I cant believe we cant get this tunnelling thing off the ground. 20% or 70% take the appropriate measure and get going already. So what did they do for the entire year to come to this conclusion? They may need to go a little deeper because of the hard rock so fine it will cost more. Politicians & Babus may be plundering crores, but atleast this will come back to benefit citizens why pinch here?
This stretch is nothing, the entire city needs more tunnels everywhere for roads, trains etc. They cant keep escaping by building overhead stuff everywhere. They better pay some more money and get some experts who have been doing this for years & start tunnelling soon. Even today Citybanan in stockholm is being laid under all kinds of surfaces. We are loosing patience.
If these guys still do not have an idea of the geology of Bangalore to know how fine a sample to take and blame the agency that does the DPR alone, they deserve a big kick on their behinds. Are you telling me that we have no idea of the detailed geology of Bangalore? Doesn't the contracting agency (BMRCL) have the responsibility of doing due dilligence to question the assumptions made in a DPR?
2012 Completion was always in doubt

I had earlier mentioned (here) that unknown difficulties might be encountered - this is just the beginning. Once they get contractors to do the job, & the job commences in earnest, more such problems will arise (such as - "water table is high here" or "soil is very loose there", etc.) - which is why tunnelling should have been accorded top priority, having known fully well that experience was lacking & the job is fraught with uncertainties & risks.
BTW, I heard that the contractor for one U/G section has already been finalized - anyone knows anything about this ?

Bad news on Namma Metro.See the Link
I think just like Reach 1, all the reaches till the underground section should be completed quickly and operated. It will improve faster movement within one zone atleast like Market to Puttenahalli on Southern Reach, Vijanagar to Leprosy Hospital, Peenya to Swastik.
It is a clear poor project management, underground work being the most toughest one and the important junction being taken up at the end of the project.
