What barrere does

Cabinet Barrere-Dufau Géomètres - Experts is a French licensed surveying practice operating as a SARL with €150,000 of registered capital, headquartered in Saint-Cloud with a second office in Rueil-Malmaison. The firm provides integrated professional services across four domains: Copropriété (condominium management including modifications, divisions, audits and ELAN-law compliance), Topographie (topographic plans, 3D surveys, GPS measurements, architectural and interior plans), Foncier (boundary demarcation, land divisions, volumetric studies and feasibility analysis) and Diagnostics Immobiliers (Carrez, asbestos, termite, lead, electrical, gas and energy performance diagnostics). The current entity was incorporated in 1997 under Ordre des Géomètres-Experts registration n°1997 B2 00008 and operates from inherited archives of six predecessor surveying practices dating back to 1890.

The firm's underlying technology relies on conventional 3D measurement, GPS instrumentation and RGF93-NGF georeferencing rather than proprietary software or AI-driven tooling. The business model is project-based and quote-driven, with revenue generated per engagement across a fragmented customer base of condominium syndicates, architects, construction professionals, landowners, developers and real estate transactors across the Hauts-de-Seine, Paris and Yvelines departments. The two named partners — Bernard Barrere (Rueil-Malmaison) and Olivier Dufau (Saint-Cloud) — operate the practice alongside an undisclosed number of licensed surveyors and technical staff, with no external investors, subsidiaries, M&A activity or public funding disclosed.

A notable credential is the firm's commissioning by the International Olympic Committee to certify the Paris 2024 Olympic swimming pool to FINA specifications, validating each world record set during the Games. The firm has also publicly aligned itself with the Ordre des Géomètres-Experts' Zéro Artificialisation Nette initiative under France's Climate and Resilience Law, signalling positioning for regulatory-driven demand in land-use reclassification. Distribution is direct, via two physical offices, phone/email contact, website project submission forms, LinkedIn, and professional referrals through the Ordre membership network.

Core offering

Cabinet Barrere-Dufau is a licensed French surveying firm (Géomètres-Experts) that delivers integrated professional services across four pillars: Copropriété (condominium rules, descriptive status of division, splits, advisory), Topographie (topographic plans, 3D surveys, GPS measurements, architectural and interior plans, site implementation), Foncier (boundary demarcation, land divisions, project studies, volumetric analysis), and Diagnostics Immobiliers (Carrez surface, asbestos, termites, electrical/gas, lead, and energy performance diagnostics). The firm serves clients across Hauts-de-Seine, Paris, and Yvelines from offices in Rueil-Malmaison and Saint-Cloud.

Product overview

Cabinet Barrere-Dufau is a surveying and expert firm providing integrated professional services across four core areas: Copropriété (condominium management), Topographie (topography and land surveying), Foncier (land and property management), and Diagnostics Immobiliers (property diagnostics). The firm operates as a unified service practice rather than a software platform, offering specialized sub-services including modified condominium plans, topographic and interior plans, boundary demarcations, land divisions, volumetric studies, and comprehensive property diagnostics (Carrez, asbestos, termites, electrical/gas installations, lead, energy performance).

Direct peers

• Geofit: Geofit is a French surveying and geomatic engineering firm (subsidiary of Bureau Veritas) offering land surveying, 3D measurement, GIS and topographic services across France. It is the most directly comparable scale peer in the same regulatory and service-line space as Barrere-Dufau.

Broad incumbents

• Egis: Egis is a major French engineering group whose Foncier Experts subsidiary delivers surveying, land and property services. It competes for the same French surveying and land-management engagements as Barrere-Dufau but as part of a much broader infrastructure and engineering portfolio.
• Setec: Setec is a large French engineering group whose activities include land surveying, topography and urban planning studies through its subsidiaries. It overlaps with Barrere-Dufau on surveying and urbanisme work but operates at significantly larger scale and broader scope.
• Bureau Veritas: Bureau Veritas is a global testing, inspection and certification (TIC) group whose Geofit subsidiary makes it a direct surveying competitor in France. Its broader TIC scale and capital base give it materially greater capacity than Barrere-Dufau on multi-site and international engagements.

Others

• Sogelink: Sogelink provides digital land, building and permit information software used by surveyors, notaires and property professionals in France. It is an adjacent ecosystem player whose tools are increasingly adopted by surveying firms, including potentially Barrere-Dufau's client base.
