Redmond Airport Expansion

The Redmond Municipal Airport terminal expansion is the first addition to Central Oregon's primary airport since 2008. The $180 million project combines selective demolition, addition, and renovation of the existing building. Over 80,000 sf is added at one end, roughly doubling terminal capacity, with a new second-level concourse, seven boarding bridges, larger holdrooms, improved accessibility, and expanded concessions. The architecture responds to the surrounding landscape of the Oregon high desert. Glazing runs floor to ceiling on the new facade, opening the interior to the Cascade peaks and volcanic rock formations beyond, while vertical fins on the exterior, arranged in a Cascade mountain motif temper direct sun. Timber left exposed overhead grounds the space against that expanse of glass.

The structure utilizes a rectangular shed roof, built from 2x10 DowelLam acoustic dowel laminated timber (ADLT) and standard DLT panels spanning 30 feet over glulam beams in a typical two-span layout, totaling approximately 33,700 sf. Unlike other mass timber products, DLT is doweled with hardwood rather than glued, eliminating adhesives from the panel. In the ADLT panels, slots are cut and acoustic material is inserted inside, allowing the wood to remain fully exposed while achieving up to a 0.70 NRC, absorbing sound in the high-volume holdrooms without drop ceilings. One-foot chases run between the panels, letting MEP utilities recess into the exposed ceiling rather than surface-mount and disrupt the visual exposure of the timber.
