What Quarta does

Quarta is a French certified surveying and geomatics firm (Géomètre-Expert) headquartered in Saint-Jacques-de-la-Lande near Rennes, founded in 1982 and operating 20 agencies across Brittany, Loire-Atlantique, Île-de-France, and Montpellier. The company provides multidisciplinary geospatial and land management services organized into three core divisions: Topographie (2D/3D surveying, precision measurement, network detection, bathymetric surveys, and 24/7 structural monitoring), Géomètre-Expert (legal land delimitation, property division, condominium management, CAD/SIG, and ingiénierie foncière including mass landowner notifications), and Aménagement (VRD project management, ecological engineering, regulatory and operational urban planning, landscape design, and environmental/hydraulics services). Quarta operates with 215 collaborators, including 15 certified Géomètres-Experts, using static and dynamic scanners, airborne LIDAR, terrestrial and drone photogrammetry, single and multi-beam echo sounders, electromagnetic detectors, and ground-penetrating radar. The company also develops custom WebSIG/GIS platforms hosted for clients and maintains decades of archival land records (40-70+ years at multiple offices).

Quarta's business model is project-based professional services priced via quote-driven engagements (devis), with intermediate invoicing based on project milestones for long-duration mandates. Pricing is not publicly disclosed and an advance payment (acompte) may be required for significant work. The company serves three primary customer segments: individuals (over 2,700 per year) for boundary marking, property division, and floor plans; professionals (real estate, construction, developers, industrials) for topographic surveys, BIM modeling, and property management; and public authorities (municipalities, departments, regions, SEMs such as SEMAPA, and national institutions including Louvre, Sénat, CNRS, SNCF, and Société du Grand Paris) for large-scale topographic surveys, land management, and regulatory compliance. Customer acquisition is driven by local agency presence, direct referrals from notaries, architects, and municipalities, and public procurement processes. The company holds ISO 9001 certification and is identified as a Marque Bretagne brand. Geographic expansion has been steady but incremental, with notable 2024 openings of Questembert and Ploërmel agencies in Brittany and the development of renewable energy services through the Montpellier agency. Revenue is not publicly disclosed. Quarta is owned as an independent private company with no external investors or parent organization identified.
