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.

Total exports of U.S. hardwood lumber and veneer to the Middle East and North Africa (MENA) region reached a record USD 108.93 million for the year 2014, according to the American Hardwood Export Council (AHEC), the leading international trade association for the American hardwood industry. The statistics, which have been compiled from the latest data released by the United States Department of Agriculture (USDA), reveal an overall 20 percent increase over 2013 figures. The announcement was made on the sidelines of the Dubai WoodShow 2015 where AHEC is hosting the largest ever American Hardwood Pavilion, featuring twenty-one U.S. hardwood lumber and veneer exporters.
According to the data released, exports of American hardwood lumber reached a value of USD 79.07 million and a volume of 98,425 cubic meters during 2014. This equates to an increase in value of 23 percent over 2013 and an increase in volume of 8 percent. Direct exports of U.S. hardwood veneers to the MENA region reached a total value of USD 29.86 million last year, rising by 12 percent from 2013. However, it is important to note that American hardwood veneers are also shipped to the region from European countries and China, while veneers are also produced in the region – notably in Turkey – from imported American hardwood logs. U.S. hardwood log exports to the MENA region reached a total volume of 34,957 cubic meters and a value of USD 20.47 million in 2014.
Commenting on the record exports to the region, Roderick Wiles, AHEC Director for Africa, Middle East, South Asia and Oceania, said: “The most significant increases in shipments of U.S. hardwood lumber were seen in the United Arab Emirates (up by 48 percent to 15,723 cubic meters), Egypt (up by 22 percent to 11,614 cubic meters), Jordan (up by 18 percent to 5,949 cubic meters), Lebanon (up by 23 percent to 4,735 cubic meters), Qatar (up by 55 percent to 3,015 cubic meters) and Morocco (up by 31 per cent to 2,329 cubic meters). However, a marginal downturn in volume of only 2 percent was seen in shipments to Turkey, which reached 12,700 cubic meters and a slight downturn was seen in shipments to Saudi Arabia, which reached 10,513 cubic meters.”

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.
