Construction companies undertaking major reconstruction projects are often operating in dangerous locations - take Iraq as an example. As tendering starts for schemes such as the $3bn (£1.8bn) Baghdad Metro it is likely that all the major construction firms will be gearing up their recruiting divisions.

The complete Baghdad masterplan involves rebuilding the old city and a $10bn (£6.1bn) extension to the south which will house 2 million people. Additional projects in and around Karbala are thought to be worth a further $20bn (£12bn).

For companies seeking to win tenders in countires such as Iraq the cost of adding personal DNA profiling to their standard operating procedures would not amount to a significant increase in their operating costs.
