Landing at top of ramp

[jar546]

When is it possible to have a ramp where the landing is inside a vestibule? In other words, at the top of the ramp there is an automatic door. I can only see this as possible with a automatic sliding door. How do you view this for a landing?

What happens during a power failure?

ANSI 117.1 Section 405.7. Take a look at it. I don't see any way not to have a landing at the top of a ramp.

No exceptions for an automatic door.

I'd say no because of the possibility of a door malfunction.

I don't think that works.

Jeff,

They're all right. No can do.

The landing needs to exist in front of the doors and at the top of the ramp. You can't have the landing on the inside, beyond the doors. Even without a power failure, what about the person who arrives at opening time and has to wait for the clerk to activate the automatic doors?

I agree with the others and I'll add that I don't see how you could comply with IBC (2009) 1008.1.5 without the landing.

Whenever the ramp and bottom landing are also within the vestibule, or whenever the vestibule is unenclosed.

Yes, unenclosed without a door. Thank you.

I see no other way around this particular situation except for adding a landing at the top of the ramp.

I though they called an unenclosed vestibule an "alcove." :lol:

A landing is required at the top and bottom of all ramps. Section 1010.6

A landing or floor is required on each side of a door. Section 1008.1.4. Such floor or landing shall be at the same elevation on each side of the door.
