In traditional urban underground pipe gallery design, construction typically begins only after collecting the finalized drawings and submitting them to the pipeline integration team. This team then develops a comprehensive construction plan, which the construction unit subsequently follows during execution.

During construction, if a pipeline conflict arises, it often requires revising the original design and reworking completed sections. However, Building Information Modeling (BIM) technology offers a different approach. BIM enables comprehensive construction simulations before actual work begins, significantly reducing on-site problems. For example, it can predict potential collisions when laying underground pipelines, allowing designers to address conflicts early in the process. This proactive approach minimizes design changes during construction, improving both efficiency and quality.
BIM technology has been integrated into municipal pipe gallery design, not only facilitating the layout of underground pipe networks but also allowing for construction simulation and design correction through virtual modeling. Unlike traditional 2D pipeline design, where overlapping lines may not appear conflicting and often go unnoticed, BIM provides a holistic view of the project. It highlights local sections, road intersections, and other critical areas that 2D designs might miss. As a result, BIM surpasses the limitations of 2D by offering enhanced visualization and functionality throughout the design and construction phases.
