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 on site this shift:

Our representative observed the contractor use a CAT 336 and CAT 3151 to excavate a water main and 1-foot riser to manholes. A Sany SY365C was used to excavate sewer trench from MH 6.9-6.10. A Sany SY365C was used to place 26-feet of SDR Sewer laterals. Contractors used a CAT 938k loader to transport No. 57 stone and GAB. No. 57 stone was added to 6 inches above the sanitary sewer later. GAB and backfill was added from MH 9.0-10.0 and compacted using a walk behind roller.

A Komatsu 61pxi dozer was used to compact and form Lots #16 through #18. A walk-behind roller was used to compact soil in 6-inch lifts.
