Life cycle considerations for infrastructure facilities

摘要

This paper presents essential life time considerations for infrastructure facilities. The considerationsare the basis for developing a scientific concept for life time harmonisation. This concept isintroduced and the developed research procedure is explained. The terms infrastructure andinfrastructure facilities are defined. A uniform life cycle model and the different life time types aredescribed. Factors that govern the life times are analysed for the combination in a life timeprognostication model. Examples are presented for road bridges.
