Per this section the common wall shall be constructed without plumbing or mechanical equipment, ducts or vents in the cavity of the common wall.
I have a double wall. 2x4's with 5/8" type x each side, an airspace. Structure requires that a beam penetrate one layer of GWB and sits on multiple 2x4's. The beam is wrapped with 5/8" GWB. The beam is not continuous through to the next townhouse.
The plan reviewer states that the beam penetrates the one-hour separation wall. Either the support posts should be located outside the wall or provide a method of protecting the beam penetration.
Does this sound reasonable? If so, what is an acceptable method of protecting the beam penetration.
And, since the code does not mention that beams or other structure cannot penetrate the one-hour wall, should this even be an issue?
Thanks,
JM
