The construction arm of Slim’s Grupo Carso and his majority-owned FCC submitted a bid of 84.8 billion Mexican pesos ($3.98 billion).
The consortium also includes Spain’s Acciona and Mexican firms ICA, Constructora Y Edificadora GIA+A (GIA), Promotora y Desarrolladora Mexicana (Prodemex), and the construction unit of Grupo Hermes.
The win was announced at an event in Mexico City as well as via the airport’s official Twitter account.
The telecoms tycoon edged out arival consortium headed by Portuguese builder Mota Engil and Mexico’s Omega, which had submitted more expensive bids.
This megaproject was designed by the son-in-law of Carlos Slim, Fernando Romero, and the British Norman Foster, winner of the Pritzker Prize, considered the Nobel of Architecture.
The terminal building is slated to serve some 68 million passengers annually by the time it opens in 2020 and make Mexico City a regional hub.
