## History

Today's Heitkamp BauHolding GmbH has its origin in the civil engineering company E. Heitkamp, which was founded in Herne-Wanne in 1892 by Engelbert Scharpwinkel. It originally had four employees. The company was originally known as E. Heitkamp. Towards the end of the 19th century, the company built canals and roads for the farmers in the neighbourhood.

### 1902

Heinrich Heitkamp, the son of E. Scharpwinkel, assumed the management of the still young construction company and expanded its field of activity by entering the mining business which was the characteristic industry in the Ruhr area at the time. In addition, he entered into other ventures. In the following decades, its construction activities were expanded beyond the limits of Herne and its original sectors to include civil engineering, railroad, and infrastructure projects, as well as mining services. At that time, the projects included, for example, the new construction of the Herne railway station, the construction of the Chemische Werke Hüls in Marl, earthwork, canal and regulation work for the Emschergenossenschaft and the Lippeverband, the beginning of motorway constructions. In addition, they worked in shafting-sinking activities for regional coal mines, such as the Shamrock Mine, Unser Fritz Mine and others.

### 1946 to 1963

In 1946, the E. Heitkamp Tiefbaugeschäft in Wanne-Eickel was renamed to Bauunternehmung E. Heitkamp GmbH. His sons Heinrich and Robert became shareholders along with their father, Heinrich Heitkamp, Sr. Following the removal of war debris from their building, the field of activity was expanded to include other areas. Buildings for government agencies and the Deutsche Bundesbahn were constructed and in the early fifties, the company started providing special mining services with underground track constructions.
In 1957, Heitkamp entered the power plant construction sector by executing a contract for the Westerholt power plant owned by Hibernia AG. For the first time, refuse dumps were used for the construction of dams and roads. Heitkamp participated in the complete expansion of the Ruhr expressway from Essen via Bochum to Dortmund as well as in the new construction of the railway line between Gelsenkirchen and Haltern am See.
This was followed by a participation in the construction of the Henrichshütte 2 steel plant in Hattingen as well as the Brassert power plant in Marl and the Springorum power plant in Bochum. A patent was issued on 28 May 1958 for the track-tamping machine developed by Heitkamp for underground track construction. In 1960, Heitkamp entered the tunnel construction sector when the company built the Erbscheidt tunnel in the course of the Bigge dam construction. In addition, Heitkamp was awarded contracts for the construction of the Federal Ministry of Defence in Germany at the Hardthöhe in Bonn. At this time, Heitkamp employed about 4,000 people.

### 1964 to 1980

In 1964, Robert Heitkamp took over the sole management and expanded the family company in the next decades to become one of the largest construction companies in Germany. In the same year, Heitkamp built the first natural-draught cooling tower for the power plant in Ibbenbüren. This was followed by 53 cooling towers in Germany and another 38 cooling towers worldwide, including countries in the African continent, Australia, Greece, the Netherlands, Spain, and the United States. In 1995, in the course of the largest individual contract in the history of the company, Heitkamp built two natural-draught cooling towers for the Lippendorf power plant, amongst others.

The civil engineering projects of were moved to make up the legally independent subsidiary Heitkamp Erd- und Straßenbau GmbH.

### 2000 until today

In 2001, the activities of former Railway Construction Division were transferred to the independent subsidiary Heitkamp Rail GmbH.
In this era, the company was involved in building the bridging structures (Bügelbauten) at the Berlin Hauptbahnhof; the construction of the transparent factory (Gläserne Manufaktur) of Volkswagen in Dresden and the Zollernhof in Berlin for the ZDF TV Studio; the construction of the National Bank building in Riga, Latvia; the construction of the double water-saving lock in Hohenwarte; the modernization of the former Mannesmann high-rise building in Düsseldorf; the construction and modernisation of the Marstallplatz Munich complex on Maximilianstraße; the construction of the new Cologne – Rhine/Main line of the Deutsche Bahn; and the construction of a university building, including a library, for Malmö University in Malmö, Sweden.
Due to a massive drop in orders in the mining sector and the increasing competition in the German construction industry, Heitkamp-Deilmann-Haniel GmbH decided at the end of 2005 to take drastic restructuring measures. In the course of these restructuring measures, the ATON GmbH acquired the parts of the domestic special mining and the international special mining division. ATON is today's Deilmann-Haniel International Mining and Tunnelling GmbH. Heijmans, a Dutch group of companies, acquired the Heitkamp Rail GmbH. In addition, the Turnkey Construction Office in Ratingen closed along with the offices in Düsseldorf, Dortmund, Hamburg, Munich and Stuttgart. Also, the civil engineering departments of the Bauunternehmung E. Heitkamp GmbH were combined to make up the independent subsidiary Heitkamp Ingenieur- und Kraftwerksbau GmbH.
In 2008, the Heitkamp-Deilmann-Haniel GmbH was renamed as Heitkamp BauHolding GmbH, which is its name today.
The Heitkamp BauHolding GmbH combines now the following four business areas: civil engineering and power plant construction under the Heitkamp Ingenieur- und Kraftwerksbau GmbH brand; infrastructure building under the Heitkamp Umwelttechnik GmbH, Heitkamp Erd- und Straßenbau GmbH brand; universal construction under the Domoplan GmbH, Heitkamp ProjektPartner GmbH brand; and special construction under the BuM Beton- und Monierbau GmbH, Bergsicherung Schneeberg GmbH, and Bergsicherung Ilfeld GmbH brands.
Currently, the largest project abroad involves the construction of the Olkiluoto nuclear power plant in Finland. They were involved under Heitkamp Erd- und Straßenbau GmbH brand in the construction of the Lake Phoenix in Dortmund-Hörde as well as the widening to 6-lanes and modernization of motorways, including the Autobahn 1, 2, 40 and 42 motorways deserves special mention. They were also involved in the redevelopment of the Kamener Kreuz
In February 2009, Jürgen R. Thumann, a great-grandson of the founder of the company, took over the majority of the shares in the Heitkamp Group. Since then, he has been the chairman of the board of directors. Heitkamp-Deilmann-Haniel GmbH changed its name to Heitkamp BauHolding.
In 2013, the company relocated to a new headquarters on the Pluto site in Herne. In 2014, the Heitkamp bridge and civil engineering company was founded.
