Tall Timber Construction- tests codes and future projects

If you are looking for more information on tall timber construction check out this slide deck (yes another offering from UL/FDNY/IAFF forum back in January) This presentation shows more information about how the tests were conducted, discusses a handful of projects and then building code information. This presentation was delivered by Cleveland’s former Battalion Chief, Sean DeCrane and you are missing a lot just getting a peek, but even this peek offers a lot of valuable information if you are interested in learning more check it out.

 

Thank you to UL for allowing me to share this information.

Questions about tall timber construction?

Questions about CLT?

Here is another presentation from the UL/FDNY/IAFF forum  Meeting the Challenges of the Future Built Environment at the New York City Fire Training Academy Randall’s Island, New York City. This presentation was delivered by Raymond O’Brocki and discussed things such as the ICC Ad Hoc Committee on Tall Wood Buildings, their objectives, the tests and their findings. There is some great information in this slide deck and it was even more valuable when it was presented in person.

Thank you to UL for allowing me to share this information.

What the fire services need to know about CLT

Tall Timber buildings are now a code requirement. How is this going to impact your jurisdiction?  There will be a number of variables and one certainly should be the opinion of the men and women who will be responsible for fighting fires in such structures. In honor of these individuals here is a FIREHOUSE article on the topic so you can see what fire fighters think about tall timber construction.

A discussion of Cross Laminate Timber construction at UL Future Built Forum- Jan 2019

Thank you to UL, FDNY & IAFF for hosting the future build forum last winter. Today I would like to share with you a slide deck from a presentation by Susan Jones of AtelierJones Architects. While this is nothing more than the slide deck that she used for the presentation, it is nothing compared to what you would have heard if you were in the audience with me. She is passionate about the use to CLT (Cross Laminate Timber) as a way to build high rise structures and preserve the forests.

In this presentation you will see the home that she built with this material. She shared her passion and her story on this chilly January day earlier in the year and I hope you find value in getting a glimpse of what she share with us that day. You can view the presentation here. You will see photos CLT projects as well as of the fire tests where you will see “cribs” of wood to simulate additional fuel sources and explanations of the codes we will see in the 2021 IBC.

If you have any questions about CLT, I would love to be a resource for you but I am still learning about it myself and I am still on the fence in several ways. I hope to be able to share a stronger stance one way or another with you as things unfold more.

For now however, if you have questions about firestop on a project you are involved with do not hesitate to reach out to me. I am happy to support you if I am able.

UL Future Built Forum Intro

January 2019 in the middle of a “Polar Vortex” I attended an event that was worth braving the cold for.

I wish I could take you back to the event so you could sit in the room and hear the presentations. The speakers were fantastic and the presentations were PACKED with information. I want to thank Underwriters Laboratories, Fire Department City of New York  and International Association of Fire Fighters for sponsoring such a great event and I hope to be able to attend the next one. I learned not only from the presentations but from conversations with others in attendance who were all eager to learn and share. Can you tell I was in fire geek heaven for two days?

I can’t wait to share all of this with you. UL has generously allowed me to share the slides. Here is what they covered int he two days

There were several discussions about Tall Timber construction. they were presented by architects and fire officials. You likely know that the 2021 code will allow Tall Timber, or cross laminate timber up to 18 stories. Many people think, “WOOD BURNS that is a horrible idea!”  Well, wood does burn, that is a fact. Lets look at a few there facts.

  • ICC has reviewed extensive fire test data provided by the industry and approved it.
  • These buildings are going up all over the world. A quick google search will give you an idea of where and how tall.
  • Steel is strong, but according to this article in Fire Engineers it will lose its structural stability at 1100F. The time temperature curve used by US fire tests will require the temperature to be 1000F at the five minute mark and 1300F at the ten minute mark. Without properly applied protection, steel is very weak in a fire.
  • Wood burns, yes. As it burns that char that is created insulates the inner layer of wood and the structural stability of wood is lost in stages rather than all together upon hitting a critical temperature.

Before you dismiss this  idea of tall timber buildings as crazy,  I encourage you to learn more about it. If you are curious about my personal opinion (or even if you aren’t, you are about to get it) I like what I have seen in the fire data that has been presented. It is impressive, but not yet extensive. I am still on the fence, but I am eager to be involved with a CLT project so I can learn more. One thing I have learned is that QA/QC will be CRITICAL. Not that it is unimportant in concrete buildings or wood framed buildings, but it could prove a greater liability to those contractors who are not completely educated or worse willing to cut corners. If you work on a CLT project you can NOT have someone with the “we have always done it this way” mentality, because this is all new.  If you are working on a CLT project and want help with the QA/QC please call me.

The second discussion was on battery storage inside buildings. I did not attend this segment because of other obligations. I was able to return in time for the discussions on exterior facades and high rise fire fighting challenges.

I will share all the slides and I may share some of my thoughts along the way.

I want to again thank all of those involved in this event, the sponsors, the speakers, the organizers and the attendees. I was honored to be among you all and grateful for all you shared with everyone.  I hope to be able to attend any future events you have.
