What CET Ingenierie does

CET Ingénierie is one of France's largest independent engineering firms specializing in Tous Corps d'État (TCE) building engineering. Founded in 1964 and headquartered in Clichy, the firm employs 210 collaborators across eight French offices and delivers integrated multidisciplinary engineering across structural, HVAC/fluids, electrical, BIM, and construction economics disciplines. The company serves both public-sector clients (regions, municipalities, hospital authorities, cultural institutions) and private developers (social housing operators, real estate promoters, logistics firms) across nine end-markets including housing, education, healthcare, sports, culture, logistics, tertiary, urban development, and hospitality.

The firm's core technology is BIM (Building Information Modeling), deployed firm-wide for over 10 years across conception, 3D synthesis, BIM management, and commissioning. Differentiated proprietary capabilities include the Expertise Patrimoniale maintenance control methodology (originated in 1985 by founder Christian Curret, derived from Integrated Logistics Support concepts), and a Suivi des Consommations Énergétiques service line covering thermal diagnostics, DPE, thermography, and IPMVP-based measurement and verification. Certified delivery on HQE, BEPOS, BBC, BREEAM, LEED Platinum, BBCA, Biodivercity, and R2S standards across multiple landmark projects provides third-party credibility.

The business model is professional services fee-for-engagement, with revenues earned through competitive tenders, multi-year framework agreements, and direct negotiation. Reported turnover is €125 million over the last five years (implying ~€25 million annually), with €4 billion equivalent in cumulative project volume and €800 million of construction value delivered per year covering 360,000 m² built or rehabilitated annually. The company operates an integrated ecosystem of eight wholly-owned subsidiaries and partners (GAYA for sustainable development, SETU for VRD infrastructure, Endroits En Vert for landscape design, SERO and SOBRETEC for regional coverage) enabling single-source project delivery. Go-to-market is direct enterprise sales targeting public procurement and private developers, with brand presence through the corporate website, LinkedIn, and industry awards including Green Solutions Awards recognitions.

It competes with CET Ingénierie on large sustainable construction and urban development projects, particularly those requiring international certifications and multi-country delivery.
• Egis: Egis is a major French engineering group covering buildings, transport, urban development, energy, and environment. Its building engineering practice competes directly with CET Ingénierie's TCE mandates, but Egis adds broader infrastructure and international capabilities.
• Artelia: Artelia is a leading French multidisciplinary engineering and project management group operating across building, infrastructure, water, energy, and industry. It is one of the largest independent engineering firms in France with scale and international reach beyond CET Ingénierie's building-focused TCE practice, making it a direct competitor for large public and private mandates.
• Suez Consulting (now part of Artelia): Suez Consulting provided water, environment, and infrastructure engineering services overlapping with CET Ingénierie's urban development and VRD practice; it has been integrated into Artelia, indicating consolidation pressure in the French BET market.
