Following a seven-year study of 88 timber tracts across Oregon’s western Cascade Range, researchers have concluded no “discernable difference” in populations and occupancy of a rare salamander on recently harvested stands compared to stands older than 50 years. The project, which ran from 2013-2019, was a collaboration of Oregon State University, Weyerhaeuser, Port Blakely Tree Farms, Bureau of Land Management and the Oregon Dept. of Forestry, and the findings were published in the journal Forest Ecology and Management.

Found only on the west slope of the Cascade Range, the Oregon slender salamander is considered “sensitive” by state wildlife officials, and other groups have petitioned for its listing under the Endangered Species Act. It lives primarily underground or burrowed into decaying woody material and is found on both older age class tracts and timber plantations. Researchers did note that a more commonly found salamander was negatively affected by timber harvest, and recommended that landowners leave more moisture-holding wood on the ground after logging to provide habitat for both species.

Freres Lumber Builds For The Future With New Mass Plywood Panels

Freres Lumber Builds For The Future With New Mass Plywood Panels

Tyler Freres, vice president of sales for Freres Lumber Co., walked through a new manufacturing plant between Mill City and Lyons, off of Cedar Mill Road, and pointed out a stack of wood panels destined for Oregon State University this week. “I don’t even think we’ve started to tap the products and the projects we can make out of this,” Freres said.

Freres Lumber Co.’s mass plywood panels were certified for use at the end of July, and the product is already being used in buildings and for other construction purposes. And Freres is thinking big. “We have quite a bit of projects in the works, probably 14 to 16 projects quoted,” said Freres, whose ideas led to the creation of the mass plywood panels by his family’s company.

The OSU shipment is the final delivery of the panels to be used in two new buildings that will form the Oregon Forest Science Center on campus, which is estimated to cost $80 million and scheduled to open in the fall of 2019.

The mass plywood panels will be used for the roof of the George W. Peavy Forest Science Center, and for the interior and exterior walls of the nearby A.A. “Red” Emmerson Advanced Wood Products Laboratory.

Both buildings are showcasing innovative wood products made in Oregon, and the mass plywood panels are the latest entry into the market. Freres Lumber was only the third United States producer of mass timber panels to meet the Engineered Wood Association’s standards.

OSU Gets Grant For Cross-Laminated Timber Research

OSU Gets Grant For Cross-Laminated Timber Research

 

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

Oregon Senators Jeff Merkley, the top Democrat on the Senate Appropriations Agriculture subcommittee, and Ron Wyden announced Thursday that a nearly half-million dollar U.S. Department of Agriculture grant was awarded to Oregon State University for research on the durability of cross-laminated timber, an innovative product that is helping to advance wood as a construction material for tall buildings.

“We have been working to establish Oregon as a hub for mass timber products, using local timber and bolstering our forest products economy,” said Merkley, who each year on the Appropriations Committee has fought to fund this important grants program.

“This research at OSU supports the innovative manufacturing that helps to create jobs in the rural part of the state, and lays the groundwork for tall wood building construction in urban parts of the state. I will continue to use my seat on the appropriations committee to get this important research and development funded.”

“Oregon is leading the way in developing state-of-the-art timber products that are revolutionizing our nation’s construction industry,” Wyden said. “This funding supports the ongoing research and innovative work Oregon State University is doing to ensure timber products can continue to spark economic growth and create good-paying jobs across Oregon.”

“Oregon State University is at the forefront of research to inform engineering design guidelines for cross-laminated timber structural systems,” said Anthony S. Davis, Acting Dean of the Oregon State University College of Forestry. “This grant award is another example of the excellent research done by scientists affiliated with OSU and the TallWood Design Institute.

CLT Panel Fails During OSU Construction Project

by | Mar 26, 2018 | News

From: Panel World Editors

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.

OSU & D.R. Johnson Work Together To Produce Cross-Laminated Timber

by | Sep 11, 2017 | News

Thanks to a partnership with the Oregon State University College of Forestry, D.R. Johnson Wood Innovations in Riddle, Oregon, recently became the first U.S. certified manufacturer of cross-laminated timber.

Cross-laminated timber (CLT) is a massive structural composite panel product usually consisting of three to nine layers of dimensional timber arranged perpendicular to each other, much like layers of veneer in plywood and can be used as prefabricated wall, floor and roofing elements in residential, public and commercial structures. It is extremely strong and flexible, making it resilient to seismic activity.

Lech Muszyński, assistant professor of wood science and engineering, first saw CLT in production during his 2009 sabbatical in Austria. He says those facilities were unlike anything he had ever seen.

“I decided to visit as many as I could because the diversity was astounding,” Muszyński says. “I learned that you don’t need to be a big operation to make a difference in the market.”

Once back at OSU, Muszyński began making the rounds to industry partners to gauge their interest in constructing CLT test panels. He had little success until a meeting of the college’s Board of Visitors. Valarie Johnson, president of D.R. Johnson Lumber was in the room.
