Under the title “Cost-benefit analysis of the BIM method – a comparative case study” M. Mellenthin Filardo, J. Melzner, A. Lammert, M. Korn, R. Windisch, and C. P. Fürstenberg examine the monetary and qualitative effects of BIM in building construction practice.

As part of a systematic cost-benefit analysis, three key use cases—coordination of specialist trades, quantity and cost determination, and building documentation—are analyzed in a comparative study design. The current state of application ("status quo") is compared with an ideal BIM implementation ("status futurus"). The empirical data is based on real construction projects.

The results show that BIM application has an improved cost-benefit ratio in all cases examined. The efficiency gains are particularly evident in the coordination of specialist trades and in quantity and cost determination. The study thus provides quantitative evidence for the economic efficiency of the BIM method and supports evidence-based decision-making in the context of the digital transformation of the construction industry.

The research was conducted as part of the project "Cost-benefit analysis of the use of BIM in building construction" (file number FWD 2–10.08.17.7–22.02) funded by the Bundesinstitut für Bau-, Stadt- und Raumforschung (BBSR)  (BBSR).
