Bay Bridge YBI Viaduct Bridge Replacement, Oakland, CA:

ADKO Engineering is providing analysis and design of the bay bridge Yerba Buena Island Viaduct five span replacement project, for construction loads and unusually loads. The bridge will be constructed on false work system adjacent to the existing bay bridge and skidded in place once the five spans are demolished. The falsework needed to be analyzed for various loading conditions to determine the effective bracing system that can withstand the high wind loads and minimize the lateral displacements while providing an efficient design to meet the tight construction deadlines. Different ground elevations and construction staging had to be considered to overcome specific challenges imposed by unique sight conditions.
