This is an Engineer's Estimate document for the Cripple Creek Stream Improvement and Riparian Area Reclamation (SCIIP) project, a stream restoration initiative by Greenville County, South Carolina. The 800-foot stream restoration project addresses erosion mitigation within the Reedy River watershed through comprehensive ecological and structural improvements. Key work items include clearing and grubbing (1.5 acres), excavation and grading (3,750 cubic yards total), installation of instream features such as cross vanes (2 each), single arm vanes (2 each), boulder riffles (4 each), and various bank toe treatments totaling 1,500 linear feet. Additional components encompass turf reinforcement matting installation (4,300 square yards), seeding and vegetation establishment (1.5 acres), live stakes (80 bundles), and plugs/bare root stems (400 each). The project includes mandatory pre-bid site visits and meetings scheduled for July 11, 2025, with bid submissions due August 1, 2025, at 3:15 pm. The anticipated contract award date is September 8, 2025, with a 90-calendar day completion timeline and potential liquidated damages of $250 per day for late completion.

The engineer's estimate totals $706,259.40, including mobilization ($61,148), erosion and sediment control ($28,400), as-builts ($7,500), and a 5% contingency ($33,631.40). Evaluation criteria heavily emphasize cost at 99% of scoring, with only 1% allocated to responsiveness. Bidders must provide a 5% bid bond and maintain performance and payment bonds, along with comprehensive insurance coverage including $1,000,000 in general liability and automobile liability. The project offers significant cost-saving opportunities, including free boulder materials from the Twin Chimneys Landfill stockpile and no tipping fees for spoil material disposal. Contractors must demonstrate experience with similar stream restoration projects and provide references. Federal and state regulations apply, including compliance with the Illegal Immigration Reform Act, though no specific set-aside designations for disadvantaged enterprises are explicitly indicated.
