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 for the storm trench from MHA0, MHB1, MHB2 and MHB3, sewer trench between existing MH to front of building, 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 a 9-ton sheeps-foot and trench compactors. Compaction testing was performed using a Troxler nuclear density gauge of Soil (ASTM D 2937), 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.
• Note: contractor used soils with various diameter of rock embedded (see attached photos).
