The up-down construction method involves the construction of above-grade levels prior to (or in tandem with) the construction of below-grade levels within the same footprint.
Top/down or up/down construction methods are another method for constructing deep excavations in this case the basement floors are constructed as the excavation progresses the top/down method has been used for deep excavation projects where tieback installation was not feasible and soil movements had to be minimized. Basement study report dated march 2013 and other projects where the relevant information was available some of the projects are confidential 3approach this study is based on detailed drawings (plans and sections) and the pre construction stage programmes from 12 case studies. Structural members required for top-down construction (top down construction- part 2) design and construction principles for top-down method primarily call for two major structural elements case study a) the top-down construction in indonesia.

Proceedings of the 18th international conference on soil mechanics and geotechnical engineering, paris 2013 1 top down construction alongside of bosphorus – a case study construction en « top - down » le long du bosphore - une étude de cas. But top down construction needs very efficient planning and designing and skilled supervision and labour force top down construction is the need of the hour as it is highly time efficient and is becoming popular and is coming more and more in practice with every passing day. The benefits of up-down construction, the sequence employed by this project, and the innovative structural and foundation design and construction methods devised to facilitate its.
Although the conventional top-down construction method is widely used in deep excavation, it has the drawback of low efficiency attributable to the long hauling distance and the possibility of the occurrence of excessive excavation deformation and construction risk this paper introduces a case of.
Therefore, the bottom slab of the underpass works as the conventional top slab of deep excavation in this project, and the middle slab is used as the supporting structure during the top-down construction the thicknesses of the top, middle, and bottom slabs are 1,000 mm, 500 mm, and 1,200 mm, respectively. Emerging trend in deep basement construction: top-down technique s s basarkar1, two case summaries of top-down construction, where the principle authors’ firm were involved, have been emerging trend in deep basement construction: top-down technique.

Top-down construction method as the name implies, is a construction method which builds the permanent structure members of the basement along with the excavation from the top to the bottom top-down method is mainly used for two types of urban structures, namely tall buildings with deep basements.
The top-down construction method is one of the recently developed methods to control deformation attributable to deep excavation and to protect the surrounding buildings and facilities the top-down construction method, as the name states, excavates and constructs an underground structure from top to bottom. Although the conventional top-down construction method is widely used in deep excavation, it has the drawback of low efficiency attributable to the long hauling distance and the possibility of the occurrence of excessive excavation deformation and construction risk.
