Hello,

I am doing a remodel/rehab of a 1917 building.

Details:

3 story plus basement.

12,500 total sf

Original construction: steel frame exterior masonry bearing wall. All brick exterior.Original Clay tile fire protection at steel.

We are updating to 2012 IBC and major code updates include, ADA conformance & adding sprinklers as per NFPA 13 throughout.

The entry door to the building is now part of a fire egress stairway, separated from the rest of the spaces in a lobby/vestibule.

The door faces another building on campus at 18' from face of building to face of adjacent structure.

The exterior walls are considered 1-hour exterior bearing walls in VA construction, and the door in question falls between 10 and 30 feet which requires the frame/door to be rated to as per table 602.

Q: If the corner of our building to adjacent building is 18' - but the exterior egress door faces an open space, do I need to rate this exterior door and frame?

Am I reading this correctly?

Thanks!

Scott
 
The fire separation distance is usually measured perpendicular to the building.....if they are both on the same lot, an imaginary lot line needs to plotted and you can take measurements to that....
 
Steveray,Got that part - thanks.Building #1 is 100' long and only 20' of the bldg footprint is within 18' of bldg #2. My question is does only the 20' portion of the bldg #1 apply or does the whole 100' need to be rated (which would include the egress/entry door) as per table 602 and table 716.5
