B.C. Place probes dome collapse

Officialsat Vancouver's B.C.Placeare searching for answers after the stadium'sinflated dome roof — destinedforthe spotlight in the 2010 Winter Olympics — collapsed on Friday.

With a sound "just like thunder," theTeflon-coatedroof fell, leaving the torn fabric hanging over the Vancouver landmark and a giant hole in the city's skyline.

B.C. Place officials said the collapse was an intentional controlled deflation after one panel of the roof was torn off.

However, general manager Howard Crosley told a news conference Friday afternoonthat itwas still not known what caused the initial problem.

"At this particular point in time, we're still assessing what that was. We also conducted a standard evacuation of the facility in the interest of public safety."

'Like elephants running through your living room'

Two City of Vancouver workers told CBC News they heard the fabric flapping, followed by what sounded like an explosion, ripping a hole in the inflated roofof the building that is to host the opening and closing ceremonies for the 2010 Winter Olympics.

Part-time stadium worker Trevor Holnesswas inside the facility during the noon hourwhen he noticed that the roof was sagging.

He said he was warning other workersabout the possible danger when "huge gusts of wind caughtthe slack in theroof, and it was an intense sound."

He described it as the sound of "elephants running through your living room. It was thunderous."

Holness said there was a seven-metre tear in the roof that "grew across the bottom and travelled up one side, and there was like the whole corner flapping, the sound was insane."

Paul Walker, who was also working inside the stadium, told CBC Radiothe tearsounded "just like thunder." He said that the air in the dome then started "beingsucked out really fast."

He said water started pouring down from the hole in the roof. It had been a snowy, rainy day in B.C., but there's no word on whether that was a factor.

There were no reports of any injuries.

Crosleysaid a new panel to repair the roof has been ordered. But he could not say when the roof will be repaired and the dome re-inflated.

Poor maintenance cited by NDP

The New Democrat MLA for Delta North says a lack of proper maintenance may be to blame for the roof collapse.

Guy Gentner first raised the issue in the legislature last May, warningthe roof was in bad shape.

"B.C. Place Stadium is close to its end. The roof is ready to fall down, according to the service plan. Its anticipated lifespan is coming to an end. Could the minister tell us when the life-cycle replacement is due on the roof at B.C. Place Stadium?"

Olga Ilich, who was then the tourism minister,offered this reassurance.

"Apparently the roofis expected to last another 15 to 20years if it's maintained properly in its current state," she told the house.

She also confirmed that it costs more than $300,000 a year to maintain the roof.

The stadium, which is home to the B.C. Lions football team, seats 60,000 and wascompletedin 1983, three years ahead ofExpo 86. It has been the largest air-supported stadium in the world.
