Building owners, designers and contractors today are increasingly using building information modeling (BIM) as part of the mechanical design and construction delivery system. P.J. Kennedy & Sons performs Building Information Modeling utilizing AutoCAD® and Revit® modeling software in conjunction with NAVISWORKS® to ensure that project design and timing is coordinated between the various trade groups. Once completed, project teams utilize the model to extract installation shop drawings and fabrication drawings for multiple field applications. This prefabrication aids in moving labor to off-site fabrication facilities, further reducing field installation time and improving the overall project schedule.

Founded in 1925, P.J. Kennedy & Sons is a 3rd generation business. Our core principal has always been to treat our employees and our customers like they're one of our family. We pride ourselves on building real relationships, and have a well earned reputation for integrity, quality and performance.

With a pre-fabrication facility and 24-hour service team for emergencies, we’re equipped to take on all of our client’s mechanical needs at every stage.

With decades of experience and the latest industry technology, P.J. Kennedy & Sons is dedicated to the success of every project. We’re masters at collaborating with other trades to get jobs done on time and on budget.

"I have had the pleasure to use the mechanical services of P.J. Kennedy & Sons for over fifteen years and no matter how difficult the job is the management and staff always have the “can do” attitude when meeting any challenge. At the Prudential Center located in the Back Bay of Boston they recently completed another challenging job which involved the replacement a 900lb. chilled water coil and as usual their team took care of the project in a safe and efficient manner.

"Our most recent project, the UMass - U. Hall, was by far our most difficult, the most involved and the most interesting project that we have done together to date.  P.J. Kennedy & Sons performed both the HVAC and Plumbing on the project. The building contains places of assembly such as a 500-person auditorium, a recital hall, a black box theater and a full height atrium.  It also has a full floor of science rooms with 100 fume-hoods, the upper floor contains a dance studio, acting studio and various art rooms. Topping it off is a full floor mechanical room that houses the multitude of mechanical systems to service all of the different requirements of the spaces below.  P.J. Kennedy & Sons orchestrated a very impressive fit-out of that room through one glory hole in the side of the building. The coordination, installation, start-up and commissioning was completed without a hitch."
