What THOMASSEN does

Thomassen & Fils srl is a Belgian family-owned general construction and public works contractor headquartered in Visé (Liège region, Wallonia), operating since the formal establishment of the SPRL on April 13, 1977, with predecessor activities dating to 1952. The firm delivers four integrated service lines: (1) Voiries & abords — road construction, rehabilitation, asphalt laying, drainage, and cable trenching; (2) Bâtiments publics & privés — demolition, construction, transformation, and renovation of public and private buildings; (3) Génie civil — civil engineering works including sewer collectors, earthworks, drilling, and demolition; and (4) Constructions métalliques — fabrication of guardrails, stainless-steel stairs, industrial halls, cladding, and structural steel framing. Underlying technology is standard heavy equipment (earthmoving, demolition, road construction) and metal fabrication capabilities — no proprietary technology platforms are identified.

The company's go-to-market is sales-led and project-based, combining competitive bidding on Belgian public procurement contracts (municipalities and government bodies) with direct engagement of private commercial, industrial, and residential clients. Revenue is generated through one-time, project-specific contracts priced via quotation, with billing cadence spanning multi-year engagements. The firm holds VCA* safety certification (since 2001, renewed June 2018) and Belgian entrepreneur agrégations in Category C&D Class 6 (Roads & Buildings) and Category F Class 5 (Metal Constructions), which are prerequisites for participation in public sector tenders. Customers are concentrated in Wallonia, with documented projects in Seraing, Visé, Glons, Huy, Liège, Louvain, Nivelles, Wanze, and Lixhe. The workforce stands at 60-70 employees, and ownership is held entirely within the Thomassen family across three generations.

Direct peers

• Franki (Willemen Group): Belgian contractor specializing in foundations, civil engineering, and building construction, now part of Willemen Group. Overlapping capabilities in heavy civil and nonresidential building construction make it a comparable, though better-capitalized, peer.
• Colas Belgium: Belgian arm of Colas Group focused on road construction, asphalt, and public works infrastructure. Comparable to Thomassen's Voiries & abords service line and public-sector client base, though operating at substantially larger scale.
• Wanty: Belgian general construction and public works contractor headquartered in Wallonia, with comparable service mix across roads, civil engineering, and buildings. Similar mid-sized regional profile makes it a close operational and competitive analogue to Thomassen et Fils.
• Galère: Belgian construction company operating primarily in the Liège region and broader Wallonia, active in civil engineering, public works, and building construction. Geographic overlap and similar public-sector client base position Galère as one of the most direct regional peers.
• Thomas & Piron: Belgian general construction firm delivering public and private buildings, civil engineering, and infrastructure projects. Comparable multi-trade service model and Belgian operating geography make it a relevant direct peer despite somewhat larger scale.
• CIT Blaton: Belgian family-owned construction company with roots in civil engineering and building construction, serving both public and private clients. Family ownership, multi-sector capabilities, and Belgian footprint align closely with Thomassen et Fils's profile.

Broad incumbents

• CFE (Compagnie d'Entreprises CFE): Listed Belgian construction group with activities in construction, real estate, and concessions across Belgium and internationally. Overlaps with Thomassen across buildings and civil engineering but operates at significantly greater scale and broader portfolio.
• BESIX Group: Largest Belgian construction group operating internationally across buildings, infrastructure, and marine works. Overlaps with Thomassen in nonresidential building and civil engineering but with materially greater scale, geographic reach, and bonding capacity.
