A building information modeling (BIM) feedback system has at least one data system, a model presentation server system, a user device, and an information feedback database management system (DBMS). The data system receives objects posted by the model manager and then retrieves information of a building model and object mapping information, wherein the object mapping information records the relation between object identifications and the retrieved objects. Via the user device, a user views the building model and manipulates to generate feedback information, wherein the feedback information has an object data structure having the object identification and the parameters associated with the object which has the parameters to be updated. Based on the object mapping information, the information feedback DBMS requests the corresponding data system to update the parameters of the corresponding object according to the feedback information.
