Today, digitization is recognized globally as a key factor in optimizing processes in many industries. Thus, in the construction industry, BIM technologies have been used for several years and bring numerous advantages to construction processes. Nevertheless, their use has not yet been fully exploited, as they offer broad opportunities for further development. Since every construction project follows a standardized life cycle, this thesis focuses on possibilities for optimizing project management processes during the construction phase using BIM models. In this respect, special focus is placed on time and cost planning, as these processes have a significant impact on the efficient performance of projects. The process requires a precise identification of project activities, determination of quantities, and processing large amounts of data to prepare reliable plans. The main objective of the task is therefore focused on finding new approaches to automate and optimize the construction planning process by introducing digitization. The first part presents the basics of traditional project management and the transition to the use of BIM technologies. It provides a theoretical background of key BIM areas that are essential for the proper implementation of BIM technologies. The second, main part describes the development of a workflow divided into two sub-processes: preparation of BIM models and databases for time and cost planning and creating 4D and 5D BIM models. Each step in the workflow is supported by theoretical foundations, research findings, advantages and disadvantages, guidelines, and results. A set of software tools used is described as we go along, as well as the functionality of a custom-developed program for processing IFC schemes and automatic quantity take-off. In the third part the workflow is implemented on a study case, resulting in a functional 4D and 5D BIM model. A connection is established between the three key software tools used, enabling automatic updating of the plan when changes are made to the model. In conclusion, the use of BIM technologies in accordance with the proposed workflow is justified and offers numerous advantages, especially in large-scaled projects. However, a systematic approach and a high-quality BIM model are required to achieve these advantages.
