Mumbai Metro Line-12’s Groundbreaking Held to Start Construction

Maharashtra’s Chief Minister on Sunday formally inaugurated construction work on Mumbai Metro’s Line-12 (Orange Line) which will connect Kalyan – Dombivali – Amandoot (Taloja) via elevated 19 stations.

Mumbai’s Line-12 by Metropolitan Region Development Authority (MMRDA) will be built as a 22.17 km long southern extension of the partially under construction 23.53 km Line-5 (Thane – Bhiwandi – Kalyan) at an estimated cost of Rs 4,132 crore.

Line-12’s foundation stone was laid by Prime Minister Narendra Modi in September 2019, and SYSTRA MVA Consulting – DB Engineering & Consulting JV was appointed as its General Consultant (GC) in December 2022.

Gawar Constructions was declared the lowest bidder for Line-12’s construction contract under Package CA-240 in February 2024 after placing a bid of Rs. 2037.20 crore in the second round of tendering.

The project has a tight 30 month construction deadline, and MMRDA anticipates the line to open up by 2027-end which seems extremely ambitious to me for a metro rail project in the Mumbai MMR region.

Brief Scope: Part design and construction of elevated viaduct (chainage -860.224 m to +21316.022 m) and 19 elevated stations viz. Kalyan, APMC Kalyan, Ganesh Nagar, Pisavali Gaon, Golavli, Dombivli MIDC, Sagaon, Sonarpada, Manpada, Hedutane, Kolegaon, Nilje Gaon, Vadavli (khu), Bale, Waklan, Turbhe, Pisarve Depot, Pisarve, Amandoot, including connecting line to depot from main line reference chainage 12+543 from Vadavli (khu) to depot (chainage 0+000 to 1+393) of line 12 [Kalyan-Taloja] [excluding architectural finishing & pre-engineered steel roof structure of stations] of Mumbai Metro Rail Project of MMRDA

This was just a ceremonial groundbreaking event and the start of actual construction will take a few months due to pending pre-construction activities such as project staffing, barricading, utility shifting, geotechnical investigation etc.

When construction begins, 22.17 km long Package CA-240 for Line-12’s construction will be the longest EPC package in India’s metro construction history. The current longest is Bangalore Metro Phase 2B’s 15 km Package 3 which is under construction by NCC.
