A bridge management system is required to ensure the safety of bridges and to optimize the resources available for maintenance and rehabilitation. This paper describes the bridge management practices in Ontario at the project level and outlines the work in progress toward the development of a comprehensive bridge management system at the network level. The visual inspection condition data collected on bridges are supplemented with data from detailed condition surveys that include nondestructive and destructive sampling and testing. The results of those inspections and surveys are assessed to determine appropriate methods and options for rehabilitation. As an economic evaluation is an important step in the decision making process for work that involves major expenditures, the costs for alternative levels of improvements to a bridge are compared to determine the most economical option for the bridge based on a present value analysis and incremental benefit/cost ratio analysis. One benefit of this approach to bridge rehabilitation is significant improvements in the selection of rehabilitation options through detailed life-cycle analysis to determine optimal cost-effective options.
