Engineering Feats: Building a Supertall in Toronto
Constructing a supertall building in Toronto’s urban core presents unique engineering challenges, from managing wind loads to ensuring structural stability on a complex urban site. One Bloor West’s structural system is a marvel of modern engineering, utilizing a reinforced concrete core with a system of mega-columns and outriggers that distribute loads efficiently while maximizing usable interior space.

Given Toronto’s cold climate and variable soil conditions, the building required an innovative foundation system, with deep caissons extending into the bedrock to anchor the immense structure securely. Wind tunnel testing and computational fluid dynamics were employed extensively to ensure the tower’s slender form could withstand high-altitude wind forces while minimizing sway, ensuring occupant comfort.
