This research presents a comprehensive framework for quantifying the benefits of Building Information Modelling in construction. Through industry insights and surveys, the study validates formulated equations and integrates case studies from the Swedish construction sector. Results reveal increased costs in the design phase but indicate time and cost savings during design and construction. Operational benefits, notably in maintenance planning and energy efficiency, constitute a substantial portion of the total estimated benefits. The study introduces a unified quantification methodology, demonstrating an investment rate of 16.1 % and 10.17 % for cases A and B, respectively. This research contributes to the ongoing discourse on BIM adoption, offering valuable insights and methodological advancements for industry practitioners.
