The strengthening of frame buildings during reconstruction is a complex engineering task that requires the coordinated consideration of structural reliability, technological efficiency, and long-term sustainability. In practice, the selection of structural-technological solutions is often based on expert judgment and fragmented criteria, which limits transparency and increases uncertainty in decision-making, especially under constrained reconstruction conditions.
This paper proposes a conceptual model for quality assessment of frame strengthening as a core component of a decision support system. The model is based on a systemic and life-cycle-oriented approach and integrates three interacting groups of criteria: reliability, efficiency, and sustainability. Quality is interpreted as an integral result of the interaction between these criteria rather than as a single performance indicator.
The proposed structure formalizes the hierarchy of criteria and indicators, allowing the assessment process to account for structural performance, technological feasibility, resource efficiency, environmental impact, and organizational stability throughout the life cycle of the building. The model does not represent a comparative optimization algorithm but provides a methodological framework for ensuring logical consistency and transparency in the evaluation and substantiation of strengthening solutions.
The developed conceptual model creates a theoretical basis for further implementation of digital decision support tools, multi-criteria analysis methods, and BIM-based quality management systems in building reconstruction projects.
