Construction Design
The construction of the office building in Charles de Gaulle Square, taking into account the foundation conditions on site, the characteristics of the designed structure and the additional requirements imposed by existing buildings in the vicinity (especially the gallery and subway station) was designed to perform construction by simultaneous execution of the underground and above-ground levels (process also known as “top-down”), in a space delimited by an enclosure of buried walls, without the unevenness of the groundwater outside. The system is secure in terms of the protection of the premises and the neighboring buildings, fast and quite advantageous from an economic point of view.
Despite the difficulties of conception and execution, generated largely by the original character for Romania (it is the first construction with 5 basements and, at the time of construction, one of the tallest civil structures in Bucharest). However, through a careful approach to the design phase and a sustained effort throughout the execution, our team managed to control in good conditions the achievement of this goal.
The office building built in Charles de Gaulle Square in Bucharest has a height of 5 basements, ground floor and 17 floors, an infrastructure depth of approx. 16.20 m (including the raft) and a height above the ground of about 68 m.
Address
Piața Charles de Gaulle Nr. 15
The resistance structure of the building is made of a strong reinforced concrete core with rigid reinforcement which is the main level of resistance against horizontal loads and metal frames in two directions, braced in facades with a K-shaped metal brace, to balance the center of torsion. The floors are made in the form of slabs (35 cm thick) of reinforced concrete in the basements, respectively main metal beams from laminated profiles, beams with secondary bars and 12 cm thick reinforced concrete slab, for superstructure.
The foundation system, designed in correlation with the construction of the excavations and the infrastructure, consists of a general screed and floating piles, arranged under the vertical elements of the resistance structure: pillars and central core.
The process of simultaneous execution of the infrastructure and a number of above-ground levels (the “top-down” process) allowed the performance of anchoring works or metal sprays, the role of supporting the enclosure in molded walls being taken over by the basement floors, which are concretes as the excavation deepens.
