Introduction. The rapid development of BIM technologies in the construction industry is accompanied by growing requirements for the quality of architectural and structural models, but the lack of a systematic approach to multi-level verification leads to design errors, collisions between systems and non-compliance with regulatory requirements. Integrating BIM modeling with building codes and legal standards is critical to ensuring safety, structural integrity and regulatory compliance. Existing quality control methodologies do not ensure comprehensive consideration of the interaction of architectural and structural elements at all stages of design.
The purpose of the udy is to develop a scientifically based methodology of a multi-level quality control system of architectural and structural BIM models, taking into account the current regulatory and legal framework of Ukraine and international BIM design standards.
Materials and methods. A systematic approach to the creation of an automated system for evaluating the quality of BIM models, which includes data extraction/analysis, storage and visualization modules, is applied. Comparative analysis of international automated compliance verification (ACC) systems in the BIM environment, modeling of interdisciplinary coordination, expert evaluation and validation on real projects was used.
Results. A methodology for a five-level quality control system has been developed, combining: 1) automated geometric verification and collision detection; 2) verification of architectural and planning solutions according to the DBN (space, accessibility, constructiveness); 3) validation of constructive solutions according to structural calculation norms based on machine-readable rules; 4) integration assessment of system compatibility; 5) expert verification of special norms and security standards. The mechanisms of the IFC federation of openBIM models to increase interoperability are outlined.
Conclusions. An integrated system for evaluating the quality of 3D BIM models with automatic extraction of information for configured checklists is proposed. A matrix of compliance of development levels (LOD) with Ukrainian standards at the design stages and a methodology of built-in code verification in the process of BIM modeling with visualization / simulation of requirements have been formed. The methodology provides systematic interdisciplinary quality control and supports the digital transformation of the construction industry of Ukraine.
