Office history

Zivilingenieurbüro Sammer was founded as a two-man office in a two-room office in 1987. The aim was to create and offer our clients an efficient infrastructure with which to handle the growing tasks of traffic planning consultation. Meanwhile, the two-man office has evolved into a traffic planning office with eight employees, the number of clients increased significantly, and the office premises have been enlarged accordingly. The office operates in Austria and on an international level, focusing on traffic and environmental planning, consulting and research.
