Abstract
Four dimensional models have been proven to be an effective tool for construction management. The 3D models within these change color according to changes in its corresponding construction schedule. Color schemes play a crucial role in the designing and representation of a 4D model. Good color schemes enhance an engineer’s understanding of the situation at hand. Therefore, this research aims to develop effective and affordable methods of selecting and evaluating color schemes in 4D models. We proposed a two-step method of color selection. The first step is to determine the number of construction statuses and their relationships with each other. The second step is to select the colors to fit these statuses. In this research, we also developed three types of simulators to facilitate color evaluation. The display simulator is the first type of simulator and includes a LED monitor simulator, a projector simulator and a print-out simulator. The second type of simulator is the viewer simulator which simulates protanopic blindness and tritanope blindness. The third type of simulator is the rendering simulator. This simulates the rendering results from the two major 3D viewers, NavisWorks and SmartPlant Review. Using the two-step selection method and the three types of simulators, we identified 21 colors schemes (3 for 3 statuses, 12 for 5 statuses and 6 for 6 statuses) ideal for presenting 4D models. We summarized our experiences by providing 6 guidelines for color selections. The color schemes and simulators were also implemented as a reference tool on a website (http://4Dcolor.caece.net). Future 4D model builders can refer to this website to select the color scheme which is most appropriate for their projects.
