	Summary:
	In urban sites, due to parking problems, there is a need for constructing numerous number of underground flours. In the center of Belgrade, Timitrija Tucovica street, Alboni Promist has invested in the construction of residential and business. In this paper, shows how the construction of the underground part of the construction of this object using the method "top down". This method allows you to perform at a certain point of the underground facility construction begins with the performance overhead of the building envelope. A particular problem with such a construction is a temporary suspension slab reinforced concrete slab on a rigid steel cross-sectional profile of a complex, embedded in the piles. The calculations are complex structures such as to solve the problems of interaction design and soil protection.
