The present invention relates to a system and method for automatically generating a complete and precise bill of materials by learning the structural and logical relationships between design components using a graph neural network (GNN) from heterogeneous design data sources such as 2D CAD drawings, 3D BIM models, and specifications, and by predicting and interpolating the actual quantities to be input at the time of final completion from incomplete initial design data using a generative adversarial interpolation neural network (GAIN). The effects according to the present invention are as follows. First, the present invention precisely interpolates missing attributes using a Generative Adversarial Interpolation Network (GAIN) even in incomplete situations where input data, such as drawings, BIM, and specifications, is heterogeneous and some information (thickness, material, specifications, etc.) is missing. Through this, the reliability and integrity of input data, which forms the basis of quantity calculation, can be dramatically improved even in the initial design stage where data quality is low. Second, active risk management and design quality improvement through learning design change trajectories. Unlike existing methods that simply sum dimensions on drawings or predict only the final result, this invention predicts future change risks in advance by learning the trajectory of design changes through LSTM-based time-series historical analysis. By providing real-time feedback to the designer regarding warnings and alternatives for potential change-inducing factors, it fundamentally prevents unnecessary design changes, maximizes the accuracy of completion predictions, and minimizes the risk of increased construction costs and project delays. Third, it structurally learns the physical support, connectivity, inclusion, and spatial adjacency relationships of a building through a Graph Neural Network (GNN). This enables the automatic generation of a consistent bill of materials that aligns with the structural hierarchy and engineering correlations of the entire building (e.g., the relationship between column load and foundation reinforcement quantity), rather than merely calculating the fragmentary quantities of individual objects. Fourth, by utilizing a Large Language Model (LLM), the generated bill of materials items are double-checked to ensure they logically align with text-based specifications and building codes. By comprehensively evaluating semantic similarity and logical validity, legal and technical risks are minimized by preventing errors in advance where the quantity is correct but the specifications are incorrect (e.g., standard gypsum board vs. fire-resistant gypsum board). Fifth, by applying X-ray Influence Analysis (XAI) technology to the results generated by AI, it explains, using 3D heatmaps and causal text, which object (node) on the drawing is the origin of a specific volume increase. This resolves the 'black box' problem of AI and provides a reliable environment where users can clearly trace the basis of calculations. Sixth, regarding scalability, it enables risk-based estimation by providing multiple scenarios in the form of 'average value + range of variation (confidence interval)' rather than a single predicted value. Furthermore, by linking the calculated quantity data with cost and schedule data, it provides full-cycle project management efficiency that allows for the immediate simulation of the impact of design changes on total construction costs (5D) and construction duration (4D).
