Mumbai Airport will start tearing down the north section of Terminal 1B in January 2027, the first phase of a Terminal 1 redevelopment that Adani Airport Holdings says it can no longer defer on safety grounds. For demolition contractors and the crane, piling and concrete fleets that follow them, this is a dated start on one of the busiest airport sites in the country. Nobody has said yet who will do the work or what it will cost.
The quick facts
- Phase 1 demolishes the north section of Terminal 1B, about one-third of Terminal 1’s capacity, from January 2027.
- Terminal 1 handles about 15 million passengers a year now and is planned for up to 20 million after redevelopment, a 33% rise.
- Around 5 million passengers a year, roughly 9% of the airport’s 55 million, will be temporarily shifted off the terminal. Airlines can move to Navi Mumbai International Airport if they choose.
- Project cost, completion date and contractor have not been disclosed.
What did Adani Airports announce?
Adani Airport Holdings, which runs Mumbai International Airport, said the nearly 60-year-old Terminal 1 has been a known safety concern for years, held together by temporary fixes. A fire at the terminal in April 2026 made the risk harder to live with. Business Today reported the plan on 3 October, and Swarajya, NBM&CW and International Airport Review carried the same capacity and timing figures. CEO Arun Bansal said Navi Mumbai’s availability is what allows a phased rebuild instead of shutting the whole terminal.
What it means for buyers
The first job is demolition, and the setting decides the kit. A multi-storey concrete terminal coming down beside a live terminal and an active apron is not a job for explosives. Expect controlled mechanical demolition: high-reach excavators with shears and pulverisers working top-down, mid-size machines carrying hydraulic rock breakers for slabs and foundations, and wheel loaders and tippers clearing debris on tight, scheduled haul routes. Dust and debris control near aircraft will set the pace more than machine output.
A January start also matters for the calendar. Mumbai’s monsoon usually shuts down heavy site work from June, so the contractor gets roughly five dry months to bring the structure down and clear the footprint before the rains.
The build that follows is a concrete job. Foundations, frames and a new terminal block pull piling rigs, batching plant, transit mixers and concrete pumps. Crane choice is the awkward part: height limits around a runway constrain boom and jib heights, so the lifting plan will likely lean on mobile and crawler cranes and restricted-height tower cranes rather than the tallest units available.
Our take: the demolition window is short and specialised, so high-reach rigs will probably come from specialist demolition firms or hire fleets rather than new purchases. The concrete train is the longer, steadier demand, and it runs for the full build. With the start date three months away, the demolition and main civil awards should surface soon.

What to watch
- The demolition and main civil contract awards, and whether one EPC firm takes both.
- A disclosed project cost and completion date for the Terminal 1 rebuild.
- Which airlines move flights to Navi Mumbai, which signals how much of T1B goes dark at once.
Bidding for demolition or civil packages? Line up breakers, excavators and cranes early. Compare machines side by side and check specs before the awards land.
