In the last few years, HOCHTIEF has systematically expanded its concessions business. The intensified focus on public-private partnership (PPP) projects reflects the company's strategy oriented to profitable growth. To increasingly focus on public-private partnership (PPP) projects is a logical step within the framework of the company's strategy oriented to profitable growth. With public coffers empty, many major projects can only be realized if private capital is invested.

World-wide, HOCHTIEF is currently involved in as much as 32 PPP projects with a total investment volume of more than EUR 13 billion.

HOCHTIEF has a leading role in the field of privately financed infrastructure both internationally and in Germany. Current PPP projects include 16 toll roads and 16 projects in public-sector building construction. This is supplemented by the six airport holdings of the HOCHTIEF Airport division .
