What Lemaire Engineers does
Lemaire Ingénieurs (legal entity: Bureau d'études LEMAIRE) is a Belgian multidisciplinary engineering consultancy headquartered in Grace-Hollogne near Liège, with a second office in Brussels (Auderghem). Founded in 2000 by civil engineer Frédéric Lemaire, the firm provides integrated engineering studies for building construction across four poles: Stability (structural engineering), Special Techniques (HVAC, electrical, plumbing), Infrastructure, and Energy. The company serves public institutions, private developers, industrial companies, and large enterprise clients — including Pfizer, Apple, Decathlon, the Université Catholique de Louvain, Cliniques Universitaires Saint-Luc, and SWDE — across verticals such as healthcare facilities, offices, retail, residential, industrial/logistics, public infrastructure, and hospitality in the Wallonia and Brussels regions.
The current corporate form was assembled through two prior integrations: the 2011 merger with Brussels-based ELLYPS (adding hospital and infrastructure specialization) and the 2016 integration of BEOS as a dedicated Energy department (adding environmental, biomass, cogeneration, and district heating expertise). In 2022 the three entities were rebranded under the unified Lemaire Ingénieurs identity, coinciding with the construction of a new BREEAM Excellent-certified headquarters near Liège Airport and relocation of the Brussels office. The firm employs approximately 95 engineers, consultants, and CAD drafters, organized under a seven-member management committee that covers each technical pole.
The business operates as a project-based professional services consultancy, generating revenue through negotiated engineering study fees tied to project scope and complexity. Distribution is via direct client engagement, partnerships with architectural firms as part of integrated project teams, and participation in public procurement tenders. The technology stack centers on Building Information Modeling (BIM) for spatial coordination and data management, dynamic thermal simulation, and Building Energy Performance (PEB) studies. Consolidated revenue for FY2021 was €11.8 million, with the firm remaining privately held under founder and Managing Director Frédéric Lemaire with no external investors.
