GMR Group-led Delhi International Airport (DIAL) is planning to invest Rs98bn ($1.38bn) to expand Indira Gandhi International (IGI) Airport in Delhi.

The planned Phase 3A expansion forms parts of IGI Airport’s Master Plan 2016 and seeks to boost service level requirements and enable the airport to manage the increasing number of passengers efficiently, Indian news agency PTI reported.

Upon completion of the Phase 3A expansion work, IGI Airport will be able to accommodate 100 million passengers per annum (MPPA), up from its existing capacity of 70 MPPA.

GMR Group managing director I Prabhakara Rao told PTI: “We have arranged for funds. We have already gone into international bonds.

“The airport expansion project cost is met through a combination of three components, internal cash accruals, real estate monetisation, and borrowings. This includes $350m FCB, equivalent to Rs24.25bn, raised as part of expansion funding and internal cash accruals of Rs3bn.”

As part of the expansion plan, DIAL will combine the arrival and departure terminals to form a new integrated Terminal 1 and will upgrade the apron.

Baggage handling and security screening systems will also be upgraded to meet the increased capacity requirement of Terminal 1.

The total area of Terminal 1 will increase from 64,140m² to 192,985m², while passengers’ handling capacity will increase to 40 MPPA from 20 MPPA.

Work on the project is expected to be concluded between 2020 and 2022.

Other enhancements at the airport will include the construction of a fourth runway and dual elevated eastern cross taxiways (ECT).

Landside developments and T3 modification works will also be carried out for circulation and connectivity improvements.

Upon completion of the expansion, IGI Airport will become the first airport in India to have four runways and dual elevated eastern cross taxiways (ECT).
