We are part of one of the most important strategic projects of the city of Brno – the construction of the multifunctional hall ARENA BRNO. The Building Structures Division prepared the design of reinforced concrete load-bearing structures, and provided the design of the pile foundation and securing of the construction pit, all at the stage of project documentation for the construction. The new multifunctional hall with a capacity of up to 13,300 spectators will provide Brno with state-of-the-art facilities for sports, cultural and congress events.
„We are pleased to be involved in a project of such fundamental importance for the city of Brno. Projects of this size are always a challenge not only professionally but also in terms of personnel, but our division is well prepared for both,“ says Ing. Vojtěch Petřík, Ph.D., Division Director of Obermeyer Helika. „The entire building is completely modelled in Revit software, which enables efficient collaboration between experts from different professions and minimises conflicts already at the design stage. We are currently preparing the production documentation of reinforced concrete monolithic structures for the contractor, HOCHTIEF CZ a. s., and at the same time performing author supervision within the building and construction profession,“ adds Ing. Petřík.
The multifunctional sports hall has an oval-shaped floor plan based on the shape of a hockey field. Its dimensions are approximately 150 x 108 metres. The entire building has two underground and six above-ground floors, reaching a height of 30 metres above the surrounding terrain. The roof of the hall is designed as a spatial steel prestressed strut structure measuring 137.5 x 95 metres. Its shape is based on the shape of the two halves of a spherical canopy and a cylinder. The entrance to the hall is designed from the west side of Bauer Street, it is formed by a ramp to the supply area and ramps to two floors of underground garages for 150 cars.
The hall is based on a 600 mm thick foundation slab, which is supported by drilled piles. Due to the complex geological conditions at the site and the foundation of the building below the groundwater level, the piles are also designed for tensile forces. The foundation slab and basement perimeter walls are designed as a watertight reinforced concrete structure, known as a white bathtub. The superstructure of the above-ground part is a precast reinforced concrete frame with monolithic communication cores. The grandstand is composed of precast inclined beams and bench elements made of lightweight concrete.
The construction schedule is very demanding: the construction of the first parts of the reinforced concrete foundation slab began in January 2024. The complete completion of the entire hall is planned for 2026.
