The Palais des Congrès is part of the CO’Met project, Orléans Métropole, developed in Orléans alongside two other buildings—the sports arena and the exhibition center—providing a unified site for large-scale events.
The architectural project, designed by architects Jacques Ferrier and Populous, was carried out by Bouygues Construction, a global leader in construction operating in 60 countries. The structural works for the Palais des Congrès were executed by Maeg Costruzioni Spa.
The work involved the executive design of the steel elevation structure and BIM coordination across all disciplines.
A phased construction calculation model was implemented to account for the structure’s stiffness evolution during the building process. Initial phases included the assembly of the primary steel structure and the installation of temporary props, which were removed after the installation of the roof tension rods. Following the completion of the steel assembly and removal of temporary supports, the concrete for the composite slabs was poured. After the concrete hardened, the façade elements were installed.
The beams were calculated as composite steel-concrete structures, considering shrinkage and creep effects.
Verifications were conducted in accordance with Eurocodes and French National Annexes.
The Revit model was also enhanced with parameters and construction phases to highlight structural hierarchies and temporary works needed for assembly.
