Some work on Dublin City Council's affordable housing project on the Oscar Traynor Road in Coolock has been paused due to their failure to comply with building regulations.
In a report to Dublin City Council, City Manager Richard Shakespeare said that during routine inspections by the Building Control Authority of the Council, concerns about compliance with some building regulations were raised with the developer Glenveagh.
The report said: "The works were not progressing in a workmanlike manner in accordance with the requirements of the building regulations.
"It is essential that where defects are identified that they are dealt with with promptly and comprehensively."
He said the issue was followed up on in writing and that the developer is engaging with the process and investigating "to identify all potential issues including pausing of some works to allow for these investigations to be carried out"
The report says technical submissions have been made to Building Controls section of the council in response to the concerns raised and discussions are ongoing with the developer to agree what works are required to rectify non compliant work.
It also says these will have to be carried out in a "timely" manner by Glenveagh.
The city manager said that due to the scale and importance of the development, the Building Control Authority has prioritised inspection of the site and will continue regular inspections "to ensure adequate public oversight is provided and provide the necessary confidence that the requirements of the building regulations will be achieved."
Mr Shakepeare said he understood that increased resources have been provided by Glenveagh in terms of supervision and site management and he said this was welcome.
He concluded the report by saying that the Building Control Authority of Dublin City Council has strong powers of enforcement and deploys these powers where necessary and proportionate to ensure compliance with the requirement of the building regulations.
Last year, the Coolock development attracted controversy when it was revealed that homes in the housing scheme were significantly higher than expected, with the price of a three-bedroom home up to €475,000.
Dublin City Council signed off on the deal for the redevelopment of the land, which is located near the Port Tunnel, in November 2021 following a number of years of difficult negotiations.
It agreed that the developer Glenveagh Properties would build 853 homes, 40% for social housing, 40% for cost rental and 20% for low and middle-income workers qualifying for the affordable purchase scheme.
The first phase of the development opened for applications in July.
Dublin City Council said the houses at Oscar Traynor Woods were being offered at between 18% and 21% below the open market value.
