The rapid development of BIM technologies in the construction industry is accompanied by growing requirements for the quality of architectural-structural models, however, the lack of a systematic approach to multi-level verification leads to design errors, conflicts between systems, and non-compliance with regulatory requirements. Integration of BIM modeling with building codes and legal standards is critically important for ensuring safety, structural integrity, and compliance with regulatory requirements.
The research objective is to develop a scientifically grounded methodology for a multi-level quality control system for architectural-structural BIM models, taking into account the current regulatory-legal framework of Ukraine and international BIM design standards.
Materials and methods. A systematic approach was applied to create an automated BIM model quality assessment system, including a data extraction and analysis module, data storage module, and visualization module. Comparative analysis of international automated compliance checking (ACC) systems for structural calculation codes in BIM environment, interdisciplinary coordination process modeling, expert assessment, and validation on real projects were used. Results. A five-level quality control system methodology was developed, combining: (1) automated geometric verification and collision detection between architectural and structural elements; (2) verification of architectural-planning solutions according to DBN, including spatial characteristics, accessibility, and constructability; (3) validation of structural solutions in accordance with structural calculation codes using machine-readable rules; (4) comprehensive assessment of architectural-structural systems integration for compliance with design requirements; (5) expert verification of compliance with special regulatory provisions and safety standards. Mechanisms for IFC openBIM model federation were defined to improve interoperability between architectural and structural project sections.
Conclusions. This research created for the first time an integrated 3D BIM model quality assessment system using specialized modules for each discipline and automatic information extraction for compliance assessment with configured checklists. A matrix of correspondence between levels of development (LOD) and Ukrainian building codes at different design stages was developed. A methodology for integrating building code compliance checking directly into the BIM modeling process with visualization and simulation capabilities for compliance requirements was proposed.
The proposed methodology provides a systematic interdisciplinary approach to quality control of architectural-structural BIM models and contributes to improving construction design efficiency while fully complying with regulatory-legal requirements, creating a foundation for digital transformation of Ukraine's construction industry.
