The AU$180m tower is the second of three towers at developer Shayher Group’s Brisbane Quarter project.
The mixed-use development along the Brisbane River will include a hotel called W Brisbane, an 82-level residential tower with a riverside retail and dining precinct and the 42-level commercial tower awarded to Multiplex for construction. Multiplex is already building the hotel.
Construction of the AU$180m (£107m) commercial tower at 300 George Street will begin next month with the building expected to be complete by mid-2019.
The building will provide 48,342m2 of space and will will be targeting a 5-star Green Star rating.
Shayher Group director John Lin said: “Multiplex’s extensive experience across large-scale and complex projects has impressed us and they understand the importance of delivering high-quality outcomes, which is a perfect fit for the world-class 300 George Street project.
Multiplex’s regional managing director for Queensland Graham Cottam added: “Brisbane Quarter is an outstanding integrated development already having a significant impact on the Brisbane skyline and we are delighted to be a part of it, both with the W hotel component we are currently constructing and now with the commercial tower.
