What Leonhardt, Andrä und Partner does

Leonhardt, Andrä und Partner (LAP) is a privately held German structural engineering consultancy headquartered in Stuttgart, founded in 1939 by Dr.-Ing. Fritz Leonhardt. The firm operates as a VBI Aktiengesellschaft (AG) following its 2013 conversion from GmbH, with 233 employees drawn from 15 nationalities across 15 office locations — 10 in Germany (Stuttgart HQ plus Berlin, Dresden, Erfurt, Frankfurt am Main, Hamburg, Köln, Magdeburg, München, Nürnberg) and 5 international (Taipei, Zürich, Madrid, New York, Prague). LAP delivers integrated structural engineering services spanning the full project lifecycle: object planning, structural engineering design, BIM-based digital planning, site supervision and management, bridge inspection and rehabilitation planning, independent structural review by licensed checking engineers, and expert witness services. Its core technical differentiators include BIM methodology across all project phases and historical innovations such as the incremental launching method for bridge construction (1949), perfobond rails (1984), carbon fibre tendons (1997), and neo-pin bearings (1998).

The firm's project portfolio centers on bridges — cable-stayed bridges (Danjiang Bridge Taiwan, 920m/450m main span), composite and steel bridges (Rheinbrücke Leverkusen, Mainbrücke Marktbreit, Rudolf-Wissell-Brücke Berlin, Neckarbrücke Benningen), and pedestrian/cycle bridges (Stadtgrabenbrücke Lübeck, Varvsbron Helsingborg) — alongside public buildings in healthcare, education, and culture. LAP generates revenue through professional services on a project-based, quote-driven model with no public pricing disclosure, serving a customer base dominated by federal, state, and municipal government clients (Die Autobahn GmbH des Bundes, DEGES, Berlin Senate, Taiwan MOTC) and architectural partners (Zaha Hadid Architects, gmp Architekten). Its wholly-owned subsidiary LAP Prüf- und Sachverständigen GmbH (est. 2014) provides independent checking engineering and expert witness services, and it participates in Integrale Generalplaner AG in Zürich for integrated general planning. Recognition includes the Theodore Cooper Medal (2026, Chenab Bridge), IStructE Supreme Award (2018, Tamina Bridge), Eugene C. Figg Jr. Medal (2022, Varvsbron), and multiple national design awards, reinforcing its positioning in the premium tier of structural engineering consulting for safety-critical and architecturally ambitious infrastructure.
