What bureau d'etudes de structure fettet does

Bureau d'études de structure bois Fettet (BET Fettet) is a privately held, family-owned French engineering consultancy founded in 1986 in Wittelsheim, Alsace, and organized as a S.A.R.L. The firm provides structural engineering services for timber construction, covering feasibility studies, structural calculations, execution plans, workshop drawings, and technical support for solid wood and glued laminated timber (lamellé collé) structures as well as timber frame (ossature bois) buildings. All design work conforms to Eurocode 5 standards, and the firm has developed a niche specialization in evaluating load capacity, reinforcement, and wind/snow loads for photovoltaic panels integrated onto wood rooftops.

The technical stack centers on two BOCAD 3D CAD stations for workshop drawings and fabrication documentation, supplemented by two dedicated Eurocode 5 calculation software packages. Deliverables are exported in DXF, DWG, and BMF formats compatible with CNC machinery used by carpentry workshops. The product portfolio is organized around seven service lines: structural studies for timber trusses, timber-frame buildings, PV-integrated roofs, structural diagnostics of existing wood structures, workshop plans, execution studies, and project management (maîtrise d'œuvres).

Commercially, BET Fettet operates a sales-led, project-based professional services model with no publicly disclosed pricing or fixed fees. The primary customer segment is French public-sector communes and government entities (schools, sports halls, aquatic centers, health centers, waste facilities), with secondary work for private industrial/agricultural developers, architects, and carpenters. Projects span Alsace and extend into Nord, Pas-de-Calais, Vosges, Moselle, and Reims. The firm is managed by Bernadette Fettet (gérante), with founder Patrick Fettet leading engineering and his son Michael Fettet (BTS-qualified, joined 2007) handling technical studies, with no external investors and no disclosed funding.

Direct peers

• Simonin SAS: French engineered-timber specialist designing and manufacturing glulam and timber-frame structures with in-house structural engineering — operates in the same niche as BET Fettet (engineered timber, Eurocode 5) but at significantly larger scale, making it both a direct competitor and a structural integration reference point.
• Mathis SAS: Alsatian timber construction company (also headquartered in eastern France) with engineered-wood design, prefabrication, and structural engineering across lamellé collé and ossature bois — directly comparable in geography, product scope, and customer profile (communes, public buildings, timber frames).
• Piveteau Bois: French engineered-timber manufacturer and engineering services provider focused on glulam structures, timber frames, and large-span public/commercial buildings — same engineering-to-timber value chain BET Fettet serves, but with a manufacturing footprint that creates both partnership and competitive overlap.
• Ossabois: French timber construction firm specializing in industrial and residential timber-frame projects with integrated design and engineering — serves the same commune/developer customer base on public and private timber buildings, often via parallel design-build and study-only paths.

Broad incumbents

• Arbonis: Timber construction subsidiary of Bouygues Construction offering design, engineering, prefabrication, and assembly for large multi-story timber buildings — operates at broader scale and wider project scope than BET Fettet, often as a vertically integrated timber specialist on tenders where BET Fettet would be a third-party engineer.
• Egis: Large French engineering group delivering full-scope structural, civil, and building engineering across infrastructure and buildings — overlaps with BET Fettet where major public tenders require multi-discipline engineering and wood is one structural option among many.
• Artelia: Major French multi-disciplinary engineering firm (BTP/structures/maritime/energy) with building structure capabilities — competes for the larger commune-led, public-private construction projects BET Fettet also targets, but as a generalist rather than a wood specialist.
• Setec: Independent French engineering group providing structural, civil, and project management services across transportation, buildings, and energy — participates in the same public-sector construction tenders as BET Fettet, particularly on buildings where timber may be specified but other materials are also bid.

Emerging players

• Egoin: European engineered-timber group (Spanish/French footprint) with mass-timber and glulam engineering and construction capability — overlap on Eurocode 5-style timber engineering design work for public/commercial buildings, particularly in CLT/CLT-adjacent projects.
• Techniwood: French timber engineering firm developing industrialized timber building systems and structural solutions for low- and mid-rise buildings — partial overlap with BET Fettet's lamellé collé and ossature bois expertise, focused on productized CLT-style solutions.
