Thomas Marine Construction was founded in 1982 by its former owner, Dean C Thomas, PE. The company has been based at 8999 High Cotton Lane, Fort Myers, FL since its first permanent office was built in 1985. In 2007 Dean Thomas, wishing to retire, sold the stock in the Florida Corporation that is Thomas Marine Construction to Owen Ames Kimball Company in a carefully arranged transaction that allowed TMC’s day to day operation to continue unchanged. The match was ideally suited.

Our History


Thomas Marine has done hundreds of municipal bridges structures for FDOT, several counties, and cities. The work includes overpasses, bridges over natural rivers, over canals, and spanning wetlands.



Many private developments require bridges for property access, internal waterway crossings, or simply as a specific architectural item. TMC has built more than 25 different private bridges for developers.

Water Control

Water Control

Flood control and water retention is a major governmental function in our work range. TMC has constructed many types of structures from large flood control SFWMD structures to smaller weirs.



Of the variety of the pedestrian bridges TMC has constructed for both public and private entities, the majority are steel truss structures. Premanufactured steel truss bridges are a good choice in SWFL



Custom structural projects arise which require some "out of the box" thinking. Thomas Marine has tackled many such projects with success. Toll plazas, tunnels, sheet pile cofferdams and more.

Full Service Bridge & Structural Constructor

Thomas Marine Construction is a full service bridge and structural constructor. Each of the division’s crews is led by a superintendent with a range of experience from 10 to 30 years.

Since 1982, TMC has constructed bridges, built complex water control structures, dredged waterways, and constructed structures across all of the Southwest Florida area for nearly every governmental body (local, state, and federal) and many private companies throughout our geographic area.

The company’s employees include project managers, engineers, carpenters, equipment operators, laborers, mechanical support, accounting staff, and an EEO officer. Many of our people have been employed by the company for 10-25 years.

Thomas Marine Construction owns all the equipment (many shown in photos on this site) needed to construct the work for which it is prequalified. The list of equipment on our job sites every day including: track and truck friction cranes, pile hammers, sheet pile hammers, bridge deck screed machines, excavators, a long stick excavator, a demolition hammer, front end loaders, compaction equipment, specialized steel and modular forms, sectional barges, trucks, welders, and generators.

Each crew is a self-sufficient entity which could be working miles from the nearest power source or in the middle of town.

Even when projects are not design build, Thomas Marine's "whole project approach" enables the company to foresee permitting and design challenges in the planning stage, thus avoiding costly changes once construction is underway.


On many of the projects Thomas Marine has constructed, the company's involvement and assistance began at the concept phase and worked all the way through final construction.

The company is run by civil engineers and as such has been successful at many design build projects and other nontraditional contracting methodologies.
