The GRE is a large structure designed to minimize noise from engine run-ups that are conducted as part of regular aircraft maintenance work. It will be next to the South Terminal where the majority of airlines who perform engine run-ups at YVR are located. This will stop aircraft having to travel to the far end of Sea Island to perform engine run-ups, saving airlines valuable time and fuel and providing environmental benefits to the region.
This is no small enclosure. It's actually a giant three-walled, open-roofed structure, roughly the size of a football field and up five-stories tall on one side. And more than 3,800 cubic meters of concrete will be used to build the enclosure and adjoining apron.
