wood framed elevator shaft

[structuralnerd]

I am designing a two story church where the design/build contractor is requesting to frame the elevator shaft out of wood to save cost. The architect thinks they can make it work per fire code. Does anyone see issues with this structurally as long as you design the wood posts at the rails appropriately? Typically, I have framed elevator shafts out of CMU or concrete. Thanks.

Other than dealing with and detailing firewall penetrations of the structural members, nothing comes to mind.

Have you checked with the elevator company? They usually attach their frame to rigid concrete, masonry or steel. Attaching to wood, with the vibration and movement of the elevator could create connection problems.

Wood framing is commonly used in my locale for elevator shafts in three story walk-up apartment buildings. There does not appear to be any problem.

Some years ago, the authorities here discouraged the use of CMU for elevator shafts because of the difficulty of attaching rails through the face shell of masonry.

I have done this before.

Pay careful attention to the connections.

We have done it, but had to install steel 'columns' and plates for attachment of the rails and counterweight tracks.
