What Gaehler and Partners does

Gaehler and Partners (legal entity: Gähler und Partner AG) is a privately held Swiss architecture and civil engineering firm headquartered in Ennetbaden, with a branch office in Bern. Founded in 1988, the firm employs 51-100 staff organized into three divisions: Hochbau (building construction, covering architecture, structural engineering, and building technology); Consulting (project management and real estate development); and Infrastruktur (traffic construction, underground/tunnel construction, and traffic engineering). It serves primarily Swiss cantonal, municipal and federal public-sector clients — including ASTRA (the Federal Roads Office), BLS AG rail, and municipalities such as Wettswil a.A. and Wohlen — alongside private developers and industrial clients, delivering services across the full construction value chain as a general planner.

The firm's core technology stack is centered on Building Information Modeling (BIM) used as an integrated methodology across all disciplines, supported by CAD for technical drawings and digital 3D models that produce a common data basis for planning, coordination, and feasibility simulation. ISO 9001 certification has been continuously maintained since 1995, and BIM is positioned as a quality-assurance and coordination layer that reduces interface losses across architectural, structural, building-technology, and infrastructure teams. The company also operates the GP Academy for internal project-manager training and an apprenticeship pipeline for technical roles including Draftsperson EFZ, Building Technology Planner EFZ, and Electrical Planner EFZ.

Revenue is generated through project-based professional-services fees derived from general-planner mandates and discrete planning commissions, acquired via competitive project tenders, direct commissions, and consortium or project-alliance structures. The firm participates in joint engineering ventures (e.g., Ingenieurgemeinschaft Ligerz with Stucky SA and Gruner SA) and project alliances (e.g., BLS AG alliance GHT). No public pricing, revenue figures, or external investment are disclosed; ownership is independent with no evidence of private equity, parent company, or external funding involvement.

Broad incumbents

• Arcadis: Global design, engineering, and consulting firm with Swiss presence. Comparable in competing for ASTRA and large cantonal infrastructure mandates, though Arcadis serves a much broader portfolio across multiple continents.
• WSP Global: Global engineering and professional services firm with substantial Swiss operations. Comparable as a competitor for major federal infrastructure tenders (tunnels, roads), but operates at far greater scale across multiple geographies and end markets.

Direct peers

• Emch+Berger: Swiss engineering consultancy active in structural, civil, and environmental engineering with strong public-sector infrastructure exposure. Comparable service mix and Swiss market overlap with GPAG.
• WaltGalmarini AG: Zurich-based engineering firm with strong infrastructure, tunneling, and structural expertise. Competes with GPAG for similar Swiss infrastructure mandates and is a comparable regional specialist.
• Basler & Hofmann: Swiss engineering and planning firm providing integrated services across buildings, infrastructure, and environment. Closely comparable to GPAG in multi-disciplinary general planning for Swiss public clients.
• Gruner SA: Swiss engineering firm covering structural, civil, geotechnical, and infrastructure work. Directly comparable — competes for the same public sector infrastructure mandates and partners with GPAG in the Ligerz tunnel consortium.
• AF Toscano AG: Swiss architecture and engineering firm providing integrated building and infrastructure planning services. Comparable in offering a general-planner model serving Swiss cantonal and federal clients.
• Stucky SA: Swiss engineering consultancy with strong tunneling, hydraulics, and infrastructure practice. Directly comparable to GPAG as a co-member of the Ingenieurgemeinschaft Ligerz consortium, serving overlapping federal and cantonal infrastructure clients in Switzerland.

Emerging players

• Hunziker Betatech AG: Swiss engineering firm focused on infrastructure, water, and environment. Comparable in serving Swiss public infrastructure clients with overlapping traffic/road engineering services, though with a smaller building-construction footprint than GPAG.

Regional players

• Schmid + Pletscher AG: Swiss engineering and planning firm with structural, civil, and infrastructure expertise. Comparable in service profile and regional market overlap, particularly across northern and eastern Swiss cantons.
