Caisse de Dépôt et Placement

Montréal, Quebec



Project Information:

The Caisse de Dépôt et Placement is a highly complex project that employed steel for a variety of reasons. The building itself was constructed on top of the Autoroute Ville-Marie, and needed to maintain a lightness of structure in addition to requiring a system that could span across the expressway. Large steel trusses were used throughout the cross section of the building to this effect.

The building also employed an new "intelligent facade". More information on the environmental characteristics of the building may be found by in the linked document. The research paper was written in 2003 by Ken Lum, a Master of Architecture student at the University of Waterloo, School of Architecture. pdf 2.6 MB

View looking out through building "cut" showing the large steel trusses that were used to both span across the Autoroute Ville-Marie as well as lighten the overall dead load of the building.

The steel trusses are left exposed along the interior faces of some of the exterior walls of the building. Here we can see the diagonal members prepped with fire retardant treatment. These will be clad with prefinished metal.
Architecturally exposed steel supports the main 9 storey wall along the atrium.

The interior walkways alongside the offices adjacent to the main atrium are enhanced by an animated overlook into the 9 storey atrium -- highlighted by the architecturally exposed steel!
