Lamalle Ingenierie

What Lamalle Ingenierie does

Lamalle Ingénierie is a family-owned French structural engineering firm (Bureau d'Études Techniques) founded in 1961 and headquartered in Orly, France. The company delivers structural engineering studies for construction projects in reinforced concrete, steel framing, and timber — covering both new builds and rehabilitation — alongside construction economics consulting (cost estimation and investment evaluation across all construction trades), project management (maîtrise d'oeuvre including design, execution studies, construction supervision, and AMO), and structural diagnostics for existing buildings. It operates through four regional agencies (Orly in Île-de-France, Tours and Chaudon in Centre-Val de Loire, Châtellerault) and serves public institutions, large enterprises, private developers, architects, and individual clients across France.

The business operates as a professional services firm under Ataraxie Groupe, a holding company formed in 2018 that also owns Cojane, a structural diagnostics subsidiary created in 2011. Cojane specializes in building pathology diagnosis, expert assessments following incidents, decennial warranty exits, and legal-support diagnostics delivered in collaboration with construction law attorneys — giving the group integrated structural engineering and diagnostic capabilities. The firm is led by co-gérants Yves Denizet (structural engineering) and Catherine Lamalle (construction economics), with 11 total collaborators connected across agencies via videoconferencing. The company explicitly positions itself as independent from all construction market actors to preserve objectivity on pricing and materials.

The revenue model is project-based professional services priced per engagement according to scope, complexity, and client type, with no publicly disclosed pricing tiers. Distribution is direct-to-client through the agency network, with marketing limited to a portfolio-based website and repeat/referred business from long-tenured clients. Named customers include SANOFI (25-year relationship), Conseil Général du 94 (10 years), and Axis (15 years), alongside other enterprise and public-sector engagements. The firm maintains a deliberately human-scale operation with no external institutional investors or disclosed funding.

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Egis: French-headquartered engineering and consulting group covering buildings, infrastructure, and urban development with structural and project management services. Competes for similar public-sector and large-enterprise engineering mandates at significantly greater scale than Lamalle.
• Setec: Major French engineering group offering structural design, project management, and technical consulting across infrastructure and buildings. Overlaps with Lamalle's core BET services but operates at vastly greater scale (multi-thousand employees) across multiple geographies.
• Artelia: French engineering group offering structural studies, construction economics, and project management across building, infrastructure, and industrial sectors. Closely matches Lamalle's service portfolio (structure + économie de la construction + maîtrise d'oeuvre) but at substantially larger scale.
• Tractebel (Engie Solutions): International engineering consultancy owned by Engie providing structural, civil, and project management services for buildings and infrastructure. Competes for the same large institutional and industrial mandates as Lamalle, with global reach and substantially deeper resources.
• Ginger Group (Ginger CEBTP): French engineering group specializing in geotechnical, structural diagnostics, and construction expertise — directly comparable to the Cojane subsidiary's pathology and diagnostic offering, plus broader structural services that overlap with Lamalle's core BET business.

Others

• SOCOTEC: French leader in testing, inspection, and certification for construction and infrastructure. Adjacent to Lamalle's Cojane diagnostic expertise and competes for technical-control and verification mandates, though its core TIC model differs from Lamalle's design-side BET services.
• Apave: French testing, inspection, and certification group with building, infrastructure, and industrial expertise. Competes for technical-control and diagnostic mandates that overlap with Cojane, and engages in structural assessment work on existing buildings.
• Bureau Veritas: Global testing, inspection, and certification company with a substantial French construction and buildings practice. Adjacent rather than directly competing — its TIC model complements Lamalle's design-side engineering but overlaps on diagnostic, verification, and expert-assessment engagements.
