UPDATE: Adidas just informed us that, although we are still allowed to visit their campus, we are no longer allowed to tour inside their mass timber buildings as planned. They cited concerns with COVID-19 as a primary reason. Instead, adidas will show some presentations and take attendees on a tour of the exterior of the buildings. Lunch will also be served on campus.

Following a national design competition, adidas selected the team of LEVER Architecture, Studio O+A, and GGN to realize a major expansion of their North American Headquarters. The target LEED v4 Gold project enhances adidas’ Portland, Oregon, campus with a new arrival sequence and two signature buildings. The overall material palette for both buildings is raw, authentic, and appropriate to the task: exposed concrete and wood, as well as metal panels that are woven across the façade. Leveraging the firm’s expertise with timber innovation, the design for the Gold Building deploys a unique hybrid structural system made from pre-cast concrete columns and girders with glulam beams and cross-laminated timber (CLT) panels. The Performance Zone Building’s all mass timber design includes glulam columns and beams with CLT panels. Located over an existing parking garage, the design takes advantage of the lightness of wood to create a larger structure. Mass timber’s warm character, technical innovation, and connection to the regional forestry culture make it an ideal material for a cutting-edge brand with roots in the Northwest.

Be one of the first to see the new mass timber roof for the Portland International Airport main terminal expansion and renovation. Part of PDX NEXT — a $2 billion investment to transform the airport — the roof will be the grand highlight of the new main terminal, slated for completion in 2025.

Featuring 3.3 million board feet of regionally- and sustainably-sourced Douglas fir, the 9-acre, seismically-isolated curved timber roof is awe-inspiring. Constructed offsite adjacent to the PDX airfield, the roof will be installed over the existing terminal over several nights in 2022. The roof incorporates over 2,000 glulam beams, including 272 single-span glulams reaching a massive 80 feet in length. In addition, 182 beams have arches reaching nearly 16 feet high, a size never before done with glulam of this shape as a single piece. In addition, more than a thousand 2-inch mass plywood panels are used extensively across the roof to make its intricate, curved design possible. Fastened to the underside of the glulam beams are more than 30,000 custom cut pieces of 3×6 lattice.

D) First CLT Subdivision in the U.S.

Location: Portland, Oregon
Scale: 50,000 sf (via 14 homes)
Completion: 2022

Tour attendees will get an insider’s look at the nation’s first cross-laminated timber (CLT) subdivision, just finishing construction in Portland’s quintessential “Northwest” neighborhood. Developer Noel Johnson has translated lessons learned from his mass timber office projects into a family-focused housing project that delivers verifiable ESG features amid a walkable, urban setting. Architect of Record Tuan Luu (who Noel collaborated with on Portland’s 120 Clay mass timber office project) utilized the IRC code path for these fee-simple (detached) homes designed in a traditional row home architectural pattern language.

The result: an impressive 40 homes per acre density with all the function and charming form desired by today’s busy families. Technical approaches include the use of DR Johnson Wood Innovations’ five-ply CLT panels—made from fire-salvaged timber—that sit upon traditional pre-fab’d offsite wall panels. This allows for fast erection to get the MEPS trades going and a “core & shell” structure to better enable future homebuyer customizations. The project’s goal is to demonstrate a replicable, scalable way to use CLT as our industry responds to what Millennial homeowners want.

Ponderosa Pine CLT: Performance, Standards and Modular Design

Ponderosa pine has historically dominated the landscape of the east Cascades, Klamath, and Blue Mountains. These ecoregions face new management challenges as a result of climate change and a history of fire suppression, resulting in denser stands and higher fuel loads under increasing drought conditions. Dr. Mariapaola Riggio and Dr. Lech Muszynski will showcase and discuss research efforts focused on utilizing ponderosa pine for CLT and validating its performance, from the PRG320 standard through modular construction design applications.


While wood is a great material for resonating tones in musical instruments, it comes with its own challenges when designing for acoustic separation in multifamily homes, hospitals, and other building types that require peace and quiet. Join Dr. Mark Fretz of the University of Oregon’s Institute for Health in the Built Environment (IHBE) to learn about acoustics in timber structures, and to see a live demo of acoustic testing devices used to assess mass timber structures acoustic performance.

Sponsored by Skanska

Please join us for an exciting multi-media tour of the massive new roof structure at the Portland International Airport in Portland, Oregon, USA. This virtual visit to a once-in-a-career project will give you an in-depth look at the planning, logistics, and craftsmanship that are going into the over 2 million board foot mass timber and steel roof over the expanded terminal. Since the roof is being fully prefabricated on the ground (membrane, skylights, etc) prior to moving it into place, this tour will be a unique opportunity to see the near final product close up. The tour will also share progress photos and behind the scenes details of the more than four years of planning that have prepared the team for the big move later this summer. The tour will culminate in sequence showing the plan for moving these massive sections across the runways and into place above a fully operational airport.


Siemens Campus Erlangen in Germany

  Virtual Tour

May 12, 2022

Sponsored by CREE Buildings

Always wanted to visit a CREE building but never had the chance?

Join us virtually as we experience the largest building project currently underway in Germany: the Siemens Campus Erlangen.

This is an ambitious project in every respect — when finished it will cover an area equivalent to an incredible 75 soccer fields. What makes it truly remarkable is that the new central reception building and four office buildings (with a total area of around 860,000 sq. ft 80,000 m2) are being built using CREE Buildings’ prefabricated, regenerative timber-hybrid system, with the whole project supported by model-based work processes (BIM — Building Information Modelling). Thanks to innovative prefabrication processes, the CREE system significantly shortens the time needed to erect the main structure, while simultaneously reducing the dust, noise, and waste generated on site compared to conventional concrete construction projects.

These new campus buildings will serve as a testament to Siemens’ ecologically responsible mindset, as well as showcasing the possibility of saving time and resources through smarter building practices.

Michael Kamenik, lead architect and global partner coordinator at CREE Buildings, will be your tour guide. He will show you the attractive campus setting with its state-of-the-art office infrastructure and buildings, punctuated with valuable technical insights. Accompanied by two experts, you will gain insights into the challenges and lessons learned during planning and construction. You’ll also get insights into the prefabrication and assembly process, as well as the main idea and decisions behind this exceptional project.
