Best Available Refuge Area Assessments

KFC Engineering’s staff has comprehensive experience in the qualitative assessment of existing facilities for the purpose of determining Best Available Refuge Areas** based on procedures outlined in FEMA-361, FEMA-P-431 and FEMA-BARA Checklist.

For each facility studied, KFC:

  • Performs a review of available record drawings
  • Conducts on-site visits to confirm construction
  • Observes the surrounding environment to determine potential sources of wind-borne debris
  • Completes FEMA-BARA Checklist to develop qualitative score
  • Identifies areas of concern not covered by checklist
  • Provides a written assessment of recommended refuge areas
  • Provides plans defining the best areas of refuge in the facility assuming a no-run-time scenario and based on client provided occupant count

**Best Available Refuge Areas are defined in FEMA P-431: Tornado Protection – Selecting Refuge Area in Buildings as follows: ” The term best available refuge areas refers to areas in an existing building that have been deemed by a qualified architect or engineer to likely offer the greatest safety for building occupants during a tornado.  It is important to note that, because these areas were not specifically designed as tornado safe rooms, their occupants may be injured or killed during a tornado.  However, people in the best available refuge areas are less likely to be injured or killed than people in other areas of a building.”
