The invention discloses a construction progress prediction method and
system based on a BIM model. The method comprises the steps of obtaining construction information so as to construct a triple-level model, and the triple-level model comprises a
macro model, a meso model and a micro model; establishing a construction progress plan, and linking the construction progress and the triple-level model so as to generate four-dimensional progress
simulation; according to four-dimensional progress
simulation, building a construction task
decomposition structure so as to formulate construction plans of different levels, according to the project content, adding construction tasks and progress plans step by step into the
construction plan to form a four-dimensional construction
simulation model; according to the four-dimensional construction simulation model, guiding the progress construction progress, displaying each work of the construction process in the visualized object building component virtual
building process, adding the time dimension, and on the basis of real-time mathematical
statistical analysis, simulating the problem in the construction process; from macroscopic to mesopic, and then microscopic substep modeling is performed, different-level models can be switched through clicking operations, and convenience is greatly improved.
