Jeanie,

               Attached is the modified sketch showing both conditions – with wood blocking above/below the cabinet and with GWB applied above/below the cabinet. Some installations may combine both. It is my understanding that an on-site inspection resulted in approval of some completed work and the contractors are proceeding with work in this manner. Dave would be able to provide photos if there are further questions. Thank you for your swift responses to this issue.

Hi George,

A GWB surround is acceptable, how will this be fastened? All penetrations into the cabinet shall be fire caulked as well. 

Can you please provide a cut sheet on the heating unit? 

Thanks,

Jeanie

Jeanie,

               The contractor has proposed a modification to the original sketch which would substitute GWB at the top and bottom of the heater enclosure in place of the 2x6 blocking at those locations. The 2x6 studs at the cabinet sides will still be used. I’ve attached a modified sketch. Would this also be acceptable?

Ben,

Thanks for also clarifying the framing detail around the heating panels as shown in the photos as boxed in with 2x6 in the staggered stud wall. This detail appears to satisfy the IBC requirements  for protection of penetrations in a rated wall.

You have my approval to proceed with this work. I'm not sure of the extent of the close in inspection approval from Don, as you know he is out. Please have the contractor schedule an inspection for a look at this detail around a sampling of panels prior to covering.

Jeanie

Tom,
Please see the attached WCPR #9 for Oak Street Lofts. This direction addresses a fire-rated wall condition noticed by City inspections.
