Applications of life-cycle costing for bridges and integration with bridge management systems
(English)In: Civil Engineering and ArchitectureArticle in journal (Refereed) Accepted
Many countries are using bridge management systems(BMSs) as the main toll for the effective management of their bridges. Althoughmany BMSs contain some forms of life-cycle cost analysis (LCCA), the use of LCCAin bridge engineering is scarce and LCCA has mainly been applied to supportdecisions related to existing bridges. This paper discuss the need of a BMSwith an integrated LCCA tool that can assist decision makers at all levels andwithin all phases in selecting the most cost-effective solution from an arrayof applicable alternatives. The paper introduces the Swedish Bridge and TunnelManagement System (BaTMan). A comprehensive LCCA implementation scheme will beillustrated, taking into account the bridge investment and management processin Sweden. The basic LCCA analysis tools as well as other helpful techniquesare addressed. A real case study is presented to demonstrate the recentimprovement of BaTMan particularly in the function of specifying the most-costeffective bridge repair strategy. The bridge user cost is included in the LCCA.The parameters that can influence the final decision are addressed andsensitivity analyses to study their impacts are performed.
