STEINMANN Ingenieure und Planer AG

What STEINMANN Ingenieure und Planer AG does

STEINMANN Ingenieure und Planer AG is a Swiss engineering and planning consultancy headquartered in Brugg (relocating to Baden in 2026), operating as part of the broader Steinmann Group under owner David Steinmann. Founded in 1937, the firm delivers surveying, civil and structural engineering, spatial planning, environmental, and infrastructure services to municipal, cantonal, and private-sector clients across Canton Aargau, with four offices in Baden, Brugg, Aarau, and Muri and a headcount of approximately 25 employees.

The company holds official Nachführungsgeometer (cadastral surveyor) mandates granted by the Canton of Aargau, providing it with state-sanctioned authority to maintain official land registry data. Its service portfolio spans official and engineering surveying, road and utility infrastructure design, building and structural engineering, environmental consulting, and 3D spatial planning. The firm has implemented ISO 9001 quality management (2025) and is operationalizing BIM (Building Information Modeling) methods, including a pilot for the Brunegg cantonal road renewal, signaling a shift from 2D drafting toward digital, model-based delivery. An in-house apprenticeship program has produced top-ranked graduates in cantonal examinations, supporting a steady talent pipeline.

Commercially, STEINMANN operates a project-based professional services model, billing against hourly rates, lump-sum project fees, and public-procurement contracts. Revenue is generated from a diversified base of cantonal and municipal public-sector clients (Gemeinden and Kanton Aargau) plus named industrial accounts such as ABB, Holcim, and HIAG. In January 2026 the firm integrated Plüss Bauingenieure GmbH, extending its structural-engineering capacity in the Lenzburg area and strengthening its offering for infrastructure and building clients within the canton.
