The prevailing goal and trend in all areas of mechanical industry as well as in building and civil engineering is Lifetime Engineering (also called ‘Life Cycle Engineering’). The integrated lifetime engineering methodology aims at regulating optimisation and guaranteeing the life cycle requirements with technical performance parameters. With the aid of lifetime engineering, we can thus control and optimise the human conditions (functionality, safety, health and comfort), the monetary (financial) economy and the economy of nature (ecology), also taking into account the cultural and social needs (Figure 2.1). 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, economic, cultural and ecological considerations.
