The board overseeing the development of the new National Children's Hospital says there's "no expectation" it'll be completed by the latest deadline.
It's also emerged the main contractor has submitted claims for extra costs worth over €200 million.
It's been beset with delay after delay - and the latest completion date for the new National Children's Hospital is August 2022.
But David Gunning from the National Paediatric Hospital Development Board says it's not looking likely that'll happen:
It led to questions from members of the Oireachtas Health Committee for clarity on what the new estimated completion date is.
The board says it won't be able to answer that question until the early part of next year.
The board says progress is still being made on the construction site, but not the progress they'd like.
