The dissertation examines the current relevance of the need for economically useful and reliable rational planning of the entire construction site, construction mechanisms and temporary infrastructure. The goal of this dissertation is to improve construction site planning by creating a construction site planning optimisation model using photogrammetry. The most appropriate version of the construction site plan is chosen based on arguments evaluating the current condition and project solutions in an automated way. The dissertation consists of an introduction, three chapters, a summary of the results, lists of used literature, and the author’s publications on the dissertation topic. The introduction discusses the research problem, and the relevance of the work, describes the research object, formulates the purpose and tasks of the work, describes the research methodology, the scientific novelty of the work, the practical significance of the work results, and defensive statements. The first chapter analyses scientific literature on mathematical models, construction planning software, and photogrammetry. At the end of the chapter, conclusions are formulated, and the tasks of the dissertation are clarified. The second chapter describes the created mathematical model of the construction site plan, details the determination of the current situation, the determination of the need for construction mechanisms and temporary infrastructure, the selection of the construction site plan representation method, the spatial planning, and the optimisation of the construction site. The information required for the calculation of the need is obtained from the photogrammetric model of the existing condition and the BIM model of the newly constructed structure. Finally, the mathematical model allows for rational construction planning, assessing existing and newly constructed structures, built-up or vacant areas, the need for construction mechanisms and temporary infrastructure. The third chapter presents a case study of photogrammetry. The BIM model of a building that exists, in reality, is simulated, its photogrammetric model is created, and the accuracy of the photogrammetric model is determined. The sequence of operation of the mathematical model is tested by graphically representing the selection of construction mechanisms and temporary infrastructure.
