What Sit&a Conseil does

Sit&A Conseil (SELARL SIT&A CONSEIL, formerly IDTP) is a privately held French surveying and urban planning firm structured as a SELARL with €400,000 in share capital. The company operates through three agencies in La Rochelle (Dompierre-sur-Mer), Niort, and Nantes (Rezé), serving clients across the Nouvelle-Aquitaine and Pays de la Loire regions. It is organized around two service divisions: a Bureau d'études offering new neighborhood creation, environmental and urban development studies, public space development, and landscape architecture; and a Géomètre-Expert division delivering property demarcation (bornage), condominium (copropriété) services, building surveys with 3D modeling, and topographic and network-detection surveys.

The firm differentiates on technical equipment, operating 7 LEICA TCRP1205+ robotized laser total stations, 2 LEICA TCP1205 units, 1 TRIMBLE S5, a LEICA DNA 03 digital level, two Geoslam 3D scanners (Zeb-Revo and Horizon), a Trimble TX7 scanner, and drone-based aerial surveying capability. Network detection operations are certified by Bureau VERITAS under AFNOR NF S70-003, with technicians receiving annual national-committee competency attestations. A multidisciplinary team of approximately 40 staff executes integrated surveying, urban planning, hydraulic, environmental, landscape, and VRD engineering assignments, typically without third-party subcontracting.

The business model is project-based professional services revenue, with pricing delivered via custom quotes rather than published rates. Client acquisition combines direct relationships, referrals, an institutionalized public procurement/tender response function, and a website portfolio of case studies; the firm also operates a dedicated digital client portal (sitea-conseil.com). Customer segments include local governments, real estate developers (Bouygues Immobilier, Marignan Immobilier, TERRALOIRE), infrastructure operators (SNCF, SYSTRA/KEOLIS LILLE METROPOLE), financial institutions (Banque Populaire), and NGOs (Habitat et Humanisme). Leadership comprises Philippe Pacaud as Président and Damien Therry as Directeur Général.
