This document summarizes a study on risk analysis of infrastructure projects under public private partnerships in India. The study identified the main risks through a literature review and conducting interviews. A questionnaire was developed and distributed to project managers and experts. The responses were analyzed using statistical software to identify critical risk factors and their impact. A fuzzy logic model was developed and validated to quantify the risks. The model found that land acquisition had the highest mean impact. Construction risks posed the greatest overall risk. The study aims to provide guidance to concessionaires and authorities on managing risks in public private partnership infrastructure projects.
