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 assure compliance with project drawing/specifications, applicable codes, and materials submittals. The following observations were observed on site this day:

A request was made for subgrade soils testing on an approximate 17′ x 17′ slab (see photo) located in the far southeast of the project.  Upon arrival our representative observed that graded aggregate base (GAB) had already been placed and was not tested.  Our representative excavated down through the GAB to perform a Dynamic Cone Penetrometer (DCP) test in the approximate center of the slab.

1st foot – GAB (not tested)

2nd foot – 20 blows- soils were visually identified as a red sandy silt

3rd foot – 20 blows – soils were visually identified as a red sandy silt

4th foot – 20 blows – soils were visually identified as a brown silty sand

No nuclear gauge density testing could be performed.
