In the increasing need for larger and more complicated projects, a valuable amount of data is available in lessons learned from prior projects to support the execution of existing and planned projects. The 1989 Loma Prieta earthquake initiated the California Department of Transportation replacement or retrofitting of more than 2,000 bridges in the state. One of those bridges was the San Francisco Bay Bridge. The western span, Golden Gate portion, of the bridge was seismically upgraded while the eastern span was deemed in need of replacement. The project experienced both a 246% cost overrun and 63% schedule overrun in which the state passed Assembly Bill 144 establishing additional funding, instating a governing body, and provided operating requirements for the project. The project provided a lessons learned identifying areas of positive performance and recovery from poor activities.
