U5 level under construction, September 2019

The Metro Station Red Town Hall is under construction subway station in Berlin district of Mitte . It is part of the extension of the U5 subway line from Alexanderplatz to the Brandenburg Gate , construction of which began in 2010 ( groundbreaking ) and which is due to open on December 4, 2020.

planning

Structure of the underground lines U3 / U10 and U5 at Alexanderplatz

The 120 meter long station is being built under Rathausstrasse directly in front of the Rotes Rathaus . The Berlin office CollignonArchitektur is responsible for the design of the station . The seven centrally arranged, 7 x 9 meter "mushroom head supports" on which the station ceiling rests are striking. Its shape is supposed to be reminiscent of the vaulted ceiling of the medieval Berlin town hall, which was in a similar location. The floor and walls of the station will be designed with black and white terrazzo . The gross floor area is 8000 m². The planning name was Berliner Rathaus underground station .

The station will have two levels: In the upper area, the U5 line will run on two four-meter-wide outer platforms , these are seven meters below the top of the street. A parking facility with four tracks is being built on the lower level, which can later be dismantled to two tracks with outer platforms (twelve meters deep) if the U3 or U10 to Potsdamer Platz should be realized.

Access structures with a distribution level below the road surface will be erected at both ends. One access will be on Spandauer Strasse north of Rathausstrasse in the west, and two more will be on Jüdenstrasse in the east. The side platforms are connected via the distribution levels, from here stairs and escalators lead to the surface. Furthermore, two elevators at the eastern end connect the platforms with the surface.

The existing U5 line currently ends in a four-track tunnel at Jüdenstrasse. This is currently used as a parking and sweeping system and must be converted in the course of the route extension. The Berlin City Hall station will be directly connected to this existing tunnel.

The station is built using a top-down construction . After the diaphragm walls , which are up to 32 meters deep , the HDI floor and the cover have been built, the new station will be built under their protection.

To the west of the station is the starting pit for the tunnel boring machine , in which, after the tunneling has been completed, a track change system and a defense chamber to protect the adjoining underpass of the Spree and Spree Canal will be created. All systems for operational equipment such as power supply, telecommunications systems and air conditioning are installed in the underground station building.

Completion and commissioning are planned for 2020 together with the route extension.

Until August 31, 2016, the station had the working title of the Berlin City Hall . Since September 1, 2016, the official and future station name is the Red City Hall .

construction

Archaeological excavations and uncovering of the old town hall, 2011
Parking facility on the U3 / U10 level, September 2019

In 2009, archaeological excavations began in the area of ​​the starting pit and the later station , which led to the Berlin sculpture find , among other things . At the same time, extensive line relocations were carried out in the later construction site area by the end of 2011.

The start of construction was delayed because archaeologists found unexpectedly well-preserved remains of the medieval Berlin city hall during excavations in front of the Rotes Rathaus . As a result, the station was rescheduled and an exit was relocated so that parts of these relics are now preserved and, if necessary , can be presented through an archaeological window . For technical and financial reasons, however, this window will remain closed for the opening so that the relics are not yet accessible and visible to the public.

While the adjoining tunnel has been in progress since spring 2012, construction work on the station began in early 2013.

62 million euros are estimated for the shell of the station.

With the start of work to close the gap on the U5 line in 2010, another transfer station was conceptually built with the Rotes Rathaus station. In the two-storey building, the  U3 / U10 line is on the lower level. Since the U3 or U10 is not expected to be implemented anytime soon, this level will initially be used as a four-track storage facility for trains on the U5. A possible conversion to a later train station with side platforms will be considered structurally.

The topping-out ceremony was celebrated on September 7, 2016, and around 3,000 interested people took the opportunity to tour the construction site on this day. The shell construction was completed in January 2017, after which the interior work began. By April 2019, the tracks had been laid on both station levels as well as in the adjacent track change facility and in the renovated existing tunnel to the Alexanderplatz underground station.

Connection

The underground station is to be served by the U5 line; there will be transfer options to BVG bus routes .
