Tallest Mass-Timber Building in U.S. Gets Approval for Construction

The Framework Project has received approval for a building permit, allowing construction to begin on the largest tall wooden structure in the United States. Portland's LEVER architecture designed the 145-foot tower, which Ted Wheeler, Mayor of Portland, called "a true technological and entrepreneurial achievement."

The mixed-use building will include offices, street retail stores and sixty units of affordable housing. A collaboration between developer project ^, Home Forward, Albina Community Bank and Beneficial State Bank, aims to promote economic opportunities through sustainable building practices. Governor Kate Brown praised the project to demonstrate how wood construction can create jobs in rural economies. "The forests of Oregon are a proven and real resource that can still be the key to economic stability for rural Oregon," she said in a statement.

The 12-story tower was one of two projects that divided the price of the $ 3 million Tall Wood Building, sponsored by the US Department of Agriculture, the Softwood Lumber Council And the Binational Softwood Lumber Council. The building permit was approved following a series of rigorous tests on fire, acoustics and structure that validated the resilient structural design meets fire safety standards.

Built with laminated laminated wood and glue laminate, Framework also includes the "Tilting Wall" - an innovative core system of CLT vertical panels and post tension cables that allows the building to withstand an earthquake with a minimum of damage.
