Crown Group creates a seven storey waterfall

Australia’s tallest manmade waterfall – an eye-watering seven storeys in height – will soon begin construction in Sydney’s Waterloo after Crown Group completed testing earlier this month.

The $400-million Waterfall by Crown Group, currently under-construction in Waterloo, was launched in June.

Designed by architect SJB, Waterfall by Crown Group will comprise 331-apartments across three seven-storey buildings and a 20-storey sculptural tower overlooking tropical landscaping and a water garden.

A full-scale prototype was tested last week to select the desired weir for water to flow from.

Crown Group’s national construction director Craig Eglie says the tests gathered information on “water volumes, water trajectory and the performance of the various types of weirs”.

“Based on the result we will make some minor adjustments to the design so we can begin construction of the final waterfall,” Elgie says.

Crown Group and a team of experts tested four different types of waterfall weirs – Piano Keys Weir, Radius Weir, Wave Weir and Saw Tooth Weir – to ensure the final was both visually pleasing and passed construction tests.

Four weirs will be used in total, creating four separate waterfalls at varying heights up the building.

Wind monitors will also be installed to monitor wind speeds which may then vary the volume of water being discharged and which would allow some waterfalls to be switched off in periods of high wind.

The final waterfall will be positioned on an exterior wall of one of four buildings in the development complex.

Set to be completed in 2020, the project will include public art by Mika Utzon Popov, grandson of Sydney Opera House architect Jørn Utzon, in the form of a large-scale artwork.

An early indication of the popularity of the project, more than 2,000 people attended the unveiling of the development’s design at Royal Hall of Industries, in Sydney in May.
