CONCEPTS BOIS STRUCTURE

What CONCEPTS BOIS STRUCTURE does

Concepts Bois Structure (CBS-CBT) is a Franco-Swiss group founded in 1991 by Jean-Luc Sandoz that engineers, designs, and constructs innovative large-span timber structures and supplies non-destructive wood-testing technologies. The group operates through two main legal entities: CBS SARL in Choisy-le-Roi, France, and CBT SA in Saint-Sulpice, Switzerland, with operating subsidiaries including LIFTEAM Romandie (Switzerland construction), CBS Travaux (France construction), and CBS Guyane (French Guiana); in October 2025 the prefabrication workshop ECOTIM SN was taken over by Atout Coffrage. CBS-CBT's portfolio splits into two complementary lines: (i) proprietary structural systems including the O'portune and O'Portune Klima slabs, D-Dalle timber-concrete slab, Ariane lattice trusses, noEcho acoustic panels, Solivium, Solium, AtlAs espAce porticos, Wenus panels, VéGA, Habitim housing, Noélit/Noétech agricultural buildings, and Jupit'air invisible fasteners; and (ii) non-destructive testing and grading equipment including Sylvatest (now in its fourth generation), Polux 5, Luxpole, Triomatic (homologated to EN14081-4), Logamatic log grader, and the SCIERIUS software for data analysis. Customers span public infrastructure (schools, sports halls, aquatic centres, the CNES Kourou technical centre, the Paris 2024 Olympics Follies Pavilion), commercial/hospitality (Hilton Paris La Villette conversion), industrial (ÖkoFEN headquarters), and agricultural use cases, with NDT equipment exported to roughly 30 countries.

The group monetises through three streams: structural engineering services (design, studies, expertise), hardware sales of NDT and grading equipment, and related technology services using Sylvatest/Polux expertise for diagnosis and reuse assessment. Pricing is fully quote-based via a 'devis' request workflow, and the go-to-market relies on enterprise field sales, architectural partnerships (Tectoniques, Ateliers Schweitzer, LA Architectures, So'Bois, Scoping), and regular presence at industry forums (Forum Bois Construction, Forum Holzbau Innsbruck, IEEE PES T&D, African Utility Week, SIBCA, Batimat). The technical edge rests on founder Jean-Luc Sandoz's EPFL IBOIS laboratory lineage, codified technical approvals (D-Dalle Avis technique through 2027, EN14081-4 homologation, FDES registrations in INIES), and a portfolio of registered brands covering both structural systems and NDT equipment.

Expansion highlights6 records

Broad incumbents

• Binderholz: Austrian mass-timber manufacturer producing CLT, glulam, and engineered wood products for construction. Comparable as a structural engineered-wood supplier but with much larger manufacturing footprint than CBS-CBT's boutique design-build model.
• Stora Enso Wood Products: Major European manufacturer of mass timber products (CLT, glulam, LVL) with growing integrated engineering services. Overlaps with CBS-CBT in mass-timber structural systems but operates at far larger scale and broader product scope, serving as an incumbent benchmark.
• Metsä Wood: Finnish manufacturer of engineered wood products (Kerto LVL, birch plywood) serving European construction. Overlaps with CBS-CBT's engineered wood product category and Ariane truss technology using birch plywood inserts, but at industrial scale rather than bespoke design.
• Ed. Züblin AG (MHM): Major German construction firm operating a dedicated mass-timber unit (MHM) for large-span timber buildings. Comparable to CBS-CBT in structural timber delivery for large commercial and public buildings but at much greater construction scale.

Direct peers

• Wiehag: Austrian timber engineering specialist known for large-span and record-breaking timber structures (sports halls, industrial buildings). Closely comparable to CBS-CBT's O'portune and Ariane truss systems targeting large free-span applications.
• Rotho Blaas: Italian manufacturer and supplier of timber construction hardware, connectors, and engineered solutions. Comparable to CBS-CBT's Jupit'air fastening system and engineering services focus on innovative timber connections for European timber projects.
• MiCROTEC: Manufacturer of industrial wood scanning, grading, and optimization equipment (CT Log, Goldeneye, Microtec) used by sawmills worldwide. Directly comparable to CBS-CBT's Sylvatest, Triomatic, and Logamatic ultrasound-based wood assessment and grading product lines.
• Rubner Gruppe: South Tyrolean/Italian timber engineering and construction group operating across glulam fabrication, structural design, and turnkey timber building delivery. Directly comparable to CBS-CBT as a vertically integrated timber design-builder serving European commercial and public infrastructure markets.
• Holzbau Amann: German timber engineering and construction firm focused on innovative solid timber and engineered wood systems. Comparable to CBS-CBT in structural innovation, DACH-region presence, and design-build delivery for commercial and public buildings.
• Blumer Lehmann: Swiss timber engineering, fabrication, and construction group with a long heritage in large-span and complex timber structures. Highly comparable to CBS-CBT in geography (Switzerland/European), structural-timber product portfolio, and design-build delivery model for commercial, public, and industrial buildings.
