Cost and schedule development for Stuttgart 21 and the Wendlingen – Ulm new construction line
On January 26, 2018, the Supervisory Board of DB AG deliberated the schedule and cost situation for the Stuttgart 21 project. The cost forecast was increased to a total value of about € 7.7 billion. To take into account unanticipated events, further funds of about € 0.5 billion have been earmarked, meaning that the overall funding framework has increased to € 8.2 billion. In addition to increases in construction prices, the increase in costs results in particular from significantly more elaborate procedures for tunneling in the anhydrite rock, more extensive approval processes as a result of species protection and the postponement of commissioning to 2025, among other things.
The cost and schedule planning for the Wendlingen–Ulm new construction line was also deliberated. The cost forecast was increased to € 3.7 billion and the completion date postponed to 2022. The cost increase is mainly down to greater geological risks as well as additional capital expenditures in the modernization of Ulm Central Station. The one-year delay results from more elaborate plan revision procedures for species protection in the Alpine Foreland.
