ADA CODE QUESTION

I've working on a project and we are trying to integrate a Stramp into the project a'la OMA (see photo) 

However per the ADA handrails must be provided on both side of the ramp. I'm not sure how they were able to do this. Is there a provision which allows exceptions if alternate routes are provided. I've also attaching a snip of the pectinate ADA codes Thnx for any help.

Clue: is that a ramp?

yeah, there is likely a real ramp, c/w compliant handrails as well as a lift just out of the picture frame.

I looked at the plans there isn't one I don't think this is actually coded compliant, not sure how they got away with this. Maybe it was a provision in an older code.

It's probably listed as seating and not stair/ramp. It this was a stair case, would it not need centre handrails spaced 2m O.C... or something like that?

Clue: how steep is a ramp?

ADA requires 1:12 this looks to be about that. 1:20 does not require a rail.

s=r*(theta)

let me take a moment from all the current fires that are burning and direct my attention to yours....

brilliant.

Well thank you for taking time away from fighting fires to post on my thread......???

s=r*(theta)

^No prob. I was thinking 50% shoot form the hip 50% social media/ entertainment aspect

Haha all good I don't know if this really has a good answer

maybe it's not part of an accessible route? and there is another ramp hiding somewhere out of the picture?

no, there isn't; and that ramp doesn't comply with ada. Code enforcement oversight? or starchitect exemption syndrome?

It was 2003 and maybe one of the first stramps, either the code has changed or they got a pass

certainly a ramp, but its not an ADA ramp. could be a skateboard ramp for all i know

Its NOT a ramp! Walking surfaces can have a slope of 1:20.

Could be, hard to tell from the picture

"ramp seating, a terrain for student gathering that combines vertical circulation and a handicapped ramp in one form"

I dunno, looks like it's slopes 3 steps.  Say each rise is 7"...that's a 21" transition.  The run of the ramp doesn't look long enough for a 1:20.

It’s two steps bro- and what if they are 6” steps?

The second ramp from the bottom is 3

JeromeS

Second ramp from the bottom clearly has a longer run.

As this whole "not a ramp" argument is contingent on the "sloping floor" having a slope of not more than 1:20 ... you'd think that one of you would be able to reach out to one of the 33 archinect members that are also listed as current students at IIT and convince them to take a tape measure and clear it up for everyone.

yup- sloped surface vs ramp fixes the ramp handrail issue, and looking at the photo, it looks like the stairs are ok, with all the required egress capacity within 30" of the handrail, no intermediate handrail would be required. The landings on the sides of the stair would certainly be deep enough...It must have been a joy explaining how that sloped surface doesn't require a guardrail because of no 30" side drop occurs within 36"of the sloped surface, and also how no one will ever try to use it as a stair, where the 4" min riser height is violated...

Then why they call it handicappex

JLC-1

Can't edit on the phone, why they call it handicapped ramp? See

do we really need to put people at the risk of breaking bones just to stroke some architect's ego. (yes)
