Building services engineering from one source: New visitor centre and expansion for Maestrani

The chocolate producer Maestrani based in eastern Switzerland is not only expanding its production facilities. A new visitor centre, the ‘Chocolarium’ with a café, shop, cinema, and event facilities catering for 100,000 visitors per year, is also being constructed at the Flawil site. The visitor centre is directly adjacent to the existing production building. Bouygues Energies & Services InTec is realising the sanitary facilities as well as the heating, cooling and ventilation installations.
