About this file

This is a technical drawing sheet (Dt-3: Miscellaneous Notes, Tables & Details) prepared by Greenville County, South Carolina for the Merrifield Park Drainage Improvements project, establishing construction standards and specifications for bid preparation. The project involves installing approximately 2,380 linear feet of storm drainage pipe ranging from 18 to 36 inches in diameter, 24 catch basins and drop inlets, and associated site restoration within the Merrifield Park subdivision off Hudson Road. A mandatory pre-bid meeting is scheduled for July 14, 2026 at 11:30 a.m., with bids due July 24, 2026 at 3:00 p.m. The contract award is tentatively scheduled for August 7, 2026, with Notice to Proceed expected August 12, 2026. The contractor must complete all work within 150 consecutive calendar days from Notice to Proceed. Questions regarding the project are due July 17, 2026 at 2:00 p.m.

The drawing sheet provides detailed specifications for drainage infrastructure construction, including concrete mix requirements (3,000 PSI minimum), curb and inlet installations, catch basin construction, pipe bedding protocols, pavement patching procedures, and temporary erosion control measures. All concrete work must achieve 3,000 PSI minimum compressive strength at 28 days. A bid bond of 5 percent of the total bid price is required at submission, with performance and payment bonds equal to the total bid price due within 15 working days of award. Contractors must maintain comprehensive general liability insurance of $1 million per occurrence and $2 million general aggregate, along with statutory worker's compensation coverage. Liquidated damages are assessed at $150 per calendar day for failure to achieve substantial completion. Award will be made to the lowest responsive bid, with monthly progress payments including 10 percent retainage until satisfactory completion.
