Remove & Replace Generators – Walter Reed Navy Medical Center

Remove and Replace two 450kw generators at Bldg 16 – Walter Reed Navy Medical Center, Bethesda, MD

SDC was tasked with the replacement of two 450kw emergency generators on the mezzanine level of building 16 at Walter Reed National Military Medical Center. The existing two generators were installed in 1976 as a modernization/expansion of the utility plant. These generators provide the emergency backup power for the chiller and boiler plants serving multiple buildings. The newly installed generators have new double wall 100-gallon day tanks fitted underneath of the generator units. The day tanks are connected to an existing fuel system and fill automatically from the existing storage tank on the mezzanine. The location of the generators units provided a significant logistic challenge. The units must be removed through the exterior wall louvers on the third level of the building. To overcome this challenge, SDC is installing rigging platforms to slide the units to the exterior of the building for removal by crane. The replacement units are installed using the same rigging platform.
