en.Wedoany.com Reported - The restoration project of the Fourvière Notre-Dame tower in Lyon, France, employs the M368 multi-directional scaffolding system, carried out by the engineering team in two consecutive phases, with two towers restored each time. Each tower is equipped with a dedicated scaffolding system integrated with a construction elevator for material transport and high-altitude work.
The main challenge of the project lies in the architectural structure of the Fourvière towers: the octagonal geometry, numerous decorative elements, limited access, wind loads, simultaneous multi-trade operations, and the constant presence of visitors. These factors necessitated the development of a fully customized solution. To address these constraints, the team selected the M368 multi-directional scaffolding system, equipped with proximity cantilever frames to closely conform to the tower's shape. At the high spire, a specially designed 17-meter self-supporting and self-stabilizing structure was implemented to minimize anchoring to the historic monument and preserve its integrity. The installation also includes 23 working levels per tower, an additional 8 levels at the spire, as well as signage and protective devices to ensure visitor safety during construction.
Although the M368 system is a proven solution, its adaptation to the Fourvière towers required specialized design studies and calculation documentation to ensure structural stability throughout the construction phase. The significance of this operation lies in adapting an industrial solution to a complex heritage building while meeting safety and architectural preservation requirements. Safety is indeed a key aspect of this operation. Construction is carried out in a fully enclosed area to maintain permanent separation from the public, while logistics operations are scheduled during the earliest hours of the day to minimize impact on visitor flow at the site.
The assembly of each tower takes over a month, reflecting the technical expertise required for construction at one of Lyon's most iconic monuments. In total, the project will utilize two construction elevators, four scaffolding structures each nearly 50 meters high, and a structure reaching up to 67 meters.
