Brazil's national airport authority Infraero is planning infrastructure improvements worth 5.15bn reais (US$2.92bn) to prepare the country's airports for the 2014 World Cup.
The work, to take place between 2011 and 2014, entails rebuilding or expanding terminals at 13 airports, the official 2014 World Cup website reported.
To avoid falling behind schedule, Infraero intends to submit its action plan to Brazil's federal audit court TCU during the second week of September.
The court suspended funding for the airports of Guarulhos (Sao Paulo state), Vitoria (Espirito Santo) and Goiania (Goias), as it found evidence of overpricing, according to the report.
TCU will release funding for the airport projects once new contracts and master plans have been made.
