About this file
This is an Engineer's Estimate of Probable Cost prepared by Crawford, Murphy & Tilly, Inc. for Flagler County, Florida's First Avenue Drainage Improvements Project. The estimate details a comprehensive roadside drainage construction project spanning approximately 0.243 miles along First Avenue from Malacompra Road to the northern dead end. The scope of work includes clearing and grubbing, excavation, installation of storm sewer pipe ranging from 18 inches to 36 inches in diameter, drainage structures and inlets, conveyance swales, embankment work, asphalt paving, concrete driveways, utility fixture relocations, thermoplastic markings, and resurfacing at the First Avenue and Malacompra Road intersection. A non-mandatory pre-bid meeting is scheduled for July 1, 2026 at 11:00 a.m., with written questions due July 9, 2026 at 12:00 p.m., final addenda issued by July 16, 2026, and bids due July 29, 2026 at 2:00 p.m. The contract completion period is 120 calendar days from Notice to Proceed.
The cost estimate uses FDOT Historical Item Average Costs for Area 7 dated February 1, 2025 through January 31, 2026. The estimate includes mobilization at $61,624.53 (10% of total cost), traffic control at $37,304.46 (7% of construction cost), and itemized costs for materials and labor including pipe culverts, inlets, asphalt paving, excavation, and related drainage infrastructure. The successful contractor must be prequalified by the Florida Department of Transportation in major classes of work including Flexible Paving, Hot Plant-Mixed Bituminous Courses, Drainage, and Grading, and must furnish Performance and Payment Bonds equal to at least 100% of the contract price, a one-year Warranty Bond, and maintain Commercial General Liability coverage of $5 million annual general aggregate and Automobile Liability of $1 million combined single limit. The project is subject to Environmental Resource Permit 168205-2 issued by the St. Johns River Water Management District, and bids must remain firm for 90 days after opening.
