Porr

The Allgemeine österreichische Baugesellschaft was founded in 1869 in Vienna.[4] That same year took place the first listing on the Vienna stock exchange and the establishment of several Vienna Ring Road buildings of 19th century, such as the House of the Industry on Schwarzenbergplatz. In 1873 the company established erection of seven exhibition pavilions and numerous hotels for the World Exposition in Vienna.

Arthur Porr, a concrete construction pioneer, and O. Stern founded the A. Porr Betonbauunternehmung Gesellschaft mbH in 1908.

The merger of the two parent companies for Allgemeine Baugesellschaft - A. Porr Aktiengesellschaft was carried out in 1927. In 1930, the company pioneered with the construction of the world-famous Grossglockner High Alpine Road. In the interwar years Porr participated in construction of numerous power plants, roads, railways and industrial buildings. During the occupation after the 2nd World War the company belonged to Soviet-run USIA-Betrieben.

This was followed by the construction of prestigious office and commercial buildings such as the distinctive Ringturm in Vienna in 1960. Porr also acted increasingly as a general contractor for major national projects. In 1973 the construction of the Vienna International Center took place, the Vienna UNO City. In the 1980s, the group expanded its activities in Central and Eastern Europe. In 2000 Porr became the majority owner of the Teerag-Asdag AG, the most important road construction company in Austria.

In 2008 the company was already an international construction group with subsidiaries active in 16 European countries. The Turkish Renaissance Group got involved in 2009 with 10,22 percent of the Porr Group. Together, companies founded a 50:50 joint venture called Porr Construction Holding. In 2010 in the context of the BUWOG-Affair came investigations on Austrian Porr departments.[5][6] Despite the international activities at the time, 70% of the revenue came from construction projects in Austria, the remaining 30% from Germany, Switzerland and Eastern Europe.[4]

Since September 2010 Karl-Heinz Strauss[7] is the CEO of Porr.[8] By the time, the Porr Group has been extensively restructured. In 2011 Porr took over the Teerag-Asdag shares of Wiener Stadtwerke and thus becoming the only owner. The board of the company in December 2011 announced the decision of buying the Treves Lime, Dolomite and Cement Plant (TKDZ) in Wellen.[9] In 2012, the Bank Austria sold its 38% shares in the company to Karl-Heinz Strauss for around 80 million euros, so that Strauss with 44% of voting share became the largest single shareholder.[10] Moreover, the company Strauss & Partner, founded in 2008, which operated projects such as Euro Plaza in Wienerberg and Monte Laa, was brought in the group.[7][11][12] In 2013 the company name was changed from Allgemeine Baugesellschaft - A. Porr AG to PORR AG, with which the group appears internationally.

In July 2014, Porr increased its shares in UBM from 41,33% (until 1991 Union-Baumaterialen) back to a controlling stake.[13]
