Schedule delays in construction projects are key issues affecting the successful delivery of projects. The factors causing delays are complex, diverse, and interrelated, directly leading to increased costs and resource waste. This paper systematically analyzes the main causes of construction project schedule delays, including internal management deficiencies, external environmental changes, and unreasonable resource allocation, and deeply explores the impact mechanisms of different factors on schedule control. On this basis, targeted coping strategies are proposed, such as strengthening project plan management, optimizing resource allocation, and enhancing risk early warning and communication and coordination, so as to improve the controllability and execution of project schedules. The study aims to provide theoretical support and practical guidance for construction project management practices and promote the on-time and high-quality completion of projects.
