Ground conditions appear a major source of cost and time overruns in infrastructure projects, which recent Dutch research confirms. As an answer to these cost and time overruns, the application of well-structured and ground-related risk management has rapidly evolved in recent years. The Geo Risk Scan proves to be an effective tool for quickly providing information about the degree and the quality of geotechnical risk management in infrastructure projects. This paper describes the Geo Risk Scan, as well as its application within five projects. The evaluation of the five projects resulted in six main lessons. These lessons may help project owners, engineers, and contractors to manage their construction projects.
