Unit 4 cell 5 earthwork construction twin chimneys landfill

Greenville County is soliciting proposals for the construction of Unit 4 Cell 5 Earthwork at Twin Chimneys Landfill, a municipal solid waste landfill project involving the excavation of approximately 160,000 cubic yards of soil and rock material across 12.5 acres. The project requires contractors to excavate miscellaneous soil, clay, and rock, with materials to be strategically stockpiled in designated on-site locations, including specific areas for clay soils, rock, and miscellaneous soils. Key deliverables include temporary sediment basin decommissioning, installation of three gabion baskets, placement of 2,000 square yards of erosion control blankets, and seeding of 12 acres of disturbed areas. Contractors must demonstrate experience by completing at least two similar projects within the last five years and provide comprehensive documentation, including pre-construction and as-built surveys signed by a licensed land surveyor. The solicitation timeline includes a non-mandatory pre-proposal meeting on January 14, 2026, at 10:30 AM, a question submission deadline of January 19, 2026, at 5:00 PM, and proposal submissions due electronically by February 9, 2026, at 3:00 PM. The evaluation criteria are equally weighted at 20 percent each, assessing responsiveness to the RFP, proposed project schedule, similar project experience, cost, and equipment specifications.

The contract does not specify specific set-aside designations or restrictions for disadvantaged enterprises. Contractors must submit a Bid Bond equal to 5 percent of the bid price and provide Performance and Payment Bonds equal to the total bid price within 15 working days of award. Insurance requirements are comprehensive, including $1,000,000 General Liability per occurrence, $1,000,000 Automobile Liability, Statutory Worker's Compensation, $1,000,000 Umbrella/Excess Liability, and $1,000,000 Professional Errors and Omissions, with Greenville County named as an additional insured. The County anticipates awarding the contract on February 20, 2026, with contract negotiations occurring between February 20 and March 16, 2026, and a targeted Notice to Proceed on March 16, 2026. The project has a substantial completion timeline of 150 days, with liquidated damages of approximately $1,000 per day for substantial completion and $500 per day for final completion. While a specific budget range is not explicitly stated, the project's scope and requirements suggest a significant infrastructure investment for landfill cell development.
