V.P. of Engineering PE # 81439 08/28/20 Email to: andooffice2015@gmail.com 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.
