Company deals primarily with digitization of project documentation and implementation of BIM in existing projects and built structures. These processes involve the conversion of existing 2D project documents into 3D (BIM-based models) and the creation of a BIM model of constructed structures.BIM systems in architecture aim to make it easier for future and existing users to use structures, so that the client (user) at any given time has information about the implemented systems in the architectural framework that it uses. By doing so, it is possible to achieve savings in the exploitation of facilities, and to improve both the efficiency of work and facilitate future implementation.
