Construction at the new headquarters for the College of Forestry at Oregon State University is making great headway. We're particularly excited to see the acetylated alder siding going up. Accetylation of wood is a process by which the wood is made more durable and dimensionally stable through the impregnation of the cell structure with what is in effect...vinegar!

The mass timber structure of the new Peavy Hall, a feature building of the Oregon Forest Science Complex, has been taking shape since early December 2017 as glulam and cross-laminated timber from DR Johnson Wood Innovations arrives onsite and is erected into place. Some of the first wood elements to be seen onsite were the rocking shear walls that will ensure the building is resilient after seismic events. This is the first appearance of this technology (developed in New Zealand) on a US construction site.
