Table 7: Cont. To effectively address these risks, it is essential to focus on those with the greatest impact on the bridge lifecycle. By applying the Pareto principle, which typically suggests that 20% of causes are often responsible for 80% of the effects, to the survey results, Table 8 has been organized to include all necessary data for creating a Pareto chart. This chart enables the identification of the critical 20% of risks that contribute to 80% of the impact on sustainability throughout the bridge project lifecycle.
