An Interim Report has now been published by the recently formed Victorian Cladding Taskforce.
The taskforce follows the serious Lacrosse Building fire in Melbourne Docklands (November 2014) and later the Grenfell Tower disaster (71 fatalities, June 2017) in London (see Grenfell_Tower_fire ) involving the use of highly combustible cladding panels.
The report covers the use of aluminium composite panels (ACP) with a polyethylene core and expanded polystyrene (EPS) cladding, for class 2, 3, or 9 buildings of two or more storeys, and class 5, 6, 7 or 8 buildings of three or more storeys.

Prepared by the Tensile Membrane Structures Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE
Standard ASCE/SEI 55-16 provides minimum criteria for the analysis, design, and performance of membrane-covered cable and rigid member structures, collectively known as tensile membrane structures. It is applicable to both permanent and temporary structures.
Within CEN/TC 250/WG 5, CEN/TC 248/WG 4, the TensiNet Association and COST Action TU1303, an international team of researchers, engineers, architects, material producers and manufacturers has been working on this report, which provides background information in support of the implementation and development of a future Eurocode for the Structural Design of Tensile Membrane Structures.
Tensioned Membrane Structures have unique properties compared to the more conventional built environment. Besides their low self-weight and high flexibility these structures are known to be 'optimally' constructed, as they are only loaded in tension. It results in shapes adapted to the flow of forces and a minimum of material needed to realise the span.
Important revisions have taken place for fire detection and control in buildings across a number of Standards.
These set out the minimum requirements that should be in place during design and construction to ensure compliance.
Recent revisions include:
The use of ventilation and air conditioning in buildings - Fire and smoke control in buildings
Fire detection, warning, control and intercom systems - System design, installation and commissioning
Fire detection, warning, control and intercom systems - System design, installation and commissioning - Emergency warning and intercom systems

The Australian Building Codes Board have recently published a new standard for Temporary Structures.
The LSAA contributed to its development.
This Standard is intended for use in the design, construction and use of temporary structures. It provides criteria for structural safety (particularly determining appropriate wind actions), fire safety (including fire resistance of materials, fire safety services and equipment, and egress), access, sanitary facilities and certain ancillary provisions.
It is still open for adoption by particular State or Territory Authorities.
