The role of using the database of materials and equipment in the implementation process of Building Information Modelling

One of the new processes and technologies that solve many problems of construction projects is Building Information Modeling (BIM). BIM is not widely used in Iran, while in other countries, its culture is settling at a more favorable pace. Ideal modeling so that the micro-models are realistic and have information such as construction time and cost, construction companies, quality, etc, is a time-consuming and costly task, this issue reduces the tendency of stakeholders to implement BIM. What is the role and effect of using databases of materials and equipment in each of the stages of BIM implementation in construction projects? if there is a comprehensive database in the field of BIM, which BIM functions will be facilitated and which stakeholders benefit most from this database, are the questions that this paper seeks to answer. In the present study, after reviewing the literature related to the subject and recognizing the generalities and definitions of the database of materials and equipment, as well as its benefits and effects, semi-structured interviews were conducted with 16 experts in this field, using a qualitative method and then a content analysis. The results show that the use of materials and equipment database is the most used in the detailed design stage and it’s most used in cost estimation, Quantity Take Off and clash detection and also the consultant and employer benefit the most from this database.KEYWORDS
