Tallest GRE In North America Constructed in Portland

After a worldwide search, Port of Portland engineers and operations staff selected BDI to design a ground run-up enclosure for Portland International Airport (PDX). To find the most advanced and low-risk GRE design, PDX staff traveled to engine run-up facilities throughout the world, including airports in Germany and England.
“The GRE from Blast Deflectors ended a five-year ban on nighttime run-up tests,” says Glenn Woodman, Port of Portland Airside Operation Planner. Prior to the installation of the GRE, noise complaints had triggered a state-mandated ban on nighttime ground run-ups at PDX. Because the GRE offered such a significant noise level reduction, the ban was lifted and all aircraft were required to use the GRE for ground run-ups.
