Observations/Finding

As requested, an ASEC representative visited the project site from 09:30 AM to 06:30 PM to provide quality control inspection and testing services. Visual observation techniques were employed to verify compliance with project drawings, specifications, applicable codes, and approved material submittals.

The drilling work between Manhole 9A and A10 was in progress by Advance Explosive contractor. Three drilling machines were engaged in the operation. The holes were drilled at approximately 7 ft × 7 ft spacing using a 3.5-inch bit. Depth checks were randomly performed and verified against the drill operator’s log sheet.

A total of 48 holes at a depth of  26ft, 10 holes at a depth of 25 ft, and 18 holes at 30 ft were drilled. The rock was encountered at depths ranging from 0 ft to 9 ft.

The embankment work was ongoing in Lots #8, #9, and #10, at approximate elevations ranging from -2 ft to finish grade. Three nuclear gauge tests were performed in Lots #8, #9, and #10.
