Observations/Finding

As requested, the site was visited by our AS Engineering and Consulting (ASEC) representative for the purpose of providing quality control inspection and testing services. Visual observation techniques were employed to verify compliance with project drawing/specifications, applicable codes, and materials submittals. The following observations were observed on site this day.

At Retaining Wall 5, Dynamic Cone Penetrometer (DCP) tests were performed to evaluate the sub-grade soil bearing pressures.

Test 1 (Red Silty Sand Clay):

1st foot – 9 blows, 2 feet – 11 blows, 3 feet – 11 blows, 4 feet – 10 blows

Test 2 (Red Silty Sand Clay):

1st foot – 8 blows, 2 feet – 9 blows, 3 feet – 10 blows, 4 feet – 9 blows

At the Buford neighborhood site, the crew began work at the manhole by installing a corrugated HDPE sleeve (encasement) around the vertical DIP pipe. Gravel was placed within the sleeve to. Temporary backfill material was then placed around the pipe and structure to provide initial stability, with further compaction and final backfilling to be completed in subsequent operations.
