INDIA. Mumbai International Airport, a public-private partnership venture between Adani Airport Holdings and the Airports Authority of India, is undertaking a major redevelopment of Terminal 1 at Chhatrapati Shivaji Maharaj International Airport (CSMIA).
The upgraded terminal will boost capacity by +42% to serve 20 million passengers annually, aligning with the city’s rapid growth as an international aviation hub.
Mumbai International Airport aims to integrate sustainability and innovation into the new terminal design, with a focus on digitalisation across the 2 million sq ft space.
T1 redevelopment will be carried out in phases to minimise disruption to airport operations, ensuring passenger convenience and safety.
The project will begin with the demolition of the existing structure in November, followed by construction of the new terminal.
CSMIA Terminal 2 and Navi Mumbai International Airport – scheduled to open this year – will help address the resulting capacity gap.
Together, the airports will accommodate passengers and flight schedules to meet the demands of both Mumbai City and the Mumbai Metropolitan Region.
Adani Airport Holdings Director Jeet Adani said: “The team at CSMIA is working tirelessly with our stakeholders to ensure a smooth transition, with minimum disruption to daily operations or passenger experience.
“This redevelopment is not only about expanding capacity – it is about future-proofing our city’s place on the global stage. Our priority remains to deliver the exceptional service that our passengers have come to expect.”
Building the airport of tomorrow
Expected to be completed in 2028-29, the revamped CSMIA T1 will emphasise sustainability and aim to be India’s first brownfield, biophilic airport.
The Passenger Terminal Building will be overhauled to accommodate domestic operations while allowing for future integration of international services. Designed to accommodate 20 million passengers annually, the upgraded terminal will address the growing demands of India’s expanding aviation market.
The redevelopment will include several key infrastructure upgrades, such as district cooling systems, advanced electrical substations and a revamped baggage-handling system. These improvements aim to streamline airport operations, both airside and landside.
A notable addition is the Multi-Modal Transit Hub, which will connect Mumbai’s air, rail and road networks. The hub will provide direct metro access and underground bus stations, offering more convenient transport for passengers. Sustainability is a key focus in the terminal’s design. Biophilic elements such as indoor greenery, natural light and open spaces will create an uplifting environment for passengers.
The architecture, inspired by the fluidity of the ocean, will incorporate futuristic wave-like forms. ✈
