Abstract
Building Information Modelling is revolutionizing the workflow and processes in the industry and the design approach in creating building models. Among the stages of design, conceptualisation is being affected by BIM adoption as well. BIM has brought a lot of benefits to design but still designers are struggling to implement BIM at the very early stage of the design process. Thus, this study has been conducted to investigate how BIM is transforming concept design process and what could be the possible answer to overcome the barriers of BIM adoption at conceptualisation. From previous studies, the transformation of the design process within BIM methodology is explained and also general features of concept design stage are depicted to study its transformation within the evolution of Information Modelling. The study preferred reporting items for systematic reviews and Meta-Analyses (PRISMA) was used to identify inefficiency in construction design and conceptual phase, its effect on project quality and budget. To identify benefits and barriers to BIM at the design and conceptual phase this study presents preliminary findings based on twenty journal articles from an extensive review of a larger study. Findings from the review of the journal articles revealed the benefits and barriers to BIM at the design and conceptual phase and identify inefficiency in construction design and conceptual phase and its effects on project quality and budget.
