Two men plead guilty to making several fake IDs, Social Security cards and OSHA safety course cards.   

Investigators say Michael Kruise Williams of Mamaroneck and Pedro Vasquez of the Bronx were involved in a massive counterfeit document scheme.  

Investigators found out about the scheme when a construction worker at the Javits Center had one of the fake OSHA cards. 

The Inspector General says the counterfeits put workers at risk of injury and death. 

Both men will be sentenced in October.
