ALTEABOIS

What ALTEABOIS does

Altéabois is a French engineering consultancy (Bureau d'Études Techniques) established in 2011 by Gilles Amblard, an engineer from Arts et Métiers with over 30 years of construction experience. The firm specializes exclusively in structural engineering for wood construction and mixed wood/concrete/metal structures, with technical proficiency in engineered timber systems including glued laminated timber (lamellé-collé), cross-laminated timber (CLT), and timber frame (ossature bois). Core deliverables include Maîtrise d'Oeuvre (MOE) project management, BET EXE/PAC execution studies, structural and sanitary diagnostics, Sapiteur BET expert witness services, thermal and environmental engineering (including lifecycle assessment/ACV), and BET VRD civil engineering. The firm operates from Montferrier-sur-Lez near Montpellier, France, serving clients nationwide through direct engagement rather than intermediaries, with notable reference projects ranging from €40K residential extensions to €29.6M school campuses (Lycée Simone Veil, 15,000m²).

The firm targets three primary client segments: public-sector clients (Conseils Départementaux, Régions, Communes, MUCEM, SNCF Gares et Connexiones commissioning public buildings, schools, cultural venues, and transport infrastructure); private real estate developers (OPH Perpignan, Hérault Habitat, Bouygues Immobilier for housing projects); and private individuals seeking bioclimatic timber homes. Diagnostic services for existing timber structures are a secondary vertical leveraging 3D scanning, drone inspection, and connected crack gauges. Revenue is generated through professional services fees structured per project based on scope, surface area, and complexity — no subscription, transaction, or product revenue model is employed.

Altéabois differentiates on environmental credentials, holding BDM Or, BDO Or, BBC, and RT2012 certifications across projects, and on biosourced material expertise (straw-bale insulation, local species such as Douglas pine). The firm has won multiple national-level awards including two 2nd Prix National Construction Bois (2016, 2017). Membership in IBC (Ingénierie Bois Construction) provides industry positioning. The business is structured as a SARL (private limited company), founder-owned, with no external investment or parent company disclosed, operating from a deliberately lean 10-person team of specialist engineers, BIM technicians, and drafting staff supported by an apprenticeship pipeline.

Direct peers

• StructureCraft: Canadian timber engineering and construction firm specializing in mass timber, CLT, and glulam structures for public, cultural, and commercial buildings. Directly comparable to Altéabois as a timber structural engineering specialist, with comparable project scale, sustainability focus, and award-winning mass-timber portfolio.
• Bollinger + Grohmann: German-founded engineering firm with deep timber and hybrid-structure expertise operating across Europe. Comparable to Altéabois as a structural engineering consultancy specializing in timber and mixed-material building systems for cultural, public, and residential clients.
• Pirmin Jung Ingenieure: Swiss engineering consultancy specializing in timber and hybrid timber structures across Europe. Closest functional peer to Altéabois as a timber-only structural engineering BET serving public, cultural, and residential clients with award-winning, sustainability-focused wood projects.

Broad incumbents

• Egis: Major French engineering group with broad structural, building, and infrastructure practices serving public and private clients across France. Comparable to Altéabois as a French engineering services buyer of structural engineering capacity, though Egis operates at vastly greater scale across multiple specialties rather than wood-specific niche.
• Setec: French engineering group with structural and building design practices serving infrastructure, transport, and real-estate clients. Comparable to Altéabois as a French structural-engineering competitor in the same public/private client pool, though Setec spans far broader end-markets than wood-only BET work.
• Artelia: French engineering consultancy with construction, structural, and environmental practices serving public and private developers. Comparable to Altéabois as a French engineering services firm competing for public-sector and developer mandates, though Artelia is a broad multi-specialty incumbent rather than a wood-only BET.
