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 was on site to observe the pipe contractor continue backfilling 8″ PVC sanitary sewer line between manholes #14, 15 and 16 along B line. The backfill consisted of smaller rockfill fragments from the recent blast. The rockfill was place in suitable compacted lifts with finer soils mixed and compacted using a vibratory sheep-foot roller. The fill placement was probed using a rounded end steel rod and appeared compacted suitable for rockfill placement. The fill placement was observed at elevation -4.5 feet and approved for additional lift placement.

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.
