The business has its origins in two businesses:

  • Baumeister Lerchbaumer-Isola-KG[2] was founded by Anton Lerchbaumer (1879 - 1954) and his son-in-law, Franz Isola (1901 - 1968), in 1929. In 1954 Anton Lerchbaumer senior died. Franz Isola became the sole manager of the largest private building company in Austria. In 1968 Franz Isola, died and Anton Lerchbaumer junior (1913 - 1974) became manager of the company. The company became known as ILBAU AG in 1972.[3]
  • Strassenwalzenbetrieb was founded in 1895 and known as STRABAG from 1930.[4]

These two businesses came under the common ownership of BIBAG Bauindustrie Beteiligungs Aktiengesellschaft (subsequently renamed STRABAG SE) – a company listed on the Vienna Stock Exchange – in 1998.[4] In 1999, STRABAG acquired Strubag. In the same year, the company was delisted from the Vienna Stock exchange.[4]

In 2000, the holding company Bauholding STRABAG (or STRABAG SE since 2006) started a strong brand strategy throughout Europe, unifying all under the core brand "STRABAG". In Austria ILBAU and STUAG merged into the new STRABAG AG. The following year, the holding company became the major shareholder in German company STRABAG AG (based in Cologne).[4]

Subsequent acquisitions included Deutsche Asphalt Group in 2002, Walter Bau Group in 2005, a majority stake in Ed. Züblin in 2005, Adanti SpA, KIRCHNER Holding GmbH, F. Kirchhoff AG and Deutsche Telekom Immobilien und Service GmbH in 2008.[4]

In 2007, STRABAG SE launched its initial public offering on the Vienna Stock exchange.[4]

In December 2013 the Supreme Court of the Slovak Republic confirmed that one of the companies of the STRABAG Group participated in bid rigging cartel of construction companies (together with companies of Skanska group and Mota-Engil group) in 2004. Illegal conduct was associated with the tender for the execution of works for the construction of the D1 highway from Mengusovce to Jánovce in Eastern Slovakia.[5]


Current stakeholders are Russian oligarch Oleg Deripaska's Cyprus based Rasperia Trading, Hans Peter Haselsteiner's holding company, the Raiffeisen-Holding Niederösterreich-Wien group and Raiffeisen Group and UNIQA Group.[6]


The Chairman of the supervisory board is Alfred Gusenbauer. The business is managed by CEO Thomas Birtel.[7]


The company is organised into the following divisions: Building Construction & Civil Engineering, Transportation Infrastructure, Special Divisions & Concessions.[8]
