Title:
Abstract:	Brückenbauwerke wurden in den vergangenen Jahrzehnten viel zu oft als reine Zweckbauten angesehen und ihre kulturelle Bedeutung sowie die Wechselwirkung mit der Umwelt vernachlässigt. Im Rahmen der aktuellen Ansätze einer ganzheitlichen Bewertung von Baumaßnahmen rücken jetzt viele über den reinen Herstellungspreis hinausgehende Bewertungskriterien in den Vordergrund. Diese sind aber insbesondere für Infrastrukturbauwerke noch nicht vollständig entwickelt. So existiert hier bisher kein ganzheitliches, in sich abgestimmtes System, das ähnlich wie im Hochbau eine Nachhaltigkeitsbewertung ermöglicht. Der vorliegende Beitrag stellt den aktuellen Stand der Nachhaltigkeitsdiskussion im Brückenbau dar und zeigt anhand zweier Anwendungsbeispiele bestehende Probleme und Defizite auf. Darüber hinaus werden zukünftig zu lösende Aufgaben sowie zu entwickelnde Bewertungsansätze diskutiert. Sustainability assessment of bridge constructions. In the past, building structures were often regarded as functional buildings; their cultural significance as well as the interaction with the surrounding environment were frequently neglected. Within the scope of a growing demand for a holistic assessment of building activities, many evaluation criteria going beyond the pure manufacturing cost come to the fore. They are, however, not completely developed for infrastructure buildings. Up to now, no holistic, coordinated system is available facilitating a sustainability assessment similar to building construction. This article presents the current state of the sustainability assessment in bridge construction and shows existing problems and deficits by means of two application examples. In addition, problems to be solved in the future as well as approaches of assessment to be developed are discussed.
