BMRCL Invites Bids for Bangalore’s Gottigere – Swagath Road Section
After kickstarting the bidding process for the 18.80 km RV Road – Bommasandra line in late-2016, the Bangalore Metro Rail Corporation Ltd. has now also initiated the civil bidding process for Bangalore Metro’s new 21.25 km Gottigere – Nagawara line under the 72 km Phase 2 project. Today, they published a notice inviting infrastructure companies to bid for constructing its 7.50 km elevated viaduct in south Bangalore from Gottigere to Swagath Road Cross which includes 5 new stations.
This section of the line will be built on Bannerghata Road and is officially referred as Reach 6-CC-01. Further north, the line is going to consist of a 13.79 km underground section from Dairy Circle to Nagawara, and is likely to consist of 3 packages 4 packages (as per the MD) for which bids are expected to be invited this year.
On behalf of Managing Director, BMRCL, General Manager (Contracts) invites Tenders for the work of “Construction of Elevated Structure (viaduct and stations) of length 7.50 Km (approx.) from Gottigere to Swagath Road Cross (Chainage 00.00 m to 7501.818m) including Kothnur Depot, entry line, road widening and allied works and 5 numbers of Metro Stations viz. Gottigere, Hulimavu, IIMB, JP Nagar 4th Phase, Swagath Road Cross in Reach 6 line of Bangalore Metro Rail Project, Phase-2″

Besides constructing the viaduct in 27 months, the contractor will also be responsible for constructing 5 new stations at Gottigere, Hulimavu, IIM-Bangalore, JP Nagar 4th Phase and Swagath Road Cross. The multi-level Jayadeva Interchange Station on this line will be constructed under a separate package for which the BMRCL invited bids in December 2016.
As I’ve mentioned before, the entire line and other system contracts are going to be funded through loans obtained from the European Investment Bank (EIB) and Asian Infrastructure Investment Bank with whom the BMRCL has been in talks with since mid-2016. BMRCL’s notice confirms that:

Tender documents for this package will go on sale on March 8, 2017 and the BMRCL has estimated it to cost Rs. 575.52 crores. The last date for submitting bidding documents is 3 pm on May 18, 2017 after which the bids will be opened & evaluated for eligibility at 3:30 pm. Financial bids are expected to be opened in Q4 2017 with ground work starting in Q1 2018. This line’s depot will be built at Kothanur and as such, starting operations will not be dependent on the underground section. Timing wise, since this line will be a part of the multi-storey Jayadeva Interchange, I expect it open no sooner than 2022.
Phase 2’s Status
With this development, the BMRCL has completed inviting bids for all elevated sections of Phase 2 (see list). Now only the 13.79 km underground section (in grey) is pending.

Hi TMRG
I feel BMRCL should explore all other options rather than going with this underground route.
Elevated track will be very easy to built. I am sure that TBM will take lot of time as it will be same hard granite which is impossible to drill.In a way it is like repeating the same mistake without learning.
I am surprised that media or people are not saying any thing about it.
This route is very critical as it will connect Nagawara which in turn will connect to new Airport.
Hope they are increasing the number of TBM this time with smaller sections for each.
1) The city’s congested enough. Can you imagine the kind of road widening/works needed around Brigade Road alone? Not to mention it’ll feel so much more crowded.
2) I can’t imagine how many more trees they’d have to cut. They’re already dong away with 3000 or so now. If they went elevated I’m sure it’d be no different than the steel flyover that way (funnily enough, no one ever complained about the Metro cutting WAY more trees than the flyover, but that’s another thing).
2) BMRCL said they limited the station size because the costs for land acquisition beyond Dairy Circle (where the line goes underground) were prohibitively expensive. They’d probably be larger if they went elevated.
3) The Nagawara route wasn’t decided yet was it? I don’t know why people keep saying this.They even said at some point that the Yelahanka route was close to the highway and land was cheaper.
Hard rock or not, it’ll take a loooong time before this line’s ready. That was going to be the case even if they went elevated. It’s not ideal, but I wouldn’t mind waiting if it meant less concrete everywhere you look.
Extremely good analysis, Sir.
For building the elevated viaduct on Bannerghatta Road, even though the road is wider than the ones encountered after Diary Circle, road widening and allied works along with land acquisition had to be done.
Imagine doing the same thing for areas like Shivajinagar, Shoolay Circle, Mico Adugodi etc. The project cost would have sky rocketed and would have made it almost not feasible to execute. Not to mention the number of trees that would have to be removed, specially around in and around Anepalya junction.
Yes,I agree .We are talking about very hard granite.Tunneling below a living city has its own challenges.The only solution will be to
1. increase the number of TBM. Say one TBM for every two Kilometers.
That should speedup the tunneling process.
2. increase the sample drills for a more detailed understanding of soil
3.look for any new technology
4. steps to minimize the damage to water table
Let us hope TBM cutter heads dont crack this time.
you stupid imagine mg road you idiot how will they have 2 tracks like crosshairs man use your brains

Arun & ABC – thanks for stepping in! I don’t want this to turn into a toxic community and your comments are appreciated 🙂
Hi TMRG,
Few days ago Mahametro invited bids for Pune Metro where they have given companies only one month time to submit their bids. However in case of BMRCL they are giving almost 3 months time for all sections. Any particular reason why they give so much time. How much time is usually given for bids in other cities like Delhi metro, Lucknow metro, etc.
Hi, bid preparation-submission duration depends on the scope’s complexity and anywhere around 2-3 months is standard. Since interested bidders almost always demand for more preparation time, operators pad on some extra time instead of extending the submission deadline.
Check out Lucknow’s Tender page – they’ve done a good job in posting all sort of notices (inviting tenders, opening financial bids, award of contract) and replies to interested bidders.
I don’t see the tender info on the official website.
Hi, it got posted on the 9th – I’ve added a link to it above. My post was based on their newspaper advertisement.
Have you left posting monthly report of delhi metro phase’s 3.
Pls. do update about Janakpuri-kalindikunj section in detail bro asap.
Hi, Phase 3’s tunneling works are complete, so I don’t see a reason for posting again. 2 TBMs are currently waiting to come out at the Gurdwara Shaft (between Majlis Park – Azadpur) and I’ll share an update whenever they do.
Hi TMRG,
Can you privide DPR of this line?
Hi, it’s not available online and the BMRCL has shown no interest in publishing it either. At the most, we’ll get to see the line’s alignment with station locations.

As per news paper they now plan to use 8TBM machines for 13.75 km and target is 27 months.
So average distance per TBM machine is (13.75 x 2)/8 = 3.43 km each.
@TMRG – Is my calculations correct ?
I calculated further.
This comes to 4.2 meters( approx ) per day per TBM. This is based on assumption that TBM will be working every day 7 days a week.
@TMRG – Do you think this is achievable.
I remember that in hard Granite soil , TBM was drilling only 1 to 2 meters a day. But in loose soil / soft soil TBM progressed 6 to 7 meters a day.
The main delay was that cutter head broke and TBM had to wait for 6 months to get new cutter head from Italy.
Hi, the exact length of the UG section is unknown right now, but let’s assume it’s 13.75 or 13.79 km as it’s been reported in this past. This number consists of many sub-parts and not everything is built by TBMs. Components: station box (250m each), TBM tunnels, possibly NATM tunnels, cut and cover section and ramps to exit/enter the tunnels. From my observation around the country, only 1/2 to 3/5 of the UG section is ever built by TBMs.
I know the media has published 8 TBMs, but let’s see what the BMRCL says in their tender documents on the number & type (new, refurbished/old). Once those TBMs are ready to be delivered (see this example from Lucknow), we’ll get to know more the tunneling plan and proposed length of tunneling drives by each TBM.
As usual BMRCL once again proved their incompetence. UG section was the last to be awarded in phase 1 and same in phase 2 no lessons learnt. I am sure BMRCL will make same mistakes related power and other track related issues in phase 1 and not open up partially completed sections .
I wonder apart from govt how will agencies fund BMRCL with such high level of incompetence
I wonder if they have really planned this line in detail. Right near Jayadev, there are a couple of big religious structures, where road widening is impossible. Further on near the Mico factory the road is very narrow due to more religious structures. Even though the line goes underground here it would be impossible to construct a station using cut-and-cover technique. Same for Tannery road, Pottery road etc. These are “sensitive” areas.
I have no real hope for this line till 2025. Till then it will be set of half finished structures.
Does anybody know where exactly would be the Gottigere metro Station?
Hi, unlike the BYP-Whitefield extension or RV-Bommasandra line, the BMRCL hasn’t revealed the line’s alignment+station locations. From my understanding, it’s supposed to be very close to Mount St Joseph school.
Mount St Joseph school.is not in Gottigere…. Its close to 2km from Gottigere.. Does Metro does not reach Gottigere area??
Hi TMRG, can you provide any detail on the above question ?
Mount St. Joseph School is 1.5 km away (Kalena agrahara) from Gottigere, can someone please find out exact location of Gottigere Station? Looks like last station is going to be Kalena agrahara from where the line turns towards Kothnur depot. So, this should be called as either Kalena agrahara-Nagawara line or Kotnur-Nagawara line. Very sad if this becomes reality. Gottigere deserves a Metro station!
Is it even possible ? o_o

Lot of news today in newspapers today

ANY LATEST UPDATE ABOUT DELHI
Hi, I’ll share some images of Kashmere Gate soon.
Inspection of work at majestic metro station Bengaluru
https://www.youtube.com/watch?v=xZmGc6rbbbI
Have they selected the contractor for RV Road to Bommasandra line ?
Evaluation of eligibility is underway. That will be followed by the opening and evaluation of technical bids. Financial bids (last stage) are expected to be opened in Q3 (June – Sept) to reveal the winner/selected contractor.
The tender for UG section property demolition has been floated. What are your predictions regarding the civil tender?
Hi, it should be out as soon as EIB/AIIB approve the tender documents. I’d say max another 3 months.
But in this link they are going to issue tender for UG in the next month? http://bangaloremirror.indiatimes.com/bangalore/cover-story/dairy-circle-to-nagawara-metro-link-announced-but-it-wont-be-quick/articleshow/57504077.cms
I’d be a little cautious with what the MD says, but yes, the notice should be out anywhere from now to the next 3 months. Anything more than that would be ridiculous as the project is running way behind schedule.
Wondering where the UG station in MG Road will be located …Any ideas ?
Not revealed, but most likely below Kamaraj Road or below the eastern edge of Manekshaw Parade Grounds
Gottigere station which is being proposed is almost one and half Km from Gottigere. Its actually Kalena Agrahara and not Gottigere. Misleading information provided by BMRCL. Guess its vote bank politics.
Hello TMRG,
Just curious….If elevated section Metro line work from gottigere to swagath circle is completed,Will it be commisioned partly and made operational? or does it have to wait till the UG section [ swagath to nagawara ] work is completed?
Hi, since the depot is at Kothanur, BMRCL will not have to wait for the underground section to be completed. That’s one good thing about all new elevated sections in Phase 2.
Given the tendering delays in the underground section and how elevated sections are easier to construct, the Gottigere – Swagath Road Cross section will definitely open up first.
Hi, Can you tell me the first station location (starting from Gottigere) of Gottigere metro? Will it come near to Nice road junction?
