What compagnie generale de construction does

Compagnie Générale de Construction (CGC) is an independent French general construction contractor (entreprise générale) founded in 2005 and headquartered in Lezennes in the Lille metropolitan area (Hauts-de-France), with a registered office at 19 avenue d'Italie, 75013 Paris (RCS Paris B 485 016 497). The company delivers projects across three core market segments: residential housing (social, student, private accession, mixed-use), tertiary and commercial real estate (offices, business parks), and public equipment (schools, colleges, cultural venues, community facilities). Its client base spans property developers, social housing providers, private investors, corporate occupiers, and public authorities across northern France, with named clients including ICADE Promotion, VINCI Immobilier, Partenord Habitat, Lille Métropole Habitat, 3F Notre Logis, SIGH, Aventim/SNC Parc, Becity, Anios, EDHEC, CROUS de Lille, the Département du Nord, the Région Hauts-de-France, and the Ville de Villeneuve d'Ascq.

CGC offers five service lines: Entreprise Générale (full general contracting across all trades/TCE), Gros Œuvre (specialist structural reinforced concrete), Réhabilitation-Rénovation (occupied and unoccupied renovation), Conception-Réalisation and Marché Global de Performance (design-build and performance-based contracts), and Ingénierie Études de Prix (cost engineering). The underlying technology stack centres on conventional reinforced and prestressed concrete construction, anchored by dual Qualibat certifications (2112 Maçonnerie/Béton Armé and 2212 Béton Armé/Béton Précontraint, both at Technicité confirmée), and is extended by expertise across evolving French energy and environmental standards (RT 2012, RE 2020, BBC Effinergie, PassivHaus) and building certifications (NF Habitat, NF Habitat HQE, HQE, BREEAM, BEE+, Biodivercity, REV 3). The company integrates biosourced materials, low-carbon concrete, on-site waste sorting and recycling, and CO2 compensation as part of a stated carbon neutrality objective.

CGC generates revenue through fixed-price construction contracts won via French public procurement tenders and direct commercial negotiation with private developers and investors, acting as either main general contractor or specialist structural subcontractor. Sales are pursued through an enterprise field-sales motion targeting mid- to large-scale projects in the Hauts-de-France region, supplemented by active recruitment and school-enterprise engagement to build pipeline. Sébastien Masclet serves as founding managing director (Dirigeant Fondateur Associé / Directeur Général); in 2025 Jimmy Baert was appointed Regional Director to accelerate growth and strengthen territorial presence, with Philippe Beauchamps as Secrétaire Général and Christine Lecollier as Directrice Administrative et Financière. The company employs more than 130 collaborators and has completed over 100 construction projects since founding.

Revenue model

1. General construction contracting (Entreprise Générale): CGC acts as a general contractor (entreprise générale) on construction projects, delivering complete works across all trades (TCE – tous corps d'état). Revenue is generated through fixed-price contracts on a per-project basis, encompassing design-build (conception-réalisation), performance contracts (marché global de performance), and traditional lump-sum contracts for both public and private clients. The company also operates as a specialist trade contractor (lotisseur/gros œuvre) for structural works only.
2. Gros œuvre (Structural concrete) subcontracting: CGC provides reinforced concrete structural works as a specialist trade contractor (lot gros œuvre) on projects led by other general contractors or developers. This stream covers structural framing, foundations, and concrete work on residential, tertiary, and public buildings.
3. Rehabilitation and renovation: CGC undertakes building rehabilitation and heavy renovation projects in both occupied and unoccupied settings, delivering structural and all-trades solutions for existing buildings requiring modernization or change of use.
