Correction on first use of BubbleDeck

Our Headline News article “Floor slab embedded with balls used at Montreal engineering school residences,” dated March 25 referred to Teknika HBA of Montreal as the first engineer in Canada to use BubbleDeck Technology. BubbleDeck  is a prefabricated floor slab system with embedded large plastic globes in a steel reinforcing mesh.

Teknika used the BubbleDeck system in a large 15,000-sq.m residential building at the École de technologie supérieure in Montreal last year.

In fact, however, the system was used earlier than that by Read Jones Christoffersen in Vancouver. They used BubbleDeck for the floors in a  section of a renovated building for the Child Adolescent and Women’s Mental Health Building in Vancouver in 2006.

An article in Civil Engineering dated December 2005 said that BubbleDeck first made its appearance in the Millennium Tower in Rotterdam, the Netherlands, and has since been used in hundreds of buildings in Europe.
