The SBB shopping mall is located on the surface easement covered by the 1987 agreement. Since its creation, the building has never been renovated and the technical installations are at the end of their useful life. This situation and Geneva Airport’s desire to build a multimodal hub requiring major construction work prompted SBB to initiate studies for the complete renovation of the shopping mall. Given the numerous interactions and interfaces involved, the renovation project is an integral part of the CAP2030 project led by Geneva Airport.
