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.

Crew continued working on Lots #62, 63, 64, and the adjacent roadway area. Fill material was placed in lifts, spread using a crawler bulldozer, and compacted using both a sheep-foot roller and a Caterpillar 815. Density tests were performed with a couple of tests initially failing due to high moisture content in the fill material and placement of thick lifts. Our representative recommended the material be replaced at 6 to 8 inches and aerated prior to re-compaction. After re-compaction, additional density tests were performed, and the results met the required project compaction specifications.

At Retaining Wall 5, the crew continued installation of CMU blocks by leveling the sub-grade and placing No. 57 stone. The blocks appeared to be installed in accordance with the project plans. Fill material was then placed in controlled lifts and compacted using both a double drum roller and a sheep-foot roller.

At the Buford neighborhood site, the crew continued trench excavation using a hydraulic excavator equipped with a rock grinder.
