MEP Design for SCIF Spaces

Designing MEP systems for sensitive compartmented information facility (SCIF) environments requires attention to detail and a thorough understanding of what it takes to meet Intelligence Community Directive (ICD) 705 standards. Whether it’s a new facility or an interior fit-out of an existing space, GHT works to secure the perimeter and ensure systems meet ICD 705 requirements for HVAC and power.

 

Level 1: Physical Security Isolation Only

This type of project involves slab-to-slab mesh and man bars for ductwork over 96 square inches to prevent access. Bulletproof walls can also be incorporated to further secure the space. All receptacles and tele/data outlets on the perimeter walls are surface mounted within the SCIF to avoid penetration into the SCIF boundary.

 

Level 2: Physical and Electronic Security Isolation

Building off the physical security measures in Level 1, Level 2 incorporates security measures for any ductwork, piping, or conduit passing through the SCIF perimeter walls. Every duct, HVAC pipe, and sprinkler pipe must include a non-metallic break to prevent electronic surveillance. This type of project also requires radio frequency (RF) film in the walls to prevent electronic signals from exiting the SCIF space. Fire alarm audible devices are typically bells or horns within the SCIF space, however, if voice evacuation speakers are required, additional systems, such as self-powered amplifiers are implemented to prevent electronic surveillance.

 

Level 3: TEMPEST Level Isolation

In addition to the physical and electronic security measures in Levels 1 and 2, the TEMPEST level requires complete isolation of the SCIF space from the rest of the building’s systems. This level involves a dedicated HVAC system serving the SCIF only, as well as separate power panels and transformers, if required, with power filtering. This minimizes the number of penetrations into the SCIF space by MEP systems.
