E3 ECONOMIE

What E3 ECONOMIE does

E3 ECONOMIE is a privately held French construction economics and project management consultancy (Bureau d'étude en Économie de la Construction et en Pilotage de Chantier) headquartered in Strasbourg. Founded in 1981, the firm operates with approximately 9-11 employees under founder-Gérant Frédéric Weber and Cadre Associé Régis Vogt, who oversees the OPC pole. The company delivers two integrated service lines: Économie de la Construction — economic evaluation and financial viability assessment of construction projects — and OPC (Ordonnancement Pilotage de Chantier), which covers construction scheduling, cost control, and quality coordination. Engagements span cultural facilities, educational buildings, sports and aquatic infrastructure, social housing and ecoquartier developments, healthcare/EHPAD facilities, municipal government buildings, automotive dealerships, and hospitality projects, with construction values ranging from roughly €1.6M to €34M.

The business is structured around long-standing collaborative partnerships with architectural firms — primarily Agence COULON et Associés, WEBER & KEILING, Paul LE QUERNEC, and LACOMO — which serve as the principal project origination channel. E3 Economie works directly with maîtres d'ouvrage (property developers) and public administrations, securing mandates through direct relationships and public tender processes. Pricing is project-specific, tied to scope, surface area, and complexity, with no publicly disclosed rate cards.

Customer mix is balanced between public-sector municipalities and intercommunalities (e.g., Ville de Mulhouse, Ville de Pélissanne, Ville de Cagnes-sur-Mer, Thionville Municipality) and private-sector developers/operators (Nexity, Bouygues Immobilier, DOMIAL, CUS Habitat, Mercedes-Benz dealerships). Operating geographies extend from the Grand Est stronghold into Bourgogne-Franche-Comté, Île-de-France, Normandie, Provence-Alpes-Côte d'Azur, and Auvergne-Rhône-Alpes, sourced primarily through the architectural firm network rather than a dedicated regional sales motion. The company maintains a minimal marketing footprint: a website portfolio showcase and a Facebook page constitute the principal channels, with project referrals from architectural partners driving the mid-funnel pipeline. No external funding, no AI/technology stack, no patents, and no subsidiary structure are indicated.
