Heaviest objects pushed by hydraulic jacks to build highway tunnel in British Columbia, Canada

As subcontractors on the Evergreen Line Rapid Transit Project, Hall Constructors were responsible for the Inlet Storm and Sanitary Line Relocation. The underground tunnel of this project is located on the west side of Barnet Highway, Coquitlam, BC.

The challenges of the project included:

  • Tunnel under a major commuter route in a high density area
  • Work at night
  • Significant noise restrictions to provide maximum quietness

The options considered were:

  • Cut and cover
  • Jack the box

Watch this video how Hall Constructors met the challenge.
