Regarding collaps of Metro flyover in Delhi(In year 2009 )

As I have mentioned earlier that Engineers should adhere to the rules and regulations and specifications .Why in foreign countries the buildings ,bridges and flyover and all the structures dont collapse ? the reason is not far to seek.When the plans of civil structures are santioned ther are different departments which look all the aspects whether the structure in question is technically safe and no projects is sanctioned unless there is quality control laboratory which checks the quality of the materials used during constructions.India has the history of the best civil engineers in the world .Once former prime minister Pt Jawahar Lal Nehru had said that the engineers are pillars of our nation.But such lapses and structures giving way no doubt bring a bad name to the nation.I know so many young engineers who provide structural designs on line and send the same to all countries in the world.By every failure so many lives are lost apart from damages.So it is my apeal to the engineers that they should work for the nation like famous engineer like Engineer VISHASWARIA who was given the honour of BHARAT RATAN.
