The new two-story, 27,090-square-foot office building serves as Harder Mechanical’s new headquarters. It utilizes a mass timber frame, glulam columns, and cross-laminated timber (CLT) floor panels—all of which was fabricated by Timberlab and installed after being locally manufactured in Oregon.

The use of mass timber provides for a much lighter building versus traditional structural steel. As a result, the glulam beams and columns utilize shallow concrete footings. Swinerton assisted the design team in reconsidering mass timber (CLT) for the frame to deliver cost and schedule savings.

Skylights bring light deep into the center of the building, providing for an open space work environment that feels airy and welcoming. Large windows show off the timber’s warm tones, particularly when lit up at night. The exposed mechanical system was self-installed by Harder Mechanical themselves. It is clearly visible in the exposed ceilings, as they wanted to showcase their industry-leading line of work.
