Hello Shashi,
Apparently there has been another accident on the site. This time three cranes
trying to move the girder collapsed. Here are some dramatic videos. Clearly
there were some more injuries - one injured man is shown carried away and there
could well be others. The slipshod manner in which such heavy loads are lifted
is obvious.

Satyakam and Mac, both DMRC as well as the contractors (Gammon) are equally
responsible. For Gammon, this is not the first time. There has been an accident
in Hyderabad where a flyover fell on Gammon's watch. That and many other
accidents at the Delhi Metro sites should have been a wake up call for DMRC,
which is the regulatory authority overseeing the construction.
Regards,
Ashish
