At the time being the design is mainly focused on the construction phase and the first use, and maintenance and repair are reactive. New and increased demands, e. g. health and environmental aspects are not enough included into these processes. The integrated lifetime engineering methodology concerns the development and use of technical performance parameters to guarantee, that the structures fulfil through the life cycle the requirements arising from human conditions, economy, cultural, social and ecological considerations. It includes: investment planning and decision making, integrated lifetime design, integrated lifetime managemegement, maintenance, repair and rehabilitation (MR&R) planning, reuse, recycling and disposal.
