Perret-Gentil

What Perret-Gentil does

Perret-Gentil SA is a Swiss civil and structural engineering consultancy headquartered in Yverdon-les-Bains with a branch office in Lausanne, serving clients across the French-speaking Swiss Romande region (primarily Vaud, Geneva, and Neuchâtel cantons). The firm traces its origins to Bureau R. Curchod & Cie (1938), was reorganized as Perret-Gentil + Rey & Associés SA in 1974, and adopted its current legal name on January 1, 2020, alongside construction of a new headquarters building at the Y-Parc technology park. The company is privately held by a management-shareholder group and operates with 11–50 employees across engineering, drafting, administrative, and apprenticeship roles.

The company's service portfolio spans six core lines: Structures et bâtiments (structural engineering for buildings), Complexes de production (industrial facilities such as cement, pharmaceutical, food, and wastewater treatment plants), Ouvrages d'art (bridges and artistic structures, including the Europe-first eco-steel Passerelle des Cigarières), Infrastructures de transport (rail and road, notably CFF and TRAVYS mandates), Aménagements publics (parks, squares, cycling lanes), and Etudes particulières (structural assessments, damage investigations, seismic verification). All work follows SIA (Société suisse des ingénieurs et des architectes) standards, particularly SIA 103 across the full project lifecycle from preliminary studies to construction supervision. Differentiated technical capabilities include execution of complex civil works under live railway conditions (including night works and OCP weekend interventions), seismic analysis and retrofitting, and complex geotechnical works (piles, diaphragm walls, underpinning).

Commercially, Perret-Gentil generates revenue through professional services fees on a project-by-project basis, secured via public tenders (appels d'offres) with government clients and direct mandates from established relationships. The customer base is anchored by public-sector clients — CFF SA (Swiss Federal Railways), TRAVYS SA, État de Vaud (DGMR), Ville d'Yverdon-les-Bains, and Commune de Renens — supplemented by private developers and industrial operators including JPF Entreprise Générale, Realstone, Mikron SA, Romande Energie, and Holcim Suisse. The firm is ISO 9001, IQNet, EcoEntreprise, and Entreprise formatrice certified, and distributes its services through a direct sales model supported by its corporate website and LinkedIn presence.

Direct peers

• Henz & Partner AG: Swiss structural engineering consultancy with offices in Zurich and Lausanne. Comparable as a Western Switzerland-based competitor pursuing similar building, bridge and infrastructure mandates under SIA standards.
• Emch+Berger Gruppe: Established Swiss civil and structural engineering group with offices across Switzerland. Directly comparable on municipal, cantonal and CFF infrastructure mandates and operates with a similar consulting-led model serving public and private clients in Western Switzerland.
• Bänziger Partner AG: Swiss structural engineering firm active in building and bridge design across German- and French-speaking Switzerland. Comparable as a Swiss boutique structural consultancy winning similar public-tender and developer-led mandates.
• Dr. Lüchinger + Meyer Bauingenieure AG: Swiss structural engineering consultancy based in Zurich/Aargau, active in bridge, building and transport infrastructure projects. Comparable because it pursues similar SIA-compliant structural and civil engineering mandates for public and private clients.
• Timbatec Holzbauingenieure Schweiz AG: Swiss timber and hybrid structural engineering consultancy active in sustainable building design. Comparable because it operates in the same Swiss structural-engineering niche, with overlapping expertise in timber construction referenced in Perret-Gentil's technology stack.
• Conzett Bronzini Partner AG: Graubünden-based Swiss structural engineering firm with strong bridge and heritage-structure portfolio. Directly comparable as a boutique Swiss structural consultancy taking on complex Ouvrages d'art mandates similar to Perret-Gentil's Cigarières footbridge.
• WaltGalmarini AG: Swiss structural and civil engineering consultancy specializing in complex structures, bridges and transport infrastructure. Closely comparable in service mix (Ouvrages d'art, structures, transport) and in public-sector client base.

Broad incumbents

• Basler & Hofmann AG: Large Swiss engineering consultancy offering civil, structural, environmental and rail-infrastructure engineering across Switzerland. Comparable because it competes with Perret-Gentil on public infrastructure and railway mandates (e.g., CFF), but with a much broader service portfolio and headcount.
• Bollinger + Grohmann AG: European structural engineering consultancy with Swiss presence (Zurich). Comparable on complex building and bridge structural engineering, but with a much broader international footprint and larger bench than Perret-Gentil.

Regional players

• Schlaich Bergermann Partner (sbp): German-based but internationally active structural engineering firm with experience in Swiss bridges and lightweight structures. Comparable on artistic bridge (Ouvrages d'art) work and on complex railway-adjacent infrastructure design.
