MATURING VISUALIZATION TOOLS MAKE IDEAS LOOK REAL : CONCEPTS ARE CONVEYED MORE SWIFTLY WHEN SIMULATIONS AND 3-D IMAGING COME INTO PLAY

This article outlines the use of 3-D computer imaging as an aid in conceptualizing major construction projects, including those that are seen as time-sensitive and logistically complex. Both academics and engineering firms alike use this technology to visualize, stream-line, and anticipate difficulties in larger construction projects. The computer image is generated through a combination of digital photography, isometric line drawings, and rendered images. The method of using 3-D computer imaging can also be expanded to 4-D, which includes time and scheduling points into the virtual representation of projects. An example of application to transportation engineering is included which describes the difficulties allayed by 3-D rendering in the instance of a time-sensitive repair to a railway link between London and the Channel Tunnel in 2004. The technology aided in speeding up the project, which was apparently impossible to complete in time, allowing it to finish 14 hours ahead of schedule.
