» The Bow  » : unique diagrid for a tall building

Événement passé
18h - 19h / du 11 au 12 avril 2010PAVILLON MACDONALD-HARRINGTON SALLE G-10, Université McGill

Designed by Foster and Partners for EnCana Corporation, the 59-storey crescent-shaped glass and steel tower, which has been dubbed “The Bow” after its shape and the river that runs near it, will be Canada’s tallest building west of Toronto at nearly 247 meters high. The building will be one of the largest commercial office developments in Canada with 180,000 square meters of floor space.

Aside wanting a distinctive tower which catered to the people of Calgary, the Design Team aimed to create a city center that offered a progressive and sustainable office environment. The end result is estimated to reduce energy consumption significantly when compared to a conventional office tower.

The lateral support system consists of a perimeter trussed tube made of diagonal grids (or a “diagrid”) which consists of six storey high diagonals along the curved north and south elevations. The inward curving southern exterior of the building allows for many of the sustainable design features, including a double glazed atrium and sky gardens located on floors 12, 18, and 24.

The presentation will describe the structural design considerations of the diagrid lateral system, some construction methods, and the unique sustainable features incorporated into the building.
