Planning plays a critical role in the successful execution of building construction projects because it provides a systematic approach for organizing project activities, managing resources, and controlling project performance. Effective planning enables project managers to define project objectives, prepare realistic schedules, and coordinate construction operations in an organized manner. Traditional planning techniques such as Work Breakdown Structure (WBS), Gantt charts, Critical Path Method (CPM), and Program Evaluation and Review Technique (PERT) have long been used to improve project scheduling and activity coordination. In recent years, modern technological tools such as Building Information Modeling (BIM), digital project management systems, and automated planning approaches have further enhanced the efficiency and accuracy of construction planning. These technologies support better project visualization, improve communication among stakeholders, and assist in monitoring project progress more effectively. This review paper examines the major methods, techniques, and modern approaches used in planning for building construction projects. The study highlights how proper planning contributes to improved resource utilization, reduced project delays, and better decision-making throughout the construction process. It also discusses key challenges faced in construction planning and emphasizes the importance of integrating traditional planning techniques with modern digital tools to achieve more reliable and efficient building construction projects.
