Upon arrival at the site, backfilling activities were underway for the sanitation sewer. Contractors used CAT Excavators 336 and 315F and heavy-duty dump trucks. Backfilling was performed in 2-foot lifts between manholes 4.9 and 4.10. Contractor added No. 57 stone to 6 inches above the pipe. A walk behind roller was then used for compaction.
