This may or may not help you . . . Section 307.3 of the ADA Standards addresses “Post-Mounted Objects”. Standpipes probably aren’t technically ‘posts’, but if the standpipe extends down to (or through) the floor, the concept is the same. That section allows objects attached to the posts to extend up to 12” from the post. If you don’t come up with a better defense, it may be worth pursuing.

And unless we’re the only ones not privy to some kind of “micro hose valve” I’m pretty sure every standpipe installation in existence would have this same issue. Which is why I’m thinking there must be something I’m missing. -Kyle M From: Nick Maneen [mailto:[email protected]] Sent: Friday, November 22, 2019 12:36 PM To: Kyle.Montgomery <[email protected] <mailto:[email protected]> > Cc: [email protected] <mailto:[email protected]> Subject: Re: [EXTERNAL] Re: Cane Detection Sorry for the incomplete email. It just went ahead and sent... Anyway, in my experience, a piece of pipe on a floor flange under the standpipe should work. It seems to follow the illustration David Blackwell sent.

One of my issues right now is that the GC is siding with the AHJ and just saying “Yep, we need it, you need to provide it, no extra money.” The problem we have is that the hose valves protrude more than 4” from the standpipe, so we’re being told it is required. But I’m pretty sure every hose valve on every standpipe in existence does this, so how has this never been an issue for us before? -Kyle M From: Nick Maneen [mailto:[email protected] <mailto:[email protected]> ] Sent: Friday, November 22, 2019 12:19 PM To: [email protected] <mailto:[email protected]> Cc: Kyle.Montgomery <[email protected] <mailto:[email protected]> > Subject: [EXTERNAL] Re: Cane Detection I have been asked to turn the valves so they don't protrude further from the wall than the standpipe does (leaving clearance for firefighter use) and run the standpipe down to the floor so the cane can find the bottom of the pipe. I have had an AHJ accept a piece of 1" that does from the bottom of the standpipe to the cap on the 4" to act as the detection. I don't think bollards would be required or at least they haven't been around here in North Carolina yet.

For those of you who may not be familiar with the term, the short answer is that cane detection is required for objects that protrude into the circulation path so that a blind/visually impaired person can detect the presence of the object with his/her cane and therefore not bump into it. It’s required for objects that protrude more than 4” from the wall, and are located within a height range of 27”-80”; objects higher than 80” are above the required headroom clearance, and objects lower than 27” are within the “cane sweep” and thus will be detected. (Just Google “Cane Detection” for more information) I understand the need for this, but am uncertain of all the requirements. Here’s our situation: We don’t need the detection for the standpipe itself (or the drain) because that continues through the floor and can be detected by the cane. However, the hose valves protrude more than 4” from the standpipe, and are above 27”, so we’re being told that we need it for the hose valves. So, I’ve got two questions: 1. Is the code being applied the correct way? Have any of you run into this and are the any exceptions for standpipes or life safety equipment? I’m wondering how this hasn’t been a problem for us many times before if this is the correct interpretation of the code. 2. If this IS the correct requirement, should the installation of cane detection fall to the fire sprinkler subcontractor? I mean, we’re not typically responsible for installing bollards to protect risers in warehouses and similar. I’m interested to hear the forum’s thoughts and experiences. Thanks for your help.
