A bubble wrapped station
The renovation of Chemnitz Main Station lies at the heart of a larger initiative to improve transport links across the region. Within the scope of this work is the incorporation of the tram network into the existing railway system, which will streamline the city’s transportation scheme and improve its efficiency.
It was this element of the project that proved most challenging to the BuroHappold Engineering team. As the station itself is a historic building with beautiful ironwork, our engineers had to find a way to adapt its solid, reinforced concrete structure into a more open plan design that would allow trams to pass through, without compromising the building’s strength or original features.
Our engineers developed a BIM model of the station that allowed us to assess a variety of structural solutions. We decided to strip the building back to its framework, and then incorporate this strong base within our new design. We upgraded the existing parts as required to retain the original features, and then connected them to additional steel components to create a strengthened super skeleton that was robust enough for the interior space to be opened up to accommodate the new tramlines.
To match the improved internal space, we worked alongside the architect to give the station facade a contemporary twist by cladding it with 100 innovative air cushions that are illuminated by low LED lights. These give the building a high design look, while also providing exceptional protection from heat transfer and resistance to fire.
As a result of our careful initial modelling and subsequent intelligent solutions, we were able to unify the old and the new within one harmonious design. Chemnitz Main Station is now a light, modern space that provides the people of Chemnitz with a cohesive multimodal transport hub.
