In January 2018, PORR Bau GmbH . Department Railway Construction in cooperation with other PORR departments started construction works on the construction lot U2-18 Site in Vienna. The contract covers the construction site clearance for the future launch shaft for the tunnelling works, sewer construction work, as well as the collector structure in a more than 15m deep excavation pit in the middle of Matzleinsdorfer Platz.

By 2030, over two million people will live and work in Vienna. That is why the Wiener Linien is expanding its network. Following the extension of the U1 to the south, the U2/U5 interchange forms an important gap closure in the inner-city subway network. The expansion stage which is now being launched includes the extension of the U2 to Matzleinsdorfer Platz and the construction of the U5 to Frankh-platz/Altes AKH. It will require an investment volume of approx. EUR 950 million.

PORR Bau GmbH . Department Railway Conctruction proved itself with its engineering expertise in the realization of complex infrastructure structures and close working relationship with the customer. The implementation of the lot will be carried out in cooperation with the Specialist Civil Engineering Department (bored piles and drilled concrete substructures) and the Vienna Civil Engineering branch (asphalt works).

The challenges of the construction project: the inner-city location, the extensive transport measures and the realization of the main construction work as an island construction site at one of the main traffic junctions in the southern part of Vienna.

Since 2010, the Railway Department has been able to successfully implement 100 contracts for the Wiener Linien. In addition to flagship projects such as U1 South, this includes preliminary measures for the new U2/U5, such as the foundation investigations in the areas of Matzleinsdorfer Platz and Reinprechtsdorfer Straße, as well as the construction work for the Info Center U2/U5.
