Identification and Prioritization of Risk in Civil Projects Using Gray Systems Theory

Abstract
There are many concrete structures that need to be retrofitted for different reasons, such as computational errors, mistakes in construction, use change, loading etc. Risk is inherent in all projects and is not possible to eliminate it. However, it can be effectively managed to reduce the impact of risk in achieving project objectives. However, it is likely to occur at least in one aspect of the project such as time, scope, cost or quality. In these retrofit projects, if the existing risks are not identified and reviewed, they can create a lot of damage and hazards which are very difficult to compensate for these risks and injuries and even sometimes impossible. For this reason, the risks involved in the retrofitting of concrete structures should be evaluated. In present study, Expert choice software is used to identify important factors of risk assessment of concrete structures using grey analytical hierarchy process method.
