Cost overruns in transport infrastructure projects know no geographical limits; overruns are a global phenomenon. Nevertheless, the size of cost overruns varies with location. In the Netherlands, cost overruns appear to be smaller compared to the rest of the world. This paper tests whether Dutch projects perform significantly better in terms of cost overruns than other geographical areas. It is concluded that for road and tunnel projects, the Netherlands performs similarly to the rest of the world. For rail projects, Dutch projects perform considerably better, with projects having significantly lower percentage cost overruns in real terms (11%) compared to projects in other North West European countries (27%) and in other geographical areas (44%). Bridge projects also have considerably smaller cost overruns – 7% in the Netherlands compared with 45% in other NW European countries and 27% in other geographical areas. In explaining cost overruns, geography should therefore clearly be taken into consideration.
