Project Description

In December 2017 the new domestic terminal of Bogotá’s El Dorado International Airport was inaugurated. This new extension is part of the airport’s US$ 770 million modernization program started in 2007. Since then, the airport built in the early 1950s has enlarged the passenger terminal building area from 53,000 to 237,000 m2. The project includes a runway extension and the modernization of other facilities at the terminal.

The concessionaire Odinsa appointed Pedelta to develop the structural design of the new domestic flight terminal and to assist the contractor during the construction. The two-level terminal comprises a total surface area of 47,900 m2 and six jet bridges. It includes over 8,000 m2 of post-tensioned concrete slabs as well as steel roof frames. A 500 m long post-tensioned concrete slab viaduct was also built to access the new building. Key structural considerations included budget, schedule, and a high level of design quality for the exposed structure.

Design/Construction Approach

The designed structural system consists of moment-resisting concrete frames with moderate energy dissipation capability. To reduce the number of spans, a 25 cm thick post-tensioned concrete slab was designed. T-beams with variable width from 1.00 to 1.25 m were also post-tensioned with additional reinforcement to meet the requirements for seismic design. The columns are in reinforced concrete. The structural design includes long-span steel trusses supporting the roof.

This design approach is very efficient as it allows an excellent relationship between the small dimensions of the structural elements and the large spans achieved. The result is a remarkable and functional world-class terminal.
