Dr. J. Grob & Partner AG

What Dr. J. Grob & Partner AG does

Dr. J. Grob & Partner AG is a privately held Swiss structural and civil engineering consultancy (Aktiengesellschaft) founded in 1994 in Winterthur, operating across three regional offices in Winterthur (headquarters), Frauenfeld (Thurgau), and St. Gallen. The firm delivers end-to-end engineering services across six core disciplines: structural engineering for buildings (Hochbau), bridge and infrastructure engineering (Infrastrukturbau), timber construction (Holzbau), special foundation engineering (Spezialtiefbau), earthquake and structural dynamics (Erdbeben / Bauwerksdynamik), and expert assessments / appraisals (Expertisen / Gutachten). Its work spans new construction, building preservation, structural rehabilitation, and seismic strengthening, with a project portfolio that includes flagship Swiss infrastructure such as the Europabrücke rehabilitation, the Andreasturm high-rise at Zürich Oerlikon, and the Kornhaus Swissmill silo upgrade in Zürich.

The firm's primary digital methodology is BIM2Field, which enables direct execution from Building Information Models on the construction site without traditional formwork and reinforcement drawings, applied in projects such as the Rohrbrücke Zulaufkanal Wülflingen and Gerichtsplatzareal Uster. The firm is ISO 9001 certified since 1997 (Bureau Veritas) and holds memberships in SIA, suisse.ing, SGEB, and SIA Feb GPO. Revenue is generated through project-based professional services contracts — direct mandates from private developers, public tenders from cantonal and federal agencies (notably ASTRA and Tiefbauämter), and partnerships with architectural firms serving as referral channels. The firm employs ~36 professionals, including ETH/TU/FH-qualified structural engineers, and operates under a management team led by Oliver Gasser (CEO) and Dr. Max Schläfli (Chairman/Deputy CEO), following a 2014 succession from founder Dr. Josef Grob in which BHAteam (Frauenfeld) joined as partner office and co-shareholder.
