Designers and builders of the Canadian Museum for Human Rights showed off their progress Friday as the museum prepares to open Sept. 20, 2014.

Scott Stirton, CEO of Smith Carter Architects, said more than 1,500 people have worked on the "world-class building" and in a Canadian first, 3-D design was used to create it. 

Officials said it's one the most complex projects ever built in Canada due to its scale, the unusual angles and the materials used.

Stirton said the building needs to be as powerful as the theme of human rights.

"The building will be, I think, quite strong as a backdrop to the stories," he said. "It's here to support the whole concept of awareness and consciousness of life as you enter and how you move towards light."

Officials said the next step is installing the exhibits.

The museum will open officially Sept. 20.
