Manufactured wood stairs in commercial.
(OP)
I have a 4' wide staircase to a basement in a building to be built with hollowcore planks for first floor. Original plan called for precast stairs, but owner now wants to build in wood. Local stair manufacturer says they have a commercial grade stair, but doesn't provide certification or calcs to back it up. From my internet searches, seems to be a common situation. The max span in my case is about 9' horizontal.
Anyone ever seen calcs for a straight, pre-built wood staircase? for 100psf? I don't want to reinvent the wheel if i don't have to.

Are you sure? We have designed 3 and 4 story timber framed condos. IBC didn't require non-combustible stairs.

The architect doesn't want me to whip out my calc pad and design and detail new stairs, just to spec a wood staircase. I was investigating the likelyhood of actually getting a staircase that can be provided as spec'd, like steel.
Looks like that's not likely. Thanks.
