Alberta Utilities Commission - East Alberta Transmission Line - Converter Station

Location -

Brooks, AB

Project Start Date -

April 2013

Project Completion Date -

November 2014

Four Seasons was hired as the primary civil contractor overseeing development of a 100-acre site as a converter station for the east Alberta transmission line. This would require cleanup, filling and grading over an area larger than 400,000 square metres, as well as construction of various structures and installation of several support systems.

Key challenges for this project included:

  • Challenging deadlines. Four Seasons increased the equipment and manpower loading to ensure the grading works would be complete in time to accept delivery of sensitive transformer components arriving from overseas.  
  • Isolated location. The remoteness of the location, more than 150 km from the nearest major settlement, required detailed planning, scheduling and logistics. This included flying in work crews as well as equipment and materials.
  • Extreme weather. The cold winter temperatures and extremely changeable conditions presented an additional element of uncertainty that had to be factored into site design and work planning.
