(i) The structures above ground can be carried out simultaneously with the structures below ground. This greatly reduces the time for construction.
(ii) By using this approach, settlement can be reduced.
(iii) Since the permanent columns and slabs can be utilized to support loadings during construction, it saves the cost of formwork.
