Analysis of key risk factors for prefabricated building projects based on social network analysis

This is the authors' abstract. We don't add key points for this paper.

With the continuous development of prefabricated buildings, their quality issues are getting more and more attention. With a view to improving the risk management of the qualitative aspects of prefabricated buildings, determine the whole process quality risk indicators for prefabricated buildings from the whole life cycle. Risk factors are identified through literature research and questionnaire survey method, and the whole process quality risk assessment model of prefabricated building is constructed based on social network analysis. Combined with the specific quality risk indicators network role analysis to determine the key risks, the study found that the design and construction stages are where key risk factors are most likely to be present, respectively, the design of the actual constructability is poor, the design of the integration is insufficient, the field workers are inexperienced in construction, the actual feasibility of the construction is poor, the construction equipment is not advanced enough. Targeted coping strategies are proposed according to the key risks.
