Officials with Oregon State University are investigating a construction incident when a CLT panel failed in mid March at a campus building project. A 4×20 ft. panel, part of the sub flooring between the building’s second and third floors, gave way after delaminating on one end. No construction personnel were in the area and no one was injured. The panel was replaced, other sections of CLT sub flooring were shored up, and work was halted on other CLT sections.
Steve Clark, OSU vice president of marketing and university relations, said the university is bringing in an outside engineering firm to determine cause of the failure and whether any other CLT portions of construction were at risk of failure, and CLT work will resume once any issues are addressed. Ironically, the new Peavy Hall building is home to OSU’s renowned College of Forestry, and the building is designed to showcase Oregon’s forest industry and the relatively new (in North America) mass timber construction movement. However, Clark says project managers “have the utmost confidence in CLT” and plan to finish the project as designed using CLT. The project’s CLT panels are being supplied by D.R. Johnson Lumber of Riddle, Ore., which was the first U.S. producer to gain CLT certification in 2016.

Washington State legislators changed building codes in new legislation, a move expected to increase in the use of mass timber products in commercial and residential construction.
The Washington Forest Protection Association says the move will boost business for rural communities and forest landowners and will lead to an increase in the use of mass timber products in commercial and residential construction.
Mass timber products like cross-laminated timber (CLT) have been on the upswing in Washington in recent years, with Vaagen Brothers Lumber of Colville. Wash., and Katerra, a California company both announcing CLT factories in Eastern Washington. The material is increasingly being used in buildings around the state, according to the Washington Forest Products Association.
For Katerra, founded in 2015, CLT is an element in a broader strategy for resetting the building and construction industry. The company announced $865 million Series D funding round led by the SoftBank Vision Fund to fund its new plant in Washington, and it has already accumulated more than $1.3 billion in bookings for new construction, spanning the multi-family, student and senior housing, and hospitality sectors. It already has a fully operational manufacturing facility in Phoenix.
“The $12 trillion construction industry is extremely fragmented with tens of thousands of companies using minimal levels of technology. While labor-productivity growth has skyrocketed in the overall global economy, the construction industry has averaged only 1% annual productivity growth over the past two decades,” said Jeffrey Housenbold, managing partner for SoftBank Investment Advisers. New investors in Katerra’s latest the round include the Canada Pension Plan Investment Board (CPPIB), a private investment fund managed by Soros Fund Management LLC, Tavistock Group, Navitas Capital, DivcoWest, and others.

Modular construction, using timber as a key element, is a credible solution to fast and sustainable house building. However, Metsä Wood believes that more needs to be done in terms of sharing knowledge and innovation in wood construction to further advance the use of this material in mainstream construction.
In order to help facilitate this process, Metsä Wood has launched its Open Source Wood initiative at www.opensourcewood.com. Metsä Wood’s Executive Vice President, Esa Kaikkonen, explains: “Not enough knowledge about modular wood design and building is shared, so wood construction remains niche. There is plenty of innovation but it is difficult to find, so Open Source Wood is our solution. We believe that with open collaboration the industry can achieve significant growth.”
The potential of wood is undeniable and today, offsite construction has major aspirations. Prefabricated wood elements enable fast, efficient and environmentally sound design without reducing quality. Reports on the benefits of such a lean approach are compelling: In a study of companies that have applied lean construction methods, 84% report higher quality in construction and 80% experienced greater customer satisfaction.
The report also highlights that almost 70% of projects that used prefabricated elements had shorter schedules and 65% had decreased budgets. Timber prefab construction also reduces other inconveniences such as the constant unloading of building materials, as well as the amount of on-site waste and the need to transport it.
Innovation in the house building sector is key, and offsite timber construction could be key in achieving the high volume of housing required. Using new and innovative products like Metsä Wood’s Kerto LVL (Laminated Veneer Lumber), homes constructed offsite can be turned around in a matter of weeks. Modern engineered wood products can be used for a variety of housing projects ranging from terraced and detached homes through to apartment blocks several stories high.

American Wood Council released the following statement regarding the U.S. House of Representative’s passage of the Resilient Federal Forests Act of 2017 (H.R. 2936). The bill (H.R. 2936) includes the research title of the Timber Innovation Act (H.R. 1380/S. 538), which would establish a performance driven research and development program for advancing the use of innovative wood products in building construction.
“The United States has an opportunity to help bring an innovative and sustainable technology to our nation’s construction industry,” said AWC president and CEO Robert Glowinski.
“This bill includes language directing the technical assistance and research components already in place at the U.S. Department of Agriculture to facilitate the use of these innovative wood products into mainstream construction through research and development, education, and technical assistance. Supporting mass timber construction is a win-win because it would introduce new carbon-neutral building materials to our urban areas, as well as job creation in rural areas.”
Congressmen Bruce Westerman (R-AR), Mike Conaway (R-TX) and Mike Thompson D-Calif.) helped sponsor and advance the bill.

As a crane lowered a glulam beam and construction workers on either end deftly guided it into connection with two upright wooden columns, a tour group member shook his head and said, “It’s like Lincoln Logs.”
Kind of. Which may in part explain some of the attraction of builders and designers to the potential use of strong, precisely engineered, carbon-storing wood beams, columns, wall panels and floor decking. As Chris Evans, a Swinerton Builders project manager put it, wood is the first building material people use to make the forts, homes and hideouts of childhood.
These days, builders and designers are joining mill owners, university researchers and policy makers in taking a fresh look at advanced wood products, “mass timbers” and what’s come to be called “tall wood” design. Advocates believe it can replace concrete and steel in mid- to even high-rise buildings, and provide an economic jolt to rural Oregon in terms of forest management and mill jobs.
In Hillsboro, Evans and Swinerton Builders are overseeing construction of the largest known U.S. building to date that uses cross-laminated timber, or CLT, for flooring, and glulam posts and beams. The Oregon headquarters of First Tech Credit Union will be five stories high and have 156,000 square feet of office space. Swinerton Builders is the general contractor.
Another tall wood building planned for Portland, called Framework, will be 12 stories high and will have five floors of affordable housing. That project was awarded a $1.5 million federal design competition grant to help with seismic and fire testing and certification.
