Dufferin Jog Elimination - HCM Group

Caissons, Micropiles

Dufferin Jog Elimination

This project involved the extension of Duffering Street under an existing CN rail line and through the abutment wall of a century old CN bridge at Queen Street in Toronto. HCM performed a design-build tied back caisson wall solution for the main staging effort.

The geology of the soils was a combination of fills and wak silts over rock. The old bridge was jacked onto tower frames supported by cased micropiles. Low headroom caissons were installed by churn drilling with permanent liners. Further innovation included a tieback connection through abutments which avoided damage to the future surface of the structure.

HCM met scheduling requirements while performing several services throughout multiple phases, facilitating overall project success.
