Cases of cracking and separation were identified in Sydney's beleaguered Mascot Towers two years before its residents were forced to evacuate amid safety fears.
A dilapidation report prepared in 2017 for the developer of a neighbouring building found parts of the complex were in "reasonable-to-poor" condition.
It noted cases of cracking, material loss, material separation and efflorescence - the deposit of white crystalline salts on concrete.
Residents of the complex's 132 units have been living in alternative accommodation since being forced to flee at short notice on June 14.
It's remains unclear what caused the 10-year-old building to develop cracks in the primary support structure and facade masonry that led to the evacuation.
The builders of Peak Towers, next to Mascot Towers, have repeatedly dismissed speculation their development may have contributed to the damage.
There was a suggestion that excavations for the project, on neighbouring Church Avenue, may have played a role but construction firm Aland has previously said any link was wrong and without evidence.
A dilapidation report - prepared in October 2017 before construction on Peak Towers began - found Mascot Towers was in "reasonable" and "reasonable to poor" condition.
It found the exterior of the building was in a reasonable condition with some cracking and material loss through the walls and undersides, as well as separation through the pavement and undersides, the report says.
The interior of the basements was in a "reasonable to poor condition" with cracking and material loss throughout the walls, slabs, and underside of slabs, as well as efflorescence and material separation through the walls.
The gym and public pool were found to be in reasonable condition.
The gym had cracking through internal walls, skirtings and the ceiling, and there was found to be cracking through the pool area tiles and external walls, the report says.
The report also found the interior of the units were in a reasonable condition with cracking throughout the floor slabs, the underside of slabs and internal walls.
There was also found to be material loss through the floor slabs and internal walls, separation through the floors and underside of slabs, along with cases of paint flaking, patchwork evidence, water damage, and material displacement through the walls.
In June, Aland's managing director Andrew Hrsto said they had engineers undertake a dilapidation report of surrounding buildings, including Mascot Towers, before the construction of Peak Towers.
"This report ... clearly confirms there was pre-existing damage to the building," Mr Hrsto said in a statement at the time.
"Aland is confident the inquiry underway will demonstrate conclusively that the structural issues with Mascot Towers are unrelated to construction of Peak Towers and in fact pre-dated the commencement of construction by several years."
