We ask: If the 19th century modern building material technology was associated with steel and the 20th century with concrete, could the 21st be the century of “MCT,” mass construction timber? Wood, one of the world’s oldest (and greenest) building materials, was the de facto construction material in American cities for over two centuries, falling out of favor when non-combustible materials capable of building high and wide emerged.
Today, highly engineered timber, sized to compete with these structural systems, is making a comeback in Europe, especially in Germany and in Austria, where the world’s first 8-story “ply-scraper” was recently completed. Stateside, the Boston Society of Architects recently featured Urban Timber, an exhibit showcasing innovative developments in wood technology and construction, and the U.S. Department of Agriculture is sponsoring a $2M ideas competition for the design of tall wood buildings. Given all of this hoopla, one could assume that we are on the verge of a global timber revolution, yet the U.S. is lagging far behind our European neighbors. In fact, to date, neither the U.S. nor Canadian building codes explicitly recognize mass timber structural systems.
Deeply committed to sustainability, we made the choice to dive feet first into connecting with the past to build the future by employing MCT for the primary structural system of our University of Massachusetts Amherst Design Building. Designed with Equilibrium Consultants, one of the world’s foremost timber engineers, the building will house the university’s Departments of Architecture, Landscape Architecture, Regional Planning, and Building Construction Technology, and is now under construction. Permitted through a variance application using the “alternative” method provisions of the building code, our 87,000-square-foot building furthers the university’s educational mission by incorporating examples of the inherent departments’ design practices. Targeting LEED Gold, it will be among the first MCT structures in the region when completed in 2017.
Laminated technologies, first developed in Europe in the 1980s, are allowing us to fabricate fairly massive timber components for the Design Building using small diameter trees sustainably harvested from managed forests. Our selected timber, black spruce, was sourced from Canada’s Boreal forest region, an area that constitutes the world’s largest land based biome. It is constituted to stand up to fire and maintain its structural integrity.

The American Wood Council has been awarded a $250,000 grant from the U.S. Department of Agriculture (USDA) to conduct research on the fire performance of mass timber buildings. AWC will partner with the National Fire Protection Association’s (NFPA) Fire Protection Research Foundation and the Property Insurance Research Group.
The AWC proposal is intended to advance the construction of taller wood buildings in the United States by demonstrating the fire performance of newer mass timber products. Over the last several years, tall wood buildings have been completed around the world using this new technology – including a 9-story building in London, 10-story in Prince George, Canada, and 14-story building now under construction in Bergen, Norway. These buildings have consistently demonstrated the successful application of mass timber technologies.
“Findings from this project will inform the building community and the insurance industry, providing an increased level of confidence in both the adequacy of this new construction type and when setting fire insurance premiums. This is a new method of construction to insurers, and in order to provide reasonable insurance coverage, they need to understand the performance of the material,” said AWC Vice President of Codes & Regulations Kenneth Bland. Increased use of wood in building construction also holds great promise for improved environmental impacts.
“Innovative mass timber wood products encourage sustainable forestry and capture large amounts of carbon, thereby reducing greenhouse emissions through both sequestration and the substitution of wood for more carbon-intensive products. The construction of tall wood buildings would put America at the forefront of an emerging global opportunity,” said AWC President & CEO Robert Glowinski.
When announcing the USDA 2015 Wood Innovations grant recipients, Agriculture Secretary Tom Vilsack said, “Working with our partners, the Forest Service is promoting deployment of new technologies, designed to support new market opportunities for wood energy and innovative wood building materials.”

U.S. Sen. Jon Tester, D-Mont., helped secure a $250,000 grant from the U.S. Department of Agriculture for SmartLam, a cross-laminated timber manufacturer and distributor in Columbia Falls.
In January, Tester wrote a letter of support for SmartLam’s Wood Innovations Planning Grant application. The grant was announced last week.
“The folks at SmartLam are producing a unique product, and these additional resources will help them continue to grow and hire folks in the Flathead Valley,” Tester said in a news release. “Successful operations like SmartLam continue to show the country the high quality businesses here in Montana.”
SmartLam is the first manufacturer and distributor of cross-laminated timber products in the United States. When its expansion is complete, it will be the largest cross-laminated timber manufacturer in the world.
Wood Innovations Grants are awarded to companies that use wood products as a renewable energy source and as a building material. The money is designed to increase the use of wildfire fuel from public lands to promote forest health and create jobs.
