INNOVATION July-August 2013

Vancouver City Central Transmission Project The Vancouver City Central Transmission (VCCT) Project is the most significant investment in central Vancouver’s electrical system in almost 30 years. The project includes the construction of a new 230/12 kV Mount Pleasant Substation in False Creek, and the construction of two 230 kV underground transmission circuits connecting Mount Pleasant to the existing Cathedral Square and Sperling Substations. Mitsubishi Canada and their subcontractor Western Pacific Enterprises recently

completed the installation of 230 kV transmission cables into Mount Pleasant Substation. Cable splicing is currently in progress, and cable terminating is expected to start in June 2013. The cable is expected to be energized later this year. The cable is BC Hydro’s first 230 kV XLPE cable installation, eliminating the risk of oil spills from oil-filled cables.

Lead cable engineer: Dr. Sudhakar Cherukupalli, P.Eng. Underground civil works: Anthony Lam, P. Eng. (lead civil engineer).

South Fraser Perimeter Road As a major component of British Columbia’s Gateway Program, the South Fraser Perimeter Road (SFPR) project is a new Public-Private Partnership (P3) four-lane route extending from Deltaport Way in Delta, BC, to 168 Street in Surrey, BC. The project is set to make a major improvement to Metro Vancouver’s road network, in an effort to solve commute congestion issues. The design team was challenged to create a cost- effective solution that would remove truck traffic from commuter roads in Metro Vancouver, while minimizing environmental and community impact. SFPR creates an efficient transit corridor that reduces congestion and truck traffic on residential connectors

throughout Delta and Surrey. This moves heavy traffic away from the places people live, increasing the quality of life for residents throughout Metro Vancouver and increasing the efficiency of commercial traffic.

Project Owner: BC Ministry of Transportation & Infrastructure. Consultant: Stantec Consulting.

Original Port Mann Bridge Dismantling The original Port Mann Bridge over the Fraser River opened in 1964. The bridge was replaced in 2012 by a new 10-lane cable stayed bridge. Foothills Bridge Co. was retained by Kiewit Flatiron general partnership to engineer a bridge dismantling plan for 30 plate- girder approach spans ranging in length from 38 m to 69 m. The elevated approach spans rise up to 44 m above the water and land, and are positioned immediately adjacent to the new bridge. Crane access, debris containment, and the stability of the partially removed structure all presented significant challenges in planning the removal operation. The bridge contains 16,500 tonnes of steel including the main span and the approaches. All of this steel is being recycled for future use. Owner: BC Ministry of Transportation. Contractor: Kiewit Flatiron General Partnership. Construction engineer: Foothills Bridge Co. (Reuben Zylstra, P.Eng; Chris Tollefson; Brandon Buder).
