What Aegerter and Bosshardt does

Aegerter & Bosshardt AG (AEBO) is a Basel-headquartered Swiss civil engineering consulting firm founded in 1947 through the merger of the engineering offices of Dr. Oskar Bosshardt and Gutzwiller & Aegerter. The firm operates a unified engineering bureau organized into seven service areas — Structural Engineering (Ingenieurbau), Railway Construction (Bahnbau), Project and Construction Management, Civil Engineering (Tiefbau) including tunnel and port/water engineering, Fire Protection (Brandschutz) with QSS1-QSS4 quality assurance, Building Preservation and Geomatics, and Traffic and Environment — and serves as a multidisciplinary planning and construction-management partner for major Swiss infrastructure owners. Project mandates are executed using BIM methodology across the project lifecycle (3D modeling, visualization, interdisciplinary coordination, collaboration platforms), supplemented by GIS-based supply/disposal network management and precise geodetic surveying for planning, execution, and operations.

The firm's revenue is generated through professional services billed on a project and mandate basis (hourly rates and fixed fees), driven primarily by direct responses to public tenders from Swiss federal agencies (notably ASTRA for national roads and SBB AG for railways), cantonal building and civil engineering departments, and municipal authorities, with a supplementary portfolio of private commercial and industrial clients (e.g., Rhenus Port Logistics, EuroAirport, Casino-Gesellschaft Basel, EBL, Schweizer Salinen). GTM is sales-led and tender-driven, anchored by 77+ years of continuous Swiss infrastructure track record and embedded in engineering consortia on flagship programs such as the CHF 800M Eppenbergtunnel, CHF 580M Schwamendingen enclosure, CHF 200M+ Waldenburgerbahn renewal, and the BIM-based Vorprojekt of the STEP AS 2030/35 Brüttenertunnel. The company is 100% employee-owned under the AeBo Holding AG structure, with a stated headcount of approximately 100-150 professionals, and is connected to a sister entity AeBo+Dill AG in Sissach. AEBO closed its Laufen branch at end-2024 and its Möhlin branch in February 2025, and on October 14, 2025 it formally simplified its legal name and rebranded under the AEBO identity.
