GACM, the concessionaire for Mexico City's future international airport, has invested 25bn pesos (US$1.3bn) to build the new airport since 2014.
The figure represents 14.8% of the total price of the airport, which is estimated at 169bn pesos, according data from GACM.
GACM published more than 200 contracts related to the construction of the airport, which contain information on the planning phases, the tenders, contract-awarding and implementation of the works, the group said in a release.
With the publication, GACM complied with a presidential order to make data on the contracts public, it said.
All information is available at www.datos.gob.mx/naicm, it said.
Of the 200 contracts, the tender to build the terminal building, which will require investment of 11bn pesos, and the tender to build runway No. 3 at a cost of 258mn pesos, are among those highlighted.
GACM has said it will launch more than 40 tenders for the airport this year alone.
The airport will have a footprint of around 4,430ha and will eventually handle up to 120mn passengers a year.
