About this audio guide
This guide to Climate Pledge Arena in Seattle centers on the 1962 World's Fair roof overhead, designed by Paul Thiry to sit on solid ground forever, and the 2018 decision to keep it floating in place while everything beneath it was demolished. You'll hear the strict tolerance engineers had to hold the roof to while they dug a seventy-foot hole and built a new arena underneath it, and the temporary steel supports and constant sensor checks that made it possible. It's a guide about an engineering problem nobody had solved quite this way before.
