Design—Construction Phase Safety Risk Analysis of Assembled Buildings

To reduce the impact of safety risks on assembled buildings, this paper explores the factors affecting the safety risks of constructed buildings from the perspective of linkage between the design and construction phases. The method identifies 10 first_level risk indicators and 25 s-level safety risk indicators in five dimensions of prefabricated components, personnel, management, environment, and technology in both the design and construction phases, utilizing literature induction, expert interviews, questionnaire surveys, and Porter’s diamond model. The structural equation model was used to quantify the weights of the 25 s-level safety risk indicators to highlight the safety risk analysis of the assembled building and avoid risk. The results of the study show that it is important to analyze the safety risk linkage between the design phase and construction phase of the assembled building; from the perspective of the design-construction phase linkage, controlling the safety risk in the design phase can effectively reduce the safety risk in the construction phase.
