4D dynamic management for construction planning and resource utilization

The requirements, nowadays, for more effective planning and management assistance from computer have become even more demanding. In this paper, our 4D model, 4D Site Management Model+ (4DSMM+), is described, a model developed in an attempt to address the requirement for linking scheduling data to a 3D computer graphics building model, which will allow planners to perform graphic simulations of the construction process. Compared to other 4D models and our earlier research, the current model extends 4D technology into the areas of resource management and site space utilization, in addition to the planning of building construction. A new information system platform, 4D Management for Construction Planning and Resource Utilization (4D-MCPRU), has been developed in this research, in order to implement the model 4DSMM+, which integrates dynamic resource management at the project level and decision-making support with the other features. This paper discusses features of the newly extended model and describes the underlying techniques needed for applying the model in construction management practice.
