6. Bridges are modelled and these models are tested using sophisticated software before being presented for construction. The software enables the architect to: • define the shape of the bridge • apply parameters such as width, length and material to the structure • view the bridge from different perspectives • test the strength and stability of the bridge under all conditions. The architect starts by defining the basic shape of the required bridge. This includes the span of the bridge (from one end to the other), and the struts (pillars) that are needed to support the bridge. During this phase the architect has a wire frame image to work with. When the design is complete, the image is rendered to give a solid view of the bridge.
