MONTREAL, QC
Deloitte Tower
The first privately funded commercial development built in downtown Montreal since the early 1990s, the 26-storey Deloitte Tower was completed in 2015.
The Deloitte Tower is nestled between the historic Windsor Station and the Bell Centre.
The project incorporates a portion of the heritage Bush Shed structure into its design.
Unique open roof screens conceal rooftop services and cooling towers from view.
The tower also includes an open atrium space with a cantilevered feature stair through the floors used by Deloitte, three levels of underground parking adjacent to the tower, street level retail space, and supporting building service spaces.

KEY CONSIDERATIONS
Challenge One
Structural elements must accommodate design choices, such as access floors, tight floor-to-floor heights, the Bush Shed structure, and a passenger drop-off area at street level.
Solution One
The reinforced concrete structure incorporates a unique two-way slab band floor framing system. This economical design accommodates columns that slope through the height of the tower. Columns vary in strength from 60 MPa to 80 MPa and use 500 MPa reinforcement to reduce column size and increase the rentable floor area. Other sloped columns avoid the Bush Shed structure and a passenger drop off area at street level.
