This project includes extensive pipeline renovations in the entire Niederdorf/Oberdorf district, which are being performed by the water supplier, ewz and Energie360. In addition, the main alleys will be made accessible for people with disabilities and building connections will be renovated.

TBF is responsible as the representative for overall project management, general management, project planning management, interface coordination and technical support. Because of high pedestrian traffic and the tourist appeal, construction work is mainly carried out during the colder months.
