Weeks Marine

A proven leader in maritime construction, Weeks has successfully completed projects throughout North and South America, from inland waterways to off-shore sites in the Pacific and the Atlantic.

Weeks Marine has three key divisions—Construction, Dredging and Marine Services—which are bolstered by two major subsidiaries, Healy Tibbitts Builders, Inc. and McNally International, Inc. Their vast reach and deep expertise, combined with the sheer size and diversity of the equipment fleet, enable them to serve as a one-stop shop for clients in both the private and governmental sectors.

Established as a family-owned company in 1919, Weeks Marine strengthened our operations when it acquired us in 2011. In 2023, the Weeks organization was acquired by Kiewit Corporation to become wholly-owned subsidiaries of Kiewit.
