New Danube Bridge in Linz

The HABAU GROUP connects. In Linz, our steel construction expert MCE is building the New Danube Bridge, an important piece of infrastructure for the city. Around 8,000 tonnes of steel are being used for the 400-metre-long, 31-metre-wide and 15-metre-high structure.

Havelland motorway (A10/A24)

With a volume of 1.4 billion euros, the expansion of the A10 and the general renovation of the A24 near Berlin is our largest civil engineering project to date. It includes expanding the motorway to six lanes, repairing large sections of road, demolishing and constructing bridges, nine interchanges, five parking and toilet facilities, noise barriers and much more.

Viertel Zwei

The visionary Viertel Zwei project surpasses conventional standards for modern living and working, combining them with moments of tranquillity thanks to its location next to Vienna’s Prater public park together with the site’s own expansive green spaces. It was the first project in Austria to be awarded the ÖGNI Platinum Certificate for its sustainable design. The total investment volume amounts to 750 million euros.

Post am Rochus

For us, sustainability is not just an empty promise. And buildings such as Post am Rochus, which encompasses an innovative ventilation and cooling system, bear testament to our promise to build for the future. The HABAU GROUP was awarded the DGNB Gold Certificate by the ÖGNI (Eng.: Austrian Society for Sustainable Real Estate) for this project.


ZEELINK refers to a 74.4km-long pipeline project. The high-pressure gas pipelines extend across long stretches of North Rhine-Westphalia and partly through the Rhine River, one of the busiest waterways in the world.

Diesterweggasse School

A future-fit building for education. The pupils at Diesterweggasse in Vienna-Penzing have benefited from a suitable location for their studies since 2018. BAUMGARTNER built the entire shell construction using solid cross-laminated timber elements.

Stuttgart 21

ÖSTU-STETTIN is building the Filder Tunnel and the Ober-Untertürkheim Tunnel, with a respective length of 9.5 and 6 kilometres, as part of the centennial ‘Stuttgart 21’ project. They are important feeders for the terminus station, which will be transformed into an underground through-station when fully operational. Tunnelling under the Nackar River is a particular challenge in this respect.
