Thomas Marine Construction

What Thomas Marine Construction does

Thomas Marine Construction is a Fort Myers, Florida-based civil construction contractor founded in 1982 by Dean C. Thomas, PE. The firm builds public and commercial bridges, water control structures, roadways, and supporting site work across Southwest Florida. Its core service offerings are organized into five lines: Public Bridges (FDOT and municipal), Private Bridges (custom design, permitting, and construction for developers and property owners), Water Control Structures (flood control and retention), Site Work (earthwork and environmental restoration), and Roadways (self-performed roadway and drainage). The company is FDOT-prequalified for projects of all sizes and supports prime, subcontractor, and design-build delivery models. Vertical integration across earthwork, bridge, drainage, and roadway phases allows the firm to act as a single-source contractor on most projects.

The company operates primarily in Southwest Florida, serving FDOT, county and municipal governments (Lee, Collier, Charlotte, Sarasota, Polk), water management districts (South Florida and Southwest Florida), and the Army Corps of Engineers on the public side, alongside national residential developers including Pulte Homes, Lennar/US Home, Minto Communities, Toll Brothers, Stock Development, Barron Collier, and Kitson Partners-Babcock Ranch on the private side. Revenue is generated through competitive bidding on fixed-scope construction contracts; pricing is project-specific and not publicly disclosed.

Since 2007, Thomas Marine Construction has been a subsidiary of Owen-Ames-Kimball, an employee-owned construction company founded in 1891. The parent provides bonding capacity, insurance, and back-office resources that exceed what a firm of TMC's size could independently secure. Day-to-day operations and company culture have been preserved under the parent relationship. The firm has delivered hundreds of municipal bridge projects and more than 25 custom private bridges, and received the FDOT Rural Project of the Year recognition for the SR 72 bridge over Horse Creek.

Direct peers

• Anderson Columbia Co. Florida-based heavy civil contractor performing road, bridge, and site work across the state. Most direct comparable peer given shared FDOT-prequalified public infrastructure focus in Florida.
• C.W. Roberts Contracting: Florida-focused heavy civil and site development contractor performing roadway and infrastructure work. Comparable as a regional FDOT-eligible civil contractor.
• Ranger Construction Industries: Florida-based heavy civil and paving contractor with FDOT and municipal project focus. Comparable regional competitor for roadway, drainage, and bridge-adjacent civil work.
• Prince Contracting LLC: Florida-headquartered heavy civil and bridge contractor pursuing FDOT, county, and private developer projects. Comparable mid-sized competitor competing for similar bridge and roadway bids.
• Superior Construction Company: Heavy civil and bridge contractor with strong Florida operations including FDOT work. Comparable in scope across bridges, highways, and civil structures.

Broad incumbents

• Hubbard Construction Company: Large Florida-based heavy civil contractor (now part of OHLA) executing major highway, bridge, and site development projects. Larger incumbent that competes for the same FDOT and developer work but at a broader scale.

• Kiewit Infrastructure: One of North America's largest heavy civil contractors with active Florida bridge and infrastructure operations. Competes for large FDOT mega-projects that TMC also targets as a subcontractor or smaller prime.
• Archer Western (Granite Construction): Major heavy civil and bridge builder with established Florida presence pursuing large FDOT and transportation authority projects. Larger incumbent competing for shared end customers.
