The Portland Airport

A Story of People, Forests, and a Beautiful Mass Timber Building

In 2020 the Portland International Airport started a five-year transformative remodeling inspired by the lush forests of our region and the potential of mass timber design.

Unique in scale, the project connects 2.2 million board feet to the forests and people that grew the wood. It stands as a North Star for what is possible when sustainable building projects intentionally incorporate positive conservation, community, and equity outcomes. Every piece of wood used in the remodel can be traced back to its forest of origin a love letter to the small families, Pacific Northwest Tribes, and other landowners that contributed to land stewardship and local economies across the region.

Designers & Builders

ZGF Architect's striking designs for the PDX-NEXT remodel have required the Hoffman Skanska Joint Venture and Timberlab to develop innovative solutions to bring it all together.

ZGF ARCHITECTS

ZGF Architects designed and helped orchestrate the wood package for the Portland Airport’s new roof and ceiling, including setting out the vision for a ‘walk in the forest’ as you stand beneath.

HOFFMAN SKANSKA JOINT VENTURE

Hoffman Construction Company teamed up with Skanska USA to create the Hoffman Skanska Joint Venture to construct the Portland International Airport transformative remodel.

TIMBERLAB

Timberlab (formerly known as Swinerton Mass Timber) came onto the project in 2019 in a design-assist role to ensure the design of the mass timber roof structure could be manufactured and procured from regional timber manufacturers sustainably and cost-effectively.

Sourced From Oregon & Washington

Through the stories of three unique wood products: Glulam Roof Beams, Ceiling Lattice, and Oregon White Oak Flooring, we highlight the tribes, family forest owners, and fabricators involved in the remodel of the Portland International Airport.

OREGON WHITE OAK FLOORING

CEILING LATTICE

GLULAM BEAMS

Glulam Beams

The Glulam beams used in the PDX-NEXT remodel represent 1.9 million board feet of wood sourced from well-managed public and private forests in Oregon and Washington. Harvested from forests in the Pacific Northwest, including the Coquille Indian Tribe’s forestland in Southwest Oregon and Yakama Nation’s forestland in Central Washington. The Yakama Nation provided 370,000 board feet, the largest fiber contribution of any of the landowners involved.

The largest beams are 80 feet long and 8 feet thick. Unlike almost any other building in the world, many of the beams in the airport are traceable all the way back to the forests where the fiber was grown. You can point at a specific beam and know exactly what landowner or tribal nation it came from!

The Forests

Harvested from forests in the Pacific Northwest, including the Coquille Indian Tribe’s forestland in Southwest Oregon and Yakama Nation’s forestland in Central Washington.

  • YAKAMA NATION'S FOREST LANDS

    The Yakama Nation provided high-quality Doug-fir lamstock to the PDX airport project.

    The Yakama Nation’s approach to forest management builds on the cultural view of gratitude that natural resources are a gift. Land and resources must be cared for with the understanding that they will be passed to future generations.

    Yakama Forest Products processed Yakama Nation logs and milled them into lamstock. The lamstock was then sent to Eugene, OR, and made into glulam beams by Zip-O-Laminators.

  • COQUILLE TRIBE'S FOREST LANDS

    The Coquille Tribe provided high-quality, Douglas-fir timber for the glulam beams used in the Skylight D roof of the new PDX terminal roof.

    This timber is harvested on an 80-year rotation, meaning their logs grow longer to store more carbon than in a typical commercial forest. The Coquille Tribe prides themselves on the management of their ancestral lands on Oregon’s South Coast.

    Herbert Lumber purchased the Coquille logs and kept them separate from all other logs throughout the supply chain. Zip-O Log Mills milled them into lamstock, and then Zip-O-Laminators processed them into glulam beams.

The Manufacturers & More

Yakama Forest Products, Zip-O-Log Mills & Zip-O-Laminators processed wood into Glulam Beams for the PDX-NEXT remodel.

  • YAKAMA FOREST PRODUCTS

    Yakama Forest Products provided 370,000 BF of wood for the glulam beams. They were the largest fiber contribution of any landowners in the Portland Airport remodel project.

    Guided by cultural ecological knowledge and science, Yakama Forest Products operates on the landscape as critical infrastructure - supporting forest health and landscape resilience to climate change and as an economic tool for the Yakama Nation to provide jobs for the community.

  • ZIP-O-LOG MILLS & ZIP-O-LAMINATORS

    Zip-O-Log Mills milled logs from the Coquille Tribal lands into lamstock and then sent them to Zip-O-Laminators to process into the glulam beams that will span the entire roof of the PDX Airport remodel.

    Zip-O-Laminators created glulam beams using timber from forests across the pacific northwest, including the Coquille Tribe and Yakama Nation. They produce high-quality glulam beams in exceptional sizes, including the exposed wood beams for the PDX Airport remodel, showcasing the magnificence of Pacific Northwest Douglas-Fir.

  • HERBERT LUMBER CO.

    Herbert Lumber Co. in Riddle, Oregon purchased wood from the Coquille Indian Tribe and kept it separate from its other wood sources to ensure its origin could be traced. Zip-O-Log manufactured the wood into glulam beams.

Ceiling Lattice

Harvested from over ten family, Tribal, and community forests across the Pacific Northwest, including family and tribal forest lands. The lattice material used in the new ceiling of the PDX Airport adds some uniquely Pacific Northwest character using beautiful Douglas-fir wood and highlighting the equally touching stories of the local forests and communities who supplied them.

    Manke has been in the Tacoma community for over 50 years and sourced logs from nine different landowners, including the Skokomish Tribe, Cle Ellum forest, and the City of Roslyn, and kept the logs separate to be milled into unique lattice for the Portland Airport's remodel.

 Oregon White Oak Flooring

The flooring in the PDX airport is one-of-a-kind and celebrates all the natural beauty of one of Oregon's most precious resources - trees. The Oregon White Oak used in the new flooring traveled less than 70 miles to get here from Zena Forest, and the relatively small component parts of this flooring greatly reduces waste, and it will be the first of its kind manufactured in the United States. 

For over 30 years, the Deumling family has owned and operated Zena Forest Products and cared for the Zena Forest, proving that forests can be managed for the health of the forest ecosystem while creating jobs and world-class flooring out of native hardwood.

The Forest & Manufacturer

Harvested in the Willamette Valley from Zena Forest and manufactured in Polk County, Oregon by Zena Forest Products.

  • ZENA FOREST

    For over 30 years, the Deumling family has cared for the Zena Forest, the largest remaining swath of forest in Oregon's Willamette Valley. It includes areas of endangered Oak Savannah and Oak Woodland ecosystems and headwaters of the Rickreall, Yamhill, and Spring Valley watersheds.

    The Deumling family has always managed the roughly 1,300-acre forest for complexity out of a conviction that greater diversity means greater resilience. The Zena Forest is a mixed-species, mixed-age forest managed through low-intensity selective harvest.

    Add in the short 70-mile trip from the forest to PDX, and you have an unparalleled story of sustainability and environmental stewardship - from the forest floor to the airport floor.

  • ZENA FOREST PRODUCTS

    Like all Zena Forest Products flooring, the PDX airport's new flooring supports the care and restoration of the Zena Forest. That work includes planting native seedlings and removing invasives without destructive practices like aerial spraying and logging with the health of the whole forest ecosystem in mind. From the tiny Willamette daisy to the biggest fir, all are cherished inhabitants of this lush forest.

    This attention to detail and care for the natural world carries over into the flooring that Zena creates. At every point, they prioritize quality, sustainability, and longevity.

    Their hardwood flooring is built to last over 100 years and endure millions of footsteps.
