AS-Surveyor

What AS-Surveyor does

AS-Surveyor (legal and operating name: AS-Géomètre) is a Nantes-based Géomètre-Expert DPLG surveying practice offering certified land surveying, property measurement, and legal property-organization services in France. Its core specialization is Copropriété & Division en volumes — the technical and legislative documentation of multi-owner property structures under the Mode d'Organisation Immobilière framework — supplemented by Expertise Foncière (boundary demarcation, mitoyenneté, parcel division), Topographie (planimetric and altimetric surveys), certified surface attestations (loi Carrez, surface habitable, surface de plancher, SHO), and architectural plans (1/50–1/100 scale, elevations, sections, and 3D visualization under AutoCAD). The firm serves a mix of B2C individual property owners, buyers, and tenants, and B2B clients including architects, notaries, syndics, developers, and construction firms.

The underlying technology is conventional land-surveying practice — GPS/GNSS georeferencing and digital mapping, with glossary-level familiarity with drone and scanner photogrammetry and AutoCAD-based 3D drafting. The differentiation is not technological but professional and regulatory: the Géomètre-Expert Foncier DPLG credential is a legally regulated designation in France, and only certified holders can perform legally binding bornage (boundary establishment) and certain property-division documentation. Owner Alexandre-Henri Sonneville brings roughly 20 years of experience specialized in ultra-urban expertise, property valuation, and the legislative aspects of copropriété.

The business model is professional services delivered on a quote-based, pay-as-you-go basis; pricing is not publicly disclosed and engagements are one-time certifications or project-based mandates tied to property transactions, construction, renovation, and legal proceedings. Go-to-market is sales-led and direct: a professional website (asgeometre.fr) with educational blog/jurisprudence content, LinkedIn and Facebook presence, phone/email, by-appointment office visits in Nantes, and B2B professional referral relationships with architects, notaries, and developers. Operations are single-office and geographically concentrated in the Nantes metropolitan area.

Broad incumbents

• CBRE France: CBRE is one of the largest global commercial real estate services firms with a substantial French valuation and advisory practice. Its property valuation/appraisal services overlap with AS-Géomètre's Carrez, surface attestation, and condominium-pricing engagements, although CBRE France operates at much broader scale and is not specialized in regulated DPLG surveying.
• BNP Paribas Real Estate: BNP Paribas Real Estate is the real estate arm of BNP Paribas, providing valuation, advisory, and property management across France. It is a broad incumbent comparable on the valuation/appraisal dimension of AS-Géomètre's work, though it does not deliver regulated land surveying or condominium-organization services directly.
• Egis: Egis is a major French engineering and infrastructure consultancy with surveying, geodesy, and land-expertise capabilities supporting transport, energy, and urban development projects. It is comparable as a broader incumbent providing some of the same topographic, cadastral, and infrastructure-related surveying work that AS-Géomètre delivers for clients such as SNCF, GRTgaz, and renewable-energy operators.
• JLL France: JLL is a global real estate services firm offering valuation, capital markets, and advisory in France. It is comparable as a broad incumbent with property valuation capabilities that partially overlap AS-Géomètre's measurement and appraisal work, but JLL France does not specialize in the regulated DPLG surveying and condominium-organization niche.
• Knight Frank France: Knight Frank is a global real estate advisory firm active in France through valuation, capital markets, and consultancy. It overlaps with AS-Géomètre on the property valuation side but is positioned as a broad incumbent serving commercial real estate clients rather than a residential surveying specialist.

Direct peers

• Geofit Group: Geofit Group is one of the largest French land surveying and geomatics firms, offering topographic, cadastral, infrastructure, and 3D/BIM services across France. Direct comparison to AS-Géomètre because both deliver land surveying, cadastral/parcels division, topography, and 3D plans to real estate, infrastructure, and public-sector clients, although at materially larger scale and national scope.
• GEOSAT: GEOSAT is a French surveying and geomatics firm combining land surveying, drone-based acquisition, and 3D modeling for construction, infrastructure, and real estate clients. Direct peer because it competes for the same topographic, boundary, and 3D visualization engagements that AS-Géomètre delivers in the Nantes and broader Pays de la Loire market.

Others

• Sogelink: Sogelink is a French software and data provider for cadastral, surveying, DT/DICT network, and construction workflows. It is included as an ecosystem supplier rather than a competitor: AS-Géomètre practitioners use Sogelink-type tooling for DICT responses, cadastral references, and field-data workflows that support its surveying engagements.
