METHODOLOGICAL SUPPORT FOR ASSESSING THE QUALITY OF TRANSITION STAGES TO EUROPEAN NORMS AND STANDARDS IN ACTIVITIES OF AN ARCHITECTURAL AND CONSTRUCTION COMPANY

The article reveals the essence and components of the applied mechanism of methodological support for assessing the quality of the stages of transition of architectural and construction companies to European standards in the context of globalization, digitalization, and the requirements of sustainable development. Based on the analysis of international and national studies, the structure of an indicative assessment model has been substantiated that covers eight key areas of transformation: from regulatory adaptation and digital transformation to the implementation of ESG principles and certification in accordance with ISO. A formula for the integral indicator Q_total has been proposed, which makes it possible to track the overall progress of the company’s transformation. The toolkit is based on clearly defined indicators Q₁–Q₈, each of which evaluates a separate stage of adaptation. The algorithm of their calculation, practical application examples, and comparative analysis criteria have been substantiated. The study analyses open data from 10 leading Ukrainian companies that are implementing BIM, energy management systems, and international certifications. A comparative assessment with the German company ZÜBLIN AG made it possible to identify gaps in the implementation of digital and ESG components, which proved important for further improvement of the methodology. The material is illustrated with quantitative results in tables, goal achievement diagrams, and an applied interpretation of indicators as tools for managerial decision-making. A conclusion has been drawn about the expediency of applying the developed methodology for strategic monitoring, increasing investor trust, and preparing for participation in international tenders. The proposed approach makes it possible to form a systemic development scenario for an architectural and construction company in the context of European integration, to increase its competitiveness and compliance with sustainable development criteria. The methodology can be used both at the level of management audit and for educational and methodological purposes in the training of industry specialists.
