4D CAD SYSTEM (4 Dimensional Construction Simulation System)
JGC has originally developped 4D CAD SYSTEM and put it to practice for more than 10 years.
There are two technologies within the 4D CAD SYSTEM, one is "Construction Method Dynamic Simulation" that has been built by combining the data of construction equipment, obstacles under construction etc, and the 3D CAD model data, and the other is "Schedule Visual Simulation" that has been built by combining the schedule data from the general schedule network tool and the 3D CAD model data.
