An experienced dredge team analyzes all the project parameters to determine the optimum equipment for completing the work. This involves knowledge of how sediment characteristics impact equipment selection and material handling, including stabilization and final placement. Whenever possible, the company looks for opportunities for beneficial use of dredged material, which often can be a valuable asset as construction fill or for beach re-nourishment.

Company History

JT Cleary was founded in 1995 to provide marine consulting services in the New York City metro area. The company quickly moved from consulting to contracting and developed into a leader in marine construction, deep foundations, and diving. Operations subsequently grew throughout the Mid-Atlantic and Northeast regions.

In 2005, JT Cleary expanded again, offering dredging services, including maintenance, navigation, and environmental dredging. The company has completed dredging projects for USACE, USCG, NAVFAC and numerous private clients.

In 2018, JT Cleary was acquired by the Tully Group, also based in New York City.  Tully Construction, the largest privately owned construction company in NYC and one of the largest in the US, has capabilities in the heavy civil, transportation and environmental sectors, and has completed many landmark projects in its over 80 years in business.

JT Cleary’s focus on quality reflects the expertise of the staff and a corporate culture of innovation and collaboration. Through this approach, we work with clients to implement their vision in the execution of marine infrastructure projects.
