J.C. Cannistraro, the area’s largest mechanical construction firm, will relocate and consolidate its manufacturing and warehousing operations to Boston’s Seaport District.

J.C. Cannistraro, LLC offers complete mechanical construction services within Greater Boston, including plumbing, fire protection, HVAC piping and sheet metal; and facility service and maintenance throughout New England.

According to company officials, Cannistraro signed a 50- year Ground Lease with the City of Boston’s Economic Development and Industrial Corporation for Parcel N, 25 Fid Kennedy Avenue: a 3.5 acre site with a two-story, 157,000 square foot building in the Raymond L. Flynn Marine Industrial Park.

Cannistraro said it will “substantially rehabilitate the property for use as a prefabrication and assembly plant for plumbing, fire protection, HVAC piping and sheet metal systems for installation at construction sites throughout the region.”

Historically known as “Building 16,” 25 Fid Kennedy Avenue was built in 1940 by the U.S. Navy as a multi-trade heavy machine shop. The open, steel frame structure and forty-ton overhead crane capacity facilitated large-scale metal fabrication and assembly supporting the U.S. efforts in WWII.

“The renovations at 25 Fid Kennedy Avenue will preserve the legacy of its industrial Art Deco architecture and utilitarian use,” explains John Cannistraro. “We are proud to showcase the craftsmanship of local tradespeople, and to advocate continuous improvement and best practices within the construction community.”

In addition to providing jobs for Boston residents, the move enables Cannistraro to apply green building technologies, Lean manufacturing principles and modular building methods, company officials said. A significant amount of flex space within the facility will be available for innovative projects in collaboration with industry partners. Cannistraro is expected to occupy 25 Fid Kennedy Avenue in September 2017. The company’s corporate offices will remain in Watertown, Massachusetts.
