Ed. Züblin AG operates as a major German construction company headquartered in Stuttgart, functioning as a key subsidiary within the STRABAG SE group. The company traces its origins to 1898, when Swiss engineer Eduard Züblin established a construction firm in Strasbourg. Following World War I, operations continued in Germany from 1919 onward, eventually consolidating under the Stuttgart-based entity.
The acquisition by STRABAG transformed Züblin's market position significantly. In 2005, STRABAG acquired a 53.6 percent stake in the company, which at that time employed over 7,000 people and generated approximately 1.5 billion euros in construction output. Today, STRABAG holds full ownership, and Züblin employs roughly 14,000 workers, establishing it as a leading force in German building and civil engineering.
Züblin's operational scope spans multiple construction disciplines, including turnkey construction, civil engineering, specialized foundation work, tunnel construction, building maintenance, and steel and timber construction. The company has delivered prominent infrastructure projects such as the Taunusturm and Central Business Tower in Frankfurt's banking district, and contributed to the European Central Bank building through shell construction work. Current undertakings include the controversial conversion of Stuttgart's main train station into an underground facility, requiring 25 individual excavation pits, and the North-South metro line in Amsterdam.
In February 2025, Züblin completed an extensive renovation of its Z2 headquarters building in Stuttgart, implementing energy efficiency measures and climate-friendly construction methods. The project houses nearly 450 employees and will receive platinum certification from the German Sustainable Building Council.
