New Tunnel Construction
Creating an entirely new underground passageway.
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
