Herrington stated that although the learning process was initially demanding, the time and cost of modeling the structure gave MARKET STORIES CIVIL 3D modeling helps UDOT verify critical design areas, secure public approval Cost reductions yielded 15-to-1 return on technology investment 44 • BE Magazine • Volume 2, Issue 2 The ability to render and shade each component as it was being graphically constructed helped the engineers visually inspect the structure. The principles that we discovered … led us to believe that the value of 3D design and visualization was not just as tools for large, very complex projects, but that it would bring us significant value on almost every project.

Shanon Fauerbach, P.E., editorial director, CE News 2004 BE Awards juror Project Virgin River arch bridge Organization Utah Department of Transportation BE Awards category Civil visualization Project objectives UDOT created a 3D computer model of the structure to facilitate public involvement, meet Context Sensitive Solutions requirements, and verify constructability. Fast facts The time and cost of modeling the structure in 3D gave a return on investment of 15 to 1, based on reduced change orders and construction cost savings.
