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 Lots #131, 132, 133, 145, 146, 147, 171, 170, 169, 168 and the sewer trench between MH A10 to C1 and the storm water trench between MH C2 to MH C3 and storm line between A2 to A3, 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 815F and CP56B 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 the compacted materials met the project requirement of 95% of a maximum dry density obtained by a Standard Proctor ASTM 698.  
• Note: one test for backfill at the sewer trench between MH A10 and C1, did not meet the project requirement of 95%.  Contractor was informed to aerate and recompact.
