Before construction began on the South Terminal Redevelopment Project (STRP) at Denver International Airport, tension cables anchoring the Birdair-built “mountain range” membrane roof system needed to be moved to make room for the expansion. Birdair’s project role involved designing and building two temporary shoring towers to carry the vertical and horizontal roof loads. The steel towers extend 30 feet below grade and rise 70 feet above ground. Once the shoring towers were erected, Birdair transferred the 215,000-pound roof load and removed eight roof anchors that comprise the south end roof “eyebrow,” which is currently blocking excavation for new construction.
