…Beyond timber management, however, are innovations that promise new uses for timber in construction. Among them is “mass timber” that is used in “tallwood design.” As an example, a credit union in Hillsboro, Ore., is using glulam beams to construct its new five-story, 150,000-square-foot headquarters building. Another building planned for Portland will be 12 stories tall and constructed of cross-laminated timber, called CLT. It will dwarf the seven-story building in Minneapolis, Minn., that is currently the tallest mass timber structure in the nation. To explore the uses and design possibilities of mass timber, the University of Oregon architecture program is combining efforts with Oregon State University’s forestry and engineering programs to create the Tallwood Design Institute.
