Garcia Ingénierie

What Garcia Ingénierie does

Garcia Ingénierie (G2i) is a privately held, family-owned technical building engineering consultancy headquartered in Marseille, France, founded in September 1980 by Francis Garcia. The firm delivers fluid and electrical engineering for complex buildings across four service lines — Optimiser (energy audits under NF EN 16247, Tertiary Decree compliance, energy management), Concevoir (HVAC/CVCPB, electrical CFO/CFA, fire safety SSI/CSSI, BIM Levels II and III, renewable integration), Piloter (Direction de l'Exécution des Travaux, visa validation, GPA follow-up), and Exploiter (commissioning and GTB optimization). It holds deep certification credentials across HQE, BREEAM (Good to Excellent), BDM (Bronze to Gold), NF Habitat, E+C-, BBC, THPE, and RT2012/RE2020, and is recognized for pioneering thermal-energy work including the largest private thermal loop in Europe at the Stade Vélodrome.

The company operates a professional-services, project-fee model with no public pricing list, securing work through competitive public tenders (marchés publics) and direct negotiation with private developers. Revenue is generated via engineering studies (ESQ, AVP, PRO, DCE phases), construction supervision (DET/ART), energy audits, AMO/owner assistance, and post-delivery commissioning, on projects whose total construction values span roughly €1M to €600M. Customer segments are weighted toward French public-sector building owners — municipalities, departments, regions, state agencies — with additional exposure to property developers, healthcare operators, hoteliers, sports and cultural institutions. Documented reference clients include Ville de Marseille, Conseil Départemental du Var, Région SUD, Institut Paoli-Calmettes, MuCEM (Ministère de la Culture), Constructa Urban Systems / Les Docks, Pitch Promotion, Hampton by Hilton, Zinedine Zidane (5ZS), and Hôtel Meininger. Industry estimates place headcount in the 60-80 range against a firmographic band of 11-50, with active recruitment for BIM modelers, project managers, and energy-efficiency engineers.

Distribution is direct enterprise field sales augmented by three structural alliances: co-founding membership in the Alliance Ingénierie national network (referral and co-bidding reach), a long-standing co-bidding partnership with R2M on flagship tenders, and the firm's role co-founding ENOV (École Nouvelle pour la Maitrise de l'Énergie), which doubles as a talent pipeline. G2i currently sits under second-generation leadership (Olivier Garcia, Président; Delphine Garcia, Directrice Générale) following the integration of a third generation of the founding family into governance in January 2025, with no external shareholders, no disclosed funding rounds, and no M&A activity in the source material.
