The investigation of the drone technologies effectiveness as the basis for information modeling of the building systems life cycle

The article considers digital technologies frequently used in the construction industry, ensuring the efficiency of construction of buildings and structures at various life cycle (LC) stages. The article is based on a review of scientific publications by domestic and foreign researchers and personal re-search of the authors. The main capabilities and advantages of using unmanned aerial vehicles (UAVs) are presented in tabular form for each LC stage of a real estate object. It has been established that drone technologies are mainly used at the buildings and structures construction stage to ensure labor protection and safety, quality control, analysis of real data at the construction site and compari-son with design documentation, delivery (submission) of materials from on-site warehouses to the design site. The advantages of using UAVs at the pre-project stage are revealed, including reduced duration of topographic work, measurement accuracy, and work in hard-to-reach places. The possibil-ity of expanding the use of drone technologies at the stage of construction of a real estate object is noted, namely when performing individual technological processes by changing or improving the design and functional parameters of the UAV
