Timber construction on the increase for commercial buildings
April 9, 2018
Quicker, cheaper and greener construction of commercial buildings will be enabled under proposed changes contained in the draft 2019 National Construction Code (NCC).
The change will apply to retail shops, carparks, storage warehouses, laboratories, hospitals, schools and aged care facilities, making it easier to use fire-protected timber in all buildings up to eight storeys in height.
This expands the current code coverage of timber construction for apartments, hotels and offices that was included into the NCC in 2016.
Changes were initiated by timber industry organisation Forest & Wood Products Australia, and has achieved the support of the Australian Building Codes Board’s technical committee – which includes a broad range of representative industry groups such as the fire services, architects, builders, building surveyors, building designers, engineers as well as state planning and building authorities – with extensive modelling to demonstrate timber construction systems can meet the required building and fire safety standards.
Timber construction systems permitted under the Code would include both traditional timber framing and mass timber building systems utilising glue-laminated timber, laminated veneer limber (LVL) as well as cross-laminated timber (CLT) products, used in buildings such as Library at the Dock in Melbourne and International House in Sydney.
FWPA National Manager Codes & Standards Boris Iskra said that under the proposed changes, builders and developers wanting to use timber would no longer have to undertake time consuming and expensive ‘performance solutions’ to gain building approval, as long as their designs met the deemed-to-satisfy requirements.
“At FWPA, we do everything we can to remove unnecessary restrictions on the use of timber. In 2016, we were successful with introducing similar changes for apartments, hotels and offices – and now we’re on the brink of extending that to other types of buildings,” he said.
“We’re proud to have successfully made the case to the authorities that timber can meet the required standards and would urge the timber industry and progressive builders and developers to make submissions supporting the proposed changes to the Code – it’s a great opportunity.”
Fire protection measures under the proposed changes include fire-protective grade plasterboard; fire-resisting cavity barriers; and a compliant sprinkler system; as well as hydrants, hose reels and portable fire extinguishers as required.
The Managing Director of FWPA, Ric Sinclair, said buildings made from sustainably sourced timber are greener than alternatives in several respects.
“Obviously, wood stores carbon dioxide over the life of the building, which other materials don’t. It performs well thermally, so it doesn’t require as much energy to heat and cool. It also lends itself to prefabrication and quick installation, meaning less disruption to neighbours and fewer truck movements,” he said.
