Setec Diadès

What Setec Diadès does

Setec Diadès is a French engineering consultancy founded in 2008 as a subsidiary of the setec group, specializing in structural diagnostics, maintenance engineering, inspections, and repair design for civil engineering structures. The company serves public and private infrastructure owners across bridges, tunnels, dams, highways, and industrial facilities, with a client roster including APRR, SNCF Réseau, VINCI Autoroutes, SANEF, VNF, EDF, and DGITM. Operations are delivered through a Paris headquarters and five regional offices covering all major French regions (Vitrolles, Lyon, Bordeaux, Strasbourg, Nantes), with selected international projects in Morocco, Turkey, and Madagascar.

The company's core technical offering is organized around seven service lines: AMO/consulting/research/training, visual inspections, drone-based structural controls, recalculations and diagnostics, design engineering (Maîtrise d'oeuvre études), construction supervision (Maîtrise d'oeuvre travaux), and durability/service-level studies. Two proprietary technology assets underpin the offering: IDNT© (Inspection Détaillée Nouvelles Technologies), a patented stealth tunnel inspection system combining optical, infrared, profilometric, and environmental sensors in a single mobile unit; and Dia-Map©, an internally developed software platform for processing drone-acquired inspection data and georeferencing defects on 3D structural models. The company operates a multi-vendor drone fleet (DJI Matrice 210/350 RTK, Mavic 2 Pro, Mavic 3, Mini 4 Pro) equipped with optical, thermal, LiDAR, and RTK/PPK sensors.

Setec Diadès generates revenue through project-based professional services contracts, with no public pricing disclosed. The go-to-market is sales-led, relying on direct engagement with infrastructure owners, technical expertise positioning through industry publications, and participation in professional associations (AFGC, IMGC, PIARC). The company reported revenue of €8 million and 75 employees as of 2024, with MASE safety certification and QUALIOPI training organization approval expanding its addressable scope on critical infrastructure.
