Mass Timber's Heartwood Tour

Come tour and learn about the tallest mass timber building in Washington State – the Heartwood project currently under construction in the heart of Capitol Hill. This event will include a construction site tour followed by a presentation and discussion with the project team.

The tour and discussion will be led by atelierjones (architect), Swinerton (general contractor), Timberlab (mass timber specialist and installer), and DCI Engineers (structural engineer). As the Owner and Developer, Community Roots Housing, Skipstone and Dali Development assembled and led this fully integrated and visionary project team. Discussion will center around the design of 67,000 SF workforce housing project, as well as building code implications, team coordination, detailing, manufacturing, prefabrication, and construction.

The project is designed with a mass timber structural system, from locally sourced, sustainably harvested timber. The groundbreaking eight-story, 126-unit project will utilize the new Type IVC mass timber building codes, which Susan Jones helped to craft as part of the ICC Tall Wood Building Committee from 2016-2019. The project development was also supported by a generous USFS/Wood Innovation Grant from the United States Department of Agriculture.
