This research classifies these required workspaces of activity into five categories: building component spaces, site layout spaces, people working spaces, equipment spaces and material spaces. All of these spaces change and move in three dimensions and across time throughout the construction process. Different activities may occasionally interfere with each another whilst working in the same space, causing space conflicts. In order to avoid the problem of space conflicts during the construction stage, this research develops a 4D workspace conflict detection and analysis system. Our system is implemented on top of Bentley MicroStation which supports both visualization of a 3D building model with capabilities for 3D object manipulation and information querying, and provides an API (Application Programming Interface) for functionality extensions. In this system, four types of space conflict are implemented: design conflict, safety conflict, damage conflict and congestion. Moreover, this system provides a visual environment, such as 3D visualization and 4D simulations, to present work space utilization of the ongoing project and the conflict status of activities with different colors. In this paper, the design and implementation of the 4D workspace conflict detection and analysis system is discussed and sample construction example is used to demonstrate the applicability of the system.
