Bilfinger SE (previously named Bilfinger Berger AG) is a European company specialized in civil and industrial construction, engineering and services based in Mannheim, Germany.


Bilfinger dates back to 1880 when August Bernatz founded Bernatz Ingenieurwissenschaft as an engineering business: it became known, from 1886 as Bernatz & Grün and, from 1892, as Grün & Bilfinger when Paul Bilfinger replaced Bernat as partner. In 1970 Grün & Bilfinger acquired a majority stake in Julius Berger-Bauboag AG, itself a merger of two companies, Julius Berger Tiefbau AG and Berlinische Boden-Gesellschaft AG, both founded in 1890. The combined business, fully integrated in 1975, finally took the name Bilfinger & Berger Bauaktiengesellschaft. In 1994 the acquisition of Razel Company took place. In 2001 the business changed its name to Bilfinger Berger AG. In 2005, Bilfinger bought all shares of Babcock Borsig Service Group from Deutsche Beteiligungs AG. In 2008 the company sold Razel to group Fayat for 137 million euro. In October 2009 the company acquired directly MCE Beteiligungsverwaltungs GmbH itself, a business based in Linz focused on the design, construction and maintenance of facilities in the process industry and the energy sector. In June 2010, a prospectus was issued with the aim of listing Bilfinger Berger Australia on the Australian Securities Exchange via an initial public offering. In July 2010 the listing was abandoned with a trade sale to Lendlease agreed in December 2010. In 2010, services contributed to 80% of the company's total output volume of €8,123 million and EBIT for the services division amounted to €297 million. In November 2011, Bilfinger acquired 98 percent of shares in Neo Structo Construction Private Ltd., located in Surat, India, for a purchase price of €47 million. In 2010 Bilfinger became a Societas Europaea (SE). In December 2014 Bilfinger signed a deal to sell the construction division to Switzerland's Implenia AG. It had once been Germany's second largest builder. In June 2016 Bilfinger announced the sale of the facilities management and real estate business to Swedish financial investor EQT. In February 2018 the company announced that it would seek damages from the former directors of the company after alleged breaches in compliance and a series of acquisitions that failed to create shareholder value. After securing shareholder consent in June 2020, Bilfinger reached a settlement with the former Executive Board members. The settlement with a total volume of €18.2 million ends the assertion of claims of for damages by Bilfinger.

In March 2009, a building collapsed in Cologne due to the nearby construction site for the Cologne Stadtbahn Nord-Süd-Stadtbahn . The collapse is suspected to be caused by the construction works, and to several irregularities. In June 2020, Bilfinger reached an out-of-court agreement that settles all civil claims arising from the collapse of the city’s municipal archive building. Several other construction projects are suspected to have been conducted with irregularities: the Düsseldorf Stadtbahn Wehrhahn-Linie , the Nuremberg–Munich high-speed railway and the Bundesautobahn 1. In November 2018, Bilfinger was sued by Christopher Steele, who alleged that the company owed €150,000 for an investigation into Bilfinger's activities in Nigeria and Sakhalin.
