Infrastruktur und Umwelt


Three partners, who jointly own INFRASTRUKTUR & UMWELT, head the enterprise in person. You will meet these three partners not only during acquisition meetings. They will accompany a project throughout with their expert knowledge, experience and dedication. We are not out for quick returns but rather for solid concepts and sustainable solutions. Our goal is to establish long-term customer relations.
