There have been many policy documents in state-, province- and city-levels about the development of prefabricated buildings in recent years, which are aiming at promoting the application of prefabricated buildings. Currently, the prefabricated buildings can be built by two forms of fully prefabrication and partial prefabrication, in which the latter one is of more applications in the industry. This paper introduces the construction progress of a certain partial prefabricated building project, and sorts out the problems related to the construction of partial prefabricated building. Relevant opinions and suggests are promoted that, in the design stage, the overall planning of PC component application deserves more attention to be paid, and that effective transformation of design drawings should be noticed in the implementation stage to connect the design, production and construction processes. Only by strictly controlling the quality of PC components, can the superiority of assembly building technology be brought into full play.
