About this file
This document is an Opinion of Probable Construction Cost (OPC) for the CR 183S Cross Drain Replacement project in Florida, dated October 2024. The project involves replacing an existing cross-drain on CR 183 South at Spears Branch, with a contract duration of 120 days for substantial completion and an additional 30 days for punch list completion. The detailed cost estimate includes 28 line items covering roadway construction activities such as mobilization, maintenance of traffic, sediment barriers, excavation, embankment, stabilization, asphalt work, concrete culverts and retaining walls, reinforcing steel, curbing, riprap, guardrail installation, performance turf, and pavement markings.
The total estimated project cost is $685,167.83, which includes a 10% contingency of $62,287.98 on top of the base construction costs of $622,879.84. Unit prices were developed using Florida Department of Transportation (FDOT) 12-month and 6-month moving statewide and area averages for cost information published between May 2023 and July 2024. The opinion of probable construction cost explicitly does not include utility improvements, relocations, or right-of-way acquisition costs. The engineer notes that the cost estimate represents their professional judgment based on current information and cannot guarantee that actual construction costs will precisely match the estimated figures.
