What Engeco does

Engeco S.A.M. is a Monaco-based general construction and civil engineering contractor (Entreprise Générale de Construction) operating exclusively in the Principality of Monaco. Founded in 1984 by Stefano Casiraghi and remaining under Casiraghi family control, the company delivers turnkey (clés en main) building and infrastructure projects through two main business units: Public Projects (serving the Direction des Travaux Publics de Monaco and other state entities) and Private Projects (luxury residential, commercial, hotel and office construction for high-end developers and institutions). Visible marquee projects include the Yacht Club de Monaco, EVOS – Entrée de Ville Ouest Supérieure, L'Exotique, Monte Carlo View, Gare Maritime, Monaco Freeport 2024 and the reconstruction of Villa Belgica, with several projects certified under HQE, BREEAM and BD2M environmental frameworks.

Technically, Engeco's differentiation rests on complex-method construction capabilities rather than proprietary software: ultra-high performance fibre-reinforced concrete (UHPFRC) architecture (12-metre monolithic prefabricated columns at L'Exotique's Propylée structure), marine foundation and underwater concrete-plug work (Yacht Club de Monaco, executed entirely underwater), and micro-blasting excavation in Jurassic limestone for deep subterranean projects. These capabilities are complemented by a four-decade-curated network of specialist subcontractors covering demolition, earthworks, underpinning, acrobatic works, technical lots, and façades.

Engeco generates revenue exclusively through fixed-price general contracting contracts awarded directly via client relationships, public tender participation, and referrals from architects and design firms (Foster & Partners, Rudy Ricciotti, Wilmotte S.A.) — no projects are sold through distributors, digital channels, or resellers. The customer base is highly concentrated between a small set of public authorities and a handful of Monegasque real estate families and institutional clients (e.g., UBS Monaco SA, Fine Properties Monte-Carlo, Michel Pastor Group, S.E.G.E.M.). Pricing is quote-based and negotiated per project; no standard pricing model is publicly disclosed. The company holds HQE, BREEAM, BD2M certifications, is a signatory to Monaco's National Pact for Energy Transition and a member of Charte Bois, and was designated an OPPBTP Partner 2024 for safety prevention.
