Prona SA

What Prona SA does

Prona Romandie SA is a Swiss multidisciplinary environmental and safety consultancy headquartered in Yverdon-les-Bains, operating across French-speaking Switzerland (Romandie) from three offices (Yverdon-les-Bains, Neuchâtel, Fribourg). The firm delivers mandates, expert assessments, and advisory services across 12 specialized domains: acoustics/noise/vibrations, environmental consulting, fire protection, waste and building pollutants, environmental impact assessments (EIE) and monitoring (SER), water management and protection, nature and landscape, building physics, soil protection, workplace safety, GIS, and contaminated site investigation. Its technology stack is built on conventional specialist tools — class 1 sound level meters, QGIS, CATT-Acoustic, Feflow hydrogeological modeling, and DJI drones for field surveys — and is differentiated by domain expertise rather than proprietary software. Headcount stands at 27 specialists including EPFL, UniNE, UNIL, and HES-trained engineers, hydrogeologists, biologists, soil scientists, and acoustic experts holding Swiss-specific certifications (STPS, SPSC-SSP, CFST-SSST).

The firm operates a sales-led, project-based professional services model: revenue is generated through customized consulting mandates awarded via direct engagement and tenders from public-sector clients (federal agencies such as OFROU, CFF, and armasuisse; cantonal administrations including DGE Vaud and Service des ponts et chaussées Neuchâtel; and municipalities such as Ville de Neuchâtel, Cornaux, and Cudrefin) and a select set of private-sector clients (notably Nestlé Nespresso and CHUV). Marquee mandates include road-noise cadastres for OFROU, hazardous-substance diagnostics for CFF, deconstruction oversight for armasuisse military facilities, environmental monitoring for Nestlé Nespresso's Avenches site, and acoustic consulting for CHUV's Hôpital des Enfants Lausanne. Pricing is not publicly disclosed and is quote-based per project. Strategic alliances include the Pronaqua joint venture with Aquageo Sàrl for hydrogeological studies, groupement PROAB with Aegerter & Bosshardt for OFROU BAMO noise work, and consortium participation in the PAV Etoile urban development in Geneva, indicating both geographic expansion and bid-capacity amplification through partnerships.

Scale indicators2 records

Recent moves5 records

Expansion highlights6 records

Regional players

• Eichenberger AG: Swiss EHS and environmental consulting firm primarily serving German-speaking Switzerland; comparable multidisciplinary services (EHS, contaminated sites, building physics) and represents a regional competitive benchmark Prona could face when expanding beyond Romandie.

Broad incumbents

• Ramboll: Global environmental, water, and health & safety consultancy with Swiss presence. Overlaps with Prona on EHS, water, contaminated sites, and acoustics but competes as a much larger broad incumbent.
• WSP in Switzerland: Global professional services firm with established Swiss EHS and environmental impact assessment practice competing for federal infrastructure mandates alongside specialty firms like Prona.
• AFRY (formerly Pöyry / AFB): Global engineering and consulting firm with significant Swiss EHS and infrastructure-environment practice. Competes for the same large federal mandates (OFROU, CFF) but operates as a broad incumbent with many additional service lines.

Direct peers

• Stucky SA: Swiss engineering consultancy active in hydraulics, environment, and energy; documented Prona partner for hydraulic/river-revitalization work. Comparable Swiss EHS profile and federal client overlap.
• Holinger AG: Swiss engineering firm specializing in water, environment, and energy consulting with strong hydrogeology and contaminated site practices — directly comparable on Prona's core water management and polluted sites service lines.
• Prona SA (parent entity): Parent/affiliated entity referenced via prona.ch link from Prona Romandie's website. Same brand and service family; relationship not fully defined but operates in the same environmental/safety consulting space in Switzerland.
• BG Ingénieurs Conseils: Swiss multi-disciplinary engineering consultancy offering environment, water, geotechnics, and safety services to public-sector clients across Switzerland including Romandie — comparable scope and customer base to Prona.
• CSD Ingenieurs SA: Swiss environmental, safety, and engineering consultancy with comparable multidisciplinary services (EIE, hydrogeology, contaminated sites, acoustics) and similar mix of public-sector and private clients across Romandie and the rest of Switzerland.
• Aquageo Sàrl: Swiss hydrogeology specialist firm in Prona's Pronaqua joint venture. Directly comparable on groundwater, PACES hydrogeological studies, and tracer test work.
