Some residents have returned to a brand-new high rise in Sydney that was evacuated on Christmas Eve after cracks appeared on the 10th floor, but 51 of the units were still deemed unsafe on Tuesday.
Emergency services have said there are no longer fears the Opal Tower could collapse, after loud cracking was heard by residents in Sydney’s Olympic Park on Monday afternoon.
About 300 people were evacuated on Christmas Eve, but Fire and Rescue New South Wales said two-thirds of the building’s 392 units were now safe.
The superintendent of Fire and Rescue New South Wales, Adam Dewberry, did not expect those units to be declared safe any time soon.
“It’s not as if it’s going to be tomorrow or the next day because there needs to be an element of work done, now it’s just how quickly that work can be done by the engineers to get in and get a really good thorough assessment,” Dewberry said on Tuesday afternoon.
He said authorities weren’t yet aware of how many people were affected.
“The actual number we’re not sure of, because of the time of year, because of the evacuation and people have sorted out their own accommodation and got themselves moved on.”
Dave, a resident of Opal Tower, told Guardian Australia his apartment was one of the 51 still affected.
“My apartment and my neighbour had notices on the doors that said you can’t actually live in here,” he said. “Nobody else was affected, it was just that corner.
“Yesterday at about two o’clock I left my place to go to my parents’ place for Christmas. When I arrived, I got a text from a friend saying ‘Hey are you OK?’ She has a friend that is a couple of floors above me who said they got evacuated.
“I woke up at about six this morning and drove over there. There was a security guard there, I explained my situation, he said ‘OK you can go up and get your stuff, you only have five minutes.’”
Dave said he had lived in Opal Tower since the start of August, after the building was opened earlier this year. He said the tower was 80% to 90% occupied, based on his rough estimate.
“The building strata management have been providing updates via email – not as detailed as I would like – but given the circumstances they are doing well. The builders and the developers are where my frustrations are at.”
Opal Tower, built by developer Ecove, was completed this year. Authorities said there had been no previous reports of cracking in the building.
A spokesman for Ecove said the company was “deeply sympathetic” for the concern and anxiety residents had been put through.
In an email seen by Guardian Australia, Waterpoint Management told residents the fault affected 35 floors of the building.
“This is due to a fault in a support wall in the building affecting floors ground to 35 on your side of the building,” it said. “Costs for places to stay will be attempted to be recovered by the responsible parties.”
On Tuesday morning Dewberry said people had first noticed the issue because the door jambs of the building shifted and residents couldn’t open their doors.
Police evacuated the building, including 55 children from its childcare centre, and a 1km exclusion zone was put in place.
On Monday, NSW police said the building had shifted between one and two millimetres – but there had been no further movement detected.
