted backfill below 2 feet are generally
well compacted to a depth of 4 feet.
Based on the nuclear density tests and Static Cone Penetrometer readings,it appears the fill on the house pad
was properly compacted.
