CR 395 North Road Reconstruction Multi-Use Path Project - Construction Cost Summary
This is an Estimate of Probable Construction Cost (EOPC) document prepared by Walton County, Florida for the CR 395 North Road Reconstruction Multi-Use Path Project (Invitation to Bid #25-23) located in Santa Rosa Beach. The project encompasses comprehensive road reconstruction, resurfacing, and construction of a new 10-foot wide asphalt multi-use path along approximately 7,200 linear feet of County Road 395 North. The scope includes extensive site preparation involving clearing and grubbing (2.32 acres), earthwork including over-excavation and demucking, installation of 1,309 linear feet of new drainage pipe, 1,522 linear feet of 18-inch ADS pipe, multiple inlet installations, timber retaining walls (1,064 linear feet), and various pavement improvements including 2-inch Superpave asphalt concrete for the multi-use path (830 tons), 1.5-inch and 1.25-inch Superpave asphalt for roadway sections (1,460 and 1,290 tons respectively), and 2-inch Superpave asphalt for driveway areas (788 tons). Additional work includes asphalt overlay operations, saw cutting and demolition of existing pavement and brick pavers, installation of thermoplastic pavement markings and signage, relocation of utilities including mailboxes, signs, water valves, fire hydrants, and force main valves, sediment barriers, hydro-seeding (24,667 square yards), and sodding (16,444 square yards). The contract duration is 365 days for substantial completion with an additional 30 days for punch list completion. A non-mandatory pre-bid conference is scheduled for September 8, 2025, at 8:30 am, with bid responses due by October 1, 2025, at 3:30 pm.
The estimated total construction cost is $3,359,370.57, comprised of a construction cost subtotal of $3,139,598.67 plus bonds (maximum 2% of bid totaling $62,791.97) and mobilization (maximum 5% of bid totaling $156,979.93). Bidders must be Florida Department of Transportation (FDOT) prequalified in specific work classes including drainage, flexible paving, grading, grassing, pavement marking, and roadway signage. A mandatory 5% bid security is required. Liquidated damages are assessed at $2,667 per day for failure to achieve substantial completion and $1,333 per day for final completion delays. The procurement does not specify explicit set-aside designations for disadvantaged enterprises. Environmental permits from the Northwest Florida Water Management District and Florida Department of Environmental Protection are already secured, including provisions for wetland mitigation through the purchase of 0.56 credits from the Nokuse Plantation Mitigation Bank; the project will impact approximately 0.922 acres of wetlands. The project will be funded through the county's annual appropriation, with specific funding sources not detailed in the contract documents. Walton County reserves the right to reject any or all bids.
