Büchting + Streit

What Büchting + Streit does

Büchting + Streit AG is a Munich-based, owner-managed structural engineering firm founded in 1960, focused on bridge and tunnel design plus general civil/structural engineering. With offices in Munich, Nuremberg and Friedberg and 60+ employees, the firm has completed more than 1,000 bridge structures over six decades. Its technical core spans concrete and composite bridges, segmental construction, semi-integral bridge design and ultra-high-performance concrete (UHPC), demonstrated by first-of-kind projects such as the Dürnbach railway bridge (first UHPC railway bridge in Germany) and the Scherkondetal Bridge (first semi-integral railway bridge in Germany, 2012 German Bridge Construction Prize).

The firm operates two subsidiaries — B+S Prüfingenieure GbR (structural testing and inspection) and B+S International GmbH (international markets) — and maintains a long-running R&D partnership with Bauunternehmung Bögl dating to 1973, alongside academic integration with TU Munich through Prof. Oliver Fischer. Revenue is generated through professional engineering services billed under the German HOAI fee structure, primarily serving public-sector infrastructure clients including Deutsche Bahn, Autobahndirektion Südbayern, DEGES and DB Projekt Stuttgart-Ulm. Standards-setting participation in AHO, DIN and fib committees, plus approved Prüfingenieure status for rail and highway works, support its role in Germany's bridge engineering market.
