Vancouver-based real estate developer PortLiving and world-renowned Japanese architect Shigeru Ban have unveiled plans for an upcoming hybrid timber structure said to be the tallest in the world. If so, this would mean it will be higher than other CLT wood structures, such as the 34-story design planned for Stockholm.
The residential high-rise Terrace house, which will be located in Vancouver’s Coal Harbor neighborhood, may set a new standard for urban luxury in design, sustainability and engineering innovation. The high-rise will feature a cross-laminated timber frame supported by a concrete and steel core. Wood for the project will be locally sourced from British Columbia, minimizing its carbon footprint.
Cross-laminated timber has been gaining popularity as of late, due to its lightness, sustainability, and ease of use. Planks of timber are glued and orientated at 90 degrees to each other, and are then crosslaid in layers. Those pieces are then shipped to construction sites and can be assembled by just a few workers, even for large buildings.
Its use in tall wooden buildings has also been growing. London, Stockholm, and Quebec are just a few of the cities who either already have large timber towers or have one in the works. Recent plans include a Swedish firm’s 436 ft. residential wood skyscraper in Stockholm, while a 12-story mixed wood high-rise is planned for construction in Portland, Oregon.
Building codes are being adjusted in Oregon and Washington State to permit the tall wood structures. But CLT hasn’t gone without opposition.

For years, it was known as the ugly duckling, cheaper alternative to plywood. One design maven described it as “like the turkey loaf of building materials.” But oriented strand board – OSB for short – has come into its own over the past 3 1/2 decades as a major player in North American wood-frame housing construction and is increasingly used for industrial and other applications.
Structural OSB panels – made of wood strands that are resin-bonded under high pressure and heat – are mostly used as floor, roofing or wall substrate in home building. They’re also getting play these days on fashionable interior-decoration websites as a “shabby-chic” finishing material.
Capitalizing on OSB’s rise like no other forest-products company is Toronto-based Norbord Inc. Norbord, once a diversified forestry company, has shed assets over the years and focused on OSB. Now boasting annual sales in the $1.5-billion (U.S.) range and a market capitalization of about $2.4-billion (Canadian), it bills itself as the world’s largest producer of OSB.
The $763-million acquisition in 2014 of Vancouver-based Ainsworth Lumber Co. Ltd. gave Norbord – whose operations were concentrated in the U.S. southeast – a strong presence in Western Canada as well as a foothold in the promising Japanese market.
Right now, the steadily growing number of housing starts in the United States is giving Norbord a big boost, and low-key, media-shy chief executive officer Peter Wijnbergen says there are major growth opportunities in Europe and Asia.

Projects in Springfield and Portland have landed a collected $200,000 as leaders test the viability of cross-laminated timber.
The funding, awarded by the Business Oregon-backed cleantech champions Oregon BEST and the National Center for Advanced Wood Products Manufacturing and Design, will back research that fast-tracks CLT as a green construction material usable throughout the U.S.
Of that money, $155,000 will go to the planned four-story Glenwood Parking Structure in Springfield. The project’s developers will use the money for research, performance testing and code documentation. The team will measure such factors as vibration, moisture, post-tension loss in rocking shear walls and seismic instrumentation. The SRG firm designed the 360-space structure.
The National Center for Advanced Wood Products Manufacturing and Design, a collaboration between Oregon State University and the University of Oregon, will perform the research and testing functions. The Carbon 12 mixed-use condominium complex in Northeast Portland was awarded $45,000 for acoustic and moisture testing.
According to Oregon BEST, U.S. architects and builders wanting to use the new material in construction projects “must negotiate a maze of additional documentation, atypical performance modeling requirements, unfamiliar construction methods and building code hurdles that can delay CLT projects and has slowed adoption of the material.”

On Dec. 26, 2015, the first EF4 or stronger tornado ever recorded in December in Texas made landfall in Garland and Rowlett, suburban towns near Dallas. APA sent a damage assessment team to the area immediately following the storm. The damage assessment team found numerous examples of severe damage, not just in the area most intensely affected by the storm, but also in areas where the tornado winds were not as intense, with damage indicators pointing to wind speeds well below the EF4 rating.
Building failures were attributed to several common structural weaknesses, including poor performance of laminated-fiber sheathing, missing metal connectors, and poor attachment of wall systems to both the roof and the foundation.
While it is challenging to design homes to withstand the most intense tornadoes, there are cost-effective design details that builders and designers can implement to significantly mitigate storm damage in less powerful winds along the edge of the storm’s path. By continuously sheathing walls with plywood or OSB and playing close attention to all connection details, builders can significantly increase the strength and resilience of their homes.
Download Texas Tornado Damage Assessment Report, Form SP-1177, including general findings, 50 images of tornado-damaged homes, and wind-resistant construction recommendations. The report is also available to purchase in print for $2.00.

Weyerhaeuser plans to permanently close its lumber mill and plywood mill in Columbia Falls, Montana, by the end of the summer. It will also close its Columbia Falls, Montana, main office.
Weyerhaeuser will continue to operate its three other mills in Montana: a lumber mill in Kalispell, a plywood mill in Kalispell, and a medium-density fiberboard mill in Columbia Falls.
“For some time now our operations in Montana have been running below capacity as a result of an ongoing shortage of logs in the region,” said Doyle R. Simons, president and chief executive officer. “These closures will allow us to align the available log supply with our manufacturing capacity, including adding shifts at our Kalispell facilities. These moves will improve the operating performance of our remaining mills and best position these mills for long-term success.”
Some 100 jobs will be eliminated as a result of the mill closures, now planned for late August or early September.
The mill closures follow a decision earlier this year to move corporate positions that do not support manufacturing in Montana to Weyerhaeuser’s Seattle headquarters. As a result, the company also plans to close its main office in Columbia Falls at the end of the year.

The months-long mystery behind which home siding company would be receiving a $66 million subsidy package from the state has finally been made public. Louisiana-Pacific will construct a $440 million plant in Hoyt Lakes. This is the Nashville-based company’s second operation in the state (the other being in Two Harbors).
The Hoyt Lakes site will employ 250 people, amounting to roughly $264,000 in state funding per job created. The Duluth News Tribune notes that many of those employees will be loggers and felled tree transporters, a group of workers that has struggled to find employment following years of board plant closures and layoffs at paper mills in the area.
The new plant will also source its wood products from Minnesota. LP is currently estimating its take to be 800,000 cords per year (one cord equals 128 cubic feet of wood) or about 200 logging trucks each day.
Minnesota lawmakers began developing the public financing package for LP earlier in the year. Senator David Tomassoni, DFL-Chisholm, previously said at least Michigan and Canada were vying for the LP plant as well.
Funding for the project comes from a number of sources. The Minnesota Department of Employment and Economic Development will be kicking in $20 million from its 21st Century Minerals fund, while the Iron Range Resources and Rehabilitation Board will be contributing $16 million from its economic development trust fund. The final $30 million will come from state taxpayers in a 10-part, $3 million per year deal.
