C J Mahan Construction Company LLC: Your Gateway to Marine Careers

About Us

Based in Columbus, Ohio, C.J. Mahan Construction Company, LLC is a heavy-civil and marine contractor with a proven track-record for success on some of the most challenging and complex infrastructure projects east of the Mississippi.

Perhaps best known for our expertise in major bridge structures, Mahan has nearly forty years of experience in the design and construction of a wide range of bridge types, including welded steel girder, cable-stayed steel and concrete, long-span steel truss, railroad, precast concrete, and concrete segmental bridges, many of which involved marine-based construction operations in and over navigable waterways.

Our other marine facilities experience includes lock chambers, gate structures, dams, piers and industrial docks, barge loading facilities, and deep-water cofferdams. Additionally, our experience and capabilities also include construction of deep heavy-capacity foundations, including drilled shafts, large-diameter driven steel piling, driven steel piles, micro-piles, and large reinforced concrete spread footings.
