Roof collapse at southeast soccer centre December 22, 2008 - 4:00 pm 660News Staff The continuous snow has caused the pressurized bubble at the Calgary Soccer Centre to collapse. No one was inside the building when the bubble came down around 3:30 a.m. The force of the collapse was so strong, the metal structure was bent. The area affected by the collapse includes three main fields, and two mini-fields. General manager Perry Logan tells 660News, nothing like this has ever happened in the previous winters, that have been just as cold and snowy. The dome even underwent a safety test in the fall. Soccer games are being rescheduled, but so far nothing has been cancelled. Engineers are investigating, and it could be a month before the dome is repaired.
