Impact of Building Information Modelling on Construction Project Performance in Abuja Municipal Area Council, Nigeria

Abstract

This study examined the impact of BIM on construction project performance by assessing awareness, adoption, perceived benefits, and barriers to implementation among construction professionals. A mixed-methods research design was employed, involving a questionnaire survey of 529 construction professionals across in AMAC, Abuja, Nigeria. A total of 515 valid responses were analysed, representing a 97.4% response rate, while qualitative insights were obtained through interviews with 15 BIM experts. Quantitative data were analysed using descriptive statistics, and qualitative data were subjected to thematic analysis. The findings revealed a moderately high level of BIM awareness (overall mean = 3.39), with awareness of the BIM concept recording the highest mean score (3.54). BIM adoption was highest for design visualization and quantity take-off, while advanced applications such as 4D scheduling and facility management remained limited. Respondents agreed that BIM positively influences project performance (overall mean = 3.44), particularly in design quality (3.55) and collaboration (3.47). The principal barriers were the absence of a national BIM policy (3.88), inadequate technical skills (3.78), and high software costs (3.75). The study concludes that strengthening policy support, professional capacity, and organizational investment is essential for accelerating BIM adoption and improving construction project performance in Nigeria.
