The approach to volumetric formation of aggregative architectural–design structures presented in the article demonstrates that combining morphological maps with compatibility rules, a standardized data hierarchy (WBS → PBS → SBS), and open BIM standards creates a controlled, reproducible, and transparent design process. Morphological axes, compatibility matrices, and formalized constraints convert the «creative space» into a set of valid configurations suitable for automated generation and filtering. The integration of IFC/LOIN/ISO 19650 with IDS templates and BCF exchange ensures data traceability, decision verifiability, and CDE discipline throughout the model lifecycle. Implementing the GFE (Gen — Filter — Explain) cycle records the logic of decision making: alternatives are generated under hard constraints, filtered by multi-criteria evaluation (geometry, codes, engineering, 4D / 5D / 6D), and the rationale is stored in a decision log for audit.
Linking with 4D / 5D and formulating RCPSP transfers compositional schemes into construction-site reality: resource peaks are reduced, deliveries are coordinated, and conflicts with temporary works are revealed. Adding 6D attributes and preparing a digital twin narrows the operational performance gap, enables model calibration with field data, and supports FDD/predictive maintenance. Practical risks boil down to library quality, uncertainties in input data, and discipline of work within the CDE. The proposed tools — an «uncertainty passport», library governance, and standardized IDS profiles — minimize these risks, increasing the robustness of solutions.
Thus, the aggregative approach in BIM serves as an effective bridge between architectural creativity and engineering feasibility, between authorial intent and production logistics. It reduces clashes, accelerates coordination, improves cost and schedule predictability, and lays the groundwork for large-scale deployment of digital twins in urban construction. Further research should focus on automatic generation of IDS from morphological rules, unification of product libraries with certified Psets, integration of energy modeling and life-cycle assessment into the early GFE filter, and standardization of uncertainty passports. In education, it is advisable to implement studios where students complete the full WBS → PBS → SBS cycle and publish explanation dashboards in the CDE, training skills in transparent, data-driven design. This will raise the quality of decisions and their social legitimacy and resilience.
