Architectural and open space design of the U5 stop Stephansplatz (BIM project) Text automatically translated in your browsing language Automatically translated

With the U5, the HOCHBAHN is planning a new subway line that runs as a traffic artery across the city. The new line of the future U5 starts in the Bramfeld district, runs east of the Alster via the city centre and then west of the Alster via the UKE to the arenas in the Bahrenfeld district. In the section U5 East (Bramfeld - City Nord) a total of four new stops are planned over a distance of around 5.8 kilometres. The section of the U5 Mitte connects to the City Nord stop and leads via the city centre to the arenas. A total of 18 stops are planned on a route of approx. 19.1 kilometres in length with stand pre-planning. The stop Stephansplatz is located in the center of the city of Hamburg and in the middle section of the line U5. The new U5 stop structure will be located southeast of Dammtor station in an urban/landscape planning and monumental context in the area of Dag-Hammarskjöld-Platz, the Planten un Blomen park and the Dammtordamm road and will be oriented in a north-south direction. Among other things, it opens up the area around Dammtor station. In addition to the transition to the subway line U1, Dammtor station can be reached by S-Bahn, regional and long-distance transport connections via exit systems on the surface. At the time of this announcement, there are two different variants with regard to the specific spatial design of the new stop in the room. Essentially, the variants differ in terms of the structural scope and the estimated construction costs. A final decision on which variant will ultimately be implemented and thus also represent the mandate of the intended competition procedure is expected in early 2025 and will be communicated to the selected planning teams as part of the dispatch of the tender documents. The subject of the present competition procedure is the planning of the entire spatial expansion for the planned underground station Stephansplatz on the basis of the preliminary design as well as the free space planning design for the surrounding / adjacent outdoor facilities. The planning of the spatial expansion includes the design of the public areas of the platform level, the counter hall levels, as well as the staircases and lifts with all connecting paths to the exit systems. If necessary, the preservation of the original building by Karl Schneider from the 1920s must also be taken into account, an important example of New Building in Hamburg. It is currently being agreed whether further adjacent road spaces should be included in the planning. When processing the task, certain predetermined framework conditions must be observed. This includes, for example, the automated operation of the U5 with platform screen doors at the platforms. The promoter and the Free and Hanseatic City of Hamburg expect a solution that combines a high degree of safety, user-friendliness and comfort and a high design quality with high economic efficiency and the responsible handling of financial resources offered by public construction projects. In cooperation with Hadi Teherani Architects, Hamburg, and in close cooperation with the Free and Hanseatic City of Hamburg, HOCHBAHN has developed basic design and construction principles for the spatial expansions of all stations of the U5 and summarized them in a two-part design manual. These principles form the design framework for the new U5 stops and are to be translated into concrete designs by the planners. They offer planners appropriate freedom and scope for their own design ideas and interpretations. The design manual for the new U5 stops only partially covers the special requirements to be taken into account for the new Stephansplatz stop. Nevertheless, the planning teams can orient themselves on the proposals of the design manual and check to what extent certain proposals can be integrated into the concepts depending on the design.
