We're running a sprinkler line from one building to another. I know it doesn't make sense but it's fed from a well , water tank, and pump room. Don't ask unless you want a long, boring, and odd explanation.
We can't bury the sprinkler line so it needs to be in a horizontal chase that is accessible (not ADA, just by maintenance staff). My understanding is that this is considered a shaft per section 713 of the IBC 2021.
Do you think my understanding of this correct? Is this a shaft?
For those of you keeping up with things, yes this is THAT fire station project in a small mountain town. :s
Chad, I'm dealing with a similar situation, but in reverse. Demo'in an old service tunnel from the late 70s.
In my world, such spaces are considered service spaces, not shafts. This triggers a few clauses such as min distance until you require 2 exits plus FRR and exit signs.
I don't think the IBC has a service spaces classification. I could be incorrect though - any idea if the IBC has a service space classification? - I could not find it.
The closest I could find was the shaft classification. This was due to the space penetrating the floors of each building.
Mechanical Tunnel Between Buildings?
This is a weird one so stay with me.

This is my initial thought too, most likely a 2 hr separation, everything sealed right, etc... vs a shaft.
Thanks for the input!

Is NFPA 520 or Chapter 3104 of IFC of any help? Perhaps thinking of this as a vault of utility tunnel?
Thanks! Good idea!
