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.

On the above date our representative observed the grading contractor continue subgrade prep at Nature Walk Parkway between sanitary sewer manholes #4 and #9. The subgrade was undercut on an average of -2.5 ‘ to -3.0’ below design elevation. The in-place fill subgrade soils appeared stable under truck traffic. The writer also observed RCP storm pipe installation at the bridge embankment placed between HW #B1 and manholes B1A to B1B. The writer recommended using compacting equipment on backfill at the sides and over pipe.

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.
