Massachusetts General Hospital, Emergency Power System Upgrade
DCBA performed preconstruction and construction to the emergency power system at MGH’s downtown Boston high-rise hospital building. Preconstruction activities included comprehensive value engineering to make sure that the plan was cost effective, quality-conscious, and met MGH’s expectations. Construction involved installing a new fuel line riser from the garage to the penthouse and a new 1500kw emergency generator system on the roof of the building as well as integrating emergency power with each floor. Work such as welding, coring, and hoisting needed to take place off hours to avoid disrupting the clinical space within the active hospital. Hoisting the new generator was a challenging undertaking, one that required DCBA to coordinate activities with the building facilities, neighboring buildings, and subcontractors. Prior to starting the construction portion of the project, DCBA established many safety checks and systems. Egress routes were used to ensure the safety of pedestrians and drivers. Workers installed temporary stairs in order to easily and safely move from one level of the roof to another until permanent aluminum stairs were installed. An orange fence perimeter was also utilized to clearly mark the edges of the roof. Tie-in of the existing emergency power systems to this new generator brought the system up to code and was done in such a way as to allow the building to remain functional.
