Austria's Tallest Skyscraper: Innovative Construction of DC2 in Vienna

Vienna's New Tallest Skyscraper

• 🇦🇹 Vienna, a city known for its cultural landmarks, is set to gain a new tallest building, DC2, which is redefining skyscraper construction.
• 🏗️ While not as tall as its predecessor, the Millennium Tower, DC2 is notable for its innovative construction methods being used in a city not traditionally known for high-rise development.

Foundation and Core Construction

• 🚇 The project involved a massive excavation for five basement floors, requiring foundations over 22 meters deep, complicated by surrounding infrastructure like highways and a river bridge.
• ⚙️ A rail climbing system (RCS) from PERI was employed for the central core, acting as formwork for concrete and providing protection from the elements, allowing the core to be built 2.5 floors at a time.

Advanced Formwork and Reinforcement

• 🧱 PERI's Maximo and Quattro formwork systems were used for constructing columns and floor slabs, supported by reinforcement scaffolding.
• ⛓️ Steel reinforcement bars form a cage within the concrete, adding significant strength and rigidity to the structure.
• ⬆️ A specialized material hoist innovated by PERI efficiently moves people and materials, reducing reliance on tower cranes and speeding up construction.

Exterior Innovation and Redesign

• ☀️ The skyscraper's facade will be covered with photovoltaic elements to generate energy, a first for a European skyscraper.
• 📐 DC2 underwent a redesign, resulting in balconies and loggias surrounding the building and increasing its final height, though delaying its completion.

District Development and Conclusion

• 🏙️ DC2 is the final piece of the Donau City district, a major regeneration project on a former landfill site, transforming it into a modern urban center.
• ✅ Despite initial challenges with the foundations, the construction has proceeded smoothly, with the tower now nearing completion and set to offer residents stunning views of Vienna.
