ERIBOIS & STRUCTURES

What ERIBOIS & STRUCTURES does

ERIBOIS & STRUCTURES is a French Bureau d'Etudes Techniques (technical engineering consultancy) specializing in structural engineering for timber, mixed wood-steel, metal, and concrete buildings. Founded over 30 years ago and headquartered at 19 Rue Danton, Le Kremlin Bicêtre (Île-de-France), the firm operates three interconnected service lines: (1) Expertise — diagnostics, structural reinforcement studies, and work monitoring for existing wood buildings, delivered as sapiteur services to judicial and insurance experts; (2) Ingénierie de structure bois — conception studies (ESQ, APS, APD, PRO-DCE, ACT, VISA, DET, AOR) within architectural design teams and execution studies (cutting plans, installation plans, hardware documentation, material lists, calculation notes) for carpentry contractors, using BIM methodology on complex projects; and (3) Maîtrise des systèmes constructifs — specialized studies across traditional carpentry, glulam (lamellé-collé), timber frame (ossature bois), CLT (bois lamellé-croisé), industrial carpentry, mixed wood/steel, composite floors, wood cladding facades, and reinforcement via resin and wood-steel bonding. The firm is led by Directeur Général Jean-Jacques GROSSIN and Directeur Jérémy DELEFOSSE.

The business model is professional-services / project-based: revenue is generated from three quoted streams — design studies with architectural teams, execution studies for carpentry companies, and technical-expert commissions for insurers and courts — with no disclosed pricing or subscription model. The firm is constituted as a SARL with €25,000 of registered capital, is privately held with no identified parent or external investors, and supports its work through direct enterprise and public-sector engagement rather than intermediated channels. Customers are spread across public-sector property owners (e.g., OPH Seine-Ouest Habitat, ICADE Promotion, Atlantique Habitations, Ville d'Ivry-sur-Seine, Communauté de Communes du Provinois, Ville de Maignelay-Montigny), enterprises (Saint-Gobain Recherche, ENGIE Cofely, Nexity Immobilier d'Entreprise, Grévin & Cie), and historic-monument restorations. The firm also participates in DTU standards drafting and sits on technical commissions of SCIBO and SNBL, reinforcing its influence at the regulatory layer of French wood construction.

Core offering

ERIBOIS & STRUCTURES is a French structural engineering bureau (Bureau d'Études Techniques) that designs and validates load-bearing structures for new-build and renovation projects involving wood, mixed wood-steel, metal, and concrete. The firm operates across three service poles: expertise and structural diagnostics of existing timber buildings, wood structure engineering (BIM-based conception and execution studies), and mastery of multiple construction systems (traditional carpentry, industrial framing, glued-laminated timber, CLT/lamibois, mixed wood-steel, and metal).

Product overview

ERIBOIS & STRUCTURES is a Bureau d'Etudes Techniques (technical engineering firm) specializing in wood construction structures. The company operates three interconnected service poles: Expertise (structural analysis and diagnostics for existing buildings and judicial/insurance expertise), Ingénierie de structure bois (wood structure engineering for design and execution studies using BIM methodology), and Maîtrise des systèmes constructifs (mastery of construction systems covering traditional carpentry, CLT, glued laminated timber, and mixed wood-steel structures). The firm works primarily in Île-de-France and throughout France on various building types including public facilities, housing, commercial, tertiary, and historic restoration projects.

Functional benefit

Products and services

• Expertise and Structural Diagnostics Structural analysis, appraisal, and diagnostic reports on existing timber buildings for owners, insurers, and legal experts. The service covers condition assessments, failure-cause investigations, and expert-witness reports used in insurance claims or litigation involving wooden structures.
• Wood Structure Engineering (BIM-based Conception) End-to-end structural engineering of timber buildings using BIM methodology, from preliminary/conception studies (ESQ, APS, APD) to execution studies (EXE/DOE) and structural calculations. Delivered to architects, construction companies, and property owners for new-build and renovation projects in wood, mixed wood-steel, metal, and concrete.
• Construction Systems Mastery Consultancy Technical advisory and engineering on the choice, detailing, and implementation of wood construction systems, including traditional carpentry (charpente traditionnelle), industrial framing (ossature bois), glued-laminated timber (lamellé-collé), CLT/lamibois panels, mixed wood-steel (mixte bois-acier), and metal (charpente métallique). Targeted at carpentry firms, contractors, and project owners evaluating system alternatives.

Broad incumbents

• Artelia Group: Large French engineering consultancy covering buildings, infrastructure, and industry with significant structural engineering practice. Similar professional services business model serving architects, owners, and contractors in France; broader portfolio and not wood-specialised.
• Arcadis: Global design and engineering consultancy with substantial French operations covering buildings and sustainability. Comparable as a France-served international engineering consultancy addressing building-sector clients; far broader portfolio and not specialised in wood.
• AtkinsRéalis: International engineering consultancy (formerly SNC-Lavalin) with French presence delivering building, nuclear, transportation, and infrastructure engineering. Comparable as a France-served international engineering consultancy addressing complex building structures, though broader and far larger.
• Bureau Veritas: French-founded global TIC and engineering consultancy with building and construction compliance and engineering services. Comparable as a France-headquartered engineering services firm working on construction and building projects; broader than wood-specialised Eribois.
• Setec Group: Leading French multidisciplinary engineering consultancy with strong structural engineering, BIM, and building-sector practices. Comparable along engineering service model, French market presence, and structural/civil engineering exposure; not specialised in wood like Eribois.
• WSP: Global engineering consultancy with significant French operations across buildings, environment, and infrastructure. Comparable as a France-serving engineering services firm in the structural and building-engineering space, though materially larger and broader in scope.
• Tractebel (Engie): International engineering consultancy subsidiary of Engie with strong French operations in building and infrastructure engineering. Comparable as a France-based engineering consultancy addressing complex building and structural projects; significantly larger and broader than Eribois.
• SOCOTEC: French leader in testing, inspection, certification, and construction-related consulting including structural diagnostics. Particularly comparable on the expertise/diagnostic pole of Eribois's activity (especially for insurance and judicial contexts), although SOCOTEC operates across many construction trades rather than specialising in wood.
• Egis Group: Major French multidisciplinary engineering consultancy with extensive building, infrastructure, and structural engineering practices. Comparable as a France-based engineering services firm addressing building structure needs, but materially larger and operating across transport, energy, and cities rather than specialising in wood.

Direct peers

• Arbonis: French wood construction specialist executing timber frame and large-scale timber projects. Comparable as a France-based, wood-focussed building-sector firm whose profile overlaps Eribois's wood specialist positioning, even though Arbonis operates downstream as a contractor/fabricator while Eribois operates upstream as a design consultancy.
