AWC, WoodWorks Guide Mid-Rise Wood Building Through Approvals
As a result of a coordinated effort between American Wood Council and WoodWorks, a mid-rise wood building that uses cross-laminated timber (CLT) is on an approval track to grace the Austin skyline. WoodWorks’ Robbie Kelly, southwest regional director, met an architect at a local conference who wanted to deploy CLT but wasn’t able to persuade city officials, who had concerns about whether the assembly could meet the required one-hour fire resistance rating.
Officials initially objected to the fact that CLT isn’t recognized in the 2012 International Building Code (IBC), which is the code currently used by the City of Austin. Although CLT is not mentioned or defined in the 2012 IBC, thanks to AWC’s work it is included in the 2015 version of the code and the 2015 National Design Specification® (NDS®) for Wood Construction.
WoodWorks’ success advancing the project at 901 East 6th Street in Austin turned on its ability to connect the pieces and minimize confusion. In addition to extensive communication between Robbie and the project team, members of WoodWorks staff flew to Austin to accompany the architect and developer in a meeting with city officials. WoodWorks collaborated with AWC to create a concise document designed to help the building department navigate pertinent code provisions, newly developed standards, and relevant research.
The City accepted the char calculations submitted by the structural engineer as a means of providing 1‐hour fire resistance and approved CLT for use in the building’s floor/ceiling assembly. The project is currently under construction and will utilize 1.6 MMBF of lumber.

AWC Releases Revised Fire Resistance Technical Report
The American Wood Council (AWC) has released a revised Technical Report 10 (TR10): Calculating the Fire Resistance of Exposed Wood Members. New sections now support the use of a mechanics-based design method for determining the fire endurance of exposed cross-laminated timber (CLT) in accordance with the 2015 National Design Specification® (NDS®) for Wood Construction. Wood members, including mass timber products such as cross-laminated or nail-laminated timber, can be designed so that a sufficient cross section of uncharred wood remains to resist loads for the required duration of fire exposure. Recent testing of CLT, as outlined in the revised TR10, has verified this approach. Future fire testing should provide data for inclusion of additional mass timber products.

Wood, Naturally Partners with Simpson Strong-Tie on Deck Safety
Wood, Naturally’s focus on corporate partnerships to expand the campaign’s reach continued its momentum this month with Simpson Strong-Tie. The campaign teamed up with the fastener company to create an article on annual check ups to ensure deck safety, with tips from both a licensed contractor and a Simpson Strong-Tie representative. The content, which supports proper use of softwood lumber and long term enjoyment of wood decks, educates homeowners and contractors about the importance of three key steps: building to code; checking wood and deck connections; and inspecting flashing.
The article has reached an audience of nearly 64 million people and appeared in online publications such as the LA Times, Houston Chronicle, SF Gate, Chicago Tribune and many more.

reThink Wood Report Makes a Strong Case for Green Design
reThink Wood’s new document “Key Elements of Green Design” makes a multi-faceted and persuasive argument in favor of applying sustainable design and construction principles to build structures that use less energy, water and materials, and minimize impacts on human health and the environment. The colorful brochure, which you can download here, serves as an excellent overview and introduction to sustainable building principles.

Industry News

The Wood Industry is a Looming Critical Threat
Citing the results of SLB funded programs, in particular WoodWorks and reThink Wood, the concrete industry’s largest associations are joining forces to address the threat. The associations note the wood industry’s aggressive work to gain market share and address codes, especially in commercial and mid-rise construction. “Projects which used to be 4,000-5,000 cubic yards [of concrete] are now being done with only 2,000, and wood from the first floor up” says one concrete manufacturer. 
All-timber, 5-story Radiator Building Serves to Teach the Community the Benefits of Wood

The Radiator building in Portland, Ore. has helped kick off a heavy timber building room in the city, proving the financial viability of building larger buildings in wood. The building anchors a community-wide effort to incorporate healthy living into building and neighborhood design. While LED lights and building envelope efficiency have become the baseline standard in Portland, the Radiator moves the conversation on sustainability away from light bulbs and on to the harvest and manufacturing of natural resources into building materials. The building developers, Kaiser Group, are also working on the eight-story Carbon12 building in Portland, which is receiving SLB research funding.
Architect Touts “The Beginning of the Timber Age”
A November article in Dezeen magazine spotlighted a 121-unit, London housing project called Dalston Lane that will use a record amount of cross-laminated timber. The article quotes the UK architect Andrew Waugh about the advantages of wood construction, saying it is "super fast, super accurate, and also makes the most amazingly beautiful spaces. Waugh added that, “This is the beginning of the timber age.”
Glulam Featured in New Portland Office Building
“The heavy-timber creative office craze continues in Portland” with the near completion of a new 5-story building made with Glulam. “You’re basically in a post-and-beam constructed building,” said developer Urban Development + Partners. For photos of the building click here.

Oregon Partners Launch Cross-Laminated Timber Contest
Oregon BEST and a newly established collaboration between Oregon State University and University of Oregon are jointly sponsoring a contest that seeks to identify a ”keystone” CLT project that will “generate transferable information and tools” that advance the use of CLT in future construction projects.
