The Indira Gandhi International Airport (IGIA), operated by a GMR Group-led consortium DIAL has three terminals — T1, T2 and T3 — and handles around 1,400 flight movements daily.

The detailed technical study of the Delhi airport’s now shut Terminal 1 (T1) is expected to be completed in a month and depending on the findings, the decision will be taken on recommencing operations at the terminal, a senior government official said on Sunday.

All flights from T1 have been shifted to Terminal 2 (T2) and Terminal 3 (T3), and all of them were being operated, the official told PTI.

On June 28, a canopy at the old departure forecourt of T1 partially collapsed amid heavy rains resulting in the death of a person and causing injuries to at least six people. Following the incident, the civil aviation ministry said structural engineers from IIT Delhi have been asked to immediately assess the partial collapse of the canopy.

The official said the technical study of T1 is expected to take about a month. After the findings come in, a decision will be taken about recommencing operations at T1, the official added.
