Observations/Finding

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 SANY SY365LC equipment to excavate a trench from MH 6.9 – 6.11 (205.3 + 34.7+ 32 + 153.2). PVC sanitary sewer laterals were then placed. A CAT 938K was used to transport No. 57 stone and GAB. No. 57 stone was added to 6 inches above the sanitary sewer lateral.  GAB and backfill was added from MH 6.9 – 6.11 and compacted with a walk behind roller.

Our representative observed a CAT 3314 excavator place laterals between MH 1.5 – 1.6 and place sewer laterals. A CAT 938K loader was used to transport No. 57 stone and GAB. No. 57 stone was added to 6 inches above the sanitary sewer lateral.  GAB and backfill was added from MH 1.5 – 1.6 and compacted with a walk behind roller.

A CAT 3151 placed water line between Lots #86 alongside the roadway. Contractors also performed demolition, removed sewer pipes between Lots #45 – 46.
