Metro Vancouver’s population and economic growth is putting a strain on the city’s transportation system. With gridlock on roads and highways continuing to increase, SNC-Lavalin’s consortium, EGRT Construction, was awarded a contract to design, build and finance the Evergreen Line rapid transit project in Metro Vancouver.
The largest transit project currently underway in the Metro Vancouver, Evergreen includes elevated and at-grade guideways, a two-kilometre bored tunnel, seven stations, power substations, train operating systems, parking facilities and a vehicle storage and light maintenance facility.
Evergreen Line will also be automated and driverless, and run primarily along an elevated guideway, avoiding any potential for conflict with vehicular traffic. Travelling at a speed of 80 kilometers per hour, Evergreen’s rapidity and reliability is expected to reduce the number of single occupancy vehicles in the city. When completed in 2016, Evergreen will address these challenges by carrying 70,000 passengers every day.
By 2021, the system will remove an estimated 40,000 cars from the road every day.
A History of Innovation
Evergreen is an extension of Vancouver’s highly regarded SkyTrain network, one of the world’s first and most successful fully automated driverless systems. SNC-Lavalin’s involvement in the construction of the city’s transit network dates back to the mid-1980s, when it provided engineering services for SkyTrain’s Expo and Millennium lines, and continued with its early and on-budget turnkey delivery of the Canada Line in 2009. Evergreen will extend the existing SkyTrain system to a Canadian record of 79-kilometres by linking Burnaby, Port Moody and Coquitlam to the existing network.
Condensing 60 nights into one weekend
SNC-Lavalin recently used an innovative construction technique that allowed the work on Inlet Centre Station to take place over a single weekend, rather than 60 nights. Inlet Station was moved into its final position underneath a busy highway with a technique called box jacking. The largest maneuver of its kind in North America, a row of 30 hydraulic jacks was needed to move the 4,000-tonne concrete box. Crews were then able to begin working on the station itself, as well as the guideway, with minimal inconvenience to nearby residents. The client was delighted that the ambitious and innovative construction method was a success.
