Tunnels

Many large Power, Sewer and Subway Tunnels have been estimated utilizing our Heavy Civil database.

Tunnels usually require a significant investment in specialized tunneling equipment customized for the specific size and geotechnical conditions of the project. The estimates are broken down in such a way that the initial mobilization costs of the launch facilities, the purchase of specialized equipment like Tunnel Boring Machines or Drill Jumbos and the purchase of Tunnel Services are kept separate from the tunnel drives themselves.

Included in our Master Work Breakdown Structures are all the major elements that make up a tunnel project including;

  • Site Preparation
  • Utility Relocations
  • Instrumentation & Monitoring
  • Launch & Extraction Shafts
  • Headwalls
  • Jet Grouting
  • Emergency Exit Shafts
  • Specialized Tunnel Equipment
  • Mobilization of Equipment
  • Tunnel Services
  • TBM Drives
  • Drill & Blast Drives
  • Temporary Support
  • Handling of Tunnel Muck
  • Precast Concrete Liners
  • Cast-in-Place Concrete Liners
  • Cross Passages
  • Mechanical & Electrical Systems
