M-B served as a subconsultant to CALTROP in the provision of professional project risk management services in support of the $6.4B Toll Bridge Seismic Retrofit Program (TBSRP). The new San Francisco-Oakland Bay Bridge, the most expensive public works project in California history and world’s widest bridge, required the demolition of the existing bridge and involved the construction of a new transition structure, main span, skyway, approach, and touchdown. The final design included a stunning single-towered self-anchored suspension span starting at Yerba Buena Island, leading to a long-inclined viaduct to the Oakland touchdown. The roadway’s custom lighting uses 48,000 high-performance LEDs grouped in 1521 fixtures, most of which are mounted on 273 poles. A major challenge was coordinating with the Bay Area Toll Authority, the Association of Bay Area Governments, and CALTRANS as well as scheduling bridge shutdowns to accommodate the work.

Caltrans enlisted CALTROP, which tapped M-B for assistance given its experience and professional credibility. M-B’s role was to help perform the following tasks: Update the risk management plan and risk register that identifies risks, assess their probability and their impact on project scope, cost, schedule, and quality, as well as maintain and update a risk management database. M-B assisted in the preparation and delivery of quarterly risk management reports and facilitated the incorporation of risk management data in the Program’s Quarterly Report to the State Legislature. CALTROP developed a Risk Management Manual for CALTRANS which then was adopted for all of its projects.
