STUVA is an independent, private non-profit research institute founded in 1960. It deals with basic research and special projects mainly in the fields of urban transportation and underground construction e.g.:

special aspects of urban traffic (railway, mass transit, road and pedestrian traffic) in tunnels, on the surface and on elevated structures;

environmental protection against noise, vibration and exhaust fumes due to railway and road traffic;

tunnelling technology, especially: tunnel driving methods, tunnel structures and linings, waterproofing systems;

safety issues in tunnelling and tunnel operation, especially industrial safety, fire protection, operation conceptions;

underground services (micro-tunnelling) and utility tunnels.

Prof. Dr.-Ing. Alfred Haack


Executive board member


Born in 1940. The academic career comprises a civil engineering study at TU Hannover (1966) and a PhD in 1971 also in Hannover. From 1996 Haack is honorary professor in the field of Civil Engineering at the Technical University of Braunschweig, Germany, on the subject of structural protection.  He is since 1967 with STUVA; since 1973 director of STUVA-Department "Tunnel Construction"; since 1977 managing director of STUVA; and since 1995 executive board member of STUVA. He is since 1989 lecturer at the Technical University of Braunschweig (Germany); subject: "Protection of Underground Transport Facilities: materials, design and construction". He is also member of various DIN-Working Groups(standardisation); in some cases chairman.

Born in 1967. He works as a senior engineer for STUVA. After graduating as a civil engineer from University of Technology in Aachen, Germany, in 1993 he joined a German contractor, Philipp Holzmann AG, for two years as a design and development engineer for tunnels. From 1995 to 1998 he joined Herrenknecht AG, a well-known manufacturer for Tunnel Boring Machines, where he was in charge of applied geotechnics and various research programmes. Back with Ph. Holzmann, he was assistant tunnel manager, technical coordinator and claim manager at the Westerscheldetunnel project in The Netherlands from 1998 to 2001. In 1999 he got a PhD degree from the University of Wuppertal for his research on the adhesion of clayey soil in shield tunnelling. In 2001 he became area manager for the international tunneling activities of Ph. Holzmann. From 2002 to 2003 he was a senior project manager for Zerna, Koepper and Partner consultants engineers in Bochum, working on an engineering project for an extension of the Duesseldorf Metro. In 2003 he joined STUVA where he works an various research and consulting projects regarding tunnelling technology and tunnels safety.
