Invasive works to stop a council housing block from vibrating are on track to be completed by the end of the year.
Tenants first moved into the flats at Marchburn Park, on the site of the old Marchburn School, Northfield, in April 2012.
But last year Aberdeen City Council was forced to relocate all the residents in one of the blocks after complaints about the building constantly vibrating.
Passing cars, helicopters and children kicking balls off the building were among factors that could make the problem worse, or even something as simple as a resident running a washing machine.
The city council launched an investigation into the issue with the last resident of the six-property block finally relocated in January.
Currently, the affected block has been stripped back to the “bare bones” by contractors and, according to a council spokesman, the invasive remedial work should be completed by end the of the year.
Meanwhile, former residents have lodged a formal complaint with the council, which includes how their concerns were handled.
Mum-of-two Natalie Davidson moved into the development in 2012 with her two daughters Carly and Abbie.
She said: “The council should definitely have done more; they wouldn’t listen to us for three years.
“We have completely lost any trust in the council. We still don’t think they’re carrying out their duty of care for their residents.”
A letter from Bernadette Marjoram, interim director of communities, housing and infrastructure, said the council had investigated and upheld all three complaints made by Ms Davidson and her neighbours Sharon Munro, 44, and Alison Gray, 42.
The trio said the vibrations had caused nausea, joint pain, anxiety and headaches, and added that the council had put them through “mental torture”.
The tenants have said they are entitled to be paid for the goods they say were damaged while living in their former properties, which include household items such as washing machines.
However, the local authority has denied liability and said that any claim should be submitted to Robertson Group – the contractors behind the development.
But Ms Marjoram apologised to the tenants and said they should have received written confirmation from the council on how their insurance claim was being handled.
Ms Davidson said: “Aberdeen City Council is our landlord.
“We paid rent to the council, we didn’t pay rent to Robertson.”
The council also apologised for delays and rescheduled appointments for outstanding works which needed to be carried out at the tenants’ new homes and conceded this had “impacted” upon them.
Finally, Ms Marjoram said the council had upheld the complaint about the overall handling of the issue and said there are “improvements that should be made”.
She wrote: “The housing officers interviewed were clear that they have tried to assist and act professionally even when tensions were high.
“Officers did not demonstrate any bias against the tenants in the interviews. The actions of staff in promoting the case for additional priority to secure the current tenancies at the Council’s Housing Case Review Panel was given as an example of where officers feel they have gone beyond normal practice to assist the tenants.
“I am satisfied from the information available that the conduct of staff has been appropriate, but acknowledge the strain this has placed on relationships from both sides.
“As you remain a council tenant it is important that we accept that this has been a challenging and distressing situation but that we move forward positively to ensure that you experience higher levels of tenant satisfaction.”
The properties were some of the first council homes built for families in the city for 30 years.
The council previously said it could not speculate as to whether the issue was a fault with the construction or was due to other factors.
Ms Davidson said a worker on site told her the building could be flattened, but this has been denied by the local authority.
A spokeswoman for Robertson Group said: “We are undertaking remedial works in the affected flats and we continue to work in conjunction with Aberdeen City Council to reach a resolution to all parties’ satisfaction.”
Aberdeen City Council was unable to comment.
