Abstract：
As the housing industrialized standard system is improved, the study of standardization management system is also more and more important. Based on WBS of the general engineering construction project, according to the different production assembly work content in factory and in site, the paper add to the four stages of process engineering of industrialized housing system which contains level 1 factory, level 2 factory, level 3 factory and on-site installation phase, and achieve the WBS work breakdown of which In the form of standard form.
