Liberal Democrat treasury spokesman Matthew Taylor said: 'PFI is simply a different way of managing projects; the taxpayer still has to pay. PFI does not provide one extra school or hospital.'
But the council intends to bid for funding from the Scottish Executive for a PFI project - Building for the future.
Leader John Ross Scott said: 'I recognise not everyone favours the introduction of PPPs for the provision of new schools. I do believe, however, that this is the only way we are going to attract large sums of government money.'
