In 1872, the public limited company Conrad Zschokke was founded, and in 1997 Batigroup Holding AG was formed. The merger of these two companies in 2006 led to the formation of Implenia. The company entered the Norwegian market in 2011 with the takeover of Betonmast Anlegg, followed by its entry into Austria in 2014 when it won the major Semmering Base Tunnel contract. In 2015, Implenia expanded its presence in German infrastructure construction with the acquisition of Bilfinger Construction.
A historic milestone was the opening of the Gotthard Base Tunnel project of the century in 2016, in which Implenia played a key role. The development of new markets continued in the same year with the "Grand Paris Express" project in France.In 2017 Implenia entered the German building construction market with the acquisition of Bilfinger Hochbau.
2020 saw a major event with the spin-off of parts of Implenia's development portfolio and the founding of Ina Invest. In 2023, Implenia extended its value chain into the real estate utilization phase for the first time with the acquisition of Wincasa.
