The thesis discusses the integration of augmented reality technologies into the construction industry. The starting point of the thesis is the digitalization of construction processes, particularly the development of BIM approaches, which enable better management of project information and the exchange of data among project stakeholders. The thesis then presents the basic concepts of the reality–virtuality continuum, the differences between the various forms of reality, and the historical development of AR technology. Particular emphasis is placed on the operation of AR systems, especially tracking, positioning, and spatial registration technologies, which enable digital elements to be displayed in the real environment. The main part of the thesis focuses on the use of AR in construction. Devices that can be used for AR, such as mobile devices and head-mounted displays, are presented. In the practical part, two conceptual applications of AR on a specific construction site are presented: checking the position of mounting elements for prefabricated columns and checking the excavation of strip foundations, together with an assessment of the required equipment, costs, and potential savings. The thesis demonstrates that AR, in combination with BIM models, can improve spatial understanding, communication among project stakeholders, quality control, progress monitoring, MEP coordination, building maintenance, and occupational safety. Despite its significant potential, AR does not yet represent a standalone solution to all challenges in the construction industry. Its effectiveness depends on the quality of BIM models, the accuracy of spatial alignment, device capabilities, implementation costs, and users’ readiness to adopt new technologies. AR should therefore be understood as a supporting technology that complements existing methods and can contribute to more efficient and reliable management of construction processes.
