The current generation of advanced bridge management systems (BMS) assist the bridge manager/ owner in managing inventory and inspection information, and typically include some form of condition performance measure, as well as an overall sufficiency rating, and perhaps other management indices. These systems include the functionality to recommend prioritized work programs and budgets for the network or subsets of the network. Most commonly, lifecycle cost analysis is used to determine the benefits of doing the work and the ratio of benefit to cost (B/C) is used as the main ranking method. A shortcoming of these powerful systems is the lack of explicit consideration of risk in the prioritization of recommended work. Condition indices are only a measure the relative condition of structures and cannot be used reliably to prioritise projects; structures can have the same condition index but very different criticality or urgency. Recent bridge collapses have reminded us that criticality and urgency of recommendations should consider element function and behaviour as well as condition severity and extent. A new approach has been developed which adds risk analysis to the traditional B/C analysis and project prioritising process. When used in an advanced BMS, the results of the prioritization process are improved and more often meet the expectations of the bridge engineer/ manager.
