SVA provided mechanical/electrical/plumbing (M/E/P) engineering services for conversion of an existing storage room at the Maryland Emergency Management Agency Headquarters at Camp Fretterd, Maryland for use as a Sensitive Compartmented Information Facility (SCIF). The SCIF was constructed in an existing room serving as a storage/workshop within the MEMA Headquarters building. A building addition was constructed to replace the displaced storage room/workshop. The project was constructed under funding from the U.S. Department of Homeland Security.
HVAC for the secure communications room was provided as a separate zone, with a new VAV terminal unit off of the existing building variable air volume (VAV) HVAC system. Since the entire facility is used as a command post in case of times of emergency, the building HVAC system was reviewed and determined to be appropriate for the emergency communications room. HVAC was arranged to maintain SCIF standards for non-communication of sounds from inside the room to the surrounding spaces. A separate electric panelboard was provided to serve the additional circuits required in the communications room. This panel was connected to the existing building emergency power electrical distribution system.
The new storage room/workshop was constructed as an addition to the existing building and was designed to withstand Category 4 hurricane force winds up to 155 miles per hour. As such, penetrations through the walls or equipment on the roof were minimized. HVAC for the room was provided by a split system direct expansion HVAC unit with condensing unit located at grade immediately outside the building addition. New fluorescent lighting was provided within the addition, with convenience receptacles and plugmold strips provided for the workbench area. New circuits were connected to an existing panelboard within the existing building.
The existing domestic and fire protection water services for the MEMA Headquarters building fall beneath the footprint of the building addition. These services remained operational and the building addition was designed to minimize impact on the existing utilities. Grade beams were designed by the project structural engineer above the pipes to maintain the utilities in service while transferring building loads away from the piping.
Existing toilet room ventilation had been provided through an exterior wall louver at the location of the proposed building addition. This system was extended through the addition to the new exterior wall.
The project design concepts provide a SCIF rated communications room for communications with national leaders during emergency situations, within an existing facility. The design will place minimal impact on building operations or occupants during construction.
