4D Phasing - The office of the Chief Architect is Currently encouraging, documenting, and evaluating 3D, 4D, and building information modeling (BIM) technologies on a project-by-project need basis. The 4D construction model of construction and tenant phasing revealed inefficiencies of schedule and communicated what the schedule needed to look like to the contractor, 4D models, which combine a 3D model with time, allow Architects and Engineers, contractors to communicate the proposed project phasing to all stakeholders. With 4D modeling, these stakeholders are able to better 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.).

Pinnacle Infotech is also able to use 4D models to better understand projected construction schedules for support purposes.

4-D schedules are a powerful tool for phasing, coordinating, and communicating planned work to a variety of audiences, including project stakeholders and those directly responsible for executing the work.
