An Australian company has been awarded the contract to clean every window on the world's tallest building Dubai's Burj Khalifa.
The company, Cox Gomyl, will use both muscle power and machines to keep the windows on the 828-metre high building clean and gleaming. The 20-storey Burj Khalifa was officially opened on Monday.
A company official, Dale Harding, told Australian Broadcasting Corporation (ABC) News that the company was taking on a massive task.
"There's around 24,000 windows in total. I think that's about 120,000 square metres of glass," he said.
The tower was previously referred to as the Burj Dubai.
It has now been named the Burj Khalifa after the ruler of the neighbouring Emirate of Abu Dhabi, whose multi-billion-dollar bailout helped Dubai's biggest developer, a state-owned company, avoid a potentially disastrous debt default in November.
