BIM technology (Building Information Modeling) is increasingly used in the design and implementation of cubature and infrastructure investments. Polish designed offices are made possible by high-quality executive designs produced using modern BIM tools, thus generating increased benefits for the client or investor. The basic advantage of a project made using BIM technology is the three-dimensional model. Having a good and accurate three-dimensional model makes carrying out analysis on the project more effective, including the running of important simulations for the evacuation of people from the designed building. The aim of the paper was to analyse available solutions in BIM applications in regards to safety during the operation of the designed office building. This paper presents how BIM technology can be used to create such simulations, and to review various variants and related documentation.
