ESTIMATION OF CONSTRUCTION PHASE RISK IN ROADWAYS PROJECT

Risk is unavoidable in almost all road construction projects and is the biggest challenge in construction industry as it results in time overrun, cost overrun and degradation of quality of the project. The focus of this paper is to identifying the impact on construction phase in the effects of occurrences of risk in the roadways project. The questionnaire template was prepared based on a literature review and expert's opinion. The questionnaire was consisting of the Project details, various factors related to causes for execution of the project. The responses of the questionnaire survey collected from 286 projects were considered the analysis through management tools. The descriptive analysis shows the 59 factors influence in the roadways project and those factors grouped under 11 categories were disused. The result of descriptive analysis shows the effect on project execution. Later, the regression analysis was made to create a model for finding the probability of the risk in construction phase of the roadways project. The result of study shows the project scope, project construction management, and Regulation Social and legal risk are having high chance of risk in construction phases. The study concludes with appropriate suggestions and recommendations to control cost escalation in construction projects.
