As in all aspects of our lives, development and innovative solutions reveal every day. Life without progressive things, such as a mobile phone or the Internet, is unimaginable for man living in our modern age. Towards the current trend called Industry 4.0., which is the trend of data exchange and automation in manufacturing technologies, people are on the brink of big changes. Current digitization in our everyday lives helps us to enhance their quality. As many other branches, AEC (architecture, engineering and construction) industry also goes through the enhanced digitization process. As an effective tool following trend Industry 4.0 in AEC industry, BIM - Building Information Modelling (or Management) Technology has proven itself. Nowadays, in many not even European Countries, the BIM Technology is in different levels of using. Connected to it, BIM is on different phases of implementation into legislation these days. In some countries, using BIM Technology for new building design is compulsory for public service contracts, building infrastructures or for all building without the difference. In order to be competitive, in the Czech Republic's Legislation, the trend is the same. But there are many barriers for BIM implementation, or the BIM adoption. Proper solutions for many key topics is necessary to find before the introduction of BIM for widespread use. Of course, finding these solutions take a lot of time, expenditures and failures to reveal the most optimal solution of implementation. The Czech Republic is one of countries which already started with processes connected to BIM implementation and adoption. At these days, country is solving many issues connected to BIM implementation. This paper is a brief presentation of them and it reveals the reasons and ways to achieve this.
