Emergency Escape and Rescue Openings - Required in All Group R-2 Buildings?

4/23/2020

9 Comments

 
I'm currently working on a large, multi-family apartment building that includes several-hundred dwelling units. The building is four stories tall and each story has multiple exits. The building is divided up by several fire walls for allowable area purposes, so the exits are a combination of exit stairs and horizontal exits.

​In a recent discussion, the AHJ indicated that he thought Emergency Escape and Rescue Openings complying with IBC 1030 were required for each bedroom in the building. On past projects, I have not seen this required in buildings where each story has two or more exits, so I decided to do a deep dive into the code requirements.

Mitigating Dead End Corridors

4/15/2020

​For years, architect clients have asked me for solutions to mitigate a dead end corridor condition. As a quick reference, dead ends are limited to 20 feet, except in Groups B, E, F, I-1, M, R-1, R-2, R-4, S and U with a full NFPA 13 sprinkler system, where the limit is increased to 50 feet (2015 IBC 1020.4).

Open Vs. Enclosed Parking Garages

4/15/2020

28 Comments

 
For architects and engineers designing parking garages, two questions commonly arise when determining whether the garage should be an open or enclosed garage. These questions are:
  • When can a parking garage be considered open?
  • What are the differences in code requirements for an open garage vs. an enclosed garage?
In this post, we’ll provide a concise overview of the requirements related to these frequently asked questions. I use this writeup as a quick reference guide instead of opening up to the code every time. Hopefully it's helpful for you too! All code references are to the 2015 International Building Code (IBC).

A New Venture - Introducing CodeCalls.org

4/9/2020

1 Comment

 
In starting The Building Code Blog a few months ago, one of my main motivations was to answer frequently-asked code questions in a medium that is widely-accessible. Providing clear code direction to a contractor or architect is impactful, but providing code insights to hundreds or thousands of people in the AEC community is even more impactful. In my work on the blog and elsewhere, I hope to provide that further-reaching impact.

To that end, I have partnered with Joe Meyer to launch a new initiative, CodeCalls.org.
