Application of Information Technology for Visualizing and Optimizing Construction Project Schedule

Recently, various information technologies such as VR (Virtual Reality) and AR (Augmented Reality) are being used for visualizing construction information. Specially, BIM (Building Information Modelling) is a representative tool for IT application in construction industry. Generally, BIM uses VR and nD CAD system to visualize construction schedule data. This study develops a methodology and system to apply BIM functions using 4D CAD simulation technique for risk analysis and schedule progress monitoring in the construction industry.
