Assessment of the delay risks in the execution stage of the road construction projects

Delay in the execution Stage is one of the essential challenges of the construction industry. The road construction projects often are faced with the delay issue due to their complexities in the execution stage. In the present study, identification of risks by structured interview technique, qualitative risk prioritization by expert opinion survey, and quantitative risk prioritization by analytical hierarchy process technique. The offered framework in the real project has been shown and its outputs are qualitative delayed risk prioritization with cause and effect (Ishikawa) charts and quantitative risk ratings with Expert choice software. According to quantitative ranking, financial and credit problems, lands’ appropriation, management problems, technical problems and natural disasters have the highest risk among the main criteria. Among the sub criteria of the risk, incomplete allocation, land price, gardens, incomplete feasibility studies, incorrect timing schedule, provincial credits, no money deposit, residential areas, commercial areas, agreement with the natural resources, agreement with the environment, flood, low initial estimate, national credits, industrial areas, unfavorable weather conditions, ground operations, asphalt problems, accident insurance have priority. Finally, Critical criteria analysis performed and solutions have been proposed to reduce or eliminate the effect of these delays in road construction projects.
