John, now that you bring up the subject of collapse on both sides, just how do you treat this subject? 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?

You just can't make this stuff up.

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.
