The Grande Halle Voyageurs in Bordeaux Saint-Jean, an imposing metal structure classified as a heritage site, has undergone an ambitious renovation, aimed at preserving its historic value while ensuring continuity of use.
Built in 1898, this 300 m structure is the largest railway glass roof in Europe and is central to the station’s operations, handling millions of passengers a year. Between 2012 and 2018, the consortium of setec tpi (lead contractor) and setec ferroviaire (co-contractor) coordinated and executed the works, which included restoring the framework, updating access and renovating the roof, while preserving the structure’s emblematic architectural features. In a particularly demanding technical context, the work teams had to deal with lead in the paintwork and asbestos in the window sealing. To avoid any risk of contamination, strict confinement was put in place, with totally enclosed work areas. The installation of scaffolding covering the entire hall meant that the work could be carried out without interrupting rail traffic, a major challenge in a station that is still in operation.
In addition to the need for structural reinforcement, replacing the existing ceiling and updating protection systems, the renovation works also focused on preserving the building’s aesthetic appeal and authenticity, to enhance the beauty of this landmark in Bordeaux.
