About this file
This is a revised proposal form for Addendum 1 issued by Greenville County, South Carolina for the construction of Unit 4 Cell 5 Earthwork at Twin Chimneys Landfill, a municipal solid waste facility. The project involves excavation of approximately 185,000 cubic yards of material (miscellaneous soil, clay, and rock) and placement of structural fill across 12.5 acres. Major work items include bonds and insurance, construction quality control, survey and control, crushing and hauling existing surface rock (300 cubic yards), clearing and grubbing (1.3 acres), erosion and sediment control, excavation of miscellaneous soil (167,000 cubic yards), clay (10,000 cubic yards), and rock (8,000 cubic yards), structural fill placement (7,500 cubic yards), temporary sediment basin decommissioning, access road installation with geotextile (4,750 square yards) and stone (3,100 tons), erosion control matting (3,000 square yards), and seeding (12 acres). The non-mandatory pre-proposal meeting was scheduled for January 14, 2026 at 10:30 AM, with questions due by January 19, 2026 at 5:00 PM, and proposals due electronically by February 9, 2026 at 3:00 PM. Contract award is anticipated for February 20, 2026, with contract negotiations 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.
Pricing is based on a combination of lump sum and unit price items, with proposers responsible for independently verifying quantities rather than relying on engineer estimates. For lump sum items modified during construction, the adjustment methodology involves dividing the lump sum bid by the engineer's estimated quantity to establish a unit price. A Bid Bond equal to 5 percent of the bid price and Performance and Payment Bonds equal to the total bid price are required within 15 working days of award. Insurance requirements include $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. Evaluation criteria are equally weighted at 20 percent each and include responsiveness to the RFP, proposed project schedule, similar project experience (requiring at least two completed similar projects within the last five years), cost, and equipment specifications. No specific set-asides or restrictions for disadvantaged enterprises are designated. Proposers must provide unit prices consistent with typical industry norms and justify any prices appearing inconsistent with similar work, with failure to do so potentially rendering the proposal non-responsive.
