This invention relates to the field of BIM technology, specifically disclosing a BIM-based full lifecycle engineering project collaborative management system. The system includes a cross-sectional cavity distribution analysis module, a pipe group cross-sectional reduction zone identification module, a bearing capacity reduction coefficient quantification module, a floor slab performance distribution mapping module, and a project collaborative instruction push module. This invention reads the geometric characteristic parameters of embedded pipelines and the structural attribute parameters of concrete floor slabs from the MEP (Mechanical, Electrical, and Plumbing) BIM model and the structural BIM model. It establishes an analysis section to calculate the projected area and vertical occupancy range of pipeline cavities. Based on the effective cross-sectional reduction rate and spatial connectivity, it identifies the pipe group cross-sectional reduction zones, quantifies the bearing capacity reduction coefficient, and maps it to the BIM model to generate a structural performance distribution map. Based on the lifecycle stage, it generates differentiated collaborative management instructions and pushes them to the corresponding participants. This achieves cross-analysis of the structural model and the MEP model at the cross-sectional level, solving the problem of unidentified pipe group cross-sectional reduction zones throughout the entire lifecycle.
