Canada Line

Canada Line
Date: 2007

In preparation of the 2010 Winter Olympics in Vancouver, Canada Line was one the key infrastructure projects undertaken by the Government of British Columbia. The $ 2-billion project comprises 19.2 kilometres of track, with the main line linking Vancouver to Richmond, and a 4 km spur line from Bridgeport Station connecting to the Vancouver International Airport. General Contractor SNC Lavalin selected Agra for the construction of unique guideway foundations along the Richmond corridor and YVR Airport. The AGRA Foundations Limited team installed 1600 modified expanded-base piles along busy traffic roads in Richmond and the airport area.

Solution:

AGRA proposed a modified expanded-base pile system to support unusually high loads of the guideway structures that also allowed for increased moment capacity of the foundations during seismic events. Involved in the early design phases of and development of the modified system, including 600-tonne load tests in December 2005 for assessment and evaluation. This unique and innovative foundations system, eliminating deep pilings and extensive ground modifications that would have been required by alternative methods, presented significant savings to the client.
