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.

Officials in Oregon have approved construction permits for the first all-wood high-rise building in the nation. Construction on the 12-story building, called Framework, will break ground this fall in Portland’s trendy and rapidly growing Pearl District and is expected to be completed by the following winter.
The decision by state and local authorities to allow construction comes after months of painstaking testing of the emerging technologies that will be used to build it, including a product called cross-laminated timber, or CLT.
To make CLT, lumber manufacturers align 2-by-4 boards in perpendicular layers and then glue them together like a giant sandwich before sliding the resulting panels into a massive press for drying. The resulting panels are stronger than traditional wood because of the cross-hatched layers; CLT can withstand horizontal and vertical pressures similar to those from a significant earthquake with minimal damage. They also are lighter and easier to work with than regular timber, resulting in lower cost and less waste.
For this project, scientists at Portland State University and Oregon State University subjected large panels of CLT to hundreds of thousands of pounds of pressure and experimented with different methods for joining them together. The project materials also underwent extensive fire safety testing and met fire codes.
State officials hope the building will stir greater interest in high-rise construction using mass timber and help revitalize the state’s lagging logging industry. Logging, once a major source of revenue in Oregon, has dropped sharply in the past few decades because of greater environmental protections for salmon and the spotted owl. The loss of the industry has devastated some of the state’s rural communities.

Against a backdrop of Industry 4.0, “LIGNA 2017 will go down as a milestone in the digitalization of the wood industry,” said Dr. Andreas Gruchow, managing board member of Deutsche Messe, organizer of the woodworking industry’s largest trade show in the world.
Held May 22-26 in Hannover, Germany, the biennial show drew 93,000 visitors, including an estimated 42,000 attendees from outside the host country, according to show figures. More than 1,500 exhibitors, including 900 from abroad, showcased a range of innovative machinery, tools and solutions, with displays spanning across almost 1.4 million square feet of net space at the fairgrounds.
LIGNA 2017 featured a revamped, thematic layout, including two new display categories: Surface Technology and Machine Components and Automation Technology, which highlighted the theme of Industry 4.0: the networking of machines and automation to improve efficiency in high-production as well as small-scale environments.
“Digitalization and integrated production are the new keys to success for our customers,” added Wolfgang Pöschl, chairman of the Woodworking Machinery division of Germany’s Mechanical Engineering Industry Association (VDMA), a show sponsor, and also chairman of the management board of Michael Weinig AG. “There is huge demand across the board, resulting in full order books. The challenge now is to shorten delivery lead times as much as possible.”
Catering to the wide range and skill levels of the attendees, exhibits ranged from high-tech, sophisticated machinery to entry-level systems for use by those in the furniture, cabinet, architectural woodworking, casegoods and closets industries. Solutions shown included: service apps for machine monitoring, to the first professional table saw using SawStop technology, dual glue technology on a contour edgebander, sanding and finishing innovations, a moulder that produces lineal shapes and designs in a single step, robots, a “three-click” process for producing a complete item of furniture, and of course, Batch 1 systems incorporating CNC technology.

EPA issued a proposed Direct Final Rule, concerning formaldehyde emission standards for composite wood products, extending all of the TSCA Title VI compliance deadlines to account for the delays to the originally published effective date. The rule was published in the Federal Register May 24. The new compliance dates are as follows:
• Emissions, recordkeeping and labeling provisions – March 22, 2018
• Import certification – March 22, 2019
• Laminated products – March 22, 2024
The rule also proposes to extend the transitional period for CARB-certified third-party certifiers (TPCs) to March 22, 2019.
This proposed rule will enter into effect within 45 days of publication in the Federal Register if EPA does not receive any adverse comment within 15 days.
“The federal regulation that definitively addresses formaldehyde emissions from composite wood products sold in the United States was first published in the Federal Register on Dec. 12, 2016, by the U.S. Environmental Protection Agency. If properly enforced, the regulation can ensure that all products – both domestic and imported composite wood panels and the finished products containing them – meet the world’s most stringent standards for formaldehyde emissions. It also marks the culmination of over 30 years of product stewardship by the composite wood industry, which through voluntary efforts and consistent and progressive work with regulators, has successfully developed products that consistently meet or exceed these tough standards,” said Jackson Morrill, president of the Composite Panel Association.

One building stands out in the old logging town of Prince George, Canada. Encased in a sleek glass facade, the structure towers above most of its neighbors, beckoning from afar with the warm amber glow of Douglas fir. Constructed almost entirely from timber in 2014, the 8-story, 30-meter building is among the tallest modern wooden structures in the world. But it is more than an architectural marvel. As the home of the Wood Innovation and Design Centre at the University of Northern British Columbia (UNBC), it is also an incubator for wooden buildings of the future — and a herald for a movement that could help to tackle global warming.
The building is less like a log cabin and more like a layered cake, constructed from wooden planks glued and pressed together, precision cut by factory lasers and then assembled on site. All told, the university avoided the release of more than 400 tons of carbon dioxide by eschewing energy-intensive concrete and steel, and the building locks up a further 1,100 tons of CO2 that was harvested from the atmosphere by British Columbian trees. In total, that’s enough to offset the emissions from 160 households for a year.
Wooden construction has ancient roots, but only in the past two decades have scientists, engineers and architects begun to recognize its potential to stave off global warming. By substituting concrete and steel with wood from sustainably managed forests, the building industry could curb up to 31% of global carbon emissions, according to research by Chad Oliver, a forest ecologist at Yale University in New Haven, Connecticut. In time, such a shift could help humanity to pull CO2 out of the atmosphere, potentially reversing the course of climate change.
“It’s the plywood miracle,” says Christopher Schwalm, an ecologist at Woods Hole Research Center in Falmouth, Massachusetts. “This is something that could have a significant impact on the riddle that is global environmental change.”
