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.

Our ASEC representative was on site to observe the contractor (NG Grading) and for the observation/testing of the placement of fill/backfill.

The grading crew continued to assist the wall crew with installation of retaining wall 1. Soil lifts were spread across the wall and lots above retaining wall 1 in approximately 8-to-12-inch lifts. The lifts were compacted using a vibrating sheep-foot roller. Density testing was performed and test results were provided to the contractor. ASEC watched as loaded trucks rolled across the lifts to check for stability. There were no signs of severe pumping or deflection present.

The pipe crew is de-mucking the detention ponds and placing stone in the bottom of the ponds. The contractors are installing BA-9. Backfill material contains a large quantity of PWR and blasted rock mixed with finer material. At this time, the contractor has not backfilled over the pipeline enough to perform density testing.

We appreciate the opportunity to be of service to you on this project. If you have any questions regarding this report, please feel free to contact us. We will be more than happy to discuss it with you.
