Abstract: Despite significant growth in Rwanda’s construction sector, challenges persist including project delays, cost overruns, and inefficient resource utilization. This study examined the impact of Building Information Modelling (BIM) on construction project efficiency in Rwanda, focusing on the Amahoro Stadium Modernisation project in Kigali. Using a mixed-methods case study approach, 200 construction professionals from engineering, project management, operations, IT, and finance departments were selected through simple random and purposive sampling (Slovin formula, 5% margin of error) from a population of 400. Data were collected via structured questionnaires and semi-structured interviews, then analysed using descriptive and inferential statistics (Pearson correlation, multiple regression, and ANOVA). Reliability was confirmed with Cronbach’s alpha of 0.82. Findings revealed strong positive effects of BIM on construction efficiency, with 93.50% of respondents agreeing that BIM enhanced design accuracy, collaboration, and cost control (mean scores 4.29–4.32, SD < 0.70). Correlation analysis showed a significant positive relationship between BIM and project efficiency (r = 0.788, p < 0.001). Regression analysis demonstrated BIM’s significant contribution to efficiency (β = 0.35, p = 0.001), with the model explaining 83% of variance in project efficiency (R² = 0.83, F = 85.80, p < 0.001). However, 70–75% of respondents cited high implementation costs and insufficient trained personnel as major adoption barriers. The study concludes that BIM significantly improves construction efficiency in Rwanda, aligning with Vision 2050 and the Smart Rwanda Master Plan. Recommendations include investing in BIM training programmes, modernizing infrastructure, and implementing supportive policies to promote wider adoption across the country’s rapidly growing construction sector.
