This paper explores how the utilization of 4D BIM can bridge the gap between actual and planned progress. The preparation of progress plans usually occurs when limited information is available, which entails revisions of schedules when new information emerges, and actual progress deviates from planned progress. When moving from pooled to sequential to reciprocal interdependencies, there is a need for more complex communication and coordination in order to prevent difficulty in obtaining information, completing tasks, and decision-making. The key to successfully using 4D is to avoid negative iterations by downscaling and planning more schematically. This includes task detailing and breaking down reciprocal interdependencies into pooled and sequential interdependencies. The findings of this conference paper indicate that increased utilization of 4D is limited due to the lack of an organizational culture investing in standardized policies and procedures for digital solutions to reveal the capability and capacity in 4D BIM-based systems.
