The project includes the upgrade of runways taxiways and maintenance facilities, the construction of new parking facilities and upgrades to existing systems including reception, security check and baggage handling.
The aim of the wider project is to expand the airport's capacity to 3.98 million passengers by 2032.
Funding for the project was secured in April 2017.
The deal follows the opening of the first phase of the airport's Terminal C in February 2017.
