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 #145, 146, 147, 148, 149,189, 195, 196, 197, 239, 240, 241, 242, 243 and work was on progress for storm water trench between MH C4 to MH C5 and MH C6, and also work was on progress for sewer trench between MH A11 and MH D1, continued this day.
• At the time of arrival, the contractor had already placed soils for the lifts placed for Lots #189, 195, 196 and 197. Our representative observed other lots where 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 requires recompaction and retesting.  The contractor was notified.
