Mayor denies 'cover-up' over Mascot Towers

An engineer says Sydney's evacuated Mascot Towers appears to be "moving in a downward motion" but a spokesman for the owners' corporation says it's not sinking.

The mayor of Bayside City insists there is no "cover up" from his council over Sydney's Mascot Towers, after it was revealed engineers are still waiting on paperwork that may help them pinpoint the cause and prevent further damage.

It comes after residents and owners of the units were told part of the building appeared to be "moving in a downward motion".

The 10-year-old building was evacuated on June 14 after engineers became concerned about continued cracking in the primary support structure and facade masonry.

Since then, residents of its 132 units have been forced to stay elsewhere, with costs quickly adding up as authorities scramble to determine who is at fault.

It's understood engineers have requested documents from Bayside City Council - including the original development application - but are yet to receive them.

Bayside mayor Bill Saravinovski said a formal request was only made on Thursday - a week after residents were evacuated - and noted the documents were stored at a site on the Central Coast.

But he was unable to explain why they still hadn't been retrieved.

Without the documents, it's understood the engineers are somewhat helpless to stall the building's deterioration, let alone work out what the issue is.

Mr Saravinovski insisted "there's no cover-up by Bayside City Council".

"Whatever documents we have on file will be made available," he told reporters on Tuesday.

"My understanding is that we received a request last Thursday and we're onto it; even if I have to get the general manager to drive up there to the Central Coast. Even I will drive up there."

Mr Saravinovski couldn't guarantee the engineers would have the documents by the end of Tuesday.

It comes as the tower's coordinating engineer identified a new issue along the northern and eastern boundaries of the complex.

"It appears that the building is moving in a downward motion," the latest update to owners issued on Monday night said.

The update didn't elaborate on "downward motion".

A spokesman for the owners' corporation on Tuesday said describing it as "sinking" was inaccurate.

"There has been some differential settlement resulting in the currently observed building movements, at least in part," he said in a statement.

"But any interpretation of the building sinking at present is considered to be alarmist. The building engineers are continuing their investigation and monitoring."

Differential settlement happens when a building's support foundation settles in an uneven fashion - sometimes causing structural damage.

Minister for Better Regulation Kevin Anderson said the latest update was "distressing" for residents and has requested an urgent briefing.

"Time for talk is over," he told reporters in Tamworth.

"We're very keen to get reforms in place to look at accountability, transparency and the quality of building. We're moving on getting a building commissioner appointed who will be able to make sure that we don't find ourselves in this situation again."
