Contract type: Turnkey Design and Build Basis
A span of 60 meters for the two main halls (banquet hall and conference hall for more than 1,100 guests) was the most spectacular task of the project. Heavy 4,75 meters high prefabricated concrete beams was the solution allowing us to start the suspended ceiling before the slab. These 1,200 tons beams were lifted by an hydraulic device.A cupola looking like the « Invalides » in Paris was built in GRC prefabricated panels and two large cupolas inspired from the « Opera » in Paris were built in metallic structure, covered by aged-copper sheets.
The façade was totally prefabricated with white architectural elements enabling us to complete the project in less than 18 months.
