NCARB Graphic Vignette direction stated:
“Non-bearing corridor and Lobby walls must have a one-hour (minimum) fire-resistive rating.”
On the attach image [Image Deleted]I highlighted all the walls that surrounded the lobby and corridor area. I want to make sure that these walls (please correct me if I am wrong) must have the one-hour (minimum) fire-resistive rating?
Please Explain. This is the portion where I panic and failed. Please.
