Cabinet Ministers are considering what capital projects to delay to meet the cost of the new National Children's Hospital.
100 million euro has to be found in this year's budget to make up for overruns on the hospital site.
50 million needs to come from this year's health budget - and 50 million from other Departments.
Meanwhile, the Fianna Fail deputy leader, Mayo TD Dara Calleary, is bringing a Private Members Motion before the Dáil this evening, which would require the Comptroller & Auditor General to take control of any public project that's running over-budget.
Deputy Calleary says his Bill would require the intervention of the Comptroller & Auditor General where projects are set to go 20% over budget.
