Cone & Graham

What Cone & Graham does

Cone & Graham, Inc. is a privately held, Florida-focused heavy civil construction company founded in 1979 and headquartered in Tampa, with a regional office in Port St. Lucie. The firm specializes in road and bridge construction, design-build project delivery, marine construction, and aviation infrastructure, employing more than 200 dedicated staff across the East and West coasts of Florida. Its core service portfolio comprises Heavy Highway Construction, Bridges, Design-Build, Marine Construction, and Aviation Infrastructure, delivered primarily to government clients including the Florida Department of Transportation (FDOT), Hillsborough County Aviation Authority, and county and municipal governments across Pasco, Hillsborough, Martin, Polk, and Manatee Counties.

The company's underlying capabilities rest on specialized technical execution rather than proprietary software, including the deployment of 84-foot Florida I-Beams spanning 185 feet and the construction of Florida's first LEED Silver Certified weigh station facility. Cone & Graham pursues work through competitive bidding on public infrastructure tenders and integrates design partners — notably Wantman Group (WGI), Kimley-Horn, WSP, and KCA — into long-term design-build teams. The business model is project-based, one-time construction contracting with multi-year durations and contract values ranging from approximately $0.6 million to $95 million; examples include the Ridge Road Extension ($95M), SR 56 Extension ($60M), Dixie Highway Flyover ($32M), and Big John Monahan Bridge Replacement ($32M).

Revenue is earned as work progresses on defined scopes with specified completion timelines, and the company is differentiated by documented cost and schedule outcomes (e.g., Big John Monahan delivered 104 days early with $25.8M in savings and a perfect CPPR of 110; Ridge Road achieved 83% wetland impact reduction). The firm is privately held with no disclosed institutional investment, no subsidiaries, no M&A activity, and no publicly reported revenue. Marketing is limited to a project-portfolio website and industry awards (DBIA Florida, FICE, SEAA, FTBA), consistent with a government-contractor business model driven by prequalification, past performance, and design-build partnerships.
