We provide design services for highway and subway tunnels from the survey stage to the detailed design. We determine the tunnel alignment and cross-section by evaluating topographic and geological-geotechnical data together with existing and planned infrastructure.
Scope of services
- Alignment and tunnel cross-section design
- NATM-based excavation and support system design
- Portals and approach structures
- Junction arrangements before and after the tunnel
- Lighting, ventilation and electromechanical design
- Traffic signage and safety systems
