DEVELOPMENT OF LIFE-CYCLE ACTIVITY PROFILES IN BRIDGIT BRIDGE MANAGEMENT SYSTEM

The objectives of NCHRP Project 12-28(2)A were to develop a microcomputer-based bridge management system (BMS) that could be implemented by departments of transportation and local bridge authorities as well as satisfy the requirements for bridge management systems mandated in the interim final regulations for Intermodal Surface Transportation Efficiency Act management systems. Phase 2 of the project was completed in 1994 and resulted in the development of the BRIDGIT BMS. The various models used in BRIDGIT to produce life-cycle activity profiles (LCAPs) for each bridge in a network are discussed. In developing repair and functional improvement strategies for any selected group of bridges, it is necessary to identify and compare feasible alternatives. As part of its optimization analysis, BRIDGIT develops different LCAPs for individual bridges and determines the present value of life-cycle costs and benefits for each one. The costs considered include agency costs for the various repair or improvement actions as well as user costs associated with accidents or detours due to load capacity deficiencies, vertical clearance deficiencies, or bridge width deficiencies.
