15 of the world's biggest cost overrun projects

Bent Flyvbjerg, professor of major programme management at the university of Oxford's Said Business School, says overruns in the order of 50 per cent in real terms are common for major infrastructure projects. He says this is because it is not uncommon for demand and benefit forecasts to be wrong by 20-70 per cent compared with actual development. Public passenger rail and urban projects tent to have especially big overruns.

Here is the list,

Canadian Firearms registry, initial cost forecast: CAN$ 2m cost, final cost: CAN$ 946m
36,917% cost overrun

Visegrad Hydroelectric Project, Yugoslavia, 5,142% cost overrun.
