Top- down construction, which allows the execution of infrastructure and superstructure of a building simultaneously, used frequently by OCTAGON



Multiple underground level buildings, located in crowded urban areas need the implementation of complex construction methods, able to guarantee their solidity. One of the most efficient solutions is the top-down construction. OCTAGON CONTRACTING & ENGINEERING has used this procedure frequently, for the construction of several office buildings.  
The main benefit of this method consists in the fact that the infrastructure and the superstructure of the building can be executed simultaneously, reducing significantly the execution term.
The construction method was adopted at the beginning of the ‘60s, but it is still used by a limited number of constructors, as this is not a procedure easy to apply: excavation under the floor is difficult to perform.
Top- down construction is performed in several stages.
OCTAGON started to use the top- down construction method to execute the infrastructure of the tallest office building in Bucharest: Sky Tower (Barbu Vacarescu Blvd). The company built three reinforced concrete floors, of 4,600 sqm each.

Between 2010- 2011, OCTAGON built the foundation and the structure of the underground levels 3 and 4 of building A, within Hermes Business Campus complex (5-7 Dimitrie Pompeiu Blvd- Bucharest).
The company used the top- down system to build the office projects Cathedral Plaza (General Berthelot), Charles de Gaulle Plaza (Charles de Gaulle Square) and the four star hotel Novotel (Calea Victoriei).
