Bridge, road & geotechnical
Engineering support for bridges, roads and ground works, from preliminary design to execution drawings and VISA checks.
From ground to structure
One team covers geotechnics, foundations, retaining structures, bridges and roads.
French project phases
We join at APS, APD, PRO, EXE or VISA and produce what each phase expects.
Seismic know-how
Seismic evaluation and design to EN 1998, including post-elastic diagnosis of existing bridges.

Where we can join your project
| Phase (French practice) | Our contribution |
|---|---|
| APS / APD – preliminary & detailed design | Calculation models, sizing, alignment studies, quantity estimates |
| PRO / DCE – technical design | Calculation notes, design drawings, bills of quantities |
| EXE – execution | Execution drawings, reinforcement and steel shop drawings, BIM models |
| VISA – checks and updates | Design review, comment responses, as-built updates |
Standards
Eurocodes EN 1990–1999, including geotechnics (EN 1997) and seismic design (EN 1998); French rules (PS 92, BAEL, DTU, fascicules); AASHTO; national annexes on request.
Relevant experience
In France and Morocco: Dhuys bridge, Laval footbridge, Brest cable tram, seismic evaluation of the Moulay El Hassan bridge, retaining walls and barrette piles for Paris Metro line 16. In Vietnam: road network 1A at Hoa Lac, internal roads and planning for border-gate and urban areas. See the references
