Geo Bretagne Sud

What Geo Bretagne Sud does

Geo Bretagne Sud (GBS) is a regulated French land surveying and territorial development firm headquartered in Vannes, Morbihan, Brittany. Founded in its current form in 2000 from the legacy cabinet JOSSO (dating to 1969) and absorbing predecessor firms including cabinet COUËDEL (1955), the company operates as a Société d'Exercice Libéral par Actions Simplifiée (SELARL) of Géomètres-Experts registered with the Ordre des Géomètres-Experts. GBS serves local authorities (collectivités), private landowners, developers, architects, engineering firms, and coastal leisure operators across the Morbihan department through four agency offices in Vannes, Muzillac, Sarzeau, and Plouharnel, with a team of approximately 50 multidisciplinary professionals.

GBS delivers five integrated service lines: Géomètre-Expert legal advisory (boundary demarcation, parcel division, servitudes, cadastral management), VRD engineering and project management (roads, utilities, public spaces), topographic surveying and 3D modelling (using Leica RTC360, BLK360, and FARO ORBIS laser scanners processed through Cyclone, Revit, and ArchiCAD), urban and environmental studies, and landscape design. Its wholly-owned subsidiary EOL (founded 2010) extends capabilities into regulatory urban planning, hydrology, and environmental compliance, particularly for coastal and rural development projects under French Littoral law. The technology stack centres on precision geomatic instrumentation rather than software platforms, with workflow integration from field data capture to BIM-compatible deliverables.

Revenue is generated on a project-based professional services model with quotes provided per engagement and no publicly disclosed pricing. With reported revenue exceeding €4 million as of 2024, the company produces more than 1,500 person-days of topographic survey work annually and derives income from public infrastructure contracts (e.g., the Sarzeau soft mobility tunnel under the RD780), private property transactions, and regulatory urban planning engagements. As of January 2025, GBS and EOL operate as subsidiaries of the GEOFIT Group while retaining independent branding and management under Emmanuel Hallay and Alain Riou, accessing GEOFIT's broader 3D modelling and dynamic cartography capabilities in exchange for a strengthened regional platform in Grand-Ouest France.
