The issue of cost control, as my fellow panellist noted, is an issue for countries all over the world. Bent Flyvbjerg has pointed out very clearly that megaprojects suffer from cost escalation and time escalation almost everywhere they are proposed and invested in. I agree that we need public sector transparency and constant vigilance over the scale of the project and over elements of the project that may be unnecessary or designed in a way that is inappropriate.
As an example, I would say that cost benchmarking against comparable international projects is one mechanism to ensure that a contractor is not taking the nation for a ride and not charging too much for the project as proposed.
