Ministers have been told the cost of the National Children's Hospital has increased by nearly €500 million.
It is reported the update was given by Health Minister Stephen Donnelly.
The original cost of the facility was to be around €980 million in 2017; however, it is now expected to exceed €2 billion.
Last year an Oireachtas committee heard just 27 rooms have been completed out of a target of 3,000.
The contractor BAM has also submitted over 2,000 cost claims totalling €756 million.
These were described as 'grossly inflated' by the hospital's CEO David Gunning when the National Paediatric Health Development Board appeared before the Oireachtas last July.
Of these claims, only 16 of them relate to 2,376 working days.
If BAM is successful in all of its claims, it would bring the costs to nearly €2.2 billion.
In September 2022, BAM said the building was over 70% complete and was due to open in September 2024.
Paediatricians have been told the new deadline is March 2025.
