Abstract Construction site layout planning is an activity concerned with placing temporary facilities within the construction site so as to achieve the highest possible efficiency of construction operations and thus reduce the cost of construction. This can be achieved by creating a dynamic site layout planning system that changes as construction requirements change. In this research, we introduce a 4D-BIM-based dynamic site layout planning model. To achieve the previous objective, the existing models that dealt with the site layout planning problem were reviewed. This helped identify the limitations of available models and suggestions for developing a practical site layout planning methodology. The main features of the site layout planning problem were discussed. An integrated model for solving the dynamic site layout problem using BIM technology was developed. The developed model was integrated with a schedule to develop a dynamic model. The validity of the proposed model was tested, and the strength and limitations of the proposed model were illustrated. The automated system demonstrated a dynamic approach that considers both the transition from one construction phase to another and the delaying and floating of schedule activities. Facilities are arranged continuously, where space is modeled in a coordinate system. The calculation of material quantities according to changes in the schedule and progress is facilitated by using BIM technology. Ultimately, this leads to a reduction in the effort and time spent on solving the problem, providing a more realistic solution that considers progress in construction and delays, and increasing the number of locations available for placing temporary facilities. This, in turn, improves the required optimized solution.
