Top-down construction method - discription and
The Top-down method is mainly used for two types of urban structures, tall buildings with deep basements and underground structures such as car parks, underpasses and subway stations. The method has been used for deep excavation projects where tieback or anchor installation was not feasible and soil movements had to be minimized.
