The author elaborates the problems that will influence the quality of the engineering existing in the construction technology, the operation requirements, and the quality control and other aspects in each procedure of the construction process of the EPS external thermal insulation system, and puts forward the corresponding control measures for the construction technologies, and puts forward the measures for the construction management in the aspects of the materials and the quality inspection and so on. Through the combination of the control of the construction technologies and the management on the construction qualities, the EPS external thermal insulation system can meet the requirements of the functions in the aspect of the construction.
