The Navi Mumbai International Airport (NMIA) has been in the works for almost two decades, and is finally set to open its doors at the end of September. This highly anticipated project has faced numerous challenges, from environmental battles to resettlement issues, but has ultimately prevailed in becoming India’s financial capital’s second major airport.
Inception and Planning
The idea for NMIA was first conceived in the late 2000s, when it became clear that the existing Chhatrapati Shivaji Maharaj International Airport (CSMIA) was nearing its operational limits with its single, intersecting runway system. In 2007, the union cabinet gave its approval for a new greenfield airport in Navi Mumbai, with the goal of relieving congestion at CSMIA and preparing for the city’s growing passenger demand.
Challenges Faced
Between 2011 and 2017, the project faced numerous challenges in balancing urban development with ecological and social responsibility. The City and Industrial Development Corporation (CIDCO) was responsible for orchestrating one of India’s largest rehabilitation and resettlement exercises, relocating and compensating thousands of families in villages around Panvel and Ulwe. Engineers also had to redesign drainage systems and river diversions to protect wetlands and prevent flooding. Clearances from the Ministry of Environment, Forest and Climate Change and the Directorate General of Civil Aviation (DGCA) were also required, further delaying progress.
Tendering and Bidding
In 2018, CIDCO opened tenders for a private partner to take on the project. With an estimated cost of over Rs16,700 crore, NMIA is one of India’s most expensive public-private partnerships. The unresolved rehabilitation issues and the engineering challenges of flattening hills, reclaiming land, and building runways over creeks made the tender process risky but ultimately rewarding.
Land Acquisition and Operator Selection
In 2019, major land acquisition was declared complete, paving the way for private operators to confidently move in. In August 2021, Adani Airports Holding Ltd.(AAHL) took over the project, marking a significant turning point. The company is also responsible for managing CSMIA, making it the single operator for Mumbai’s “twin-airport” system. With this, construction began in earnest as hills were leveled and earth was moved to prepare for runways, taxiways, and terminal foundations.
Construction and Design
In 2022, CIDCO officially handed over 2,866 acres of core land to AAHL, giving the green light for heavy machinery to move in and begin construction. By mid-2023, construction was over 50% complete, and the global design of the terminal, inspired by India’s national flower, the lotus, was revealed. The terminal, designed by London-based Zaha Hadid Architects, promises both striking aesthetics and operational efficiency.
Countdown to Inauguration
