Three‐dimensional (3‐D) CAD and walk‐thru are promising technologies in design and construction. While gaining widespread acceptance in design, the use of 3‐D and walk‐thru during the construction phases of projects is evolving slowly. One significant barrier to acceptance includes lack of documented cost/benefit analysis. Experimental results reported herein provide quantitative evidence of the advantages of 3‐D CAD and walk‐thru for planning construction projects. The results provide strong evidence of the practical benefits and appropriate areas of application for 3‐D CAD and walk‐thru technology.
