A broken glass panel on the outside of ASIO's Canberra headquarters is yet to be repaired, more than a month after it was damaged in a storm.
The glass of the Ben Chifley Building was damaged on February 12, when Canberra was hit with a severe dust storm and strong winds, a Department of Finance spokesman said.
One of the panels of the $700 million building on Parkes Way shattered during the incident, and is yet to be repaired, with a gaping hole in the building's facade still visible several weeks later.
A spokesman for the Department of Finance, the building's owner, said work was under way to replace the broken panel.
"The building has a double facade. As the panel is on the outer facade, the damage has not impacted the occupants of the building," the spokesman said.
"The Department of Finance's property services provider, Broadspectrum, is currently seeking quotes to replace the damaged panel.
"An engineer will be engaged to advise on the work."
The recent incident is not the first time the building has lost glass panels, with several of the panels falling to the ground.
In 2012, at least 19 glass panels, some almost four metres high, cracked and fell while the building was under construction.
The department spokesman was unable to say how much the repairs to the most recent breakage would cost.
However, the glass panels are estimated to cost $3500 each.
"The toughened glass panel is designed to shatter into small pieces for safety reasons," the spokesman said.
"During the weather event [in February], the glass shattered in situ and was then removed after the fact."
