Class 2 landfill partial closure

Greenville County, South Carolina is soliciting proposals under RFP #27027 for partial closure construction of the Class 2 Unit 2 Landfill at the Twin Chimneys Landfill, with questions due October 30, 2026 at 5:00 p.m. and proposals due November 16, 2026 at 3:00 p.m. through the County's online procurement portal.

The scope covers a stormwater pond, subgrade preparation, structural fill for a perimeter berm, a stone access road, and erosion control measures including silt fence, erosion control blankets, seeding, and gabion baskets. The project involves approximately 301,000 cubic yards of excavation and 120,000 cubic yards of structural fill, with the soil borrow area inside the Unit 2 footprint already cleared. Substantial completion is required within 210 calendar days. Contractors must employ a South Carolina-licensed land surveyor for survey control and as-built surveys and engage a South Carolina-licensed firm for soil testing. Drawings were prepared by HDR Engineering, Inc., and the contract documents incorporate EJCDC C-700 (2018) and C-800, with provisions for equitable adjustment if differing site conditions are encountered.

Bid bonds must equal 5% of the bid price and may be in the American Institute of Architects format, Surety 2000 format, or certified check. A performance and payment bond for the total bid price is due within fifteen working days of award. Insurance requirements include comprehensive general liability of $1,000,000 per occurrence and $2,000,000 aggregate, automobile liability of $1,000,000 per occurrence, and statutory workers' compensation, with the County named as additional insured on applicable policies. Vendors must submit Greenville County's Substitute Form W-9, which the County will not accept in place of the standard IRS form.

Evaluation uses six equally weighted criteria at 5 points each: responsiveness to the RFP, experience and past performance, project approach and schedule, pricing, equipment, and references. Pricing must be firm, based on payment in thirty days, and submitted on the Proposal Forms in the Project Manual.

The County has tentatively scheduled award for November 30, 2026, with contract negotiations from November 30 through December 18, 2026, and anticipates issuing Notice to Proceed by December 18, 2026.
