Gaxieu

What Gaxieu does

Gaxieu (legal name Cabinet d'études RENE GAXIEU) is an independent French engineering consultancy founded in 1972 and headquartered in Béziers, with eleven regional offices distributed across seven departments of the Occitanie Pyrénées-Méditerranée region (Aude, Gard, Hérault, Lozère, Pyrénées-Orientales, Tarn, and Vaucluse). The firm provides multidisciplinary infrastructure consulting services to local authorities — municipalities, intercommunalités, and other public bodies — alongside a secondary private-sector client base. Nine interconnected competency areas span Assistance à Maîtrise d'Ouvrage (AMO), urban development and VRD, hydraulic/port/fluvial works, water storage and treatment including REUT (reuse of treated wastewater), natural risk prevention, waste management, energy (notably wind farms), urban planning, and SIG-BIM 3D visualization. Government-approved certification for hydraulic infrastructure safety (dikes and small dams, valid through 2026) and OPQIBI engineering qualification underpin eligibility for regulated public-sector mandates.

Underlying technology consists of engineering consulting workflows supported by Geographic Information Systems (SIG), Building Information Modeling (BIM), 3D project visualization, and hydraulic modeling for watercourse and watershed analysis. These tools enable integration of projects into site environments before construction and assessment of the impact of existing or planned hydraulic structures on flow conditions. Solutions are delivered across the full project lifecycle — from conception through completion — including feasibility studies, regulatory documents, project management, construction monitoring, and diagnostics.

Gaxieu's business model is project-based professional services: revenue is generated through consulting fees quoted per project according to scope and complexity, with no publicly disclosed pricing. The go-to-market is sales-led and relationship-based, anchored by the 11-agency regional footprint that enables direct engagement with local government clients across Occitanie. Christian Faroux serves as President. Marketing is conducted through industry events (Cycl'Eau, Salon des Communes), professional associations (Fédération Cinov, Aqua Valley, BuildingSmart France, Coq Vert), and the company website. All named customers — including Le Grand Narbonne, Carcassonne Agglo, Commune de Fleury d'Aude, Agglomération Béziers Méditerranée, SIVU Pays d'accueil Vallée du Lot, and Ville de Béziers — are local-authority clients.
