A breakdown of costs also shows the reviews commissioned by Health Secretary Jeane Freeman to establish the extent of the problems at the replacement building cost £500,000.
Ms Freeman ordered a halt to the opening of the £150m new hospital at the beginning of July just days before it was due to open. The move came after last-minute checks found the ventilation system in the critical care unit did not meet national standards. Checks then revealed remedial work was also needed in the water and drainage systems.
Now the Sick Kids will have to remain in its current building at Sciennes until next autumn and the Department of Clinical Neurosciences will stay at the Western General Hospital until spring next year.
Ms Freeman told MSPs last month that the delay was expected to cost an extra £16 million on top of the £1.35m a month being paid by NHS Lothian to the consortium which built the hospital.
Dual running of the two sites will cost £1.5m, while additional maintenance at the current sites is shown as £2m; and additional investment in current facilities and equipment is estimated at £3.7m.
In addition, project team costs are £1.5m; additional project support £550,000; legal, technical and financial fees £300,000; and the independent reviews £500,000.
Ms Freeman added: "These estimates will be refined as plans are further developed. I will keep members updates on costs as work proceeds on resolving the current situation."
Lothian MSP and Tory health spokesman Miles Briggs said: “This breakdown of costs of the £16 million extra that is needed to build the new Royal Hospital for Sick Children shows the extent that this failure is going to cost the public.
