Popis: The reason why sustainability criteria at the time have hardly any influence on the choice of a bridge design is that it is an extensive procedure which takes too much time to be done during the planning phase and so mostly the cheapest building price is thedecisivefactor. For easily making decisions with a holistic view, it is important to know the key factors that really have a noteworthy influence on the sustainability, considering the whole life cycle and not only the construction phase. Therefore, sustainability assessment is carried out on several bridges with similar boundary conditions. Itwasfound thatone of themost important parametersis a correctpicture of futurescenariosandthat one structureshould alwaysbeconsideredonlyas partof an entireconstruction stage.
