Thank you for your responses I believe you settled our debate although now
they are asking me "... where are they getting you have to stay within one
standard?" (13 or 13R).
Thanks again.

Subject: RE: 13R Classification
There is a proposal in the current ROP (13R-58, Log #37 - Committee
Action: Accept) that will hopefully give better direction with regard to
this (these) issue(s). Capsule version of the material is to clarify
that if a building (such as a pedestal or podium type) is divided into
separate buildings as defined by the code, that 13R is applicable in the
R-group building and 13 would apply to the other. This represents a
change from what we've been saying (myself, AFSA, here in this thread)
WRT to "mixed use" buildings requiring a 13 design unconditionally.
But the proposed language makes very clear that these provisions apply
to buildings that are no more than 4 stories above "grade plane" (also
as defined by the code), so if we're talking about a 5-story structure
(per code), the applicable standard is 13. Period.

Subject: RE: 13R Classification
Could you consider this 2 separate areas if the building falls under the
"pedestal" design of section 508 (2003 IBC)? I have an excerpt from the
2006 Building Safety Journal that may help.
"In addition to the basic requirement that the pedestal
building be of Type IA construction and separated from the
buildings above by a horizontal ceiling/floor/roof assembly
having a minimum 3-hour fire resistance rating, the following
limitations also apply.
* Per Section 508.2, Item 4, Exceptions, the use of the
pedestal building is restricted to any combination of the
following:
* S-2 enclosed parking garage;
* multiple Group A uses limited to those having assembly
rooms with occupant loads of less than 300 each;
* Group B uses;
* Group M uses; and
* entry lobbies, mechanical rooms, storage areas and
similar uses incidental to the operation of the building.
* Per Section 508.2, Item 3, the use of the buildings above
the pedestal building is restricted to any combination of
the following:
* Group R uses,
* multiple Group A uses limited to those having assembly
rooms with occupant loads of less than 300 each,
* Group B uses and
* Group M uses. "
Hope this helps. Bobby, leave me email if you want the full article.

Plus, it's mixed use. 13 throughout.
One building, one use, one standard, one design.

Hello Bobby,
I was taught if there is a 5th floor it is not 13R. The whole building
has to be 13.
