BCE Place: Heritage Square and Galleria

Toronto, Ontario

Santiago Calatrava Architect

Construction: The Galleria

The galleria is intended to appear as a free standing structure - - each column lightly tied to the structure behind for added lateral stability. The galleria is approximately 350 feet in length, with columns at 45 foot intervals. The overall height is 90 feet. The columns spring from the floor as a single structural steel element, branching initially into 2 at 22 feet, then into 4 at 48 feet above grade. The roof system is a space frame attached both to the columns and to the buildings behind.

The Galleria roof was constructed of V-shaped, curved steel frames that spanned across the space. They came to be called "canoes". The canoes were too large to ship down the congested narrow downtown streets to the site. The rib pieces were constructed in the shop and shipped to the site for final assembly. There were identical jigs in the shop and on the site for accurate assembly.
