How to turn a country into a BIM Country and how to measure its BIM maturity index

Turning a country into a “BIM Country” (Building Information Modelling) involves a systemic digital transformation of the construction sector, led by the public sector and adopted by the private sector. BIM maturity is measured by assessing the level of adoption of standards, technology, processes, and training in the market. But how to turn a country into a BIM Country? What should the Roadmap be? BIM implementation at the national level is not only technological; it is a strategic and cultural change and perhaps it should involve establishing a Government Mandate and National Strategy as in the United Kingdom, or running pilot projects in the public sector to test standards and adjust the strategy before full adoption as in Germany… We must find the right facilitator for this. And then we would have to measure its BIM Maturity Index, that is, the maturity index that measures continuous improvement in quality and collaboration within the market. There are components of Macro-maturity (as a national measurement and to measure a country, the “BIMe Initiative” uses eight components for “macro-maturity”) but how do we measure organizations, people? Spain implemented a four-phase plan (2024-2030) that increases the maturity requirement (Level 1 to Level 2) in public contracts, based on the monetary value of the tender. But is this enough?
