What BTG Buro fur Technische Geologie AG does

BTG Büro für Technische Geologie AG is a privately held Swiss engineering geology consulting firm headquartered in Sargans (Canton St. Gallen) with a branch office in Chur (Graubünden). Founded in 1944 and registered as an Aktiengesellschaft, the firm employs approximately 13-15 geologists, earth scientists, and geotechnical engineers. It delivers applied geology and geotechnical consulting across seven service areas: underground construction (tunnels, galleries, caverns), general geology and geotechnics, natural hazard assessment (landslides, rockfall), hydrogeology and energy, contaminated sites and environmental services, mineral resources, and 3D modeling.

The firm's technical practice is built on advanced geological modeling tools — Leapfrog for 3D geological models exported in IFC for BIM integration, RAMMS for rockfall simulation, SPRING for groundwater modeling, and XRF for in-situ contamination assessment — augmented by the Innosuisse-funded GEOL_BIM digital interface developed with the Swiss Geologists Association CHGEOL. Modeling services are delivered jointly with strategic partner Dr. von Moos AG, enabling combined 3D geological, geomechanical, groundwater, and BIM packages that neither firm offers independently.

BTG generates revenue through project-based professional services fees, with custom proposals quoted per engagement rather than published pricing. Its go-to-market is enterprise field sales — direct B2B consulting relationships with federal agencies, cantons, municipalities, Swiss railway operators (SBB, RhB), hydropower companies (Repower, Kraftwerke Linth-Limmern, Kraftwerke Sarganserland, Kraftwerke Hinterrhein), and private building owners, engineers, and architects. Several hydropower mandates have been continuously held since 1974 and 1982, evidencing deep institutional client retention. Marketing is conducted through professional reputation, project portfolio visibility, scientific publications in peer-reviewed journals, and association membership rather than digital channels.

Core offering

BTG Büro für Technische Geologie AG is an applied geology and geotechnical consulting firm providing specialized services in underground construction (tunnels, galleries, caverns), natural hazard assessment (landslides, rockfall), hydrogeology, contaminated site investigation, mineral resource consulting, and 3D geological/geomechanical modeling with BIM integration for public infrastructure clients in Alpine Switzerland.

Product overview

BTG Büro für Technische Geologie AG is a geological and geotechnical engineering consulting firm that provides specialized applied geology services, not a software product company. The company operates as a single integrated service offering with seven main service areas: Underground Construction (Untertagebau), Geology/Geotechnics, Natural Hazards Assessment, Water/Energy (hydrogeology), Contaminated Sites/Environment, Mineral Resources, and advanced 3D Modeling Services. The modeling services encompass geomechanical 3D modeling, geological 3D modeling, groundwater modeling, rockfall simulation using RAMMS software, BIM integration, GIS analysis, and geotechnical calculations. These services are delivered through collaborative partnerships, notably with Dr. von Moos AG for modeling engagements. BTG serves public institutions, cantons, municipalities, railway companies, hydropower operators, and private clients primarily in the Swiss cantons of Graubünden, St. Gallen, and Glarus.
