Session 1121 Development of Web-based Interactive 4D Block-Tower Model for Construction Planning and Scheduling Education

For construction projects implemented in a congested area, the ability to understand spatial relationship between structures is expected to play an important role in construction planning and scheduling. However, students can hardly understand the time-space relationship at the job site using a CPM network or a bar chart. Research shows that visual representation of the construction sequence helps to detect logical errors in the construction schedule. Therefore, a 4D construction model, which depicts the construction sequence in the 3D world is expected to help students learn time-space relationship in the construction schedule more effectively. Also, by disseminating the 4D construction model over the Internet, students will learn the time-space issues in construction planning and scheduling at their own pace. We developed a Web-based interactive 4D block-tower model in order to teach time-space issues in construction planning and scheduling more effectively. This paper addresses the process of developing a Web-based interactive 4D block-tower model and how it could improve teaching time-space relationship in the construction schedule
