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

Abstract

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.

Clash Detection or Clash Avoidance? An Investigation into Coordination Problems in 3D BIM

“…This search was carried out because multifarious benefits of ICT software to successfully impact on the construction project delivery have been widely acknowledged in literature. These include but not limited to evaluating and simulating alternative construction schedules [6], improving communication of project participants [7], improving site logistics, layout and work execution space [8], supporting management tasks [9] and improving multi-team collaborative planning [10]. What is clear from these studies is that the introduction of digital systems improves coordination, collaboration and communication among the sundry design disciplines involved in a project.…”

A Conceptual Model of Intelligent Program Management Information Systems (iPMIS) for Urban Renewal Mega Projects in Korea

“…The model is called BIM (Building Information Model). Research on an integrated project information model for collaboration (Plume and Mitchell, 2007) and decision support cooperated with 4D simulation (Fisher, 2000;Chau et al, 2005) are examples of how to implement the approach. As stated above, management systems for urban renewal mega projects would harness stateof-the-art IT in construction as well.…”

Automation in Site Management: A Qualitative Approach

“…Complex systems have been developed to cater to the need of efficient planning and management of construction site. Systems involving visual techniques to obtain a bird's eye view of the construction site as the construction progresses have also been developed [2]. They are known as 4D dynamic construction management systems, which show development of site in 3 dimensions with respect to the 'fourth dimension', that is, the time.…”
