Transportation

Project

Metro-scale station caverns and twin running tunnels on a large-scale urban rail programme.

Deep cavern station boxes, cross passages and running tunnels designed for a major metropolitan network.

Working in sandstone with variable cover, the team designed primary support that balanced excavation sequence, ground movement and construction programme. Our engineers provided on-site construction phase engineering, instrumentation design and interpretation, and specialist shaft and excavation support design.

Scope of work

  • Tunnels & Underground Engineering
  • Geotechnical Engineering
  • Construction Management
Hoffman Tunnels provided tunnel and underground design, engineering and construction-phase support.
