I have an existing 52 story Type 1A Building.
All floor assemblies, the roof, columns and substructures are protected by SFRM.
My 52nd floor is a 30 foot high space, we are proposing an intermediate mezzanine.
Does the mezzanine structure (deck, beams and columns) also require fire proofing.
Technically the mezzanine is not considered a new floor, however it is oocupied space.
