    Hello, I'm coming to you all for a reality check on my interpretation. What I'm dealing with is a historic wood floor on sleepers with open air gaps between the sleepers.

    2018 IEBC Minimum Ceiling Height in Historic Building

    2018 IMC Definition of Corridor?

    "Corridors shall not serve as supply, return, exhaust, relief or ventilation air ducts." So if I'm not required to have a "corridor" and my condition is partial height non-rated walls bounding a path that people do use as exit access with no ceiling.... Can I return air through the space?

    2018 IMC Definition of Corridor?

    The 2018 IBC defines a corridor as: An enclosed exit access component that defines and provides a path of egress travel. IMC does not contain a definition. My project is not required to have rated corridors. However, IMC 601.2 says - Corridors shall not serve as supply, return, exhaust...

    IBC for Plumbing Fixture Count / NFPA 101 for Egress Occupant Loads

    Hello, I am working on a project in an area that has adopted NFPA 101 for Life Safety/Egress but for Plumbing the code is the 2018 IPC, which says to follow IBC for occupant loads. Normally, I would find my IBC occupant load and use it for both. Now it seems I have to go through this effort...

    1991 Uniform Building Code Occupancy Classification

    It was checked for ADA compliance and the results were very good with the exception of a few ramps we want to demolish anyway. The state this project is in adopted the 2012 IBC with modifications. No adoption of the IEBC, which I believe changes to be adopted by reference in the 2015 IBC. So...

    Labeled Definition and NFRC Labels - 2018 IECC

    I should have stated that the project is going the performance route not the prescriptive route. The default values in the tables will not work for passing the performance route. I think my question is whether there is a "nationally recognized testing laboratory, approved agency or other...
