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.
