MILLERSBURG, OR — Timberlab Inc. (Timberlab), a subsidiary of Swinerton Incorporated (Swinerton) and national provider of holistic mass timber systems, has teamed up with Swinerton Builders, Lindgren Development, LEVER Architecture, and other project partners to design and build a 190,000-square-foot cross-laminated timber (CLT) manufacturing facility. This facility will be one of the largest CLT production sites in the United States.
The groundbreaking ceremony, held in Millersburg, Oregon, was marked with a community celebration. Oregon Governor Tina Kotek, representatives from Senator Merkley’s office, state Representative Shelly Boshart Davis, Mayor Scott Cowan, and other government and industry agencies attended the ceremony highlighting Oregon’s commitment to advancing mass timber supply, manufacturing, and construction as a sustainable alternative to traditional construction materials, like concrete and structural steel.
“[This] groundbreaking marks an exciting step forward in the growth of Oregon’s mass timber industry — a revolutionary technology key to our shared goal of building a sustainable, low-carbon future,” Kotek said. “Companies like Timberlab have capitalized on the opportunity to reduce their impact on the natural environment here in Oregon. The introduction of a new facility in Millersburg will expand the supply chain for mass timber, bolstering our regional economy and helping make sure that mass timber is accessible for more construction projects.”
The manufacturing facility will be built with glue-laminated timber (GLT) produced at Timberlab’s other Oregon facilities using locally harvested timber. A Wood Innovations Grant from the USDA Forest Service supports the design of this full-mass timber building. Timberlab has sourced equipment for advanced timber and wood processing. Kallesoe is providing a complete CLT processing line, including an automated feeding system, high-speed cross-cut saws, and a finger-jointing system.

Slated for completion by the end of 2026, the facility, designed by LEVER Architecture and constructed by Swinerton Builders, will produce 7 to 9 million square feet of CLT annually. It is anticipated that 100 direct living wage jobs will be created at full capacity, along with countless indirect jobs. This project will contribute to the region’s economic development and cultivate a skilled workforce for sustainable construction practices.
