DYWIDAG Systems (DSI) is a global technology group in the construction and mining sectors. The DSI Holding GmbH is based in Munich.^[1]

History[]

DSI was founded in 1979 as a subsidiary of Dyckerhoff & Widmann AG for the worldwide marketing of licenses for DYWIDAG products and systems. The main focus of the business was on civil engineering, with the pre-stressing and geotechnical market segments. In 2000, DSI began to develop a second business area in the underground mining sector with the development, production and sale of products and systems for mining and tunneling. With the merger of Walter Bau AG and DYWIDAG into Walter Bau-AG combined with DYWIDAG in 2001, DSI was also taken over in the new group. DSI's German engineering business was managed centrally by DYWIDAG-Systems International GmbH with offices in Nauen, Langenfeld, Königsbrunn, Unterschleissheim and Munich. In 2002, DSI acquired Suspa Spannbeton and split the German business into SUSPA Spannbeton GmbH, which operated as SUSPA-DSI GmbH until 2009.^{[citation needed]}

In 2004 the company had a turnover of 300 million euros with 1100 employees. After the bankruptcy of Walter Bau, DYWIDAG-Systems International was taken over in 2005 by the financial investor Industri Kapital for 168 million euros, which in 2007 sold DSI to CVC Capital Partners for more than one billion euros. In 2006 the concentration on new business areas in the area of tunnel construction and concrete accessories began. In 2007, the DSI network comprised around 90 companies, holdings, licensees and agents. In 2009, due to the economic crisis, sales declined by 27 percent to 518 million euros. This was followed by mergers of the subsidiaries SUSPA-DSI and contec to DYWIDAG-Systems International GmbH, Germany and ALWAG Tunnelausbau Ges.m.b.H. to DYWIDAG-Systems International Ges.m.b.H., Austria. In 2010, DSI was taken over by BAML (Bank of America Merrill Lynch) and Barclays Capital and sold on 1 April 2011 to Triton Private Equity for more than 400 million euros.^{[citation needed]}

In 2010, the company employed a total of 2118 people who generated sales of 620 million euros, 45% of which related to engineering and 55% to underground construction. The business activities in the field of civil engineering and underground mining are focused on the regions EMEA, North America, South America and Asia-Pacific.^{[citation needed]}
