Life‐cycle engineering, as being developed at Lehigh University's Engineering Research Center for Advanced Technology for Large Structural Systems (ATLSS), is a comprehensive, systematic methodology which treats each stage in the life of a structure as part of an integrated process. It considers both performance and cost throughout the life of a structure, thus supporting a more balanced view of investment based on construction, operation, renewal, replacement and decommission issues. Consideration of all phases of the life‐cycle supports intelligent and informed decision‐making. Lehigh has an on‐going program of research on methodologies and information systems embodying the life‐cycle engineering approach which is being incorporated into a decision support system for life‐cycle engineering of bridges. The authors describe a prototype model which provides bridge engineers and owners with analytical information to more effectively integrate life‐cycle considerations into engineering decisions concerning bridge decks.
