The Mumbai Metropolitan Region Development Authority (MMRDA) may have to dismantle and rebuild a section of the Metro 7A elevated viaduct because its general consultant failed to account for airport height restrictions, putting over Rs 260 crore of public funds at risk, sources told the Times of India.

The error lies in the design of overhead electrical equipment needed to run the line. The consultant consortium SYSTRA-CEG-SMCIPL reportedly did not incorporate the additional clearance required by the Airports Authority of India, which ranges from 2.5 cm to 2.4 m along the 3.4 km stretch linking Dahisar to Terminal 2 of Chhatrapati Shivaji Maharaj International Airport. The project is already 71 per cent complete, with the Airport Colony station 82 per cent ready.
SYSTRA did not respond to requests for comment. MMRDA must now decide whether to rebuild the affected structure or seek damages from the consultant.
The Mumbai Metropolitan Region Development Authority (MMRDA) relies on general consultants for design coordination on metro projects. In 2023, the Bombay High Court flagged similar design coordination failures on Metro 3, attributing cost overruns to consultant lapses. Under MMRDA's standard contract terms, cost recovery from the consultant consortium is possible if negligence is proven, though such recovery typically takes years of arbitration. The Airport Authority of India (AAI) sets vertical clearance limits near airports under the Aircraft Act, 1934, any structure exceeding those limits requires revised approval, which resets timelines. The Rs 260 crore at risk represents structural work already completed that must be demolished and rebuilt. MMRDA's board will now decide whether to seek damages from SYSTRA-CEG-SMCIPL or absorb the loss from its project contingency fund.
