Chairman of the OPW John Conlon revealed the figure at the Oireachtas Finance Committee, where he has been answering questions on the cost of the contentious bike shelter.
Mr Conlon said the installation of the security shelter followed an extensive consultation with gardaí and included significant mechanical, electrical and security considerations.
He said there were also significant underground, ventilation, CCTV and other costs “there was a huge security element”, he said.
