Quarco

What Quarco does

Quarco is a privately held French collective of 15 specialised structural engineering firms (bureaux d'études structure) headquartered in Saint-Herblain near Nantes, serving enterprises, architects, and project owners across metropolitan France. The collective delivers services spanning structural studies in concrete, wood, metal, and mixed-material construction, structural diagnostics, maîtrise d'œuvre (works execution and construction economics), and assistance à maîtrise d'ouvrage, with a notable proprietary technology — the registered Connecteur Bois-Béton (CBB), described as the only assembly element enabling the combination of concrete floors with vertical wooden frames (MOB, CLT, or laminated wood).

The business model is professional-services based, with revenue generated through project-based quotations for engineering studies, execution works, and turnkey project delivery. Quarco monetises services via a multi-brand portfolio of local agencies (ABAK Ingénierie, 123 Structure, Anjou Structure, Pezzo Ingénierie, GRIF Ingénierie, Exametal, Exetera Ingénierie, YAMO Conseils, Innovons) and, since 2025, a wholly-owned general-contracting subsidiary called Quarco INCORE that bundles conception through delivery under a single interlocutor. The collective sells primarily via direct relationships with clients and partners through its 15 regional offices, supplemented by recruiting events at engineering schools, press releases, and a LinkedIn presence.

Quarco's growth has been fuelled by a roll-up strategy of regional acquisitions (Pezzo Ingénierie 2014, Anjou Structure 2015, GRIF Ingénierie 2020) combined with organic creation of new agencies (ABAK Aquitaine and ABAK Provence in 2018, ABAK Occitanie and Exametal in 2021, ABAK Anglet in 2024, QUARCO Ingénierie Vendée in 2025). The holding structure was formalised in 2023 with the creation of Quarco as the parent of the collective. The company reports that revenue has doubled and headcount has tripled over the past three years, reaching more than 110 collaborators across 15 agencies, with a partnership signed with ETIK Assurance in mid-2025 to embed construction-insurance subscription in the customer journey.
