A Cost–Benefit Analysis of BIM Methodology Implementation in the Preparation and Construction Phase of Public Sector Projects

This article evaluates both economic and non-economic benefits associated with the implementation of Building Information Modeling (BIM) and the digitization of processes within public sector construction projects of the Czech public sector organization (PSO). The study is based on empirical data from three real projects: the Children’s Sanatorium with Speleotherapy, the Air Rescue Services Base, and the Neurorehabilitation Center. For one of those projects, cost–benefit analysis (CBA) was applied to quantify direct financial savings and indirect operational improvements; however, other projects supported the investigation. Data sources include real project data such as BIM documentation and project budgets. The analysis reveals that BIM adoption led to measurable reductions in rework, improved coordination among stakeholders, and enhanced facility management efficiency, resulting in a cost–benefit ratio of more than 4.5. Results from this article support the results of other already made research and prove the consistency of those results. These findings demonstrate the practical value of BIM in public infrastructure delivery and provide actionable insights for decision-makers seeking to improve project outcomes through digital transformation.
