2018 IBC Required Ramp Width (1012.5.3, 1014.8)

walker.t said:
My original question was more than just asking about the minimum width, I was trying to reconcile how 1012.5.3 says projections are not allowed into the required ramp width when other provisions say that projections are allowed. 1012.5.1 makes reference to “other permissible projections,” any idea why this provision allows for projections when 1012.5.3 says “projections into the the required ramp and landing width are prohibited”?

A camel is a horse by committee. The IBC has many committees. It's that simple. I joined my fist code committee in 1987 and sometimes I look at code text today and say wonder how the heck we all signed off on it.

Oh I was just poking fun at steveray. He can't answer that question... Oh he'll try. It's now 46 replies into this and nobody has answered that question.

Well let me try then...

My bad, it was my intention to direct my response to steveray, I forgot to quote him, I’ll try to remember to include quotes in future posts.

I would say that is trying to say that projections are allowed over the ramp, but not to the point where they impinge on the minimum width per 1012.5.3...

Soooo.....If you were required to have 3' and you installed 4' wide you theoretically could have HR that stick in 6" on either side...Barring any other weird projection limitations....

How did I do?

Actually, I think your comments here are leading us to the finish line.

That’s a good example clarifying 1012.5.3, but 1014.8 says projections into the required width are allowed. But 1014.8 makes reference to ramps that are part of an accessible route, not specifically ramps that are part of the means of egress. So if a ramp is part of an accessible means of egress, 1012.5.3 nullifies the allowance in 1014.8 for projections into the required width.

I think the key to my initial confusion was reading something into 1014.8 that wasn’t there - it does not specifically reference means of egress ramps.

Code 101:

[A] 102.1 General​


Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable. Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern.

The ramp section is SPECIFIC to ramps.....
