Investigators say poor oversight allowed a New York City payroll-technology project to spiral into a $700 million tangle of contractor fraud, budget overruns and delays.
A Department of Investigation report released Friday says the city lacked proper management safeguards to detect and prevent the problems with the CityTime project.
Its costs ballooned from about $70 million to $700 million. Authorities later concluded a key contractor hired and overpaid consultants through companies his associates owned.
Eight people have been convicted or pleaded guilty. The prime company on the project repaid the city more than $500 million.
The Department of Investigation recommends assigning an "integrity monitor" to all major technology projects. It also wants to require consultants on such projects to undergo conflict-of-interest background checks.
The mayor's office had no immediate comment.
