Freestanding Elevator Hoistway Fire Rating

[bryan@gradeconstruction]

We are having a hard time finding clarification on what is required, if any, if the exterior walls of a pre-fabricated free standing elevator, in an open air, would require a fire-rating?

The Elevator will be in the open, attached to an open-air platform, not attached to a building or parking garage, or any other enclosed structured.

Three of the walls will have a stucco exterior and the remaining side will have a glass façade with aluminum store front framing for its entire height.

Is there any fire rating needed for the glass façade? The interior Hostway structure is structural steel tubing, as you can see in the below picture.

The total travel height of each elevator is 30 feet from grade, which has a total of 2 stops level.

I cant seem to attach images here, I can email the prints and specifications



Any information you can provide or guide us would be much appreciated!

If the elevator hoistway is not located within a building, then all walls of the hoistway enclosure are treated as exterior walls. Exterior walls only need to be fire-resistance rated if required by construction type and/or fire separation distance from adjacent lot lines per IBC Tables 601 and 602.

What type of construction do elevators fall under? I'm having a hard time depicting it

I would go with Type IIB, call it a Group U occupancy for this particular application. At that point, no fire rating is required, assuming no other structures are within 10'. Type IIB is non-combustible construction that does not require any fire separations. Group U is a miscellaneous structure, which I think is appropriate for this application.

If anyone disagrees, I would love to hear your reasoning.

What is the purpose of this elevator? Just to see the view?
