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 backfill soils for the storm water trench, between MHA2.6, MHA2.6.1, MHA2.6.2, and lot#2, Lot#3, Lot#4, continued this day.
• At the time of arrival, our representative observed that work was in progress with1-foot lifts being placed and compacted using 20 tons pad feet and trench compaction equipment. Compaction testing was performed using a Troxler nuclear density gauge (ASTM D 6936) 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.
