About this file
This Engineers Estimate document prepared for Greenville County, South Carolina outlines the detailed cost breakdowns for two stream restoration and riparian area reclamation projects within the Reedy River watershed. The North Chastain Stream Restoration project encompasses 5.5 acres of reforestation and 1,200 linear feet of stream restoration, while the Little Creek Stream Improvement project involves 6.5 acres of reforestation and 1,400 linear feet of stream restoration. Both projects include comprehensive environmental restoration work such as bank grading, erosion and sediment control, clearing and grubbing, excavation and fill operations, installation of instream features (cross vanes, boulder riffles, and single-arm vanes), bank stabilization treatments (boulder walls, boulder toe installations, and toe rock), turf reinforcement matting applications, and vegetation establishment including live stakes, trees, shrubs, and plugs. The procurement released on December 13, 2024, includes a non-mandatory pre-bid meeting and site visit scheduled for January 3, 2025, with bid submissions due by January 13, 2025, at 3:00 pm. Contract award is anticipated for January 15, 2025, with a Notice to Proceed expected on January 24, 2025, contingent on obtaining all pending permit approvals. The contract includes a one-year plant guarantee period during which the contractor is responsible for plant health, replacement, and site maintenance.
The total Engineers Estimate for both projects is $1,391,916.13, with the North Chastain project estimated at $591,483.83 and the Little Creek project estimated at $800,432.29. Major cost items include mobilization costs of $53,771.26 and $70,380.21 for each project respectively, excavation and grading ranging from $112,539.96 to $146,994.64, and substantial vegetation and matting installations totaling significant portions of each project budget. The project is funded through an ARPA-Funded Stormwater Infrastructure Program (ASIP) grant from the South Carolina Office of Resilience (SCOR). Bidders are required to submit a bid bond equal to 5% of the bid price and provide $1,000,000 in general liability and $1,000,000 in automobile liability insurance. The procurement specifies that all spoil material must be deposited at the Blackberry Valley Residential Waste and Recycling Center with no tipping fees, and that boulders are available at no cost from the Twin Chimneys Landfill. Evaluation criteria include responsiveness, cost, previous experience, and references using a pass/fail scoring method, with no specific set-aside designations or restrictions for disadvantaged enterprises explicitly stated.
