GTA Géomètres Experts

What GTA Géomètres Experts does

GTA Géomètres Experts is a Paris-based regulated professional surveying firm (Société d'exercice libérale par actions simplifiée) with a 65-year operating history, employing approximately 60 collaborators in the Île-de-France region. The firm operates under French statute as a registered cabinet of géomètres-experts (Ordre registration 1990B100001), delivering legally binding land surveying and property services. It is the surveying core of a broader GTA group that also includes engineering (GTA Energies), environmental consultancy (GTA Environnement), shared services (GTA Supports GIE), a digital infrastructure platform (Villes et Réseaux 3D), and a 3D studio (Volumetric Studio).

The firm delivers five integrated service lines: legal and land services (boundary demarcation, property titling, volume division, ASL/AFUL setup); topography (polygon networks, GPS referencing, drone surveys, construction implantation, structural monitoring); architecture and BIM (laser scanning, BIM Levels 1–3 with IFC/OpenBIM interoperability, heritage documentation, GIS systems and digital twins); condominium services (lot division, VEFA, split management); and real estate intermediation and surface certifications (Carrez, habitable, GLA, RICS-compliant valuations). Underlying technology includes FARO S150 laser scanners, DJI Phantom 4 RTK drones for photogrammetry, NavVis mobile dynamic scanners for rapid 2D/3D capture, and standard CAD/BIM toolchains (AUTOCAD, COVADIS, REALWORKS/SCENE, REVIT).

Revenue is generated through project-based professional services fees, quoted per engagement scope and contracted over multi-year durations with enterprise and government clients. Customer mix spans major construction firms (Bouygues, Vinci, Eiffage), public sector and transportation authorities (Ville de Paris, RATP, SNCF Réseau, IDF Mobilités, EPA Orly Rungis), real estate operators (CDC Habitat, SNCF Immobilier, Covivio), and corporate accounts (AXA, Carrefour, Sanofi). Go-to-market relies on direct field sales, professional referrals, and institutional positioning through Ordre, UNGE, FENGS, and RICS memberships. Certifications held include ISO 9001:2015, ISO 45001:2018, and LUCIE 26000 (renewed November 2022).

Core offering

GTA Géomètres Experts is a French regulated professional surveying firm offering legal land services (boundary demarcation, volume division, servitude analysis), topographic surveys, BIM and 3D laser scanning/drone photogrammetry services, condominium division and co-ownership rules, and real estate intermediation with Carrez/GLA surface calculations and RICS-compliant valuations. It serves enterprise and government clients in the Paris region and across France through project-based engagements.

Product overview

GTA Géomètres Experts operates as a unified professional surveying practice offering five interconnected service lines: Juridique & Fonciers (land law, boundary demarcation/bornage, subdivision, and volume division), Topographie (topographic surveys, GPS/GNSS mapping, and construction implantation), Architecture/BIM & Systèmes d'Information (laser scanning, 3D modeling, BIM levels 1–3, GIS systems, and heritage monument documentation), Copropriété (condominium division, VEFA, split management, and regulatory documents), and Immobilier & Surfaces (real estate intermediation, surface calculations for legal/regulatory purposes, and property valuation). The practice combines traditional surveying methods with advanced 3D and digital technologies (drones, laser scanning, BIM) delivered through standard CAD/GIS/BIM platforms (AUTOCAD, REVIT, COVADIS, NavVis). The company also publishes a Carbon Balance (Bilan Carbone) as part of its CSR commitments.

Expansion highlights5 records

Direct peers

• Geofit Group: Geofit Group is one of France's largest land surveying and geomatic firms, offering topographic surveys, BIM, 3D scanning, and real estate services. Directly comparable as the most prominent French surveying competitor to GTA across both surveying and digital/BIM service lines.

Broad incumbents

• Egis: Egis is a major French engineering consultancy providing infrastructure, urban planning, and surveying-adjacent services across transport, energy, and buildings. Overlaps with GTA on infrastructure surveying projects (Egis is also a GTA client) but operates at much larger scale across the full project lifecycle.
• Setec: Setec is a leading French engineering group with land surveying, topography, and infrastructure monitoring practices. Competes with GTA on public infrastructure projects and brings integrated engineering capabilities that GTA's standalone surveying model cannot match.
• Artelia: Artelia is a major French engineering and project management consultancy with surveying, BIM, and infrastructure capabilities. Serves similar clients (construction firms, public sector) across France and competes on larger multi-disciplinary mandates.
• Fugro: Fugro is a Dutch global leader in geo-data and surveying services, providing topographic, geotechnical, and remote sensing solutions. Comparable in service portfolio (drone surveys, BIM, structural monitoring) but at global scale across offshore, energy, and infrastructure markets.
• Sweco: Sweco is a Sweden-based European engineering and design consultancy with significant surveying and BIM practices. Comparable in surveying, BIM modeling, and infrastructure project delivery across European markets.
• WSP: WSP is a global engineering consultancy with land surveying, BIM, and infrastructure services across transport, property, and urban development verticals. Competes with GTA for large public and private surveying mandates across Europe.
• AECOM: AECOM is a global infrastructure consulting firm with surveying, GIS, BIM, and asset management practices serving public infrastructure and real estate clients. Overlaps with GTA on major urban infrastructure and transport projects internationally.

Emerging players

• Geosat: Geosat is a French specialist in drone-based surveying, photogrammetry, and 3D modeling services. Comparable on the drone photogrammetry and aerial mapping side of GTA's business, though narrower in scope than GTA's full legal/land surveying practice.

Others

• Sogelink: Sogelink is a French software and data platform provider serving surveying, construction, and public works professionals (including GéoFoncier integration mentioned in GTA's stack). Enables digital workflows for surveyors but does not directly compete on professional services delivery.
