4D dynamic construction management and visualization software: 1. Development

With the increasing complexity of modern construction projects, there is a pressing need on higher degree of assistance from computer in order to accomplish effective planning and management. This paper delineates the previous development and implementation of a prototype four-dimensional site management model (4DSMM), with the objectives to address the requirement for linking scheduling data to a three-dimensional computer graphics building model and to furnish the capability for planners to view graphic simulations of the construction process at any prospective specified date. Through the development and various real site trials in these few years, this prototype model extends 4D technology into areas of resource management and site space utilization, in addition to planning of building construction solely. In this study, a new information system platform, graphics for construction and site utilization (GCPSU), has been developed to implement the model 4DSMM. The characteristics of the prototype system, including the integration of dynamic resource management at the project level and decision-making support, and the underlying techniques, employed in the model to facilitate and tailor the construction management practice, are presented.
