Integrale Ingénierie

What Integrale Ingénierie does

Integrale Ingénierie (SAS INTEGRALE Ingénierie, registered in La Réunion, France) is a private multidisciplinary building engineering design office (bureau d'études techniques) founded in 2004 that delivers commercial, industrial, and tertiary building engineering services across the Indian Ocean. The firm operates through nine technical poles — Structure, Fluides, VRD, Sécurité Incendie, Industrie, QEB (environmental quality), R&D, BIM, and MDE (energy management) — covering the full project lifecycle from master planning and feasibility studies through detailed design, BIM coordination, construction supervision, and energy compliance. Its service portfolio addresses tropical-climate-specific challenges (natural ventilation, solar protection, cyclone resistance, Décret Tertiaire compliance, ICPE permitting) for owners, developers, architects, and industrial operators.

The group is structured around a La Réunion headquarters, a Saint-Paul agency, and three wholly-owned subsidiaries/branches: CANOPEE Engineering Ltd in Mauritius (since 2015), NOMADE Ingénierie in Madagascar (since 2016), and INTEGRALE Mayotte (since 2018), employing approximately 70 collaborators. Core technology is BIM-centric (Revit, AutoCAD, point cloud processing for renovation), supplemented by numerical fire safety simulation (FDS/CFAST) and an R&D division pursuing DC microgrid energy management and IoT-based predictive maintenance digital twins via CIFRE theses with academic partners.

The business model is traditional B2B professional services: project-based engineering consulting billed via quotes, with revenue generated across structural, mechanical/electrical/plumbing, fire safety, road networks, BIM coordination, environmental quality, and industrial process integration services. Go-to-market is direct enterprise field sales through local offices, supplemented by a multilingual website, technical blog content, and academic/industrial partnerships. The company self-reports revenue in excess of €50 million and describes itself as a leader in commercial and industrial building engineering for the Indian Ocean and African markets. Ownership remains with founding leadership (Cyrille BOUARD as CEO, Laurent LEMAITRE as Managing Director); no external institutional investors are disclosed.
