The Sri Lankan construction sector is crucial to the country’s economic growth but faces several challenges that hinder project success. This research explores the potential of Building Information Modelling (BIM) to address these challenges and identifies strategies to overcome the barriers to its adoption in Sri Lanka. The study involved 64 construction professionals from various organizations, selected through snowball sampling. Structured interviews were conducted to assess the current state of BIM usage, adoption levels, proficiency, and the perceived challenges and opportunities within the sector. Content analysis was employed to interpret the data and extract meaningful insights. The findings highlight several significant barriers to BIM adoption in Sri Lanka. The findings highlight several significant barriers to BIM adoption in Sri Lanka. These include a lack of knowledge about BIM (70%), inadequate BIM software knowledge (52%), insufficient IT infrastructure (57%), and a lack of education and training (49%). Despite these challenges, the study also identifies potential strategies to overcome these barriers, such as enhancing BIM education at the undergraduate level and increasing workshops, courses, and specialized conferences related to BIM. This study contributes to filling a critical knowledge gap by developing innovative strategies tailored to the local context, which can enhance the efficiency and effectiveness of construction projects through successful BIM adoption. While the findings are most relevant to Sri Lanka, they may also be applicable to similar developing countries. However, the results are based on current data, and future technological and regulatory changes could impact the applicability of the proposed strategies. The research concludes that the effective use of BIM-based applications can significantly improve service delivery efficiency in the Sri Lankan construction industry.
