Topping-out ceremony at DC2 in Vienna-Donaustadt
18. June 2025
Together with S+B Gruppe AG, PORR Group, and Commerz Real AG, the topping-out ceremony was celebrated for the approximately 180-meter-high mixed-use tower—an architectural highlight right next to the Danube.
Europe’s largest photovoltaic façade on a high-rise building is being constructed here – with 3,300 PV elements covering over 10,000 m².
DELTA Consulting is supporting this flagship project as a partner of Commerz Real from Germany – with extended monitoring and investor consulting provided by our team led by Marc Guido Höhne.
We congratulate everyone involved on this milestone and look forward to its completion in 2026!
