Also Through comparative analysis method selected 4 control charts suitable for construction project quality control from 8 conventional control charts. Finally, this paper Propose that according to control charts to find out the reason of abnormal factors can not improve the quality of the construction project, only for the different abnormal reasons to take effective measures can truly dynamic achieve the purpose of quality control of the course of construction project.
