Corridor MEP pipeline integration and hanger-layout optimization using BIM-based genetic partitioning and performance analysis

In recent years, with the increasing demands for architectural design, the complexity of mechanical, electrical, and plumbing (MEP) systems has also increased, making the modular construction of integrated MEP systems a focal point of research in the industry. However, traditional two-dimensional (2D) design methods have numerous limitations in the modular design of MEP systems, making it difficult to achieve effective system integration and coordination. This often results in inefficiencies, information inconsistencies, and frequent design conflicts. To address these issues, this study explored how to leverage building information modeling (BIM) technology to improve the efficiency of MEP system integration, modular division, and optimization. Based on the BIM technology, an automated system for MEP modular division and optimization was developed. By utilizing high level of integration and visualization capabilities of BIM, information from various disciplines can be integrated into a single three-dimensional (3D) model, enabling standardized module division, automated optimization, and the design of internal supports and hangers. The results of the study indicate that the proposed genetic algorithm-based MEP modular partitioning method significantly improves the efficiency of pipeline automation partitioning, achieving an approximately 45%–65% increase in partitioning efficiency compared to traditional methods. In addition, the proposed method successfully avoids conflicts with connector locations and further demonstrates the broad applicability of BIM technology in the design and modular construction of complex building MEP systems.
