Abstract

As China's construction industry advances its transformation and upgrading, prefabricated construction has gained widespread adoption as a green, low-carbon, and efficient building method. In actual project management, however, prefabricated construction often faces challenges such as poor process integration, inefficient management, and difficult cost control due to its involvement in multiple stages including component design, production, transportation, hoisting, and on-site construction. This paper focuses on construction process optimization and cost analysis to explore the characteristics and challenges of prefabricated building project management. It identifies key issues such as complex construction organization, difficult supply chain coordination, and high on-site management requirements. It proposes process optimization pathways across three dimensions—design-construction integration, supply chain and logistics management, and construction organization with on-site management—emphasizing the vital role of BIM technology and digital tools in enhancing collaborative efficiency. The paper analyzes the cost structure of prefabricated construction and suggests strategies for cost reduction and efficiency gains through standardized design, scaled production, and comprehensive, meticulous management throughout the entire process. Scientific construction process optimization not only shortens project duration and improves quality but also effectively reduces overall costs, providing management insights and practical references for promoting prefabricated construction.
