The study presents a comprehensive analysis of the relationship between the use of advanced construction technologies and the challenge of preserving authenticity in the restoration of architectural heritage sites. The relevance of the topic is determined by increasing tensions between the need to extend the service life and functional readaptation of historic structures and the risk of losing their material and intangible character as a result of overly invasive technological interventions. The aim of the study is to conduct a holistic analysis of the interdependent relationships between modern construction technologies and the criterion of authenticity in the tasks of restoring architectural monuments. The methodological foundation consists of a systematic analysis of specialized publications, which examine the possibilities of applying digital modeling technologies (BIM), laser scanning, additive manufacturing, and new composite materials in restoration practice. As a result, a multi-level methodology for assessing the authenticity of an object is described, and an algorithm for selecting technological solutions is considered, taking into account the historical and cultural value of the monument, its technical condition, and the planned functional load. It is concluded that the judicious integration of innovative technologies not only prevents a decline in the genuineness of the building but can also enhance its level by minimizing physical intervention, accurately reproducing lost elements, and generating detailed digital documentation. The practical significance of the study is manifested in its applicability for conservation architects, engineers, monument guardians, and specialists in the field of construction sciences.
