This contract falls within the project for the electrification of the bus depot in Petite-Ile, currently used for the outdoor storage of approximately 80 buses. In order to accommodate electric buses, the site must be fully equipped with a new high and low voltage electrical infrastructure, as well as the necessary structures for the placement of future charging systems, adapted to fire prevention measures specific to electric-powered buses. The services include, in particular: 1. High voltage electrical substations and distribution • Construction of a new outdoor substation to replace the existing guard post (complete demolition of the building). This substation will house the HT cells, four dry transformers of 2,000 kVA, low voltage general panels, and auxiliaries. • Adaptation of the existing substation located in the main building, including the replacement of transformers and the addition of a specific distribution board for supplying the chargers. • Connection of equipment to the internal high voltage network of STIB (11 kV network). 2. Low voltage distribution and power supply of chargers • Supply and installation of cable trays, risers, power cables, and supporting structures for energy transport between the substations and future chargers. • Installation of low voltage distribution boards dedicated to supplying chargers and lighting. 3. Charging structures and metal fittings • Complete dismantling of existing canopies and their equipment. • Construction of new large-span metal canopies allowing for: o the attachment of charging hoods, o the passage of cable trays, o integration of lighting elements. These canopies are designed to cover the bus parking alignments and support the charging equipment. 4. Fire safety and compartmentalization • Construction of firewalls made of prefabricated concrete to compartmentalize the parking alignments and limit the spread of a fire. • Creation of fire corridors compliant with SIAMU requirements. • Installation of local and general emergency stops allowing the disconnection of power to the chargers. 5. Development of external surfaces • Demolition of existing islands and canopies and complete renovation of the concrete slabs necessary for bus traffic. • Reshaping of slopes, renewing rainwater drainage, and placing technical gutters. • Construction of localized slabs dedicated to the placement of chargers. 6. Lighting and low currents • Installation of a new outdoor lighting system that meets the EN 12464-2 standard, with several levels of intensity. • Relocating, re-commissioning, and rewiring low current equipment (cameras, operational phones, Wi-Fi), as well as implementing temporary cabling during the work. 7. Phasing and maintaining operations • The work will take place while maintaining activity, with a progressive phasing that allows the operational functionality of the depot to be preserved. • Coordination with the temporary parking at the neighboring site (“Leonidas”), used to relocate some of the buses during the work.
