Senior officials involved in the upgrade of Parliament House's security doors had no idea about allegations a subcontractor was using drugs, a federal inquiry has heard.

Department of Parliamentary Services secretary Robert Stefanic told a Senate hearing on Monday the media reports about Steelvision owner David Gooley prompted a meeting with officials and builder Lendlease.

Mr Stefanic said no one was aware of any “lifestyle” or other matters until they were raised in those reports, which Mr Gooley has denied.
