On 18 May, students from the University of Rostock had the opportunity to experience the very interesting construction technology of bridge transverse displacement by several meters on site as part of an excursion by the Chair of Concrete Construction to the construction site of the station bridge in Lübeck. The eastern part of the bridge is to be moved about 7 meters closer to the western part of the bridge using hydraulic presses. In addition to the bridge transverse shifting, we were able to visit the entire construction site and ask the people involved questions. This gave us a unique insight into the planning documents. The challenge of the technical execution was explained to us and the corresponding solution approach was presented. The day before the excursion, the planning team from Inros-Lackner SE and the construction company Becker GmbH & Co. KG gave us detailed insights into the planning and construction of the building in a two-hour project presentation.

An interesting bridge construction project has been realized in Lübeck in recent years. At 115 years old, the old station bridge no longer met today's requirements and had to be replaced by a new structure in a complex inner-city environment. The new station bridge has two separate superstructures, which were built using rolled concrete girders. Both superstructures rest on solid reinforced concrete substructures. The structure is founded on deep foundations using large bored piles and shallow foundations. The superstructures are monolithically connected to the substructures at the flat-founded abutment via a frame corner.

The entire project can be divided into several stages. The transverse shift in May of this year was just one of them, until traffic is expected to flow again from fall 2024.

A building is currently under construction in Rostock that represents a milestone for the inner-city development of the Hanseatic and university city of Rostock. The extension of the town hall building.

The construction project includes the construction of two new buildings. On the one hand, this includes the construction of a “double-gabled building” in which the registry office will also hold marriage ceremonies. The “double-gabled house” closes a structural gap that was created by the destruction of a historic double-gabled house from the 14th century during the Second World War. The building will also house a new town hall, offices and conference rooms. The building project also includes the construction of a new administration building with modern room structures, for which the German Sustainable Building Council (DNGB) is aiming for gold certification.

On June 20, around 20 students from the University of Rostock took part in an excursion to the construction site of the town hall extension. At the beginning, Stefan Bölkow (Head of the New Construction/Refurbishment Department at KOE) and Torsten Ruwoldt from the planning office MHB Rostock gave a detailed and very interesting presentation of the project. Points such as: Construction site logistics, building pit shoring, structural details, structural waterproofing, design aspects, building boundaries, building heights, space utilization concepts, etc. were clearly explained.

After the presentation of the project in a construction container, we went to the construction site, where archaeologists were uncovering medieval foundations and documenting their location. At another point on the construction site, the production of large bored piles for a tangential bored pile wall could be observed.

We look forward to the next visit to the construction site and the opportunity to experience the town hall extension at first hand and witness the growth of the two buildings.
