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.

• The placement and compaction of fill soils for Lots #239, 240, 241, 242, 243, 145, 146, 146, 147, 148, 149, storm water trench backfill for MH A5 to MH A6, and between MH C3 and MH C4 and sewer trench between MH A11 to MHC4, continued this day.
• At the time of arrival, our representative observed that work was in progress with 1-foot lifts being placed and compacted using CP56B and 815F and trench compaction equipment.  Compaction testing was performed using a Troxler nuclear density gauge, along with general probing using a 3/8″ diameter probe rod.
• Density test results indicate that most of the compacted materials met the project requirement of 95% of the maximum dry density obtained by a Standard Proctor ASTM 698.  However, 1 test did not meet job specifications for compaction and required recompaction and retesting.  The contractor was notified.
