Buhrer + Dallenbach Engineers

What Buhrer + Dallenbach Engineers does

Bühler + Dällenbach Engineers (legal entity b+d ingenieure ag) is a privately-held Swiss civil engineering firm headquartered in Steffisburg with a branch office in Matten-Interlaken, serving the Bernese Oberland region of the Canton of Bern. Founded in 1984 as a partnership and incorporated as an Aktiengesellschaft on 1 January 1999, the firm employs approximately 50 staff and reports annual revenue exceeding CHF 6 million. Its customers span municipal, cantonal, and federal government clients (e.g., Gemeinde Steffisburg, Tiefbauamt des Kantons Bern OIK I, ASTRA, armasuisse, BLS Netz AG) as well as private developers and utilities (e.g., HRS Real Estate, Schilthornbahn AG, Fernwärme Thun AG, NetZulg AG), with a 40-year track record and reference projects ranging from CHF 250,000 to CHF 148 million.

The firm delivers integrated engineering, construction, surveying, and geomatics services organized into twelve service modules: infrastructure/utilities, road/rail construction, urban drainage, hydraulic engineering, special foundation engineering, structural engineering, crack protocols/condition surveys, landfill construction, official surveying (amtliche Vermessung), geomatics, drone surveying, and data/plan ordering. The technology stack is built around established CAD and BIM platforms (AutoCAD, Civil 3D, Revit, BaCAD, cadwork), supplemented by proprietary service capabilities including eBee drone photogrammetry for terrain and landfill surveys, automated geodetic monitoring systems (tachymeters with 300+ measurement points in the Allmendtunnel Thun), and an automated track-monitoring system used during live railway construction (deployed on BLS station Kirchberg-Alchenflüh and Münsingen ESN). The firm also holds the appointed Nachführungsgeometerbüro mandate for 12 municipalities, providing recurring official cadastral surveying services.

Revenue is generated through project-based professional services contracts, with work acquired via public tenders (municipal, cantonal, federal) and direct engagement with private developers and utilities. The go-to-market is sales-led and relationship-driven, reinforced by long-tenured project alliances (Ingenieurgemeinschaften) with peer firms such as Emch + Berger AG Bern and B+S Ingenieure AG, plus sub-consultant roles on flagship regional projects (ASTRA Allmendtunnel, Schilthornbahn 20XX). Distribution is direct, with delivery executed by in-house engineering teams across the two office locations; digital channels (company website, LinkedIn, YouTube, Instagram) and an online portal for appointment booking and plan/data ordering support mid-funnel engagement. The business model combines lumpy project revenue with a more predictable base from official surveying mandates and ongoing framework relationships with regional authorities.
