Observations/Finding

At the request of the client’s representative, AS ENGINEERING AND CONSULTING, LLC (ASEC) representative, Isaac Davis visited the job site to observe and monitor the contractor’s work activities from a quality standpoint to assure compliance with project drawings/specifications, applicable codes, and materials submittals and conducted QC testing per the project drawings and specifications.  The following observations were made on site this shift:

• The writer arrived on site to verify the subgrade for the proposed vault 2 generator pad. The generator pad is a 16’ 8” X 11’ 8” section and was excavated to proposed bottom of concrete elevation at this time.
• While probing the ground within the footprint, the writer noted approximately 11 feet 8 inches X 5 feet section on the north side, loose to a depth of approximately 4 to 6 inches.
• The writer recommended this area be remediated by removing the top 6-inches of this section and replacing it with structural fill or #57 stone.
• The contractor chose to replace the under-cut section with # 57 stone. The subgrade is now acceptable and ready for rebar installation.
• The form work and the bottom mat of the pad are being installed.

If you have any questions about our observations or recommendations stated in this report, we will be more than glad to discuss them with you.
