Through the rise of mass timber, and especially cross-laminated timber (CLT) panels, one of the world’s oldest building materials is being reimagined as a viable, sustainable alternative to concrete and steel. Studies and reports have proven the safety and reliability of structural CLT, and innovative wood designs are going taller, spanning farther, and finishing faster. In the Pacific Northwest, a variety of CLT buildings are helping to spur building code changes, improve wood-based economies, and demonstrate the untapped potential of this versatile material.

This panel of professionals from across the design and construction industry will provide current insights into the world of structural CLT, which is rapidly evolving and maturing. By sharing lessons learned from their recent experiences with designing, engineering, and constructing with CLT panels, the panel will explore design, code and construction implications. Their real-world, hands-on experience with buildings constructed in the last year, currently in construction or about to start will draw architects, engineers and contractors who want to understand how to push the CLT envelope even further.

Learning Objectives:

  • Identify challenges and opportunities with using wood as both structure and finish to reduce material use.
  • Evaluate CLT building systems in order to choose the most appropriate system and materials for specific project needs.
  • Understand the effects of CLT supply chain, lead time, and installation on project schedules and budgets
  • Understand the onsite construction benefits of CLT

Joseph Mayo, Assoc. AIA, LEED AP BD+C | Mahlum Architects
Joseph Mayo is author of the book Solid Wood: Mass Timber Architecture, Technology and Design. He has worked on a variety of building types, ranging from schools, student housing, university buildings and hospitals. Working with a City of Seattle Department of Planning and Development (DPD) Advisory Committee, Joseph led an investigation into the use of wood in applications that go beyond current building codes. He has also been a jury member for wood design awards, served on several local and national AIA Committees, co-authored a research paper exploring the economic viability of tall wood buildings, and has assisted in teaching mass timber courses and served on architecture critiques at universities throughout the Pacific Northwest. He advised Mahlum’s team on their design for the new Richard Woodcock Center for Education at Western Oregon University, the first installation of Oregon-made structural CLT in the country. The Woodcock Center is under construction and scheduled to open September 2016.

Andy Dykeman, Project Manager | Lease Crutcher Lewis
An authority in sustainable construction, Andrew Dykeman is a senior project manager at Lease Crutcher Lewis. He is currently wrapping up the Oregon Zoo Elephant Lands project, which includes the first installation of CLT in Oregon. Lease Crutcher Lewis has also completed CLT installations in Seattle, WA at the Shoreline Medical project. In 2014, Andrew was part of an Oregon Structural Specialty Code – Technical Workgroup, which reviewed and commented to the Building Code Structures Board on the mid-cycle code adoption of the State Wide Alternative Method addressing the use of CLT, to align with the 2015 IBC. Andrew is an AGC Columbia Chapter board member, and is the past chair of the AGC Construction Leadership Council, and current vice-chair of the Construction Management Education Council. He has appeared as a guest lecturer at Oregon State University, the University of Oregon, Portland State University, and for Lane Community College. Andrew has also presented nationally, at the 2010 Greenbuild forum in Chicago.

Eric McConnell, PE | KPFF Structural Engineers
Dedicated to research and implementation of best seismic design practices, Eric remains at the forefront of the emerging mass timber industry standards. Having been largely shaped by his experience working in KPFF’s San Francisco office and two years working for a New Zealand firm in Post-Earthquake Christchurch, Eric is well positioned to bring knowledge of the latest techniques of resilient design to his projects. With a passion for structural detailing, Eric excels in the coordination of structural elements with other design disciplines, along with the design and implementation of innovative lateral force resisting systems. Eric used CLT as a structural element for two recent projects: The recently completed Rocky Mountain Institute Innovation Center in Basalt Colorado by ZGF Architects, which uses a unique two-way CLT floor system with integrated MEP systems. And the 12-story Framework project in NW Portland, by Lever Architecture, which is one of the two winners of the U.S.D.A. Tall Wood Building Competition. The project will be constructed almost entirely of mass timber elements, including a resilient / low damage CLT core design.

Valerie A. Johnson, President | D.R. Johnson Lumber Company
Valerie Johnson is the President and a second generation partner of the family-owned D.R. Johnson Lumber Company and affiliates. Valerie has worked for forty years in and for the forest products industry. As President for the past ten years, she has worked collaboratively with her executive team to forge a dynamic strategy for the future of the company, including building and operating the first manufacturing plant of certified structural CLTs in the United States. Currently, Valerie serves on the Boards of Directors for the American Forest Resources Council (AFRC), the Oregon Forest & Industry Council (OFIC), and the Western Resources Legal Center (WRLC), which is the nation’s first legal education program training law students to advocate for natural resource industries and is affiliated with Lewis and Clark Law School.

John Redfield, Chief Operating Officer
John has worked in the timber industry for thirty-five years, accumulating expertise in all aspects of lumber manufacturing, most recently for sixteen years at D. R. Johnson and affiliated companies in eastern and western Oregon. Since 2008, John has also been the COO of Riddle Laminators/D.R. Johnson Wood Innovations, and has been the key executive of the company to lead the team in designing, building and operating the new CLT facility. John is a WCLIB board member and participates in many timber-related organizations. John traveled to Europe twice in the past year to research and learn about the well-developed CLT design and production process there.
