Coughlin Porter Lundeen is an active proponent of mass timber development, and one of the few engineering firms in the Pacific Northwest with locally built CLT structures. Chris Duvall is a principal at Coughlin Porter Lundeen, which he joined over 20 years ago. He has contributed to various studies concerning the use of CLT and other mass timber materials in lieu of concrete and steel for a variety of building types. He has successfully proposed alternative building materials to local jurisdictions for structural systems not pre-approved by the building code, such as timber-concrete composite floor systems. He continues to push mass timber research and applications forward; participates on the AIA Seattle Mass Timber Committee and is an active member of the American Wood Council, and has several mass timber projects currently underway.
