Abstract
The paper deals with two very current topics – brownfields and BIM models, building information models. While BIM models of buildings and their interconnection to other systems (GIS) are both, in the Czech Republic and internationally, the issue discussed not only by the professional public, but also by politicians, brownfields and their databases are at the edge of interest in political-decision-making. It can be said that the brownfield database, ie areas with predominantly defective and unused buildings, with the data contained therein can form the basis for data models of these building and areas. This article outlines the information, data and knowledge of brownfields used by all professions in the AEC industry and examines their compatibility with BIM models of building or areas, that go hand in hand with the current BIM transition in the Czech Republic.

Summary
Brownfields revitalization is very current topic in the world and in the Czech Republic at these times. This topic, encounters few obstacles, as for example complex property-law relations, financing of revitalization [1], compliance of the project with landscape-use planning documentation, and others. The absolute fragmentation when registration of sites classified as brownfields is one of the most significant revitalization problems in the Czech Republic is. This fragmentation happens due to the absence of the legislative framework for brownfields in the Czech Republic, where the term “brownfield” is not defined in this legislation.
