Karlsruhe Combined Solution
The Karlsruhe combined solution comprises two sub-projects which involve the new light railway tunnel (construction commenced 2010) and a road tunnel (construction commences 2016). The objective of constructing the light railway tunnel is to increase the capacity of the Karlsruhe public transport network. Furthermore, from an urban planning perspective, the area around the market place is to be remodelled into a proper pedestrian zone for a length of over 1 km. Schüßler-Plan has been commissioned to provide project management services and overall construction management. The particular challenge of this project is that all of the construction work is carried out solely within the central inner city area of Karlsruhe. This means that the Schüßler-Plan team faces complex assignments in connection with the technically demanding challenges posed by the special civil and tunnel engineering construction work in relation to the firm's project and construction management services.
