Nice work Vinod..however ground realities makes it hard to accept the graph..

Its too linear for comfort!

They have fired a consultant.. they say..On site we  can still see Navayuga ppl around! Moreover when one fires a consultant there is a trough expected in the progress!

CMH road is in a mess..with hardly anyworkers doing anything..

Ulsoor station work is also goin pain stakingly slow..please take a BMTC bus going towards majestic/market from OMR through ulsoor and you will see the 'progress'!

However I will try to pitch in with some regular photo updates..

Vinod, with your commitment on updating this site with Metro progress, We will bring back the old Metro tracking pages (remember, we had these for BIAL, BTRAC etc).

If more people can join Vinod here - we can collaborate for some nice community tracking of Bangalore Metro project. What you would have to do is very very simple.

• Visit BMRC website regularly
• Watch out for BMRC tenders in newspapers
• Take pictures once in a while if yo pass through Metro areas
• And, yes, do read the newspapers

And then, write Metro posts on praja 1-2 times a month, just make sure you use the right tags on the posts ("BMRC", "Namma Metro").

We will restore the Metro tracking page in a couple of days.

Vinod,

Thanks for putting this up.

Need to clarify terminology and the data itself for non civil engineers on this forum. 

a. Piles - these are the foundations for the pillars

b. Pile caps - the concrete mat that rests on  the piles.  It looks like one pile cap for about 4 to 5 piles.

c.  Piers - the vertical columns that support the load

d. Spans - the horizontal sections that rest on the piers on which the tracks are laid

e. Segments - trapezoidal sections that make up a span

Correct?

Your number are all cumulative. 

At the rate at which they are progressing - assuming all goes well

a. All piles should be done in another 2 months - 61 piles at about 40 a month

b. Pile caps in another 4-5 months - 51 at about 10-12 a month

c. Piers - 6 months - 94 at about 15 a month

d. Spans - at the July rate - about 12 months. 

Spans clearly are the bottleneck to progress.  However if stretches are complete then I assume rails can be laid without waiting for the entire 7 km to be done. 

Could you add the other parts as well if possible - rails, rolling stock, stations without which no trains can run.

Thanks again - this is good data based tracking.

thanks srivathsa  for explaining the jargons....Yes the number are all cumulative.  My hunch;observing the day to day progress, they will complete it much faster.

Some activities to be note regarding reach 1 are.

1.A part of the reach 1 contract has been offloaded to gammon india.  Gammon india will be doing segment casting and launching from trinity to CMH road i guess.

2.Another set of launching trusses hasbeen put in place near old madras station by navayuga engineering, they should start launching segments from this end very soon.

3.As regards the stations, old madras station by IVRCL has showed good progress.  Piers are already showing up.  Piling work happening for trinity station by punj loyd. Working is slow at ulsoor station, which is one of the first stations were work was started.

yes will add rails, rolling stock stations as we go along.  And BMRCL wants to lay tracks on the MG road stretch first and take up tracking laying as when stretches are complete of 1 km or more.
