Abstract
Implementation and management of all projects are always accompanied by ambiguities and the unknown that could have positive or negative effects on the results. Therefore, the assessment of project risks is of particular importance. In this study, the possible risks in industrial methods of building construction in the technical, executive, economic and support, political, cultural, social and environmental aspects were identified and categorized. In order to identify the main risks, the Delphi method based on experts and elites’ comments were used. Out of 48 identified risks, 18 risks were selected which were classified into five scopes of economic, executive, technical and cultural, social and political support. Then, using the DEMATEL method and the two criteria of intensity of interaction and impact relation map, the effect of each of these factors on the objectives of the probability of occurrence and finally the importance of each risk were determined. Ranking these factors showed that executive, economic and support scopes were the riskiest scopes of industrial construction methods. In addition, the results of the research showed that based on both criteria, inappropriate and inefficient management were the greatest risk factors followed by the risks of false selection of construction techniques, lack of knowledge and technical skills of executives, existence of conflict between executives and stakeholders, budget deficits, unseen delays in the project and price fluctuations and inflation.
