Mumbai Metro line 3 to cost ~7,000 crore more

The line 3 of Mumbai Metro is expected to cost ~30,000 crore. The earlier estimate, based on a detailed project report (DPR) from 2011, was ~23,136 crore.

“There is a gap between the approved cost and the actual completion cost. There is a provision to allow for revised costs, and we have already initiated that process. The gap is for the value of time loss and some changes that occur while implementing the project on ground,” said Ashwini Bhide, managing director, Mumbai Metro Rail Corporation (MMRC).

At 33.5 km, the line 3 is the longest corridor of the planned Mumbai metro network. The fully underground stretch runs along Colaba-Bandra-SEEPZ. The MMRC is the nodal agency for constructing this line.

The project is being financed through a mix of debt from Japan International Cooperation Agency (Jica), equal equity contribution from the central and state governments, and an additional subordinate debt.

Bhide said the project was on time to be completed by 2021 as planned, but if a proposed depot at the Aarey Colony was delayed, there could be a problem.

The metro project has faced protests over this depot in the western suburb of Mumbai. Green activists claim the construction of the depot will destroy green cover in the area.

Bhide said the allegation was baseless and the disputed stretch had been classified as grazing land. The MMRC now awaits clearance from the Tree Authority to cut some trees and construct the Metro depot.

“It is crucial because our operations start from there. By the end of 2020, the first train will arrive, for which depot needs to be ready,” Bhide said. She added, “Earlier we had a cushion (for delay in clearance), which is now wiped out completely.”

Bhide expects 80 per cent of the Metro line’s tunnelling work to be completed by December this year. “Some additional tunnelling will be completed by March–April next year. Station works are at different stages (of completion) and progressing well,” she said.
