What COHIN CONSTRUCTION does

COHIN CONSTRUCTION is a French general construction company founded in 2000 and headquartered in Écardenville-sur-Eure, Normandy, operating as a maître d'œuvre (project manager) across Normandy and the Paris region. Since 2010 it has been affiliated with the COHINVEST group, which also encompasses COHIN ENERGY and COHIN ENVIRONNEMENT. The company delivers five core services: industrial maintenance (its original activity, serving clients in automotive, agri-food, pharmaceutical, steel, and environmental sectors), civil engineering and masonry, locksmithing and metalwork, structural reinforcement (including carbon fiber plate installation and intumescent fire protection), and liquid screed application. It combines these into turnkey TCE (Tout Corps d'États / all-trades) solutions for clients, with named enterprise accounts including Sanofi, Renault, VPK Alizay, Veolia Environnement, and Heidelberg Materials.

The company's revenue model is project-based professional services, with quote-based pricing per project and direct enterprise sales as the primary go-to-market motion. Distribution relies on direct B2B outreach, professional networks, and referrals, supported by digital marketing via a LinkedIn page, an Instagram showcase account, and a website with detailed project case studies. Recent operational expansion has extended the service offering beyond traditional construction into renewable energy infrastructure (photovoltaic trackers via OKWIND technology and wooden photovoltaic canopies via Moduland) and wastewater treatment (containerized Waste Water Box stations using the UniBioCell biological process), including an internationally-financed mobile wastewater unit delivered to Ukraine in 2023.

Notable technical capabilities include a specialized carbon-fiber structural reinforcement practice (over 1,200 linear meters installed at Tour Gagarine in Romainville), custom metal fabrication for architectural projects (572 linear meters of steel beams for an artist residence in Romainville), and access to the proprietary UniBioCell biological wastewater treatment process through the COHINVEST ecosystem. The company is privately held under the COHINVEST group with Sébastien Cohin serving as group president, and operates with a headcount in the 11-50 range; revenue is not publicly disclosed.

Broad incumbents

• Bouygues Construction: Major French general contractor offering building, civil works, and energy services. Comparable because both deliver TCE/all-trades construction projects to enterprise and public-sector clients, though Bouygues operates at vastly larger national and international scale.
• Eiffage Construction: Large French construction and concessions group providing building, civil engineering, and energy infrastructure. Overlaps with COHIN's civil engineering, structural reinforcement, and industrial client base across France.
• Vinci Construction: Global French construction leader covering buildings, civil works, and specialized networks. Comparable TCE project delivery to enterprise and government clients, though at much larger scale and geographic reach than COHIN.

Direct peers

• Spie Batignolles: Mid-sized French general contractor delivering multi-trade construction across civil engineering, structural works, and building. Closely comparable TCE service model and enterprise/government client mix to COHIN.
• NGE (Nouvelles Générations d'Entrepreneurs): Independent French multi-specialist contractor active in civil engineering, earthworks, road, pipeline, and building trades. Comparable regional multi-trade delivery model and enterprise/public client base to COHIN.
• Demathieu Bard: Mid-sized French construction group specialized in building, civil engineering, and real estate development. Overlaps with COHIN on structural reinforcement, metalwork, and enterprise/tertiary construction in regional French markets.
• Léon Grosse: Independently owned French general contractor focused on building construction, structural rehabilitation, and heritage restoration. Highly comparable service mix (construction, structural reinforcement, heritage) to COHIN.
• Rabot Dutilleul: Regional French construction group active in building, rehabilitation, and property development across northern France. Comparable regional construction and renovation focus to COHIN's Normandy/Paris territory.
• GCC (Générale de Construction et de Carrières): French construction group specialized in building, civil engineering, and environmental works. Comparable TCE approach and overlap on environmental/utility construction such as COHIN's wastewater treatment projects.

Regional players

• COLAS: Major French/international road construction and civil engineering subsidiary of Bouygues. Comparable civil engineering and infrastructure project execution capabilities, though focused on roadworks rather than building services.
