Larsen & Toubro (L&T) was awarded the contract to construct the new Terminal 2, better known as T2, in order to differentiate it from the older Terminal 2 building.
Skidmore, Owings & Merrill (SOM) was the architectural designer of the project.
SOM also provided the schematic design of structure and MEP and the detailed structural design of the roof.
Detailed design of the foundations and the rest of the structure and civil works, the MEP, IT and airport systems, including the full construction documentation of the project was carried out by L&T's in-house design team, EDRC (Engineering Design and Research Center).
The terminal covers a land area of 210,000 square metres and has replaced the previous International Terminal (which has already been demolished).
The entire project was estimated to cost ₹98 billion (US$1.4 billion) and employ over 12,000 workers.

The X-shaped terminal has a total floor area of 450,000 square metres across four floors and handles both domestic and international passengers.
It includes new taxiways and apron areas for aircraft parking designed to cater to 40 million passengers annually.
The structure has boarding gates on two piers extending southwards from a central processing building featuring a 42-metre high roof employing over 20,000 metric tonnes of fabricated steel covering 30 acres.
However, the eastern pier of T2 remains truncated due to non-clearance of slums in the adjoining plot, giving an asymmetrical look when seen from above.
The new T2 building operates Multiple Aircraft Ramp System (MARS) stands and swing gates, so that a single stand can accommodate either one wide body aircraft or two narrow body aircraft, in either domestic or international configuration.
The new terminal is connected by the six-lane Sahar Elevated Access Road to the Western Express Highway.
A metro rail link to the terminal is under construction.

The new terminal has around 21,000 square meters of retail space, lounges and travel services, over 5,000 square meters of landscaping and a multi level car park for 5,000 cars.
The parking Management System and Revenue control system for the entire MLCP has been designed and supplied by SKIDATA.
It has 192 check-in counters and 60 immigration counters for departing passengers, and 14 baggage carousels and 76 immigration counters for arriving passengers.
To transfer passengers across its four levels, the building has 48 escalators and 75 elevators.
The terminal also features 42 travelators.

In the initial phase of development, the apron adjoining T2 provides a total of 48 stands including 3 Code F stands (for the A380).
In the final phase of development a total of 38 Code E/F contact stands, 14 Code E/F remote stands and 20 Code C remote stands are provided (total 72 stands).

The GVK Lounge, the first common luxury lounge at an airport in India, opened in November 2014.
The lounge is open to First class and Business class travellers and can accommodate 440 guests at a time.
It is spread over 30,000 square feet across two levels of the terminal and has a library, a business centre and fine-dining options, apart from the usual facilities like concierge services, smoking zone, food and beverage, bar, luxury spa, shower area and a relaxation area.
The luxury lounge has won the 'World's Leading Airport Lounge – First Class 2015' award at the World Travel Awards 2015 held in Morocco.

The terminal also houses the Niranta Airport Transit Hotel and the 32-room hotel is the first of its kind in the country.
It is located on Level 1 of the terminal and rooms may be booked by passengers who have checked into the airport.
IWG plc, operating under the brand Regus operates a shared workspace out of the terminal.

The old international terminal was closed permanently at 13:00 on 12 February 2014, and international operations from the new terminal commenced from the same day.
The first arrival was Air India flight 343 (an Airbus A330-200) from Singapore via Chennai, and the first departure was Jet Airways flight 118 (a Boeing 777-300ER) to London.
