Nearly half of Opal Tower's 169 apartments remain unlivable four months after cracks began to appear in the $165million building - and work to fix the defects has only just started 169 of the 392 apartments still aren't ready for residents to move back in The owners' corporation formed deal with Icon and its Japanese parent company The building company Icon is set to extend the warranty on the 36-storey tower Building company has spent more than $10 million reimbursing residentsBy Alana Mazzoni For Daily Mail Australia Published: 17:05 BST, 14 April 2019 | Updated: 17:08 BST, 14 April 2019 Viewcomments Residents still can't move back into almost half the apartments of the Opal Tower - more than three months after hundreds of residents were evacuated. The final rectification works on the tower at Sydey Olympic Park have only just gotten the go-ahead, despite being expected to start last month, The Daily Telegraph reports. A spokeswoman for building company Icon confirmed 169 of the 392 apartments still aren't ready for people to move back in. More than 200 residents of the high rise were evacuated on Christmas Eve last year, when cracks found in the building sparked fears it could collapse. More than 200 residents of the Sydney Olympic Park high rise were evacuated on Christmas Eve last year, when cracks found in the building sparked fears it could collapse The building's owners' corporation has formed a deal with Icon and its Japanese parent company Kajima Corporation to extend the warranty on the 36-storey tower. This is meant to give residents peace of mind and make sure they're covered if any other faults in the building are detected in the future, according to the Owners' corporations chairman Shady Eskander. A statement is set to be released on Monday with the exact details of the warranty, as well as any other deals they have struck up with Icon. A spokeswoman for building company Icon confirmed 169 of the 392 apartments still aren't ready for people to move back in (pictured: residents being offered information two days after they were evacuated from the Opal Tower) It's understood Opal Tower is currently covered under warranty for seven years. So far, residents have been moving back into the tower gradually, with some allowed to return, while others have been back in their homes since January. In the four months since the mass-evacuation, Icon has spent more than $10 million reimbursing residents for accommodation and living expenses since December 31, according to an Icon spokeswoman. Icon has been offering allowances of between $220 a day for one-bedroom apartments and $500 a day for two bedroom apartments. The news comes nearly two months after footage captured by a whistelblower three years ago and obtained by A Current Affair, captured the bungled building work inside the tower, which has been dubbed as 'patch up job' by an insider. In the video an abundance of negligence's were recorded, including one concrete slab between the tenth and eleventh floor which is riddled with cracks. The severe cracks were patched up with filler, while the supporting pillars also appear to be crumbling. But rather than use the filler as a temporary fix, it's believed the area wasn't cut out and replaced but rather the filler held the cracks together while a further 20 storey's were built on top. The final rectification works on the tower at Sydey Olympic Park have only just gotten the go-ahead, despite being expected to start last month An interim report, commissioned by the New South Wales Department of Planning, suggested design and construction problems were the most likely causes of cracking in the apartment building at Sydney Olympic Park. The interim 17-page report ruled out bad weather and poor materials for building faults in the complex with 392 apartments. It instead recommended that steel hob beams, used to reinforce concrete, be repaired and strengthened.
