A cladding taskforce in Queensland says 71 state government buildings may feature combustible material and must be investigated further.

Some 624 government buildings have been cleared and a further 121 building audits have been finalised out of 879 referred for investigation.

No government buildings pose an imminent risk to safety, the taskforce says in a status update.

About 12,000 private buildings need to be reviewed, with 10% requiring a detailed assessment, it says.

The taskforce has called for the Department of Housing and Public Works to establish a central database for information on government buildings. There is no centralised database of building approvals and construction documentation, and records do not list the type of structure built or the materials used.

In many cases cladding is considered only when building has already begun, increasing the risk that documents may not meet required approval processes, the report says.

It urges the Queensland Government to take a strong regulatory role to ensure private building owners take remedial action on cladding. The taskforce should develop education programs targeting supply chain practitioners to improve building compliance.

The report also calls for a robust fire safety standard to be included in building legislation around combustible facades.
