4D adds the time factor of the construction schedule to the 3D model. ENGworks links each activity of a Gantt chart to the BIM.
These animated models represent the planned construction sequence set against time. The main purpose of a construction phasing simulation is to provide a tool that will help the construction team visualize logistical issues or inefficiencies, exposing details such as out-of-sequence work or scheduling conflicts between multiple trades, analyze “what if” scenarios and macro-level construction phasing strategies, all in order to achieve the optimization of the construction schedule.
