Description:

This expansion will address both the forecasted increase in GO Transit ridership along the corridor as well as the Union-Pearson Air Rail Link. Because of the size and complexity of the program, Metrolinx divided work on the corridor into nine individual segments, five of which have been awarded to Hatch Mott MacDonald. The contract is for detailed design and construction management of 14.8 km of corridor, which includes 30 km of new track, numerous retaining walls, sound walls, utility relocations and, site grading and drainage. Metrolinx and Infrastructure Ontario awarded the design-build-finance (DBF) contract for the Air Rail Link in late October 2011, financial close is expected in 2012 with construction following shortly afterward.
