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 in the installation of retaining wall 1. Soil lifts were spread approximately 8 to 12 inches in thickness and compacted using a vibrating sheep-foot roller. Density testing was performed and test results were provided to the contractor. The contractor undercut approximately 3 feet deep x 4 feet wide x 75 feet long to replace with No. 57 stone and a 6-inch GAB cap in the failed portion of the footing for retaining wall 1. It was recommended to excavate 2 feet deep, but the contractor over excavated the area. Additional No. 57 stone was needed to fill the trench to the final grade of the footing.

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.
