Risk analysis of the in situ production of precast concrete members

Abstract

The precast concrete (PC) method has been preferred for reasons of shortening of construction time, quality assurance, and cost reduction. In addition, in situ production of PC members under equivalent production conditions can save costs while ensuring quality equal to or better than in-plant production. Despite these advantages, in situ production is being avoided due to possible risks from project management. Therefore, in order to generalize the in situ production of PC members, it is necessary to clarify the causes of the possible risks and establish responses. Therefore, the purpose of this study is to analyse the in situ production risks of PC members. The results of this study can be used to establish a systematic response plan for possible risks in the in situ production of PC members.
