Fire Protection for Mezzanines

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.

Welcome Dekker,

 

That is quite a push you propose:

 

1. Exiting?

2. Access (wheelchair, stairs)

3. Fireproofing

4. Structural load

 

We did a similar "add a mezzaine within a high story space" at the old ABC Entertainment Center in Century City back in 71', but not on the 52nd floor. Exiting and fire were major issues we resolved.

Hello Michael Mankin,

What document are you quoting from?

 

"Don't forget the wheelchail lift, if in California:

"Floors within a given story shall be connected by a ramp, elevator, or lift.""

In a building that high even if the code doesn't require fire proofing wouldn't it be safe to include this protection?
