SOM Tests Its Latest In Timber Tower Technology

Working with Oregon State University (OSU), Skidmore, Owings & Merrill (SOM) has been busy testing its design for a timber tower. The time-lapse video shows a section of the wood tower being submitted to 82,000 pounds of pressure.

SOM has been working on the Timber Tower Research Project, funded by the Softwood Lumber Board (SLB) since 2013. The goal of the project is to develop safe, sustainable building technologies using mass-timber. Using timber may reduce a building’s embedded carbon footprint by as much as 60% to 70% compared to benchmark concrete building. The Timber Tower Research Project has developed a structural system called the Concrete Jointed Timber Frame that employs mass-timber elements with reinforced concrete connections.

Since 2014, SOM and OSU have developed a comprehensive physical testing program, which recently completed a full-scale test to prove the system’s ability to satisfy code requirements. The 36-foot by 8-foot specimen is comprised of a Cross-Laminated Timber (CLT) deck topped with a thin layer of reinforced concrete. The concrete is used to improve structural, acoustic, and fire performance. The composite allows for long spans with a relatively thin cross-section. The 82,000 pounds tested is roughly eight times the required design load. Forty-eight sensors recorded stresses as a hydraulic actuator loaded the specimen over two hours.

World’s Tallest Timber Building Topped Off Ahead Of Schedule

In Vancouver, Canada, the towering timber Brock Commons just had its final panel installed, making the dream of the world’s tallest timber building a reality, reports the website Inhabitat.

In just 66 days – ahead of the original scheduled timeframe – the exterior of the Acton Ostry Architects‘ record-breaking design has come to fruition, which could bump up the projected fall 2017 completion date to next year’s spring semester. The final panel of the University of British Columbia student housing structure was lifted and installed earlier this month.

John Metras, managing director of UBC Infrastructure, said, “Construction just went really smoothly. It was well designed and the construction sequence went smoothly.”

Construction began last November, followed by the erection of the building’s freestanding concrete cores earlier this year.

To ease fire safety fears of an 18-story timber structure, Brock Commons is outfitted with a sprinkler system and the wood is encapsulated in drywall and concrete. The lighter weight of the building also allows for better energy dissipation during an earthquake, making it proficient at withstanding all kinds of disasters. Students will be able to move in next year, quite possibly in the spring semester.

Arauco To Complete New Plant In 2018

The $325 million particleboard plant Arauco is constructing in Grayling, Mich. will not only be the largest single-line capacity particleboard plant in North America, but it also represents the first greenfield particleboard plant constructed on this continent since 2001, according to Arauco North America President Kelly Shotbolt.

“When completed in late 2018, it will bolster our commitment to servicing customers, especially those in the Midwest and Eastern Canada,” Shotbolt says. “We’re currently laying the groundwork needed to proceed with construction: clearing the site, securing environmental permits and hiring a management team. At the same time, we’re enjoying getting to know our Grayling neighbors. The city has been a fantastic partner and we look forward to being a member of the community and providing career opportunities for many local residents.”

Jake Elston, Vice President of Operations for Arauco North America, adds,  “This is definitely one of the most exciting things many of us have ever been involved with in our careers. This mill will utilize the newest technology available in the industry. It will truly be a state-of-the-art composite panel mill.”

The entire operation will be situated on one square mile located in north central Michigan. The plant will occupy approximately 750,000 sq. ft. under roof. A 170-foot long by 10-foot wide Dieffenbacher continuous press line housed in it will have an annual production capacity of 424MMSF of particleboard on a ¾ in. basis.

Plans for the operation also include installation of a decorative paper impregnation system and a pair of thermally fused laminate lines sold under the company’s new Prism TFL brand.

Elston says a project milestone was recently observed when the company hired Charles Mason as a site drafter. Mason became the first of many area residents who will be hired to operate the plant.

“We’ve had our internal design team of Tex Giddens, Goran Oscarsson, Manfred Timmerman and Mike Battisti working nearly full time with our strategic planning and engineering teams in South America for over a year. As the first local employee, Charles is working with this group to come up to speed on vendor contracts and also starting to support local issues in the Grayling community,” Elston says. “We will start hiring select plant leadership and construction management personnel by the end of the year.”

Elston adds that Arauco North America will be leasing temporary office space in downtown Grayling to support employees during construction planning and building phases. The facility is expected to eventually employ 250.

Arauco has applied for environmental permits with state and local agencies. Elston says approval is expected in mid-August.

In the meantime, work has begun to remove trees and underbrush from the building site, prerequisite preparations to add roads and utilities to service the plant. If all goes according to plan, groundbreaking for the plant will commence this fall after permits are issued.

“It’s a very aggressive timetable to have the plant start up by the end of 2018. When you take into account Michigan winters, that’s really only 18 to 20 months to bring a mill of this size and capacity up to fully functional.”

Elston notes that the Grayling location is ideal for the new particleboard plant for a variety of reasons. “The upper Midwest region—with the office furniture industry, RTA industry, cabinets and others—is the largest panel consuming region in North America. Michigan is a good fit to serve this market because it has available wood fiber, including residual wood from some nearby sawmills, and is logistically closer to many significant customers that are currently being served from suppliers much farther away.”

Elston emphasizes that the use of low value fiber that is currently underutilized in the area should be a win-win for Arauco, Grayling area landowners, and the community as a whole.

The commitment to build the Grayling facility comes on the heels of an important $30 million investment to upgrade and expand the Arauco particleboard plant in Bennettsville, SC, where the company added a new drying area that increases the plant’s annual capacity by 50MMSF of raw particleboard, and also added a fast-cycle press to double the plant’s output of thermally-fused laminate panels.

Lumber Liquidators Wins Formaldehyde Settlement, Opponents Pay Legal Fees

Lumber Liquidators, the largest specialty retailer of hardwood flooring in North America, recently announced the final resolution of the Proposition 65 lawsuit originally filed on July 23, 2014, in the Superior Court of the State of California.

On June 30, 2016 the Court entered judgment in favor of Lumber Liquidators.  On August 12, 2016, the parties entered into a final resolution of the case, with a settlement agreement that requires the plaintiffs to pay Lumber Liquidators $100,000 as reimbursement for costs. The agreement also requires the plaintiffs to surrender their right to appeal or challenge the judgment.

“The verdict in our favor in the Proposition 65 case and the related settlement requiring plaintiffs to reimburse our costs are additional steps forward in the tremendous progress our company has made over the past several months,” said John Presley, CEO of Lumber Liquidators.

“We have strengthened Lumber Liquidators across every area of our organization, including implementing significant enhancements to our sourcing and compliance practices, and look forward to continuing to deliver products that are compliant with California’s environmental standards. As a company, we remain committed to operating with integrity and delivering the highest quality products to our customers.”

In 2014, Global Community Monitor and Sunshine Park LLC filed a lawsuit claiming that Lumber Liquidators failed to provide a Proposition 65 formaldehyde warning to California consumers. The Court ruled that the plaintiffs’ evidence failed to support their claims.

APA Releases 2016 Structural Panel & Engineered Wood Yearbook

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.

Huber Sues GP For Infringement

Huber Sues GP For Infringement

 

googletag.cmd.push(function() { googletag.display('div-gpt-ad-1548376180744-0'); });

Huber Engineered Woods LLC has filed a patent infringement lawsuit against Georgia-Pacific Wood Products LLC, alleging that GP’s ForceField Air and Water Barrier System infringes Huber’s patents for its ZIP System sheathing and tape products. Huber filed the lawsuit in the United States District Court of the Western District of North Carolina.

“For more than two decades, Huber Engineered Woods has provided innovative, premium and branded solutions to its customers and builders,” says HEW President Brian Carlson. “We have consistently invested to develop a broad portfolio of patents to protect our branded products, including ZIP System sheathing and tape products and AdvanTech flooring and sheathing panels. We will vigorously defend our patents against infringement.”

Since its introduction in 2006, ZIP System sheathing and tape has been used by many builders as a replacement for traditional sheathing and housewrap. The exterior wall and roof system consists of an enhanced moisture-resistant, engineered wood panel with a built-in, water-resistive, vapor permeable barrier that eliminates the need for housewrap or felt. Completed with taped panel seams using ZIP System flashing tape, the system helps protect construction timelines by creating quick dry-in status and reducing risk of rework, while providing moisture protection and reduced air leakage, according to a Huber statement.

Specifically, Huber alleges that the ForceField products marketed by Georgia-Pacific infringe two patents when used to sheath the walls of homes during construction; that the use of multiple ForceField panels to sheath the wall of a home, when sealed together with water-resistant tape such as GP’s ForceField Seam Tape, creates a panel system that infringes the two Huber patents.

Georgia-Pacific offered the following statement in response: “Georgia-Pacific Wood Products is aware of the lawsuit filed by Huber Engineered Woods related to Georgia-Pacific’s recently-launched ForceField Air and Water Barrier System. As a company that respects intellectual property, Georgia-Pacific remains confident that ForceField does not violate the intellectual property rights of others, including those of Huber. Georgia-Pacific disagrees with Huber’s allegations, and intends to vigorously defend itself in this matter.”

The Huber lawsuit states that the inventions claimed in its patents were the result of years of research and development on structural sheathing systems by Huber. “The inventions represent a leap forward in roof and/or wall structural sheathing system technology, solving several problems exhibited by other sheathing systems that rely upon house wrap or felt paper that is used with structural wood panels as part of the weatherization of buildings.”

Huber’s ZIP System sheathing was first sold in 2007. The lawsuit states that GP introduced its ForceField System in January 2016 as a competitior to Huber. “Rather than put in the time and resources necessary to independently develop a sheathing product, like HEW did, GP instead chose to take advantage of the innovative development work done by HEW,” the lawsuit states.

Interestingly, according to the lawsuit, GP hired a former Huber employee to help GP develop its product—the same person who is a named inventor on each of the Huber patents and who was involved in the development of Huber’s ZIP System sheathing and other Huber products. The lawsuit states that this person is a named inventor on GP’s currently pending patent application for the similar product technology.

Huber Engineered Woods has OSB manufacturing operations in Maine, Georgia, Virginia and Oklahoma.
