Incorporate The 4th D – Time


4D models
4D models support the understanding project phasing. 4D models, which combine a

3D model with time, allow the Architects, Engineers, and Contractors to communicate

project phasing to all stakeholders and facilitate value engineering scenarios.

This allows owners to choose the best combination of up-front costs and future economies. With 4D

modeling, the stakeholders are better able to understand how the project affects them
(e.g. – where the construction zones will be, where and when tenants will have to move to

swing space, etc.), as well as to understand the projected construction schedules for funding purposes

. 4D modeling can help to get a project back within its budget and keep it there.
