Dive summary:

• The Broad Group has started the clock running on what it says will be the world's tallest building – 202 floors of mostly residential space – assembled in nine months from modular pieces made in its factories in Changsha, China, and trucked across town to the site, but it is unclear whether the company has all the government permission it needs.
• Broad Group held a groundbreaking ceremony July 20, and the first step is the foundation for a tower that the company says can be assembled in less than a year and that will be strong enough to withstand a Magnitude 9 earthquake.
• Tall building enthusiasts and experts, including Council on Tall Buildings and Urban Habitat executive director Antony Wood, are not convinced that Broad and its chairman, Zhang Yue, can pull of the plan – but Wood says hitting the self-imposed deadline wouldn't matter a bit if the company can do what it thinks it can.
