Tie project schedule to 3D model data for real-time schedule animation and review. This process visually isolates logistic challenges prior to start of construction. This type of review is currently required by the Port Authority of NYNJ and other government agencies.

4D modeling adds the dimension of time to the project team's 3D models. The introduction of change over time allows stakeholders to view logistics and sequence issues that may not be obvious in a static model.

In addition to use in project planning, firms are adopting 4D modeling and simulations for marketing purposes to display a competitive edge to potential clients.
