Heavy Civil & Marine Construction: Reshaping Ports and Cities.

CASHMAN Heavy Civil and Marine Construction provides ingenuity in the face of complexity. Having successfully completed some of the most complicated and challenging heavy civil and marine projects in American history — such as the Central Artery project in Boston, MA and the Cross Island Land Reclamation project in Bermuda — CASHMAN has earned a reputation of excellence when it comes to strengthening communities through quality ports, bridges, tunnels, and railways.

Utilizing sound engineering and advancing in the latest technologies, we provide value-added engineering while executing heavy civil and marine construction projects across a broad array of services — ranging from constructing roadways, piers, and wharfs, to providing marine support for gas, oil and utility pipelines, and to renovating and preserving the historical composition of the berth of the world's oldest commissioned naval vessel afloat, the USS Constitution.  

The CASHMAN Companies own and operate an expansive fleet of specialized equipment including dredges, scows, barges, tugs, cranes and other heavy equipment. This combination of capabilities and resources allows us to act as a single-source provider when constructing the vital infrastructures required to keep your ports and cities moving.
