Worksafe BC is investigating after a crane reportedly collided with a power line at the Trump Tower construction site in downtown Vancouver.

A Worksafe BC spokeswoman said no one was hurt in the incident, reported at 2:37 p.m. Tuesday.

She did not confirm any details about what happened, but witnesses told CTV News that a construction crane came into contact with power lines near the site at 1151 West Georgia St.

Ryan Creamore, who works in the HSBC building across from the worksite, said he saw the crane lowering a platform when he heard a sound.

“[It] was coming down and then it was proceeded by a large bang that we could all hear,” he said. “I look out the window and there’s just a small little puff of smoke that came up.”

The incident knocked out power to some surrounding homes and businesses as well as traffic lights for less than an hour. Power has since been restored everywhere but the Trump worksite, BC Hydro said.

Creamore likened the loud bang to an incident several weeks ago at the same site, when a pane of glass plummeted from the 59 storeys up and smashed on to West Georgia Street.

Nobody was hurt in the incident, but the city issued a stop work order until a cause was determined. The developer of the tower blamed faulty equipment for the close call.

The $360-million, 63-storey Trump Tower is being built by developer Holborn Group, and is scheduled for completion in fall 2016.
