Life-Cycle Costing Integration with Bridge Management Systems

The implementation of a bridge design proposal, as well as an individual bridge structural member, generally has several alternatives to choose from. The alternatives may provide the same required function. However, each of them may has different specifications concerning its initial costs, anticipated service life, required future repairs and impacts on traffic flow during repair works. Moreover, the cost categories associated with the various alternatives are incurred at varying points in time. Life-cycle costing (LCC) is an appropriate tool that can be used to specify the most cost-effective alternative taking into account all parameters. Most of the reported LCC applications for bridges were far from ideal and were content with deterministic estimates of life cycle cost instead of using sensitivity analysis. This paper briefly describes the various bridge investment phases and demonstrates the possible applications of LCC regarding them. The economic analysis tools that LCC is based on are presented. A detailed practical example to illustrate the LCC application for bridges during design and construction phases is also presented, taking into account the bridge user costs. The analysis results highlight the great feasibility and possibility of LCC implementations for bridges.
