碩士 === 國立臺灣大學 === 土木工程學研究所 === 93 === 4D (Four-Dimensional) simulation combine 3D (Three-Dimensional) models and building construction schedules to visually simulate the construction process of building. Through 4D simulation in engineering project management, the conflicts of space and schedule can be detected in advance. 4D simulation could also serve as an analytical tool, helping project managers to optimize project resource utilization, site logistics and safety plans. In this thesis, we have developed a prototype 4D simulation system, named the A4D system, for steel structure construction. The system presents 3D models of steel structures in the Virtual Reality environment using the X3D (eXtensible 3D) standard. In this X3D-based Virtual Reality, 3D objects communicate with outside temporal data through SAI (Scene Access Interface) to archive the integration of 3D models and construction schedules. In addition, a data file format, called A4D, that combined the X3D format and the Microsoft Project XML file format, has been developed in this work promote the sharing and exchange of 4D simulation information.
