The first and deepest underground parking lot using secant piling method is to open to public in June in ‪‎Hangzhou‬, east China's ‪‎Zhejiang Pprovince.

The three piles of 19 stories extend underground, and will be able to maximize parking space to accommodate 114 vehicles. It is also very efficient: it will only take 50 seconds to park a vehicle, and 85 seconds to retrieve.
