Westcoast Transmission Building

The Westcoast Transmission Building consists of a twelve-storey dark-glazed rectangular tower suspended by cables from a central concrete entry/elevator core. It is prominently located on a multi-leveled plaza on the north side of West Georgia Street in downtown Vancouver.

The Westcoast Transmission Building is significant for its historical, technical and aesthetic values, most notably for its unique cable suspension system of construction. This system was a widely-endorsed response to increasing seismic design requirements, and makes the building one of Vancouver's most identifiable landmarks in the downtown core.

Constructed in 1968-69 for the Westcoast Transmission Company Ltd., this landmark building is indicative of the continued expansion of Vancouver's central business district during the corporate building boom in late 1960s and early 1970s, which was fuelled by the transfer of corporate headquarters to Vancouver. Resource development companies such as the Westcoast Transmission Company, incorporated in 1949 by a Special Act of Parliament to build British Columbia's first gas-processing plant at Taylor, British Columbia, and Canada's first large pipeline, are particularly representative of the city's corporate expansion.

The building exhibits the Modernist interest in structural innovation and technology. Its dramatic suspension bridge construction facilitated a continued view of the North Shore from Georgia Street, but more importantly, symbolized to the public a corporate response to severe earthquake hazard. Its simple glazed curtain wall box draws attention to the structural innovation, which garnered international recognition as the recipient of the 1970-71 Design in Steel Award from the American Iron and Steel Institute.

The building's structural consultant, Bogue Babicki, of the architecture firm of Rhone and Iredale, is representative of the convergence of European engineering and design expertise with local design challenges, facilitated by the post-WWII immigration of professionals schooled in the European experimental approach.
