Mechanical Aquatic Vegetation Shredding

The St. Johns River Water Management District is requesting submittals on mechanical aquatic vegetation shredding services on District-managed properties across eighteen counties in North and South conservation regions, with submittals due July 8, 2026 at 3:00 p.m. and questions due June 30, 2026. Respondents must demonstrate a minimum of three years of experience performing mechanical aquatic vegetation shredding on projects similar in scope and complexity, supported by evidence of three successfully completed similar projects within the last three years.

Heavy-duty shredding equipment must meet minimum specifications: hydraulic-powered rotating blades with a cutting head width of at least ten feet, a power source of minimum 400 horsepower, and capability to operate in water depths as shallow as 24 inches. Light-duty equipment specifications are less stringent and intended for limited-access areas. The District anticipates that the majority of work will use heavy-duty equipment, with light-duty equipment deployed only on a limited basis and when specifically authorized. Work will be authorized on an as-needed basis by the District's Project Manager, who will identify treatment locations and provide site-specific guidance prior to mobilization. For each authorized mobilization, the contractor is guaranteed a minimum of ten billable hours for heavy-duty equipment and five billable hours for light-duty equipment, applied once per project start.

The initial contract term is three years with the option of two annual renewals upon mutual written agreement. The estimated total budget is $200,000 for the initial three-year term; funding for renewal terms will be determined at renewal and is subject to available budgeted funds. All hourly rates on the bid form must be all-inclusive of labor, equipment, materials, mobilization, demobilization, and fuel. Award will be made to the lowest responsive and responsible bidder based on total bid amount. The agreement is funded through the Florida Department of Environmental Protection under CSFA No. 37.022.
