This is a historical cost estimate report from the Florida Department of Transportation (FDOT) displaying weighted average unit costs for construction and maintenance items based on statewide contract data collected between December 1, 2024, and May 31, 2025. The document serves as a reference tool for estimating costs on the SR 20 and CR 83A West (West Bay Loop) intersection improvements project located west of Freeport, Florida. The project includes construction of intersection improvements consisting of turn lane extensions, multi-use path realignment, concrete traffic separators, resurfacing, drainage improvements, signing, pavement markings, and traffic signalization. The contract duration is 150 days to substantial completion with an additional 30 days for punch list completion. The cost estimate encompasses a comprehensive range of line items across multiple construction categories, including maintenance of traffic ($1,517.76 per day average), temporary traffic control infrastructure, earthwork and excavation, base and pavement materials, concrete work, reinforcing steel, signage and sign structures, and intelligent transportation system (ITS) components such as CCTV cameras, communications equipment, and traffic monitoring systems.

The report presents weighted average unit costs derived from multiple historical contracts, enabling project planners to establish realistic budgeting parameters for the intersection improvements. Pricing is itemized across numerous construction elements, with costs varying significantly based on material type, quantity, and complexity; for example, milling existing asphalt pavement ranges from $2.22 to $18.18 per square yard depending on depth, while overhead static sign structures span from approximately $58,000 to $413,000 per unit depending on cantilever or span configuration. Key infrastructure costs include superpave asphaltic concrete ranging from $135 to $232 per ton, plain and reinforced cement concrete pavement from $127 to $225 per square yard, and various traffic control and signalization components. The data reflects statewide contracting practices under FDOT's standard contract type (CC) and provides essential cost benchmarking information for procurement planning, bid evaluation, and budget allocation for the county-supplied pre-procured signal components and contractor installation requirements outlined in the project specifications.
