*BIM 4D model generation and visual simulation [20].*


The 4D model allows visual representation of the planned construction process. The Simulate tab of the Timeliner the Play option should be selected in order to initialize the construction simulation animation (**Figure 11**).

The simulation can be exported through the Animation command on the Output tab and allow to monetarize the real work in the site. It is also possibility to do a

virtual navigation inside the model with the insertion of an avatar (**Figure 12**). A comparison of the evolution of construction can be represented (**Figure 12**): executed (gray), progressing (green), early (yellow) and backward (red). The ability of the BIM 4D model to be transportable to the construction site supports the control of the real construction.
