Pedestrian Walkway & Free Standing Elevator

[gmcalifornia]

Can someone please provide insight on this fire separation and freestanding elevator / pedestrian walkway question?

California Building Code, new 4 story V-A, S office building adjacent to an existing grain silo that he'd like to convert to office space further down the line. In the mean time he wants to plan for a free standing elevator that is linked to each building with a pedestrian walkway per 3104.

The new elevator will be modular, 2hr exterior rated and will need its own shear bracing system which I assume will be steel.

My questions:
Can a freestanding elevator exit directly to a pedestrian walkway? A 3/4 hr protected opening would be required at the elevator door.
Do you see any issues with a pedestrian walkway crossing two fire separation lines?
Anything else stand out as an issue here?

Welcome

Not into elevators

The elevator is outside???

Not attached to anything besides the walkway??

If so why does it have to be in a rated enclosure?

 

[TheCommish]

will the elevator be on an accessible route from all areas of the buildings?

The rating is due to fire separation distance - the new exterior exit stair will be closer than 10' to the new elevator building therefore requiring fire protection per 1027.5 exception 3.

The modular elevator shaft is designed as a 2 hr rated shaft.

It would be attached to the walkway and / or silo for bracing and considered as part of the grain silo if needed.

will the elevator be on an accessible route from all areas of the buildings?

Yes

All buildings not on same property?

that would be the issue, if on private property vs public sidewalk
