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 assure compliance with project drawing/specifications, applicable codes, and materials submittals. The following observations were observed on site this day.

The placement and compaction of backfill soils for Storm trench between MH15 to MH16 and MH17, also Backfill for Retaining wall B, and  Backfill for lots 26 and 27,continued this day.

At the time of arrival, our representative observed that work was in progress for Storm trench with approximately one (1) foot lifts being placed at finished grade and compacted using a C5P734 compactor and for retaining wall B using 11-ton pad feet compactor.

Density test results indicate that the compacted materials met the project requirement of 95% for retaining wall B, and 90% for Storm trench, of the maximum dry density obtained by the (Standard Proctor ASTM 698),
