Network-Level Bridge Life-Cycle Management System

Abstract

In existing bridge management systems, the information on one stage in the life cycle of a bridge is not efficiently used in other stages, which results in much waste in time and effort. In this paper, a new type of bridge life-cycle management system is developed to overcome this problem. The system integrates geographic information, design data, inspection and maintenance data, earthquake data, and image data in a user-friendly environment. These improvements make it possible to use the system during the entire bridge life cycle, from the planning stage to the demolition stage, as discussed here. Several applications of this system are discussed, which include location selection, condition assessment, maintenance plan optimization, and spatial retrieval.
