The total cost for these upgrades, to be completed between financial years 2016 and 2019, is pegged at Rs 1,600 crore, including interest cost and the pre-operative expense of Rs 341 crore. Executives at the Mumbai International Airport Ltd (MIAL) outlined the development plans last week and will form an Airport Users Consultative Committee comprising airlines, the Airport Authority of India and other stakeholders.
MIAL did not respond to an email query.
The airport is the second busiest in the country but suffers from airside congestion, reducing capacity. The integrated T2 terminal opened for international operations in February; domestic operations will shift there next year. Its hub potential, too, is limited. The second phase of construction at the airport is aimed at improving both the connectivity to the terminals and boosting terminal & runway capacity.
This includes expanding the T2 by building the southeast pier that will let MIAL add seven passenger boarding bridges or aerobridges, taking the total to 29 bridges.
The proposed metro link to the airport as part of the Colaba-Santacruz Electronics Export Processing Zone (-Seepz) line will reduce the commute time between Colaba and the airport to 40 minutes from around an hour now. In the airport, three stations have been planned — one each at the domestic and international terminals and in the GVK SkyCity, a commercial hub being planned on airport land.
The cost of the stations at the terminals will be included in the airport project cost, while of that at the airport colony will be part of the SkyCity. The total cost of developing the metro lines in the airport is estimated at Rs 518 crore.
Totally, the Colaba-Seepz line, being executed by the Mumbai Metropolitan Region Development Authority, will cost around Rs 23,000 crore.
A new taxiway will be built creating an additional aircraft holding area before the takeoff point of the main runway.
This will give the Air Traffic Control flexibility to change the departure sequence at the last moment, leading to greater runway capacity, MIAL said in a presentation to airlines last week.
A tunnel is being proposed to reduce the time taken for transfer between the old domestic terminals and the T2. A 600-metre tunnel with 100-metre ramps on both the sides beneath the secondary runway will be built to cut the distance between the two terminals by two kilometres and the commute by six-eight minutes.
