Oregon Senators Urge Timber Innovation Act To Be Included In Farm Bill

by | May 24, 2018 | News

Oregon’s U.S. Senators Jeff Merkley and Ron Wyden recently submitted a bipartisan letter urging the Committee on Agriculture, Nutrition and Forestry to include the Timber Innovation Act, which supports the development of mass timber products for building construction, in the next Farm Bill.

“We have been working to establish Oregon as a hub for mass timber products, using local timber and bolstering our forest products economy,” Merkley said. “This bill supports innovative manufacturing that creates jobs in the rural part of the state and encourages more sustainable tall wood building construction in urban parts of the state.”

“Oregon is leading the way in producing and engineering cross-laminated timber, which is revolutionizing the way our country constructs buildings,” Wyden said. “The Timber Innovation Act promotes job growth in Oregon’s timber counties and encourages the kind of Oregon entrepreneurship that can catapult our state’s economy to new heights.”

Merkley is co-leading the letter with Sen. Mike Crapo (R-ID); cosigners include Sens. Wyden, James Risch (R-ID), Amy Klobuchar (D-MN), Steven Daines (R-MT), Roger Wicker (R-MS), Gary Peters (D-MI), Angus King (I-ME) and Maria Cantwell (D-WA).

Oregon has been at the forefront of developing mass timber products, including includes cross-laminated timber (CLT), nail laminated timber, glue laminated timber, laminated strand lumber, and laminated veneer lumber. However, U.S. building codes do not currently recognize mass timber products as official construction materials, leaving the products without a standard rating system for quality, fire resistance, earthquake resistance, and more.

Rise Of Mass Timber Buildings Showcase Its Increasing Credibility

by | Jan 29, 2018 | News

New mass timber products are becoming more widespread and encouraging builders, designers, and engineers to search for the best applications for mass timber initiatives. A few of the mass timber building products available today include:
• Cross-laminated timber
• Nail-laminated timber
• Glue-laminated timber
• Dowel-laminated timber

As they test the capabilities of these materials, designers are looking to existing mass timber buildings around the world for examples and inspiration.

Canadian and European researchers and architects began experimenting with the design of mass timber buildings in the 1970s. European timber projects have shown that weight matters with structural systems, and mass timber structures weigh up to one-third as much as their concrete counterparts. This fact has made wood construction a viable prospect in places where building height and weight are limited, such as city utilities, subway tunnels, and underground rail yards.

Due to their lighter weight, mass timber buildings are more resilient in seismic zones. They carry less inertia, so the possibility of destructive swaying goes down. This approach was recently applied in the Brock Commons tower, an 18-story college residence designed for the University of British Columbia by Canadian firm Acton Ostry Architects.

The 173-foot-tall tower combines glue-laminated columns, cross-laminated timber floor slabs, dual concrete cores, and steel connectors. The cores help to counteract wind-generated and seismic forces while anchoring the mass timber building in place. It meets structural and fire-safety regulations by utilizing a specially designed set of interdependent finishes and building materials.
