The Brasov-Ghimbav International Airport and its subsequent Passenger Terminal is located north of Ghimbav, in Brasov County. The General Contractor of the project is the association Bog’Art-Uti Grup- Uti FM, the general designer is the company Uti Grup SA, the architectural designers are Bog’Art SRL together with DS Birou Arhitectură SRL, and the MEP designers are Uti Grup SA and UTI FM. The beneficiary of the project is the Brașov County Council. Within this project, Popp & Asociații provided structural design services, technical assistance during execution, as well as the drafting of the geotechnical study and the hydrogeological study.
The passenger terminal at Brașov-Ghimbav International Airport consists of a main structure with mixed function with overall dimensions in plan of 112.25×47.60m and a secondary structure (international departures body) with smaller dimensions in plan, 42.00×8, 80m. The height regime is B+GF+1F for the main body, with level heights of 3.53m in the basement, 5.95m on the ground floor and a minimum floor height of 3.85m. The secondary structure has a height regime of GF+1F, with 5.95m on the ground floor and 5.55m on the first floor. The connection between the two structures is made by means of two walkways at a height of + 5.95 m.
The principle of the structural system does not differ much between the two structures. For the main structure, the chosen structural system consists of perimeter frames made of reinforced concrete with metal braces for taking over the seismic forces, post-tensioned thick slab type plate and metal roof. The seismic forces are taken over by means of vertical “V-inverted” and “X” type braces in the longitudinal direction, and “X” braces in the transverse direction. They are framed in frames made of 60×80 cm rigid reinforced concrete pillars and metal beams. Reinforced concrete frames are made of 60×80 cm columns with 40×80 cm and 40×100 cm beams. The post-tensioned slab solution was considered to be the optimal solution for respecting the architectural theme that involves very large openings (between 9 and 14 meters) combined with very high payloads due to the function of the building. For the slab above the ground floor, a general thickness of 25 cm was adopted, with local thickenings of up to 40 cm.

The metal roof consists of IPE600 main beams, IPE400 panels and a horizontal bracing system consisting of rectangular pipes. An apparent cantilever of approximately 12.00 m is placed on the façade area, the top of which rests on a series of arches that transmit the load to a system of isolated foundations.
The secondary structure has a structural system consisting of reinforced concrete frames made of 60×60 cm columns and 40×80 cm beams, with a 15 cm reinforced concrete slab. The seismic forces are taken over by the reinforced concrete frames in the longitudinal direction, and in the transverse direction by a system of “X” bracing arranged on the end frames which are formed by 60×60 cm rigid reinforced concrete pillars and metal beams.
The infrastructure consists of the horizontal and vertical resistance structure of the basement and the foundation system. In the area of the main structure, the structural frame of the infrastructure consists of the floor above the basement made of post-tensioned slab solution with thicknesses between 25 ÷ 30 cm resting on contour walls of 30 cm and reinforced concrete columns of 60×80 cm. For the areas with very large openings (14.40 m), additional rows of reinforced concrete pillars of 60×60 cm have been introduced, which develop only on the height of the basement. The building will be founded directly by a general eraser. The reinforced concrete screed will be made at a height of -4.28 m compared to the height of ± 0.00 and will have a thickness of 60 cm. Considering the location of the construction on the ground, as well as the foundation depth, the excavation will be carried out in the excavated solution sloping on all sides, with a slope of 2: 3. Locally, for the elevator basement areas, and in the area of the ALA escape tunnel and areas adjacent to the control point building, a vertical excavation supported by metal sheet piles will be made.
