J.F. Brennan Company, Inc.

At Brennan, we specialize in dam construction and repairs on navigational, hydroelectric, diversion, storage, detention, and earthen structures of all sizes.  We work on every part of the dam, both above and below the waterline.  Brennan crews have the experience and equipment necessary to work in a variety of conditions, including confined spaces, elevated work stations, underwater construction, and more.  When most firms pursue dam work as a secondary focus, we have made it a primary focus with dedicated crews, specialized equipment, and a robust safety program.
