The Mumbai Metropolitan Region Development Authority (MMRDA) on Sunday published two seperate notices re-inviting bids from infrastructure firms for constructing Mumbai Metro’s 32.32 km Line-4 (Wadala – Ghatkopar – Mulund – Thane – Kasarvadavali) and the 11.007 km eastern section of Line-2B (Bandra Kurla Complex – Chembur – Mandale).

This development comes three months after the first round of bidding got scrapped when the lowest bids received were 19% to 27% higher than the MMRDA’s estimates. The MMRDA then immediately clubbed Line-2B’s 12.714 km western section (DN Nagar – Bandra West – BKC) into one big package and re-invited bids for which Simplex Infrastructures emerged as the lowest bidder last week.

In the new second round, the MMRDA has not clubbed packages together, but instead increased their estimates by only 2-4% while retaining the same scope of work, so it’ll be interesting to see how the firms respond especially since their internal calculations were collectively way higher in the first round. For comparison, I’ve added the old and new estimates beneath each package’s scope below.
