The story

The company was established in Vienna in 1869 and was first listed on the Vienna Stock Exchange on 8 April of that year. In the late 19th century, it participated in the construction of numerous prominent buildings along the Vienna Ring Road, including the Haus der Industrie, and built exhibition pavilions and hotels for the 1873 World Exposition in Vienna.

In 1927, the two parent companies merged to form Allgemeine Baugesellschaft – A. Porr Aktiengesellschaft. During the interwar period, the company undertook major infrastructure projects, including the construction of the Grossglockner High Alpine Road. After World War II, PORR became increasingly involved in large national projects and in the development of office and commercial buildings, such as the Ringturm in Vienna.

In the 1970s, the company contributed to the development of the New Austrian Tunnelling Method, which had a significant impact on modern tunnelling techniques. From the late 20th century onward, PORR expanded beyond Austria into other European markets and the Middle East. In 2000, it became the majority owner of Teerag-Asdag, then one of Austria’s leading road construction companies.

Since September 2010, PORR has been led by CEO Karl-Heinz Strauss. Under his tenure, the group underwent restructuring and consolidation. In 2013, the company was renamed from Allgemeine Baugesellschaft – A. Porr AG to PORR AG. In 2014, its real-estate division was spun off, leaving PORR focused exclusively on construction. In 2017, the company acquired the Oevermann Group from Heijmans.

PORR was included in the Austrian Traded Index (ATX) in 2018.
