Sinn Fein is accusing the contractor, the Government and the Taoiseach of failing to deliver the project.
Construction costs continue to spiral to 2-point-2 billion euro.
Sinn Fein's health spokesperson David Cullinane says Simon Harris must take responsibility for the delays:
"The contractor does need to step up to the plate and deliver the project, but ultimate responsibility has to be born by Government - has to be born by the Taoiseach - who is head of a Government who has presided over this fiasco when he was Minister for Health and is now presiding over this fiasco as Taoiseach. And I think scandalizes people that this project just goes from crisis to crisis"
