Abstract
Abstract Current studies on 5D CAD have been limited to either description of concept or automatic generation of quantities. Few have attempted to explore the other capabilities of 5D CAD. Project cost control and schedule control are very important for successful project delivery, while existing studies on computer based project control tools have largely focused only on schedule control. This paper fills the gap by investigating the possibility of using 5D CAD for project cost and schedule control. Initiated by Woodside Energy Ltd, a prototype of a 5D CAD system has been developed specifically for Liquefied Natural Gas (LNG) industry. The system was tested with the project data of an example module from an LNG plant provided by Woodside Energy Ltd. The functions of the system include: visualization of schedule data and verification of cost in real time and facilitation of periodic planning and progress reporting. It is concluded that 5D CAD could be a very powerful project cost and progress control tool.
