Construction Projects

Recently, Building Information Modeling (BIM) has emerged as a new technology in the construction industry, which is gradually gaining popularity among stakeholders. Despite the importance of BIM, the literature review shows a gap in the evaluation of BIM applications in Iran. Therefore, the aim of the current research is to evaluate the applications of BIM in construction projects. Since the evaluation of the most appropriate option is a multi-criteria decision-making problem. Therefore, decision makers use preferences that are uncertain in evaluating options. Rough's theory, which is efficient in such conditions, is used. First, by using the concept of Rough's theory to transform the preferences of experts and the combined method of Analysis Hierarchy Process (AHP) and VIKOR, is used for evaluation. The results show that the proposed decision method is effective improved objectivity in BIM application evaluation under subjective condition.

INTRODUCTION: Every year, a number of citizens, especially workers, lose their lives or are injured in fires, and many assets are destroyed by fires. In fact, the dimensions of these losses are also increasing with urban and industrial development. The purpose of this research is to identify and rank the supervisory and instrumental criteria of firefighting and rescue in controlling the risk of accidents in construction projects in Tehran. METHODS: In this applied-descriptive research, library and questionnaire methods were used and then the main criteria were prioritized using the Analytic Network Process (ANP) technique. About 10 construction experts (mass builders) in Tehran were selected and studied based on available sampling. FINDINGS: In this research, in the first stage, based on the opinions of experts, 42 sub-criteria were screened and selected as appropriate sub-criteria, and in the second stage, the main research criteria were prioritized. CONCLUSION: Based on the results, the criteria of "safe emergency evacuation instructions", "appropriate and sufficient emergency exits", "management of electrical equipment", and "safe emergency evacuation instructions" with normalized weights showed that the sub-criteria of "gas welding and flame cutting work must be performed by skilled workers", "adequate emergency lighting", "prevention of generator overheating", and finally "location of emergency signs" are in the first priority.
