Building Information Modelling (BIM) is increasingly recognized as a transformative technology in global construction, with benefits such as enhanced cost control, reduced rework, enhanced collaboration, and better lifetime asset management.  However, its adoption in Nigeria's construction sector is still unequal and slow.  This paper uses scholarly research, policy documents, and comparative institutional reports to examine several barriers to BIM adoption in Nigeria.

The 10 themes of impediments identified were: technological, financial and economic, educational and human capital, organizational and cultural, legal and regulatory, market and client-driven, comparative and Cross-National reflections, influence of the informal sector, institutional Readiness and Capacity Deficits, and socioeconomic factors.  The findings indicate that the industry has challenges such as a significant skills gap, costly software, inadequate digital infrastructure, and resistance to organizational change.  The lack of institutional support and the absence of a national BIM policy exacerbate the challenges.

Most significantly, the research highlights barriers, such as the dominance of the unorganized sector, a lack of institutional capacity, and macroeconomic instability, that significantly affect Nigeria's adoption of BIM.  These findings demonstrate the need for a thorough, systems-thinking approach to BIM implementation.

The report concludes that in order to solve these challenges, Nigeria must put in place a coordinated approach, including all pertinent stakeholders, including the government, educational institutions, the business sector, and professional groups.  Funding sources, curricular integration, capacity-building initiatives, and policy development are essential to advancing BIM adoption from theory to reality.  In addition to contributing new perspectives to the discussion, this analysis establishes the framework for future empirical research and legislative efforts.
