A structure database and its application: Maintenance Information Management System and Bridge Management System of Hanshin Expressway

Abstract

For efficient management of various structures in a large highway network, systematic handling of data is essential since its volume has swollen over the years and it takes different forms such as diagrams and photos. The Maintenance Information Management System established by Hanshin Expressway Public Corporation (HEPC) is a computerized database and a processing and reference system of all bridge structure elements. As it is a comprehensive application, HEPC is also developing its own version of a bridge management system, which helps to plan annual budget allotments and work prioritization using the life cycle cost minimization rule. Both systems are tools to support a rational decision-making process of maintenance/repair programmes under the recent curtailed financial situation.
