Structural engineers from IIT Delhi, engaged by the Civil Aviation Ministry, are expected to complete an independent assessment of the roof collapse incident at Delhi airport's T1 in a month's time, according to a senior official.
After a thorough assessment of the findings and taking into consideration other aspects, the decision will be taken on restarting operations at the terminal.
All flights from T1 have been shifted to Terminal 2 (T2) and Terminal 3 (T3), and all of them were being operated, the senior government official said.
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 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 ministry is engaging structural engineers from IIT Delhi to do an independent assessment of roof collapse incident at T1 and they are expected to complete the assessment in one month.
After the findings come in, a decision will be taken about recommencing operations at T1, the official added.
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.
T1 was used for domestic flight operations by IndiGo and SpiceJet.
From T1, the official said 72 flights of IndiGo have been shifted to T2 and T3, and 17 flights to T3, adding that all the flights are operational.
Civil Aviation Minister K Rammohan Naidu held a meeting with senior officials from regulators, airport operator DIAL and airlines to review the measures in place to ensure smooth functioning and deployment of additional manpower to manage the increased passenger movements at T2 and T3.
Naidu visited the Airport Operations Control Centre (AOCC) on Sunday to review the operations as T2 and T3 are now also handling the traffic of T1.
As per an update provided by the ministry on Monday, the war rooms to help passengers have been activated and close coordination between DIAL and airlines is being facilitated.
Two sources in the know said it might take a few months before operations can resume at T1.
In response to a set of detailed queries related to T1, DIAL on Sunday said its cross-functional teams are actively evaluating the situation and engaging with various stakeholders to ensure passenger safety and convenience.
"We remain committed to maintaining flight operations at T3 and T2, while operations at T1 are temporarily suspended. We appreciate the understanding and support of all stakeholders," a DIAL spokesperson said in a statement on Sunday.
To queries about business loss of concessionaries operating shops and services at T1, the spokesperson had said as the evaluation process is still ongoing, it is too early to provide specific inputs.
