AREST Bureau d'Etudes Structure

What AREST Bureau d'Etudes Structure does

AREST Bureau d'Etudes Structure (SAS AREST, founded 1998) is a French structural engineering consultancy headquartered in Le Bignon near Nantes, with additional offices in Cholet and Niort, and a federation of affiliated group companies (EVEN STRUCTURES in Angers, AUBERT STRUCTURES near Tours, ERIBOIS & STRUCTURES in the Paris region, and EVEN PACA near Marseille). The firm employs approximately 60 staff and delivers five core service lines: structural studies for concrete buildings (Études structures béton), timber and metal carpentry studies (Études charpente bois et métal), structural diagnostics of existing buildings, BIM-based collaborative modeling using Autodesk REVIT with IFC interoperability, and construction economics services including quantity surveying, DPGF preparation, and bid analysis. Projects range from €145K to €140M construction cost, with specialization in EUROCODES-compliant calculations, seismic modeling (EUROCODES 1, 3, 5, 8), and non-destructive testing using Ferroscan, 3D reinforcement scanning, and corrosimeters.

The firm serves public sector project owners (departments, municipalities, public institutions), social housing providers (bailleurs sociaux), healthcare operators, retail and commercial developers, industrial clients, and architectural firms. Revenue is generated through project-based professional service fees, billed per project phase (feasibility, APS, APD, PRO, DCE, EXE) or as lump-sum mission fees under both public procurement frameworks (LOI MOP) and private contracts. Customer acquisition is relationship-driven via direct engagement with architects, project owners (maîtres d'ouvrage), and general contractors across western France (Pays de la Loire, Deux-Sèvres, Bretagne, and adjacent regions).

AREST operates an in-house tool stack under license — Autodesk (REVIT, AutoCAD, Robot Structural Analysis, Building Design Suite Premium 2020), GRAITEC (Advance Design, Arche Ossature), CADWORK for timber, and ATTIC+ integrated with REVIT for BIM-based quantity takeoffs. The firm is privately held as an SAS with €120,000 share capital, founded by Hubert PRENEAU and currently led by Pascal PINEAU (Gérant since 2016). The company differentiates through specialized diagnostic equipment, BIM-enabled delivery since 2015, multi-material expertise (concrete, timber, metal), and a regional office network that provides local proximity to clients.

Broad incumbents

• Bureau Veritas Construction: Global TIC group with extensive French construction control and structural assessment operations. Provides regulatory technical control (Contrôle Technique) overlapping with AREST's diagnostic and compliance work, but at vastly larger national scale.
• SETEC Group: French multidisciplinary engineering group with strong building and structural engineering practices (setec tpi, setec bau). Competitor for significant building and infrastructure mandates in the same EUROCODES/BIM framework AREST operates within.
• EGIS: Major French engineering group covering buildings, transport, energy, and urban development. Competes for structural and BIM mandates on large public and P3 projects where AREST would be a sub-consultant rather than lead.
• SOCOTEC: Major French TIC (Testing, Inspection, Certification) incumbent with structural diagnostic and building control capabilities. Overlaps with AREST's diagnostic pole (Ferroscan, corrosimeter) and serves public/private clients at national scale.
• ARTELIA: Leading French engineering and project management group (Building, Industry, Water, Energy). Competes for larger-scale structural engineering mandates that AREST cannot service alone, particularly major public and healthcare infrastructure.

Direct peers

• BET Iosis (Sweco France): French structural and civil engineering consultancy acquired by Sweco, providing BET Structure and infrastructure studies. Comparable in multi-disciplinary approach (concrete, steel, BIM) and public/private client mix.
• ICR I: French structural engineering lead (Maîtrise d'Œuvre) on motorway service area and commercial projects. Joint delivery with AREST on motorway projects (Limours, Romagnieu, L'Isle d'Abeau). Similar service portfolio targeting commercial/retail developers.
• EVEN STRUCTURES: Sister group company of AREST based in Angers providing concrete, timber and metal structural engineering studies across western France. Operates under the same group umbrella with identical service lines and customer base.
• KHEPHREN Ingénierie: French structural engineering consultancy offering BET Structure services (concrete, steel, timber) for buildings and infrastructure across multiple regions. Direct comparable to AREST in service portfolio, customer segments (architects, public, private), and regional mid-market positioning.
• COBI Engineering: French engineering consultancy providing project management (Maître d'Œuvre d'Exécution) on commercial and retail projects where AREST supplies structural studies — demonstrated via joint projects (Leclerc Blain, Super U). Closely aligned business model in building engineering.
