Description

Le 1000 de la Gauchetière is Montréal’s tallest building reaching 51 stories above the ground. Canam-Structures succeeded in redesigning this building, originally conceived as a concrete structure, into a gravity frame steel structure with a lateral load resisting concrete core.

Features

The building features column free floors spanning 50 feet from core to perimeter wall and saw toothed cantilevered corner office areas. A composite truss system with slab on deck was used to frame the floors and cantilevered areas. Two 50-ton, 13-foot deep transfer girders spanning 50 feet were used to support columns cut short due to the necessity of column free areas at the ground level. Smaller transfer girders were concealed in the ceiling to support the gradual tapering of the building over the last ten stories.
