How this ranking works

This is a curated catalogue, not an exhaustive list of every megaproject. Projects are ordered by their recorded US-dollar equivalent; each detail page shows the source amount and any currency conversion. Figures are not adjusted for inflation, and construction bills, estimates, and programme costs can have different scopes. Unbuilt proposals and cancelled projects are excluded.
