Abstract [en]

Bridge investment and management decisions are multi-alternative-oriented. In many countries, bridges are mainly managed by a certain bridge management system (BMS). Many BMSs contain some form of life-cycle costing (LCC). However, the use of LCC in bridge engineering is scarce, and LCC has mainly been applied within the bridge operation phase. LCC has several useful applications within the bridge entire life, from cradle to grave. This paper demonstrates the bridge investment and management process in Sweden and simultaneously addresses the possible LCC applications. The paper discusses the need of a BMS with an integrated comprehensive LCC tool that can assist decision makers at all levels and within all phases in specifying the most cost-effective alternative taking into account all affected parameters. The basic economic analytical tools as well as new helpful LCC techniques are presented. The paper introduces the Swedish Bridge and Tunnel Management System (BaTMan). A real case study is presented to demonstrate how the decision process in BaTMan can be improved when deciding whether to repair or to replace a bridge. The analysis in this case study highlights the major issues to be considered in developing BaTMan in that particular function. Cost records for 2,560 bridges are used as input data in the presented case study. Considering the same records, the average real and anticipated initial costs of different bridge types in Sweden will be schematically presented.

The project presented in this paper is sponsored by the Swedish Transport Administration (Trafikverket). The project aims at enhancing the bridge investment and management decisions by developing and expanding the use of LCC in BaTMan.
