Whole Process Engineering Consultation (WPEC) plays an increasingly vital role in modern engineering project management. It not only encompasses the entire project lifecycle from planning and design to implementation and operation but also significantly enhances project efficiency, reduces costs, and mitigates risks. As the complexity of engineering projects grows, refined management emerges as a crucial method for achieving efficient project management. This paper explores the application of refined management in WPEC and analyzes its role in project risk control through real-case studies. By delving into the principles of refined management, management tools, and risk control strategies, this study proposes an integrated approach to optimize project management processes and improve project success rates. Additionally, it discusses the impact of emerging technologies on refined management and risk control, providing insights into future development trends. The aim is to offer theoretical support and practical guidance for engineering project management, ensuring efficient management and risk control.
