Plaza Bridge at Marine Way, Irvine, CA

As part of a design-build contract for a new corporate headquarters for Broadcom, Biggs Cardosa was lead designer for two structures over Marine Way that provide pedestrian and vehicular connectivity between the buildings. The multi-disciplinary design team included architects, landscape architects, electrical engineers and lighting designers, waterproofing consultants, fire protection analysts and civil engineers. Plaza Bridge is a 400-foot wide, three-span bridge that covers Marine Way and supports a park with pedestrian paths that bring together the two halves of the campus. The bridge super structure was designed for unusually high applied loads resulting from the soil and trees of the park above. The design incorporated a waterproof membrane on the bridge deck and drainage features to control irrigation water.
