Evaluation criteria

All identified risks are rated on the basis of the probability of the risk taking place, impact in terms of additional project cost, project delay and the impact on the reputation of the project.

Based on a £100m project, the following risk calibration criteria are used in assessing each risk:

Moderate but limited public embarrassment, moderate news profile

Low

£500k to £2m
