Demolition of the NRTF Antenna Towers

The Navy shore VLF/LF transmitter facilities transmitted a 50-baud submarine command and control broadcast that was the backbone of the submarine broadcast system, during World War II. As a function of the realignment the transmitter facilities were abandoned and scheduled for removal. As part of the Base Realignment and Closure (BRAC), the Navy Radio Transmitter Facility (NRTF) in Annapolis was planned for closure.

Brudis & Associates, Inc. successfully developed a complete design/build program, which involved a quality based selection of the contractor, for the felling, demolition and removal of 19 antenna towers ranging from 1,200 feet to 80 feet in height. Several of the towers were structurally tied together and needed to be felled simultaneously, while other need to be removed in sections to avoid site damage.

BAI also developed site restoration specifications and cost estimates, for the existing impacted utilities, seawall and the Chesapeake Bay Causeway and provided design specifications/details for the base’s golf course reconstruction at two of the felled towers areas. In addition, since native osprey was using the antenna towers, BAI designed osprey-nesting platforms for the Seahawks.

The design was then site adapted to specific locations by BAI and successfully constructed at the Merkle State Park in Prince George’s County, and the Fair Hill State Park in Cecil County.
