CMC Promotion Construction

What CMC Promotion Construction does

CMC Promotion Construction (Clé en Main Construction) is a privately held French general contractor (contractant général) founded in 1990 in Lyon, operating under a Société Anonyme structure with €300,000 share capital. The company delivers turnkey commercial and industrial buildings for businesses in the Lyon agglomeration and surrounding Rhône-Alpes region, serving as the single point of accountability from initial concept through key handover. Christophe Guerci leads as President, with family members and associates in operational and equity roles.

The firm runs four integrated service lines: Bâtiment Clé en Main sur Terrain Maîtrisé (building-plus-land packages), Parc d'Activités (modular business park units from 150 to 1,000 m²), Bureaux (custom office construction), and Rénovation (industrial site modernization for environmental and thermal compliance). CMC has completed over 250 buildings, with project scale ranging from 90 m² renovations (SANTOS) to 30,830 m² activity parks (MARRONNIERS). Customer logos span CONTINENTAL, PATHEL/Hydroscand, ETANDEX, UNIBIO, Explor'Air, ADVANTELEC, and others across batteries, medical labs, food equipment, and industrial fittings. Delivery relies on three wholly-owned subsidiaries — Aluclip (aluminum), EGS Elec (electrical), and EGS Clim (HVAC) — providing vertical integration across key building trades.

Revenue is generated on a project-by-project basis under fixed-price contracts, with pricing determined per quote by surface area, complexity, materials, and site conditions. GTM is exclusively direct enterprise sales through website inquiries, referrals, and proactive business development in Lyon, with no distributors or resellers. The company operates from a single headquarters at 354 rue André Philip, 69007 Lyon, and maintains a LinkedIn presence alongside its website as the primary top-of-funnel marketing channel.
