A sinking and tilting skyscraper in San Francisco is now at risk of a major cladding fire, according to a report.
The investigation looked at the safety of the 58-storey Millennium Tower, which in March of this year was found to have sunk 17 inches (43 centimetres) and tilted 14 inches (36 centimetres) since completion in 2008.
It found that the movement had dislodged the curtain wall away from the main structure, leaving a gap where smoke and fire could quickly spread.
Engineering company Allana Buick & Bers, who conducted the enquiry, drew the conclusions after looking at two areas of the building's facade. But the company said the suggested that the same was likely to found across the entire structure, endangering the lives of its residents. "These openings represent a breach in the fire and smoke safety barrier, which is a life and safety hazard to the occupants," it said.
Investigation prompts further action
Allana Buick & Bers was commissioned to produce the report by the homeowner's association, on behalf of the tower's occupants.
Its findings were picked up by San Francisco news channel NBC Bay Area and ? in light of the fatal recent fire at Grenfell Tower in London ? have triggered alarm.
