Cracks in Opal Tower ‘started three years ago’
A WHISTLEBLOWER who claims to have been involved in the construction of the Opal Tower said there was up to 20 metres of cracks in one floor and plastic stuck in a supporting concrete pillar.
An alarming video has emerged of the construction of the maligned tower which was evacuated in November, that show cracks in the roof of the 10th floor, A Current Affair reported on Monday night.
The whistleblower who filmed the footage said the cracks started three years ago.
"We could see daylight from floor to floor," he said.
"You could drop a two-inch nail straight into the floor below. We thought the actual floor should have been cut out because it was not two or three metres of cracks it is 20m."
The cracks were filled with concrete and another 25 storeys were built on top, the whistleblower claimed.
There were also issues with a supporting pillar which had a sheet of plastic stuck through the concrete that was drilled out then replaced with more concrete filler," he said.
More than 300 people had to evacuate the tower when residents saw and heard a large crack. Residents of nearly 100 apartments were given the green light on Sunday to return to their units.
