The Process

The complex process of constructing a new tunnel begins with a careful comprehensive site evaluation that considers:

  • Environmental factors such as soil condition
  • Infrastructure factors like surrounding structures and utilities

Planning & Design

The planning and design phase is scrupulous and often involves many different engineering disciplines such as:

  • Civil, mechanical, and geotechnical

Site excavation methods include:

  • Mico TBM (Tunnel Bore Machine), drilling and blasting, or cut and cover

Ground support installation follows excavation and can include:

  • Shotcrete (pneumatically applied concrete), steel ribs (arch sets or ring sets), rock bolting, mine straps, mesh, or reinforced Shotcrete

Finishing steps in the process include:

  • Drainage and waterproofing, final lining and floor slab installation, MEP Installation (mechanical, electrical, and plumbing), and thorough testing & commissioning
