Project Size
2.5 km Tunnel
Year Completed
2018

The art and reality of coordination.

Smith + Andersen provided electrical engineering services for the tunneling portion of the Confederation Line in Ottawa. This massive transportation project in Canada’s capital involved the work of numerous firms to contribute to various components. Just the tunnel is 2.5 kilometers in length, stretching under the downtown core of Ottawa. Tunnel boring machines were utilized to create the tunnel.

 

It takes a team to tunnel.

Utility coordination for three separate electrical services was located at three different locations along the tunnel. We were responsible for designing the 15kV and 600V distribution for each tunneling site, as well as assisting in the design and specifications of the portable underground substations. The distribution for the tunneling and mining equipment included ground fault and ground check systems for the underground equipment, as well as 600V distribution for all surface equipment related to the project. 

Smith + Andersen also designed the emergency power distribution at each site, providing design and coordination for the surface and underground illumination, and coordination with the design teams for the stations.
