BIM-based digital engineering supervision method and system

The invention relates to the technical field of BIM digitization, in particular to a BIM-based digitization engineering supervision method and system, and the method comprises the following steps: 1, setting at least one upper computer for constructing and supervising a three-dimensional simulation engineering model and a plurality of independent portable lower computers capable of carrying out remote data interaction with the upper computer; a person remotely operating the upper computer can make a mark on the three-dimensional simulation engineering model in real time according to a feedback file package, the feedback file package comprises an engineering model plane graph marked with the positions of quality and safety problems, and a patrol problem description graph can be planned according to the quality and safety problems. Therefore, the efficiency of a worker who remotely operates the upper computer to accurately mark the condition of the construction site can be greatly improved, and paperless manage
