PORR was heavily involved in rebuilding Austria after the Second World War – in difficult circumstances. One of the projects entrusted to the company at this time was the development of the Mariazeller Bundesstrasse road through Lower Austria. Prestigious buildings such as the Vienna State Opera also needed to be rebuilt. PORR was actively involved in steering Austria into a new and successful future. Constructed between 1953 and 1955, the Vienna Ringturm tower, which was a sensation at the time with its 21 floors, was Vienna’s second tallest building for some time.
PORR went on to prove itself as a bridge builder. At Bergisel near Innsbruck, it constructed a bridge at dizzying heights to carry the Brenner Autobahn. To this day, many of the key elements of this important north-south route are PORR structures. The 1960s saw the implementation of numerous large-scale general construction projects, including office buildings and business premises.
Work also began on a series of projects using the Danube as an energy source, in which PORR was to have significant involvement up until the mid-1990s. An impressive excavation technique was used for the first time during the construction of the Ybbs-Persenbeug power station. In order to waterproof the construction pit, weeks were spent driving planks into the river bed before the actual work began.
