Chris: Can show you "non-required" stairs on numerous projects. Currently doing a library resource center for a community college. Three stories with a giant open atrium - open to all three floors - right in the center. Grand open staircase in the center of the building - in the language of the code, a "convenience stair". The three required exits are all conventional shafts and scattered around the building. I can show you plenty more where that one came from ...

Even the IFC uses similar language. If it ain't required you don't need a standpipe. As a FF I of course think that would be bad design as I would have no idea when the building is on fire which stairs are required and which aren't. Thus I wouldn't know where to find standpipes. As an FPE I agree with myself the FF. Further I'd walk from a job (in a normal economy) where the standpipes weren't in every stair leading to an egress. In this economy I'd certainly write lotsa CYA letters for the only job we would have. (Sorry I do need to eat). As a former AHJ I'd fight for every stair until the judge overruled. My only case lost as AHJ was over an exterior standpipe for a Cathedral copper reroofing job where the Chief wanted a standpipe to reach the top (over 250' above grade no access from the inside). Tactically the Chief was right but the City Council sided with God's representative. Once that happened the City couldn't proceed to a judge. I assume I'm going to Hell anyway so arguing against God really didn't chance anything. Now I can't think of a place where a stair was there but not required, but it is certainly theoretically possible. (Assuming something can be "certainly theoretical") Closest comes to mind is a convenience stair connecting several floors. Some might go to street some might not. In a legal contest the required part is going to be key if all the experts like the architect show up and have all the exiting calc's done showing the stair in question is not required. My money is on the NFPA committee believes all stairs get standpipes but that is not what they wrote - Steve..... In a legal deposition (or worse on cross in front of the judge) on the side of the standpipe how are you going to answer the questions along the line of Mr. Huggins have you reviewed the Architects exiting analysis? Assuming you had the follow up is - Mr. Huggins is there anything wrong with the analysis as it applies to the minimum requirements of the Code? Assuming there wasn't - Mr. Huggins does the analysis show the stair in question is required? And you wouldn't have gotten this far if it was required - Does the IFC and NFPA 14 refer to standpipes in required stairs? You really are in a corner to say yes - And finally Mr. Huggins what does the LAW say about non-required stairs? I'd guess you'd respond "nothing, but...." And your counsel will have no choice but to drop the matter. I try to use my powers for good so let's change the IFC and NFPA 14 to change this loop hole. Might be as simple as dropping the word required. Now I don't know if Greg's stairs are required or not. I tend to think they are required so really the discussion is mute but it does reveal a flaw in the code that until now I had not thought of. Chris Cahill, P.E.

If it is an actual stairway exit, it is considered required.
