Marienhof Station, Second Core S-Bahn Route, Munich
The city of Munich is growing rapidly – and its S-Bahn railway network, originally designed for 250,000 passengers, is now bursting at the seams as it copes with around 850,000 passengers a day. The future Marienhof Station will be the central stop on the Second Core S-Bahn Route in Munich, which is being built to provide some much needed relief to the S-Bahn system. Commissioned by Deutsche Bahn, Implenia is taking the technical lead on the new station as part of a joint venture with Hochtief. The complex infrastructure construction project requires high-level skills in special foundations, tunnelling and concrete construction. It is being built right in the heart of Munich’s Old Town, directly behind the City Hall (Rathaus). The new station is located around 40 metres below the surface and is the deepest tertiary construction project in Munich’s history. Logistics are made very challenging by the tight confines and by the hustle and bustle of the city centre, with heavy pedestrian and cycle traffic as well as residential car traffic and deliveries. Owing to the sensitive built environment around the station, construction work has to proceed with great care, with extensive monitoring and various counter-measures required to avoid damaging or disturbing existing buildings.
