Defense Intelligence Agency - Bolling Airforce Base
Forrester Contruction Company, Inc. awarded Cynergy Electric the Emergency Generator Replacement project at DIA - Bolling Airforce Base in Washington DC. The work included phased construction to replace four 930KW, 480 volt diesel powered generators with four 2000KW 13.2KV diesel powered generators, and new; day tanks, mufflers, 13.2 KV paralleling switchgear, step down transformer 13.2KV-480 volt feeding a 480 volt emergency switchboard. Also included was the installation of six new 480 volt automatic transfer switches located remotely within the building fed from the emergency switchboard.
The existing generators were designed to provide power only to critical and life safety loads in the DIAC but not the entire building’s loads. The new design is to provide sufficient generator capacity to provide back-up power for the entire DIAC building. To accomplish this we had to provide three new 13.2KV vacuum breaker switchgear cubicles custom fitted to replace existing cubicles in the buildings 13.2KV incoming PEPCO service switchgear.
The nature of the building’s occupants required a high level of security; all work outside the generator and switchgear rooms required a high level escort. Phased outages were required for the installation of the new 13.2KW switchgear cubicles within the existing incoming PEPCO service switchgear.
Miscellaneous installation items included; fire alarm system, monitoring system, low voltage circuits to the parasitic equipment in support of the generators, pump starters, variable frequency drives, control circuits, fans, etc.
Commissioning and field testing was a large component in the project. Load-bank testing was performed on each generator and the generator system as a whole to demonstrate paralleling capabilities. Third party testing was provided for all medium voltage equipment, generators and cables. Factory field services were provided for the generators, switchgear and automatic transfer switches. A third party commissioning agent provided compliance testing on all systems. Hands on training, classroom training and operation and maintenance manuals were provided for all operational systems.
