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.
