Development of Web-based Interactive 4D Block-Tower Model for Construction Planning and Scheduling Education Julian H. Kang*, Byeong-Cheol Lho**, Jeong-Hoon Kim** *Texas A&M University / **Sangji University

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.

1. Introduction

The construction planning and scheduling process is composed of multiple steps that include interpreting the given information to figure out what to build and visualizing the construction sequence to determine how to build it. In the visualization process of a construction sequence, professionals disassemble the planned structure into identifiable work packages that are logically connected. The critical path in the logical network of the work packages is then identified using Critical Path Method (CPM) and the construction schedule is illustrated using a bar chart.

The conceptual expression of the schedule may be an effective way for explaining the entire construction schedule. A graphic timetable for the Java railroad line drawn in 1937, very well demonstrates the merit of abstractness in describing multi-dimensional information 1. It expresses six different types of information sets on one sheet using the station title and inclined lines. However, a conceptual expression of the construction schedule often demands a significant amount of education and site experience. The owners or the end users of a proposed structure may experience difficulties in interpreting the schedule documents and understanding why a certain decision is made for the project.

In construction projects, a 3D expression of the proposed structure has been always considered as an effective way of explaining the designer’s goal. A 3D expression of the structures in space dates back to the early Renaissance when painters developed a set of rules for constructing realistic spatial settings known as the Perspective 2. Besides using the perspective, architects
