A serious safety incident has happened at a high rise residential construction site in Braddon.
WorkSafe ACT is investigating the incident.
A safety inspector visited the site following a report that prefabricated concrete panels collapsed into a lift shaft.
Reports say one panel fell approximately 7 metres into the shaft well.
Thankfully the shaft was empty at the time of the collapse and nobody was injured.
Officials are investigating the cause of the collapse and have engaged an independent engineer to assist in the investigation.
WorkSafe said it will be providing safety advice to the state and national construction industry, since the incident is a significant one.
