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 proof-rolling of subgrade base stone after previous repairs was supposedly completed. The writer observed the east, west lane addition using a loaded tandem dump truck making two passes over all areas. The proof-roll at the added lane appeared stable under traffic and was ready for additional base stone placement. Also, the deceleration lane and drive entrance was observed of which four isolated areas were observed to have moderate to severe movement under traffic with previous recommendations made that was followed. At the east half decel lane it was recommended to remove in place base stone and undercut saturated in-place subgrade soils and replace with additional base stone. The contractor attempted to aerate the saturated subgrade soils which did not work (also alone curb line at drive exit lane). The areas listed below were marked with paint and recommended for repair.

1.11′ x 8′ – right side of entrance drive

2.13′ x 11′- right side at exit turn

3.4′ x 40′ – along curb line at exit drive

4.70′ x 12′ – east half of decel lane
