Alistair Bidmead (pictured) was a professional stone mason with almost 20 years in the business before he was trapped and killed by falling debris on a Petersham school site
A migrant English craftsman has been named as the stonemason who was killed when 'several tonnes' of scaffolding and bricks collapsed and crushed him on Friday.
Alistair Bidmead was working on the façade of a building when the tragic accident occurred at Fort St High School at Petersham in Sydney's inner west.
The stonemason, who owned Bidmead & Co based in Fairlight on Sydney's northern beaches, died while working on the third storey of the school's main building.
NSW Ambulance Inspector Michael Corlis said attempts to resuscitate Mr Bidmead were futile.
'His injuries were [such] he could not be resuscitated ... unfortunately there was nothing we could do,' Inspector Corlis told 9News.
It is believed a façade broke loose from the structure before collapsing on top of him at 11am, with a number of workmates witnessing his death.

A crane was brought in five hours after the accident to remove the colossal slab of masonry and heavy rubble that crushed Mr Bidmead, originally from the Cotswolds in Gloucestershire.
His body was found among the twisted scaffolding and debris.
The tradie was a classically trained stonemason whose business did restoration services on heritage buildings and constructed new stonework too.
He had been in the business for more than 16 years, undertaking and managing projects in both Australia and the UK.
No children at the school witnessed the horrific freak event.
The education department and the school declined to comment.
A crime scene was established with police and Safe Work Australia investigating.
