Project “Helix” nearing completion

The premium “Helix” project is intended to meet a new standard in Salzburg’s office and commercial real estate market. With a total floor area of around 18,500 m², it accommodates state-of-the-art, highly flexible spaces for offices and showrooms, as well as a hotel and gastronomy. The building stands out for its oval floor plan and complex construction. The top three storeys are supported as a ring structure by a circumferential steel truss construction. This alone weighs around 600 t and was structurally designed by IKK Group GmbH. The architecture was created by kadawittfeldarchitektur, while Herbrich Consult ZT GmbH was responsible for the building’s structural engineering. The approx. 6,200 m² unitised and stick curtain-wall façade was structurally designed by Thomas Lorenz on behalf of Metallica Stahl- und Fassadentechnik GmbH. “A particularly challenging aspect was the large number of different brackets, resulting from the composite steel–concrete construction, the diagonally continuous trusses, and the variable curvature of the façade in the floor plan,” says project engineer Krisztian Bodnar of Thomas Lorenz ZT GmbH. Overall completion and handover are planned for August 2024.
