Many countries use bridge management systems (BMSs), and many of these systems involve some form of life-cycle cost (LCC) analysis. Use of LCC analysis in bridge engineering is rare, however; the technique has been applied primarily in the operation phase to support decisions about bridges that already exist. Yet LCC analysis can be applied across the life of a bridge. This paper introduces the Swedish Bridge and Tunnel Management System (BaTMan). A comprehensive, integrated LCC implementation scheme takes into account the bridge investment and management processes in Sweden. The basic economic analytical tools as well as other helpful LCC analysis techniques are described. A case study demonstrates improvements in BaTMan as a factor in the decision whether to repair or to replace a bridge. Cost records for 1,987 bridges were used as input data in the case study. On the basis of the same records, the average real and anticipated initial costs of various bridge types in Sweden are presented schematically.
