This study investigates the level of adoption of Building Information Modelling (BIM) among small and medium-sized construction enterprises in Nigeria, reflecting the ongoing technological transformation within the construction industry. A total of 182 valid responses were obtained and analyzed using IBM SPSS version 26, with emphasis placed on thirteen critical areas of construction practice where BIM application is considered relevant. The analysis reveals that BIM is most extensively utilized in construction planning, project management, construction analysis, and construction monitoring, indicating a growing recognition of its value in improving project coordination and efficiency within the Nigerian construction sector. The study further highlights the varying degrees of BIM integration across different operational areas, thereby revealing both strengths and limitations in current adoption practices. In addition, the findings provide insight into key challenges hindering wider BIM implementation, as well as opportunities for enhancing its effective use among small and medium-sized enterprises. By presenting an empirical assessment of BIM adoption, the study contributes to a clearer understanding of the prevailing adoption landscape and supports evidence-based decision-making. Ultimately, the findings offer strategic guidance for policymakers, industry stakeholders, and practitioners seeking to promote technological advancement and improve productivity within Nigeria’s construction industry.
