Inhabitants of Sydney Opal Tower stand for more uncertainty after an interim report stated structural beams are defective.
The Department of Planning document from New South Wales has made a series of recommendations to the battered 36-storey residential tower at Sydney Olympic Park.
It does not say when residents of the newly built West Sydney complex could go back four weeks after their evacuation on Christmas Eve.

Residents of Sydney's cracked Opal Tower saw more uncertainty after an interim report in the building failed to find whether it was safe for people to go back to
The Opal tower with 36 floors of Sydney had previously been evacuated twice because of the cracks in the concrete panels (pictured)
The 17-page interim report published on Tuesday has shown that various factors may have contributed to the building's problems, but excluded extreme weather conditions and unreliable materials.
Instead, it called problems with the beams of the fireplace and advised to repair and reinforce them.
"Further analysis should be carried out on the structural design of the hob bars and associated structural members with similar details and attention should be given to their reinforcement where they occur throughout the building," he said.
The independent report from the Unisearch group of engineers found that the building is structurally sound, but requires significant rectification work.
& # 39; Although we have isolated the likely cause of localized structural design and construction issues, we need more information to draw definite conclusions about the cause or causes of the damage, "the report said.
& # 39; More work is needed before we can make recommendations on what to do to prevent such incidents in the future. & # 39;
The team of professors, who visited the site several times during their research, suggested to check a number of things before the major rectification work begins and residents go back inside.
We recommend that independent and qualified structural engineers be called in to review the final proposals in detail before the main rectification work begins, they said, adding that it is difficult to say how long that might take.
Another theory states that the joints – a dense liquid of water, cement and sand mixtures that were used to fill openings – led from both the panels and the support beams to the cracks.
Reports were handed over to the Minister of Planning Anthony Roberts about the specifications that Icon Co, the builder of Opal Towers, followed.
The research team includes Rincovitch Partners, WSP, a third party hired by Icon and engineering firm Cardno.
The New South Wales government has also appointed Dean of Engineering Mark Hoffman and University of Newcastle's John Carter School of Engineering for research at the University of New South Wales.
Approximately 300 people were forced out of Opal Tower on Christmas Eve after a loud noise was heard and a large crack appeared in a panel on the tenth floor
All parties involved in the investigation have approved a plan for restoration and re-occupation of the building.
Some residents have returned to Opal Towers, despite the advice to stay clear until the cause of the defect has been determined.
Approximately 300 people were forced to leave the brand new high-rise building in Olympic Park on Christmas Eve after a loud noise was heard and a large crack appeared in a panel on the tenth floor.
