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.

• Upon arrival, the contractor was engaged in performing cuts using a CAT 349E for the Lots #86, 87, 88 and 89. Fill was being transported with tandem dump trucks CAT 745 and with a Komatsu 512PXi. Compaction work was carried out using a CAT 815F sheepsfoot roller.
• Two soil samples were collected and returned to our laboratory to perform a moisture-density relationship (proctor).
• 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 compacted materials appear high in moisture content. As there is no proctor yet available, density and relation to optimum moisture content cannot yet be verified, therefore a proof-roll was performed to check stability.  Proof-roll observation displayed no severe pumping and/or rutting of compacted soils in this area.
