Etnap

What Etnap does

ETNAP b.e.t is a French technical engineering firm (bureau d'études techniques tous corps d'état) founded in 1975 and headquartered in Sainte-Catherine-lès-Arras, in the Hauts-de-France region. The firm delivers multidisciplinary engineering services across structural, thermal, electrical, infrastructure (VRD), and asbestos-related studies for the construction sector, serving a client base dominated by public-sector entities, social-housing operators, healthcare institutions, heritage/cultural organizations, and commercial developers. ETNAP operates with approximately 20 employees and holds OPQIBI 1332 qualification (2019) and RGE certification, which are required to bid on regulated French engineering and energy-renovation mandates.

ETNAP generates revenue through project-based engineering fees, typically structured as a percentage of underlying construction value, with disclosed individual project mandates ranging from €800K to €13M in construction cost. The firm's go-to-market is anchored in public-sector tenders and long-standing institutional relationships in the Hauts-de-France region, supplemented by recognition through industry awards (Grand Prix SIMI 2018, Rubans du Patrimoine 2020). The firm operates OPTERE as a dedicated thermal engineering subsidiary, providing energy-performance and HVAC study services. The business model is essentially services-led and project-driven, with no disclosed technology platform, recurring software revenue, or AI-driven tooling layer — revenue scales with engineering hours billed and the volume of public-sector mandates secured.

Direct peers

• Verdi Ingénierie: Independent French BET specializing in sustainable and energy-efficient building design, including RE 2020, BBC/BEPOS labels, and thermal engineering. Closely mirrors ETNAP's positioning around sustainable construction and thermal subsidiary (OPTERE equivalent).
• Ginger (Socotec): French engineering bureau (BET) acquired by Socotec, offering structural, thermal, and environmental engineering across all building trades. Directly comparable to ETNAP as a full-service BET serving public and private sector clients with maître d'œuvre and project management capabilities.
• Setec Bâtiment: French engineering consultancy with a dedicated bâtiment division covering structural, technical (CVC/fluids), and project management. Comparable TCE engineering model to ETNAP, serving similar healthcare, public, and private sector clients.

Broad incumbents

• Egis: Large French engineering group with substantial building, infrastructure, and environmental engineering capabilities. Competes for major public tenders ETNAP targets but at much larger scale and geographic breadth.
• Bureau Veritas Construction: International testing, inspection, and certification group with a construction services line offering technical control, building commissioning, and engineering consulting. Comparable in regulatory thermal studies, energy audits, and sustainability verification work.
• INGEROP: French engineering firm providing building, infrastructure, and environmental engineering. Directly competes for large public tenders and offers comparable maître d'œuvre services for healthcare, social housing, and public projects.
• Artelia: Major French engineering group providing bâtiment, infrastructure, and industrial engineering. Overlaps with ETNAP on building maître d'œuvre work but operates at significantly larger scale across multiple geographies and disciplines.

Emerging players

• SCE (setec, in some regions): French engineering firm focused on building environmental performance, energy, and sustainable development. Overlaps with ETNAP/OPTERE on thermal engineering, RE 2020 studies, and energy efficiency consulting for new and renovated buildings.
