CLASS 2 LANDFILL PARTIAL CLOSURE
Solicitation # 27027
The County of Greenville is soliciting proposals for the partial closure construction of the Class 2 Unit 2 Landfill at the Twin Chimneys Landfill in South Carolina. The scope of work involves significant earthwork, including approximately 301,000 cubic yards of excavation and 120,000 cubic yards of structural fill for a perimeter berm. Key deliverables include the construction of a stormwater pond, subgrade preparation, stone access roads, and the implementation of erosion control measures such as silt fencing, seeding, and gabion baskets. The project requires the contractor to provide a South Carolina-licensed land surveyor for as-built surveys and a licensed firm for soil testing. The County desires substantial completion within 210 calendar days, with a tentative Notice to Proceed date of December 18, 2026. Proposals are due by November 16, 2026, and will be evaluated on a point system covering responsiveness, experience, project approach, pricing, equipment, and references. Award decisions will heavily weigh integrity, reputation, and past performance. The contract requires a bid bond as well as performance and payment bonds equal to the contract price, remaining in effect for one year after final payment. Quality control is a dual-layered process where the contractor manages Construction Quality Control (CQC) through an independent laboratory, while the Owner performs Construction Quality Assurance (CQA) through a separate licensed firm. Payment is based on a mix of lump sum and unit price items, with undisputed invoices due upon receipt and subject to a non-appropriation clause.
