Ltd.10.26689/jwa.v9i2.10300ArticleResearch on Key Stages and Control Strategies of Whole-Process Cost Management in Agency-Built Projectshttps://artdesignp.com/journal/JWA/9/2/10.26689/jwa.v9i2.10300HuMinjie2025922025-04-28Against the backdrop of the increasingly complex construction market environment, the whole-process cost management of agency-built projects faces issues such as cost overruns and insufficient management efficiency due to the numerous stages and high technical requirements involved. This paper focuses on the key stages of whole-process cost management in agency-built projects, including project initiation, design, construction, and completion. It proposes strategies to optimize the cost management process and enhance management efficiency, providing theoretical support and practical guidance for the whole-process cost management under the agency-built model.
