Building company Icon has promised a thorough investigation to get to the root cause of the collapsed structural panel on tenth floor of the Opal Tower.
The 34-storey building is only 18 months old.
Complaints of a 'cracking sound' prompted an evacuation of 3,000 people in the surrounding area on Christmas Eve.
Icon director Julian Doyle said the investigation could go beyond 10 days, leaving residents concerned about their living arrangements and costs over the coming weeks.
"For us, the secret is getting the answer and determining what we need to do to not replicate what happened on level 10 and implement that as quickly as possible."
