4D planning allows simulation of demolition and construction activities to eliminate delays and sequencing problems. State-of-the-art software provides a dynamic link between the project model and the project management software. Using the fourth dimension of time in conjunction with the 3D model, conflicts can be discovered and solved before construction begins. This highly visual review format increases design acceptance from all stakeholders in the food manufacturing environment.

For many projects, reducing production downtime is critical. 4D planning provides a critical view of the sequence of events within a project and offers the best opportunity to reduce production downtime.
