Abstract: With the development of Chinese economy, the building industry has been becoming one of pillar industries. The enormous investment of engineering construction, together with its labor-intensive character, has made building safety a serious problem. Heavy casualties and serious property loss take place every year. In order to reduce the building accident and improve the management leve...

This paper describes a demonstration system for visualisation of processes found in construction schedules of large-scale building projects. It was driven by plans to develop a new airport terminal building. The building model was virtualised and users were able to “step through” the various stages of its virtual construction. The system operates within a large screen VR theatre and allows seve...

Collaborative AEC technologies centering around component-based CAD models support architectural and structural perspectives. The construction perspective is often neglected because an important dimension for construction—time—is missing. Construction planners are forced to abstract CAD model building components into schedule models representing time. 4D-CAD (3D-CAD + time) removes this abstrac...
