Interior to Lower Mainland (ILM) Transmission Project

248 km
transmission line

500 kV

Largest
transmission project undertaken by BC Hydro in 30 years

Challenges

Strengthen the transmission system from the Northern and Southern Interior of the province to the Lower Mainland and Vancouver Island, delivering clean, reliable power to customers.
Construct a transmission line approximately 248-kilometers long, traversing some of BC’s rugged Coastal Range mountains and rising to an elevation of nearly 1,830 meters.
Modify two existing terminal substations and construct a new series-capacitor substation to help maintain voltage levels across the long transmission line.

Working in an integrated team with BC Hydro and other external consultants, carried out construction program management services.
Acted as BC Hydro's representative to manage the design-build contracts for implementation of the project.
Ensured quality objectives were met by performing audits on each contractor, verifying conformance to contracts and in accordance with BC Hydro's quality management systems.
Helped BC Hydro oversee project execution, to ensure problems were being discovered early, corrected adequately, and prevented from happening again.

The project included 248 km of 500 kV transmission line using 4-bundle conductor.
We helped BC Hydro roll-out its new suite of project-controls applications for monitoring, control, and reporting on project progress.
This was the first major BC Hydro transmission project to be administered using this new state-of-the-art project controls system.
