First mass timber high-rise in U.S. coming to Portland

The Framework Project LLC has tall plans for mass timber in North America. The first undertaking is a 12-story engineered-wood building in Portland, Ore., called Framework Tower.

Before construction can begin on the tower, the mass-timber material must pass several tests. The first was a fire test on a column-beam-floor assembly, made from glue-laminated timber and cross-laminated timber, which the developer has announced demonstrates “for the first time the feasibility of tall mass-timber buildings in the U.S.” Tall mass-timber buildings using GLT and CLT have already been built in Europe, Australia and Canada.
