As the pre-construction tendering stage of the 72 km Phase 2 hots up with new notices inviting bids for construction, it’s a good time to visit the progress made on the 42.3 km Phase 1 project where roughly 12 kms of the Green Line is yet to open up for commercial services. To aid that, here are relevant excerpts/tidbits extracted from BMRCL’s December 2016 newsletter which includes images and data recorded up till December 1.
As always, let’s first take a look at some new snaps of the underground section, and then dive into analyzing the data for Phase 1:
Chickpet Station – “Base slab of 4490 Sqm is completed. Side wall (Base slab to Concourse slab) of 4105 cum is completed. Concourse slab of 8792 Sqm completed out of 9267 Sqm. Sidewall (Concourse to Roof) of 4495 Cum completed out of 4788 Cum. Roof Slab of 8429 Sqm completed out of 9565 Sqm. Ancillary Building of 1264 Cum is completed out of 1656 Cum.”
KR/City Market – “Side wall (Base Slab to Concourse Slab) of 5818 Cum is completed. Concourse slab of 9054 Sqm is completed out of 9179 Sqm. Sidewall (Concourse to Roof) of 4483 Cum completed out of 4629 Cum. Roof slab of 8799 Sqm is completed out of 9361 Sqm. Ancillary Building of 970 Cum is completed out of 1613 Cum”
Purple line – Reach 1 connecting Baiyyappanahalli – MG Road stations opened in October 2011 followed by Reach 2 connecting Mysore Road – Magadi Road stations in November 2015. Tunneling work on the line’s 4.8 km underground section which connects Reach 1 with Reach 2, between Magadi Road – MG Road, started in May 2011 and got completed in March 2014 by the CEC-CICI JV. Following that, trial runs began in November 2015. The line was finally inaugurated on April 29 2016 and commercial operations started the next day at 6 am. A comprehensive history of the underground section from bidding to construction to testing can be viewed here.
Green line – The 12.4 km Nagasandra – Sampige Road section opened up in stages on March 1, 2014 and May 1, 2015. The line’s pending 12 km section consists of 2 distinct sections – (1) a 4 km underground section from Sampige Road Station to National College Station with 3 stations under construction by the Coastal-TTS JV, and (2) an 8 km elevated section from the National College Station to the Yelachenahalli Station with 8 stations built by NCC, IVRCL – CR 18 JV, L&T and JMC.
The Green line’s tunnels from the North Ramp (near Sampige Road station) to the South Ramp (near National College station) were constructed by a JV of Coastal – TTS with some help from the Robbins Company and the CEC-CICI JV. The line’s final breakthrough by TBM Krishna took place at the Majestic Station on September 23, 2016. In late-November 2016, BMRCL pulled a train through the up-line tunnel and on November 30 commenced trial runs between the long completed National College Station – Yelachenahalli section.
The above images speak for themselves. The glare seen in both stations’ images are caused by open roof slabs which, besides the concourse level, still need to be patched up. It’s a similar story out at the Majestic Station’s north and south shafts where 3 TBMs arrived earlier this year. Inside the tunnels, only track-work on the south-bound section has been completed which allowed trains to be brought to Reach 4’s National College Station. On the parallel north-bound section, the newsletter reports that 320m of tracks have been laid out of 4000m. The installation of the 3rd rail traction system, signalling and telecommunication equipment will begin only after these works are completed.
The BMRCL and Karnataka Government are publicly targeting to open the Sampige Road – Yelachenahalli section in April 2017, but internally are working towards meeting another deadline. As we get closer to April, expect them to announce a new deadline which will hopefully be the last of Phase 1’s deliberately misleading deadlines. Old habits die hard though – they’ve already ludicrously started claiming they’ll open a bulk of Phase 2 by mid 2019 even though construction work on the Whitefield extension of the Purple Line, BIEC extension of the Green Line and RV Road – Bommasandra line will begin only in Q4 2017.
The BMRCL’s plan of commencing operations on Phase 1’s pending stretches is still pretty vague (will they first start operations on the elevated stretch as a face-saver or the entire line together?) and the organization’s PR department hasn’t been reliable or consistent with what other BMRCL officials have claimed. Either way, I’m still expecting commercial operations on the entire Phase 1 to commence only in Q4 2017.
What are your thoughts? Any news/data points you’d like to bring to my attention?
