Clay Creative, a mixed-use project in the heart of Portland’s Central Eastside Industrial District, is the result of a design approach in tune with both the neighborhood’s historical context and its ongoing evolution into a creative area. Integral to the building’s design, and appeal, is its heavy timber structural system. Five-stories of Type IIIA post-and-beam construction sit over a one-story, Type IA deck. The structure consists of dimension wood floor framing with plywood sheathing over vertical nail-laminated timber (NLT) decking; the decking spans between glulam beams and girders supported by glulam columns. Designers used an exterior steel moment frame to keep the core area open. Inside, they used a typical structural grid of 25x30 feet, with mid-bay beams in the long spans and girders in the short spans. Concealed steel bearing and knife plate connections attach to the exposed glulam beams with countersunk bolts for added fire protection. Sustainable design was a goal, so wood for the 90,000-sf building was locally sourced.

Review a business case study for this project (page 21). Business case studies are prepared by WoodWorks and Conrad Investment Management to address the performance of US properties constructed with mass timber structural systems.  The goal is to substantively communicate the business case of mass timber buildings in a relevant and relatable fashion across a series of product sub-types, and new studies are added to the document as they are released.
