At the request of the client’s representative, our AS ENGINEERING AND CONSULTING, LLC (ASEC) representative visited the job site to observe the contractor’s work activities from a quality standpoint to verify 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:

Contractor then used a CAT 315F to place sewer laterals and added No. 57 stone to 6 inches above pipe. Contractor then used a heavy-duty dump truck to transport GAB to the newly placed sewer. Contractor added GAB and backfill from MH 4.9-4.10 and compacted the trench with a walk-behind roller.
