The use of visualization and animations 4D helps to gain a better understanding of the project. Phasing simulations, created to understand time-based processes, enables clients to foresee issues and assess potential solutions. 4D links the 3D model with the time factor of the construction schedule. In BIMeng we link each item or activity to a Gantt diagram generated with software such as Microsoft Project or Privamera to the 3D model.
The 4D model shows the construction sequence plan set against time. The aim of the phasing simulation is to assist the construction team in visualizing possible issues or inefficiencies. The simulation improves management and information exposing situations such as out-of sequence work, modifications impacts, scheduling conflicts between multiple trades, all in order to achieve the optimization of the construction schedule.
The fifth dimension 5D is cost added to the virtual building 4D.
