The partial collapse of a building under demolition in Manchester sent scaffolding falling into the adjacent River Irwell on Friday afternoon.

Contractor PP O’Connor is demolishing the 12-storey Alberton House in the city centre for developer Bruntwood SciTech who plan a new 18-storey office block on the site.

Bruntwood SciTech told the Manchester Evening News: “We can confirm that this afternoon there was a partial collapse at Alberton House, which is currently undergoing a full demolition.

This is what it’s like at the moment. I’ve been told that work is now being done to “make the area safe”. Fire fighters are also on the scene. @MENnewsdesk pic.twitter.com/CMtbRClKhX

“While we appreciate the noise this generated may have caused some alarm, on a site of this complexity all eventualities are planned for meaning we were able to follow agreed safety protocols.

“As such, there was no risk to the on-site team, neighbouring buildings or the general public.

“Contractors PP O’Connor remain on site and work will continue as planned.”
