What Etchart Construction does

Etchart Construction SAS is a privately held French general contractor and design-build provider headquartered in Bayonne, formed in 2016 through the consolidation of five regional construction companies (Alzate, Baron, Coda GC, CTBTP, and Etchart). The company operates across two main divisions, Bâtiment (building) and Génie civil (civil engineering), with specialized market verticals in healthcare facilities, aerospace and defense infrastructure, industrial buildings, environmental and renewable energy civil works, historical monument restoration, and housing rehabilitation. Technical delivery is supported by three internal offices covering structural engineering, construction methods planning, and BIM (Building Information Modeling) coordination from design through execution.

The business model is project-based B2B contracting, with revenue generated from one-time construction contracts awarded through competitive public procurement or direct negotiation with institutional and private clients. Project values range from approximately €85,000 for small restorations to €52 million for major healthcare facilities, with contract structures including lump-sum, cost-plus, and design-build with guaranteed maximum price (GMP). The go-to-market combines a regional agency network of seven offices across Nouvelle-Aquitaine (Bayonne, Irissarry, Pau-Pyrénées, Landes, Bordeaux, Aytré/La Rochelle) with strategic joint ventures on large-scale projects (notably with Eiffage Construction and Fayat).

The company reports €80 million in annual revenue, 230 employees with an average age of 40, and a wholly-owned maritime/fluvial civil engineering subsidiary (EGCM) based near La Rochelle. Recognition includes the BIM d'Argent 2020 award for the Ampéris industrial project and MASE safety management certification. Ownership is held by founding families and management as part of the broader Groupe Etchart, with no external private equity or venture capital backing disclosed.

Direct peers

• Eiffage Construction: Major French general contractor and Etchart's named JV/co-traitance partner on Clinique Croix du Sud (€62M) and BAB2 retail expansion. Equivalent general contracting + design-build model with strong regional agency network, very high direct comparability in scope, mix, and contracting model.
• Fayat: French family-owned multi-trade construction group that is Etchart's co-traitant on the EHPAD Bixta Eder project. Comparable multi-vertical general contracting model (building, civil works, energy), and a closely similar founder-owned, mid-to-large French GC profile.
• Spie Batignolles: French multi-specialist general contractor organized across building, civil engineering, energy, and landscaping. Directly comparable general contracting + design-build delivery model serving public and private enterprise clients with similar sector breadth.
• Bouygues Construction: Construction arm of Bouygues Group, one of France's largest general contractors delivering building, civil engineering, and energy projects. Closest comparable in business model (general contracting + design-build) and customer set (public/private enterprise clients), though operating at materially larger scale and geographic reach than Etchart.
• Léon Grosse: French independent, family-controlled general contractor active nationally across building, heritage restoration, industrial, and complex projects. Closely mirrors Etchart's founder-owned, integrated design-build model with strong technical specialization.
• Rabot Dutilleul Construction: Northern-France-based independent general contractor delivering building, rehabilitation, and design-build projects for public and private clients. Directly comparable in general contracting + design-build delivery, though with a different regional footprint.
• Demathieu Bard: French independent general contractor with diversified building, civil engineering, and infrastructure activity. Equivalent general contracting / design-build model serving regional and national clients, with a similar founder/family governance profile.
• NGE (Nouvelles Générations d'Entrepreneurs): French multi-disciplinary construction group spanning building, civil engineering, road, and environmental infrastructure. Comparable integrated model with multi-regional agency footprint and founder-led, multi-vertical strategy.
• VINCI Construction: France's largest construction group and a global infrastructure player, active across building, civil engineering, and specialized works. Directly comparable general contracting/design-build offering and overlapping end-markets (transport, healthcare, defense, energy), but at vastly greater scale and geographic footprint.

Broad incumbents

• Colas: Bouygues-affiliated French specialist in road construction and civil engineering infrastructure. Overlaps with Etchart's civil engineering and infrastructure exposure but is specialized in transportation infrastructure rather than buildings; included as a broad incumbent/adjacent peer in the French construction landscape.
