Energy & Mining

Project

A 4.5-mile deep neutrino research cavern complex in a former gold mine.

Support caverns, galleries and shaft works for the world’s largest particle physics experiment.

Extremely low vibration, radiation shielding and long-term stability governed every support decision across the underground complex.

Scope of work

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