Calgary’s Brookfield Place towers over most of its neighbours. The 56-storey East Tower is Western Canada’s tallest building, second only to Toronto’s First Canadian Place in all of Canada.
It’s anticipated that the East Tower (phase 1) will be joined by a 42-storey West Tower. When complete, the two towers will be connected by a ground floor and mezzanine space contained in a 63-foot-high Winter Garden Pavilion.
The development connects with neighbouring buildings via Calgary’s +15 pedestrian walkway. Both the ground floor and +15 levels feature lobby and retail space.
The tower contains reinforced concrete cores with structural steel floor framing and exterior columns. The below-grade structure consists of reinforced concrete columns, slab and wall construction. Crews demolished sections of underground parking nearby to accommodate the East Tower’s footprint and five-storey basement, a hole that took five months to excavate.
The building envelope systems on the East Tower include unitized curtain wall with curved conical corner glass, structural glass wall systems at the crown and ground floor spaces of the building, and insulated metal cladding systems. The Winter Garden Pavilion is a jewel box-like structure consisting of glass walls and roof softened by rounded corners and edges. Mullion sections measuring 13 inches by 3 inches support the pavilion’s glass envelope.
