Calgary New Central Library

Calgary, Canada

Calgary Library Resembling a graceful ship sailing into the future, Stuart Olson Construction relies on Doka‘s formwork solutions to create the architectural requirements of the new Central Library.

Calgary’s old library was built for a city population of 400,000 people. With the growth in Calgary and the surrounding area to almost 1.5 million people, it was time to increase the size of the library as well as modernize it.

The New Central Library located in East Village, will be 240,000 sq. ft. The challenging design, resembling a graceful ship sailing into the future, includes geometric exterior cladding and vast open interior spaces. The project, expected to be completed in 2018, will serve Calgarians for centuries.

The Challenge

The design is the greatest challenge. There is very little repetitive work on this project due to very high slabs and architectural exposed walls, columns and slabs. Therefore, most of the forming solutions are custom. Many steel and concrete components are being built simultaneously and incorporated within each other.
