Zur Effizienz von Schieneninfrastrukturbau-vorhaben am Beispiel des Brenner-Basistunnels.Die Zukunft der Schiene mit Milliardeninvestitionen verbaut?

Cost overrun has become a major issue regarding infrastructure projects. Especially in regard to railway infrastructure and the construction of tunnels, building costs are regularly exceeding the original estimates. This article discusses the reasons for this apparently common fact. In addition, reasons for and consequences of misassigned infrastructure investments are pointed out and a concept called "lifetime-based infrastructure controlling" to improve the efficiency of infrastructure projects is outlined. To highlight the importance of this field of research the serious consequences of wrong investments in infrastructure are shown by discussing the current "Brenner-Basistunnel"-project in Austria.
