BSC

What BSC does

BSC Ingénieurs-conseils S.A., doing business as Building Solutions & Consulting, is a Luxembourg-registered engineering consulting firm founded in July 2016 as a wholly-owned subsidiary of LSC Engineering Group. The company specializes in 'techniques spéciales' — the design and supervision of building technical systems — across four disciplines: HVAC (heating, solar, ventilation, air conditioning, refrigeration, urban energy networks), electrical installations (medium/low voltage, security, safety, weak currents, lighting and photovoltaic simulation), sanitary systems (sprinklers, fire networks, fluid supply, wastewater and rainwater networks, harvesting), and lifting installations (passenger, vehicle, and freight elevators). A second service line, Energy and Environment, is delivered in collaboration with Simon-Christiansen & Associés' QSE² department and covers Passive House certification, BREEAM, Blowerdoor testing, thermography, thermal bridge analysis, and Commodo/Incommodo permitting.

The firm operates as a project-based B2B/B2G professional services business. Revenue is generated through fee-for-service engineering studies ranging from full-scope project studies from planning to construction supervision to customized 'à la carte' technical studies. Pricing is quote-based and not publicly disclosed. Customer segments include professional clients (developers, architects, construction firms), public organisms and communes, and individual private clients; the project portfolio spans office buildings (Post Luxembourg 25,000m² at Cloche d'Or), administrative buildings (Losch-Houbesch), schools (Bildungshaus Reuler with 100% geothermal), hospitality (Novotel Kirchberg, Restaurant Lakeside), sports infrastructure (FC Rodange 91 stadium), and international public-sector projects (Senegal CRMN Digital Skills Center). Distribution is direct enterprise field sales through professional referrals and the LSC Group brand network; marketing is conducted via the corporate website, LinkedIn, Facebook, and industry seminars.

The company is led by Managing Director (Administrateur délégué) Julien BOURGUIGNON alongside Geoffrey MAZZUCOTELLI, and is one of nine Luxembourg and six international entities comprising LSC Engineering Group. Headquartered at 4 rue Albert Simon, Contern (relocated January 2022), BSC employs approximately 20 specialized staff as part of a 300+-employee group with 44 years of operating history. The firm holds OAI (Ordre des Architectes et des Ingénieurs-conseils) professional membership and ESR (Entreprise Socialement Responsable) certification awarded July 2019, and in July 2025 acquired a minority stake in enerventis Lux SA as part of a cross-border partnership with enerventis Deutschland to expand building-technology capabilities in the German and Luxembourgish markets.

Broad incumbents

• Sweco: European engineering and architecture consultancy with significant building-services/energy practice. Comparable to BSC in providing MEP-style technical studies to public and private clients across Europe.
• Arup: Global engineering consultancy renowned for MEP and sustainable building design. Comparable in service offering (technical studies, energy performance, sustainability certification support), but operating at much larger scale and brand recognition.
• WSP Global: Global professional services firm with a large buildings/MEP practice. Highly comparable in offering (engineering consulting for HVAC, electrical, sustainability) but operates at vastly greater scale across many geographies rather than specializing in a single small market.
• Arcadis: Global design and engineering consultancy with a strong buildings and sustainability practice. Comparable to BSC in delivering MEP-adjacent engineering services for real estate and public-sector clients, but with a much broader portfolio and international scale.
• Ramboll: Engineering consultancy with leading building-services and energy-efficiency expertise. Comparable to BSC in technical depth on sustainable building design, though Ramboll is a multi-thousand-employee, multi-disciplinary global firm.
• Tractebel (Engie): Engineering consultancy focused on energy, water and built environment, with strong MEP and sustainability DNA. Comparable in technical services delivered to BSC's customer set.

Direct peers

• Hoare Lea: UK-based building-services engineering consultancy focused on MEP design and sustainability. Directly comparable to BSC in scope of services, customer type and consultancy-led project delivery.
• Meinhardt Group: International engineering consultancy with strong MEP, sustainability and smart-building capabilities. Closely comparable to BSC's special-techniques service lines, with a presence in Asia/Australia and a few European markets.
• Buro Happold: Independent engineering consultancy with a dedicated building-services / MEP practice and strong sustainability credentials. The closest direct analogue to BSC in size and specialization, though with a much broader geographic footprint.

Regional players

• BG Ingenieurs Conseils: Luxembourg-headquartered multidisciplinary engineering consultancy (building, infrastructure, environment). Most regionally comparable peer to BSC, competing for similar public- and private-sector mandates in the Grand Duchy.
