Assessment of Rework Risk in the Construction Process of Prefabricated Buildings Based on BWM-GRA Method
Publication: ICCREM 2023
ABSTRACT
In recent years, prefabricated buildings in China have shown good development trend. However, the advantages of prefabricated buildings in China are not yet significant, and there is an increased risk of rework compared to cast-in-place buildings. To propose effective measures to deal with the risk of rework, this study conducts a risk assessment of the prefabricated building construction process from three aspects: rework frequency, cost, and construction period. Firstly, the construction process with rework risks was determined through literature review, and the weight of rework frequency, cost, and construction period in each construction process was determined using the best worst method (BWM). Then, the grey relational analysis (GRA) method was used to construct the correlation coefficient matrix. Finally, the risk level was determined by weighted grey correlation degree, and targeted recommendations were proposed accordingly. The research conclusions provide a reference for controlling the risk of rework in the construction of prefabricated buildings in China.
