The EU BIM Task Group completed the important work of looking at the cost benefit of BIM in public tenders. The document aims to build the case for the introduction of BIM in public procurement for individual public projects by demonstrating costs and benefits from the perspective of public clients. It reflects the analysis performed during the project and the results obtained. It is conceived as an informative, easy-to-read guide meant to prepare the public stakeholders to apply the model developed for evaluating the costs and benefits of using BIM in public tenders.
The Cost-benefit Analysis (CBA) user Handbook is structured in five main chapters:
- Introduction to the topic, presenting the purpose of the handbook to public entities.
- Insights on the present status of BIM adoption in the public sector, through literature research, interviews and an on-line survey.
- Development of the CBA tool, describing the approach and methodology used to create it, including a step-by-step guide for using the tool.
- Practical implementation of the CBA tool in six case studies, representing various types of projects (small-scale infrastructures and buildings with differing budgets and covering diverse phases of the lifecycle), to show validation of the model.
- Conclusions of all the work performed.
