Chairlift towers at Blackcomb-Whistler should be equipped with drain holes to prevent water from amassing within, according to a B.C. Safety Authority (BCSA) report released yesterday.
It contained the results of an investigation into the collapse of one of the Excalibur Gondola’s towers on Blackcomb Mountain in December 2008.
According to the document, the tower’s failure was triggered by water that seeped into the structure’s central cavity and then expanded while freezing. The resulting collapse wounded 12 passengers and damaged six cabins.
The report’s five other recommendations have to do with ensuring proper communication, documentation and awareness between construction contractors and officials.
