The Atrium

Victoria, British Columbia Canada

 

Project Description

Located on a one-acre site in downtown Victoria, British Columbia, Canada, the Atrium Building comprises approximately 20 000 square metres of class A office and retail space spread across seven levels, with two levels of underground parking. Its design holds aesthetic distinction, user comfort, and civic responsibility as its guiding principles. The seven-storey form is clad in pre-cast concrete panels, zinc, and glass. The proportions and façade-scaled detail responds to the historic context of Victoria’s downtown. The street-level retail and orientation of the atrium and office entries serve the specific use patterns of the site. The project has achieved a LEED Gold rating based in part through the use of passive energy saving and daylighting strategies made possible by the incorporation of an internal atrium. Green roof technology, street-edge rain gardens, and a high-efficiency envelope also contribute to the environmentally sustainable design.

Lafarge Ductal ultra-high performance concrete

Ductal® is Lafarge’s ultra-high performance concrete (UHPC) that provides a unique combination of strength, ductility, durability and aesthetics – allowing architects and engineers to create innovative designs with new shapes that are thinner, lighter and more graceful than designs with conventional concrete. Depending on the application, it is blended with metallic or polyvinyl alcohol (PVA) fibres and is significantly stronger than conventional concrete. Compressive strengths range from 150 to 225 MPa (22,000 to 33,000 psi) and flexural strengths range from 25 to 50 MPa (3000 to 7200 psi).

The façade of The Atrium, designed to curve at the corners, presented challenges for conventional systems. In order to achieve this design, the architects sought a cladding material that could form tight radial curves, rather than adapting a flat panel system, which would require cutting into small pieces and faceting.
