    Building Information Modeling (BIM) adoption is still evolving in Nigeria and there are no many examples of its usage for project execution by industry practitioners. There is a dearth of studies on how barriers to BIM adoption can be overcome. Following the identification of barriers to BIM adoption from literature, an online survey approach was used to investigate the perception of Nigerian construction industry professionals on the significant barriers to BIM adoption based on a five point Likert scale from 1 “not at all a barrier” to 5 “extreme barriers”. Class means difference among professional group was used to identify barriers to BIM adoption and a discriminant analysis was used to established disagreement among the respondents. The result shows that, the various groups have equal mean discriminant function score on 16 barrier factors to BIM adoption, indicating agreement in the opinion of the groups on these factors. However, 5 items have the most significant predictive power in differentiating the professional groups from the standpoint of perceived barriers to BIM adoption. Implying that there is difference of opinion between the group on whether the 5 factors constitute barriers to BIM adoption or not. The factors in order of magnitude are: clients low level of awareness, lack of funding, poor power supply, legal uncertainty and lack of transparency. The barrier factors identified in this study will assist industry stakeholders in formulating appropriate strategies to overcome them in order to ensure successful BIM implementation. Findings from this study indicates the need for construction industry stakeholders to encourage practitioners to adopt BIM at various level for project execution.
