Vertical penetrations are considered openings between floors. What about chase walls between restrooms? It seems as though some consider this a vertical penetration. However, these plumbing chase walls usually do not penetrate the floor like a shaft does.
My question: Are plumbing chase walls considered true vertical penetrations by BOMA?
Thx
Michael
Hi Michael,
No. A horizontal plumbing chase is not considered a vertical penetration. However, it is sometimes difficult to determine what portion (if any) of such spaces are penetrating the floor slab without opening up the wall. We usually compare these areas from floor to floor and look for certain patterns on the plans to help us determine this.
