The invention discloses a quality tracking system and method based on a BIM model. The system comprises a first electronic tag, a second electronic tag, a third electronic tag, an electronic tag reader I, a positioning device, a server and a BIM system, Wherein the first electronic tag reader is used for identifying information in an electronic tag and uploading the information to the server; Thepositioning device is used for measuring real-time coordinates of the positioning chip and uploading the real-time coordinates to the server; The server is used for receiving base station data, calculating the operation path of the positioning chip and determining the concrete pouring area and the average concrete pouring height in the concrete transport vehicle. And the BIM system is used for drawing a newly poured building BIM sub-model and associating the BIM sub-model with the concrete information and the test block detection report information. According to the system and method, qualitytracking based on the BIM model can be achieved, whether the concrete pouring position information is matched with the pump truck pouring position information or not is judged, and path guiding of theconcrete transport vehicle is achieved.
