Timber construction is opening a new market that has been keeping lumber and milling machinery busy at a growing number of wood products companies, including Montreal’s Nordic Structures, Sauter Timber in Rockwood, Tennessee, SmartLam, in Columbia Falls, Montana, and D.R. Johnson, in Portland, Oregon.
Oregon-based D.R. Johnson Wood Innovations, a subsidiary of D.R. Johnson, specializes in the manufacture of cross-laminated timber, or CLT, and glue-laminated beams from Douglas fir and Alaskan yellow cedar. D.R. Johnson Wood was the first U.S. company to receive APA/ANSI certification to manufacture structural CLT panels – and CEO Valerie Johnson plans to help grow the U.S. market.
D.R. Johnson has received the first U.S. certification to manufacture cross-laminated timbers (CLT) under a new standard approved last year by the American National Standards Institute. D.R. Johnson is one of only three North American companies certified by the Engineered Wood Association to construct CLT for use in buildings.
Johnson’s company employs 125 at a traditional sawmill and laminating plant, which was recently expanded by 13,000 square feet for increased CLT production. They’re currently fielding calls from hopeful builders, and manufacturing samples to be tested for fire safety and structural quality. One recent new wood construction project is a 14-story wooden apartment tower being built in Portland, Oregon.

Videos are now available showing a series of live blast tests on three cross-laminated timber (CLT) structures at Tyndall Air Force Base, conducted by WoodWorks in cooperation with the US Forest Service and Softwood Lumber Board. Post-test observations were exciting. All structures remained intact and matched modeling predictions with acceptable levels of damage under significant explosive loading. The results of this testing will be used to further expand the use of wood solutions for Department of Defense applications and other blast-resistant construction.

The CLT structures—each two-story, single-bay structure with anchorage to an existing concrete slab—were constructed in full by Lendlease over a period of eight days. Each structure was constructed using a different grade of CLT (i.e., grade designations V1, E1 and V4 per ANSI/APA PRG-320 provided by DR Johnson, Nordic and SmartLam, respectively) and included window and door openings (with doors provided by American Direct) consistent with an actual building. Self-drilling screws provided by MyTiCon and adhesive anchors provided by Hilti were utilized in concert with angle steel to connect the constituent panels of each structure.
Three shots were performed to demonstrate the effectiveness of CLT over a spectrum of blast loads. The first two shots were designed to stress the CLT structures to within their respective elastic limits. The third shot was designed to push the structures beyond their elastic limits such that post-peak response could be observed. Reflected pressure and peak deflections were recorded and will be used to thoroughly document the response of the structure in time, and support a design methodology for predicting elastic response of CLT under dynamic loads.
Initial observations deriving from these tests are positive. For the first two tests, peak recorded deflections were consistent with pre-test predictions, indicating the efficacy of the design assumptions and supporting design methodologies. Results from the third test indicated a controlled response in which localized panel rupture was observed but connection integrity and load carrying ability were not compromised for any of the three structures. Over the next couple months, WoodWorks will be working with Karagozian & Case, Inc. and the University of Maine to thoroughly post-process and analyze the results of these tests.

If the vast potential of timber construction isn’t obvious, a new exhibit at Washington D.C.’s National Building Museum aims to clear things up. Running through May 2017, the USDA-sponsored Timber City is drawing attention to the recent boom in a worldwide movement toward timber construction.
It’s opening up a new market that has been turning the mills at a growing number of wood products companies, including Montreal’s Nordic Structures, Sauter Timber in Rockwood, Tennessee, and D.R. Johnson.
Oregon-based D.R. Johnson Wood Innovations, a subsidiary of D.R. Johnson, specializes in the manufacture of cross-laminated timber (CLT) and glue-laminated beams from Douglas fir and Alaskan yellow cedar. They’re the first U.S. company to receive APA/ANSI certification to manufacture structural CLT panels – and they hope to help grow the U.S. market.

They’re currently fielding calls from hopeful builders, and manufacturing samples to be tested for fire safety and structural quality.
D.R. Johnson says the system for constructing CLT involves assembling prefabricated parts, speeding construction, and paring labor costs. The company partnered with wood processor manufacturer USNR to build a custom panel press for CLT.

Like much of the industry, engineered wood producers are still navigating a fickle recovery in which builders are challenged by supply constraints, tight lending, and hard-to-come-by lots. Though the market is emerging from the recession, it’s still on the slow side.
“The demand is there for 1.5 million housing units. We’re not meeting that,” says Joe Elling, director of market research for APA–The Engineered Wood Association. Production is up on a year-ago basis, “but starts could be stronger if some of these supply-side constraints were not as binding,” Elling says. “I anticipate a modest improvement in the second half of the year, but it’s still going to be agonizingly slow going forward.”
For engineered lumber manufacturers and the dealers who sell their products, the slow recovery presents both challenges and opportunities. Along with the obvious—a slower return to at-peak sales—the ongoing labor shortages have created an even stronger need for product education. At the same time, those labor constraints provide even more motivation toward using engineered products that boost efficiencies and cut back on waste.
Overall, the industry has seen a positive boost in public opinion toward wood products, be they engineered or otherwise, as high-profile projects showcase their capabilities, beauty, and warmth.
“One of the biggest things in the forest products industry today that affects EWP the most is the general feeling in the world that wood is good,” says Mike McCollum, director of engineered wood business at Roseburg. “Wood is now the first choice in everybody’s eyes. Its sustainability, its efficiencies, its workability, its natural warmth, along with the fact that it is easy to design with and easy to build with…everyone has been awakened to this idea that wood is good. Then, when you take it to the next step, everything that engineered wood brings to the construction market is highlighted even more.”

The 2016 Structural Panel & Engineered Wood Yearbook has been released by APA – The Engineered Wood Association. The yearbook includes an analysis of the U.S., Canadian, and global economies, focusing on factors that impact demand for engineered wood products across several market segments as a basis for forecasting expected production of engineered wood products over the next five years. Besides the analysis and forecast, the yearbook also includes historical data on engineered wood production. Topics examined in the yearbook include:
• U.S., Canada, and World economies
• Residential construction in the U.S. and Canada, new and repair/remodel
• Nonresidential and industrial markets
• North American imports and exports
• Outlook and production statistics for structural panels (OSB and plywood), including historical data
• Engineered wood product demand and production (glulam, I-joists, and LVL)
Driven by healthy employment gains over the last three years, annual household growth in the U.S. is back to the 1.2 million level, with demand for new housing units also back to the 1.5–1.6 million unit level. Buoyed by low interest rates, which are expected to remain below 4 percent for most of 2016, construction of new single-family homes in the first quarter of 2016 was up almost 5 percent from the pace of the fourth quarter of 2015, the highest quarterly starts rate since the fourth quarter of 2007. While demand is high in the U.S., the primary concern for the rest of 2016 and for the next several years is the ability of the supply-side forces to respond to this improvement. Home builders report that factors including a lack of developed lots and the shortage of skilled construction labor have combined to constrain their ability to respond to the increased demand for housing. Eventually these constraints will lessen; housing starts are projected to return to approximately 1.5 million units by decade’s end, with a concurrent growth in engineered wood products output ranging from 19–28 percent during this period.
