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 # 106, 107, 108, 109, and the water storm line between MH B1 and MH B2 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 810F 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, several tests did not meet project specifications for compaction.  Our representative discussed this with the contractor and our office, who notified Century of these issues.
• Note: in-situ moisture contents exceeded optimum moisture contents by more than 3 percent on several of the density tests.
