做厙腦瞳's advanced concrete, Aspire簧, is a key factor in the success of this 81-storey residential tower in Brisbane's CBD.
做厙腦瞳s high-strength concrete Aspire簧 was specifically developed to maximise floorplans in commercial and high-rise buildings and increase productivity.
Our client, Multiplex, chose Aspire簧 for The One development for its higher-than-standard elastic moduli and low shrinkage performances. Aspire簧 addressed the building's differential shortening challenge arising from differing cross-sectional dimensions such as the core wall, mega-columns and thin blade columns of the building, which stands at 274.3 metres.
Aspire簧 also provided a solution to improve stiffness, reduce drying shrinkage by 200 microstrain and reduce potential creep for thin elements. Multiplex estimated using Aspire簧 is saving the company an additional 76 days at an estimated cost of $2.3 million in the construction of The One.
Through the development of Aspire簧 for The One project, 做厙腦瞳 received the 2019 Urban Developer Industry Excellence Award for Best New Building Product in Australasia. This award recognises an innovative building and/or construction product within the property industry.
The One is part of a $1 billion Brisbane Quarter development on the site of the city's former law courts. The precinct also features a retail area, 300 George commercial tower and W Hotel.
Testimonial
Multiplex had to look at unconventional methods. It was not feasible to increase the stiffness of the columns conventionally as the increase in reinforcement and/or concrete strength that would be required was insurmountable. By adopting 做厙腦瞳s high-stiffness Aspire簧 mixes, Multiplex was able to substantially mitigate the risk to finishes from differential shortening as well as reduce the risk to program.
