This invention relates to the field of data processing, and more specifically, to a method and system for constructing high-speed engineering BIM models based on data analysis. The method includes: collecting data including point clouds of a BIM design model, point clouds of the construction site, and GIS geographic information of the project area; calculating the dynamic weight of each point cloud at the construction site; constructing a weighted ICP objective function using the dynamic weights of all point clouds at the construction site, and then performing precise registration between the point clouds of the BIM design model and the point clouds of the construction site to obtain a precisely registered BIM design model; and fusing the precisely registered BIM design model with the GIS geographic information to achieve multi-source data collaboration and optimization of the model. The dynamic weighting mechanism constructed in this invention can more accurately measure the importance of each point cloud in the registration process, effectively distinguishing between BIM design entities representing permanent structures and a large number of temporary objects without corresponding BIM semantics.

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.
