Abstract. The article explores the scientific and technical foundations for harmonizing Ukraine’s national regulatory framework in the construction sector with international ISO standards, in particular the series ISO 3443, ISO 4463, ISO 7077, ISO 7727, ISO 7976, and ISO 12491, which regulate the requirements for geometric parameters, accuracy, tolerances, measurement methods, and statistical quality control of building structures. In the context of Ukraine’s European integration processes, the paper emphasizes the need to develop and implement identical national standards (DSTU) to ensure compliance with international requirements and to facilitate integration into the European technical space. The article provides a systematic analysis of each ISO series, revealing their structural logic, functional focus, and potential to improve installation accuracy, unify modular construction elements, reduce defects caused by measurement errors, and optimize construction processes. Special attention is given to the role of harmonization in enabling the digital transformation of the industry, particularly the implementation of Building Information Modeling (BIM) technologies, the transition to coordinated modular design, and integration into a unified European regulatory and technical space. It is substantiated that harmonization is a prerequisite for the mutual recognition of measurement results and the certification of construction products in international cooperation, which will contribute to expanding Ukraine’s export potential. It has been determined that the current regulatory framework has the potential for further alignment with the provisions of ISO series 3443, 4463, 7077, 7727, 7976, and 12491, which currently complicates the international recognition of geodetic measurement results and certification of construction products. The paper highlights the role of ISO standards as an integrated system covering modular size coordination, rules for the design and assembly of structures, organization of measurement work, compliance verification, and the application of statistical methods for quality control. The need to ensure compatibility of national standards with modern digital technologies, particularly Building Information Modeling (BIM), laser scanning, and automation of geodetic processes, is highlighted. The implementation of harmonized standards will contribute to minimizing defects and costs during construction, enhancing engineering safety, promoting the development of modular construction, and creating conditions for Ukrainian construction companies to enter international markets. The article may be useful for professionals in the fields of geodesy, design, regulation, standardization, as well as for technical regulatory bodies involved in the modernization of Ukraine’s construction sector.
