Bouygues Energies & Services was tasked with the overhaul of the high- and low-voltage electrical installations. This involved equipping all 11 floors of the main building with electrical wiring, distribution systems, lighting systems, security systems, phone networks and data transfer networks. To account for the building remaining occupied, the work was carried out in three phases.
Also assigned to Bouygues Energies & Services was the control of all the systems, including managing the heating, air conditioning, lighting and openings for all of the workstations. During the tender process, the Security & Automation department adopted a bold approach by presenting an option that involved installing systems with a centralised control centre on each floor, rather than in each office. This innovative solution dramatically reduced the number of devices necessary for managing the systems.
