A massive spanning 9 acres now crowns , the result of groundbreaking construction techniques that allowed the busy transportation hub to remain fully operational throughout its major renovation.

The Hoffman-Skanska joint venture and its teams completed the installation using an unprecedented strategy that prevented disruption to the 50,000 daily passengers while meeting the Port of Portland’s stringent seismic resiliency requirements.

Serving millions of travelers each year, PDX could not afford the widespread closures that on-site roof construction would have required. To solve this challenge, construction teams built the entire roof structure off-site in 20 massive sections called “cassettes,” each containing approximately 120 individual components including skylights, insulation and mechanical systems. The largest cassette measured 220 feet by 110 feet. The construction required a 20-acre staging area near the airport’s fire department headquarters, featuring a reinforced concrete pad engineered to support the weight of the roof modules during assembly.

In a first-of-its-kind sustainability initiative for a project of this scale, all timber was sourced from 13 sustainably managed forests in Oregon and Washington. The project team established a comprehensive tracking system to ensure wood could be traced from “forest to frame.”

Timberlab was instrumental in advancing wood innovation at PDX, supporting the development of the signature 400,000-squaer-foot roof. Timberlab and Hoffman-Skanska selected local firms such as Zip-O and Freres Lumber to fabricate key structural components.

Special consideration was given to , with the roof and curtain wall system designed to move up to 24 inches in any direction during an earthquake. This movement is made possible by seismic base isolation bearings that support the roof structure.

In another innovative move, workers repurposed a connector between concourses that was slated for demolition, transforming it into a pedestrian bridge bypass. This creative reuse prevented 3.4 million pounds of material from entering landfills.

The project is certified.

Minority- and women-owned businesses’ participation on the overall project ranged between 22 percent and 25 percent.

Subcontractor Western Partitions played a key role on the project. Its scope – totaling $19.5 million and involving 400,000 square feet of space – included exterior and interior metal framed walls, interior soffits and ceilings, insulation, drywall, taping, stadium seating framing, and mass plywood panels atop the concessions spaces and airline offices. The company spent approximately 20 percent of its contract on partnerships with MWESB subcontractors and suppliers.
