Systems and methods of using a fire spread forecast and BIM to guide occupants using smart signs are provided. Some methods can include receiving a first signal indicative of a first location of a fire event in a monitored region, using the first location and BIM information to project an area into which the fire event will spread in the monitored region, and identifying at least one smart sign in the monitored region to enable for guiding an occupant in the monitored region to an exit door in the monitored region while avoiding the first location and the area.
