A Review on Construction Quality Management of Prefabricated Housing in Xi’an

Abstract

China's construction industry, despite over 30 years of development since the reform and opening-up period, remains largely traditional, characterized by outdated construction methods and labor-intensive practices. However, with the gradual disappearance of the "demographic dividend," the industry is facing a growing labor shortage. To adapt to the demands of new urbanization, industrialization, and informatization, as well as to align with the "dual carbon" development strategy and promote construction industrialization, China has been vigorously developing prefabricated residential projects. While significant progress has been achieved under supportive policies, the industry is still in a transitional phase from traditional to industrialized construction methods, with construction quality requiring further improvement. Considering the potential of contractor’s perspectives to enhance construction quality management, this study explores the evaluation of construction quality management in prefabricated residential projects through the lens of contractors.

This study systematically reviews the fundamental theories of construction quality management evaluation for prefabricated residential projects and identifies initial evaluation indicators based on the characteristics of these projects through a literature analysis method. Subsequently, expert surveys are employed to finalize the evaluation indicators, establishing a contractor-based evaluation indicator system for construction quality management. The study then applies the Analytic Hierarchy Process (AHP) to calculate the weights of indicators at both the criterion and indicator levels and develops a construction quality management evaluation model using the fuzzy matter-element analysis method.

The research results of this article provide an important basis for contractors to conduct quality management evaluations.
