Implenia is a Swiss real estate and construction services company with activities in development and civil engineering in Switzerland and Germany.

[9][11] Due to the largely complementary business areas, Zschokke and Batigroup began talks about a possible merger in summer 2005.

[15] On 27 October 2020, Implenia announced an accelerated restructuring starting in 2021, marking a break with the construction group's years-long push for internationalization, which it declared over.

[16] Its stock market value halved over the past two years, largely due to previous project acquisitions and purchases (such as in Sweden between 2015 and 2017).

The company withdrew from unprofitable business areas in some markets (Sweden, Norway and Romania) and has since focused largely on Switzerland and Germany.

[10] In the rest of Europe, the focus is largely on tunnel construction, as in Austria, France, Sweden, Norway and Italy.

[16][18] In May 2021, Implenia completed the acquisition of BAM Swiss AG, a healthcare construction services provider in Switzerland headquartered in Basel.

[19] With this acquisition, Implenia took over BAM Swiss AG's current projects such as the planning and realization of the Aarau Cantonal Hospital, the BSSE in Basel – a modern laboratory and research building for biosystems science and engineering – as well as the Felix Platter Hospital project in Basel and an ETH student residence in Zurich.

[3] Implenia's business areas are divided into four divisions: Real Estate, Buildings, Civil Engineering and Specialties.
