Section 1005.2 (2006 IBC)

[globe trekker]

Continued greetings to all!

Regarding Section 1005.2 in the 2006 IBC, I am having difficulty interpreting this code

section.

QUESTION # 1: Are there two different requirements involved in this section?

If so, which is the more restrictive? I have a design that involves a door opening in to

an (egress) Corridor. This particular Corridor is required to have only 36" clear width

(RE: 1017.2, No. 2). During the opening, the door does not reduce the required Corridor

width to less than 1/2, however, when the door is fully open, it does encroach more than

7" in to the required 36" width.

Thanks for your input!

how wide is the corridor as constructed?

2 requirements distinct from each other....both apply....

I agree - both apply. What is causing the door to encroach more than 7"?

mtlogcabin,

4' - 7" as shown on the plans.

Lori,

This one door is for an ADA toilet and it opens outward in to the egress Corridor.

The problem is that this door, when full opened, impedes the egress path out

of the Break Room which is located right next to this ADA toilet, by more than

the 7 inches. When I scaled it on the plans, it appears to be impeding in to

the required width by approx. 14" - 15".

Thank you all for you input! Your input greatly clarified what I initially believed.

My understanding of the term "fully open" is when the door is swung open until it comes to stop at a wall the maximim permited by the enclosure. Is that what you are describing?

mtlogcabin,

When this one door is fully opened, (i.e. - 90 degrees from the door frame),

it impedes the egress pathway by 14"-15". Does this help?

[mtlogcabin]

Got it. Good catch. Can they relocate the breakroom egress over 7 or 8 inches?

 

[globe trekker]

Can they relocate the breakroom egress over 7 or 8 inches?

Unfortunately, they cannot! The spaces & tolerances are already very tight!

But they could have had the door swing inward in to the maneuvering

clearance for the ADA toilet!

I have already had a telephone conversation with a junior arch. associate,

(AIA certified mind you) and I could tell that he was not familiar with any

Accessibility or egress requirements.

The RDP on this project is a well know arch. firm in the area, but they

have sure dropped the ball on this one. The project is a medical office,

with Exam Rooms & full service X-Ray. Their initial submittal was

substantially less than usual!

I am not slamming any or all RDP's, but it seems to be more about "what

they can get away with" than compliance to the adopted codes & standards.

(i.e. - trying to save their clients money).

How about a self-closer?

 

[elowpop]

Fully open is until it meets the wall. If there is no closer it will swing within 7 inches. Of the wall leaving 4 foot plus.

Should comply with the 7" requirement regardless of closer application.

Sounds like one of those 'learning opportunities' that may come with some $$ attached. Those are the ones that usually stick with you...

Continuing with this thread, when this one door is 90 degress (open) from the door

frame, the measurement-by-scale on the plans impedes more than the allowable 7"

in to the required 36" wide corridor. If the door opens more (to the wall) it will

impede the Break Room (egress) door width by more than 1/2.

Thanks to you all for your input!

Not knowing anything else about the context of the rooms or other design issues, one solution would be to move the door back into the room away from the corridor wall; similar to an alcove. Would slightly decrease the area inside the room and require additional width on the latch pull side for ADA clearances, but would allow both doors to coexist without creating problems in the corridor or impeding the break room door width. Door can open to 90 degrees, project less than 7" into the corridor, and not impede the break room door width. Hope that makes sense.
