Abstract: |
The northernmost section 1 (StA 1) of the section of line being upgraded (ABS) and newly built (NBS) between Karlsruhe and Basel runs from Karlsruhe to Rastatt Süd. 16 km of new line is being built, which should be in operation in 2022. The core structure of StA 1 is the 4, 270 m long Rastatt Tunnel, the second largest engineered structure in the overall ABS/NBS Karlsruhe-Basel project after the Katzenberg Tunnel. The main contract for the construction of the tunnel was awarded in August 2014. The first preparatory construction measures on site started in summer 2013. Due to the prevailing conditions of topography and existing infrastructure and the continuously increasing requirements of approvals and codes, the construction of the Rastatt Tunnel poses great challenges for the engineers, which demand innovative solutions in design and construction as well as a collaborative approach from all those involved in the project. |
