Conventionally, 2D paper-based CAD drawings are mainly used to view, extract, change, and exchange project information. This may lead to potential design and constructability conflicts. Through the use of 3D models in a Virtual Environment (VE), the design intent can be reviewed and modified during virtual interactive sessions, hence minimizing or even avoid conflicts. This paper presents the results of an experiment to compare and evaluate the effectiveness of five VE displays to review construction 3D models. The experiment involved using subjects from the AEC (Architecture, Engineering, Construction) industry that viewed and performed specific tasks on five construction 3D models. The five VE displays used were the CAVE™ (Cave Automated Virtual Environment), a Head Mounted Display (HMD), an Immersive-Workbench (IWB), a 1.5 meter hemispherical display and a desktop monitor. Based on the experiment results and subjects’ comments, summaries of the tradeoffs of all the VE displays were gathered and tabulated.
