What SGI does

SGI Groupe (legal entity SGI CONSULTING S.A., RCS B 55943) is a multidisciplinary engineering consultancy headquartered in Junglinster, Luxembourg. Founded in 1898, the firm operates across three core domains — Building, Transport, and Water/Environment — providing structural studies, civil engineering works (bridges, tunnels, viaducs), hydraulic engineering (dams, treatment stations, hydroelectric plants), infrastructure studies (roads, railways, networks), and building technical systems (HVAC, electrical, sanitary). It also delivers specialised services such as work direction (quality control, safety coordination), expertise and inspection, and project management (AMO).

Its technology stack is anchored on BIM, with a proprietary BIMCARE lifecycle methodology covering audit, project follow-up, team support, and experience feedback, augmented by an augmented-reality BIM capability developed in partnership with Genievision. The Fit4Sustainability consulting line, accredited by LuxInnovation, extends the offering into decarbonation, water, and circularity advisory.

SGI operates a sales-led, project-based B2B professional services model, generating revenue from engineering study fees, BIM management mandates, construction supervision, and expert assessments. It targets government and public-sector clients (municipalities, public administrations, ministries, public utilities) and large private developers and corporates across Luxembourg, France, Switzerland, and francophone Africa, with landmark references including the BGL BNP Paribas headquarters, the Luxembourg tramway, SEBES water treatment, and the Complexe Industrialo-Portuaire de Kribi in Cameroon.
