Finnish bridge life-cycle-cost guideline

Infrastructure owners have recently put efforts to better estimate life cycle costs (LCC) and do life cycle assessment (LCA). In Finland, a design guideline has been recently prepared and taken in use by the Finnish transport agency. This guideline harmonises estimation of LCC at the bridge design or at the bridge renovation stage. LCC is dealt as its wide-meaning, including agency costs, user costs and society’s costs. Indirect costs are dealt by assigning monetary values to non-monetary quantities, including traffic delays, environmental burden and risks. Used methodology is a logical extension of standard quantity take-off and cost estimation of bridges. Present value calculation with multiple discount rates is used. The guideline gives sufficient and comprehensive unit data for preparing LCC-estimates to, e.g., compare various design variants. It also instructs the owner to choose discount rates and weighting factors for the cost types depending on the view-point of the analysis. In the longer view, one is looking possibility to include LCC-efficiency as part of the quality ranking in bids, to promote usage of sustainable structures and detailing. This paper describes the methodology used in the guideline and discusses of the outcome of the case studies.
