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 pipe crew continued installation of storm line 3.1 to 3.2 to 3.3, as well as sewer line 13.1 to 13.2. Soils were placed in approximate 12-inch lifts and compacted using a sheep-foot and trench roller. Density testing was performed and test results were provided to the contractor. In areas that consisted of a large quantity of rock, visual inspections were performed to confirm that the contractor is properly compacting the line. In areas with large rock quantity, density testing with the nuclear density gauge was not possible, as the nuke gauge pit could not be inserted into the ground.

The grading crew continued to assist the wall crew on the installation of wall 1. Soil was spread in approximately 8-to-12-inch lifts and compacted using a sheep-foot roller. Density testing was performed, and test results were provided to the contractor.

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.
