The Buildings Department is investigating a March 10 crane accident on Staten Island that resulted in the death of a worker at a union construction site.

Antonio Veloso, a 54-year-old Portuguese immigrant and member of the Laborers International Union Local 1010, was killed at 356 Meredith Ave. after being struck by a load that had fallen off a crane.

The Empire State Chapter of Associated Builders and Contractors, which represents nonunion contractors, raised concerns to Buildings Department Commissioner Rick Chandler that there was less public outrage over the accident at a union job site.

A Buildings Department spokesman confirmed the probe.
