Maintain egress path - the construction area is to provide a clear exit path to the exit door from the neighboring occupied phase in the case of a fire alarm. The door in the rated construction wall separating the occupied space and the construction phase is to be secured electronically and tied to the security/ alarm system and is to fail safe (unlocked) in the case of alarm or power failure. This door can be re-used from phase to phase in the construction walls.
