  • Geotechnical and hydrological surveys
  • Tunnel excavation using both drill-and-blast and mechanised technologies (including TBMs)
  • Tunnel reinforcement, internal concrete encasement and waterproofing
  • Construction of entrances, emergency exits and service chambers
  • Installation of ventilation, lighting and drainage systems
  • Integration of tunnels into existing transport networks
  • Refurbishment and major repairs of existing tunnels
