SMB-SIS Site Services


The Site Services group (SMB-SIS) provides the CERN community with an optimal level of service in the areas of

  • person mobility (shuttle busses, cars, bicycles),
  • housing (managing CERN’s hotels, CERN apartments, contacts with private local market),
  • cleaning (offices and other areas),
  • installation (removals, special car plates),
  • mail distribution (inbound and outbound for CERN, and internal to the Organization)
  • catering (restaurants, cafetaria's, vending machines)

Mobility: The group offers a range of mobility services on the CERN sites.  This includes optimization of the capacity of vehicles in the CERN car pools (short term and long term rentals), maintaining the contracts with different suppliers of vehicles, and anticipating changing needs of the user community and resource planning. The car pool ensures the management of the repairs and maintenance of the vehicles, and also manages CERN bicycles (purchases, rentals and repairs). The group operates a car and bicycle sharing system, and also ensures the smooth operation of the CERN shuttle bus services (fixed lines inside and outside CERN, and on demand services for example to transport visitors) as well as coordination of car and bus rentals. The group operates the CERN mobility centre.

Housing: The group operates the hotels on the CERN site and CERN apartments, manages the reservation of Foyer Schuman in Saint-Genis, and coordinates contacts with local housing options (private market and negotiated prices with surrounding hotels). It monitors capacity usage, and service quality, and adapts its capacity and service levels to the needs of the user community. It is also responsible for planning preventive maintenance to keep the assets in a good state, notably the CERN hotels.

Cleaning: The group is in charge of all regular and periodical cleaning interventions covering ~340’000 M2 floor space, and 22’000M2 of windows in ~600 buildings and halls (including offices, public areas, laboratories, halls, workshops, stores, service areas, controlled areas, etc.). This also includes animal interventions (ants, rats, mice, foxes..) and snow clearance in front of the buildings. The cleaning service is also in charge of the cleaning operations needed during technical stops ans long shutdowns.

Installation: Providing the community assistance in dealing with removals (coming to CERN and leaving CERN) and in obtaining vehicle licence plates for the authorized persons. It provides support and documentation for staff with diplomatic privileges. It also handles CERN’s official exhibitions in collaboration with other Departments.

Mail: This includes the collection and distribution of internal mail, the conditioning and franking of outgoing mail, and the reception and redistribution of incoming mail and small packages.

Catering: The current catering services include 3 restaurants (R1, R2 at Meyrin and R3 at Prevessin), 8 cafeterias (buildings n°6, 13 , 30, 40, 54 , 774, 864 and 865) and over a hundred of vending machines.
