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 retaining wall 6 continued today.
• At the time of arrival, our representative observed that work was in progress with one (1) foot lifts and compacted using a sheeps-foot compactor.
• Probe rod tests were conducted in several places, including the decel lane and around utility backfill.  Soft areas were undercut 6 feet and replaced with GAB (graded aggregate base).
• Density test results indicate that the compacted materials met the project requirement of 90% of the maximum dry density obtained by the (Standard Proctor ASTM 698).
• Observed the placement 110 cubic yards of 3000 psi concrete for retaining wall 9 footing (location shown in pictures).
