BIM model and WBS task association method and device

The invention relates to a BIM model and WBS task association method and device. The method comprises the following steps: acquiring project information of an engineering project, classifying construction tasks of the engineering project according to the project information, and acquiring a WBS task of the engineering project; performing parameter analysis and classification on the WBS task to obtain a parameter classification result of the WBS task; the parameter classification result comprises professional parameters, position parameters and acceptance parameters; mapping the parameter classification result by adopting a BIM model to obtain an association result of the BIM model and the WBS task; the BIM model is a model which has extensible attributes and is added with a mapping code. According to the method, mapping of the WBS task classification information can be achieved through the construction task classification information of the BIM model, automatic association of massive BIM models and WBS task i
