Infrastructures and Life-Cycle Cost-Benefit Analysis

Design and maintenance of infrastructures using Life-Cycle Cost-Benefit analysis is discussed in this paper with special emphasis on users costs. This is for several infrastructures such as bridges, highways etc. of great importance. Repair or/and failure of infrastructures will usually result in user costs greater than the repair or replacement costs of the infrastructure. For the society (and the users) it is therefore of great importance that maintenance or replacement of an infrastructure is performed in such a way that all costs are minimized - not only the owners cost.
