In 2001, a vehicle-free apron was developed for the new terminal building and apron at Dortmund Airport.
Aircraft at 13 parking positions are serviced through underfloor systems providing power, pre-conditioned air, potable water, blue water, and sewage—eliminating the need for conventional service vehicles. Roediger supplied the wet services plants and equipment for five service tunnels.
The accessible underground service tunnels are equipped with pop-up pits. Aircraft connections are made manually using dedicated hose-reel systems. The required media are supplied through pipe networks installed within the tunnels, running from the terminal basement to the apron.
