History The company was founded by Alexandre Giros and Louis Loucheur as Société Générale d’Entreprises S.A. (SGE) in 1899. SGE was owned by Compagnie générale d'électricité (CGE), now Alcatel, from 1966 until 1981, when Saint-Gobain acquired a majority stake. Companies acquired by SGE include Sogea (a civil engineering firm founded in 1878), bought in 1986, Campenon Bernard (a civil engineering and development firm founded in 1920), bought in 1988, and Norwest Holst (a British civil engineering firm founded in 1969 by the merger of Holst & Co, established in 1918, and Norwest Construction, established in 1923), bought in 1991. In 1988, SGE was acquired by Compagnie générale des eaux, now Vivendi. In 2000, the company changed its name to Vinci. In 2001, Vinci acquired Groupe GTM, which was a combination of Dumez, founded in 1880, and GTM, founded in 1891. In 2002, the UK business Norwest Holst was renamed Vinci plc. The company went on to acquire Autoroutes du Sud de la France (the Southern Freeways Company) in 2006, and Bachy-Soletanche, the world's second-largest geotechnical specialist contractor (after Bauer) in February 2007.
