“VIENNA TWENTYTWO” – Facade Installation Well Underway

On the approximately 15,000 m² site, ARE Austrian Real Estate is developing two high-rise buildings and four residential buildings for housing, hotels, serviced apartments, as well as office and commercial spaces. In total, for Building Part 1, approximately 10,000 m² of facade area for Strabag, consisting of an element facade from the 2nd to 15th floor with suspended balconies, post-and-rail facades in the base and on the 16th to 17th floors, as well as 21,500 m² of external pilasters running along the entire height of the tower, are being structurally engineered. The standard elements have dimensions of W/H = 1,350/3,470 mm and a weight of approx. 600-700 kg. The facade elements are two-part and consist of the dense glazing elements and the balconies, which are screwed on from the outside, with attached pilasters. The major structural challenge was to transfer the loads of the balconies and pilasters through the glazing elements with their high glass content (glass content approx. 90% of the total height). For this purpose, high-quality solid aluminum blocks were thermally separated and installed in the area of the sheet metal cladding, into which all attachments are screwed with internal threads. In the corners, the additional requirement of an all-glass corner was also present. The overall completion of the facade is planned for August 2025, with Building Part 1 expected to be ready for occupancy in November 2025.
