Tradie, 18, killed in scaffolding tragedy
UPDATE: The 18-year-old who died after a 17-metre tall scaffolding structure collapsed on top him at a building site in Sydney has been remembered by friends as an "angel" who always looked after everyone.
Teenager Christopher Cassaniti, an apprentice formworker, and another 39-year-old man became trapped beneath a mountain of twisted steel and cement bricks after the horror accident at a development project on Epping Road in Macquarie Park earlier just after 12.20pm today.
More than a dozen emergency crews rushed to the "nbh" at Lachlan's Line construction site - a mixed-use residential and commercial development project - and managed to free the older man after an hour. He remains in a critical condition, Sydney's Royal North Shore Hospital has said.
Rescue workers continued a "delicate" operation to Christopher but struggled to reach him due to the sheer amount of debris. He was pronounced dead at the scene.
Family friend Damion King, 16, said they had only just been celebrating Christopher's 18th birthday on the weekend.
"My dad called my sister first and she called my mum and she just started crying," Mr King told news.com.au.
"That's when I found out and 30 minutes later his brother posted RIP Chris. It's really sad.
"We used to go on holidays together. He always looked after everyone, he was very kind.
"He just bought a car and was just starting his life. It's so sad to see him lose everything."
On Facebook, family friend Bella Mineo said she would "always love" her friend Christopher.
"Today I am crying because I have lost a person who occupied a very special place in my heart," she said.
"You have been my friend since the first day of kindergarten. Words can't express how much this hurts. You were full of positivity, always smiling, always seeing the best in everyone. You are an angel. It hurts me that someone so precious had to pass. Forever in my heart."
Darren Greenfield, state secretary of the construction industry union CFMEU, said Christopher's distraught parents arrived just before police confirmed the tragic news of his death.
"As you'd expect, they're devastated to lose their 18-year-old son," Mr Greenfield told news.com.au.
"He's new to this industry, early in his working life. To lose his life doing a job is atrocious."
It's understood the man's mother worked in a food truck that visited the site daily.
EARLIER: One man is in a critical condition and another remains trapped beneath a mountain of debris after "a large amount" of scaffolding collapsed at a building site in Sydney.
More than a dozen emergency crews rushed to Epping Road in Macquarie Park just after 12.20pm after the accident.
Two workers were trapped beneath the rubble in what has been described as "a scene of panic" and an "absolutely chaotic" situation.
A witness told 10 News he was eating his lunch next to the site - the Lachlan's Line mixed-use residential and commercial construction project - when he heard a loud crash and saw people fleeing.
The man told the network it was a "scene of panic" as other workers realised people were stuck beneath piles of twisted metal and concrete.
It's believed the scaffolding was up to 15-storeys tall and was in the process of being removed as the project nears completion.
One man was freed at about 1.30pm and rushed by ambulance to Royal North Shore Hospital in a critical condition.
A second man remains trapped beneath the debris and is also in a critical condition, with rescuers working to reach him.
Steve Vaughan, acting superintendent of NSW Ambulance, said it was an "absolutely chaotic and emotionally charged scene".
The men had sustained "significant" injuries, he said.
A number of other workers had been trying to help their trapped colleagues in the aftermath, Mr Vaughan said.
Firefighters earlier described the rescue operation as "delicate" and deployed seven crews, including a team that specialises in structural collapses.
Three teams of paramedics and a Care Flight Rescue Helicopter are also at the scene.
In a statement, construction company Ganellen said it's assisting emergency workers at the site of the $220 million development.
"Our immediate concern and focus is on the safety of our people and according for those who were in the vicinity of the accident, and ensuring the site is safely secured," the builder said in a statement.
As the operation is continuing, members of the public are urged to avoid the area. Two eastbound lanes, including the left turn lane, are closed on Epping Rd at Delhi Rd.
Safe Work New South Wales is sending investigators to the site, it said.
More to come.
