## History

It was founded in 1862 by Carl Heinrich Gruner in Basel with a focus on water supply. He specialized in setting up gas stations and urban water utilities. The era of hydraulic engineering was started by Henry Eduard Gruner under the name of "Ingenieurbüro Dr. Gruner" in 1898. The next 40 years, the company was almost exclusively involved in the field of hydraulic engineering, hydropower plants and high dams worldwide. In the 1930s, his son, Edward Gruner drafted the idea of the Gotthard Base Tunnel, which he published in 1947 in his essay titled "Journey through the Gotthard Base Tunnel." George Gruner, the grandson of the founder, joined the office in 1938. This marked the onset of civil engineering activities in construction works. In 1942 was the foundation of Ingenieurbüro Dr. HE Gruner + Sohn (Engineering Office). In 1948, the company was renamed to Gebrüder Gruner, following the death of their father, Henry. This was followed by civil engineering work. In 1950, transportation planning was included as a new business area. In 1970, the company was restructured into a corporation (Gruner AG). In 1974 was the establishment of the subsidiary, Gruneko AG, which focused on energy economics and covered the areas of facilities engineering and energy installations.
In 1979, Böhringer AG became part of the Gruner Group in the business areas of local and regional civil engineering, utilities and waste management. 1980 witnessed the establishment of the Environmental Division. The companies, Tausky Leu Müller, Heinzelmann AG and Uli Lippuner AG became members of the Gruner Group between 1985 and 1990. In 1992, the subsidiary, Lüem AG was founded. In 1993, Gruner + Partner GmbH was founded in Leipzig. In the year 2000 was the establishment of the General Planning and Safety Divisions. The subsidiary, Tausky Leu Mueller, Bauingenieure AG was renamed to Gruner AG Ingenieure und Planer (Consulting Engineers) in 2001. Frey Strub AG became a subsidiary of Heinzelmann AG in 2001. Heinzelmann AG was renamed to Gruner Ingenieure AG in 2005. Likewise, in 2005, Berchtold + Eicher Bauingenieure AG became a member of the Gruner Group. Roschi + Partner AG, operating in facilities engineering and energy consultancy, was integrated into the Gruner Group in 2006. The companies of the Wepf Group were merged with Gruner + Wepf Ingenieure AG, St. Gallen and Gruner + Wepf Ingenieure AG, Zurich in 2008. Similarly, Gruner GmbH was founded in Vienna to increase its presence in Austria. The engineering firm, H. Tanner became a subsidiary of Gruner AG Ingenieure AG in 2009. That same year, Gruner International Ltd. was established to enhance international business. Kiwi Systemingenieure und Berater AG became a member of the Gruner Group in 2011. With the founding of Gruner Peru S.A.C. in Lima, the Group gains its first foothold in Peru. In 2012 the Gruner Group celebrates 150 years in business. In 2013 Stucky SA is integrated into the Gruner Group. The two time-honoured companies have historical links: Alfred Stucky, who founded the engineering company bearing his name in 1926, worked at Gruner in Basel from 1917 to 1923, first as an assistant and later as head engineer and joint partner. In the same year Gruner establishes a company in Stuttgart for the provision of fire safety solutions: Gruner GmbH Stuttgart. In 2014 the member companies of the Gruner Group in locations all around the world all operate under the Gruner brand, since 2022 also Stucky SA.
