Integrating Risk Assessment in Planning for Sustainable Infrastructure Projects

Using risk assessment in planning for infrastructure project has significant impact on project life cycle performance, especially construction phase, which contributes to the 80% of project's total cost. Procurement of large infrastructure projects involves large amount of time and money spent to validate the appropriate risk assessment tools and techniques for successful project schedule and cost performance. This paper discuses and analyzes how qualitative and quantitative data, in highway construction projects, has been used in construction risk assessment and required action steps that should be considered for sustainable construction engineering and management practices. Further it also identifies the impact of transportation professional perception on the probability of project's cost growth and/or schedule growth in highway projects. Cost growth statistical dependency correlations have been tested against program and project related quantitative and qualitative data.
