The Minnesota Vikings’ new home, US Bank Stadium in Minneapolis, is recognized for its lightweight long-span roof. To achieve this, the roof was designed to shed snow but with its elevation at approximately 200 ft, the roof's snow could not be allowed to drop onto the pavement below. A snow catchment system was envisioned with troughs located just below the roof's perimeter. With the troughs at height, it was not practical to provide the necessary concrete as cast-in-place. Geiger Engineers developed a composite tilt-up assembly for the perimeter walls of the snow catchment system. Lateral design loads were 450 psf snow and 40 psf wind. Wall panels were prefabricated at ground level and lifted into place using the construction site's tower cranes.
