Revolution in bridge construction: New Bockfließer Brücke near Vienna opened!

Revolution in bridge construction: New Bockfließer Brücke near Vienna opened!

In the past few months, a lot has moved when expanding the north railway from Vienna Süßenbrunn to the Czech state border. A particularly remarkable project is the renewal of the Bockfließer Brücke (L13) in Deutsch-Wagram, which was officially released for traffic in winter 2025. The use of the flexible fabricate system Doka Unikit by Swietelsky AG, which turned out to be a real all -rounder among the formwork systems, was particularly exciting. The work took place during ongoing rail operations, which was a special challenge, after all, the tracks had to be continuously driven while working on the bridge.

The comprehensive construction measures needed a construction time of 11 months. The main work included the demolition of the inventory construction and the construction of two opponents and three bridge pillars with the innovative frame formwork Framax XLife. These pillars are impressive 13.48 m long and 100 cm thick, while the maximum height of the formwork is up to 8.70 m. The bridge itself has a length of 83 m and a width of 15 m, the strength of the construction varies between 1.25 m and 1.75 m. Particular attention was paid to compliance with the light space profile in order not to endanger the operation on the tracks.

innovative technologies in bridge construction

The application of the DOKA Unikit system stands out due to its flexibility and adaptability, as well as numerous projects all over Europe. The latest developments include the Jaruga and Aftetal Bridge and the A16 in Rotterdam, in which Doka successfully implemented its innovative formwork technology. The DOKA competence center in Amstetten, Austria, plays a key role here and offers highly qualified engineers who develop tailor-made solutions for complex bridge projects. The use of standardized rental parts not only makes the systems efficient, but also more sustainable, since they are reusable, which also comes into play in the Bockfließer bridge.

Another innovative element was the auxiliary pillar from the old stock of the bridge, which was reused. This shows how important sustainable approaches are in construction. Time -critical work on the center pillar was efficiently prepared by digital pre -assembly. A total of 22 driving mixers and 3 concrete pumps were used in the concrete of the structure, which processed an incredible 1,278 m³ of concrete in just 10.5 hours - this corresponds to an average of 120 m³ per hour. The excavation formwork was cut out by a hydraulic lowering system, which not only increased efficiency, but also increased safety during the construction phase.

The role of engineers

bridge construction engineers are indispensable when it comes to improving the infrastructure. They contribute to creating stable and safe buildings and use special software for stability calculations. This expertise is constantly updated by seminars and further training, as the VDI Wissensforum offers. These events offer engineers, project managers and other experts the opportunity to find out about the latest developments in bridge construction and to deepen their knowledge.

The most modern methods and technical possibilities are essential in order not only to build new bridges, but also to modernize or repair existing buildings efficiently. This also makes it clear in Vienna that bridge construction is far more than just connecting two bank - it is about security, sustainability and the challenge of finding innovative solutions for complex projects.

For all actors working in the industry, bridge construction remains an exciting field full of challenges and opportunities.
