Engineering Office GRASSL

What Engineering Office GRASSL does

Engineering Office GRASSL (Ingenieurbüro GRASSL GmbH) is a family-owned German civil engineering consultancy founded in 1950, headquartered at its Munich regional office (Machtlfinger Str. 5-7, 81379 München) and operating six additional offices in Hamburg, Berlin, Greifswald, Magdeburg, Düsseldorf, and Stuttgart. The firm specializes in the design, checking, supervision, and maintenance of civil engineering structures — principally bridges (highway, motorway, valley, pedestrian), tunnels (road, rail, waterway), flood protection measures, and special structures — and delivers services across all HOAI (Honorarordnung für Architekten und Ingenieure) service phases from preliminary requirements determination through construction supervision and long-term maintenance. With approximately 270 employees and an average tenure of 10 years, GRASSL serves public-sector clients exclusively, including federal agencies (DEGES, Die Autobahn GmbH des Bundes), state construction authorities (Landesbetrieb Straßenbau NRW, Autobahndirektion Nordbayern), and municipal governments across Germany.

GRASSL's service portfolio is organized around four core offerings — Design, Checking, Supervision, and Maintenance — supported by three digital methodology service lines: Building Information Modeling (BIM), Structural Health Monitoring (SHM), and a broader Digital Methods capability. The firm is described as a pioneer of BIG BIM applications in German infrastructure and conducts Structural Health Monitoring of approximately 300 bridges, tunnels, hydraulic structures, buildings, and special structures annually, providing data for damage analysis, remaining service-life determination, and preventive maintenance planning. Checking work is led by specialized structural, welding, and fire safety design checking engineers, with feedback loops between design, assembly, and testing informing a continuous improvement cycle. The firm runs an in-house podcast ('Baustelle Bauwesen'), maintains a multi-channel social presence, and sponsors the Hans Grassl Award (13th edition in 2025) for Master's students in steel bridge engineering at TU Braunschweig.

GRASSL operates a direct enterprise field-sales motion, engaging government clients through competitive bidding and direct commission for individual infrastructure projects across Germany; there is no international footprint, no indirect channels, and no product distribution. Revenue is generated exclusively through professional-services fees structured under the HOAI framework on a project-dependent basis, with no publicly disclosed pricing or revenue figures. The company is wholly owned and controlled by the Grassl family (Martin Grassl and Dr. Hans Grassl identified as key figures), with no external investment, public shareholders, or subsidiaries disclosed in the source data.
