What B+S does

B+S AG is a privately held Swiss engineering and planning firm founded in 1997 and headquartered in Bern, with additional offices in Zürich and Luzern. The company operates across three core business divisions — Verkehrsanlagen (Traffic Infrastructure), Areale und Gebäude (Areas and Buildings), and Umwelt, Energie und Wasser (Environment, Energy and Water) — delivering comprehensive planner and engineer services in approximately 30 specialized technical fields. Its client base is anchored in the Swiss public sector, including federal agencies such as ASTRA (Federal Roads Office) and BBL (Federal Buildings and Logistics), cantonal governments (notably Kanton Luzern), municipalities, and major railway operators including SBB (Swiss Federal Railways) and BLS, with select private-sector engagements such as Migros Aare.

The firm's technical backbone is built on Building Information Modeling (BIM) and digital planning methodologies applied across the project lifecycle. Notable capabilities include a dedicated BIM management and overall coordination role on complex infrastructure programs, as well as BIM2LCA — a proprietary application integrating BIM models with Life Cycle Assessment (LCA) and CO₂ calculations under the SNBS (Swiss Sustainable Building Standard) Infrastructure framework. These digital tools support sustainability reporting, interoperability across disciplines, and lifecycle evaluation for tunnels, railway stations, highways, and water infrastructure. The firm emphasizes interdisciplinary teams spanning traffic engineering, structural engineering, environmental science, hydrology, and civil/hydraulic engineering.

B+S AG operates a professional services revenue model, earning fees through project-based contracts, framework agreements, and consortium commissions. Go-to-market is concentrated on competitive bidding and long-term direct relationships within Switzerland — notably as a member of multiple engineering consortia (IG) including IG Nuovo Gottardo (Gotthard Second Tube), IG Bahn+ (SBB track renewal framework), IG 3B+ (Gümligen Süd decongestion), IG Bümpliz, and the Planergemeinschaft Generalplaner Bern verbindet. The firm is registered as a Swiss Aktiengesellschaft (AG), is privately held with no disclosed external investors or parent company, and currently employs 251–500 staff. Pricing is not publicly disclosed, consistent with its B2B public-sector contracting model.
