Construction companies from Japan and Australia have started work on a 182-meter tall skyscraper in central Sydney as part of a collaboration to build what will be the world’s tallest hybrid timber building using eco-friendly wood product.
Tokyo-based Obayashi Corp. and Sydney-based Built Pty Ltd plan to complete construction of the 39-storey ‘Atlassian Central’ in 2026, which will be used for offices, housing and retail outlets , the companies recently announced in press releases.
The companies aim to reduce carbon dioxide emissions during construction by 50% or more compared to a conventional construction project and operate the tower entirely on renewable energy, they said.
Beginning on the seventh floor, a hybrid timber structure will consist of a combination of steel frames and cross-laminated timber, or a timber panel made from glued layers of sawn timber.
The product would emit less CO2 during its production and would be lighter than concrete, while it can be recycled for other uses, according to the Japanese construction company.
Reinforced concrete will be used under the seventh floor, including the basement, the two builders said.
“Nothing about this project is typical,” Built CEO and Managing Director Brett Mason said in a company press release.
“It was designed and developed to be a proof of concept of what the future of buildings should look like that have a low environmental impact in both construction and operation.”
In Japan, Obayashi has been emphasizing in recent years the construction of wood buildings with low CO2 emissions and increasing the use of the environmentally friendly wood product.
In March, the Japanese company completed an 11-story, 44-meter high building in Yokohama near Tokyo, the tallest in the country whose main structural elements such as columns, floors and walls are all made of wood, has he declared.
Obayashi “aims to achieve a sustainable society by developing and promoting the use of recyclable resources such as wood and wooden materials,” Obayashi said, adding that he will address social challenges such as achieving neutrality. carbon.
In 2016, Obayashi and Built signed a strategic partnership to cooperate on some large-scale construction opportunities in Australia.
