Danube Flats

Vienna, Austria

Austria's Tallest Residential Tower:
A New Landmark in the Sky

In Vienna's Danube City district, the towering presence of Danube Flats, the tallest residential tower, has left an indelible mark on the city's landscape. Standing at a height of 180 meters with 48 stories and 600 apartments, this project is regarded as an exceptional achievement of engineering and architecture.

To realize a project of this magnitude, a reliable partner with expertise in various fields was required. The executing contractor, Granit Bau GmbH, has selected Doka as its executive partner for formwork solutions.

Improved work environment and faster construction progress with Doka complex solutions

To ensure a safe job site at a greater height, the Xclimb 60 Protection Screen was utilized. To make the construction process more independent and faster, the core walls of the building were constructed using the Xclimb 60 climbing formwork and the Framax Xlife framework formwork system, without first having the respective floor slab poured. Additionally the Doka Loading Platforms with load capacity of 5 tonns were used to optimize the logistic, the material transportation and storage on the floors.

"The first test for our new, rentable Doka Loading Platform has been passed! This was confirmed by the Danube Flats site team. A total of 6 platforms, distributed over several floors, are helping to optimize materials logistics. The fact that the loading platform is delivered to the job site ready for use and can be set down to the structure without any loss of time was particularly emphasized.“
