The Green Party leader says he can't provide an estimate for the cost of the new National Children's Hospital.
It comes after officials revealed there are 900 outstanding claims for extra money from the builder.
Yesterday's Oireachtas Health Committee hearing on the new National Children's Hospital at the site of St James's Hospital left more questions than answers.
In particular when it comes to the projected final cost of the build.
In the Dáil this afternoon Sinn Féin's Pearse Doherty said Government needs to provide clarity.
Transport Minister and Green Party leader Eamon Ryan said the Government isn't in a position to state a final cost.
We know the project is going to go about the current 1.4 billion euro price tag, the question is by how much.
Just 1% of the 900 claims for more money from the builder have been settled - and some may be heading for costly disputes in the High Court.
