Abstract [en]

In many countries, bridges are mainly managed using bridge management systems (BMSs). Many BMSs contain some forms 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 to support decisions related to existing bridges. LCC has several useful applications within the bridge entire life, from cradle to grave. This paper introduces the Swedish Bridge and Tunnel Management System (BaTMan). A comprehensive integrated LCC implementation schema will be illustrated, taking into account the bridge investment and management process in Sweden. The basic economic analytical tools as well as other helpful LCC techniques are addressed. A real case study is presented to demonstrate the current improvement of BaTMan practically in the function of whether to repair or to replace a bridge.  Cost records for 1,987 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.
