Caisse d’Epargne Lorraine Champagne-Ardenne wanted to design an amphitheatre in which to hold internal and external events. L’Amphi, the Caisse d’Epargne’s 8 450 sq. ft. amphitheatre, stands opposite the Metz train station, near Centre Pompidou and the future convention centre. It is divided into several spaces:
Nine months of work were needed to complete this project. It involved a project team composed of a dozen Korus Nord Est employees plus 20 regional companies, for a total of approximately 150 people working on site.
The Architecture Concept agency assisted Korus during the feasibility phase of this project. This venue boasts special acoustic treatments that are characteristic of this type of building: sound propagation and absorption on the walls, but also reduction of noise at the source (sound traps, oversizing of ventilation ducts and motors to limit the air velocity to 1 m/s, which is the audible limit for humans).
A primary structure composed of 25 tonnes of steel to support the false roof* was mounted on the amphitheatre’s ceiling. In total, 17 km of electrical cable, 420 litres of paint and 4 air handling units (AHU) with a total maximum air flow rate of 34,000 m3/h were needed to complete this major project.
