What Interconstruct does

Interconstruct SA is a Belgian general construction company (entreprise g\u00e9n\u00e9rale de construction) founded in 1987, headquartered in Mouscron (Wallonia) and operating primarily in the Walloon region of Belgium. The firm holds the agr\u00e9ation en classe 7 (Class 7), the highest construction qualification tier in Belgium, which permits it to bid on the largest and most complex public and private projects. It employs approximately 100 workers and delivers projects that range from roughly \u20ac575,000 for smaller municipal works up to \u20ac13,000,000 for large multi-building residential schemes.

Its service scope spans industrial buildings, nursing homes and service residences, office and administrative centers, apartment complexes, wastewater treatment plants, and foundation/groundwork. A specialty line is sustainable construction, exemplified by the C.R.I.E. d'Harchies \u2013 delivered in 2019 as the first public building in Belgium using a timber-frame structure insulated with straw bales, built in partnership with specialized subcontractor Paille-Tech. On the residential side, the company has begun acting as a developer-seller of completed apartment units, as with R\u00e9sidence Clovis Poullet sold under VAT regime.

The business model is project-based general contracting: revenue is earned through construction contracts awarded via direct bidding on public procurement (march\u00e9s publics) and private tenders. Pricing is quote-based and competitively bid, and contracts typically run multi-year (e.g., 2011\u20132015 for Ath R\u00e9sidences Les Pr\u00e9s du Roy). The customer base is anchored by Belgian municipal and governmental clients \u2014 Ville de Mouscron, Service Public de Wallonie, CPAS Havr\u00e9, Ville de Tournai \u2014 alongside private real-estate developers. The company markets primarily through a project portfolio on its corporate website and earned media (Dezeen, L'Avenir, NordEclair, RTBF), with no evidence of software, AI, or platform components in its offering.
