Vancouver Stadium

(OP)
VANCOUVER — A combination of natural causes and human error led to the roof collapsing at B.C. Place stadium, general manager Howard Crosley said Friday.
He said a preliminary report showed weakened fabric, a rapid pressurization of the roof and heavy wind conditions caused the structure to tear.
A B.C. Place employee quickly increased the pressure on the roof last Friday after staff noticed it was slightly inverted during a heavy wind and sleet storm.
At the same time, another person turned on an additional eight fans to keep the air-supported roof inflated.
"The staff reacted as they're trained to do," Mr. Crosley said. "Which is, when they noticed a depressurization in the facility, to apply pressure. The mistake that was made was that two people were operating the controls at the same time."
Engineer Kris Hamilton, who is conducting a report of the incident, said there was three times more pressure on the roof than there was supposed to be.
