ANN approach to determine cost contingency in international construction project

Construction companies try to expand into international markets to create new job op-portunities. Since international construction environment is highly subject to several complex conditions, carrying out international projects is much riskier than conducting domestic pro-jects. In this risky business environment, contractors usually include a reasonable contin-gency amount as an allowance for potential risks in their bid prices to shield themselves from the outcomes of possible failures. In this context, determination of the right amount of con-tingency is critical. In this study, an ANN-based contingency estimation model, which can assist construction companies to estimate contingency more systematically and accurately, is presented.
