Hi Bill,
Hmmm, wait until after the fire ?, not me. Here are the EXACT definitions and stipulations from the 2015 IBC that apply; 702 FIRE WALL. A fire-resistance-rated wall having protected openings, which restricts the spread of fire and extends continuously from the foundation to or through the roof, with sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall. 706.1.1 Party walls. Any wall located on a lot line between adjacent buildings, which is used or adapted for joint service between the two buildings, shall be constructed as a fire wall in accordance with Section706. Party walls shall be constructed without openings and shall create separate buildings. 706.3 Materials. Fire walls shall be of any approved noncombustible materials. Exception: Buildings of Type V construction. 714.1 Scope. The provisions of this section shall govern the materials and methods of construction used to protect through penetrations and membrane penetrations of horizontal assemblies and fire-resistance-rated wall assemblies. 714.3 Fire-resistance-rated walls. Penetrations into or through fire walls, fire barriers, smoke barrier walls and fire partitions shall comply with Sections714.3.1 through 714.3.3. 714.3.1 Through penetrations. Through penetrations of fire-resistance-rated walls shall comply with Section714.3.1.1or 714.3.1.2. 714.3.1.1 Fire-resistance-rated assemblies. Penetrations shall be installed as tested in an approved fire-resistance-rated assembly. 714.3.1.2 Through-penetration firestop system. Through penetrations shall be protected by an approved penetration firestop system installed as tested in accordance with ASTM E 814 or UL 1479, with a minimum positive pressure differential of 0.01 inch (2.49 Pa) of water and shall have an F rating of not less than the required fire-resistance rating of the wall penetrated. So, a designer will need to demonstrate a tested/listed system for the penetrating items for the specific application. Another issue to consider with Party Walls, since a party wall sits on a lot line and thus in addition to creating separate buildings also creates separate lots. With that said individual property ownership issues could necessitate an easement, so ownership issues may need to be considered. Bill to answer your question it's the Missouri thing..show me, not just that's it permitted by code but how.

I have seen the interpretation which appears to suggest that a sprinkler pipe penetration of a fire wall would not be acceptable if the pipe (in coming down with collapsing side) somehow compromised the gypsumboard separation assembly. Same with an electrical conduit. I'm also not sure how to design the collapsing side in such a way that it falls cleanly to the ground without some member shifting sideways and penetrating the separating assembly. In other words, do you wait till after the fire to say it works or doesn't work?

Two floors, even if within the area limits of a single system seem to define two zones. Just thinking, and remember that Leyton was concerned this morning that my meds have lost their efficacy, so I may just be having another flashback to the sixties.
