In his report, Mr Lim also took the Singapore Tourism Board to task for spending $1.51 million over seven years on feasibility studies, maintenance and reinstatement works to turn Capitol Theatre into a performing arts venue, only to find that it was not a viable project.
The building stood vacant until it was returned to the Singapore Land Authority last year. Mr Lim reckoned the rental revenue foregone to exceed $280,000 a year.
The report also highlighted the lack of transparency in the calls for tender bids and irregularities in payment.
One such irregularity was serious enough to have been referred to the police for investigation.
Acting on an anonymous tip-off alleging favouritism in the awarding of contracts to redevelop the Singapore Discovery Centre (SDC), the Auditor-General's Office found irregularities in 92 per cent of the contracts awarded to one contractor and another company with links to the contractor.
As the SDC - which promotes national education here - is related to the Ministry of Defence, Mindef referred the matter to the police in April.
Contacted last night, Mindef said investigations were still underway.
