Construction Quality of Prefabricated Buildings Using Structural Equation Modeling

Abstract

Prefabricated construction has emerged as an inevitable trend in the development of the construction industry due to its numerous advantages, such as safety, energy saving, environmental protection, and sustainability. However, a series of operations and processes, such as prefabricated components, transportation of finished products, and on-site lifting required for fabricated buildings, can affect the quality of prefabricated buildings, especially during the construction process. This study aims to establish a systematic approach to analyzing the factors that influence the construction quality of prefabricated buildings and their interrelationships. A questionnaire was issued based on a literature review, and a model of the factors that influence the construction quality of fabricated buildings was established using structural equation modeling. Results showed that construction organization and management have a significant impact on building quality, prefabricated components, and the construction process. Moreover, they exerted the greatest influence on building quality, unlike the traditional belief that the construction process primarily affects building quality, and identified core factors influencing the quality of prefabricated construction.
