Implenia is a Swiss construction and construction services company. Implenia, with its headquarters in Opfikon near Zurich, employs more than 8,000 people in Europe and posted revenue of CHF 3.8 billion in 2021.
History
Implenia was created out of a series of mergers between Swiss regional construction companies. In mid-1997 ''Preiswerk Holding AG'' merged with ''Schweizerische Strassenbau- und Tiefbau-Unternehmung AG (Stuag) / Stuag Holding AG'' and ''Schmalz AG Bauunternehmung / Schmalz Holding AG'' to form Batigroup Holding, which was domiciled in Basel. Batigroup’s core competencies centred on traditional construction activities, including road building, poured asphalt, civil works, tunnelling and building construction.
Zschokke Holding’s roots dated back to 1872 and the founding of ''Aktiengesellschaft Conrad Zschokke'' by Conrad Zschokke (1842–1918) in
Aarau. In addition to building construction, Zschokke focused on general planning, general contracting and property management.
Having acknowledged the complementary nature of their businesses, Zschokke and Batigroup began talks about a possible merger in summer 2005. Following these discussions, the intention to merge to form ''Implenia'' was announced publicly on 15 November 2005.
Finally, the shareholders of Zschokke and Batigroup approved the merger at simultaneous AGMs held on 2 March 2006.
