Soon, the last of these massive timber modules will make their way across the airfield to finish the roof expansion. To avoid travel disruptions to the public, the mass timber roof was built a half-mile away from the main terminal, then disassembled in 100×300 modules and assembled above the existing roof.

Crafted from approximately 3.3 million board feet of regionally sourced Douglas Fir, the structure features over 400 glulam arches, each spanning 80 feet, creating an undulating form reminiscent of the Pacific Northwest’s natural landscapes. Nearly all the locally sourced lattice was fabricated by Timberlab at our Portland, Oregon, operation. If you’re attending this year’s International Mass Timber Conference, Timberlab highly recommends spending extra time at the airport to decompress and enjoy its natural beauty.
