Six-lane expansion and general renovation across 65 kilometres: the 1.4 billion-euro public-private partnership project is the largest contract so far in the company history of the HABAU GROUP and has now been successfully released for traffic.
After an almost five-year planning and construction phase for the six-lane A10 and the completely renovated A24 near Berlin in Germany, the way is now clear as of 11 November 2022. With a volume of 1.4 billion euros, the expansion, general renovation and operation and maintenance of the motorway sections for a total of 30 years is the HABAU GROUP’s biggest project to date. The contracting authority of the mega project is DEGES (Deutsche Einheit Fernstraßenplanungs- und -bau GmbH) on behalf of the Federal Republic of Germany and the central organisation Autobahn GmbH des Bundes. It is being implemented in a consortium consisting of HABAU PPP together with Invesis. The planning and construction works were carried out by a working group made up of HABAU Hoch- und Tiefbaugesellschaft m.b.H. and Wayss & Freytag Ingenieurbau AG. Now, aside from remaining work, the expansion and modernisation have been completed on schedule.
“As an internationally operating full-service provider with Upper Austrian roots, we feel proud and are particularly pleased to be able to implement this mega project in collaboration with excellent partners”, says HABAU GROUP CEO Hubert Wetschnig. “With the early completion of the construction phase of one of the busiest sections of the German capital region, we have achieved an important milestone. This has enabled us to successfully demonstrate our know-how even for projects of this dimension.”
Traffic revolutionised in one of Europe’s most important east-west links
The formerly four-lane A10 between the motorway junctions Havelland and Pankow (northern Berlin ring) has been expanded to six lanes over 30 kilometres. The four-lane, roughly 30-kilometre-long section of the A24 between the Neuruppin and Kremmen junction was thoroughly renewed, whereby the hard shoulders were widened so that, when necessary, they can be temporarily released for traffic over a stretch of 16 kilometres, depending on the volume of traffic.
As part of the works, numerous bridges had to be torn down and 39 bridges newly constructed. In addition, seven junctions, six parking and toilet facilities and around 20 kilometres of noise barriers were also built from scratch. Environmental protection and landscaping measures also represented significant partial services.
Following the opening to traffic, several remaining works are still to be completed, such as the dismantling of the provisional median crossings and the provisional emergency stop bays, the removal of the building site markings and the closing of the crash barriers in these areas. These works will be completed by the end of the year without interruptions to traffic.
Digital construction planning with BIM
All details that were necessary for the implementation of a construction section were digitally planned using Building Information Modelling (BIM) and will be further processed in the as-built model throughout the entire operation and maintenance phase. This considerably increased the efficiency, planning security and transparency.
“BIM and the topic of digitalisation in particular form the foundation for improved decision-making, accelerated processes and more innovation in the construction industry. This is also evident in the A10/A24 project”, explains Wetschnig in conclusion.
