The multifunctional T-Mobile Arena comes to life with the contribution of our structural engineers

For the design consortium of Arch.Design and A PLUS architekti, our engineers prepared the detailed design documentation and provided author’s supervision. For the general contractor, HOCHTIEF CZ a.s., we delivered the fabrication documentation for the in-situ reinforced concrete structures.

The team was also responsible for the pile foundation design, retaining structures for the excavation pit, and the engineering preparation of the assembly area for one of the largest crawler cranes in Europe — the Liebherr LR 1750, with a lifting capacity of up to 750 tonnes.

Coordination of three structural offices On behalf of OBERMEYER HELIKA a.s., the project was led by experienced structural engineers Ing. Ctibor Havlík and Ing. Vojtěch Petřík, Ph.D.

“Given the involvement of three independent structural engineering offices — each responsible for different parts of the load-bearing system (cast-in-place concrete, precast concrete, and steel structures) — precise coordination was essential. In this case, coordination was carried out via the IFC format, as each office works in a different BIM platform. For interdisciplinary coordination within the building model, we used BIM Collaborate Pro, where the individual discipline models were uploaded progressively. When the 3D structural model is properly set up, it can also be efficiently used for numerical analysis. However, data exchange between the 3D modeling software and the structural analysis software requires thorough verification — it is not a fully automated process,” explains Vojtěch Petřík, Director of the Structural Engineering Division.

One arena, many challenges The multifunctional T‑Mobile Arena represents a technically demanding project that posed numerous challenges during both the design phase and construction.

The combination of precast elements, cast-in-place reinforced concrete structures, and a steel roof structure resulted in significant time savings. The use of 3D/BIM technology ensured efficient coordination of this complex building — not only during the design stage but also throughout construction.

T‑Mobile Arena / Brno, Czech Republic The multi-purpose arena will accommodate up to 13,300 spectators. Its roof is a spatial steel structure with tension ties, prestressed to enhance strength and overall stability. The roof dimensions are approximately 137.5 × 95 metres, and its geometry is derived from a combination of two half-domes and a cylindrical surface. The oval footprint of the arena, reflecting the traditional ice hockey rink layout, measures approximately 150 × 108 metres. The building comprises two underground levels and six above-ground storeys, with a total height of 30 metres above surrounding ground level. The entire structure was fully modeled in Autodesk Revit. Construction works commenced in 2024, with completion scheduled for autumn 2026.
