SETEC was formed in 1957 by Henri Grimond and Guy Saias, and is currently one of France's largest engineering firms, with over 2 100 employees. The entire capital of the Setec Group is owned by its directors and principal engineers. Therefore Setec is completely independent with respect to construction companies, banks and industrial companies.

SETEC carries out all work involved in the course of a project, from feasibility studies to commissioning. For large, complex projects, a multidisciplinary team is formed, combining the expertise of the SETEC group's best specialists in each field, directed by a project leader.
