With tunneling works on 33.5 km Mumbai Metro Aqua Line (Line-3)’s Phase 1 (BKC – Aarey) long completed, all action here for the last 3 years has focused on station civil work, system installation and architectural finishing works.
This post of mine focuses on signage installation works at Marol Naka and MIDC stations where Mettle Infrastructure on a subcontract from Larsen & Toubro – Shanghai Tunnel Engineering Co (L&T – STEC JV) is close to completing signage installation on Package UGC-07.
L&T – STEC JV’s 4.157 km Package UGC-07 connects CSIA Terminal 2 and Sariput Nagar Ramp via 3 stations at Marol Naka, MIDC and SEEPZ. The final tunnel breakthrough for this package was recorded by TBM D213 (Wainganga-2) way back in December 2019.
Both Marol Naka and MIDC stations are in the most advanced stage of completion out of Line 3’s 10 stations in Phase 1 connecting Aarey Colony – Bandra-Kurla Complex. Their signage contract was awarded to Mettle Infrastructure in July 2023 with an approximate value of Rs. 1.5 crore.
Signage reviews and walkthroughs were completed in August. Here are some images from both stations shot in September during installation:
Mettle Infrastructure has also won signage contracts for Package UGC-01 (Cuffe Parade – CST) from L&T – STEC JV and for Package UGC-04 (Worli – Dharavi) from CEC – ITD – TPL JV.
On UGC-01, installation works are planned to start at Vidhan Bhavan Station from the 3rd week of October. On UGC-04, work will start at Siddhivinayak Station on October 5.
MMRC hasn’t publicly announced a new deadline for commissioning Phase 1 between Aarey Colony – Bandra-Kurla Complex. Train and system testing (trial runs) officially started in August 2022 and their completion depends on the completion of the line’s operational control centre (OCC) at Aarey Depot.
MMRC in mid-September claimed 74.4% work for the depot had been completed for its civil, track and MEP system installation work (see recent images). Looking at that and other pending work, I reckon we’re at least 6 months away from seeing the line opening up for commercial operations.
