**4. BIM Adoption in the World**

The United States is the world leader in the field of BIM adoption, so it is difficult to be surprised by the dominance of the North American continent. Nevertheless, Europe should be put in second place, which, using American models, but primarily creating its own dynamically developments in the use of BIM technology. Australia and Oceania were considered the next most advanced and were strong in the design modeling. Asia is followed by strong leaders in the form of Korea, Hong Kong, China, and Japan. In South and Central America, despite close patterns flowing from the leaders from the USA and Canada, BIM adoption is much slower, only individual countries decide to introduce BIM in public procurement within a few years and there are not such large countries as Argentina and Brazil. BIM adoption in the Middle East and Africa is low. Private investors are eager to implement projects using BIM technology, while public investors only use BIM for infrastructure investments involving the construction of airports or passenger service terminals (e.g., Istanbul Grand Airport, Bahrain International Airport, and Abu Dhabi Midfield Terminal). The list and brief characteristics of BIM adoption by regions are shown in Table 2.


**Table 2.** BIM adoption by regions (own study).

In Europe, the prevailing trend can be seen that western and northern countries have adopted BIM earlier and some of them, primarily the United Kingdom and Scandinavian countries are leaders on the BIM market. Southern and eastern countries are taking BIM at a slower pace. The situation is similar if we look at government initiatives, where especially Finland, Norway, Great Britain, France, and Italy dominate in the scope of solutions introduced in public procurement. Poland belongs to the second group of countries that are just planning to introduce standards or an obligation to use

significant BIM promotion.

BIM in public procurement and the adoption of BIM is slightly slower. In Poland, there is a lack of both generally used BIM standards and government support and mandatory solutions introduced in public procurement. It seems, however, that market awareness, especially of designers, is growing and dozens of public procurement, mainly related to the BIM model designing, have already been announced and carried out.
