About this file
This is an Opinion of Probable Construction Cost document for the Ross Marler Park parking expansion project, prepared for the Board of County Commissioners of Okaloosa County, Florida, Tourist Development Department. The project involves expanding parking capacity at Marler Park with 113 additional parking spaces in anticipation of a new splashpad facility. The scope of work encompasses site preparation and demolition activities including milling existing pavement (706 square yards), demolishing brick (117 square yards), sidewalk (265 square yards), and curbing (309 square yards), along with fence removal, wood post demolition, and tree removal (31 trees). Additionally, the project includes rough grading for a pond (122 cubic yards) and parking areas (330 cubic yards), installation of new asphalt pavement (422 tons), concrete curb (1,550 linear feet), concrete sidewalk (278 square yards), stormwater infrastructure including 18-inch RCP storm pipe (62 linear feet), relocated light poles with junction boxes (8 units), and related site improvements such as wheel stops, silt fencing, and pavement markings.
The subtotal construction cost is estimated at $610,014.52, with a 15 percent contingency of $91,502.18, resulting in a grand total of $701,516.70. Cost data is derived from FDOT Historical Costs for Okaloosa County and statewide data current between March 1, 2025, and February 28, 2026. The estimate explicitly excludes contractor operating costs and profits, permit fees, and bonds. Mobilization costs are estimated at approximately 10 percent of total project cost ($55,000). Notable line items include tree removal ($44,577.69), new asphalt pavement ($72,412.96), optional base material ($91,976.48), relocated light poles ($80,000.00), and concrete curb installation ($55,195.50).
