DSO schedule Tata's got some very experienced engineers but they are moving very deliberately, to put it nicely. Camp erection was started in August 2011, and the construction camp was completed just early this month (and celebrated with a first meal in the facilities).

The presentation from September lays out the timeline of expected completion dates of various parts of the project: steel dome on December 13th; foundations on February 22nd; structural steel for the plant on May 3rd; mechanical/electrical by August 15th. Pilot production expected in Q4 2012. Full production by January 2013.

When they start press releasing the beginning of work on the dome and the foundations then you'll see how far behind schedule the DSO project actually is.
