El Dorado International Airport, the main and most important airport in Colombia, has a high demand of passengers. As response to that demand, the development of a project to build a new, more modern and capable El Dorado, was executed.
The assignment to define and to develop the new terminals was awarded to Consorcio Constructor Nuevo Dorado, as operator of the airport and winner of the bidding process raised by the Government of Colombia.
The project will be completed in four phases: the first one includes the expansion of the Main Hall, the second phase will house the Cargo Terminal, the third phase corresponds to Terminal 2, and the fourth will be the Domestic Terminal. Pedelta was involved in developing the structural design of the Domestic Terminal building.
The designed structural system consists of frames resistant to moment, with moderate power of dissipation capability. To reduce the number of spans, a 25 cm reinforced, post-tensioned concrete slab was designed. T-regular beams were also post-tensioned with widths varying between 1.00 m to 1.25 m. Columns are in reinforced concrete. Slabs and beams take the vertical loads (dead and live). Passive reinforcement was added to the beams to meet the requirements arising from the seismic actions.
Pedelta developed the structural design of over 26,500 square feet of post-tension concrete slabs, the terminal's steel structure optimization and also the design for the terminal's new access viaduct.
The Domestic Terminal building is built in two concrete floors with diaphanous spaces. The steel roof is using advance technology and has an innovative structural system for this type of construction developed in the country. This system is very efficient, allows an excellent relationship between small dimensions of the structural elements and the large spans achieved.
