Carmacks-Stewart Yukon Transmission Line

Yukon Energy

Project Summary

Challenger Geomatics provided a broad range of survey support for the construction of transmission and distribution lines between Carmacks and Stewart Crossing. Challenger supported route mapping as well the clearing and construction for both Stage I (98 km Transmission Line and 25 km Distribution Line) and Stage II; (70 km Transmission Line) and the construction of two substations for the project.

Services Delivered

  • Mapped the potential corridor using recent photography. Created Digital Terrain Model that was used to choose the route alignment.
  • Established high-accuracy GPS control networks that were used for the project.
  • Used RTK (Real Time Kinematic) techniques where appropriate to flag clearing limits. This methodology halved the project delivery time and reduced costs to the job by over 50%. Conventional line cutting was used only where RTK would not meet accuracy requirements due to timber conditions.
  • RTK GPS topographic surveys along with construction support substation design and construction.
  • RTK layout of power poles and guy wires for construction and measured as-built locations.
  • Full legal survey.
  • Precision surveys for construction of substations at Minto Landing and Stewart Crossing.
