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 the writer was on site to observe proof-rolling of sub grade soils for the west side relocation lane between station 0+00 and 5+00 using a loaded tandem dump truck loaded with 18.5 tons of base rock. Most areas appeared stable under traffic with some isolated areas marked for repair to
be undercut approximately 10 inches and replaced with additional base stone. The total areas for undercut measured was (10’x18’x12″, 90’x 15’x10″, 90’x 15’x10″, 30’x7’x10″, 35’x10’x8″, 15’x8’x8″, 40’x6’x8″).

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.
