This paper reviews the range of techniques available to show the systems method for bridge maintenance management, which maximises the use of condition data collected, provides an optimal technique for reporting performance target compliance. Although condition measures obtained from inspection programmes are considered relatively imprecise robustness and hence confidence in the output can be improved by using non destructive testing and evaluation. Reviewing a case study of 40 bridges has shown that high level performance measures based on bridge condition and component condition state distributions and the systems method for bridge maintenance management allows the cost effectiveness and efficacy of bridge investment programmes to be evaluated and reported. The paper highlights the need for the RCA to have a vision on the monitoring and reporting requirements so that bridge management systems and practices are set up accordingly. Unbiased condition measures are required to reinforce early intervention for proactive preventive maintenance. (a) For the covering entry of this conference, please see ITRD abstract no. 0612AR242E.
